Separation buffering type shock absorber strut and automobile

Abstract

The invention relates to a separation buffering type shock absorber strut and an automobile. The separation buffering type shock absorber strut comprises a helical spring, a buffering stopper, a shock absorber, a front suspension combined part, an upper spring seat and a plane bearing, wherein the front suspension buffering combined part consists of a bottom-end connecting plate and a top end connecting plate, an inner connecting plate is disposed in a holding cavity, the buffering stopper is sleeved on the shock absorber, the bottom-end connecting plate is provided with an avoidance through hole, the shock absorber penetrates through the avoidance through hole to be connected with the inner connecting plate, and the top end of the plane bearing is connected with the bottom end of the bottom-end connecting plate. The invention further provides an automobile. The separation buffering type shock absorber strut and the automobile have the advantages that an elastic force transmission path, a buffering limiting force transmission path and a damping force transmission path are well separated, accordingly, optimal riding comfort and maneuverability are realized, the working radius of the plane bearing is increased, and stability is improved.

Description

technical field [0001] The invention relates to the configuration of a vehicle suspension device, in particular to a separate buffer type shock absorber pillar in the configuration of the vehicle suspension device and an automobile. Background technique [0002] At present, the front suspension system of most small passenger cars adopts a MacPherson shock absorber strut (hereinafter referred to as "strut"), which serves as a suspension guide rod system and also has the functions of supporting the body and damping vibration. [0003] like figure 1 and figure 2 As shown, the pillar product structure used is mainly composed of elastic and damping parts such as coil spring 1, buffer limit block 2 and shock absorber 3, as well as spring upper seat 5, plane bearing 6, front suspension buffer assembly 4, front suspension support 401, etc., and are rigidly connected to the vehicle body through the front suspension support 401. [0004] The transmission paths of various forces on...

AI Technical Summary

Problems solved by technology

The three forces have different requirements on the dynamic and static characteristics of the buffer, but the front suspension buffer assembly 4, as a common buffer, cannot meet the respective dynamic and static characteristics at the same time, thereby reducing ride comfort and handling

[0010] 2) The working radius of the plane bearing is limited by the structure, so only plane bearings with smaller specifications can be used, and the structural stability is poor
