vehicle suspension

Abstract

The invention provides an automobile suspension which comprises a frame, an axle and wheels. Elastic elements are arranged between the frame and the axle, a damping device is arranged on the frame, longitudinal draw bars are arranged on the axle, the elastic elements are rubber springs, each rubber spring comprises a clamp seat, a connecting screw and a rubber body, each connecting screw is arranged in the center of the corresponding clamp seat, each rubber body is sleeved on the corresponding connecting screw and comprises cylinders which are sleeved on one another layer by layer, and the radius of each inner-layer cylinder is smaller than that of the corresponding outer-layer cylinder. The automobile suspension has the advantages that the automobile suspension is provided with the conical rubber springs and has lateral and transverse bearing capacity, accordingly, lateral draw bars required by the traditional suspension can be omitted, the strength of longitudinal draw bars of an existing suspension can be reduced, and the longitudinal draw bars of the existing suspension can be lightened; inner and outer metal shaft sleeves and rubber bodies of rubber bushings which are arranged at upper and lower ends of dampers are of spherical structures, so that the automobile suspension can have a large deflection angle and a large twist angle and is high in bearing capacity, and abrasion to the rubber bodies of the bushings can be reduced.

Description

technical field [0001] The invention relates to the technical field of automobile suspension, in particular to an automobile suspension mechanism with conical rubber springs. Background technique [0002] The car suspension is one of the important assemblies on the car. Its main task is to transmit all the forces and moments acting between the wheels and the frame (or body), and to ease the impact load transmitted to the frame (or body) by the road. Attenuate the vibration caused by this to ensure the smooth running and handling stability of the car. [0003] There are many types of car suspensions, among which single trailing arm coil spring suspension is a commonly used rear suspension mechanism on small cars. Single trailing arm coil spring suspension includes metal coil springs, shock absorbers, shock absorber beams, longitudinal tie rods, transverse tie rods, etc. The upper and lower ends of the coil spring are respectively connected with the vehicle body (or vehicle ...

AI Technical Summary

Problems solved by technology

At the same time, the traditional suspension mechanism also has problems such as the heavy design of the shock absorber beam and the early wear of the shock absorber rubber bushing.

In addition, the traditional single trailing arm suspension mechanism has problems such as the rigidity change curve of the metal coil spring is difficult to match the actual driving conditions, the number of parts is large, and the self-weight of the suspension system is too large.
