And the transmission is the core part of the car, its development is particularly important. In the design of the automobile transmission, the transmission ratio of each file is firstly determined.. According to the known data, the gear ratio of the gear is determined by the formula, the tooth number, the pitch circle diameter and the choice of spur gears or helical gears. Shaft design. The two forms of transmission. After the data are well determined, the strength of the designed parts will begin to check.. And the design of the synchronizer, and behind of self-locking device, interlocking device design and reverse gear lock. The rapid development of the car makes the technology of its components higher.. However, it is necessary to put forward that as the core part of the transmission system, its manufacturing level, technological level, but also the need for peoples gaze. Its
