Drivetrain is the ponents of task is transforming and regulateing the performance of engine. Transmission can effectively and economically conveyed the power to the wheel which can meet the requirement of vehicles. It is used to change the engine's torque spread and wheel speed. Aim is to work ina variety of conditions , different vehicle traction and speed , so that the car has good power and fuel economy 。 The transmission of the structure of the manipulation of car shift required reliability and portability, transmission stability and efficiency will have direct influence. Therefore, the design of transmission quality has been the focus petition in the automotive industry. This paper studies the two shafts type design six manual shift transmission,By Rachel G52010 paragraph messi version wenqi TCI automobile vehicle parameters and engine parameters for the design basis, the design of manually transmission. At first, I will give a summary of the current situation and the tendency of development of the vehicle transmission, and introduce the latest development state in the field of the second, I pare the transmitting scheme of different transmission, and choose a better structure scheme.
