摘要
本说明书阐述的内容是关于低速载货汽车驱动桥总成设计和计算过程。驱动桥是汽车行驶系的重要组成部分,其基本功用是增大由传动轴或直接由变速器传来的转矩,将转矩分配给左、右车轮,并使左、右驱动车轮具有汽车行驶运动学所要求的差速功能。所以其设计质量直接关系到整车性能的好坏。所以在设计过程中,设计者本着严谨和认真的态度进行设计。在方案论证部分,对驱动桥及其总成结构形式的选择作了具体的说明。本设计选用了单级减速器,采用的是螺旋锥齿轮啮合传动,尽量的简化结构,缩减尺寸,有效的利用空间,充分减少材料浪费,减轻整体质量。由于是轻型货车,主要是在路面较好的条件下行驶,因此没有使用差速锁。在设计计算与强度校核部分,对主减速器主从动齿轮、差速器齿轮、半轴和桥壳等重要部件的参数作了选择。同时也对以上的几个部件进行了必要的校核计算。最后,根据所选参数绘制工程图。

Abstract
This manual describes the content of the assembly process of analysis and design of low-speed truck drive axle. Drive axle is an important part of the vehicle driving system, its basic function is to increase the drive shaft or transmission came directly from the torque, the torque distribution to the left, right and left, right wheel, to drive the wheels with the car driving kinematics required differential function. So the design quality is directly related to vehicle performance. So in the design process, the designer in the rigorous and serious attitude design. In the part of demonstration program, the drive axle and its assembly structure form selection for specific instructions. This design uses a single-stage reducer, adopts the meshing of spiral bevel gears, it can simplify the structure, reduce the size, effective space utilization, to reduce material waste, to reduce the overall quality. Because it is a light truck, is running in good condition under the road, so there is no use differential lock. In the design calculation and strength check parts, parameters of the main reducer driven important parts of gear, gear, axle and axle housing, made a choice. At the same time also to several parts above the necessary to check the ,I draw. the Engineering drawings according to the selected parameter
Keywords:Drive axle;The main reducer;Design;Parameter selection.
