[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-Figure 10As shown, a suspension assembly includes a left suspension, a right suspension and a rear suspension. The left suspension and the right suspension have the same structure and are both side plug type double-layer hydraulic structures. The left suspension is connected to the gearbox, the subframe and the vehicle body, which can provide stable Z-direction support for the gearbox, and attenuate the vibration between the subframe and the gearbox in the X and Z directions, provide a relatively stable working environment, and extend the service life of components. The right suspension is connected to the engine, the subframe and the vehicle body, which can provide stable Z-direction support for the engine, and attenuate the vibration between the subframe and the engine in the X and Z directions, provide a relatively stable working environment, and extend the service life of components.

[0026] The left suspension and the right suspension both include a support bracket 100 and a support arm 200. The support arm 200 is fixedly installed in the support bracket 100 through a rubber main spring 300. The rubber main spring 300 forms a hydraulic chamber in the lower half of the support bracket 100. The hydraulic chamber is filled with ethylene glycol. A flow channel assembly 400 is arranged in the hydraulic chamber. A leather cup 600 is fixedly installed at the bottom of the support bracket 100. The cross section of the leather cup 600 is wavy. A leather cup cover plate 700 is arranged below the leather cup 600. An anti-collision pad 900 is fixedly installed on the front side of the top of the support bracket 100. The anti-collision pad 900 prevents the support arm 200 and the support bracket 100 from directly colliding.

[0027] When in use, the flow channel assembly 400 includes a partition plate 401, a boss 402 is provided on the top of the partition plate 401, and a plurality of first flow ports 403 are formed on the boss 402, and a connecting groove 404 is formed on the partition plate 401 located in front of the boss 402. A mounting cover 405 is attached to the bottom of the partition plate 401, a groove 406 is formed in the middle of the mounting cover 405, and a plurality of second flow ports 407 are formed on the bottom wall of the groove 406, and the first flow ports 403 correspond to the second flow ports 407 one by one. An annular flow channel 408 is formed on the top of the mounting cover 405, and the annular flow channel 408 surrounds the outer side of the groove 406, and one end of the annular flow channel 408 is connected to the connecting groove 404, and the other end of the annular flow channel 408 penetrates to the bottom of the mounting cover 405, and the partition plate 401 covers the top of the annular flow channel 408. Therefore, under the action of vibration, the support arm 200 drives the rubber main spring 300 to deform, thereby squeezing the ethylene glycol inside the hydraulic cavity, causing the ethylene glycol to flow back and forth through the annular flow channel 408, and under the action of hydraulic pressure, the leather cup 600 is bent and deformed. In practice, a liquid injection port 409 is provided in the middle of the front side of the mounting cover 405, and the liquid injection port 409 is connected to the annular flow channel 408. A steel ball 500 is provided inside the liquid injection port 409, and ethylene glycol can be injected into the hydraulic cavity through the liquid injection port 409, and the liquid injection port 409 is sealed by the steel ball 500. A filter plate 410 is embedded in the embedded groove 406.

[0028] Specifically, the rear suspension assembly is connected with the gearbox and the subframe, which can provide stable Z-direction support for the gearbox, and attenuate the vibration between the subframe and the gearbox in the Y and Z directions, provide a relatively stable working environment, and extend the service life of the components. The rear suspension includes a main spring exoskeleton 1000, the right half of the main spring exoskeleton 1000 is in a square frame shape, the left half of the main spring exoskeleton 1000 is in a "one" shape, a bushing assembly 1100 is provided through the left half of the main spring exoskeleton 1000, a main spring inner frame 1200 is provided in the right half of the main spring exoskeleton 1000, and a main spring rubber body 1300 is fixedly installed between the front and rear sides of the main spring inner frame 1200 and the inner wall of the main spring exoskeleton 1000.

[0029] In reality, the bushing assembly 1100 includes a bushing rubber body 1102, a bushing inner frame 1101 is fixedly installed on the inner side of the bushing rubber body 1102, a bushing outer frame 1103 is fixedly installed on the outer side of the bushing rubber body 1102, and the bushing outer frame 1103 is fixedly installed in the left end of the main spring outer frame 1000. The bushing rubber body 1102 is fixed to the bushing inner frame 1101 and the bushing outer frame 1103 by vulcanization. The main spring inner frame 1200 is A-shaped, and a mounting hole 1201 is opened through the right half of the main spring inner frame 1200, and four hollow holes 1202 are opened through the left half of the main spring inner frame 1200, so that the hollow holes 1202 are more lightweight.

[0030] The third rubber bumps 1203 are fixedly installed at both ends of the main spring inner frame 1200, the first rubber bump 1001 is fixedly installed on the right inner wall of the main spring outer frame 1000, and the second rubber bump 1002 is fixedly installed on the left inner wall of the main spring outer frame 1000. The two third rubber bumps 1203 are opposite to the first rubber bump 1001 and the second rubber bump 1002 respectively. During the vibration process, the main spring inner frame 1200 moves left and right, and the main spring rubber body 1300 will deform, and the main spring rubber body 1300 will provide resistance to the vibration of the main spring inner frame 1200. In this process, the third rubber bump 1203 will collide with the first rubber bump 1001 and the second rubber bump 1002. The main spring inner frame 1200 is further limited.
