摘要近几年电动汽车正飞快的进步和发张，而电动客车在商用车这一领域中更是得到了很大的普及。目前，在街上我们可以看到很多电动公交。在普通汽车上，悬架系统是很特殊，很重要的一部分，它对于汽车的乘坐舒适性,操纵稳定性以及行驶安全性都有着特别重大的影响。在电动客车上同样如此，电动客车虽然没有内燃机，而是靠电机驱动，但是悬架还是和常规汽车基本相同，汽车悬架可以分为独立悬架和非独立悬架。现代汽车由于舒适性和操作性的需要，一般前悬架均采用独立悬架。此次设计的电动客车前悬架，则采用了麦弗逊式独立悬架，本次设计主要是对于悬架进行设计计算，并进行二维，三维建模，进行校核计算。使悬架满足电动客车的要求。主要对悬架的主要参数，极其主要零件进行设计。77717

Title The design of suspension system for electric bus 

Abstract Electric vehicles develop very fast in recent years。 Electric bus in the field of commercial vehicles has been a lot of popularity。 In normal vehicles, the suspension system plays a very important role in the vehicle。 It has a very important role in the car ride comfort, handling stability and driving safety。 The same is true on an electric bus。 Although the electric car does not have an internal combustion engine, but by motor drive, but the suspension is still the same as the conventional car。 Automotive suspension can be pided into independent and non-independent suspension。 Due to the comfort and operational requirements of the modern car, the general front suspension is independent of the suspension。 The design of the electric bus front suspension, then using the Macpherson independent suspension。The design is mainly for the suspension of the design and calculation, and two-dimensional, three-dimensional modeling, to check the calculation。 To make the suspension meet the requirements of electric bus。 The main parameters of the suspension, elastic components, shock absorber, guide mechanism, the design of the horizontal stabilizer bar。

KeywordsMacpherson independent suspension，springs，Shock absorber, Guiding mechanism,  Anti-roll Bar
