[0043] It should be noted that with the rapid development of new energy vehicles, the weight of the vehicle is increasing and the space for chassis layout is decreasing, which puts forward higher performance requirements for the suspension system. Among them, the control arm, as an important part of the suspension system, directly affects the performance of the suspension system due to its design quality.

[0044] In related technologies, in order to improve the performance of the suspension system, some models adopt multi-link suspension. Among them, the control arm, as the main guiding and force transmission mechanism of the multi-link suspension, needs to withstand large torque and load. However, at present, the control arm structure usually uses bushings as load-bearing components in the vehicle height direction, resulting in insufficient overall load-bearing capacity of the control arm structure, which makes it difficult to meet the load-bearing requirements of new energy vehicles.

[0045] Based on this, this application proposes a control arm assembly 100. Through the coordinated use of the first cross arm 11, the second cross arm 12, and the support frame 2, the control arm assembly 100 integrates the load-bearing capacity in the vehicle height direction, length direction, and width direction, simplifying the structural design of the control arm assembly 100. At the same time, the first mounting part 111 and the third mounting part 21 are equivalent to a two-force bar, and the second mounting part 121 and the third mounting part 21 are equivalent to a two-force bar, thereby realizing a three-point composite structural design of the control arm assembly 100. This is beneficial to improving the stability and reliability of the control arm assembly 100, thereby improving the load-bearing capacity of the control arm assembly 100.

[0046] like Figures 1-4 As shown, the control arm assembly 100 according to the first aspect of this application includes: a control arm body 1 and a support frame 2.

[0047] Specifically, as shown in Figure 1 the control arm assembly 100 is applied to the suspension system of the vehicle, wherein the control arm body 1 in the control arm assembly 100 comprises a first transverse arm 11, a second transverse arm 12 and a connecting piece 13, it should be noted that the first transverse arm 11 and the second transverse arm 12 are arranged along the width direction of the vehicle, for example, the first transverse arm 11 and the second transverse arm 12 can extend along the width direction of the vehicle, or the extension direction of the first transverse arm 11 and the second transverse arm 12 is at a certain angle with the width direction of the vehicle, further, along the length direction X of the vehicle, the first transverse arm 11 and the second transverse arm 12 are oppositely arranged and spaced apart, and the connecting piece 13 is fixedly connected between the first transverse arm 11 and the second transverse arm 12, for example, the first transverse arm 11, the second transverse arm 12 and the connecting piece 13 can constitute a U-shaped control arm body 1, in this way, the installation of the subframe 200 can be provided with a clearance space to avoid interference during assembly.

[0048] Further, the first transverse arm 11 has a first mounting portion 111 fixedly connected with the subframe 200 of the vehicle at one end away from the connecting piece 13, and the second transverse arm 12 has a second mounting portion 121 fixedly connected with the subframe 200 of the vehicle at one end away from the connecting piece 13, that is, the first transverse arm 11 is fixedly connected with the subframe 200 through the first mounting portion 111, and the second transverse arm 12 is fixedly connected with the subframe 200 through the second mounting portion 121, in this way, since the first transverse arm 11 and the second transverse arm 12 are arranged along the width direction of the vehicle, the first transverse arm 11 and the second transverse arm 12 can bear the force transmitted by the subframe 200 along the width direction of the vehicle, at the same time, since the first transverse arm 11 and the second transverse arm 12 fix the subframe 200 along the length direction X of the vehicle, the force and torque transmitted by the subframe 200 along the length direction X of the vehicle can be borne, that is, the integration of the control arm body 1 in the length direction and the width direction of the vehicle to bear the force is realized.

[0049] Further, the support frame 2 is fixedly installed on the connecting piece 13, and the support frame 2 has a third mounting portion 21 at one end away from the connecting piece 13, the third mounting portion 21 is fixedly connected with the hub bracket 300 of the vehicle, and the support frame 2 extends upward along the height direction Y of the vehicle to support the hub bracket 300 in the height direction Y of the vehicle. In order for the control arm assembly 100 to be arranged in the Figure 2The shown arrangement direction is used as an example for illustration, the support frame 2 supports the hub support 300 upward in the height direction Y of the vehicle, wherein the support frame 2 can extend upward in the height direction Y of the vehicle, or the upward extension direction of the support frame 2 can be provided with a certain angle with the height direction Y of the vehicle, as long as the support frame 2 can support the hub support 300 upward in the height direction Y of the vehicle. By supporting the hub support 300 in the height direction Y of the vehicle through the support frame 2, the control arm assembly 100 can bear the force transmitted by the vehicle body in the height direction Y of the vehicle, thereby realizing the integration of the bearing capacity of the control arm assembly 100 in the height direction, length direction and width direction of the vehicle. Compared with the traditional method of bearing force by setting multiple control arms, the number of parts is reduced, the structure of the control arm assembly 100 is simplified, the structure of the control arm assembly 100 is simpler, which is conducive to saving cost. At the same time, compared with the traditional flexible support of the bushing, the support frame 2 is a rigid support, which is conducive to improving the bearing capacity of the control arm assembly 100 in the height direction of the vehicle.

[0050] It should be noted that in some embodiments of the present application, the control arm assembly 100 is configured as a three-point composite structure design, wherein the first mounting portion 111 and the third mounting portion 21 of the control arm assembly 100 form a two-force lever structure, and similarly, the second mounting portion 121 and the third mounting portion 21 of the control arm assembly 100 also form a two-force lever structure, that is, through the cooperation of the first mounting portion 111, the second mounting portion 121 and the third mounting portion 21, two two-force lever structures are formed. In this way, the anti-deformation ability of the control arm assembly 100 when subjected to force is stronger, so as to be able to bear greater force, which is conducive to improving the stability and reliability of the control arm assembly 100, and further improving the bearing capacity of the control arm assembly 100 to meet the use requirements of new energy vehicles with heavier weight.

[0051] According to the control arm assembly 100 provided by the first aspect of the present application, the cooperation of the first transverse arm 11, the second transverse arm 12 and the support frame 2 realizes the integration of the bearing capacity of the control arm assembly 100 in the height direction, length direction and width direction of the vehicle, and simplifies the structural design of the control arm assembly 100. At the same time, the first mounting portion 111 and the third mounting portion 21 are equivalent to a two-force lever, and the second mounting portion 121 and the third mounting portion 21 are equivalent to a two-force lever, thereby realizing the three-point composite structure design of the control arm assembly 100. This is conducive to improving the stability and reliability of the control arm assembly 100, and further improving the bearing capacity of the control arm assembly 100.

[0052] In some embodiments of the present application, the first mounting portion 111 and the second mounting portion 121 of the control arm body 1 are fixedly connected with the subframe 200 through the bushings, and the third mounting portion 21 of the support frame 2 is fixedly connected with the hub bracket 300 through the bushing. In this way, the bushing as a flexible kinetic energy absorbing member can absorb the impact force between the control arm and the subframe 200 and the hub bracket 300, which is conducive to improving the stability of the suspension system.

[0053] In some embodiments of the present application, the control arm body 1 needs to bear large transverse forces and moments, so the control arm body can be made of bar material, pipe material or stamped sheet metal material, which simplifies the production process and reduces the production cost.

[0054] In some embodiments of the present application, as shown in Figures 2-4 The control arm assembly 100 further includes a support plate 3 fixedly connected with the support frame 2 and the control arm body 1.

[0055] Specifically, one part of the support plate 3 is fixedly connected with the support frame 2, and the other part is fixedly connected with the control arm body 1. The fixed connection mode of the support plate 3 includes but is not limited to welding. In this way, a reinforcing plate is connected between the support frame 2 and the control arm body 1, thereby improving the connection strength between the support frame 2 and the control arm body 1, and further improving the overall strength and rigidity of the control arm assembly 100, which is conducive to further improving the load capacity of the control arm assembly 100.

[0056] In some embodiments of the present application, the support plate 3 and the support frame 2 jointly form a first mounting cavity.

[0057] Specifically, the support frame 2 includes a first connecting plate, a second connecting plate and a third connecting plate. Along the length direction X of the vehicle, the first connecting plate and the third connecting plate are oppositely arranged and spaced apart, and the second connecting plate is connected between the first connecting plate and the third connecting plate. Further, part of the support plate 3 is oppositely arranged with the second connecting plate, and the support plate 3 is fixedly connected with the first connecting plate and the third connecting plate. The first connecting plate, the second connecting plate, the third connecting plate and the support plate 3 jointly form the first mounting cavity. In this way, while meeting the support capacity of the support frame 2, the first mounting cavity can also reduce the weight of the support frame 2, which is conducive to reducing the weight of the control arm assembly 100 and thereby improving the lightweight level of the vehicle.

[0058] It should be noted that the support frame 2 can also be provided with other structures, such as a cylindrical hollow structure formed by the support plate 3 and the support frame 2, and the like, which are specifically set according to actual conditions and will not be illustrated one by one here.

[0059] In some embodiments of the present application, as shown in Figures 2-4As shown, the support plate 3 includes a first mounting plate 31 and a second mounting plate 32 connected together, the first mounting plate 31 is fixedly connected with the support frame 2 and forms a first mounting cavity together, and the second mounting plate 32 is fixedly connected with the connecting piece 13, and part of the outer surface of the connecting piece 13 is covered by the second mounting plate 32.

[0060] Specifically, the control arm assembly 100 is arranged in the following manner: Figure 2 As an example, the support plate 3 includes a first mounting plate 31 and a second mounting plate 32 connected together, the first mounting plate 31 is arranged above the second mounting plate 32, wherein the first mounting plate 31 can extend upward along the height direction Y of the vehicle, or the upward extension direction of the first mounting plate 31 can be arranged at an angle with the height direction Y of the vehicle, further, the first mounting plate 31 is fixedly connected with the support frame 2, for example, assuming that the support frame 2 includes a first connecting plate, a second connecting plate and a third connecting plate, wherein along the length direction X of the vehicle, the first connecting plate and the third connecting plate are oppositely arranged and spaced apart, and the second connecting plate is connected between the first connecting plate and the third connecting plate, further, the first mounting plate 31 is oppositely arranged with the second connecting plate, and the first mounting plate 31 is fixedly connected with the first connecting plate and the third connecting plate, so that the first connecting plate, the second connecting plate, the third connecting plate and the first mounting plate 31 form a first mounting cavity together, thereby reducing the weight of the support frame 2.

[0061] The second mounting plate 32 is fixedly connected with the connecting piece 13, and part of the outer surface of the connecting piece 13 is covered by the second mounting plate 32, for example, assuming that the connecting piece 13 is configured as a circular pipe, then part of the structure of the second mounting plate 32 is configured as an arc plate that is fitted with the outer surface of the circular pipe, so that the arc plate can cover part of the outer surface of the connecting piece 13, further, the connection manner of the second mounting plate 32 and the connecting piece 13 includes but is not limited to welding, in this way, the contact area of the second mounting plate 32 and the connecting piece 13 can be increased, thereby facilitating to reduce the load at the connection between the second mounting plate 32 and the connecting piece 13, and facilitating to improve the connection strength between the support plate 3 and the support frame 2, thereby reducing the risk of cracking at the connection between the support plate 3 and the support frame 2 due to stress concentration, and further improving the overall strength and rigidity of the control arm assembly 100.

[0062] It should be noted that the covering of the second mounting plate 32 on the connecting piece 13 is arranged according to the specific shape of the connecting piece 13, for example, if the connecting piece 13 is configured as a hollow pipe with a rectangular cross section, then the covering structure of the second mounting plate 32 can be correspondingly arranged as a bending plate that is fitted therewith, which is arranged according to the actual situation, and will not be illustrated one by one here.

[0063] In some embodiments of the present application, as Figures 2-4As shown, the second mounting plate 32 has a flange 321, which is located below the support frame 2 in the height direction Y of the vehicle and is fixedly connected with the support frame 2. That is, the flange 321 structure connected with the support frame 2 is also arranged below the support frame 2, and the flange 321 is fixedly connected with the support frame 2, which can not only support the support frame 2 from below to support the support frame 2, but also can increase the area of the connection region between the support plate 3 and the support frame 2, thereby further improving the connection strength between the two.

[0064] In some embodiments of the present application, as shown in Figures 2-4 As shown, the control arm assembly 100 further comprises a mounting seat 4 located on the side of the first mounting plate 31 away from the support frame 2, and part of the mounting seat 4 is fixedly connected with the first mounting plate 31. The mounting seat 4 is used for fixedly mounting a buffer block 5 which is adapted to abut against the frame of the vehicle when the hub bracket 300 jumps in the height direction Y of the vehicle.

[0065] Specifically, the control arm assembly 100 further integrally arranges a buffer block 5 mounting point, and the buffer block 5 is mounted on the mounting seat 4. During vehicle driving, the road excitation received by the wheel will jump upward in the height direction Y of the vehicle, thereby driving the hub bracket 300 to jump upward, so that the control arm assembly 100 as a whole moves upward. When the upward jumping height of the wheel is large, the buffer block 5 abuts against the frame of the vehicle. This can not only generate a buffer between the control arm assembly 100 and the frame, thereby reducing the vibration of the frame and improving the buffering capacity of the suspension system, but also has a certain limiting effect after the buffer block 5 is compressed, so as to prevent the wheel from jumping too high and causing large bumps.

[0066] It should be noted that the mounting seat 4 is located on the side of the first mounting plate 31 away from the support frame 2, and part of the mounting seat 4 is fixedly connected with the first mounting plate 31, and the other part is fixedly connected with the second mounting plate 32. That is, the mounting seat 4 is borne by the support plate 3, so that the force borne by the mounting seat 4 is dispersed to the support plate 3, which is beneficial to reduce stress concentration and reduce the risk of the mounting seat 4 falling off.

[0067] In some embodiments of the present application, as shown in Figure 4 As shown, the mounting seat 4 and the support frame 2 jointly form a second mounting cavity 41. That is, the mounting seat 4 can jointly form the second mounting cavity 41 with the support plate 3. By arranging the second mounting cavity 41, the weight of the mounting seat 4 can be reduced while ensuring the support strength, thereby being beneficial to reduce the weight of the control arm assembly 100 and further being beneficial to improve the light weight level of the vehicle.

[0068] In some embodiments of the present application, as shown in Figure 3As shown in FIG. 1 and FIG. 2, the mounting seat 4 has a mounting plane 42, the buffer block 5 is fixedly arranged on the mounting plane 42, the mounting plane 42 extends along the length direction X of the vehicle, and the mounting plane 42 is below a first horizontal plane and forms a first included angle with the first horizontal plane, and the first included angle is 15°-20°. The mounting plane 42 and the first mounting plate 31 form an intersection line extending along the length direction X of the vehicle, and the first horizontal plane passes through the intersection line horizontally.

[0069] Specifically, the mounting seat 4 is fixedly connected with the first mounting plate 31, and the mounting plane 42 extends along the length direction X of the vehicle. In this way, the mounting plane 42 and the first mounting plate 31 can form an intersection line extending along the length direction X of the vehicle. It can be understood that the intersection line of the mounting plane 42 and the first mounting plate 31 is the connecting line of the two. In some embodiments of the present application, the first horizontal plane passes through the intersection line horizontally. It can be understood that there are many horizontal planes along the height direction Y of the vehicle, but the first horizontal plane is the horizontal plane that passes through the intersection line horizontally, that is, the first horizontal plane intersects with the intersection line of the mounting plane 42. Further, along the height direction Y of the vehicle, the mounting plane 42 is below the first horizontal plane and forms a first included angle with the first horizontal plane. The first included angle can be 15°, 16°, 17°, 18°, 19°, or 20°, and is specifically set according to actual needs. The buffer block 5 is fixedly arranged on the mounting plane 42. In this way, when the buffer block 5 abuts against the frame of the vehicle, the mounting seat 4 can not only bear the load and impact force from the height direction Y of the vehicle, but also balance the force from the width direction of the vehicle and the torque from the length direction X of the vehicle that the control arm assembly 100 receives, thereby improving the load-bearing performance of the control arm assembly 100.

[0070] In some embodiments of the present application, the mounting plane 42 can be provided with a reinforcing rib or a reinforcing groove. In this way, the rigidity and load-bearing performance of the mounting seat 4 can be further improved.

[0071] In some embodiments of the present application, as shown in FIG. 1 and FIG. 2, Figure 2 and Figure 3 along the height direction Y of the vehicle, the first mounting plate 31 has a first end and a second end, wherein the second end is closer to the connecting piece 13 than the first end, and the size of the first mounting plate 31 in the length direction X of the vehicle gradually increases from the first end to the second end.

[0072] Specifically, along the height direction Y of the vehicle, the first end of the first mounting plate 31 is located above the second end, when the force acting on the mounting seat 4 acts on the first mounting plate 31, the first mounting plate 31 bears the force of the mounting seat 4 along the height direction Y of the vehicle, and since the size (length) of the first mounting plate 31 in the length direction X of the vehicle gradually increases from the first end to the second end, it is beneficial to further disperse the force of the mounting seat 4 to the control arm body 1 through the first mounting plate 31, thereby improving the support effect on the mounting seat 4.

[0073] In a second aspect, the embodiment of the present application provides a suspension system including the control arm assembly 100 in the first aspect.
