Modularized elastic support, suspension system and automobile

Abstract

The invention relates to a modular elastic support, a suspension system and an automobile. The suspension system comprises the modular elastic support, a guide mechanism and a bearing part; the modular elastic support comprises an outer sleeve, an elastic body, an inner sleeve and two mounting wings; the outer sleeve is of a hollow cylindrical structure, and a plurality of mounting pairs are coaxially arranged on the outer surface of the outer sleeve in different radial directions; a plurality of mounting pairs are arranged in different radial directions; the elastic body is of a hollow structure and is mounted in the hollow cylindrical structure of the outer sleeve; the elastic body have different rigidity in different radial directions; the guide mechanism is adjustably mounted on one ofthe mounting pairs according to different rigidity requirements; the inner sleeve is of a hollow cylindrical structure, is sleeved in the elastic body and is coaxially arranged with the outer sleeveand the elastic body; one ends of the two mounting wings are rotatably mounted at the two ends of the inner sleeve respectively; therefore, the modular elastic support can be used for a plurality of automobiles with different performances, the structure is not easy to loosen, the installation is convenient, and the applicability is wide.

Description

technical field [0001] The application relates to the technical field of automobile chassis, in particular to a modular elastic support, a suspension system and an automobile. Background technique [0002] The suspension system of the automobile chassis is the entire support system composed of the spring between the body and the tire, the connection between the shock absorber and the frame; the main function of the suspension system is to transmit all the forces and moments acting between the wheel and the body, such as Supporting force, braking force and driving force, etc., and ease the impact load transmitted to the body from the uneven road surface, attenuate the vibration caused by it, ensure the comfort of the passengers, and reduce the dynamic load of the cargo and the vehicle itself. [0003] The suspension system of the automobile chassis is mainly composed of elastic elements, shock absorbers and guiding mechanisms. These three parts play the roles of buffering, vi...

AI Technical Summary

Problems solved by technology

[0004] The main problems of the above structure are: First, in terms of fastening and installation, the elastic bushing is clamped by the different directions of the bearing brackets on both sides. Since there is always a rebound force after the deformation of the bracket, if the tightening force of the fastener is not properly designed, During the continuous swing of the guide mechanism, this connection structure is prone to loose and abnormal noise, which affects the driving safety of the car; second, the rigidity of the elastic bushing in the installation direction is limited, and if it does not meet the performance requirements, it can only be scrapped as a whole. There is no modular design idea, which leads to the inability to reduce the cost of parts
