Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a lower control arm assembly, a suspension structure and a vehicle. Background Art

[0002] In the body structure of a vehicle, the frame and the wheels are usually connected by a suspension. During the driving of the vehicle, the suspension can transfer the force exerted by the road surface on the wheels to the frame, so that the vehicle can drive normally.

[0021] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0023] At present, the suspension structure of a vehicle usually adopts a lower swing arm structure in which two swing arms are connected at a certain angle to connect the frame and the wheel. The connection angle of the two swing arms is fixed. When subjected to forces in different directions of the wheels, the lower swing arm structure with a completely rigid structure cannot decouple the forces of the wheels, that is, the direction of the wheel forces cannot be decomposed. The bushings connecting the two swing arms to the frame will also be subjected to radial force and axial force at the same time. Forces in different directions have different effects on the vehicle's handling and comfort. Therefore, the bushings cannot coordinate the vehicle's handling and comfort.

[0024] like Figures 1 to 3As shown, an embodiment of the present application provides a lower swing arm assembly, wherein the lower swing arm assembly 10 includes a first connecting arm 11 and a second connecting arm 12, the first connecting arm 11 is used to connect the steering knuckle 30 and the subframe 20 of the suspension structure, the first connecting arm 11 has a first connecting portion 111 and a first bushing 113, at least a portion of the first connecting portion 111 is movably arranged, the first bushing 113 is arranged at the end of the first connecting arm 11, the first connecting arm 11 can be rotatably connected to the subframe 20 through the first bushing 113, one end of the second connecting arm 12 has a second bushing 121, the second connecting arm 12 is rotatably connected to the subframe 20 through the second bushing 121, and the other end of the second connecting arm 12 is movably connected to the first connecting arm 11 through the first connecting portion 111.

[0025] In a specific implementation, the lower swing arm assembly 10 of the embodiment of the present application includes a first connecting arm 11 and a second connecting arm 12. The lower swing arm assembly 10 is connected between the steering knuckle 30 and the subframe 20 of the suspension structure through the first connecting arm 11. The first connecting arm 11 and the second connecting arm 12 are rotatably connected to different positions of the subframe 20 through the first bushing 113 and the second bushing 121 respectively. The other end of the second connecting arm 12 is movably connected to the first connecting arm 11 through the first connecting portion 111. During the driving process of the vehicle, the wheels will apply forces in different directions to the steering knuckle 30, and the steering knuckle 30 will transmit the forces to the first connecting arm 11. Since the second connecting arm 12 is connected to the first connecting arm 11 The second connecting arm 12 is movably connected through the first connecting portion 111, so both ends of the second connecting arm 12 are movably connected, which is equivalent to a two-force rod, so that the second connecting arm 12 is only subjected to the force along its extension direction, and the second bushing 121 connected thereto is also only subjected to the radial force in the extension direction of the second connecting arm 12, and will not be subjected to the vertical axial force. Since the first connecting arm 11 has at least three connection points, the first bushing 113 connected thereto is subjected to both radial force and axial force. Therefore, the radial force and axial force can be distributed through the first bushing 113 and the second bushing 121, thereby completing the decoupling of the wheel force, optimizing the lateral support and longitudinal flexibility of the wheel, and coordinating the vehicle's handling and comfort.

[0026] Specifically, the first bushing 113 and the second bushing 121 are both bushing structures, and the first connecting arm 11 and the second connecting arm 12 can be rotatably connected to the subframe 20 through the bushing structure. The bushing structure has an annular structure, and a rod-shaped connecting structure is inserted inside the annular structure. The rod-shaped structure is rotatably arranged inside the annular structure for connecting the annular structure and other connecting parts. In an embodiment of the present application, one end of the rod-shaped structure is connected to the subframe 20, and the other end is arranged in the annular structure. The outer peripheral surface of the annular structure is connected to the end of the first connecting arm 11 or the second connecting arm 12, so the force transmitted to the second bushing 121 along the extension direction of the second connecting arm 12 is a radial force.

[0027] like Figures 1 to 3 As shown, the lower swing arm assembly of the embodiment of the present application, wherein the first connecting arm 11 also includes a second connecting portion 112, at least a portion of the second connecting portion 112 is movably arranged, and the first connecting arm 11 is movably connected to the steering knuckle 30 through the second connecting portion 112.

[0028] In specific implementation, when the wheel applies a force to the steering knuckle 30, the force will act on the connection between the steering knuckle 30 and the first connecting arm 11 through the steering knuckle 30. The first connecting arm 11 is movably connected to the steering knuckle 30 through the second connecting portion 112, which can effectively weaken the force at the connection between the first connecting arm 11 and the steering knuckle 30, transform the rigid force, reduce the damage at the second connecting portion 112, and improve the overall strength of the lower control arm assembly 10.

[0029] like Figures 1 to 3 As shown, the lower swing arm assembly of the embodiment of the present application, wherein the first connecting portion 111 and the second connecting portion 112 are arranged to be spaced apart along the extension direction of the first connecting arm 11 , and the second connecting portion 112 is connected to the end of the steering knuckle 30 .

[0030] In specific implementation, during the driving of the vehicle, the steering knuckle 30 will swing, and the first connecting part 111 and the second connecting part 112 are spaced apart at different positions of the first connecting arm 11 to avoid the first connecting part 111 being connected to the steering knuckle 30, so that the rotation center of the first connecting part 111 is fixedly set on the first connecting arm 11 and will not swing. If connected to the steering knuckle 30, the first connecting part 111 will swing with the steering knuckle 30. Therefore, when the vehicle is turning, the lower swing arm assembly 10 as a whole still maintains a relatively stable state, and its steering performance will not change due to the separate setting of the first connecting arm 11 and the second connecting arm 12.

[0031] like Figures 1 to 3 As shown, the lower control arm assembly of the embodiment of the present application, wherein the first connecting arm 11 and the second connecting arm 12 are connected at a preset angle, and in the extension direction of the sub-frame 20, the first bushing 113 is installed at a position of the sub-frame 20 close to the wheel center of the vehicle, and the second bushing 121 is installed at a position of the sub-frame 20 away from the wheel center of the vehicle.

[0032] In specific implementation, in the extension direction of the subframe 20, the first bushing 113 is installed at a position of the subframe 20 close to the wheel center of the vehicle, and the second bushing 121 is installed at a position of the subframe 20 away from the wheel center of the vehicle. In this way, support can be achieved for both the center position and the edge position of the wheel, thereby ensuring support stability and making the vehicle more stable when turning.

[0033] Specifically, the first connecting arm 11 is connected between the sub-frame 20 and the steering knuckle 30 along the left-right direction when the vehicle is traveling, and mainly plays a load-bearing role, and can bear the force when the vehicle turns; the second connecting arm 12 is obliquely connected between the sub-frame 20 and the steering knuckle 30, and mainly plays a guiding role when the vehicle turns, and can bear part of the force, thereby ensuring the accuracy of the vehicle steering.

[0034] like Figures 1 to 3 As shown, the lower swing arm assembly of the embodiment of the present application, wherein, along a direction perpendicular to the first connecting arm 11, the second connecting arm 12 is connected to the lower side of the first connecting arm 11 through the first connecting portion 111, the second connecting arm 12 includes an avoidance portion 122 connected to the first connecting portion 111 and an extension portion 123 connected to the second bushing 121, the avoidance portion 122 is a bent rod section, used for avoiding the first connecting arm 11, and the extension portion 123 is connected between the subframe 20 and the avoidance portion 122.

[0035] In a specific implementation, the second connecting arm 12 avoids the first connecting arm 11 through the curved avoidance portion 122, so that it can pass under the first connecting arm 11, and the second connecting arm 12 can be connected to the sub-frame 20 and the avoidance portion 122 through the extension portion 123, so that the second connecting arm 12 can pass over the first connecting arm 11 and be connected to any position of the sub-frame 20 without being restricted by the curved structure of the avoidance portion 122, thereby solving the problem that the split lower swing arm assembly 10 can only connect the second connecting arm 12 to one side of the first connecting arm 11, that is, solving the problem of the need to place the second connecting arm 12 in front.

[0036] Optionally, the extension portion 123 may be a straight rod segment or a curved rod segment, and may be designed according to the shape of the avoidance portion 122 and the connection position of the extension portion 123 .

[0037] like Figures 1 to 3 As shown, the lower swing arm assembly of the embodiment of the present application, wherein the first connecting arm 11 also has a third connecting portion 114, the third connecting portion 114 passes through the first connecting arm 11 and is rotatably arranged, and the first connecting arm 11 is rotatably connected to the shock absorber assembly 40 of the suspension structure through the third connecting portion 114.

[0038] In a specific implementation, the third connecting portion 114 passes through the first connecting arm 11 and is rotatably arranged, so that the shock absorber assembly 40 of the suspension structure can be rotatably connected to both sides of the first connecting arm 11, thereby ensuring the connection stability between the shock absorber assembly 40 and the first connecting arm 11, and at the same time enabling the shock absorber assembly 40 to be rotatably connected to the first connecting arm 11. When the shock absorber assembly 40 is subjected to an impact, it can rotate slightly, thereby achieving the effect of buffering the impact.

[0039] like Figure 2As shown, the lower arm assembly of the first embodiment of the present application, wherein the first connecting part 111 and the second connecting part 112 are both ball head structures, the ball head structure includes a fixedly connected ball head pin and a connecting rod 115, the ball head pin is rotatably connected to the first connecting arm 11 along its spherical surface, and the connecting rod 115 is detachably connected to the second connecting arm 12 or the steering knuckle 30.

[0040] In specific implementation, the first connection part 111 and the second connection part 112 adopt a ball head structure. The ball head pin of the ball head structure is a spherical structure, which can rotate in all directions along its own spherical surface. When the steering knuckle 30 moves in any direction, the first connection part 111 and the second connection part 112 can swing in the same direction, thereby minimizing the impact force of the wheel on the subframe 20 and improving the overall stability of the suspension structure.

[0041] In the lower swing arm assembly of the second embodiment of the present application, the first connecting portion 111 is a bushing structure, and the second connecting portion 112 is a ball head structure. Along the axial direction of the bushing structure, the first connecting arm 11 is rotatably connected to the second connecting arm 12.

[0042] In specific implementation, the first connecting portion 111 is a bushing structure, and the second connecting arm 12 is rotatably connected to the first connecting arm 11 through the first connecting portion 111 of the bushing structure. The steering knuckle 30 is rotatably connected to the first connecting arm 11 through the second connecting portion 112 of the ball head structure. When the steering knuckle 30 is subjected to the impact force transmitted from the wheel, the steering knuckle 30 will swing and transmit the impact force to the first connecting arm 11 through the first connecting portion 111. At this time, the first connecting portion 111 drives the first connecting arm 11 to rotate, so as to adjust the direction of the impact force received by the first connecting arm 11 and avoid excessive impact on the connection between the first connecting arm 11 and the steering knuckle 30. Similarly, the second connecting portion 112 can alleviate the impact force between the first connecting arm 11 and the second connecting arm 12. Moreover, the setting of the first connecting portion 111 as a bushing structure can transmit the direction of the impact force to the first bushing 113 and the second bushing 121, so that the two can decouple the lateral support and longitudinal flexibility of the wheel, thereby improving the overall handling and comfort performance of the vehicle.

[0043] like Figures 1 to 3 As shown, the embodiment of the present application also provides a suspension structure, which includes the above-mentioned lower swing arm assembly 10, and the suspension structure also includes a subframe 20, a steering knuckle 30, a shock absorber assembly 40 and an upper swing arm 50. The steering knuckle 30 and the shock absorber assembly 40 are connected by the upper swing arm 50 and the lower swing arm assembly 10 arranged at intervals. The shock absorber assembly 40 includes a shock absorber 41 and a shock absorber bracket 42. The shock absorber bracket 42 is a fork arm structure, and the shock absorber bracket 42 of the fork arm structure is rotatably connected to both sides of the first connecting arm 11.

[0044] In a specific implementation, the upper swing arm 50 and the lower swing arm assembly 10 are connected between the sub-frame 20 and the steering knuckle 30 at intervals, which can effectively buffer the force exerted by the wheel on the steering knuckle 30 and transmit it to the sub-frame 20, wherein the shock absorber 41 of the shock absorber assembly 40 is installed on the first connecting arm 11 through the shock absorber bracket 42 of the fork arm structure, and the shock absorber bracket 42 can be rotatably connected to both sides of the first connecting arm 11 through the third connecting portion 114, so as to better transfer the vibration at the shock absorber 41 to the first connecting arm 11, and then from the first connecting arm 11 to the sub-frame 20, thereby achieving the effect of reducing vibration.

[0045] An embodiment of the present application also provides a vehicle, wherein the vehicle includes the above-mentioned suspension structure.

[0046] In a specific implementation, the vehicle of the embodiment of the present application includes a suspension structure, the suspension structure includes a lower swing arm assembly 10, the lower swing arm assembly 10 includes a first connecting arm 11 and a second connecting arm 12, the lower swing arm assembly 10 is connected between the steering knuckle 30 and the subframe 20 of the suspension structure through the first connecting arm 11, the first connecting arm 11 and the second connecting arm 12 are rotatably connected to different positions of the subframe 20 through the first bushing 113 and the second bushing 121 respectively, the other end of the second connecting arm 12 is movably connected to the first connecting arm 11 through the first connecting portion 111, during the driving process of the vehicle, the wheels will apply forces in different directions to the steering knuckle 30, and the steering knuckle 30 will transmit the force to the first connecting arm 11, because the second connecting arm 12 is movably connected to the first connecting arm 11 through the first connecting portion 111, so both ends of the second connecting arm 12 are movably connected, which is equivalent to a two-force rod, so that the second connecting arm 12 is only subjected to the force along its extension direction, and the second bushing 121 connected thereto is also only subjected to the radial force in the extension direction of the second connecting arm 12, and will not be subjected to the vertical axial force. Since the first connecting arm 11 has at least three connection points, the first bushing 113 connected thereto is subjected to both radial force and axial force. Therefore, the radial force and the axial force can be distributed through the first bushing 113 and the second bushing 121, thereby completing the decoupling of the wheel force, optimizing the lateral support and longitudinal flexibility of the wheel, and coordinating the vehicle's handling and comfort.
