Abstract:In today's society, automobiles have developed into people's daily transportation tools. Faster and more comfortable vehicles have become the research direction of automobiles in the future. Therefore, suspension systems have become people's primary research goals. This design takes the two-seater electric vehicle rear suspension as the research object. By comparing the advantages and disadvantages of the two types of suspension, the suspension type that is most suitable for the two-seater electric vehicle rear suspension is selected, and the non-independent suspension is used to achieve the purpose of simple manufacture, convenient maintenance and simple structure. The article calculates the elastic elements and shock absorbers of the rear suspension, determines and checks the specific values of the elastic elements and shock absorbers and other parts, to ensure that the calculated data meet the design requirements and makes use of CATIA modeling.

1 引言

在当今社会,汽车已经成为了人们出行的重要交通工具,悬架是汽车的重要总成之一,主要作用是传递力、导向和减震,因此悬架系统成为了人们首要的研究目标。

悬架是汽车上的重要组成部分。它由弹性元件、导向机构和减振器组成。汽车在行驶过程中,悬架可以通过减缓由于颠簸而引起的冲击力,悬架还可以迅速衰减由于弹性系统引起的振动,传递来自各个方向的力及其转矩,并起导向作用。

2 悬架系统的选择

两座电动汽车后悬架设计首先要满足其车身整体布局设计,其次还要具有制造简便、方便维修的特点[1]。根据两座电动汽车的设计要求,两座电动汽车需要有良好的导向作用,其结构要简单,使其制造成本降低,具有良好的承载能力,也要方便维修,最终选择整体桥式非独立悬架。……
