Its function is used in different conditions, changes to the drive wheels on the engine torque ancd rotational speed, make cars get different traction and the engine speed, and at the same time at the most favorable conditions range work. Through the jetta car transmission design, make its transmission better performance has certain practical significance. I designed the transmission main contents: 1. The transmission of the overall plan is affirmatory. The function and requirement of the transmission determined to structure plan, and the structure of main parts and the transmission scheme analysis. 2. The main parameter selection and transmission of main parts design. Of the transmission main parameters of each gear transmission choice, and determine the pinion gear, gear edge position coefficients choice. 3. Transmission gear strength calculation and material selection. The damage of gear determination of reason and form of gear, strength calculation and checking. 4. Transmission shaft strength calculation and checking. Transmission shaft structure and size of the calculation and shaft dynamicrigidity. 5. Transmission synchronizer design and operation. The structure of synchronizer determination of synchronizer synchronous ring, main parameter is determined, the transmission of the choice and determination of manipulated
