摘 要：汽车变速器作为汽车动力传递的重要部分。是用来改变发动机传到驱动

Abstract: Automobile transmission is an important part of automobile power transmission. It is used to change the torque and speed transmitted by the engine to the drive shaft. Therefore, the economy, power, and driving comfort of a car depends not only on the engine, but also largely on the transmission and the matching with the transmission. <br>The transmission is composed of a variable speed transmission mechanism and a steering mechanism. It is used to change the torque and speed transmitted by the engine to the driving wheels. The purpose is to enable the car to obtain different traction and speed under various driving conditions such as starting, climbing, turning, accelerating, etc. Work within working conditions. <br>This topic examines and masters the working principle of the transmission through the design of the LaVida manual five-speed transmission. At the same time, it can check the calculation and verification of transmission gears and shafts. Finally, the design of the transmission is reached. <br>Keywords: transmission, design, gear, check, calculation

Abstract: The automobile transmission as an important part of the power transmission of the car. Is used to change the torque and speed of the engine to the drive shaft. Therefore, the economy, power, driving comfort of the car depends not only on the engine, but also on the transmission, and the match with the transmission.<br>The transmission consists of a variable speed transmission mechanism and a control mechanism. It is used to change the torque and speed of the engine to the drive wheel, in order to get the car different traction and speed under various driving conditions such as starting in place, climbing, turning, acceleration and so on, so that the engine can operate within the most favorable operating conditions.<br>This topic checks and grasps the working principle of the transmission by designing the five-speed transmission manually. At the same time can verify the transmission gear, shaft calculation and verification. The final reach edifais for the transmission.<br>Keywords: transmission, design, gear, proofing, calculation

It is used to change the torque and speed transmitted by the engine to the driving wheel, so as to make the vehicle obtain different traction and speed under various driving conditions, such as starting in place, climbing, turning, accelerating, etc., and make the engine work in the most favorable working condition range.<br>In this paper, through the design of Langyi manual five speed transmission, to check and master the working principle of the transmission. At the same time, it can check the calculation and check of transmission gear and shaft. Finally achieve the design of transmission.<br>Key words: transmission, design, gear, check, calculation<br>
