Detailed Description of the Invention

[0031] The embodiments of the present invention will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Below, reference is made to Figures 1 - 3 Describe the connecting assembly 100 for the suspension system 200 according to the first aspect embodiment of the present invention.

[0032] For example, in Figure 1 and Figure 2In the example, the connection assembly 100 for the suspension system 200 according to the first aspect of the present invention includes a first connection member 1 and a second connection member 2.

[0033] Specifically, the first connecting member 1 is adapted to be connected to the shock absorber 201 of the suspension system 200 . The second connecting member 2 is adapted to be connected to the body 301 of the vehicle 300 . The first connecting member 1 is movable relative to the second connecting member 2 .

[0034] For example, in Figure 1 、 Figure 2 and Figure 4 In the example shown, first connecting member 1 is located below second connecting member 2. First connecting member 1 cooperates with and is connected to shock absorber 201 of suspension system 200. Second connecting member 2 is fixedly connected to body 301 of vehicle 300. When vehicle 300 moves and shock absorber 201 deflects relative to its axis, first connecting member 1 moves with shock absorber 201 relative to second connecting member 2 to achieve the deflection.

[0035] Taking air suspension as an example, in traditional technology, the shock absorber is rigidly connected to the vehicle body. When a vehicle's air suspension encounters adverse conditions (such as bumpy roads or violent vehicle movement), the shock absorber deflects relative to the vehicle, causing the air spring (e.g., the bladder) outside the shock absorber to deflect accordingly. This results in additional motion interference between the shock absorber and the air spring, generating lateral forces. Simultaneously, the air spring deforms due to tilt, resulting in unequal volumes between the opposing halves of the air spring, which in turn generates lateral forces on the shock absorber. This also applies lateral forces to the shock absorber's piston rod, which in turn affects the performance of the air suspension.

[0036] In this application, the relative motion of the first connector 1 and the second connector 2 increases the freedom of movement of the connection assembly 100. When the vehicle 300 encounters adverse operating conditions, the shock absorber 201 can move relative to the vehicle body 300, effectively reducing or eliminating the lateral force generated during the deflection of the shock absorber 201. This reduces abnormal noise in local areas of the vehicle 300 (e.g., the elastic component 202), improves passenger comfort, and enhances the operational stability of the shock absorber 201, thereby enhancing the handling stability and safety of the suspension system 200. Furthermore, this effectively reduces the torque generated by the connection assembly 100 during intense movement, reduces abnormal noise, and improves the acoustic vibration harshness (NVH) of the suspension system 200. Furthermore, during use, the shock absorber 201 avoids local stress concentration in the suspension system 200, thereby reducing material fatigue and improving sealing, thereby extending the service life of the suspension system 200 and enhancing its adjustability. In addition, the connecting assembly 100 can be used in different suspension systems 200, has high versatility, does not need to be newly designed, and is easy to use. Moreover, the connecting assembly 100 is installed between the vehicle body 301 and the suspension system 200 to play the role of connection and support.

[0037] The connecting assembly 100 for the suspension system 200 according to the present invention increases the freedom of movement of the connecting assembly 100, effectively reducing the torque generated by the connecting assembly 100 during intense movement and effectively reducing or eliminating the lateral force generated by the shock absorber 201 during deflection. This reduces abnormal noise, improves the acoustic harshness of the suspension system 200, enhances passenger comfort, and improves the handling stability and safety of the suspension system 200. Furthermore, it reduces material fatigue and improves sealing performance, thereby extending the service life of the suspension system 200 and enhancing its adjustability. Furthermore, it is highly versatile, requiring no new design and is easy to use.

[0038] According to some embodiments of the present invention, referring to Figure 2 , the first connecting member 1 is movable relative to the second connecting member 2 along the assembly direction of the first connecting member 1 and the second connecting member 2, and the first connecting member 1 is swingable relative to the second connecting member 2 along the central axis of the connecting assembly 100. For example, Figure 2 In the example, the above-mentioned assembly direction is the direction in which the second connecting member 2 and the first connecting member 1 are installed (eg Figure 2In the direction indicated by arrow H, when the central axis of the first connecting member 1 deflects relative to the central axis of the second connecting member 2, for the two radially opposite portions of the first connecting member 1, one part of the first connecting member 1 moves upward and the other part of the first connecting member 1 moves downward along the assembly direction. With such a setting, it is further ensured that the first connecting member 1 is movable relative to the second connecting member 2, so that when the piston rod 2012 of the shock absorber 201 deflects, the first connecting member 1 deflects together with the piston rod 2012, so as to enable the shock absorber 201 to move relative to the vehicle body 301, thereby further weakening or eliminating the lateral force and improving the stability and safety of the suspension system 200 during use.

[0039] Further, with reference to Figure 2 , the first connecting member 1 is rotatable about the central axis of the connecting assembly 100; and / or, the second connecting member 2 is rotatable about the central axis of the connecting assembly 100. For example, the arrangements of the first connecting member 1 and the second connecting member 2 include the following situations: First, only the first connecting member 1 is rotatable about the central axis of the connecting assembly 100. Second, only the second connecting member 2 is rotatable about the central axis of the connecting assembly 100. Third, the first connecting member 1 and the second connecting member 2 are respectively rotatable about the central axis of the connecting assembly 100. With such a setting, on the basis of ensuring that the first connecting member 1 can deflect relative to the second connecting member 2 along the connecting assembly 100, the first connecting member 1 can rotate relative to the second connecting member 2 along the central axis of the connecting assembly 100, further improving the flexibility of the movement of the first connecting member 1 relative to the second connecting member 2, and thus improving the flexibility of the use of the connecting assembly 100.

[0040] According to some embodiments of the present invention, with reference to Figure 2 , the second connecting member 2 is in surface contact with the first connecting member 1. For example, in the example of Figure 2 , the connection between the second connecting member 2 and the first connecting member 1 is in surface contact. With such a setting, the smoothness of the movement at the mating part of the first connecting member 1 and the second connecting member 2 is increased, facilitating the rotation of the first connecting member 1 relative to the second connecting member 2, thereby improving the smoothness when the first connecting member 1 deflects with the shock absorber 201 and improving the service performance of the connecting assembly 100.

[0041] According to some embodiments of the present invention, with reference to Figure 2 , a mating groove 11 is formed on one of the first connecting member 1 and the second connecting member 2, and a mating portion 211 is provided on the other of the first connecting member 1 and the second connecting member 2, and at least a part of the mating portion 211 is movably fitted in the mating groove 11. For example, the arrangements of the mating portion 211 and the mating groove 11 include the following situations: First, the mating groove 11 is formed on the first connecting member 1 and the mating portion 211 is provided on the second connecting member 2 (such as Figure 2As shown). Second, the fitting groove 11 is formed on the second connecting member 2, and the fitting portion 211 is provided on the first connecting member 1. The free end of the fitting portion 211 is fitted in the fitting groove 11. During the yawing process, the fitting portion 211 slides along the side wall of the fitting groove 11. With such a setting, the relative movement between the first connecting member 1 and the second connecting member 2 is achieved through the cooperation of the fitting portion 211 and the fitting groove 11. The structure of the fitting portion 211 and the fitting groove 11 is simple, easy to install, and does not occupy space, thereby improving the assembly efficiency of the first connecting member 1 and the second connecting member 2, and also facilitating the arrangement of the connecting assembly 100 in the suspension system 200, and further improving the installation efficiency of the suspension system 200.

[0042] According to some embodiments of the present invention, referring to Figure 2 , on one side in the thickness direction of the first connecting member 1 (such as the up and down direction as shown Figure 2 ), a fitting groove 11 is formed, and on one side of the second connecting member 2 facing the fitting groove 11, a fitting portion 211 is provided, and the fitting portion 211 extends along the circumferential direction of the second connecting member 2. For example, in the example of Figure 2 , the first connecting member 1 is located below the second connecting member 2, the fitting groove 11 is formed on the upper side of the first connecting member 1, the fitting portion 211 is formed on the lower side of the second connecting member 2, the lower end of the fitting portion 211 is fitted in the fitting groove 11, and the fitting portion 211 is substantially annular. With such a setting, the contact area between the first connecting member 1 and the second connecting member 2 is increased, thereby improving the assembly stability of the first connecting member 1 and the second connecting member 2, and improving the use stability of the connecting assembly 100. In addition, the first connecting member 1 can be rotated circumferentially relative to the second connecting member 2, and the first connecting member 1 can also move flexibly at multiple angles relative to the second connecting member 2. For example, the first connecting member 1 can yaw relative to the second connecting member 2 in different directions along the circumferential direction of the connecting assembly 100, so that the first connecting member 1 can move relative to the second connecting member 2 after being acted on by the shock absorber 201 to cope with different road conditions, improving the flexibility of the rotation of the first connecting member 1 relative to the second connecting member 2, and improving the flexibility of the use of the connecting assembly 100. In addition, the middle region of the second connecting member 2 can form an avoidance for the piston rod 2012 of the shock absorber 201, facilitating the connection between the connecting assembly 100 and the piston rod 2012.

[0043] According to some embodiments of the present invention, referring to Figure 2 , at least a part of the outer peripheral surface of the fitting portion 211 is configured as a part of the spherical surface of a sphere, and the shape of the fitting groove 11 is adapted to the shape of at least a part of the outer peripheral surface of the fitting portion 211. For example, in Figure 2In the example, the lower end of the mating portion 211 is a part of the spherical surface of a sphere. Along the direction from top to bottom, the distance between the opposite side surfaces of the mating portion 211 gradually increases, that is, along the direction from top to bottom, the diameter of the mating portion 211 gradually increases. The shape of the mating groove 11 is adapted to the shape of the outer peripheral surface of the lower end of the mating portion 211. With such a setting, it is convenient for the mating portion 211 to slide in the mating groove 11, further improving the smoothness of the rotation of the first connecting member 1 relative to the second connecting member 2, and further improving the use efficiency of the connecting assembly 100. In addition, the upper end of the mating groove 11 is limited to the lower end of the mating portion 211, improving the stability of the cooperation between the mating portion 211 and the mating groove 11, effectively preventing the mating portion 211 from falling out of the mating groove 11, thereby improving the assembly stability of the first connecting member 1 and the second connecting member 2, and improving the use stability of the connecting assembly 100. In addition, the structure of the mating portion 211 is simple, the installation is simple, and it does not occupy space. Among them, the thickness of the mating portion 211 is 10 mm, but it is not limited thereto. The thickness of the mating portion 211 can be specifically set according to the setting of the mating groove 11 and the actual use situation to meet the actual needs.

[0044] According to some embodiments of the present invention, referring to Figure 5 , the radius of the sphere is r, where r satisfies: 45 mm ≤ r ≤ 70 mm. For example, in Figure 5 's example, the minimum radius of movement of the mating portion 211 is r. When the radius r of the sphere is less than 45 mm, the minimum radius of movement of the mating portion 211 is smaller, reducing the distance between the mating portion 211 and the piston rod 2012 of the shock absorber 201. When the connecting assembly 100 is mated with the piston rod 2012 of the shock absorber 201, mutual interference is likely to occur, increasing the assembly difficulty of the connecting assembly 100 and the shock absorber 201. When the radius r of the sphere is greater than 70 mm, the minimum radius of movement of the mating portion 211 is larger, increasing the occupied space of the connecting assembly 100 on the vehicle 300 and increasing the arrangement difficulty of the suspension system 200 on the vehicle 300. Thus, by setting the radius r of the sphere to satisfy: 45 mm ≤ r ≤ 70 mm, the radius of the sphere is reasonably set, that is, the size of the mating portion 211 is reasonably set, so as to facilitate the assembly of the connecting structure and the piston rod 2012 of the shock absorber 201, improving the assembly efficiency. In addition, the occupied space of the connecting assembly 100 on the vehicle 300 is also reduced, and the arrangement difficulty of the suspension system 200 on the vehicle 300 is reduced, thereby improving the installation efficiency of the suspension system 200. Among them, the radius r of the sphere is preferably 45 mm.

[0045] According to some embodiments of the present invention, referring to Figure 2, the second connecting member 2 includes a ball head skeleton 21 and a support skeleton 22, and the ball head skeleton 21 has a mating portion 211. The support skeleton 22 is connected to the side of the ball head skeleton 21 away from the first connecting member 1, and a part of the support skeleton 22 is located on the outer peripheral side of the ball head skeleton 21. There is a gap between the inner wall surface of a part of the support skeleton 22 and the outer peripheral surface of the side of the first connecting member 1 facing the second connecting member 2.

[0046] For example, in Figure 2 's example, the upper side surface of the ball head skeleton 21 is connected to the lower side surface of the support skeleton 22, and the upper end of the mating portion 211 is connected to the side surface of the ball head fastener away from the support skeleton 22. There is a gap between the inner wall surface of a part of the support skeleton 22 and the outer peripheral surface of the upper end of the first connecting member 1. With such a setting, when ensuring that the first connecting member 1 can move relative to the second connecting member 2, interference between the first connecting member 1 and the support skeleton 22 during yawing is avoided, so that the first connecting member 1 can move relative to the second connecting member 2 normally, and thus the connecting assembly 100 can be used normally for a long time.

[0047] According to some embodiments of the present invention, referring to Figure 2 , the support skeleton 22 includes a first skeleton segment 221, a second skeleton segment 222, and a third skeleton segment 223.

[0048] Specifically, one end of the first skeleton segment 221 is connected to the ball head skeleton 21, and the other end of the first skeleton segment 221 extends in a direction away from the center of the second connecting member 2. The second skeleton segment 222 is provided on the outer peripheral side of the ball head skeleton 21. The second skeleton segment 222 is located on the side of the first skeleton segment 221 facing the first connecting member 1, and the second skeleton segment 222 is adapted to be connected to the vehicle body 301. The third skeleton segment 223 is connected between the first skeleton segment 221 and the second skeleton segment 222, and there is a gap between the third skeleton segment 223 and the first connecting member 1.

[0049] For example, in Figure 2 's example, one end of the first skeleton segment 221 facing the central axis of the second connecting member 2 is connected to the ball head skeleton 21. The second skeleton segment 222 is located below the first skeleton segment 221. The upper end of the third skeleton segment 223 is connected to the above-mentioned other end of the first skeleton segment 221, and the lower end of the third skeleton segment 223 is connected to one end of the second skeleton segment 222 (the end of the second skeleton segment 222 close to the central axis of the second connecting member 2). The other end of the second skeleton segment 222 extends in a direction away from the central axis of the second connecting member 2. There is a gap between the inner side surface of the third skeleton segment 223 and the outer peripheral surface of the first connecting member 1. The support skeleton 22 is in the shape of a round cap. The installation position of the vehicle body 301 can also be located above the support skeleton 22, and the outer shape of the support skeleton 22 can be flexibly designed according to needs.

[0050] With such a setting, it effectively ensures that there is a gap between the support skeleton 22 and the first connecting member 1, which is beneficial to the long-term normal use of the connecting assembly 100. In addition, the support skeleton 22 has a simple structure and is easy to form, thus improving the production efficiency of the support skeleton 22. It should be noted that the first skeleton section 221 and the ball head skeleton 21 are connected by fasteners 3 (such as bolts and screws). A plurality of mounting holes 2231 are formed on the third skeleton section 223, and the plurality of mounting holes 2231 extend along the circumferential direction of the third skeleton section 223. For example, three mounting holes 2231 are arranged at equal intervals along the circumferential direction of the third skeleton section 223, and the plurality of fasteners 3 respectively pass through the corresponding mounting holes 2231 and are connected to the vehicle body 301. The material of the support skeleton 22 can be AlSi 10 MnMg, and it is formed by machining with a casting machine, so that the support skeleton 22 has excellent mechanical properties and improves the structural strength. It should be noted that the mounting position of the vehicle body 301 can be located on the upper side or the lower side of the third skeleton section 223, and is specifically set according to the actual use situation. In the description of the present invention, the meaning of "a plurality" is two or more.

[0051] According to some embodiments of the present invention, referring to Figure 2 , it extends obliquely from the second connecting member 2 towards the first connecting member 1 and the third skeleton section 223 extends obliquely towards the side away from the ball head skeleton 21.

[0052] For example, in the Figure 2 example, along the direction from top to bottom, the third skeleton section 223 extends obliquely towards the outer peripheral side away from the ball head skeleton 21. With such a setting, the third skeleton section 223 extends obliquely, improving the structural strength of the support skeleton 22, thereby extending the service life of the support skeleton 22. In addition, the connection stability between the connecting assembly 100 and the vehicle body 301 is also strengthened through the support skeleton 22, facilitating the long-term normal use of the connecting assembly 100.

[0053] According to some embodiments of the present invention, referring to Figure 2 , the first connecting member 1 includes a connecting member body 12 and a first cover plate 13. The connecting member body 12 has a convex structure 1221, and the convex structure 1221 protrudes towards the side where the second connecting member 2 is located. The first cover plate 13 is connected to the connecting member body 12, the first cover plate 13 is arranged on the outer peripheral side of the convex structure 1221, and the first cover plate 13, the convex structure 1221 and the connecting member body 12 jointly define a mating groove 11.

[0054] For example, in Figure 2In the example, the connecting member body 12 is disposed on the outer peripheral side of the piston rod 2012 of the shock absorber 201, and the convex structure 1221 is connected to the upper end of the connecting member body 12. The lower end of the first cover plate 13 is connected to the upper side surface of the connecting member body 12. The inner wall surface of the first cover plate 13 is arc-shaped, the outer peripheral surface of the first cover plate 13 is stepped, and the outer peripheral surface of the convex structure 1221 is arc-shaped. The inner wall surface of the first cover plate 13, the outer peripheral surface of the convex structure 1221, and the upper side surface of the connecting member body 12 jointly define the fitting groove 11. With such a setting, the fitting groove 11 is formed by splicing the first cover plate 13, the convex structure 1221, and the connecting member body 12. The structure is simple, facilitating the formation of the fitting groove 11, thereby improving the production efficiency of the first connecting member 1. In addition, the structural strength of the first cover plate 13 is also improved, reducing the probability of the first cover plate 13 breaking after long-term use, thereby extending the service life of the first connecting member 1.

[0055] According to some embodiments of the present invention, referring to Figure 2 , a first through hole 1211 is formed in the connecting member body 12, and the piston rod 2012 of the shock absorber 201 is adapted to be fitted in the first through hole 1211 to be connected to the first connecting member 1.

[0056] The connecting member body 12 includes an inner housing 121, an outer housing 122, and a first buffer member 124. A first through hole 1211 is formed in the inner housing 121, and the piston rod 2012 of the shock absorber 201 is adapted to be fitted in the first through hole 1211 to be connected to the first connecting member 1. The outer housing 122 is disposed on the outer peripheral side of the inner housing 121, the convex structure 1221 is disposed on the outer housing 122, the outer housing 122 and the inner housing 121 jointly define an accommodation space 123, and the first buffer member 124 is disposed in the accommodation space 123.

[0057] For example, in Figure 2 's example, the first through hole 1211 is formed in the inner housing 121, the piston rod 2012 of the shock absorber 201 passes through the first through hole 1211 and is in tight fit with the inner housing 121. The outer housing 122 is sleeved on the outer peripheral side of the inner housing 121. The lower end of the convex structure 1221 is connected to the upper side surface of the outer housing 122, and the first buffer member 124 is located between the inner housing 121 and the outer housing 122. With such a setting, it is not only convenient for the piston rod 2012 of the shock absorber 201 to cooperate with the connection structure, but also the sealing performance of the cooperation between the first connecting member 1 and the piston rod 2012 of the shock absorber 201 is strengthened by the inner housing 121, avoiding the liquid in the shock absorber 201 from flowing out, and improving the service performance of the shock absorber 201. In addition, the cooperation between the fitting groove 11 and the fitting portion 211 reduces the swing angle of the first buffer member 124, reduces the force, reduces the wear degree and the fatigue of the material, and also reduces abnormal noise.

[0058] Wherein, a sealing ring 14 is provided between the inner housing 121 and the outer peripheral wall of the piston rod 2012, a bushing 15 is provided between the first buffer member 124 and the outer housing 122, at least one concave ring 16 is formed on the inner side wall of the outer housing 122, at least one sealing ring 14 is provided between the bushing 15 and the inner side wall of the outer housing 122, the sealing ring 14 is installed in the concave ring 16, when there are multiple sealing rings 14, the multiple sealing rings 14 are arranged at intervals in the up and down direction to seal between the outer housing 122 and the bushing 15, thereby further improving the sealing performance between the first connecting member 1 and the piston rod 2012, which is beneficial to the long-term normal use of the suspension system 200. A groove 17 is formed on the side of the first buffer member 124 facing the inner housing 121, and one end of the inner housing 121 facing the first buffer member 124 is press-fitted into the groove 17, with an interference fit, strengthening the sealing performance of the connection between the first buffer member 124 and the inner housing 121. The first buffer member 124 is the main component of the connection assembly 100, the first buffer member 124 is integrally formed of a rubber (NR) member, the upper part of the first buffer member 124 is spaced by a plurality of damping blocks along the circumferential direction of the first buffer member 124, and the lower part of the first buffer member 124 extends continuously along the circumferential direction of the first buffer member 124, thereby improving the stiffness of the first buffer member 124 and having a good damping and noise isolation effect.

[0059] According to some embodiments of the present invention, with reference to Figure 2 , the connecting member body 12 further includes a second cover plate 125 and at least one second buffer member 126. The second cover plate 125 is provided on the side of the outer housing 122 away from the second connecting member 2. A second through hole 1251 is formed on the second cover plate 125, and the second through hole 1251 and the first through hole 1211 are opposite to each other along the axial direction of the first connecting member 1. The second buffer member 126 is provided on the side of the second cover plate 125 away from the second connecting member 2.

[0060] For example, in Figure 2In the example, the second cover plate 125 is disposed on the lower side surface of the outer housing 122. The second through hole 1251 penetrates through the second cover plate 125. The first through hole 1211 and the second through hole 1251 communicate with each other in the up and down direction. The piston rod 2012 of the shock absorber 201 sequentially passes through the second through hole 1251 and the first through hole 1211. The second buffer member 126 is connected to the lower side surface of the second cover plate 125. With such an arrangement, when the piston rod 2012 of the shock absorber 201 moves downward, the second buffer member 126 moves downward along with the piston rod 2012 under the cooperation of the first connecting member 1 and the piston rod 2012. The second buffer member 126 contacts the cylinder block 2011 of the shock absorber 201. The second buffer member 126 absorbs the impact force from the shock absorber 201 and the spring (such as the air spring member 2021 or the coil spring 2022) of the suspension system 200 through deformation, and slows down the force finally transmitted by the shock absorber 201 to the vehicle body 301, thereby improving the stability of the vehicle body 301 and the driving stability of the vehicle 300. However, it is not limited thereto. For example, a plurality of second buffer members 126 are provided, and the plurality of second buffer members 126 are arranged at intervals along the circumferential direction of the second cover plate 125 to further improve the buffering effect. The second cover plate 125 and the outer housing 122 are connected by riveting and are in interference fit.

[0061] According to some embodiments of the present invention, the second buffer member 126 and the second cover plate 125 are integrally formed. For example, the second buffer member 126 and the second cover plate 125 are integrally formed by vulcanization. Thereby, the connection stability between the second buffer member 126 and the second cover plate 125 is improved, the structural strength of the first connecting member 1 is thus improved, and the service life of the first connecting member 1 is further extended. Among them, the second buffer member 126 is a rubber member, and the second buffer member 126 is directly vulcanized and installed on the lower side surface of the second cover plate 125.

[0062] According to some embodiments of the present invention, referring to Figure 3 , the yaw angle of the first connecting member 1 with respect to the central axis of the second connecting member 2 is β, where β satisfies: 0 < β ≤ 5°. For example, in Figure 3In the example, the first connecting member 1 yaws left or right relative to the second connecting member 2, and the yaw angle is β. When the shock absorber 201 drives the first connecting member 1 to swing, the first connecting member 1 swings along the arc-shaped side wall of the mating groove 11 with the center point of the ball head skeleton 21 as the center of motion, and the direction is opposite to the yaw direction of the shock absorber 201. The maximum swing angle of the ball head skeleton 21 is 5°, which can effectively reduce the influence of the lateral force generated by the yaw of the shock absorber 201. At the same time, the gap between the first connecting member 1 and the vehicle body 301 also ensures that there will be no movement interference and abnormal noise between the two due to yaw, thereby improving the service performance of the suspension system 200. In addition, the maximum yaw angle β of the first connecting member 1 relative to the central axis of the second connecting member 2 is greater than the yaw angle γ of the shock absorber 201, which can effectively eliminate the influence of the lateral force generated by the yaw of the shock absorber 201. The ball head skeleton 21 realizes the movable connection between the second connecting member 2201 and the shock absorber 201. Thus, when the wheel 303 of the vehicle 300 moves up and down, there can be a certain amount of movement between the second connecting member 2 and the shock absorber 201, thereby eliminating the lateral acting force received by the shock absorber 2. In addition, the connection assembly 100 is assembled by a variety of sub-components, with simple process and cost savings. The fasteners 3 connected to the vehicle body 301 are evenly installed, which can effectively avoid misinstallation.

[0063] According to a second aspect embodiment of the present invention, the suspension system 200, referring to Figure 3 , includes a connection assembly 100 for the suspension system 200 according to the above first aspect embodiment of the present invention.

[0064] According to the suspension system 200 of the present invention, by adopting the above connection assembly 100, the reliability of the use of the suspension system 200 is improved, and the service life of the suspension system 200 is also extended. Among them, the connection assembly 100 can be used for the suspension system 200 in front of the vehicle 300 or the suspension system 200 behind the vehicle 300. The connection assembly 100 has high versatility and is convenient to use.

[0065] According to some embodiments of the present invention, referring to Figure 3 , the suspension system 200 further includes a shock absorber 201 and an elastic component 202. The shock absorber 201 includes a cylinder block 2011 and a piston rod 2012. One end of the piston rod 2012 is arranged inside the cylinder block 2011, and the other end of the piston rod 2012 extends outside the cylinder block 2011. The elastic component 202 is arranged on the outer peripheral side of the shock absorber 201. The connection assembly 100 is respectively connected to the other end of the piston rod 2012 and the elastic component 202.

[0066] For example, in Figure 3In the example, the lower end of the piston rod 2012 is fitted inside the cylinder block 2011, the upper end of the piston rod 2012 extends outside the cylinder block 2011, passes through the second through hole 1251 and the first through hole 1211 of the connection assembly 100, and is tightly fitted with the first buffer member 124 of the connection assembly 100. The lower part of the elastic assembly 202 is sleeved on the outer peripheral side of the cylinder block 2011, and the upper end of the elastic assembly 202 is connected to the outer housing 122 of the connection assembly 100. With such an arrangement, the structure is simple, the assembly difficulty between the connection assembly 100 and the piston rod 2012 is reduced, and the installation efficiency is improved. In addition, the connection stability between the connection assembly 100 and the piston rod 2012 is also improved, and the service stability of the suspension system 200 is improved.

[0067] Among them, in the load force (such as Figure 4 shown), the first channel is that the upper end of the elastic assembly 202 is connected to the outer housing 122, and the spring force F1 of the elastic assembly 202 is transmitted separately. The second channel is that the second cover plate 125 and the second buffer member 126 are fixedly connected, and the buffer force F2 is transmitted separately. The third channel is that the first buffer member 124 is tightly connected to the piston rod 2012, and the shock absorber force F3 is transmitted separately. The connection assembly 100 designs a separate transmission path for each of the three major loads in the suspension system to transmit to the vehicle body 301, so as to meet the comfort of the vehicle 100, the smooth turning of the vehicle 100, and the high- and low-frequency vibration isolation performance, etc. Through the design of multiple channels, the impact force on the shock absorber 201 can be effectively reduced, the service life of the connection assembly can be improved, and the problems of failure, oil leakage, air leakage or abnormal noise can be avoided. In addition, the suspension system 200 is stressed through the cooperation of multiple channels, which improves the stability and reliability of the connection group 100, thereby improving the comfort, smooth turning and high- and low-frequency vibration isolation performance of the vehicle 300.

[0068] In terms of kinematic pairs, a spherical pair connection is adopted between the first connecting member 1 and the second connecting member 2, a sliding pair is formed between the piston rod 2012 and the cylinder block 2011, a sliding pair is also formed between the elastic assembly 202 and the cylinder block 2011, and a fixed pair is formed between the elastic assembly 202 and the connection assembly 100.

[0069] According to some embodiments of the present invention, with reference to Figure 4 and Figure 5 , the elastic assembly 202 includes an air spring component 2021 or a coil spring 2022. Thus, when the elastic assembly 202 is the air spring component 2021, the suspension system 200 is an air suspension. When the elastic assembly 202 is the coil spring 2022, the suspension system 200 is a MacPherson suspension, and the axes of the shock absorber 201 and the coil spring 2022 coincide and do not require eccentric arrangement. Thus, it is convenient to flexibly set according to the actual use situation, the use performance is improved, and the versatility of the connection assembly 100 is also improved. The elastic assembly 202 and the shock absorber 201 jointly determine the elastic movement of the suspension system 200.

[0070] According to some embodiments of the present invention, with reference to Figure 4 , when the elastic component 202 includes an air spring component 2021, the outer shell 122 of the connection component 100 is connected to the upper air chamber 2021a of the air spring component 2021. For example, in the example of Figure 4 , the outer shell 122 and the upper air chamber 2021a of the air spring component 2021 are connected by a fastener 3. And a sealing ring 14 is provided between the outer shell 122 and the upper air chamber 2021a to further enhance the connection tightness and prevent dust, water, oil, etc. outside the air spring component 2021 from entering the interior of the air spring component 2021, thereby improving the service performance of the air spring component 2021. The air spring component 2021 is of a single-chamber type. The air spring component 2021 further includes a first hoop 2021b, a clamping ring 2021c, a bladder 2021d, a protective shell 2021e, a second hoop 2021f, and a dust cover 2021g. The bladder 2021d is the core part of the air spring component 2021, having good elasticity and tightness, and can adjust the stiffness and suspension height of the air spring component 2021 by its own expansion and contraction. The bladder 2021d is sleeved on the outer peripheral side of the cylinder block 2011 of the shock absorber 201. The first hoop 2021b seals and presses the upper end of the bladder 2021d with the upper air chamber 2021a. The clamping ring 2021c connects the lower end of the bladder 2021d and the cylinder block 2011, preventing external air pressure from entering the interior of the air spring component 2021 during installation. The protective shell 2021e is sleeved on the outer peripheral side of the bladder 2021d to protect the bladder 2021d. The protective shell 2021e can be an aluminum alloy part, and the bladder 2021d can be a rubber part. The dust cover 2021g prevents dust and other impurities below the shock absorber 201 from entering the air spring component 2021. The second hoop 2021f connects the protective shell 2021e and the dust cover 2021g, and the connection is achieved by interference fit.

[0071] As Figure 5 shown, the included angle between the mating portion 211 and the piston rod 2012 is θ. The force F0 generated by the second connecting member 2 on the mating portion 211 of the first connecting member 1, the distance from the acting force to the axis of the piston rod 2012 is R, and the movement radius of the mating portion 211 is r. During the swinging movement of the mating portion 211, the frictional force f increases as F3 increases, and the generated frictional torque T is as follows:

[0072] The included angle θ and the distance R will vary within a certain range with the yaw angle β. When the frictional torque T is of an appropriate magnitude, it can offset or even completely offset the lateral force received by the shock absorber 201 during the movement of the suspension system 200, thereby enhancing the stability of the vehicle body 301 and strengthening the buffering effect of the suspension system 200. At the same time, the sealing performance and buffering performance of the air spring component 2021 can be improved, and the stability and reliability of the suspension system 200 can be enhanced.

[0073] According to some other embodiments of the present invention, referring to Figure 6 and Figure 7 when the elastic component 202 includes a coil spring 2022, one end of the coil spring 2022 is connected to the second cover plate 125 of the connection component 100.

[0074] For example, in the examples of Figure 6 and Figure 7 the coil spring 2022 and the shock absorber 201 are on the same axis, the upper mounting seat of the coil spring 2022 is integrally provided with the second cover plate 125, and a third buffer member (not shown in the figure) is sleeved on the piston rod 2012. Thus, the connection component 100 can be used in cooperation with the MacPherson suspension system, effectively eliminating the lateral force of the shock absorber 201, enabling the coil spring 2022 not to be eccentrically arranged, and extending the service life of the coil spring 2022.

[0075] As shown in Figure 10 point A is the upper point of the piston rod 2012, point B is the ground contact point of the wheel 302 of the vehicle 300, and point C is the connection point between the lower swing arm 303 and the steering knuckle 304 of the vehicle 300. W is the force exerted by the ground on the wheel 302, F C is the reaction force at point C, e is the distance between point B and point C in the direction perpendicular to the force exerted by the ground on the wheel 302, and L is the distance between point A and point C in the direction perpendicular to the reaction force at point C. The moment balance at point A is as follows:

[0076] Specifically, the moment balance at point A indicates that the moment generated during the movement of the wheel 302 is mainly balanced by the lower swing arm 303. The addition of the connection component 100 has significantly improved the lateral force generated by the shock absorber 201 during the up and down movement of the wheel 302. By optimizing the moment distribution, the connection component 100 can effectively reduce the influence of the lateral force on the suspension system 200. This improvement not only enhances the stability of the suspension system 200 but also significantly reduces the additional burden of the lateral force on the coil spring 2022 and the shock absorber 201, thereby extending the service life of the coil spring 2022.

[0077] When the vehicle 300 turns, the torque generated by the coil spring 2022 is transmitted to the connection assembly 100. The mating portion 211 of the ball head skeleton 21 can swing on the arc-shaped mating groove 11 formed between the outer housing 122 and the first cover plate 13. When the vehicle 300 steers, the first connecting member 1 and the second connecting member 2 of the connection assembly 100 rotate relative to each other, and the frictional torque T generated during the rotation can effectively cancel out all the spring torques of the connection assembly 100 during the steering of the vehicle 300, thereby improving ride comfort. Moreover, the structure of the connection assembly 100 is simple and the effect is remarkable.

[0078] The vehicle 300 according to the third aspect embodiment of the present invention, referring to Figure 8 and Figure 9 , includes a connection assembly 100 for the suspension system 200 according to the first aspect embodiment of the present invention above, or a suspension system 200 according to the second aspect embodiment of the present invention above.

[0079] In the vehicle 300 according to the present invention, by adopting the above connection assembly 100 and suspension system 200, the first connecting member 1 and the second connecting member 2 cooperate with each other, which can significantly reduce the lateral force received by the shock absorber 201, effectively improve the yaw stiffness, and thus extend the service life of the shock absorber 201 and the connection assembly 100. At the same time, it also significantly improves the stability, handling performance and noise, vibration and harshness (NVH) performance of the suspension system 200, providing a better driving experience for the vehicle 300. Among them, the vehicle 300 further includes a vehicle body 301, a wheel 302, a lower control arm 303, a steering knuckle 304 and a subframe 305. The vehicle body 301 is connected to the second connecting member 2 of the connection assembly 100 through a fastener 3. The wheel 302 is connected to the lower control arm 303 through the steering knuckle 304. The lower end of the suspension system 200 is connected to the upper end of the steering knuckle 304.

[0080] When the suspension system 200 is of the double-wishbone type, the vehicle further includes a double-wishbone 306. The inner point of the lower control arm 303 is connected to the subframe 305 through a bushing. The outer point of the lower control arm 303 is connected to the lower end of the steering knuckle 304 through a ball joint. The outer point of the lower control arm 303 is connected to the upper end of the steering knuckle 304 through a ball joint. The two inner points of the lower control arm 303 are connected to the vehicle body 301 through bushings and fasteners 3.
