Background
In automobile parts, a suspension device is one of important components, and the quality of the working performance of the suspension device directly influences the aspects of automobile vibration, impact, noise and the like. The main functions of the suspension are as follows: 1. supporting the power assembly and determining the position of the power assembly; 2. controlling the power assembly to move; 3. isolating the power assembly vibration; 4. as an additional shock absorber, the shock absorber attenuates the vibration of the suspension, which is caused by the uneven road surface, and is transmitted to the vehicle body; 4. bearing the output torque and dynamic load of the power assembly.
Generally, one end of the suspension is connected with a vehicle body or a sub-frame through an outer bracket, the other end of the suspension is connected with a power assembly through a supporting arm, and the supporting arm is elastically connected with the outer bracket through a main rubber spring.
When the automobile causes low-frequency large-amplitude vibration during running, in order to attenuate the engine vibration caused by the excitation of the road surface as soon as possible, the engine mount should have a large damping characteristic; in order to reduce the vibration transmitted to the frame or the vehicle body by the excitation of the engine when vibrating at high frequency and small amplitude, the engine mount should have a small stiffness and a small damping characteristic. However, the common rubber suspension is difficult to meet the requirements, and the passive hydraulic suspension with the liquid damping mechanism added on the basis of the rubber structure has good frequency amplitude change characteristics, so that the hydraulic suspension is gradually and widely applied to medium-high-grade cars at present.
