[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] Suspension is an important vibration-damping connection component, which is widely used in the automotive industry. It can not only realize the reliable connection between two components, but also effectively attenuate the vibration transmission between components, which plays an important role in improving the comfort of the whole vehicle. Take the suspension component of the reducer as an example. When the vehicle passes through uneven roads, it is easy to bump. The impact force on the reducer comes from multiple directions. However, the suspension component in the related technology has a single damping direction and cannot adapt to complex vibration sources.

[0022] Reference below Figures 1 to 7 A suspension assembly 10 provided according to an embodiment of the present invention is described.

[0023] like Figures 1 to 4 As shown, the first embodiment of the present invention provides a suspension assembly 10 for reducing vibration of a reducer 20 of a vehicle, comprising a front suspension structure 100 and a rear suspension structure 200, wherein the front suspension structure 100 is arranged at the front side of the reducer 20; the front suspension structure 100 comprises a mounting shell 110 and a buffer 120, and the buffer 120 is mounted on the mounting shell 110; the buffer 120 at least limits the height direction of the vehicle (such as Figure 2 The buffer 120 is provided with a mounting hole 121; the rear suspension structure 200 is arranged at the rear side of the reducer 20; the rear suspension structure 200 includes a fixed shell 210 and a shock absorber 220, the shock absorber 220 is installed in the fixed shell 210, and the shock absorber 220 is used for shock absorption of the vehicle; the shock absorber 220 is provided with a fixing hole 221, and the axial direction of the fixing hole 221 intersects with the axial direction of the mounting hole 121.

[0024] The front suspension structure 100 limits the vibration of the vehicle in the height direction through the buffer 120, reduces the relative movement between the wheel and the reducer 20, and improves the comfort and stability of the vehicle. The front suspension structure 100 is arranged to share the load of the vehicle shock absorption, reduce the fatigue strength of the rear suspension structure 200, and improve the durability of the suspension assembly 10. The rear suspension structure 200 alleviates the vibration of the vehicle through the shock absorber 220, and has a shock absorption effect. The axial direction of the fixing hole 221 of the shock absorber 220 intersects with the axial direction of the mounting hole 121 of the buffer 122, so that the suspension assembly 10 can alleviate the impact force of the reducer 20 in multiple directions and improve the shock absorption effect.

[0025] The shock absorber 220 is connected to the vehicle frame through the fixing hole 221. During the driving of the vehicle, the shock absorber 220 moves along the axial direction of the fixing hole 221 to offset the impact force in the axial direction of the fixing hole 221. The buffer 122 is connected to the vehicle frame through the mounting hole 121. During the driving of the vehicle, the buffer 122 moves along the axial direction of the mounting hole 121 to offset the impact force in the axial direction of the mounting hole 121. The axial direction of the fixing hole 221 of the shock absorber 220 intersects with the axial direction of the mounting hole 121 of the buffer 122. When subjected to external impact force, the shock absorber 220 is compressed or extended along the axial direction of the fixing hole 221, and the buffer 122 is compressed or extended along the axial direction of the mounting hole 121, so that the vibration of the reducer 20 in all directions is reduced, and it can adapt to complex vibration sources and improve the shock absorption effect. The shock absorber 220 can be a shock absorbing material such as a spring or rubber. The structure of the shock absorber 220 may be set with reference to the buffer 120. Of course, in other embodiments, the shock absorber 220 may also have other structures, and the present invention does not specifically limit this.

[0026] The axial direction of the mounting hole 121 of the buffer member 122 can be the height direction of the vehicle, so as to improve the shock absorption effect of the front suspension structure 100 in the height direction of the vehicle, reduce the shock absorption pressure of the rear suspension structure 200 in the height direction of the vehicle, and thus reduce the fatigue strength of the rear suspension structure 200.

[0027] The front side of the reducer 20 is the side of the reducer 20 close to the front of the vehicle, and the rear side of the reducer 20 is the side of the reducer 20 away from the rear of the vehicle. At least two front suspension structures 100 can be provided, and at least two rear suspension structures 200 can be provided. Through multiple front suspension structures 100 and rear suspension structures 200, the overall shock absorption effect of the suspension assembly 10 can be improved, and the redundancy of the suspension assembly 10 can be improved.

[0028] like Figure 2 As shown, in some embodiments, the buffer 120 includes a buffer member 122, a first limit member 123 and a second limit member 124, and the first limit member 123 and the second limit member 124 are respectively arranged on both sides of the buffer member 122 along the height direction of the vehicle.

[0029] The buffer 122 can reduce the vibration of the vehicle during driving by deformation. When the wheel encounters an uneven road surface, the buffer 122 can absorb and reduce the transmission of road impact, preventing the reducer 20 from violent jumping and shaking; the first limiter 123 and the second limiter 124 support the buffer 122, so that the buffer 122 can evenly distribute the load when deformed, preventing local excessive compression from causing failure. The first limiter 123 and the second limiter 124 are arranged on both sides of the buffer 122. The displacement range of the buffer 122 is limited by the first limiter 123 and the second limiter 124, avoiding excessive compression, stretching or deformation of the buffer 122 during operation, thereby maintaining the stability of the suspension assembly 10. The coordination of the first limiter 123, the second limiter 124 and the buffer 122 helps the suspension assembly 10 to better absorb and dissipate vibration and improve the overall shock absorption performance.

[0030] The first limit member 123 and the second limit member 124 are respectively arranged on both sides of the buffer member 122 along the height direction of the vehicle. When the buffer member 122 is subjected to the impact force in the height direction of the vehicle, the first limit member 123 and the second limit member 124 can limit the movement range of the buffer member 122 to avoid excessive deformation of the buffer member 122. While the front suspension structure 100 has a shock-absorbing effect in the height direction of the vehicle, it ensures the stability of the suspension assembly 10.

[0031] Among them, the first limiter 123 and the second limiter 124 can be a plate body. Under the premise of ensuring the supporting effect of the plate body on the buffer 122, the volume of the first limiter 123 and the second limiter 124 can be minimized, thereby reducing the overall volume of the suspension assembly 10. The buffer 122 is generally made of rubber. Rubber has good elasticity and can deform when subjected to external forces to absorb external vibration and impact energy. When the external force stops, the rubber will quickly return to its original state. Rubber can effectively absorb and alleviate the energy caused by vibration or impact, reducing the impact of these forces on the reducer 20. The internal friction and viscoelastic properties of rubber enable it to dissipate vibration energy during deformation, effectively reduce unnecessary mechanical shocks, and extend the service life of the reducer 20.

[0032] like Figure 5As shown, in some embodiments, the buffer 120 further includes a first support member 125 and a second support member 126, and the second support member 126 is sleeved outside the first support member 125; the buffer 122 is connected to the first support member 125 and the second support member 126, and is located between the first support member 125 and the second support member 126; the first support member 125 and the second support member 126 support and protect the buffer 122, prevent external forces from directly acting on the buffer 122, and minimize the probability of the buffer 122 being damaged. In addition, the first support member 125 and the second support member 126 can limit the range of motion of the buffer 122 to prevent the buffer 122 from being overstretched or compressed. Specifically, the first support member 125 and the second support member 126 are roughly cylindrical, so that the second support member 126 can be mounted outside the first support member 125; when the surface area is the same, the volume of the cylindrical structure is larger; setting the first support member 125 and the second support member 126 as a cylindrical structure can reduce the material used for the first support member 125 and the second support member 126.

[0033] In some embodiments, the first support member 125 is used to connect the vehicle frame, and the second support member 126 is used to connect the reducer 20 of the vehicle; when the wheel encounters an uneven road surface, the vibration is transmitted from the vehicle frame to the buffer member 122 through the first support member 125, and the buffer member 122 absorbs and reduces the impact caused by the uneven road surface, thereby preventing the reducer 20 from violently jumping and shaking. Generally, the first support member 125 and the second support member 126 are both made of hard materials, such as stainless steel; the mounting hole 121 can be penetrated by the first limit member 123, the first support member 125 and the second limit member 124, and a connecting shaft can be set on the vehicle frame, and the connecting shaft is penetrated in the mounting hole 121. The axial direction of the mounting hole 121 can be the height direction of the vehicle, which is beneficial to the shock absorption of the front suspension structure 100 in the height direction of the vehicle.

[0034] like Figure 6 As shown, in some embodiments, a first extension portion 125a is provided on a side of the first support member 125 facing the second support member 126, and a second extension portion 126a is provided on a side of the second support member 126 facing the first support member 125, and the projections of the first extension portion 125a and the second extension portion 126a in the height direction of the vehicle at least partially overlap; the buffer member 122 is connected to the first extension portion 125a and the second extension portion 126a, and is located between the first extension portion 125a and the second extension portion 126a.

[0035] The projections of the first extension part 125a and the second extension part 126a in the height direction of the vehicle at least partially overlap, so that when the buffer 122 is stretched or compressed in the height direction of the vehicle, the first extension part 125a and the second extension part 126a can limit the buffer 122 to prevent the buffer 122 from being excessively deformed; the projections of the first extension part 125a and the second extension part 126a in the height direction of the vehicle can be partially overlapped or completely overlapped, as long as the first extension part 125a and the second extension part 126a can prevent the buffer 122 from being excessively deformed in the height direction of the vehicle. The first extension part 125a and the second extension part 126a are both connected to the buffer 122 to prevent the buffer 122 from being separated from the first extension part 125a or the second extension part 126a during the deformation process, thereby improving the limiting effect of the first extension part 125a and the second extension part 126a on the buffer 122.

[0036] A first extension portion 125a is provided on one side of the first support member 125 facing the second support member 126, and a second extension portion 126a is provided on one side of the second support member 126 facing the first support member 125, so as to restrict the buffer member 122 from multiple directions of the buffer member 122, thereby preventing excessive deformation of the buffer member 122, and improving the stability of the front suspension structure 100. The first support member 125 and the first extension portion 125a can be integrally formed to improve processing efficiency; similarly, the second support member 126 and the second extension portion 126a can be integrally formed. The outer surface of the first extension portion 125a and the outer surface of the first support member 125 are both cambered surfaces, so that the surface lines of the first extension portion 125a and the second support member 126 are smoother, reducing the probability that the first extension portion 125a or the first support member causes damage to the buffer member 122, the second extension portion 126a or the second support member 126 during collision; similarly, the outer surface of the second extension portion 126a and the outer surface of the second support member 126 are both cambered surfaces.

[0037] like Figure 6 to Figure 7As shown, in some embodiments, a buffer gap 128 is formed between the first extension portion 125a and the first limit member 123 or the second limit member 124, so that the movement of the first extension portion 125a or the second extension portion 126a is more flexible, reducing the restriction of the first limit member 123 or the second limit member 124 on the first extension portion 125a; when the buffer member 122 is impacted in the height direction of the vehicle, the buffer member 122 is squeezed toward the first extension portion 125a, and the buffer gap 128 allows the first extension portion 125a to have sufficient movement space, so that the first extension portion 125a can move toward the first limit member 123 or the second limit member 124; using the buffer gap 128, the first extension portion 125a can be deformed to offset part of the impact force when the impact is large; the first extension portion 125a can ensure the shock absorption effect of the front suspension structure 100 while limiting the excessive deformation of the buffer member 122.

[0038] In some embodiments, the buffer member 122 has a buffer groove 122a, the depth direction of the buffer groove 122a is the height direction of the vehicle; when the vehicle is subjected to a horizontal impact force, the side walls of the buffer groove 122a are squeezed to offset the impact force; the buffer groove 122a can be annular, and the buffer groove 122a surrounds the circumference of the first support member 125 to offset the impact force of the buffer member 122 in the circumferential direction. Generally, the width of the buffer groove 122a is smaller than the depth of the buffer groove 122a, so that the side walls of the buffer groove 122a can quickly abut when subjected to an impact force, thereby alleviating and reducing vibration.

[0039] like Figure 6 As shown, in some embodiments, at least two buffer grooves 122a are provided, and at least two buffer grooves 122a are staggered in the height direction of the vehicle. The buffer grooves 122a located at different positions can improve the shock absorbing effect of the buffer member 122 at different positions.

[0040] like Figure 6 As shown, in some embodiments, the buffer 122 is provided with at least two or more buffers 122, which can effectively disperse the vibration and reduce the burden on each buffer 122, thereby avoiding premature wear or failure of the buffer 122 due to excessive local pressure. At least two buffers 122 are arranged along the height direction of the vehicle, which can provide additional shock absorption protection at different height positions, so that the vibration and impact energy can be absorbed at multiple positions to balance the overall shock absorption effect and adapt to complex vibration sources; in addition, multiple buffers 122 are provided to increase the redundancy and stability of the suspension assembly 10. The buffer 122 can be provided with two, three, four, five or six. The embodiment of the present invention does not specifically limit the number of buffers 122. This article takes a single front suspension structure 100 with two buffers 122 as an example, and the two buffers 122 are respectively a first buffer 122d and a second buffer 122e.

[0041] like Figure 1 , Figure 3 and Figure 7 As shown, the front side of the reducer 20 is fixedly connected to the mounting shell 110, and the mounting shell 110 has a mounting groove 111, and the mounting groove 111 is a through groove, that is, the mounting groove 111 has a first notch 111a and a second notch 111b, and the first stopper 123 is arranged at the first notch 111a, and the second stopper 124 is arranged at the second notch 111b, and each buffer 122 is pressed into the mounting groove 111 by press-fitting; wherein, the third extension part 126b is arranged on the side of the second support member 126 away from the first support member 125, and the third extension part 126b extends in a direction away from the first support member 125. When the buffer 122 is pressed into the mounting groove 111, the third extension part 126b can abut against the end surface of the first notch 111a or the second notch 111b to limit the buffer 122 from continuing to be pressed into the mounting groove 111, which is beneficial to the assembly of the front suspension structure 100. Similarly, the rear side of the reducer 20 is fixedly connected to the fixing shell 210 to be fixedly connected to the rear suspension structure 200 .

[0042] like Figure 6 to Figure 7 As shown, in some embodiments, a buffer space 127 is formed between at least one of the first stopper 123 and the second stopper 124 and the second support member 126, and at least one of the first stopper 123 and the second stopper 124 is provided with a buffer portion 124a on the side facing the buffer space 127; the buffer space 127 reserves sufficient activity space for the second support member 126, so that the second support member 126 can move relative to the first stopper 123 or the second stopper 124 to achieve the purpose of dispersing the impact energy, thereby achieving shock absorption. In the case where the impact force on the suspension assembly 10 is too large, the first stopper 123 or the second stopper 124 abuts against the second support member 126 to prevent the buffer member 122 from being excessively deformed under the action of the excessive impact force. At this time, the buffer portion 124a plays the role of alleviating the impact force to weaken the force between the first stopper 123 or the second stopper 124 and the second support member 126. The buffer portion 124a is generally made of rubber.

[0043] For example, a buffer space 127 is formed between the first stopper 123 and the third extension 126b, and the buffer 122 has a buffer layer 122f, which is at least partially attached to the side of the third extension 126b facing the buffer space 127 to reduce the force between the first stopper 123 and the third stopper, and reduce the possibility of deformation of the first stopper 123 or the third stopper. The buffer layer 122f can be partially attached to the side of the second support member 126 facing the first support member 125 to relieve the impact force between the first support member 125 and the second support member 126.

[0044] In this embodiment, a buffer space 127 is formed between the first stopper 123 and the second support member 126, and a buffer space 127 is formed between the second stopper 124 and the second support member 126, and the first stopper 123 and the second stopper 124 are both provided with a buffer portion 124a; in other embodiments, a buffer space 127 may be formed between the first stopper 123 and the second support member 126, and the first stopper 123 is provided with a buffer portion 124a; or a buffer space 127 may be formed between the second stopper 124 and the second support member 126, and the second stopper 124 is both provided with a buffer portion 124a. A plurality of buffer portions 124a may be provided, and the plurality of buffer portions 124a are arranged along the circumferential direction of the first stopper 123.

[0045] like Figure 6 As shown, in some embodiments, the buffer groove 122a includes a first buffer groove 122b, and the notches of the first buffer grooves 122b of two adjacent buffer members 122 are arranged oppositely, so that the first buffer grooves 122b of the two buffer members 122 are connected, thereby improving the unity and coordination between the two adjacent buffer members 122, so that the two adjacent buffer members 122 work together to offset the external impact force. The notch of the first buffer groove 122b is located on the side of the second extension part 126a close to the first support member 125, that is, the first buffer groove 122b is close to the inner side of the buffer 120, and the second extension part 126a is close to the outer side of the buffer 120, so that the second extension part 126a can better play a protective role on the buffer member 122. The first buffer 122d and the second buffer 122e are arranged adjacent to each other, and the second extension portion 126a connecting the first buffer 122d abuts against the second extension portion 126a connecting the second buffer 122e; the second extension portion 126a can isolate the first buffer 122d and the second buffer 122e, reduce the transmission of vibration energy in the height direction of the vehicle, and thus improve the shock absorption effect.

[0046] In some embodiments, the buffer groove 122a includes a second buffer groove 122c, and the second buffer groove 122c has a shock-absorbing effect in the horizontal direction of the vehicle; the second buffer groove 122c is connected to the buffer space 127, so that the first limit member 123, the second limit member 124 and the first extension portion 125a have sufficient displacement space, thereby improving the flexibility of the first limit member 123 and the second limit member 124, and then when subjected to a huge impact force, the first limit member 123, the second limit member 124 and the first extension portion 125a have a larger moving space and more movement directions relative to the second support member 126, thereby improving the shock-absorbing performance; the notch of the first buffer groove 122b and the notch of the second buffer groove 122c of the same buffer member 122 face different directions, thereby minimizing the phenomenon of local stress concentration as much as possible to increase the life of the buffer member 122. Compared with the first buffer groove 122b, the second buffer groove 122c is closer to the center of the buffer 120, and the width of the second buffer groove 122c is greater than the width of the first buffer groove 122b; compared with the first buffer groove 122b, the second buffer groove 122c is closer to the first support member 125, and the vibration energy it receives is larger. The width of the second buffer groove 122c is limited to a smaller value, so that the buffer member 122 can limit the transmission of vibration energy in time, thereby improving the shock absorption effect. The bottom of the first buffer groove 122b and the second buffer groove 122c is a concave arc, which can reduce the probability of dust and other impurities remaining inside the first buffer groove 122b and the second buffer groove 122c, and facilitate cleaning.
