Multi-link rear suspension, vehicle axle assembly and vehicle

Abstract

The invention relates to the technical field of automobiles, in particular to a multi-link rear suspension, a vehicle axle assembly and a vehicle. The multi-link rear suspension, the vehicle axle assembly and the vehicle aim to solve the problems of complex structure and large occupied chassis space of existing multi-link suspensions. To solve the problems, the multi-link rear suspension comprisesa damping mechanism, an elastic mechanism and a link assembly, wherein the link assembly comprises a first control arm, the two ends of the first control arm are connected with a steering knuckle andan auxiliary frame separately, the two ends of the damping mechanism are separately connected with the steering knuckle and a vehicle body, and the two ends of the elastic mechanism are separately connected with the first control arm and the vehicle body. A shaft hole allowing a wheel shaft of wheels to penetrate through is formed in the steering knuckle, the damping mechanism is located on one side of the shaft hole in the length direction of the vehicle, and the elastic mechanism is located on the other side of the shaft hole in the length direction. According to the multi-link rear suspension, the structure complexity of the multi-link rear suspension is greatly reduced, and the occupied space of the multi-link rear suspension is reduced.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a multi-link rear suspension, an axle assembly and a vehicle. Background technique [0002] With the rapid development of automobile technology, users have higher and higher requirements for the comfort and handling performance of vehicles. Suspension, as the core component of the automobile chassis, directly determines the handling performance and ride comfort of the vehicle, so the research and development of suspension is very important for major automobile manufacturers. Automobile suspension is divided into independent suspension and non-independent suspension. Multi-link suspension is a kind of independent suspension. Because it has multiple connecting rods and struts, each connecting rod can perform multiple functions on the wheel. Force control, so cars equipped with multi-link suspensions usually have excellent handling performance and ride comfort. [0003] Althou...
