Automobil reduction final drive 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 ten meters passager car reduction final 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 .
Key words : Reduction final ; Differential ; Rotational speed ;Plantet gear ;Drive ratio
