     This application is the National Stage of PCT International Application No. PCT/DE2006/001873, filed Oct. 21, 2006, which application published in German and is hereby incorporated by reference in its entirety, which application claims priority from German Patent Application No. DE 10 2005 053 597.6, filed Nov. 10, 2005 which is incorporated by reference in its entirety. 
     FIELD OF THE INVENTION 
     The invention relates to a hydrodynamic torque converter device for a motor vehicle drive train, comprising a torsion vibration damper and a converter torus formed by a pump shell, a turbine shell, and a stator shell, and comprising a converter lockup clutch. 
     BACKGROUND OF THE INVENTION 
     FIG. 4 of German Patent No. DE 103 58 901 A1 shows a hydrodynamic torque converter device for a motor vehicle drive train comprising a torsion vibration damper comprising two energy accumulator means, thus spring means, connected in series, and a converter torus formed by a pump shell, a turbine shell, and a stator shell, and a converter lockup clutch. 
     With reference to the radial direction of the rotation axis of the torsion vibration damper, the two energy accumulator means are radially offset from one another, so that one of these energy accumulator means forms an inner energy accumulator means and the other one forms an outer energy accumulator means. In the moment flow between the two energy accumulator means, an intermediary component is disposed, which is non-rotatably connected to the turbine dish of the converter torus, wherein the intermediary component in this configuration forms the output component of the outer energy accumulator means and the input component of the inner energy accumulator means. 
     The converter lockup clutch comprises an axially movable piston, which is provided with a friction liner on its side, facing the converter housing, so that it can be pressed against the converter housing for closing the converter lockup clutch. The piston, thus, simultaneously forms an input component of the radially exterior energy accumulator means and comprises actuation elements for loading the energy accumulators of the outer energy accumulator means. 
     The actuation elements initially extend with reference to the axial direction of the torsion vibration damper formed by the rotation axis of the torsion vibration damper axially offset to the outer energy accumulator means into radially external portions of the energy accumulators, where they form elbows and subsequently extend with a respective inclination to the radial inside into the portion of the energy accumulator front face, for whose respective loading they are provided. With reference to FIG. 4 of DE 103 58 901 A1, these actuation elements thus extend respectively from the radial outside or from the top to the respective face side of the respective energy accumulator of the outer energy accumulator means. 
     FIGS. 5 and 6 of DE 103 58 901 A1 show hydrodynamic torque converter devices in which the actuation elements are formed at an input component of the outer energy accumulator means, which is non-rotatably connected to a piston of the type through pinions and wherein the actuation elements extend with reference to the rotation axis of the torsion vibration damper axially in the radial center of the respective energy accumulator means of the outer energy accumulator means to the respective face side of the energy accumulator, which can be loaded by the respective control element. Thus, the control elements extend in the radial center with reference to FIGS. 5 and 6 of DE 103 58 901 A1, or from the side to the respective face side of the respective exterior energy accumulator. 
     Thus, it is the object of the invention to provide a hydrodynamic torque converter device for a motor vehicle drive train, comprising a torsion vibration damper and a converter torus formed by a pump shell, a turbine shell, and a stator shell, and comprising a converter lockup clutch, wherein the hydrodynamic torque converter device is simple to manufacture and facilitates the safe compensation of rotational spikes of a combustion engine, when integrated into a motor vehicle drive train, or facilitates only a minor transfer in the direction towards the drive axle(s) of the motor vehicle. 
     BRIEF SUMMARY OF THE INVENTION 
     The present invention is a hydrodynamic torque converter device for a motor vehicle drive train, comprising a torsion vibration damper, a converter torus formed by a pump shell, a turbine shell, and a stator shell, and a converter lockup clutch. 
     It is appreciated thus that a means designated as “converter torus” in the previous publications is partially designated as “hydrodynamic torque converter”. The term of the “hydrodynamic torque converter” however, is partially also used for devices in previous publications, which comprise a torsion vibration damper, a converter lockup clutch, and a means formed by a pump shell, a turbine shell, and a stator shell, a converter torus in the language of the present disclosure. In view of this, the terms “hydrodynamic torque converter device” and “converter torus” are used in the present disclosure for better identification. 
     The torsion vibration damper comprises a first energy accumulator means and a second energy accumulator means. The first energy accumulator means comprises one or several first energy accumulators and the second energy accumulator means comprises one or several second energy accumulators. The converter lockup clutch, the first energy accumulator means, and the second energy accumulator means are connected in series. It is thus provided that when the converter lockup clutch is closed, the first energy accumulator means is disposed in the torque flow between the converter lockup clutch and the second energy accumulator means. 
     Between the first energy accumulator means and the second energy accumulator means, at least one intermediary component or first component is provided, which is connected in series with the two energy accumulator means. Thus, it is provided that a torque, which may be transferred by the converter lockup clutch, when the converter lockup clutch is closed, can be transferred by the first energy accumulator means to the at least one intermediary component or first component and can be transferred by this intermediary component or first component through the second energy accumulator means in the direction of the output side of the hydrodynamic torque converter device. 
     The turbine shell of the converter torus comprises an outer turbine shell. The outer turbine shell is, e.g., non-rotatably coupled to the intermediary component or to the first component, e.g., by several driver components non-rotatably coupled amongst each other, or by one driver component. It can, however, also be provided that such a driver component or a section or extension of the outer turbine shell forms the intermediary component or the first component or one of several intermediary components or first components, by which torque can be transferred from the first energy accumulator means to the second energy accumulator means at least when the torque converter lockup clutch is closed. It can furthermore be provided that the outer turbine shell or an extension of the outer turbine shell forms the intermediary component or one intermediary component, or first component, through which torque can be transferred from the first energy accumulator means to the second energy accumulator means, at least when the torque converter lockup clutch is closed. 
     Furthermore, an input component of the first energy accumulator means is provided. By the input component of the first energy accumulator means or through the input component of the energy accumulator means, a transferable torque can be transferred by the torque converter lockup clutch, when the torque converter lockup clutch is closed, to the first energy accumulator means for loading the first energy accumulator means. The input component of the first energy accumulator means comprises, respectively, at least one ear forming a free end and a non-free end for loading a respective face side of a respective first energy accumulator. It is thus also provided in particular that the input component for each first energy accumulator of the first energy accumulator means comprises one or at least one ear, by which the respective energy accumulator can be loaded on the input side or on the input side of the first energy accumulator means. 
     The respective non-free end of a respective ear is disposed radially within the free end of the respective ear with reference to the radial direction of the rotation axis of the torsion vibration damper. 
     In a preferred embodiment, the free end and the non-free end of an ear of the input component of the first energy accumulator means, provided for loading a first energy accumulator of a first energy accumulator means, are disposed so that a straight connection line extending through the free end, through any point or the center of the free end and the non-free end, through any point, or through the center point of the non-free end, encloses an angle with a straight line extending in radial direction relative to the rotation axis of the torsion vibration damper, which has an absolute value of less than 70°, preferably less than 60°, preferably less than 50°, preferably less than 40°, preferably than 30°, preferably less than 20°, and most preferably less than 10°. This applies preferably for each ear of the input component of the first energy accumulator means, provided with a free end and with a non-free end, and provided for loading a respective front face or front side of a respective first energy accumulator of the first energy accumulator means. 
     It is thus provided in particular that at least one ear of the first input component of the first energy accumulator means provided for loading a in particular input side front face, or front side of a first energy accumulator of the first energy accumulator means extends, so that the projection of the ear into a projection plane defined by the face side intersects the outer circumference of the face side projected into the projection plane at least once. It can thus be provided that the outer circumference of the face side is disposed in the projection plane anyhow, so that the projected outer circumference is identical to the non-projected outer circumference, or that the outer circumference is at least partially disposed outside of the projection plane, which can, e.g., be the case when the front face or front side is not, or not exactly disposed in a plane. For simplification purposes, the terms “projected outer circumference” and “projected ear” are used, wherein the projections relate to the projection plane. Since the projected ear intersects the projected outer circumference of the face surface or face side in the projection plane at least once, the projected outer circumference and the projected ear form one or several intersection lines in the projection plane. This occurs in particular in the case, when the projected ear intersects the projected outer circumference of the face surface or face side exactly once in the projection plane, the projected outer circumference and the projected ear forming exactly one intersection line in the projection plane, and in the case when the projected ear intersects the projected outer circumference of the front face or front side several times in the projection plane, the projected outer circumference and the projected ear forming several intersection lines in the projection plane, which extend along the projected outer circumference of the front face or front side, extending offset from one another or overlapping or abutting to one another. Thus, an intersection line exists in the case, where as described, only one intersection line is formed, and also in the case, where several intersection lines are formed, wherein the intersection line is generated by the projected ear, intersecting the projected outer circumference for the first time along its extension, viewed from its non-free end to its free end, and wherein the intersection line is designated herein as the first intersection line for better identification and for simplified reference. The first intersection line is disposed in the projection plane with reference to the radial direction of the rotation axis of the torsion vibration damper in a radially inward portion of the respective first energy accumulator and thus in particular in its entirety. The first intersection line is disposed radially within the center force effect line of the respective first energy accumulator with reference to the radial direction of the torsion vibration damper, or radially within the point, at which the center force effect line intersects the projection plane and in particular in its entirety. 
     The outer circumference of the face side of the first energy accumulator is preferably a circumference defining the face side radially to the outside with reference to the advantageously provided radial direction of the face side. 
     In an advantageous improvement, each ear of the input component of the first energy accumulator means provided for loading a respective, in particular respectively input side face surface or -side of a respective first energy accumulator of the first energy accumulator means extends in the manner, wherein thus the projected outer circumference of the face surface or -side of the first energy accumulator, or this face surface or -side belongs to the respective first energy accumulator, which can be loaded by the respective ear. This accordingly applies also to the improvements and the improving features described therein, which thus can or shall relate to an ear, or in particular with reference to the respectively associated first energy accumulator, which can be loaded by the respective ear, to all ears of the input component of the first energy accumulator means. 
     It is appreciated that the projections are in particular projections perpendicular to the respective projection plane, or projections, which are substantially projected into the projection plane along imaginary circles extending concentric about the rotation axis of the torsion vibration damper. 
     According to a preferred improvement, the first intersection line is disposed in particular completely in the projection plane with reference to the radial direction of the rotation axis of the torsion vibration damper, in a radially inner portion of the respective first energy accumulator, so that the first intersection line is disposed in the projection plane with reference to the radial direction of the rotation axis of the torsion vibration damper radially within the center force effect line of the first energy accumulator, or radially within the point, where the force effect line intersects the projection plane, and thus within a portion extending mirror symmetrical about a radial straight line extending through the force effect line, or the respective point, which covers viewed in circumferential direction of the projected face surface or -side maximally 140°, preferably maximally 120°, preferably maximally 100°, preferably maximally 80°, preferably maximally 60°, and most preferably maximally 20°. 
     In a preferred embodiment, the first energy accumulator means comprises first energy accumulators, which are distributed, or spaced apart along the circumference with reference to the circumferential direction of the rotation axis of the torsion vibration damper. Such first energy accumulators can, e.g., be configured as coil springs, or as arc springs or as straight compression springs. The first energy accumulator can thus be in particular a first spring means. It is furthermore preferred that the second energy accumulator, which is, e.g., a second spring means, comprises a plurality second energy accumulators, which are with reference to the circumference direction of the rotation axis of the torsion vibration damper disposed distributed and/or spaced apart along the circumference. The second energy accumulators are coil springs in an advantageous embodiment, or straight compression spring or arc springs. In a particularly preferred embodiment, the first energy accumulators are arc springs and the second energy accumulators are straight compression springs. 
     In a particularly preferred embodiment, one or the respective ear of the input component extends so that it comprises a section between its non-free end and its free end, in which it extends straight. It can, e.g., be provided that the ear comprises such a section in its projection into the projection plane in the portion defined or enclosed by the projected outer circumference of the face surface loaded by it, wherein the ear extends in a straight line in the section. The straight section can, e.g., extend in radial direction with reference to the radial direction of the rotation axis of the torsion vibration damper and in particular, so that its projection into the projection plane extends therein through the center force effect line, or through the point or through the intersection point, formed by the force effect line and the projection plane. 
     In a particularly useful configuration, such straight section of the ear extends to the free end of the ear. It can be provided in particular also in ears forming a straight section, that a connection path, which connects a point of the first intersection line with a point of the free end of the respective ear in the projection plane, encloses an angle with a straight line, extending radially with reference to the radial direction of the rotation axis of the torsion vibration damper, through the center force effect line of the respective first energy accumulator or through the intersection point formed by the force effect line in the projection plane, wherein the angle is less than 50°, preferably less than 40°, preferably less than 30°, preferably less than 20°, and most preferably less than 10°. 
     In a particularly preferred embodiment, the respective ear of the input component of the first energy accumulator means extends, so that it can load the face surface with reference to the radial direction of the face surface of the first energy accumulator in radially substantially opposed, radially substantially exterior portions of the face surface, in particular engaging respectively therein. It is provided that the torsion vibration damper is rotatable about a rotation axis. 
     These and other objects and advantages of the present invention will be readily appreciable from the following description of preferred embodiments of the invention and from the accompanying drawings and claims.

     At the outset, it should be appreciated that like drawing numbers on different drawing views identify identical, or functionally similar, structural elements of the invention. While the present invention is described with respect to what is presently considered to be the preferred aspects, it is to be understood that the invention as claimed is not limited to the disclosed aspects. 
     Furthermore, it is understood that this invention is not limited to the particular methodology, materials and modifications described and as such may, of course, vary. It is also understood that the terminology used herein is for the purpose of describing particular aspects only, and is not intended to limit the scope of the present invention, which is limited only by the appended claims. 
     Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood to one of ordinary skill in the art to which this invention belongs. Although any methods, devices or materials similar or equivalent to those described herein can be used in the practice or testing of the invention, the preferred methods, devices, and materials are now described. 
       FIGS. 1 ,  2 , and  3  show various embodiments of hydrodynamic torque converter device  1  according to the invention.  FIGS. 1   a ,  2   a,  and  3   a,  respectively, show an enlarged view of a portion of  FIGS. 1 ,  2 , and  3 , respectively. 
     Hydrodynamic torque converter device  1  is intended for a drive train of a motor vehicle or forms a component of a drive train of a motor vehicle, which is schematically emphasized by the reference numeral  2 . Hydrodynamic torque converter device  1  comprises torsion vibration damper  10 , converter torus  12  formed by pump shell  20 , turbine shell  24 , and stator shell  22 , and it comprises converter lockup clutch  14 . Torsion vibration damper  10 , converter torus  12 , and converter lockup clutch  14  are received in converter housing  16 . Converter housing  16  is connected in a substantially non-rotatable manner to drive shaft  18  combustion engine, which can, e.g., be the crank shaft or the engine output shaft of a combustion engine. 
     As discussed, converter torus  12  comprises a pump or pump shell  20 , stator shell  22 , and turbine or turbine shell  24 , which interact in a known manner. In a known manner converter torus  12  comprises converter torus cavity or torus interior  28 , which are provided for receiving oil, or an oil flow through. Turbine shell  24  comprises turbine dish  26 , which forms wall section  30  directly abutting to converter interior  28  and defining converter interior  28 . Subsequent to wall section  30  directly abutting to torus interior  28 , extension  32  of turbine dish  26  adjoins. Extension  32  comprises straight or annular section  34 . Straight section  34  of extension  32  can be provided, so that it is substantially straight in radial direction of rotation axis  36  of torsion vibration damper  10  and so that it is disposed in particular as an annular section in a plane disposed perpendicular to rotation axis  36  or establishes the plane. 
     Torsion vibration damper  10  comprises first energy accumulator means  38 , which is provided in particular as a spring means and second energy accumulator means  40 , which is provided in particular as a spring means. 
     It is provided according to the embodiments according to  FIGS. 1-3 , that first energy accumulator means  38  comprises plural first energy accumulators  42  in a circumferential direction extending about rotation axis  36 , which are in particular arranged at a distance from one another, like, e.g., coil springs or arc springs. It can be provided that all first energy accumulators  42  are configured identically. It can also be provided that differently configured first energy accumulators  42  are provided. 
     Second energy accumulator means  40  comprises several second energy accumulators  44 , respectively, e.g., provided as coil springs or straight compression springs. Thus, in a preferred embodiment, several second energy accumulators  44  are disposed with reference to the circumferential direction of rotation axis  36  at a distance relative to one another. It can be provided that second energy accumulators  44  are respectively provided identical. Different second energy accumulators  44 , however, can also be configured differently. 
     According to the embodiments shown in  FIGS. 1-3 , second energy accumulator means  40  is disposed with reference to the radial direction of rotation axis  36  radially within first energy accumulator means  38 . First energy accumulator means  38  and second energy accumulator means  40  are connected in series. Torsion vibration damper  10  comprises first component  46 , which is disposed between first energy accumulator means  38  and second energy accumulator means  40 , or connected in series with energy accumulator means  38 ,  40 . Thus, it is provided in particular that when torque converter lockup clutch  14  is closed, torque can be transferred from first energy accumulator means  38  through first component  46  to second energy accumulator means  40 . First component  46  can also be designated as intermediary component  46 , which is done in the following. 
     In the embodiments shown in  FIGS. 1-3 , it is provided that turbine dish  26  is connected to intermediary component  46 , so that a load, in particular torque and/or a force can be transferred from turbine dish  26  to intermediary component  46 . 
     Between turbine dish  26  and intermediary component  46 , or in the load flow, in particular, in the torque flow, or in the force flow between turbine dish  26  and intermediary component  46 , a driver component is provided. It can also be provided that extension  32  also forms intermediary component  46  and/or driver component  50 , or takes over their function. It is furthermore provided that along load transfer path  48 , through which the load is transferable from turbine dish  26  to intermediary component  46 , at least one connection means  52 ,  56  or  54  is provided. Such a connection means  52 ,  56 , or  54  can, e.g., be a plug-in connection, or a rivet connection or bolt connection  56 , as shown in  FIGS. 1-3 , or weld  52 , as shown in  FIGS. 1-3 , or other similar means. It is appreciated that at the location, where weld  52  is provided, a rivet or bolt connection is drawn additionally in order to show an alternative embodiment. This is also intended to emphasize that the connection means can also be configured differently, or can be combined differently. By means of the respective connection means  52 ,  54 , and, or  56 , respective, adjoining components of load transfer path  48  are coupled amongst each other, through which the load can be transferred from turbine dish  26  to intermediary component  46 . 
     It is provided that all connection means  52 ,  54 , and  56 , by which components like extension  32  and driver component  50 , or driver component  50  and intermediary component  46 , are connected along load transfer path  48  between turbine dish  26  and intermediary component  46 , are offset from wall section  30  of turbine dish  26 , directly abutting to wall interior  28 . 
     Second component  60  and third component  62  are connected in series with first energy accumulator means  38 , second energy accumulator means  40 , and intermediary component  46 , provided between first and second energy accumulator means  38  and  40 , respectively. Second component  60  forms an input component of first energy accumulator means  38  and third component  62  forms an output component of second energy accumulator means  40 . A load or torque induced by second component  60  into first energy accumulator means  38  can thus be transferred to third component  62  at the output of first energy accumulator means  38  through intermediary component  46  and second energy accumulator means  40 . 
     Third component  62  engages hub  64 , forming a non-rotatable connection wherein hub  64 , in turn, is non-rotatably coupled to output shaft  66  of torque converter device  1 , which is, for example, a transmission input shaft of a motor vehicle transmission. Turbine dish  26  is radially supported at hub  64  by means of support section  68 . Support section  68 , which is radially supported in particular at hub  64 , is substantially sleeve-shaped. 
     It is provided that the radial support of turbine dish  26  by means of support section  68  is performed, so that support forces acting upon turbine dish  26  are not conducted through first energy accumulator means  38 , or through second energy accumulator means  40  from support section  68  to turbine dish  26 . Support section  68  is rotatable relative to hub  64 . It can be provided that a straight bearing, a straight bearing bushing, a roller bearing, or the like are provided for radial support between hub  64  and support section  68 . Furthermore, respective bearings can be provided for axial support. The connection discussed supra between turbine dish  26  and intermediary component  46  is configured so that torque, which is transferable from turbine dish  26  to intermediary component  46 , can be transferred by turbine dish  26  to intermediary component  46 , without one of first or second energy accumulator means  38  and  40 , respectively, being provided along load transfer path  48 . The torque transfer from turbine dish  26  to intermediary component  46  through load transfer path  48  can thus be effectuated by means of a substantially rigid connection. 
     In the embodiments shown in  FIGS. 1-3  two respective connection means are provided along load transfer path  48  between turbine dish  26  and intermediary component  46 , thus first connection means  52  or  54  and second connection means  56 . First connection means  52  or  54  non-rotatably connects extension  32  to driver component  50 , and second connection means  56  non-rotatably connects driver component  50  to intermediary component  46 . It is appreciated that, with reference to the circumferential direction of rotation axis  36 , several distributed first connection means  52  or second connection means  56  can be provided, or are preferably provided. 
     In the embodiments shown in  FIGS. 1-3  sleeve-shaped support portion  68  is an inner portion of driver component  50  with reference to the radial direction of rotation axis  36 . 
     Converter lockup clutch  14  is configured in the embodiments shown in  FIGS. 1-3  as a respective multi-disc clutch and comprises first disk carrier  72 , by which first disks  74  are non-rotatably received and second disk carrier  76  by which second disks  78  are non-rotatably received . When multi-disc clutch  14  is open, first disk carrier  72  is movable relative to second disk carrier  76 , and thus so that first disk carrier  72  can be rotated relative to second disk carrier  76 . Second multi-disc carrier  76  is disposed here with reference to the radial direction of axis  36  radially within first disk carrier  72 , however, also the opposite can be the case. First disk carrier  72  is attached to converter housing  16 . Multi-disc clutch  14  comprises a press component for actuation, which is piston  80  in this case, which is disposed axially movable and can be loaded for actuating the multi-disc clutch  14 , for example, hydraulically. Piston  80  is mounted in a rigid or non-rotatable manner to second disk carrier  76 , which can be effectuated, for example, by a weld. First disks  74  and second disks  78  alternate in longitudinal direction of rotation axis  36 . When loading the multi-disc packet  79 , formed by first disk  74  and second disk  78  by piston  80 , disk packet  79  is supported at the side of disk packet  79  opposed to piston  80  at a section of the inside of converter housing  16 . Between adjacent disks  74  and  78  and on both ends of disk packet  79 , friction liners  81  are provided, which are, for example, held at disk  74  and/or  78 . Friction liners  81 , which are provided at the ends of disk packet  79 , can be held on the one side and/or the other side, and also on the inside of converter housing  16  or at piston  80 . 
     In the embodiments shown in  FIGS. 1 and 2 , piston  80  is configured integrally with the second component, thus the input component of first energy accumulator means  38 . In the embodiment shown in  FIG. 3 , piston  80  is non-rotatably connected or in a solid manner to second component  60  or to the input component of first energy accumulator means  38 , wherein the rigid connection is performed here, for example, by a weld. As a matter of principle, the non-rotatable connection can also be performed in another manner. In an alternative configuration of the embodiments shown in  FIGS. 1 and 2 , the piston and input component  60  of first energy accumulator means  38  can also be configured as separate components, which are connected amongst one another, for example, by a weld or by a rivet or bolt in a rigid or non-rotatable manner. In the embodiment shown in  FIG. 3 , in order to create a solid or non-rotatable connection instead of the weld, another suitable connection between piston  80  and input component  60  can also be provided, for example, a bolt or a rivet connection, or a plug-in connection, or, alternatively, piston  80  can be integrally manufactured in one piece with input component  60 . 
     The press component or piston  80  or second component  60 , and/or first component, or intermediary component  46  and/or third component  62  and/or drive component  50  are preferably formed by a plate. In particular, second component  60 , first component  46 , and third component  62  each comprises a flange. 
     In the embodiment shown in  FIG. 2 , the mass and/or the mass moment of inertia and/or the plate thickness of driver component  50  is greater than the mass moment of inertia, or the mass, or the plate thickness of piston  80 , or of input component  60  of first energy accumulator means  38 , or of the unit made of components  60  and  80 . 
     For first energy accumulators  42 , a type of housing  82  is formed respectively, which extends with reference to the radial direction of rotation axis  36  and with respect to the axial direction of rotation axis  36  at least partially on both sides axially and radially outside about the respective first energy accumulator  42 . In the embodiments shown in  FIGS. 1-3 , housing  82  is disposed at driver component  50 . In most applications, the non-rotatable arrangement at driver component  50  is advantageous from a vibration point of view, since more mass or mass moment of inertia is transferred to the secondary side of first energy accumulator means  38 . 
     In the embodiment shown in  FIG. 3 , first energy accumulators  42  can be respectively supported at housing  82  by means  84  comprising roller elements like balls or rollers, which can also be designated as roller shoe, and which is used for friction reduction. In the embodiments shown in  FIGS. 1 and 2 , slider dish or slider shoe  94  is provided for friction reduction, through which first energy accumulators  42  can be supported at housing  82 . 
     Furthermore, second rotation angle limiter means  92  is provided in the embodiments shown in  FIGS. 1-3  for second energy accumulator means  40 , by which the maximum rotation angle, or relative rotation angle of second energy accumulator  40 , or of the input component of second energy accumulator means  40  is limited relative to the output component of second energy accumulator means  40 . This is performed so that the maximum rotation angle of second energy accumulator means  40  is limited by second rotation angle limiter means  92 , so that it is avoided that second energy accumulators  44 , which are springs in particular, go into blockage under a respectively high torque load. 
     Second rotation angle limiter means  92  is configured, as shown in  FIGS. 1-3 , so that driver component  50  and intermediary component  46  are non-rotatably connected by a bolt, which is, in particular, a component of connection means  56 , wherein the bolt extends through a slotted hole, which is provided in the output component of second energy accumulator means  40 , or in third component  62 . Also, a first rotation angle limiter means for first energy accumulator means  38  can be provided, which is not shown in the figures, by which the maximum rotation angle of first energy accumulator means  38  is limited, so that a blockage loading of first energy accumulators  42 , which are, in particular, respectively configured as springs, is avoided. In particular when, which advantageously is the case, second energy accumulators  44  are straight (compression) springs and first energy accumulators  42  are arc springs, it can be provided, that, as shown in  FIGS. 1-3 , only a second rotation angle limiter means is provided for second energy accumulator means  40 , since in such embodiments, in case of a blockage loading, the risk of damages is reduced by arc springs, compared to straight springs, and an additional first rotation angle limiter means would reduce the number of components, or the manufacturing cost. 
     In a particularly advantageous configuration, it is provided in the embodiments shown in  FIGS. 1-3 , that the rotation angle of first energy accumulator means  38  is limited to a maximum first rotation angle, and the rotation angle of the second energy accumulator means is limited to a maximum second rotation angle, wherein first energy accumulator means  38  reaches its maximum first rotation angle, when a first threshold torque is applied to first energy accumulator means  38 , and wherein second energy accumulator means  40  reaches its maximum second rotation angle, when a second threshold torque is applied to second energy accumulator means  40 , wherein the first threshold torque is smaller than the second threshold torque. This can be accomplished in particular by a respective matching of energy accumulator means  38  and  40 , or of energy accumulators  42  and  44  of energy accumulator means  38  and  40 , possibly, or in particular also by the first and/or second rotation angle limiter means. 
     It can be provided that first energy accumulators  42  go in to blockage at the first threshold torque, so that first energy accumulator means  38  reaches its maximum first rotation angle and that it is effectuated by a second rotation angle limiter means for second energy accumulator means  40  that second energy accumulator means  40  reaches its maximum second rotation angle at a second threshold torque, wherein the maximum second rotation angle is reached, when the second rotation angle limiter means reaches a stop position. This way, in particular a good setting for partial load operation can be achieved. 
     It is appreciated that the rotation angle of first energy accumulator means  38  or of second energy accumulator means  40 , and this applies analogously for the maximum first or the maximum second rotation angle, is the relative rotation angle with reference to the circumferential direction of rotation axis  36  of torsion vibration damper  10 , which is provided relative to the unloaded resting position between components directly adjoining the respective energy accumulator means  38  or  40  on the input side and on the output side for a torque transfer. The rotation angle, which is limited in particular in the manner by the respective maximum first or second rotation angle, can change in particular by energy accumulators  42  and/or  44  of the respective energy accumulator means  38  and  40  absorbing energy or releasing stored energy. 
     In the embodiments shown in  FIGS. 1-3 , piston  80 , the second component, or input component  60  of first energy accumulator means  38  forms several ears  86  distributed about the circumference, each of them comprising non-free end  88  and free end  90 , and which are provided for the front face side, input side loading of a respective first energy accumulator  42 . Non-free end  88  is thus disposed radially within free end  90  of respective ear  86  with reference to the radial direction of rotation axis  36 . By this, it is meant that the non-free end of the ear is disposed radially closer to the axis of rotation than the free end of the ear, as illustrated in  FIGS. 1 through 3 . In addition, as shown in  FIGS. 1 through 3 , ear  86  is illustrated as an elongated structure extending from a base structure (e.g., input component  60 ). By free end, it is meant a portion of the ear which is distal to the base structure. By non-free end, it is meant a portion of the ear which is proximate from the base structure. 
     The configuration of ears  86  of input component  60  of first energy accumulator means  38  and its respective disposition relative to the respective assigned first energy accumulators  42  and its respective interaction with the respective front face  150  of each respective first energy accumulator  42 , is substantially constant and is, therefore, described infra with reference to ear  86  and with reference to a respective first energy accumulator  42 , which can be loaded by ear  86 , or with reference to its respective front face  150 , which can be loaded by ear  86 . 
     Straight connection line  152 , extending through free end  90  and through non-free end  88  of ear  86 , in particular, respectively in a centric manner, encloses an angle α with straight line  154 , extending in a radial direction to rotation axis  36  of torsion vibration damper  10 , wherein angle α is less than 70°, or less than 60°, or less than 50°, or less than 40°, or less than 30°, and is approximately 20° in this case, which, in particular, applies to a respective projection into a projection plane, which is established by front face  150  of first energy accumulator  42 , which can be loaded by ear  86 . 
     The projection of ear  86  into the projection plane, which is established by front face  150  of first energy accumulator  42 , which can be loaded by ear  86 , intersects respectively once with outer circumference  156  of front face  150  projected into the projection plane, as shown in  FIGS. 1-3 , so that projected outer circumference  156  and projected ear  86  form intersection lines in the projection plane, so that first intersection line  160  is formed in the projection plane by ear  86 , viewed from its respective non-free end  88  along its extension from non-free end  88  to its free end  90 , intersecting along its extension with projected outer circumference  156  for the first time, wherein first intersection line  160  is disposed in the projection plane in a radially inner portion in its entirety with respect to the radial direction of rotation axis  36  of torsion vibration damper  10  of the respective first energy accumulator  42 . 
     However, it can also be provided in an alternative embodiment, that the projected ear  86  intersects the projected outer circumference  156  of front face  150  several times, so that projected outer circumference  156  and projected ear  86  form several intersection lines in the projection plane, wherein first intersection line  160  is formed by ear  86 , viewed from its respective non-free end  88  along its extension from non-free end  88  to its respective free end  90 , intersecting projected exterior circumference  156  for the first time, wherein first intersection line  160  is disposed in its projection plane in a radially inner portion of first energy accumulator  42  with respect to the radial direction of rotation axis  36  of torsion vibration damper  10 , and, thus, completely. For example, the embodiments shown in  FIGS. 1-3  in the latter sense can be modified, so that ear  86  in the portion of free end  90  with reference to the radial direction of rotation axis  36  is extended on the radial outside barely beyond outer circumference  156  of front face  150 , so that projected ear  86  and projected outer circumference  156  of front face  150  form two intersection lines in the projection plane, and wherein first intersection line  160  is disposed in a projection plane with reference to the radial direction of rotation axis  36  of torsion vibration damper  10  in a radially inward portion of first energy accumulator  42 . 
     According to the embodiments shown in  FIGS. 1-3 , first intersection line  160 , which is illustrated as a projection into the projection plane when viewed in a circumferential direction with respect to front face  150 , and which can be loaded by ear  86  of first energy accumulator  42 , is disposed with reference to radial direction  36  of torsion vibration damper  10  in a radially inward portion of first energy accumulator  42 , so that first intersection line  160  is disposed in the projection plane with reference to the radial direction of rotation axis  36  of torsion vibration damper  10  radially within center force effect line  162  of energy accumulator  42 , wherein force effect line  162  is illustrated as a point, and where force effect line  162  intersects the projection plane. 
     Thus, it is provided that first intersection line  160  is disposed within a portion, which extends symmetrically about radial straight line  154  with reference to the radial direction of rotation axis  36  of torsion vibration damper  10 , wherein straight line  154  extends through central force effect line  162 , or through the point formed by it in the projection plane, wherein the portion, viewed in a circumferential direction with respect to front face  150  of first energy accumulator  42 , covers less than 140°, preferably less than 120°, preferably less than 100°, and, as shown in  FIGS. 1-3 , as indicated by the angle β, covers approximately 90°. 
     Ear  86  is configured straight in portion  164  adjoining to free end  90 . This is configured so that ear  86  in portion  164  extends substantially in radial direction with reference to the radial direction of rotation axis  36 . 
     It can be provided that first energy accumulator  42  is configured as an arc spring or as a coil spring and that its respective front face  150 , which can be loaded by ear  86 , is formed by an end side or face side spring winding. In particular, in such an embodiment, it can be provided that ear  86  can load front face  150  at two locations offset in a circumferential direction with respect to front face  150 , which are offset from one another in the circumferential direction by at least 100°, preferably by at least 110°, and most preferably by at least 120°. This offset amounts to almost 130° according to  FIGS. 1-3 . 
     It can be provided, that caps are applied on the end sides to first energy accumulators  42 , so that the respective ear  86  loads the respective front face of first energy accumulator  42  by means of such a cap. 
     As stated supra, according to DE 103 58 901 A1 the actuation elements extend from the radial outside, or from the above, or from the side to the respective front face of the respective energy accumulator of the outer energy accumulator means. Accordingly, it can be said that according to the embodiments of the invention, the control elements or ears  86  extend from the radial inside or from below to the respective front face of the respective first energy accumulator  42  of the outer or first energy accumulator means  38 , or from below, or from the radial inside into the respective first energy accumulator  42  of the outer or first energy accumulator means  38 . 
     Thus, it is seen that the objects of the present invention are efficiently obtained, although modifications and changes to the invention should be readily apparent to those having ordinary skill in the art, which modifications are intended to be within the spirit and scope of the invention as claimed. It also is understood that the foregoing description is illustrative of the present invention and should not be considered as limiting. Therefore, other embodiments of the present invention are possible without departing from the spirit and scope of the present invention.
