介绍了CA141型汽车后桥的结构型式和主要参数,指出了使用维修时应注意的问题。一、后桥的结构型式和主要参数CA141型汽车后桥总成如下图所示。它的后桥外壳为整体式,从两端压人半轴套管,后桥外壳与外壳盖用螺栓联接。半轴为全浮式。采用双级减速传动装置,第一级为螺旋锥齿轮传动副,第二级为斜齿圆柱齿轮传动副,改变齿轮的齿数和某些参数之后,可得到四种速比的后桥,如表1所示 The structure type and main parameters of CA141 rear axle are introduced, and the problems that should be paid attention to when using and repairing are pointed out. First, the structure and the main parameters of the rear axle CA141-type automobile rear axle assembly as shown below. Its rear axle housing is a one-piece, half man shaft sleeve pressured from both ends and bolted to the rear axle housing and housing cover. Half shaft is full floating. The use of two-stage reduction gear, the first level for the spiral bevel gear drive, the second stage for the helical gear drive, change the gear teeth and some parameters, you can get four speed ratio of the rear axle, as the table 1 shown
