CROSS-REFERENCE TO RELATED APPLICATION 
     This application claims priority to German Patent Application No. 102014015539.0, filed Oct. 21, 2014, which is incorporated herein by reference in its entirety. 
     TECHNICAL FIELD 
     The invention relates to a support structure component for connecting a spring strut to a vehicle body. The invention furthermore relates to a vehicle body having such a support structure component. Furthermore, the invention relates to a method for mounting a spring strut on a vehicle body. 
     BACKGROUND 
     Support structure components of the type addressed herein are arranged for example in the region of the engine compartment of a motor vehicle and form a part of the motor vehicle body. The support structure components are usually designed as dome-shaped sheet metal components. The dome portion of the support structure component forms an upper end, which opens downwardly. The spring strut is installed by being pushed into the dome-sheet metal component and positioned from the bottom. Following this, the spring strut is attached to the dome portion of the support structure component. For this purpose, a threaded fastener attachment is usually employed which is attached to the dome-shaped support structure component from the top so that the spring strut is fastened against the bottom of the dome-shaped support structure component from top. 
     This results in that on the one hand the engine hood has to be opened up to now for attaching the spring strut to the vehicle body in order to perform the necessary threaded connection from the top. A further consequence is that the separating joint between the engine hood and the fender has to be configured so that the threaded portion for the spring strut on the dome-shaped support structure component of the vehicle body still remains accessible from the top. Because of this, flexibility in the development of new and/or improved configurations for motor vehicles is limited, for example with the consequence that the production process, the manufacturing costs and the repair friendliness of a motor vehicle can be negatively influenced. 
     SUMMARY 
     An embodiment of the invention is based on the object of proposing at least one possibility for connecting a spring strut to a vehicle body, by way of which the configuration freedom in the new development or further development of a motor vehicle less impaired than previously. 
     For solving the object, a support structure component is proposed for connecting a spring strut to a vehicle body with at least one connection section for connection to a vehicle body and with at least one flange section, which is designed for attaching a spring strut mount having a basic body on which a spring strut is mounted. In addition, a construction unit having a support structure component for connecting a spring strut to a vehicle body with at least one connection section for connection to a vehicle body and with at least one flange section, which is designed for attaching a spring strut mounting, on which a spring strut is mounted, and the vehicle body, in particular front car, having a side member, a longitudinal structure substantially running in longitudinal direction of the side member and the support structure component arranged in between, which is attached with a connection section on the side member and with another connection section on the longitudinal structure is proposed for solving the object. An assembly method for mounting a spring strut on a vehicle body provided with a support structure component, in particular a vehicle body, wherein the spring strut is first mounted on a spring strut mount and subsequently the spring strut mount together with the spring strut is brought into attaching position against the support structure component from the bottom and then attached to the support structure component from the bottom is proposed furthermore for solving the object. Advantageous configurations are obtained from the claims, the following description and the figures. 
     According to an embodiment of the invention, a support structure component for connecting a spring strut to a vehicle body includes at least one connecting section for connection to a vehicle body, for example for connection to a side member and/or a wheel installation brace. The support structure further includes at least one flange section, which is designed for attaching a spring strut mount, on which a spring strut is mounted, for example by an end of the spring strut being received and in particular attached in the spring strut mount. The flange section includes at least one connecting section, on which a spring strut mount can be received and/or attached. 
     By way of the support structure component the spring strut is not directly mounted to the vehicle body. By way of the support structure component, a body component is realized which although interacting with the spring strut mount via the flange section, to which however the spring strut mount can only be attached following its attachment to the vehicle body. In this regard, the support structure component makes possible that pushing the spring strut into the spring strut mount and any fastening of the spring strut against the spring strut mount is carried out outside the vehicle body, i.e. spatially separately from the support structure component. Because of this, a vehicle body provided with the support structure component need no longer be configured accessible from the outside for attaching the spring strut. In this regard, great configuration freedom results from this in the new development or further development of a motor vehicle. 
     Opportunity offers that the flange section is designed for the materially joined, non-positively joined and/or positively joined connecting of the spring strut mounting. Because of this, permanently durable attaching of the spring strut mounting to the support structure component is possible in a flexible manner. 
     For example, at least one connector is provided on the support structure component in the region of the flange section, against which a counter-connecting member can be brought into operational connection subject to connecting the spring strut mount. Because of this, the spring strut mount is easy to attach to the support structure component since the connecting member is already arranged thereon. This favors that the counter-connecting member is also brought against the connection member in regions of the vehicle body with difficult access, in particular when the connection member is held at least assembly-fixed on the support structure component. 
     In a technically simple manner, the spring strut mount can be connected to the support structure component when, according to a configuration of the present disclosure, the connection member is a thread-guiding part, which can be brought into operational connection against the counter-connection member by threaded fastening. For example, the connection member is a nut, in particular weld nut, which is arranged fixed on the support structure, for example welded to the same so that for attaching the spring strut mount a threaded fastener such as a screw or bolt can be utilized as counter-connection member. In the case of a vehicle body provided with the support structure component, assembly of the spring strut mount on the support structure component from beneath, for example from the below the engine compartment, is facilitated. 
     According to a further configuration of the present disclosure it is provided that the support structure component is formed by a shell structure having at least two shells or includes such a shell structure. By way of this two or multi-part structure, an adequately durable body structure is formed with relatively little use of material in order to withstand forces acting via the mounted spring strut. 
     According to a further configuration of the present disclosure one of the shells forms or includes a wheel housing section and the other shell serves as reinforcing structure, for example for the wheel housing section, aims in the same direction. 
     To further reinforce or stiffen the support structure component opportunity offers that according to a further configuration of the present disclosure the shells are structurally connected to one another subject to forming at least one hollow profile, wherein the at least one hollow profile with its longitudinal extension extends transversely to the longitudinal extension of the preferentially elongated connection section. 
     A further configuration of the present disclosure provides shells that are structurally connected to one another subject to forming at least two hollow profiles, wherein between the hollow profiles, in particular in the direction of their longitudinal extension, the support structure component has a passage opening for receiving an end of a spring strut. Because of this, effective bending stiffening of the support structure component is realized in the region of the passage opening. Any acting transverse forces are thereby effectively counteracted. 
     The passage opening is realized in a technically simple manner when according to a configuration of the present disclosure the shells include a passage opening each, wherein the passage openings are substantially arranged aligned or congruent with one another. 
     It can be provided that the at least one connecting member is arranged in the region of the at least one hollow profile and the hollow space of the hollow profile is bridged by a sleeve element, which serves for receiving a counter-connection member that can be brought into operational connection with the connection member. Because of this, the hollow profile in the region of one or multiple connecting points for attaching the spring strut mount on the support structure component is stiffened so that weakening of the hollow profile for example because of a compression of the hollow space during the attaching of the spring strut mount on the support structure component is avoided. 
     The present disclosure further includes a spring strut mount for attaching to the flange section of the support structure component described above or a support structure component of the type described above. The spring strut mount has a basic body, on which a spring strut for a motor vehicle, for example a McPherson spring strut can be mounted. The spring strut mount is a separate component, which is designed for assembly to the support structure component. Because of this, a high degree of flexibility for mounting a spring strut to an associated vehicle body is achieved, so that a high degree of configuration freedom is obtained in the further development or new development of motor vehicles. For example, the spring strut can be mounted on the support structure component even before mounting the spring strut mount or the mounting of the spring strut to the basic body can take place only after the mounting on the spring strut mount on the support structure component. 
     Opportunity offers that the basic body is substantially designed dome-shaped. Because of this, improved force absorption from the spring strut to the vehicle body is attained. Dome-shaped is to mean in particular that the basic body is substantially designed in a semi-spherical shape and/or bell-shaped. 
     Opportunity offers, further, that in the region of the open end of the basic body at least one connecting section projecting towards the outside is provided, so that the basic body can be introduced into the support structure component through a passage opening and the connection section serves as stop against the support structure component. In particular, the dimensions of the basic body to this end substantially correspond to those of the passage opening. Because of this, connecting the spring strut mount to the support structure component can be realized in a technically simple manner wherein at the same time the spring strut mount projects out of the support structure component dome-like and thereby optimal force introduction from the spring strut via the spring strut mount to the support structure component and thus to the vehicle body is attained. 
     Opportunity offers, further, that the spring strut mount includes a metal die casting, in particular light metal die casting or includes such components. Because of this, the spring strut mount is relatively light in weight, adequately stable and can be realized relatively cost-effectively with adequate production tolerance. 
     Advantageously, the spring strut mount can include a rib structure. By way of the rib structure, a further measure for stiffening the spring strut mount is realized. 
     A possible configuration of the present disclosure consists in that the basic body includes a passage opening, for example in its bottom, so that an end of a spring strut can be inserted and screwed against the rimming of the passage opening. Because of this, connecting the spring strut to the spring strut mount is possible in a technically simple manner. 
     Alternatively it can also be provided that the basic body includes at least one, but preferably multiple projections, for example domes, on which a spring strut can be connected by means of screw attaching. For example, the projections can be provided with an attaching thread, in particular an attaching thread cut in thereon. Insofar as the spring strut mount includes a rib structure it can be provided that the projections for connecting the spring strut are connected to the rib structure in order to stabilize the spring strut mount in the region of the attaching points for the spring strut. 
     Furthermore, the present disclosure includes a construction unit, in particular preassembled construction unit, with the spring strut mount described above or a spring strut mount of the type described above and a spring strut, for example a McPherson spring strut. In particular, the spring strut includes a shock absorber element, in particular a rod-shaped shock absorber element, and a spring element. In particular, the shock absorber element is mounted on the spring strut mount and the spring element supports itself against the spring strut mount. For example, the spring element is formed by a coil spring, which is put over the shock absorber element. By way of the construction unit, mounting the spring strut to a vehicle body including a support structure component of the type described above can be carried out in a simple manner, in particular the spring strut can thereby be mounted to the vehicle body from the bottom with little assembly effort. 
     In addition to this, the present disclosure includes a vehicle body, in particular a front car, with a side member, a longitudinal structure running substantially in longitudinal direction of the side member and a support structure component of the type described above or the support structure component described above arranged in between, which with a connecting section is attached to the side member and with another connecting section to the longitudinal structure. Because of this, the vehicle body is adequately stiffened in the region of the installation of a spring strut so that forces acting via the spring strut on the support structure can be optimally absorbed by the vehicle body. The longitudinal structure is formed for example by way of a wheel installation brace. 
     According to a configuration of the present disclosure it is provided that the support structure component is attached to the vehicle body in such a manner that the construction unit described above or a construction unit of the type described above can be brought into attaching position against the support structure component from the bottom and in particular can also be attached to the support structure component from the bottom. This results in a facilitation during the assembly of the motor vehicle since both inserting into the attaching position as well as the attaching proper is effected from one side. Any assembly steps from the top, for example by way of the engine compartment opening, are avoided. Because of this a major configuration freedom of the motor vehicle in the region of the engine hood and of the fender is attained since in the configuration any assembly access into the engine compartment from the top, for example for attaching the spring strut, is no longer necessary. 
     The present disclosure also includes a method for mounting a spring strut of a vehicle body provided with the support structure component described above or provided with a support structure component of the type described above, in particular the vehicle body described above or a vehicle body of the type described above. With the method, the spring strut is first mounted on a spring strut mount, for example the spring strut mount described above or a spring strut mount of the type described above and the spring strut mount together with the spring strut is subsequently brought into attaching position against the support structure component from below and then attached on the support structure component from below. By way of the method, any assembly access from the top for example in the engine compartment, for attaching the spring strut, is no longer necessary. This produces major configuration freedom in the new development or further development of motor vehicles. 
     Further objectives, advantages, features and application possibilities of the present invention are obtained from the following description of an exemplary embodiment.

     DETAILED DESCRIPTION 
     The following detailed description is merely exemplary in nature and is not intended to limit the invention or the application and uses of the invention. Furthermore, there is no intention to be bound by any theory presented in the preceding background of the invention or the following detailed description. 
       FIG. 1  shows—in schematic representation—a possible embodiment of a vehicle body  200 , which is exemplarily shown in the region of the left side of its front car. From  FIG. 1 , a side member  210  of the vehicle body  200  and a longitudinal structure  220  extending spaced from the same is visible. The side structure  220  can be a wheel installation brace. Furthermore, a front wall  230  is at least partially visible from  FIG. 1 , which extends transversely to the side member  210  and the longitudinal structure  220  and can merge into a lateral front wall  240  on the outside. 
     The side member  210  and the longitudinal structure  220  seen in forward driving direction  400  form a receiving space for one of the wheels of the motor vehicle in the region in front of the front wall  230 . In order to be able to mount a spring strut (not shown in  FIG. 1 ) to the vehicle body  200 , a support structure component  1  is provided, which is connected to the vehicle body  200  by means of at least one connection section  2 . For example, the support structure component  1  can include two connection sections  2   a  and  2   b , wherein the one connection section  2   a  is structurally connected to the longitudinal structure  220  and the other connection section  2   b  to the side member  210 , in particular by means of welding, riveting, clinching and/or bonding. The support structure component  1  extends between the connection sections  2   a  and  2   b  substantially transversely to the longitudinal extension of the vehicle body  200 , i.e. transversely to the forward driving direction  400  and bridges the region between the side member  210  and the longitudinal structure  220  seen in forward driving direction  400 , in front of the front wall  230 . 
     The support structure component  1  further includes at least one flange section  3 , which is designed for attaching a spring strut mount (not shown in  FIG. 1 ). For attaching the spring strut mount, at least one connection member  4  can be arranged on the support structure component  1 , in particular arranged in a fixed manner. The connection member  4  can be a screw element  5 , for example a weld nut, which is preferentially arranged in the installation state of the support structure component  1  top side so that a counter-connection member (not shown in  FIG. 1 ) can be screwed from the bottom into operational connection with the connection member  4  or into the screw element  5  and the attaching of the spring strut mount from the bottom on the support structure component  1  thereby takes place from the bottom. 
     The concept described here is based on the idea of providing a spring strut mount as a separate component to the support structure component  1 , so that the spring strut mount can be mounted on a spring strut in advance independently of the spring strut mount  1  and subsequently the spring strut mount mounted together with the spring strut on the support structure component  1  already attached to the vehicle body  200 . The spring strut is therefore only mounted on the vehicle body  200  via the spring strut mount. The spring strut mount together with the spring strut can be brought into attaching position on the support structure component  1  from the bottom and subsequently also attached on the support structure component  1  from the bottom. A possible configuration of the support structure component  1  and a possible configuration of the associated spring strut mount is shown in the further figures and described in the following. 
     Preferably, the support structure component  1  is formed by a shell structure having at least two shells  6  and  7  or includes such a shell structure.  FIGS. 2, 3 and 4  show the construction of the support structure component  1  with such a shell structure.  FIG. 2  shows the support structure component  1  with the shell  7 , which in the installation state on the vehicle body  200  preferably forms the shell located at the top. The connection sections  2   a  and  2   b  evident from  FIG. 1  are arranged on the shell  7 . The at least one connection member  4  is also arranged on the shell  7 . 
       FIGS. 3 and 4  show the support structure component  1  with its other shell  6 , which in the installed state on the vehicle body  200  preferably forms the shell located at the bottom with respect to the shell  7 . Preferably, the shell  6  at its ends directed to the side member  210  and the longitudinal structure  220  forms a separate connection section  2 ′ a  and  2 ′ b  each. By means of the connection section  2 ′ a , the shell  6  can be structurally connected or is structurally connected to the longitudinal structure  220 . The shell  6  can be structurally connected or is structurally connected with the connection section  2 ′ b  to the side member  220 , preferentially to the closing plate  250  of the side member  210 . For example, the connection sections  2 ′ a  and  2 ′ b  of the shell  6  and the connection sections  2   a  and  2   b  of the shell  7  are attached on the side member  210  and the longitudinal structure  220  by means of multiple, preferentially concentrated structural connections  15 , such as for example spot welds. 
     The shells  6  and  7  face one another with one of their flat sides each and lie on top of one another with their respective flat sides. The shell  6  located at the bottom preferably forms a wheel installation structure, in particular a wheel installation plate, and the shell  7  located above that, serves as reinforcing structure for reinforcing the shell  6 . 
     To further stiffen the support structure component  1  it can be provided that the shells  6  and  7  are connected to one another subject to forming at least one hollow profile, wherein the hollow profile with its longitudinal extension extends transversely to the longitudinal extension of the connection section  2  of the support structure component  1 . The at least one hollow profile is evident from the sectional representation in  FIG. 9  and there marked with the reference number  8  and  9  respectively. The hollow profile  8  and  9  respectively can be formed by a set-off flat region  16  on one of the shells  6  and  7 , for example of the shell  6 , and a side wall region of the other shell corresponding therewith, for example the shell  7 , which is evident with the help of  FIGS. 2, 3 and 4 . 
     Preferably, the support structure component  1  includes two such hollow profiles  8  and  9 , which are preferably arranged in the lateral end region of the support structure component  1  and a passage opening  10  is provided on the support structure component  1  in between ( FIG. 9 ). Preferably, the passage opening  10  is formed by a passage opening  11  in the shell  6  and a passage opening  12  in the shell  7  which substantially corresponds therewith. The passage opening  10  of the support structure component  1  serves for receiving a part of a spring strut mount (not shown in the  FIGS. 2 to 4 ). 
     As is evident in particular from  FIG. 2 , the at least one connection member  4  can be arranged in the region of one of the hollow profiles  8  and  9  respectively of the support structure component  1 . For bridging the hollow space of the respective hollow profile  8  and  9  at least one associated sleeve element  13  is preferably provided, so that a counter-connection member passed through the sleeve element  13 , which enters into operational contact against the connection member  4  of the support structure component  1 , can be brought into attaching position without the hollow space of the associated hollow profile  8  and  9  respectively being thereby compressed and unintentionally deformed. 
       FIG. 5  shows a possible embodiment of a spring strut mount  50 , which is designed for attaching on the support structure component  1  and includes a basic body  51 , in order to be able to mount a spring strut for a motor vehicle (not shown in the  FIG. 5 ) thereon. 
     Preferably, the basic body  51  is designed dome-like and at its open end  52  includes at least one, preferentially two connection sections  53  and  54  projecting towards the outside opposite to one another so that the basic body  51  can be pushed in through the passage opening  10  in the support structure component  1  and the connection sections  53  and  54  serve as stop against the support structure component  1 . 
     Preferably, the connection sections  53  and  54  each include at least one passage hole by means of which the spring strut mount  50  can be attached on the support structure component  1 , preferentially on the connection sections  2  provided there. For example, the passage openings  55  serve for receiving a counter-connection member (not shown in  FIG. 5 ), which is inserted through the respective associated passage hole  55  in order to be able to enter into operational contact with the connection member  4  that is present on the support structure component  1 . 
     The connection sections  53  and  54  can each include at least one rib or similar rib structure  56 , through which the attaching region of the spring strut mount  50  is further stiffened for connection to the support structure component  1 . 
     A sealing element  57  can also be provided, which is designed for example as a ring seal and in its center at least partially receives the basic body  51  and preferably supports itself against an edge section  58  projecting towards the outside on the open end  52  of the spring strut mount  50  or is supported thereon. Preferably, the edge section  58  is circumferential and serves for the further reinforcement of the spring strut mount  50 . By means of the sealing element  57 , the spring strut mount  50  is sealed towards the outside in the installed state on the support structure component  1 . For example, the wheel arch that is present in the region of the spring strut is sealed relative to the engine compartment so that while driving no splash water from the tires can enter the engine compartment. 
     The spring strut mount  50  can include a passage opening  59  in the region of its bottom, into which an end of a spring strut (not shown in  FIG. 5 ) can be pushed, for example in order to utilize the passage opening  58  for attaching the spring strut on the spring strut mount  50 . 
       FIG. 6  shows the spring strut mount  50  with a spring strut  100  mounted thereon. The spring strut  100  and the spring strut mount  50  preferably form a preassembled construction unit  300 . 
     Preferably, the spring strut  100  includes an elongated shock absorber element  110  and a spring element  120 . The spring element  120  can be a coil spring, into the interior of which the shock absorber element  110  is pushed in or pushed through. For example, the spring strut  100  is a McPherson spring strut. 
     As is evident from  FIG. 6 , the spring element  120  can support itself towards the bottom against a spring retainer  140 , which is arranged for example on the shock absorber element  110  fixed on the housing. 
     Preferably, the spring strut  100  is pushed in through the passage opening  59  in the spring strut mount  50  in particular with an end of the shock absorber element  110  and screwed against the rimming of the passage opening  59  by means of a thread element  130  such as for example a attaching nut. 
     The construction unit  300  with the spring strut mount  50  and the spring strut  100  can additionally include at least one component of a braking device  500  and/or a steering device  600  and form a preassembled construction unit. In a later assembly step, this construction unit can be mounted on the vehicle body  200 , wherein the spring strut mount  50  is attached on the support structure component  1  of the vehicle body  200 . 
       FIG. 7  shows the construction unit  300  according to  FIG. 6  with the components of the braking device  500  and steering device  600  in the assembled state on the vehicle body  200 , wherein the spring strut mount  50  is attached on the support structure component  1 .  FIG. 8  shows the assembly according to  FIG. 7  in a sectional representation along the section line A-A of  FIG. 7 .  FIG. 8  shows the assembly of  FIG. 7  in a sectional representation along the section line B-B of  FIG. 7 . 
     As is evident from  FIG. 8 , the spring strut  100  on its upper end is inserted in the passage opening  59  of the spring strut mount  50  and screwed against the spring strut mount  50  and screwed against the basic body  51  by means of the thread element  130 . As is additionally evident from this, the spring element  120  can be supported on a buffer element  150  towards the top, wherein the buffer element  150  in turn can support itself against the thread element  130  via a support bearing element  160 . 
     The sectional representation in  FIG. 9  shows the design of the hollow profiles  8  and  9  from the shells  6  and  7  of the support structure component  1 . For attaching the spring strut mount  50  on the support structure component  1 , a counter-connection member  60  each is brought into operational contact with the associated connection member  4 . Provided that the connection member  4  is designed as a screw element  5 , the counter-connection member  60  is designed as a counter-screw element  61 , which inserted in the associated sleeve element  13  is screwed into the screw element  5 . The respective sleeve element  13  in this case bridges a hollow space  14  formed by the hollow profile  8  and  9  respectively. 
     As is evident from viewing  FIG. 9  together with  FIG. 7 , the spring strut mount  50  is pushed into the support structure component  1  from the bottom, in particular its passage opening  10  and positioned. In addition to this, the spring strut mount  50  is also attached to the support structure component  1  from the bottom. To this end, the counter-connection member  60  is brought into operational contact against the connection member  4  from the bottom in the direction of the respective arrow  410 . Provided the connection member  4  and the counter-connection member  60  form a screw connection, the feed direction for screwing in the counter-connection member  60  is the movement direction according to the arrow  410 . 
       FIG. 10  shows the construction according to  FIG. 7  in a view from the bottom. As is evident from this, the counter-connection member  60  is accessible from the bottom.
