Design of drive axle in medium truck of Foton Aoling
摘要
本次设计是中型货车驱动桥的设计,驱动桥是汽车传动系统的重要部分,位于驱动链的末端,它的作用是提高转矩并将转矩传递到车轮和实现两车轮的差速功能.驱动桥作为汽车四大总成之一,它的性能的好坏直接影响整车性能,而对于载重汽车显得尤为重要.当采用大功率发动机输出大的转矩以满足目前载重汽车的快速、重载的高效率、高效益的需要时,必须要搭配一个高效、可靠的驱动桥.

Abstract
This is the design of the medium truck drive axle. The drive axle is an important component of the automotive transmission system, located at the end of the drive train.Its function is to increase the transmission shaft or transmission torque, passing it to the drive wheel and making it have a differential function. Driving axle as one of the four major assembly car, its performance is a direct impact on vehicle performance, for the truck is particularly important. Using high-power engine output torque to meet the current fast, heavy load of high-efficiency, high efficiency needs,which must be with a highly efficient and reliable drive axle.
