BJ2022 car single stage and the structure of the main reducer

differential design and strength analysis

ABSTRACT

Automobil reduction final drive and differential is one of the best impossible parts in automobile gearing. It can chang speed and driving tuist within a big scope .

The problem of this design is BJ2022 car differential unit ,it¡¯ s properly in common use . The design of scheme, the better design and improvement of structure ,the design and calibration of gear and gear shiftes , and the select of bearings , and also the design explain the construction of differential action .

The ting of the scheme desierment main deside. The drive ratio of gear,according to orginal design parameter and constrasting the same type

reduction final drive ang differential assay . It realize planet gear in the design of structure . It put to use alteration better gears transmission in the design of gear , and compare the root contact tired strength of some important gears and the face twirl tired strength . It eraphaize pay attention to the place of gears. Compare the strength of the biggest load dangraes section. It require structure simple and accord with demand in select of bearings .

The Lord reducer to improve the car driving and differential stability and its through sex , is one of the focal points of automotive design. Key words : Drive axle,Main reducer,Differential,Axle
