基于独立悬架的客车底盘升级

摘要

Suspension is one of the important assembly about modern vehicle,which puts frame and axle join up Elastic flexibly.Its maintask is to transfer function of all the force and moment between the wheel and frame,and alleviate the impact load which transfers to frame from uneven pavement,all of which to ensure the normal operation of vehicle.And adopting independent suspension can reduce the spring load part weight greatly,reduced vibration load,So improved vehicle running smoothness. Before,the use of passenger car suspension generally adopt a dependent suspension.As people pay attention to ride comfort, control stability,running smoothness,the original suspension system already cannot satisfy the requirement of people.Faw bus (chengdu)company devotes to improve passenger car quality and increase passenger car products market share.Now this paper is upgrading chassis of CDL6606 model,changes the original plate spring suspension into that the front suspension adopts double wishbone type independent suspension and the rear suspension uses little leaf spring suspension.%悬架是现代汽车的重要组成之一，它把车架（或车身）与车轴（或车轮）弹性地连接起来。其主要任务是传递作用在车轮和车架之间的一切力和力矩，并且缓和由不平路面传给车架的冲击载荷，衰减由冲击载荷引起的承载系统的振动，以保证汽车的正常行驶。而采用独立悬架可大大减轻非簧载部分重量，减轻了振动载荷，所以改善了汽车的行驶平顺性。以往客车悬架的使用普遍都采用非独立悬架，随着人们对乘坐舒适性、操纵稳定性、行驶平顺性的重视，原有悬架系统已不能满足人们的要求，为满足市场需要，一汽客车（成都）公司致力于改善客车品质、增加产品市场占有率，本文对 CDL6606车型进行底盘升级，将原有前后钢板弹簧悬架改为，前悬架采用双横臂式独立悬架，后悬架采用少片簧悬架。
