DETAILED DESCRIPTION

[0017] The following is combined with Figure 1 -Attached Figure 5 , further details of this application are given.

[0018] An automobile suspension assembly, referring to Figure 1 , including a torsion beam body 1, a mounting bracket 6, a cantilever 7, a brake disc body 8, a spring seat 5, a coil spring 4, a clamping assembly 3, a support plate 11, a shock absorber body 9, a buffer block body 10 and a protective assembly 2. There are two mounting brackets 6, one end of each of the two mounting brackets 6 is fixedly connected to one end of the torsion beam body 1. The arrangement of the mounting bracket 6 is convenient for connecting the automobile suspension assembly to the vehicle body. There are two cantilevers 7. The outer surfaces of the two cantilevers 7 are rotatably connected to the inner wall of the torsion beam body 1 through a rotating shaft, so that the cantilever 7 can rotate flexibly relative to the torsion beam body 1. There are two brake disc bodies 8, one end of the two brake disc bodies 8 is respectively hinged to one end of the two cantilevers 7 through a rotating shaft to ensure that the wheels can be effectively braked during braking. One end of the spring seat 5 is fixedly connected to one end of the cantilever 7, and the coil spring 4 is movably connected to the lower inner wall of the spring seat 5. The coil spring 4 plays a buffering role and clamps The component 3 is arranged on the outer surface of the spring seat 5. The arrangement of the clamping component 3 enables the coil spring 4 to be firmly installed in the spring seat 5 to prevent the coil spring 4 from shifting in the spring seat 5. One end of the support plate 11 is fixedly connected to one end of the cantilever 7. The bottom end of the shock absorber body 9 is fixedly connected to the top end of the support plate 11. The shock absorber body 9 can absorb and consume the energy of the spring rebound during vehicle driving, reduce the vibration of the vehicle body, and improve the driving stability and comfort. The bottom end of the buffer block body 10 is fixedly connected to the output end of the shock absorber body 9, and the outer surface of the buffer block body 10 has strong elasticity. When encountering a large impact, the highly elastic buffer block body 10 can play a further buffering role. The protective component 2 is arranged on the outer surface of the shock absorber body 9. The protective component 2 effectively protects the shock absorber body 9 to prevent mud and sand from entering the shock absorber body 9 and affecting its normal use.

[0019] Reference Figure 2 and Figure 3 and Figure 4, the protective component 2 includes a protective cover body 21, an elastic layer 24, a heat dissipation layer 23, a wear-resistant layer 22, a first connecting ring 28, a second connecting ring 27, a connecting piece 25 and a connecting bolt 26. The protective cover body 21 is movably sleeved on the outer surface of the shock absorber body 9, and the protective cover body 21 plays a protective role. The elastic layer 24 is fixedly sleeved on the outer surface of the protective cover body 21. The elastic layer 24 serves to absorb and buffer vibrations and impacts from the outside world. The elastic layer 24 is a synthetic rubber foam material, which reduces the impact of instantaneous impact on the shock absorber and can maintain stable buffering performance under long-term vibration conditions. The heat dissipation layer 23 is fixedly sleeved on the outer surface of the elastic layer 24. The heat dissipation layer 23 can help dissipate the heat generated by the shock absorber during operation. The heat dissipation layer 23 is an aluminum foil material with a high thermal conductivity, which can effectively conduct the heat generated by the shock absorber and improve the heat dissipation efficiency. The wear-resistant layer 22 is fixedly sleeved on the outer surface of the heat dissipation layer 23. The wear-resistant layer 22 is a wear-resistant rubber material. 22 can effectively protect the shock absorber body 9 from these direct external force impacts, and the outer surface shapes of the protective cover body 21, the elastic layer 24, the heat dissipation layer 23 and the wear-resistant layer 22 are all bellows-shaped. At the same time, the shape setting can better adapt to the telescopic movement of the shock absorber body 9 during operation. The top of the first connecting ring 28 is fixedly connected to the bottom end of the protective cover body 21, and the inner wall of the second connecting ring 27 is fixedly connected to the outer surface of the shock absorber body 9. The connecting member 25 is movably clamped on the outer surface of the first connecting ring 28 and the second connecting ring 27. The inner wall shape of the connecting member 25 is "U"-shaped. The first connecting ring 28 and the second connecting ring 27 are conveniently connected together through the connecting member 25, so that the protective cover body 21 is installed on the shock absorber body 9. The connecting bolt 26 is threadedly connected to the top of the connecting member 25 and the inner wall of the first connecting ring 28 and the second connecting ring 27. The setting of the connecting bolt 26 makes the connection more stable, so that the protective component can better protect the shock absorber body 9.

[0020] Reference Figure 5 The clamping assembly 3 includes a mounting plate 33, a connecting plate 31 and a clamping sleeve 34. One end of the mounting plate 33 is fixedly connected to the outer surface of the spring seat 5, and the top of the mounting plate 33 is fixedly connected to the telescopic gas rod 32. The mounting plate 33 provides a mounting position for the telescopic gas rod 32, and the output end of the telescopic gas rod 32 is fixedly connected to one side of the bottom end of the connecting plate 31, so that the output end of the telescopic gas rod 32 drives the connecting plate 31 to move, and the inner wall of the clamping sleeve 34 is fixedly connected to the outer surface of the connecting plate 31, so that one end of the connecting plate 31 drives the clamping sleeve 34 to move, and the inner wall shape of the clamping sleeve 34 matches the outer surface shape of the coil spring 4, and the bottom end of the clamping sleeve 34 is movably engaged with the top of the spring seat 5, so that the inner wall of the clamping sleeve 34 is tightly fitted with the coil spring 4, ensuring the stability of the coil spring 4 in the spring seat 5 and preventing the spring from jumping or shifting.

[0021] The implementation principle of the embodiment of the present application is: first, the entire suspension assembly is installed on the vehicle chassis through the mounting bracket 6.

[0022] Then, the telescopic gas rod 32 is started through the compression assembly 3, and its output end drives the connecting plate 31 to move up and down, thereby causing the compression sleeve 34 fixedly sleeved on the outer surface of the connecting plate 31 to compress the coil spring 4 to prevent the coil spring 4 from shifting in the spring seat 5.

[0023] The cantilever 7 can rotate relative to the torsion beam body 1 around the rotating shaft. When the vehicle needs to brake, the braking system applies braking force to the brake disc body 8, and transmits the braking force to the wheels through the cantilever 7 to achieve vehicle deceleration and parking.

[0024] At the same time, after the vehicle passes through a bumpy road, the coil spring 4 absorbs and stores energy through its own elastic deformation, the shock absorber body 9 can quickly attenuate the vibration of the spring and reduce the up and down shaking of the vehicle body, and the buffer block body 10 further absorbs and buffers the remaining impact force through its own elastic deformation.

[0025] At the same time, through the protective component 2, the first connecting ring 28 at the bottom end of the protective cover main body 21 and the second connecting ring 27 fixedly sleeved on the outer surface of the shock absorber body 9 are movably clamped through the connecting piece 25, and are fixed with connecting bolts 26 to ensure a tight connection between the protective component 2 and the shock absorber body 9.

[0026] The protective cover body 21 is movably sleeved on the outer surface of the shock absorber body 9 to form a first protective barrier, which can prevent dust, mud, water and other impurities from entering the shock absorber. The elastic layer 24 can absorb and buffer part of the energy, reducing the impact force transmitted to the shock absorber body 9.

[0027] The heat dissipation layer 23 can help dissipate the heat by increasing the contact area with the outside air, thereby improving the heat dissipation efficiency. The wear-resistant layer 22 can prevent the protective cover body 21 from being damaged by scratches, wear and tear from external objects, thereby providing better protection for the shock absorber body 9.

Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
