Embodiment Construction

[0025] The present invention will be described in detail below according to the accompanying drawings, which is a preferred embodiment among various implementations of the present invention.

[0026] The toe-in adjustable torsion beam suspension of the present invention includes two trailing arms, a beam, two toe-in control rods and other main components, and the components are connected by bushings. The specific structure is as figure 1 shown. figure 2 and image 3 is the dynamic simulation result of the suspension, figure 2 is the longitudinal flexibility curve, image 3 is the lateral force steering curve. From figure 2 It can be seen that after adopting this kind of suspension structure, the longitudinal flexibility has been greatly improved and can almost double the initial longitudinal flexibility, so that good ride comfort can be obtained; from image 3 It can be seen that the lateral force steering of the suspension has also been significantly improved, so tha...

Abstract

The invention relates to an adjustable toein torsion beam suspension and a forming method thereof. The suspension comprises a toein control rod and a dragging arm, wherein the toein control rod is connected to a vehicle body by a first liner and is connected with a third liner by a dragging arm; due to a small improvement on the structure of a common torsion beam, the longitudinal flexibility and the lateral steering performance of the suspension are improved considerably; and the improved suspension realizes high performance under a condition of low cost.

Description

technical field [0001] The invention relates to a toe-in adjustable torsion beam suspension which can improve suspension performance such as lateral force steering and longitudinal flexibility compared with a common torsion beam rear suspension, in particular to an adjustable toe-in torsion beam suspension Frames and how they are constructed. Background technique [0002] The torsion beam suspension is widely used in the rear suspension of automobiles due to its simple structure and low cost. In middle and high-end cars, independent suspensions such as multi-links are used to achieve better handling stability. It can realize precise control on the toe angle and camber angle of the wheel, so that the dynamic performance of the whole vehicle is obviously better than that of the torsion beam rear suspension. As an important part of the car, the suspension plays a very important role in the handling stability and smoothness of the vehicle. In the design of the rear suspension, ...
