摘要
本次设计是以东风牌LZ1090D载货汽车主要性能参数为依据来完成其驱动桥的设计。汽车驱动桥是汽车传动系中的重要组成部分,它主要由主减速器、差速器、半轴和桥壳等组成。其主要作用是降低转速、增大转矩,以及实现汽车行驶运动学所要求的差速功能,并且还要承受作用于路面与车架或车身之间的垂直力、纵向力和横向力等。
本设计利用给出的数据对驱动桥各零件的参数进行了计算确定,对驱动桥各主要部件进行了结构设计和校核计算。利用AutoCAD绘制了驱动桥零件及总成的二维图,利用CATIA软件对驱动桥进行了三维建模,并用CATIA软件中的数字化装配模块,对三维模型进行了直路和弯路两种行驶条件下的运动仿真,最后利用ABAQUS软件对驱动桥壳的受力进行了有限分析。
