Multi-link rear suspension, axle assembly and vehicle

Abstract

The invention relates to the technical field of automobiles, in particular to a multi-link rear suspension, an axle assembly and a vehicle. The invention aims to solve the problems of complex structure and large chassis space occupied by the existing multi-link suspension. For this purpose, the multi-link rear suspension of the present invention, the multi-link rear suspension includes a shock absorbing mechanism, an elastic mechanism and a connecting rod assembly, and the connecting rod assembly includes a first control arm, the two ends of the first control arm are respectively connected to The steering knuckle is connected with the sub-frame, the two ends of the damping mechanism are respectively connected with the steering knuckle and the vehicle body, and the two ends of the elastic mechanism are respectively connected with the first control arm and the vehicle body, and the steering knuckle is provided with a shaft allowing the wheel axle to pass through The shock absorbing mechanism is located on one side of the axle hole in the longitudinal direction of the vehicle, and the elastic mechanism is located on the other side of the axle hole in the longitudinal direction. The invention greatly reduces the structural complexity of the multi-link rear suspension and reduces the occupied space of the multi-link rear suspension.

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...
