Technical Field

[0001] This application belongs to the field of automotive suspension equipment technology, specifically relating to a vehicle body assembly and the vehicle thereof. Background Technology

[0002] Generally speaking, suspension systems are mainly divided into two types: independent suspension and non-independent suspension. Independent suspensions mainly include MacPherson strut suspension, multi-link suspension, and double wishbone suspension, while non-independent suspensions commonly used include torsion beam structure and solid axle structure. However, current suspension systems have the problem of having many parts and taking up a lot of space. Utility Model Content

[0003] The purpose of this application is to provide a vehicle body assembly and vehicle thereof that not only reduces the number of suspension system components and space occupied, but also facilitates the connection between the main body and the frame and avoids stress concentration.

[0004] This application discloses a vehicle body assembly, including: a frame and a suspension system. The frame has intersecting first and second directions. The frame is provided with two mutually spaced-apart first mounting seats, a second mounting seat, a third mounting seat, and a fourth mounting seat. The two first mounting seats are arranged opposite each other along the first direction, and the two first mounting seats and the second mounting seat are arranged opposite each other along the second direction. The third mounting seat and the fourth mounting seat are located between the two first mounting seats and the second mounting seat. The suspension system includes two mutually spaced-apart rotating structures, a stabilizing structure, an elastic element, and a shock absorber. Each of the two rotating structures includes a main body and a rotating part connected to each other. One end of each rotating part away from the main body is rotatably connected to one of the two first mounting seats. The rotating part is curved. The stabilizing structure includes a stabilizing element and a connecting element. The stabilizing element is connected between the two main body parts. One end of the connecting element is rotatably connected to the stabilizing element, and the other end of the connecting element is rotatably connected to the second mounting seat. The elastic element is telescopically connected between the main body and the third mounting seat. The shock absorber is telescopically connected between the main body and the fourth mounting seat.

[0005] In one exemplary embodiment of this application, the rotating part includes a first rotating arm and a second rotating arm, one end of the second rotating arm is connected to the first rotating arm, the other end of the second rotating arm is connected to the main body, and the first rotating arm is rotatably connected to the first mounting base; wherein the second rotating arm is curved.

[0006] In one exemplary embodiment of this application, the rotating part further includes a sleeve assembly, which includes an outer sleeve, an inner sleeve, and a bushing. The inner sleeve is located inside the outer sleeve, and the bushing is connected between the outer sleeve and the inner sleeve. One end of the first rotating arm is connected to the outer sleeve, and the inner sleeve is rotatably connected to the first mounting base.

[0007] In one exemplary embodiment of this application, the main body includes a first beam, a second beam, a third beam, and a fourth beam. The first beam and the second beam are disposed opposite each other along the second direction, and the third beam and the fourth beam are disposed opposite each other along the first direction, and are all connected between the first beam and the second beam. The rotating part is connected to the first beam, the stabilizing member is connected between the two second beams, the elastic member is connected to the second beam, and the shock absorber is connected to the second beam.

[0008] In one exemplary embodiment of this application, a third beam of one main body portion is closer to a third beam of another main body portion relative to a fourth beam of the same main body portion; the elastic member is closer to the fourth beam relative to the third beam and is telescopically connected between the second beam and the third mounting base.

[0009] In an exemplary embodiment of this application, both the first beam and the second beam include a first side plate, a second side plate, a third side plate, and a fourth side plate. The first side plate and the second side plate are disposed opposite each other along a third direction, and the third side plate and the fourth side plate are disposed opposite each other along a second direction, and are both connected between the first side plate and the second side plate. The third beam and the fourth beam are connected between the fourth side plate of the first beam and the third side plate of the second beam. The rotating part is connected to the third side plate of the first beam. The stabilizing member is connected between the fourth side plates of the two second beams. The elastic member is connected to the first side plate of the second beam. The vibration damper is connected to the fourth side plate of the second beam. The third direction intersects both the first direction and the second direction.

[0010] In one exemplary embodiment of this application, the fourth side plate of the second beam is provided with a first mounting bracket and a second mounting bracket spaced apart from each other. The vibration damper is connected to the first mounting bracket by a fastener, and the stabilizer is connected to the second mounting bracket by the same fastener.

[0011] In one exemplary embodiment of this application, the suspension system further includes a brake mounting bracket, which includes a base plate and a vertical plate. The base plate is correspondingly disposed with respect to the fourth beam and connected between the first side plate of the first beam and the first side plate of the second beam. The vertical plate is connected to the side of the base plate away from the first beam and the second beam. The vertical plate is provided with a first mounting hole and a plurality of second mounting holes spaced apart from each other, and the plurality of second mounting holes are arranged around the first mounting holes.

[0012] In one exemplary embodiment of this application, both the first beam and the second beam include a support member, which is connected between the first side plate and the second side plate, and the support member is correspondingly disposed with the brake mounting bracket.

[0013] A second aspect of this application discloses a vehicle including a brake and the aforementioned body assembly, the brake being connected to the body assembly.

[0014] The proposed solution has the following beneficial effects:

[0015] In this embodiment, since the main body is connected to the rotating part, and the end of the rotating part away from the main body is rotatably connected to the first mounting seat of the frame, the rotating part and the main body can rotate synchronously relative to the frame. The main body can drive the elastic element to extend and retract between the main body and the third mounting seat of the frame, and the shock absorber to extend and retract between the main body and the fourth mounting seat of the frame. Simultaneously, the stabilizing element can adjust the movement of the two main bodies in opposite directions, thereby realizing the function of the suspension system. Furthermore, the suspension system is directly connected to the frame through the first, second, third, and fourth mounting seats, eliminating components such as the subframe and multi-link, thus reducing the number of components and the space occupied by the suspension system. At the same time, the rotating part is curved, and this curved structure avoids components such as the motor, facilitating the connection between the main body and the frame, and also preventing stress concentration.

[0032] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided to make this application more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art.

[0033] Furthermore, the described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a thorough understanding of embodiments of this application. However, those skilled in the art will recognize that the technical solutions of this application can be practiced without one or more of the specific details, or other methods, components, apparatuses, steps, etc., can be employed. In other instances, well-known methods, apparatuses, implementations, or operations are not shown or described in detail to avoid obscuring various aspects of this application.

[0034] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present application, and should not be construed as limiting the present application.

[0035] Combination Figures 1 to 2As shown, this embodiment provides a vehicle body assembly, including: a frame 1, the frame 1 having intersecting first direction x and second direction y, the frame 1 having two mutually spaced first mounting seats 17a, second mounting seats 17b, third mounting seats 17c and fourth mounting seats 17d, the two first mounting seats 17a being arranged opposite each other along the first direction x, the two first mounting seats 17a and the second mounting seat 17b being arranged opposite each other along the second direction y, and the third mounting seats 17c and the fourth mounting seats 17d being located between the two first mounting seats 17a and the second mounting seats 17b.

[0036] In this embodiment, the frame 1 includes a first longitudinal beam 11, a second longitudinal beam 12, a third longitudinal beam 13, a fourth longitudinal beam 14, a first crossbeam 15, and a second crossbeam 16. The first longitudinal beam 11 and the second longitudinal beam 12 are arranged opposite each other along a first direction x, and the first crossbeam 15 and the second crossbeam 16 are arranged opposite each other along a second direction y, and are both connected between the first longitudinal beam 11 and the second longitudinal beam 12. The third longitudinal beam 13 and the fourth longitudinal beam 14 are arranged opposite each other along the first direction x, and are both connected between the first crossbeam 15 and the second crossbeam 16.

[0037] It should be understood that the first direction x is the length direction of the first crossbeam 15, and the second direction y is the length direction of the first longitudinal beam 11.

[0038] In this embodiment, the frame 1 includes two second mounting seats 17b, two third mounting seats 17c, and two fourth mounting seats 17d arranged opposite each other along the first direction x. Both first mounting seats 17a are connected to the first crossbeam 15; both second mounting seats 17b are connected to the second crossbeam 16; one third mounting seat 17c is connected to the third longitudinal beam 13, and the other third mounting seat 17c is connected to the fourth longitudinal beam 14; one fourth mounting seat 17d is connected to both the second crossbeam 16 and the third longitudinal beam 13, and the other fourth mounting seat 17d is connected to both the second crossbeam 16 and the fourth longitudinal beam 14.

[0039] It should be understood that the two first mounting bases 17a are identical in shape and size and are symmetrically arranged, the two second mounting bases 17b are identical in shape and size and are symmetrically arranged, the two third mounting bases 17c are identical in shape and size and are symmetrically arranged, and the two fourth mounting bases 17d are identical in shape and size and are symmetrically arranged.

[0040] Furthermore, the vehicle body assembly also includes a suspension system 2, which includes two rotating structures 21 spaced apart from each other, a stabilizing structure 22, an elastic element 23, and a shock absorber 24. Each of the two rotating structures 21 includes a main body 211 and a rotating part 212 connected to each other. The ends of the two rotating parts 212 away from the main body 211 are rotatably connected to two first mounting seats 17a in a one-to-one correspondence. The rotating parts 212 are curved.

[0041] In this embodiment, each of the two first mounting seats 17a includes two first mounting portions arranged opposite each other along the first direction x, and each of the two rotating structures 21 includes two rotating portions 212. The two rotating portions 212 are connected to the same side of the main body 211, and the two rotating portions 212 are connected to the two first mounting portions one by one by two bolts. The two rotating portions 212 can increase the connection strength between the main body 211 and the frame 1.

[0042] In addition, the motor is located between the two rotating structures 21. The rotating part 212 is curved and bends away from the main body 211. The rotating part 212 can avoid the motor, which helps to increase the space for the motor and also avoids stress concentration.

[0043] Furthermore, the stabilizing structure 22 includes a stabilizing member 221 and a connecting member 222, which are U-shaped structures. The stabilizing member 221 is connected between the two main body parts 211. One end of the connecting member 222 is rotatably connected to the stabilizing member 221, and the other end of the connecting member 222 is rotatably connected to the second mounting base 17b. The elastic member 23 is telescopically connected between the main body part 211 and the third mounting base 17c. The shock absorber 24 is telescopically connected between the main body part 211 and the fourth mounting base 17d.

[0044] In this embodiment, the stabilizing structure 22 includes two connectors 222, which are connected to the two second mounting seats 17b one-to-one by two bolts. The two connectors 222 help to enhance the connection strength between the stabilizing component 221 and the frame 1. In addition, the body assembly includes two elastic members 23 and two shock absorbers 24. The two elastic members 23 are telescopically connected between the two third mounting seats 17c and the two main body parts 211, and the two shock absorbers 24 are telescopically connected between the two fourth mounting seats 17d and the two main body parts 211.

[0045] It should be understood that the two rotating structures 21 are identical in shape and size and are symmetrically arranged, the two connecting parts 222 are identical in shape and size and are symmetrically arranged, the two elastic parts 23 are identical in shape and size and are symmetrically arranged, and the two shock absorbers 24 are identical in shape and size and are symmetrically arranged.

[0046] In this embodiment, a mounting plate 3 is provided between the elastic member 23 and the third mounting base 17c, and a mounting plate 3 is provided between the elastic member 23 and the main body 211. The mounting plate 3 is used to install the elastic member 23. A mounting pad is provided between the mounting plate 3 and the elastic member 23. The mounting pad can buffer the impact brought by the elastic member 23 during the extension and retraction movement.

[0047] In addition, the ends of the elastic element 23 are reduced in diameter (usually referred to as "end tightening" or "closed end design"), which can reduce the stress concentration at the ends of the elastic element 23 during use, and at the same time improve the stability of the elastic element 23 and the ease of installation.

[0048] For example, the elastic element 23 can be in various forms such as an air spring or a coil spring.

[0049] In this embodiment, only a first mounting base 17a, a second mounting base 17b, a third mounting base 17c, a fourth mounting base 17d, a rotating structure 21, an elastic element 23, and a vibration damper 24 are described in detail below. Another first mounting base 17a, another second mounting base 17b, another third mounting base 17c, another fourth mounting base 17d, another rotating structure 21, another elastic element 23, and another vibration damper 24 can be implemented with reference to this description.

[0050] In this embodiment, since the main body 211 is connected to the rotating part 212, and the end of the rotating part 212 away from the main body 211 is rotatably connected to the first mounting seat 17a of the frame 1, the rotating part 212 and the main body 211 can rotate synchronously relative to the frame 1. The main body 211 can drive the elastic member 23 to extend and retract between the main body 211 and the third mounting seat 17c of the frame 1, and the shock absorber 24 to extend and retract between the main body 211 and the fourth mounting seat 17d of the frame 1. At the same time, the stabilizer 221 can adjust the movement of the two main bodies 211 in opposite directions, thereby realizing the function of the suspension system 2. Furthermore, the suspension system 2 is directly connected to the vehicle frame 1 via the first mounting bracket 17a, the second mounting bracket 17b, the third mounting bracket 17c, and the fourth mounting bracket 17d, eliminating components such as the subframe 1 and multi-link suspension to reduce the number of components in the suspension system 2 and the space occupied by the suspension system 2. At the same time, the rotating part 212 is curved, and the curved structure can avoid components such as the motor, so as to facilitate the connection between the main body 211 and the vehicle frame 1, and also avoid stress concentration.

[0051] Combination Figure 1 and Figure 8 As shown, the rotating part 212 includes a first rotating arm 2121 and a second rotating arm 2122. One end of the second rotating arm 2122 is connected to the first rotating arm 2121, and the other end of the second rotating arm 2122 is connected to the main body 211. The first rotating arm 2121 is rotatably connected to the first mounting base 17a. The second rotating arm 2122 is curved.

[0052] In this embodiment, since the second rotating arm 2122 is closer to the main body 211 than the first rotating arm 2121, it needs to be bent. The second rotating arm 2122 bends away from the main body 211. This bending design increases the space available for the motor and avoids stress concentration. Furthermore, since the first rotating arm 2121 is further away from the main body 211 than the second rotating arm 2122, it is designed as a straight line. Compared to a bent line, this reduces the connection length between the first rotating arm 2121, the second rotating arm 2122, and the first mounting base 17a, thereby reducing costs.

[0053] In other embodiments, both the first rotating arm 2121 and the second rotating arm 2122 may be configured to be curved.

[0054] In this embodiment, both the first rotating arm 2121 and the second rotating arm 2122 are circular tubes, eliminating the need for mold making for the first rotating arm 2121 and the second rotating arm 2122, which helps reduce development costs.

[0055] Combination Figure 1 , Figure 8 and Figure 9 As shown, the rotating part 212 also includes a sleeve assembly 2123, which includes an outer sleeve 2123a, an inner sleeve 2123b, and a bushing 2123c. The inner sleeve 2123b is located inside the outer sleeve 2123a, and the bushing 2123c is connected between the outer sleeve 2123a and the inner sleeve 2123b. One end of the first rotating arm 2121 is connected to the outer sleeve 2123a, and the inner sleeve 2123b is rotatably connected to the first mounting base 17a.

[0056] In this embodiment, when the rotating part 212 rotates relative to the first mounting base 17a, the bushing 2123c will be compressed and deformed. The bushing 2123c can provide a certain rotation space for the rotating part 212 to realize the rotation of the rotating part 212 relative to the first mounting base 17a. At the same time, the bushing 2123c also has the function of releasing stress and avoiding stress concentration in the rotating part 212.

[0057] In addition, the sleeve assembly 2123 is inclined relative to the first rotating arm 2121, that is, the distance between the sleeve assembly 2123 of one rotating structure 21 and the sleeve assembly 2123 of another rotating structure 21 gradually increases along the direction of the second rotating arm 2122 toward the first rotating arm 2121, which is beneficial to increase the arrangement space of the motor.

[0058] In this embodiment, both ends of the stabilizer 221 are also provided with sleeve assemblies 2123. The stabilizer 221 is connected to the outer sleeve 2123a, the inner sleeve 2123b is connected to the main body 211, and the bushing 2123c is connected between the outer sleeve 2123a and the inner sleeve 2123b. The end of the connector 222 connected to the second mounting base 17b is also provided with a sleeve assembly 2123. The connector 222 is connected to the outer sleeve 2123a, the inner sleeve 2123b is rotatably connected to the second mounting base 17b, and the bushing 2123c is connected between the outer sleeve 2123a and the inner sleeve 2123b. The end of the connector 222 connected to the stabilizer 221 is also provided with an outer sleeve 2123a and a bushing 2123c. The connector 222 is connected to the outer sleeve 2123a, and the bushing 2123c is connected between the connector 222 and the stabilizer 221.

[0059] It should be understood that the sleeve assembly 2123 provided in the stabilizer 221 and the connector 222 has the same structure as the sleeve assembly 2123 of the rotating part 212, but they are not the same sleeve assembly 2123.

[0060] Combination Figures 7 to 9 As shown, the main body 211 includes a first beam 211a, a second beam 211b, a third beam 211c, and a fourth beam 211d. The first beam 211a and the second beam 211b are arranged opposite each other along the second direction y, and the third beam 211c and the fourth beam 211d are arranged opposite each other along the first direction x, and are all connected between the first beam 211a and the second beam 211b. The second rotating arm 2122 is connected to the first beam 211a, the stabilizer 221 is connected between the two second beams 211b, the elastic member 23 is connected to the second beam 211b, and the shock absorber 24 is connected to the second beam 211b.

[0061] In this embodiment, the main body 211 has a "grid-shaped structure". The "grid-shaped structure" is beneficial to improving the rigidity of the main body 211, so that the main body 211 has higher stability when it rotates relative to the frame 1 with the rotating part 212, thereby improving the stability of the suspension system 2.

[0062] In addition, the first beam 211a, the second beam 211b, the third beam 211c, and the fourth beam 211d are all square tubes, eliminating the need for mold making for the first beam 211a, the second beam 211b, the third beam 211c, and the fourth beam 211d, which helps reduce development costs.

[0063] In this embodiment, combined with Figure 1 , Figure 7 and Figure 9As shown, the third beam 211c of one main body 211 is closer to the third beam 211c of another main body 211 than the fourth beam 211d of the same main body 211; the elastic member 23 is closer to the fourth beam 211d than the third beam 211c, and is telescopically connected between the second beam 211b and the third mounting base 17c. The closer the elastic member 23 is to the fourth beam 211d than the third beam 211c increases the distance between the two elastic members 23 along the first direction x, thereby increasing the space available for the motor and facilitating its installation.

[0064] Combination Figure 9 As shown, both the first beam 211a and the second beam 211b include a first side plate a, a second side plate b, a third side plate c, and a fourth side plate d. The first side plate a and the second side plate b are arranged opposite each other along the third direction z, and the third side plate c and the fourth side plate d are arranged opposite each other along the second direction y, and are both connected between the first side plate a and the second side plate b. The third beam 211c and the fourth beam 211d are connected between the fourth side plate d of the first beam 211a and the third side plate c of the second beam 211b. The second rotating arm 2122 is connected to the third side plate c of the first beam 211a. The stabilizer 221 is connected between the fourth side plates d of the two second beams 211b. The elastic member 23 is connected to the first side plate a of the second beam 211b. The damper 24 is connected to the fourth side plate d of the second beam 211b. The third direction z intersects with both the first direction x and the second direction y.

[0065] In this embodiment, the third direction z is the direction from the frame 1 toward the main body 211. The second rotating arm 2122 is connected to the third side plate c of the first beam 211a, the stabilizer 221 is connected between the fourth side plates d of the two second beams 211b, and the shock absorber 24 is connected to the fourth side plate d of the second beam 211b. The rotating part 212, the stabilizer 221, and the shock absorber 24 are arranged on the two side plates of the main body 211 along the second direction y, which helps to reduce the space occupied by the rotating part 212, the stabilizer 221, and the shock absorber 24 for the motor arrangement, thereby improving the space utilization rate.

[0066] It should be understood that the first direction x, the second direction y, and the third direction z are all bidirectional.

[0067] Combination Figures 7 to 9 As shown, the fourth side plate d of the second beam 211b is provided with a first mounting bracket 213 and a second mounting bracket 214 spaced apart from each other. The vibration damper 24 is connected to the first mounting bracket 213 by fasteners, and the stabilizer 221 is connected to the second mounting bracket 214 by the same fasteners.

[0068] In this embodiment, the vibration damper 24 and the stabilizer 221 are connected to the fourth side plate d of the second beam 211b by the same fastener. This not only facilitates the installation of the vibration damper 24 and the stabilizer 221 and improves installation efficiency, but also reduces the number of parts and the space occupied, which helps to improve space utilization.

[0069] In addition, the end of the damper 24 away from the second beam 211b is connected to the fourth mounting base 17d by two bolts.

[0070] For example, fasteners can be bolts, screws, etc.

[0071] Combination Figure 5 , Figure 11 and Figure 12 As shown, the suspension system 2 also includes a brake mounting bracket 25, which includes an integral base plate 251 and a vertical plate 252. The base plate 251 is correspondingly arranged with the fourth beam 211d and connected between the first side plate a of the first beam 211a and the first side plate a of the second beam 211b. The vertical plate 252 is connected to the side of the base plate 251 away from the first beam 211a and the second beam 211b. The vertical plate 252 is provided with mutually spaced first mounting holes 201 and a plurality of second mounting holes 202, and the plurality of second mounting holes 202 are arranged around the first mounting holes 201.

[0072] In this embodiment, the base plate 251 has four identical third mounting holes 203. Two bolts pass through two of the third mounting holes 203 and connect to the first side plate a of the first beam 211a. Two bolts pass through the other two third mounting holes 203 and connect to the first side plate a of the second beam 211b. Simultaneously, the base plate 251 and the fourth beam 211d are in contact along the third direction z, which enhances the installation strength of the brake mounting bracket 25 and ensures the stability of the brake installation. Furthermore, the upright plate 252 is located along the second direction y between the two third mounting holes 203 and the other two third mounting holes 203. The upright plate 252's placement among the four third mounting holes 203 also enhances the installation strength of the brake mounting bracket 25 and ensures the stability of the brake installation.

[0073] In this embodiment, the upright plate 252 is provided with a first mounting hole 201 and four second mounting holes 202. The first mounting hole 201 is used to install the drive shaft, which passes through the first mounting hole 201. The four second mounting holes 202 are used to install the brake disc. Four bolts are inserted one by one into the four second mounting holes 202 and connected to the brake disc, thereby installing the wheel onto the brake disc.

[0074] In addition, a boss 253 is provided on the side of the upright plate 252 away from the third beam 211c. The boss 253 protrudes relative to the upright plate 252. The end face e of the boss 253 needs to be precision machined on a machine tool to ensure the flatness and roughness of the end face e, thereby ensuring the accuracy of the toe angle and camber angle set by the whole vehicle after the brake is installed.

[0075] Combination Figure 8 and Figure 9 As shown, both the first beam 211a and the second beam 211b include a support member 215. The support member 215 is connected between the first side plate a and the second side plate b. The support member 215 is correspondingly arranged with the brake mounting bracket 25.

[0076] In this embodiment, both the first beam 211a and the second beam 211b include two support members 215. The first side plate a of the first beam 211a is provided with two first through holes 204, and the two first through holes 204 are corresponding to the two support members 215 in the first beam 211a. The first side plate a of the second beam 211b is provided with two second through holes 205, and the two second through holes 205 are corresponding to the two support members 215 in the second beam 211b. The two first through holes 204 and the two second through holes 205 are corresponding to the four third mounting holes 203.

[0077] In this embodiment, when the brake mounting bracket 25 is connected to the first beam 211a and the second beam 211b, two bolts pass through the two third mounting holes 203, the two first through holes 204, and the two support members 215 in the first beam 211a, respectively. Similarly, two bolts pass through the other two third mounting holes 203, the two second through holes 205, and the two support members 215 in the second beam 211b, respectively. The support members 215 support the first side plate a and the second side plate b, preventing deformation of the first beam 211a and the second beam 211b. Simultaneously, the bolts passing through the support members 215 also limit the installation of the bolts, ensuring the stability of the connection between the brake mounting bracket 25 and the first beam 211a and the second beam 211b.

[0078] For example, support member 215 can be a support sleeve, support block, or the like.

[0079] In this embodiment, a support sleeve is provided between the first mounting bracket 213 and the second mounting bracket 214. The support sleeve is connected between the first mounting bracket 213 and the second mounting bracket 214. When the stabilizer 221 and the damper 24 are connected to the fourth side plate d of the second beam 211b, a bolt will pass through the support sleeve. The support sleeve can provide a certain support for the first mounting bracket 213 and the second mounting bracket 214.

[0080] In this embodiment, after the suspension system 2 is connected to the vehicle frame 1, the brake is first installed on the upright plate 252 of the brake mounting bracket 25, and then the wheel is installed on the brake. During vehicle operation, the torque generated by the wheel is transmitted to the rotating structure 21 through the brake mounting bracket 25. The rotating part rotates relative to the vehicle frame 1 around the axis of the first mounting seat 17a, and drives the dynamic stretching and compression of the elastic element 23 and the shock absorber 24. At the same time, the stabilizer 221 performs reverse adjustment of the first direction x-roll torque, thereby realizing the function of the suspension system 2.

[0081] In this embodiment, the suspension system 2 can be applied not only to four-wheeled vehicles, but also to commercial vehicles and heavy trucks, including three-axle (six tires) and four-axle (six tires) vehicles.

[0082] In other embodiments, the suspension system 2 may be connected to a monocoque vehicle body.

[0083] It should be understood that the length of the stabilizer 221 along the first direction x can be adjusted according to the different wheel track sizes of different vehicles to improve the matching of the suspension system 2.

[0084] This embodiment also provides a vehicle, including a brake and the aforementioned body assembly, with the brake connected to the body assembly.
