Abstract

The invention relates to an elastic multi-link linear guide independent suspension which comprises a wheel, a frame, a spring shock absorber system and a steering knuckle, wherein the steering knuckle is connected with the wheel through a hub unit, and the spring shock absorber system is respectively connected with the steering knuckle and the frame through a bulb pair. The suspension also comprises four strip plate shaped elastic anisotropic members, wherein longitudinal axial lines of the first member at the upper side of the suspension and the first member at the lower side of the suspension are in a vertical plane, longitudinal axial lines of the second member at the upper side of the suspension and the second member at the lower side of the suspension are in the same vertical plane, and the two vertical planes are not parallel. The elastic multi-link linear guide independent suspension has the advantages of being capable of restraining the wheel to ensure that the wheel is always in the same straight line during bobbling, effectively reducing the abrasion of a tyre, and being capable of effectively improving control stability, the running smoothness and the riding comfort of the vehicle, and also has the remarkable advantages of simple structure, strong designability, convenience for assembly and regulation and the like.

Description

technical field [0001] The invention relates to an automobile suspension system, in particular to an elastic multi-link linear guide independent suspension. Background technique [0002] Suspension is a general term for devices that ensure the elastic connection between the wheel or axle and the vehicle's load-carrying system (frame or load-bearing body) and can transmit loads, ease shocks, attenuate vibrations, and adjust the position of the vehicle body during driving. Generally, the suspension is mainly composed of three parts: elastic elements, shock absorbers and guide mechanisms. In some cases, a certain component plays two or three roles, such as a leaf spring that also acts as an elastic element and a guiding mechanism. The function of the guide mechanism is to ensure reliable transmission of all forces and moments between the wheel and the body or frame, and to determine the displacement characteristics of the wheel relative to the body or frame. The guiding mecha...
