Abstract
The rear axle assembly of LGV also been named drive axle, Mainly by the main reducer, differential and axle, and drive components, such as Shell Bridge.
Reducer is the main vehicle of transmission in reducing speed and increase torque of the main components. Reducer the main structure of the design parameters and in addition to the car's reliability and durability have an important influence, the car will have a direct impact on performance.
In this paper on the rear axle the main reducer the design, calculation and the main parameters of strength checking parts. First ，I introduce the choice of the main topics on the background of significance on this issue to be resolved the major issues, to achieve the desired objectives at home and abroad as well as the development of automobile axles. Then, I talked about the main type of reducer, the main reducer the type and the main gear reducer type of support and resettlement method. Then the main reducer parameters and design, the choice of the basic parameters for the next step to prepare for the calculation, the next is the bevel gear reducer is the main strength and bearing the load calculation.
Through known about the main reducer awareness and understanding ，so that I gained a deeper impression on the axles of the car ，it may be gave me a large help for how to buy cars in the future,and how to optimize the design of the car better .
Key words: Main Reducer Design Intensity Examination
