ABSTRACT
The jetta cars used widely in our country, and the key is the vehicle transmission is one of the assembly. 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.
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 mechanism.
