     FIELD OF THE INVENTION 
       [0002]    The invention relates to a hydrodynamic torque converter device for a motor vehicle drive train, comprising a torsion vibration damper. 
       BACKGROUND OF THE INVENTION 
       [0003]    A hydrodynamic torque converter device comprising a torsion vibration damper and a converter torus formed by a pump shell, a turbine shell and a stator shell, and which comprises a converter lockup clutch, is shown in  FIG. 2  of German Patent No. DE 199 20 542 A1. According to this known embodiment, the torsion vibration damper comprises a first energy accumulator means, which comprises several first energy accumulators respectively configured as arc springs, and a second energy accumulator means, which is disposed, with reference to the radial direction of the rotation axis of the torsion vibration damper, radially within the first energy accumulator means, and which comprises several second energy accumulators. The first energy accumulators are thus inserted into wear protection shells. 
         [0004]    German Patent No. DE 102 09 838 A1 discloses a rotation- or torsion vibration damper with exactly one energy accumulator means, which comprises at least one first energy accumulator formed by a coil spring. With reference to the radial direction of the rotation axis of the torsion vibration damper, a wall thus extends on the radial exterior of the at least one first energy accumulator, at which the at least one first energy accumulator can be radially supported. In order to avoid particularly high friction between the at least one first energy accumulator, slider shoes are used, which are supported towards the radial exterior at the wall, and which are slid onto at least one radially exterior portion of at least one winding of the at least one energy accumulator. 
       BRIEF SUMMARY OF THE INVENTION 
       [0005]    Broadly, the present invention is a hydrodynamic torque converter device for a motor vehicle drive train, wherein the torque converter device comprises a torsion vibration damper, a converter torus formed a pump shell, a turbine shell and a stator shell and comprises a converter lockup clutch. The torsion vibration damper comprises a first energy accumulator means. The first energy accumulator means comprises one or more first energy accumulators, or it is formed by the energy accumulator(s). One or more first walls is provided for the radial support of the at least one first energy accumulator. For low friction support of the at least one first energy accumulator at the at least one first wall, at least one roller element means is provided. The roller element means comprises at least one, but preferably several roller elements. The roller elements are balls, in a preferred embodiment. The roller element means is disposed between the at least one first energy accumulator and the at least one first wall. 
         [0006]    It should be appreciated that a device designated herein as “converter torus” is partially designated as “hydrodynamic torque converter”. The term “hydrodynamic torque converter” is, however, partially used in prior publications also for devices comprising a torsion vibration damper, a converter lockup clutch and a means formed by a pump shell, a turbine shell and a stator shell, or a converter torus, according to the language of the present disclosure. Hereinafter, the terms “hydrodynamic torque converter device” and “converter torus” are used in the present disclosure. 
         [0007]    Preferably, several roller element means can be provided, wherein the roller elements preferably are balls or rollers. Subsequently, a roller element means is described for simplification purposes, wherein, in preferred embodiments in which several roller elements are provided, these can respectively be configured as it is described for the roller element means. The roller element can be designated as roller shoe, in particular. 
         [0008]    The roller element means, in a preferred embodiment, comprises a roller element carrier and several roller elements, which are received or supported by the roller element carrier. 
         [0009]    The first wall is non-rotatably coupled, in a preferred embodiment, to an output component of the first energy accumulator means, or it is formed at or by the output component. It can also be provided that the first wall is non-rotatably coupled to an input component of the first energy accumulator means, or formed at or by the input component. 
         [0010]    It is provided, in particular, that the torsion vibration damper is rotatable about a rotation axis. Non-rotatable connections or couplings of components, which are mentioned in the context of the present disclosure, are non-rotatably connected or coupled with reference to a rotation about the axis of rotation. 
         [0011]    In a preferred embodiment, the first wall is substantially closed circumferentially with reference to the circumferential direction of the rotation axis of the torsion vibration damper. The first wall can, e.g., be cylindrical or annular. The first wall forms on its surface, which is disposed radially inward with reference to the radial direction of the rotation axis of the torsion vibration damper, a support portion for the roller element means. Between the first wall and the roller element means or between the roller elements of the roller element means, a dish can be provided, through which the roller elements of the roller element means are supported at the first wall. 
         [0012]    In a preferred embodiment, the torsion vibration damper comprises a second energy accumulator means in addition to the first energy accumulator means, wherein the second energy accumulator means comprises one or several second energy accumulators. Thus, it can be provided that the converter lockup clutch, the first energy accumulator means, and the second energy accumulator means are connected in series. This can also be provided so that, within the serial connection, the first energy accumulator means is disposed between the converter lockup clutch and the second energy accumulator means. In a preferred embodiment, an intermediary component is provided, which is also connected in series with the first and the second energy accumulator means within the series connection between the first and the second energy accumulator means, wherein the intermediary component is, e.g., an input component of the second energy accumulator means and/or an output component of the first energy accumulator means, or non-rotatably coupled to the input component and the output component, wherein one or the outer turbine dish of the turbine or of the turbine shell is non-rotatably coupled to the intermediary component. 
         [0013]    The invention may further include a torsion vibration damper particularly configured for a motor vehicle drive train. The torsion vibration damper can be improved, as it is described in the context with the torsion vibration damper of the hydrodynamic torque converter device according to the invention. 
         [0014]    It is the object of the invention to provide a hydrodynamic torque converter device comprising a torsion vibration damper for a motor vehicle drive train, and a torsion vibration damper, which have good operating characteristics. 
         [0015]    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.

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. 
         [0023]    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. 
         [0024]    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. 
         [0025]      FIGS. 1-5  show different exemplary embodiments of hydrodynamic torque converter device  1  of the present invention, each comprising exemplary torsion vibration dampers  10 . Hydrodynamic torque converter devices  1  shown therein can each be integrated into motor vehicle drive train  2 , or can be components of motor vehicle drive train  2 . 
         [0026]    As shown in  FIGS. 1-5 , hydrodynamic torque converter device  1  further comprises converter torus  18  formed by pump shell  12 , turbine shell  14  and stator shell  16  and also comprises converter lockup clutch  20 . 
         [0027]    Torsion vibration damper  10 , converter torus  18  and converter lockup clutch  20  are received in converter housing  22 . Converter housing  22  is substantially non-rotatably connected to drive shaft  24 , which is, e.g., the crank shaft or engine output shaft of a combustion engine. Torsion vibration damper  10  is rotatable about rotation axis  26 . 
         [0028]    Torsion vibration damper  10  comprises first energy accumulator means  28 . In the embodiments shown in  FIGS. 1 and 2 , torsion vibration damper  10  only comprises one energy accumulator means  28 , thus first energy accumulator means  28 . In the embodiments shown in  FIGS. 3 and 4 , torsion vibration damper  10  comprises second energy accumulator means  30  in addition to first energy accumulator means  28 . As shown in  FIGS. 3 and 4 , first energy accumulator means  28  is disposed therein with reference to the radial direction of rotation axis  26  radially outside of second energy accumulator means  30 . Energy accumulator means  28  and  30  can be alternatively disposed, e.g., at the same radial elevation or substantially at the same elevation, which is not shown. Second energy accumulator means  30  is connected in series with first energy accumulator means  28 . 
         [0029]    As illustrated in  FIGS. 1-5 , torque converter device  1  comprises input component  32  for torsion vibration damper  10  and output component  34  for torsion vibration damper  10 . In the embodiments shown in  FIGS. 1-5 , input component  32  for torsion vibration damper  10  forms input component  32  for first energy accumulator means  28 . In the embodiments shown in  FIGS. 1 and 2 , output component  34  for torsion vibration damper  10  forms output component  34  for first energy accumulator means  28 , and in the embodiments shown in  FIGS. 3-5 , output component  34  for torsion vibration damper  10  forms output component  34  for second energy accumulator means  30 . In the embodiments shown in  FIGS. 4 and 5 , two respective output components  34  for second energy accumulator means  30 , or two output components  34  for torsion vibration damper  10 , are provided, which are non-rotatably coupled amongst one another and connected in parallel with each other. In the embodiments shown in  FIGS. 1-5 , the torsion vibration damper can transfer a torque from its input component  32  to its output component(s)  34 . 
         [0030]    In the embodiments shown in  FIGS. 1-5 , output component(s)  34  of torsion vibration damper  10  engage(s) hub  36 , forming a non-rotatable connection, wherein hub  36  is, in turn, connected to output shaft  38  of torque converter device  1 , which, in turn, is a transmission input shaft of a motor vehicle transmission. It can alternatively be provided that hub  36 , non-rotatably coupled to shaft  38 , is integrally formed with output component(s)  34  or connected by welding or the like. 
         [0031]    Turbine shell  14  comprises outer turbine dish  40 . Outer turbine dish  40  comprises extension  42 . Extension  42  comprises straight or annular portion  44 . Straight or annular portion  44  of extension  42  can, e.g., be configured so that it is substantially straight in radial direction of rotation axis  26  of torsion vibration damper  10 , and that it is disposed as an annular section in a plane perpendicular to rotation axis  26 , or that it defines the plane. In the portion of extension  42 , or of straight or annular section  44  of extension  42 , a non-rotatable connection is provided by a connection means, as illustrated in  FIGS. 1-5  as rivet or bolt  46  and/or weld  48 , to one or at least one subsequent or adjoining component in the torque flow (see, driver component  50  in  FIG. 1 , driver component  52  in  FIG. 2 , driver component  54  in  FIG. 3 , driver component  56  in  FIG. 4 , and driver component  58  in  FIG. 5 ). Thus, it is facilitated that the turbine or turbine shell  14  or outer turbine dish  40  can be easily non-rotatably connected to subsequent components in the torque flow. 
         [0032]    Outer turbine dish  40  is radially supported at hub  36 , in particular, by sleeve-shaped support section  60 . Support section  60  is non-rotatably connected to outer turbine dish  40 . Support section  60  or outer turbine dish  40  is rotatable relative to hub  36 . It can be provided that, between hub  36  and support section  60 , a straight bearing or a straight bearing bushing or a roller bearing or similar are provided for radial support. Furthermore, respective bearings can be provided for axial support. 
         [0033]    In the embodiments shown in  FIGS. 3-5 , in which torque converter device  1  comprises two energy accumulator means  28  and  30 , intermediary component  62  is provided between energy accumulator means  28  and  30 , wherein intermediary component  62  is connected in series with energy accumulator means  28  and  30 . Furthermore, output component  64  of first energy accumulator means  28  and input component  66  of second energy accumulator means  30  are provided in the embodiments shown in  FIGS. 3-5 . Intermediary component  62  can, e.g., be output component  64  of first energy accumulator means  28 , as shown in  FIGS. 4 and 5 , or it can be input component  66  of second energy accumulator means  30 , as shown in  FIGS. 3-5 , or it can be a component, which is different from output component  64  and input component  66 . It can also be provided that output component  64  of first energy accumulator means  28  and input component  66  of second energy accumulator means  30  are formed by the same component, which then is intermediary component  62 , as shown in  FIG. 3 . Output component  64  of first energy accumulator means  28  and input component  66  of second energy accumulator means  30 , however, can also be formed by different components, as shown in  FIGS. 4 and 5 . In the embodiments shown in  FIGS. 3-5 , e.g., when converter lockup clutch  20  is closed, a torque can thus be transferred from input component  32  of first energy accumulator means  28  through energy accumulator means  28  to intermediary component  62  and from intermediary component  62 , through second energy accumulator means  30  to output component  34  of second energy accumulator means  30 . 
         [0034]    With respect to the embodiments shown in  FIGS. 3-5 , first energy accumulator means  28  and/or second energy accumulator means  30  are spring means, in particular. 
         [0035]    In the embodiments shown in  FIGS. 1-5 , first energy accumulator means  28  comprises a plurality of first energy accumulators  68  arranged in a circumferential direction extending about rotation axis  26  and disposed at a distance from one another, which are coil springs or arc springs, in particular. It can be provided that several first energy accumulators  68  are configured identically. It can also be provided that differently configured first energy accumulators  68  are provided. It can furthermore be provided that all first energy accumulators  68 , with reference to the circumferential direction of rotation axis  26 , are offset from one another. However, it can also be provided that several first energy accumulators  68  are spaced at a distance from one another in circumferential direction and receive at least one additional first energy accumulator  68  in their interior. 
         [0036]    In the embodiments shown in  FIGS. 3-5 , second energy accumulator means  30  comprises a plurality of second energy accumulators  70 , respectively provided as a coil spring, straight spring or straight compression spring. Thus, in a preferred embodiment, all or several second energy accumulators  70  are disposed with reference to the circumferential direction of rotation axis  26  offset at a distance from one another. It can be provided that second energy accumulators  70  are configured respectively identically. Different second energy accumulators  70 , however, can also be configured differently. It can be provided that, with reference to the circumferential direction of rotation axis  26 , all second energy accumulators  70  are offset from one another. However, it can also be provided, e.g., that several second energy accumulators  70  are offset in circumferential direction from one another and receive at least one additional second energy accumulator  70  in their interior. 
         [0037]    Converter lockup clutch  20  is configured as a respective multi-disk clutch in the embodiments shown in  FIGS. 1-5 , and comprises first disk carrier  72 , by which first disks  74  are non-rotatably received, and comprises second disk carrier  76 , by which second disks  78  are non-rotatably received. When multi-disk clutch  20  is open, first disk carrier  72  is movable relative to second disk carrier  76 , so that first disk carrier  72  can be rotated relative to second disk carrier  76 . Second disk carrier  76  is disposed radially within first disk carrier  72  with reference to the radial direction of axis  26 , which, however, can also be arranged the other way around. First disk carrier  72  is attached to converter housing  22 . For actuation, multi-disk clutch  20  comprises piston  80 , which is disposed axially movable, and which can be loaded, e.g., hydraulically for actuating multi-disk clutch  20 . Piston  80  is non-rotatably attached or connected to second disk carrier  76 , which can be effectuated, e.g., by a welded connection. First disk  74  and second disk  78  alternate in longitudinal direction of the rotation axis. When loading disk packet  82 , formed by first disk  74  and by second disks  78  by means of piston  80 , disk packet  82  is supported on the side of disk packet  82  opposite to piston  80  at a section of inner side  84  of converter housing  22 . Between adjacent disks  74  and  78 , and at both ends of disk packet  82 , friction liners  86  are provided, which are, e.g., supported at disks  74  and/or  78 . Friction liners  86 , which are provided at the end sides of disk packet  82 , can be held on the one side and/or the other side, or at the inside  84  of converter housing  22 , or at piston  80 . 
         [0038]    Piston  80  is integrally connected to input component  32  of first energy accumulator means  28 , or non-rotatably connected to input component  32 . 
         [0039]    Torsion vibration damper  10  of torque converter device  1 , in the embodiment shown in  FIG. 2 , comprises only one energy accumulator means, namely, first energy accumulator means  28 , wherein first energy accumulators  68  of first energy accumulator means  28  are arc springs. This is also the case in the embodiment shown in  FIG. 1 . However, in this embodiment, as opposed to that which is shown in  FIG. 2 , first energy accumulator means  28 , with reference to the radial direction of rotation axis  26 , is disposed substantially further on the radial inside. With reference to the radial distance between axis  26  and the radially exterior section of the enveloping surface of converter housing  22 , the axes or the center force effect lines of first energy accumulators or arc springs  68  are disposed in the two inner thirds of the distance, while in the embodiment shown in  FIG. 2 , the center axes or force effect lines are substantially positioned in the radially exterior third. The embodiment shown in  FIG. 1  can also be designated as “small radius damper”, which comprises arc springs and which is configured in a turbine torsion damper configuration. The configuration shown in  FIG. 2  can also be designated as turbine torsion damper (TTD) comprising arc springs. In the embodiments shown in  FIGS. 1 and 2 , outer turbine shell  40  is non-rotatably connected to input component  32  of first energy accumulator means  28 . 
         [0040]    In the embodiments shown in  FIGS. 4 and 5 , in which torsion vibration damper  10  of torque converter device  1  comprises first energy accumulator means  28  and second energy accumulator means  30 , outer turbine dish  40  is non-rotatably connected to input component  32  of first energy accumulator means  28 . 
         [0041]    In the embodiment shown in  FIG. 3 , as opposed to those which are shown in  FIGS. 4 and 5 , outer turbine dish  40  is non-rotatably connected to intermediary component  62  or to output component  64  of first energy accumulator means  28 , or to input component  66  of second energy accumulator means  30 . 
         [0042]    Input component  32  of first energy accumulator means  28  forms respective support portions in the embodiments shown in  FIGS. 1-5 , by means of which first energy accumulators  68  can be supported or loaded at their first ends. In the embodiments shown in  FIGS. 1 and 2 , output component  34  of first energy accumulator means  28  forms support portions, by means of which respective first energy accumulators  68  can be supported or loaded at their second ends, which are the ends respectively facing away from the respective first ends. In the embodiments shown in  FIGS. 3-5 , output component  64  of first energy accumulator means  28  forms support portions, by means of which respective first energy accumulators  68  can be supported or loaded at their second ends, which are the ends facing away from the respective first ends. Furthermore, in the embodiments shown in  FIGS. 3-5 , the respective input component  66  of second energy accumulator means  30  forms support portions, by means of which second energy accumulators  70  can be supported or loaded at their first ends. Furthermore, in the embodiments shown in  FIGS. 3-5 , the respective output component  34  of second energy accumulator means  30  forms support portions, by means of which second accumulators  70  can be supported or loaded at their second ends, which are the ends respectively facing away from the first end. 
         [0043]    In the embodiments shown in  FIGS. 1 and 2 , piston  80  or input component  32  of first energy accumulator means  28  and/or output component  34  of first energy accumulator means  28  is a flange or plate, respectively. In the embodiments shown in  FIGS. 3-5 , piston  80  or input component  32  of first energy accumulator means  28 , or intermediary component  62 , or intermediary component  54  or driver component  54 ,  56 , or  58 , or output component  34  of second energy accumulator means  30 , is a flange or plate, respectively. 
         [0044]    In the embodiment shown in  FIG. 3 , output component  64  of first energy accumulator means  28  is formed by driver component  54 . Driver component  54  is disposed such that outer turbine dish  40  or its extension  42  non-rotatably connects to intermediary component  62 , so that it is facilitated that a torque can be transferred from outer turbine dish  40  through driver component  54  to intermediary component  62 . Additionally, in this particular embodiment, it can also be provided, that extension  42  also forms intermediary component  62  and/or driver component  54 , or performs their functions. It can also be provided that driver component  54  forms intermediary component  62 , which is connected in series in the torque flow between energy accumulator means  28  and  30 . It can also be provided in this embodiment, which, however, is not shown in the figure, that the mass moment inertia and/or the plate thickness of driver component  54  is greater than the mass moment of inertia or the plate thickness of piston  80 , or of input component  32  of first energy accumulator means  28 , or of the unit made from components  32  and  80 . 
         [0045]    In the embodiments shown in  FIGS. 3-5 , input component  32  of first energy accumulator means  28  can be rotated relative to output component  64  of first energy accumulator means  28 , and thus, in particular, about the axis  26 , wherein the relative rotational angle between input component  62  and output component  64  is limited to a maximum first relative rotation angle. Furthermore, input component  66  of second energy accumulator means  30  can be rotated relative to output component  34  of second energy accumulator means  30 , and thus, in particular, about rotation axis  26 , wherein the relative rotation angle between input component  66  and output component  34  is limited to a maximum second rotation angle. 
         [0046]    Torsion vibration damper  10  is respectively configured according to the embodiments shown in  FIGS. 3-5 , so that input component  32  of first energy accumulator means  28  is rotated relative to output component  64  of first energy accumulator means  28  according to the maximum relative rotation angle, when a torque is supplied to first energy accumulator means  28 , which is greater than or equal to a first threshold torque, and so that input component  66  of second energy accumulator means  30  is rotated relative to output component  34  of second energy accumulator means  30  according to the maximum second relative rotation angle, when a torque is applied to second energy accumulator means  30 , which is greater than or equal to a second threshold torque. Thus, it is provided that the first threshold torque is less than the second threshold torque. It can, e.g., be provided that the second threshold torque is greater than 1.5 times, preferably greater than 2 times, preferably greater than 3 times, and preferably greater than 4 times the first threshold torque. The second threshold torque can be greater or equal or less than the maximum engine torque of a combustion engine of the drive train, in which the torque converter device is installed. 
         [0047]    In the embodiment shown in  FIG. 3 , and this can be accordingly provided in the embodiments shown in  FIGS. 4 and 5 , it is provided that first, or at least several, first energy accumulators  68  of first energy accumulator means  28  go into blockage, when a torque is supplied to first energy accumulator means  28 , which corresponds to the first threshold torque, and that second relative rotation angle limiter means  88  is provided, by which the second relative rotation angle of input component  66  of second energy accumulator means  30  is limited relative to output component  34  of second energy accumulator means  30  to the maximum second relative rotation angle. Thus, it is provided that the second relative rotation angle is limited by second relative rotation angle limiter means  88 , so that it is avoided that second energy accumulators  70 , which are springs, go into blockage under a correspondingly high torque loading. 
         [0048]    Second relative rotation angle limiter device  88  is, as illustrated in  FIG. 3 , e.g., configured so that output component  64  or driver component  54  and intermediary component  62  are non-rotatably connected through bolt  90 , wherein bolt  90  extends through a slotted hole, or into a groove, which is provided in output component  34  of second energy accumulator means  30 . When a torque corresponding to the second threshold torque is applied to second energy accumulator means  30 , second relative rotation angle limiter means  88  reaches a stop position, by which it is avoided, that the second relative rotation angle is increased further. The relative rotation angle, which is given when reaching the stop position between input component  66  and second accumulator means  30  and output component  34  of second energy accumulator means  30 , is the maximum second relative rotation angle. While not shown in the figures, it is appreciated that, in the embodiments shown in  FIGS. 4 and 5 , second relative rotation angle limiter means  88  can be provided, there, e.g., two output components  34  of second energy accumulator means  30  are non-rotatably connected by a bolt and the bolt extends into a groove or into a slotted hole, which is provided in input component  66  of second energy accumulator means  30 . 
         [0049]    As an alternative to the blockage loading of first energy accumulators, also a first relative rotation angle limiter device, which is not shown, can be provided in the configurations shown in  FIGS. 3-5  for limiting the relative rotation to the maximum first relative rotation angle, since first energy accumulators  68  of these particular embodiments are arc springs and second energy accumulators  70  are straight springs, and in case of arc springs, the risk of damages in case of blockage loading is less than with straight springs, it is provided in the embodiments shown in  FIGS. 3-5 , this can be provided accordingly, since this reduces the number of components or the manufacturing cost, that first energy accumulators  68  go into blockage in order to provide a limitation to the maximum first relative rotation angle, and second relative rotation angle limiter means  88  is provided for limiting the rotation to the maximum second relative rotation angle. This way a good setting can be reached for partial load operation. 
         [0050]    In the exemplary embodiments of hydrodynamic torque converter device  1  according to the invention, or of torsion vibration damper  10  according to  FIGS. 1-5 , first wall  92  for the radial support of at least one of first energy accumulator means  68  is provided. First wall  92  is disposed with reference to the radial direction of rotation axis  26  radially outside of first energy accumulator(s)  68 . First wall  92  is closed or substantially closed in circumferential direction with reference to the circumferential direction of rotation axis  26  of torsion vibration damper  10 . 
         [0051]    First wall  92  can, e.g., be a component of first housing  94 , in which first energy accumulators  68  are received. In the embodiments shown in  FIGS. 1 ,  2 ,  4 , and  5 , first housing  94  forming first wall  92  is formed substantially by input component  32  of first energy accumulator means  28  or by piston  80  and driver component  50 ,  52 ,  56 , or  58 . In the embodiment shown in  FIG. 3 , first housing  94  forming first wall  92  is formed substantially by input component  32  of first energy accumulator means  28 , by driver component  54 , or by means of component  32  or  54 , and by cover  96  integrally formed therewith or mounted thereon. 
         [0052]    First wall  94  is formed, in the embodiment shown in  FIG. 1 , by input component  32  of first energy accumulator means  28 , or by wall section of input component  32 . In the embodiments shown in  FIGS. 2-5 , first wall  92  is formed by the respective driver component  52 ,  54 ,  56 , or  58 , or by a wall section of the respective driver component  52 ,  54 ,  56 , or  58 . 
         [0053]    In the embodiments shown in  FIGS. 1-5 , at least one roller element means  98  or a roller shoe is provided for low friction support of at least one first energy accumulator  68  at first wall  92 . A common roller element means  98  can be provided for low friction support of all first energy accumulators  68 . It can also be provided that several roller element means  98  are provided for the low friction support of first energy accumulator(s)  68 . It can be provided, in particular, that the number of roller element means  98  corresponds to the number of first energy accumulators  68 . It can furthermore be provided that the number of roller element means  98  is greater than the number of first energy accumulators  68 . It can also be provided that the number of roller element means  98  is less than the number of first energy accumulators  68 . 
         [0054]    For the sake of simplicity, roller element means  98  is subsequently referred to, wherein as discussed, several roller element means  98  can be provided, which are then, e.g., respectively configured or disposed, as subsequently described with reference to roller element means  98 . Several roller element means  98  can be provided distributed circumferentially with reference to the circumferential direction of rotation axis  26 . 
         [0055]    Roller element means  98  comprises several roller elements  100 , which can be balls and which are balls in the present disclosure. Roller element means  98  is disposed between at least one first energy accumulator  68  and first wall  92 , and thus with reference to the radial direction of rotation axis  26 , in particular, radially in between first energy accumulator(s)  68  and first wall  92 . 
         [0056]    Roller element means  98  comprises roller element carrier  102 . Roller element carrier  102  receives or supports roller elements  100 . It is appreciated that the support may be provided when centrifugal forces act upon first energy accumulators  68 , and thus at high speeds of torsion vibration damper  10 . 
         [0057]    Roller element carrier  102  comprises portion  104 , which may be dish-shaped, and which is, with reference to the circumferential direction of rotation axis  26 , curved in circumferential direction in an arcuate shape, and curved transversal to the circumferential direction in an arcuate manner, wherein portion  104  can be provided as a curved groove. Portion  104  is disposed on the radially inner side of roller element carrier  102  with reference to the radial direction of rotation axis  26 . It can be provided that the circumferential curvature of portion  104 , with reference to the circumferential direction of rotation axis  26 , substantially corresponds to a curvature in this direction of first energy accumulators  68 , configured as arc springs, and/or that the curvature of portion  104 , existing transversal to the circumferential direction, substantially corresponds to the outer curvature of the windings of first energy accumulators  68  configured as arc springs. It can further be provided that first energy accumulators  68  are supported, or can be supported at portion  104 , in particular, under the influence of centrifugal forces. However, it can also be provided that roller element carrier  102  provides mechanical support means, which are not shown in the figures, which engage one or several energy accumulators  68 . For example, roller element means  98  or roller element carrier  102  can be slipped onto first energy accumulator  68 , and thus in the portion of a winding section of first energy accumulator  68  disposed in the radially outer portion with reference to the radial direction of rotation axis  26 . 
         [0058]    This can, e.g., be provided, as described in German Patent No. DE 199 20 542 A1, with reference to the slider shoes and the energy accumulators or force accumulators described therein, so that the respective disclosure of DE 199 20 542 A1 is referred to incorporated by reference into the present disclosure as a preferred improvement in its entirety. 
         [0059]    In the embodiments shown in  FIGS. 1-5 , roller elements  100  are disposed on the radial outside of roller element carrier  102  with reference to the radial direction of rotation axis  26 . This is performed therein, so that roller elements  100  are disposed between roller element carrier  102  and first wall  92 , or first wall  94 , so that they can support roller element carrier  102  at first wall  92  and at first housing  94 . 
         [0060]    In the embodiments shown in  FIGS. 1-5 , roller elements  100  of at least one roller element means  98  are configured so that they form several rows, which are spaced apart from one another in axial direction, when viewed in axial direction of rotation axis  26  of torsion vibration damper  10 . The rows are configured respectively by several balls or roller elements  100 , which are distributed in circumferential direction with reference to rotation axis  26 . 
         [0061]    It can be provided that first wall  92 , first housing  94 , or dish  106  inserted herein, in particular, non-rotatably relative to first wall  92  or relative to first housing  94 , which is, e.g., a hardened dish, and/or roller element carrier  102  forms, e.g., groove-shaped running surfaces for roller elements  100 , configured as balls. 
         [0062]    It can furthermore be provided, although not shown in the figures, that first energy accumulators  68  can also be supported with reference to the axial direction of rotation axis  26  in axial direction at first housing  94 , and thus in both orientations of the axial direction. Thus, it can be provided that, in the axial direction between walls of housing  94  and roller element carrier  102 , roller elements, in particular, balls, are provided. 
         [0063]    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.
