Description

[0001] The invention relates to an integral support for a motor vehicle according to patent claim 1. Furthermore, the invention relates to an arrangement of a torsion bar on an integral support for a motor vehicle according to patent claim 3.

[0002] EP 2 283 959 A1 discloses a fastening arrangement comprising a stud bolt with a bolt portion provided with an external thread and with a welding end for welding to a workpiece to be welded.

[0003] Furthermore, DE 101 56 403 C1 discloses a fastening system for fastening a body to a metallic component, in particular for fastening a body to a metal sheet such as a body panel of a motor vehicle, using a metallic threaded bolt.

[0004] The object of the present invention is to provide an integral support for a motor vehicle and an arrangement of a torsion bar on an integral support for a motor vehicle, so that the weight of the motor vehicle can be kept particularly low.

[0005] This object is achieved according to the invention by an integral support for a motor vehicle having the features of patent claim 1 and by an arrangement of a torsion bar on an integral support for a motor vehicle having the features of patent claim 3. Advantageous embodiments with expedient further developments of the invention are specified in the remaining claims.

[0006] A first aspect of the invention relates to an integral support for a motor vehicle, which is designed, for example, as a passenger car. The motor vehicle, particularly in its fully manufactured state, preferably comprises the integral support.

[0007] The integral support can be understood, in particular, as a subframe, which can also be referred to as an assembly support, axle support, or subframe. For example, body-side pivot points of wheel suspensions can be or are attached to the integral support. In other words, at least one wheel suspension of the motor vehicle can be or is coupled to a preferably self-supporting body of the motor vehicle via the integral support.

[0008] In order to be able to keep the weight of the motor vehicle particularly low, the integral support has at least one receiving opening in which a bearing device can be or is received at least partially, in particular predominantly or completely. In other words, the bearing device can be or is arranged in the receiving opening at least in part, in particular predominantly or completely. This means that the bearing device extends at least in part, in particular predominantly or completely, within the receiving opening. A torsion bar can be pivoted about a pivot axis relative to the integral support via the bearing device, for example directly, to be held or is held on the integral support.In other words, the torsion bar is or can be fastened to the integral support via the bearing device or by means of the bearing device, wherein the torsion bar is or can be pivoted about the pivot axis relative to the integral support. This means that the torsion bar is or can be mounted on the integral support via the bearing device or by means of the bearing device, in particular pivotable about the pivot axis relative to the integral support.

[0009] The bearing device is designed, for example, as a rubber bearing. The receiving opening is designed, for example, as a recess, which can be referred to as a receiving recess. The recess can be understood, in particular, as a depression formed in the integral support.

[0010] The torsion bar is preferably designed as a stabilizer or is at least part of the stabilizer. The stabilizer is preferably provided or designed for a chassis of the motor vehicle. The stabilizer can be understood in particular as a component in the chassis or for the chassis of the motor vehicle, for example acting as a spring, in particular a torsion spring, wherein the stabilizer can be used to particularly reduce roll angles that arise when the motor vehicle corners. Furthermore, the stabilizer can be used to adjust self-steering behavior, in particular during particularly high lateral accelerations. Thus, the stabilizer can be used to influence a rolling movement of the motor vehicle, also referred to as roll, and in particular to keep this particularly low.

[0011] The invention is based in particular on the following findings and considerations: In a conventional integral support, for example, the rubber mount is clamped between a first and a second clamp, for example, an upper and a lower clamp, in order to apply a specific preload. These two clamps can then be connected to each other, for example, by welding. For example, at least one of these clamps is U-shaped. These clamps can have a negative impact on the overall weight of the motor vehicle.

[0012] In contrast, the weight of the motor vehicle can be kept particularly low by means of the integral support according to the invention. Because the integral support has the receiving opening in which the bearing device can be at least partially received or accommodated, it is possible, for example, to eliminate at least one of the clamps. Thus, for example, the larger, U-shaped clamp can be replaced by the integral support itself. In other words, for example, a U-shaped part of a torsion bar clamp can be replaced by the integral support. A receiving and / or fastening function provided for the bearing device or the torsion bar, which in the conventional integral support is assumed, for example, by the clamps, can thus be performed at least partially in the integral support according to the invention by the integral support itself, in particular by the receiving opening.This means, for example, that at least one of the clamps can be omitted. The number of components in the motor vehicle can therefore be kept particularly low, which means that the weight of the vehicle can be significantly reduced. For example, the weight of an assembly comprising the torsion bar, which can also be referred to as the “assembly torsion bar,” can be reduced by approximately 10 percent. Furthermore, because the bearing device can be received or is received in the receiving opening, the bearing device can be connected to the integral support in a particularly advantageous manner, in particular in a particularly space-saving and / or particularly rigid manner. In contrast, with the conventional integral support, the bearing device can be connected to the integral support less rigidly due to the flexibility provided by the clamps.

[0013] In a further embodiment, it is provided that the pivot axis of the torsion bar to be held or held on the integral support via the bearing device runs through the receiving opening, i.e. through the receiving opening. This means that the pivot axis runs through the receiving opening when the torsion bar is held on the integral support via the bearing device. In other words, the receiving opening is designed to arrange or receive the pivot axis. The pivot axis is, for example, a central axis of the torsion bar or at least one torsion bar part of the torsion bar, wherein this central axis preferably extends in the axial direction of the torsion bar or the torsion bar part. Thus, the central axis or a center point of the torsion bar can be located in the receiving opening.As a result, the fastening and / or support function of the torsion bar can be performed at least predominantly by the integral support, which allows the weight of the vehicle to be kept particularly low, since, for example, additional components can be omitted or, if these additional components are required, these components can be dimensioned particularly small, i.e., to save weight. Furthermore, the bearing device can be accommodated particularly securely, in particular particularly rigidly, in the integral support or the support opening.

[0014] A second aspect of the invention relates to an arrangement of at least one torsion bar on an integral support, in particular according to the first aspect of the invention, for a motor vehicle or the motor vehicle, which is designed, for example, as a passenger car. Advantages and advantageous embodiments of the first aspect of the invention are to be regarded as advantages and advantageous embodiments of the second aspect of the invention, and vice versa.

[0015] The torsion bar is pivotable about at least one pivot axis relative to the integral support via at least one bearing device, for example, at least indirectly or directly, and is held or mounted on the integral support. The integral support is designed, for example, as a front axle integral support or as a rear axle integral support, but preferably as a front axle integral support. In other words, the integral support is to be arranged or is arranged on a front axle or a rear axle of the motor vehicle.

[0016] In order to be able to keep the weight of the motor vehicle particularly low, the integral support has at least one receiving opening in which the bearing device is at least partially, in particular predominantly or completely, received or arranged. For example, the receiving opening is at least partially, in particular predominantly or completely, bounded by at least one wall of the integral support. In other words, the receiving opening is or will be formed at least partially, in particular predominantly or completely, by the wall.

[0017] In order to be able to keep the weight of the motor vehicle particularly low, a further embodiment provides that the pivot axis runs through the receiving opening, i.e. through the receiving opening. In other words, the torsion bar can be pivoted about the pivot axis relative to the integral support via the bearing device in the receiving opening at least partially, in particular predominantly or completely, so that the pivot axis runs through the receiving opening, i.e. that at least a longitudinal region of the pivot axis is located within the receiving opening. Thus, for example, the pivot axis is at least predominantly, i.e. in particular more than 50 percent, surrounded by the integral support.

[0018] In a further embodiment, it is provided that at least one length region of the torsion bar, in particular extending in the axial direction of the torsion bar, is completely arranged or received in the receiving opening. In other words, a depth and / or a width of the receiving opening is at least as large as, but preferably larger than, a diameter of the torsion bar, wherein the torsion bar has this diameter in particular in the aforementioned length region. This can prevent the torsion bar, in particular in the length region, from protruding from the receiving opening, in particular in the radial direction of the torsion bar. The torsion bar can therefore be mounted particularly securely on the integral support via the bearing device. In this way, the aforementioned rigidity can be particularly increased.Furthermore, additional components for fastening the bearing device to the integral support can be omitted or these components can be dimensioned to save weight.

[0019] In a further embodiment, it is provided that the torsion bar is pressed, in particular directly, into the bearing device. In other words, the torsion bar is preloaded in the bearing device, in particular rotatable or pivotable about the pivot axis. This can bring about a bearing preload of the bearing device, whereby it can be ensured, for example, that the bearing device is always subjected to compressive loads during operation of the motor vehicle, and in particular tensile loads can be avoided. Furthermore, noises, for example in the form of creaking noises, which can be caused by relative movements, can be kept particularly low. The acoustics of the motor vehicle can thus be particularly improved. Preferably, the bearing device is pressed, in particular preloaded, into the receiving opening.This means that the pressing of the torsion bar into the bearing device or by the aforementioned bearing preload can be effected or generated by pressing the bearing device into the receiving opening, i.e. for example by a seat of the bearing device in the receiving opening.

[0020] In a further embodiment, it is provided that the receiving opening, in particular in the radial direction of the receiving opening and / or the torsion bar, preferably the length region of the torsion bar, is at least partially covered by at least one cover element formed separately from the integral support and the bearing device. In other words, the receiving opening is or will be closed by means of the cover element, in particular completely. Thus, the receiving opening is, for example, open on at least one side and covered or closed on this side by the cover element. As a result, the bearing device can be arranged particularly securely in the receiving opening, whereby the torsion bar can be attached particularly securely to the integral support via the bearing device. Preferably, the cover element rests, in particular directly, on the bearing device.

[0021] The cover element is preferably designed as a fastening element that partially delimits the receiving opening. The delimitation of the receiving opening by the cover element preferably occurs in the radial direction of the receiving opening and / or the torsion bar, in particular in the length region. The delimitation preferably occurs on the aforementioned side on which the receiving opening, in particular viewed on its own, is open. By means of the fastening element, the bearing device is fastened, for example by means of at least one screw connection and / or by means of at least one welded connection, in particular directly, to the integral support, i.e. in its installed position in the receiving opening. This means that the holding or fastening of the bearing device to the integral support is or will be effected at least partially by the fastening element.For example, the fastening element is held or fastened to the integral support, in particular by means of the screw connection and / or the welded connection, in particular directly, wherein the bearing device is fastened to the integral support via the fastening element in a form-fitting and / or force-fitting manner. Thus, the bearing device is fastened to the integral support, for example, by means of a clamping connection at least partially effected by the fastening element, wherein the fastening element is in turn fastened to the integral support, for example via the aforementioned screw connection and / or welded connection, in particular bypassing the bearing device. The fastening element allows the bearing device to be fastened particularly securely to the integral support, whereby the torsion bar can be mounted particularly securely on the integral support.Furthermore, the fastening element allows the fastening of the bearing device or the torsion bar to the integral support in a particularly weight-saving manner.

[0022] In a further embodiment, it is provided that the fastening element extends on sides of the receiving opening that are different from one another in the radial direction of the receiving opening and / or of the torsion bar, in particular in the length range. This means that the fastening element extends, in particular starting from a first side of the receiving opening to a second side of the receiving opening that is different from the first side, wherein the first and the second sides are different sides from one another in the radial direction of the receiving opening or of the torsion bar. In other words, at least one part of the fastening element is arranged on the first side and at least one second part of the fastening element, that is different from the part, is arranged on the second side.This allows the bearing device or torsion bar to be attached to the integral support in a particularly weight-saving and / or particularly secure manner.

[0023] Preferably, the first and the second side are sides facing away from each other in the radial direction of the receiving opening or of the torsion bar, in particular in the length region.

[0024] In a further embodiment, it is provided that the bearing device is or will be vulcanized onto the torsion bar, in particular directly. This means, for example, that the bearing device and the torsion bar are or will be connected to one another by vulcanization, in particular directly. In other words, the bearing device is designed as a bearing device vulcanized onto the torsion bar. This allows the bearing device and the torsion bar to be connected to one another in a particularly advantageous manner, for example in a particularly secure and / or particularly durable manner. Furthermore, this connection can be carried out in a particularly low-cost manner, whereby the manufacturing costs of the motor vehicle can be kept particularly low. The aforementioned vulcanization is in particular the vulcanization for producing the bearing device.This means that at least one vulcanization process is carried out to manufacture the bearing device, wherein the bearing device and the torsion bar are bonded to one another during or in connection with this vulcanization process. Alternatively, it is provided, for example, that the bearing device is clamped and / or glued, in particular directly, to or onto the torsion bar.

[0025] Further advantages, features, and details of the invention will become apparent from the following description of a preferred embodiment and from the drawings. The features and combinations of features mentioned above in the description, as well as the features and combinations of features mentioned below in the description of the figures and / or shown alone in the figures, can be used not only in the respective combinations specified, but also in other combinations or on their own, without departing from the scope of the invention.

[0026] Showing: Fig. 1 is a schematic perspective view of an arrangement according to the invention; and Fig. 2 a schematic and perspective detailed view of an arrangement according to the invention.

[0027] In the figures, identical or functionally identical elements are provided with the same reference symbols.

[0028] Fig. 1 shows in a schematic perspective view an arrangement of a torsion bar 1 on an integral support 2 for a motor vehicle 3. Thus, in Fig. 1 shows, in particular, a schematic and perspective partial view of the motor vehicle 3. The integral support 2 is designed in the exemplary embodiment as a front integral support, i.e., as a front integral support 2 relative to a longitudinal direction of the motor vehicle 3. The integral support 2 is formed, for example, from aluminum or an aluminum alloy. The torsion bar 1, which can also be referred to as a torsion bar, is preferably designed as a stabilizer for the motor vehicle 3, in particular for a chassis of the motor vehicle 3. The motor vehicle 3 preferably has the chassis.

[0029] For example, the motor vehicle 3, in particular the chassis, has at least two wheel suspensions 4, 5. The respective wheel suspension 4, 5 is designed to guide a respective vehicle wheel of the motor vehicle 3. This means that a first of the wheel suspensions 4 is designed to guide a first vehicle wheel of the motor vehicle 3, and the second of the wheel suspensions 5 is designed to guide a second vehicle wheel of the motor vehicle. In the present case, the wheel suspensions 4, 5 or the vehicle wheels are arranged on different sides of the motor vehicle 3 in the transverse direction of the motor vehicle 3. The respective vehicle wheel can be understood, in particular, as a ground contact element of the motor vehicle 3. The motor vehicle 3 can preferably be or is supported on a surface, for example a roadway, via the respective vehicle wheel.

[0030] For example, the respective wheel suspension 4, 5 each has a respective wheel carrier on which the respective vehicle wheel is or is to be mounted so as to be rotatable about a respective wheel rotation axis of the respective vehicle wheel. For example, the respective wheel suspension 4, 5 each has a respective wheel check arm provided for guiding the respective vehicle wheel. The respective wheel check arm has, for example, a respective first connection point via which the respective wheel check arm can be or is coupled in an articulated manner to a body, also referred to as the superstructure, of the motor vehicle 3 and / or the integral carrier 2. Furthermore, the respective wheel check arm has, for example, a respective second connection point via which the respective wheel check arm can be or is coupled in an articulated manner to the respective wheel carrier. The torsion bar 1 is formed separately from the wheel suspensions 4, 5.

[0031] For example, the torsion bar 1 has two lever parts 6a, 6b, wherein Fig. 1 only a first of these lever parts 6a is visible. In particular, the lever parts 6a, 6b are spaced apart from one another. The first lever part 6a is pivotable, for example, about a first pivot axis 7 relative to the integral support 2. The second lever part 6b is pivotable, for example, about a second pivot axis 8 relative to the integral support 2. The pivot axes 7, 8 run coaxially to one another in the present case. In other words, the pivot axes 7, 8 are arranged coaxially to one another. The first lever part 6a has, for example, a first coupling point 9, via which the first lever part 6a can be or is coupled to the first wheel suspension 4. Furthermore, the second lever part 6b has, for example, a second coupling point, via which the second lever part 6b can be or is coupled to the second wheel suspension 5.

[0032] For example, the torsion bar 1 has at least one stabilizer part 10, via which the lever parts 6a, 6b can be or are coupled to one another at least indirectly, in particular directly, in particular for influencing a roll angle of the motor vehicle 3 or for influencing a roll behavior of the motor vehicle 3. The stabilizer part 10 thus acts, for example, as a torsion bar spring, which can also be referred to as a torsion spring. As a result, the lever parts 6a, 6b can be pivoted relative to one another, in particular about the respective pivot axis 7, 8. In the present case, the lever parts 6a, 6b are mechanically connected to one another at least indirectly, in particular directly, via the stabilizer part 10. For example, the lever parts 6a, 6b and the stabilizer part 10 are formed integrally with one another.

[0033] The torsion bar 1, for example the first lever part 6a and / or the stabilizer part 10, is held on the integral support 2, for example directly, via at least one bearing device 11 about the pivot axis 7, which can also be referred to as the first pivot axis 7, relative to the integral support 2. In the Fig. 1, the torsion bar 1, in particular the second lever part and / or the stabilizer part 10, is held, in particular directly, on the integral support 2 via a second bearing device 12 formed separately from the bearing device 11, such that it can pivot about the second pivot axis 8 relative to the integral support 2. As a result, the bearing device 11 can also be referred to as the first bearing device 11. Thus, for example, the torsion bar 1 is held on the integral support 2 at a first bearing point via the first bearing device 11, such that it can pivot about the first pivot axis 7 relative to the integral support 2. Furthermore, for example, the torsion bar 1 is held on the integral support 2 at a second bearing point different from the first bearing point, such that it can pivot about the second pivot axis 8 relative to the integral support 2 via the second bearing device 12. The bearing points are preferably spaced apart from one another in the transverse direction of the vehicle.The respective bearing device 11, 12 can be understood, in particular, as a respective bearing. The respective bearing device 11, 12 is preferably designed as a respective rubber bearing.

[0034] In order to be able to keep the weight of the motor vehicle 3 particularly low, the integral support 2 has at least one receiving opening 13, in which at least one of the bearing devices 11, 12, for example the first bearing device 11, is at least partially, in particular predominantly or completely, received. In the exemplary embodiment, however, the integral support 2 has a second receiving opening 14, which is spaced apart from the receiving opening 13, in particular in the transverse direction of the vehicle, and in which the second bearing device 12 is at least partially, in particular predominantly or completely, received. The receiving opening 13 can therefore also be referred to as the first receiving opening 13. The respective bearing device 11, 12 can thus be integrated, in particular directly, into the integral support 2, whereby, for example, a respective conventional fastening clamp can be dispensed with. In Fig. 2 the arrangement is shown in a schematic and perspective detailed view, with the second bearing point in particular being illustrated as an example.

[0035] In the present case, the bearing devices 11, 12 are spaced apart from one another in the transverse direction of the vehicle. An axial direction of the first receiving opening 13 preferably runs parallel to the first pivot axis 7. An axial direction of the second receiving opening 14 preferably runs parallel to the second pivot axis 8.

[0036] As in Fig. 1, in the exemplary embodiment the first pivot axis 7 runs, in particular directly, through the first receiving opening 13. Furthermore, for example the second pivot axis 8 runs, in particular directly, through the second receiving opening 14. Thus, it is particularly provided that the respective pivot axis 7, 8 runs through both receiving openings 13, 14.

[0037] For example, the first receiving opening 13 is at least partially delimited or formed by a first wall 15 of the integral support 2, in particular by at least 180 degrees, for example by at least 220 degrees, in the circumferential direction of the first receiving opening 13. For example, the second receiving opening 14 is at least partially delimited or formed by a second wall 16 of the integral support 2, on the inside in the circumferential direction of the second receiving opening 14, by at least 180 degrees, for example by at least 220 degrees. Thus, for example, the first and / or the second wall 15, 16 surrounds the torsion bar 1 in its circumferential direction at least partially, for example by at least 180 degrees, preferably by at least 220 degrees.

[0038] In the exemplary embodiment, at least one longitudinal region 17 of the torsion bar 1 is arranged entirely in the first receiving opening 13, whereby, for example, the integral support 2, in particular the first wall 15, at least partially, in particular predominantly, surrounds the longitudinal region 17 in the circumferential direction of the longitudinal region 17. Furthermore, for example, a second longitudinal region 18 of the torsion bar 1, which is different from the longitudinal region 17, is completely received in the second receiving opening 14, whereby, for example, the integral support 2, in particular the second wall 16, at least partially, in particular predominantly, circumferentially surrounds the second longitudinal region 18 in its circumferential direction. The longitudinal region 17 can also be referred to as the first longitudinal region 17. The longitudinal regions 17, 18 are, in particular, different longitudinal regions from one another.For example, the length regions 17, 18 adjoin one another, in particular at least indirectly or directly, preferably in the transverse direction of the vehicle.

[0039] For example, the first bearing device 11, in particular together with the torsion bar 1 or the first longitudinal region 17, is pressed into the first receiving opening 13, i.e., into the integral support 2, whereby, for example, the torsion bar 1, in particular the first longitudinal region 17, is pressed into the first bearing device 11. Furthermore, for example, the second bearing device 13, in particular together with the torsion bar 1, is pressed into the second receiving opening 14, i.e., into the integral support 2, whereby, for example, the torsion bar 1, in particular the second longitudinal region 18, is pressed into the second bearing device 12.

[0040] In the Fig. 1, it is provided that the first receiving opening 13 is at least partially covered by a cover element 19 formed separately from the integral support 2 and the first bearing device 11, whereby, for example, the torsion bar 1, in particular the first longitudinal region 17 and / or the first pivot axis 7, are surrounded by the integral support 2, in particular the first wall 15, and the cover element 19, preferably over their entire circumference. Furthermore, for example, the second receiving opening 14 is at least partially covered by a second cover element 20 formed separately from the integral support 2, the bearing devices 11, 12 and the cover element 19, whereby, for example, the torsion bar 1, in particular the second longitudinal region 18 and / or the second pivot axis 8, are surrounded by the integral support 2, in particular the second wall 16, and the second cover element 20, preferably over their entire circumference.The cover element 19 can also be referred to as the first cover element. The cover elements 19, 20 are preferably spaced apart from one another, for example, in the transverse direction of the vehicle. As shown in . Fig. 1 and Fig. 2, in the present case, for example, the respective cover element 19, 20 is designed as a respective cover, in particular provided for the respective receiving opening 13, 14 or for closing the respective receiving opening 13, 14.

[0041] Preferably, the first cover element 19 is configured to correspond, at least in part, to the first bearing device 11. Furthermore, the second cover element 20 is preferably configured to correspond, at least in part, to the second bearing device 12. For example, the respective cover element 19, 20 is configured to be at least substantially flat.

[0042] In the exemplary embodiment, the first cover element 19 is designed as a fastening element 21 that partially delimits the first receiving opening 13 and can also be referred to as the first fastening element 21. The first bearing device 11, and thus in particular the torsion bar 1 at the first bearing point, is fastened to the integral support 2 by means of the first fastening element 21 or the first cover element 19. For this purpose, in the present case, the first cover element 19 or the first fastening element 21 is fastened to the integral support 2 at at least one fastening point 22, 23, preferably at at least two fastening points 22, 23, in particular directly, for example by means of a, in particular respective, screw connection. Thus, for example, the first cover element 19 or the first fastening element 21 is screwed to the respective fastening point 22, 23, in particular directly, to the integral support 2.In this case, the first cover element 19 or the first fastening element 21 rests, in particular directly, against the first bearing device 11, whereby, in particular, the first bearing device 11 is held or fixed in the first receiving opening 13. The fastening point 22 can be referred to as the first fastening point 22, and the fastening point 23 can be referred to as the second fastening point. The fastening points 22, 23 are preferably spaced apart from one another.

[0043] Furthermore, for example, the second cover element 20 is designed as a second fastening element 24 partially delimiting the second receiving opening 14, by means of which the second bearing device 12 and thereby in particular the torsion bar 1 is fastened to the second bearing point on the integral support 2. For this purpose, in the present case, the second cover element 20 or the second fastening element 24 is fastened to at least one fastening point 25, 26, but preferably to at least two fastening points 25, 26, on the integral support 2, for example by means of a, in particular respective, screw connection. Thus, for example, the cover element 20 or the second fastening element 24 is screwed to the respective fastening point 25, 26, in particular directly, to the integral support 2. The fastening point 25 can be referred to as the third fastening point and the fastening point 26 can be referred to as the fourth fastening point.In the present case, the second cover element or the second fastening element 24 rests, in particular directly, against the second bearing device 12, whereby in particular the second bearing device 12 is held or fixed in the second receiving opening 14. For example, the respective fastening element 21, 24 is designed as a respective sheet metal element, which can also be referred to as a fastening sheet metal element or simply as a holder or sheet metal holder.

[0044] In the exemplary embodiment, the first fastening element 21 or the first cover element 19 extends on sides 28, 29 of the first receiving opening 13 which are different from one another in the radial direction 27 of the first receiving opening 13. The first cover element 19 or the first fastening element 21 thus extends, for example, from a first of the sides 28 to the second of the sides 29. In particular, the first fastening point 22 is arranged on the first side 28 and the second fastening point 23 is arranged, in particular, on the second side 29. The sides 28, 29 are, for example, different sides 28, 29 in the longitudinal direction of the motor vehicle 3. Thus, for example, the first fastening point 22 is arranged in front of the first pivot axis 7 and / or the first receiving opening 13 in the longitudinal direction of the vehicle.Furthermore, for example, the second fastening point 23 is arranged in the vehicle longitudinal direction behind the first pivot axis 7 and / or the first receiving opening 13.

[0045] Equivalently, for example, the second cover element 20 or the second fastening element 24 extends on sides 31, 32 of the second receiving opening 14 that are different from one another in the radial direction 30 of the second receiving opening 14. The side 31 can be referred to as the third side and the side 32 can be referred to as the fourth side. Thus, the second cover element 20 or the second fastening element 24 extends, for example, from the third side 31 to the fourth side 32. In particular, the third fastening point 25 is arranged on the third side 31 and the fourth fastening point 26 is arranged in particular on the fourth side 32. For example, the sides 31, 32 are different sides from one another in the longitudinal direction of the motor vehicle 3.Thus, for example, the third fastening point 25 is arranged in front of the second pivot axis 8 and / or the second receiving opening 14 in the vehicle longitudinal direction and the fourth fastening point 26 is arranged, for example, behind the second pivot axis 8 and / or the second receiving opening 14 in the vehicle longitudinal direction.

[0046] For example, the first bearing device 11 is vulcanized, clamped, and / or glued, in particular directly, to or onto the torsion bar 1, in particular the first longitudinal region 17. Furthermore, the second bearing device 12, for example, is vulcanized, in particular directly, to or onto the torsion bar 1, in particular the second longitudinal region 18.

[0047] Overall, it can be seen that a respective clamp, for example a lower one, provided for fastening the torsion bar 1 can be replaced by a respective direct assembly of the respective bearing device 11, 12 in the integral support 2, in that the respective bearing device 11, 12 is accommodated in the respective receiving opening 13, 14. This can be understood in particular that a conventional stabilizer is attached to the integral support 2, for example on each side with two clamps that compress the respective rubber bearing with a certain preload. These clamps can consist of two parts, namely a straight part and a U-shaped part, which can also be referred to as a U-shaped clamp. Both parts can be connected to one another, for example by welding, after the preload has been applied.By accommodating the respective bearing device 11, 12 in the respective receiving opening 13, 14, the U-shaped clamp can be completely omitted, for example, since its function is replaced or performed by the integral support 2 itself, for example on the front axle. The torsion bar 1 connected to the respective rubber bearing can be pressed into the integral support 2 and then screwed, for example from above, to the respective cover element 19, 20, which can be designed as a respective cover plate, for example. In this way, for example, a roll bar with, for example, glued-on bearing bushes can be pressed into a respective cavity in the form of the respective receiving opening 13, 14 of the integral support 2. The respective cover element 19, 20, which can be referred to as a closure plate, for example, can then be screwed on from above. This allows the required preload to be generated in the respective rubber bearing.Furthermore, the weight of the roll bar can be kept particularly low, for example, by removing the U-shaped clamp, reducing it by approximately 10 percent. In other words, the U-shaped clamp can be completely removed, for example, saving 10 percent of the weight of a front roll bar assembly.
