北京汽车乐天版手动变速器三维设计摘　　要

汽车传动系是汽车的核心组成部分。其任务是调节变换发动机的性能，将动力有效而经济地传至驱动车轮，以满足汽车的使用要求。变速器是完成传动系任务的重要部件，也是决定整车性能的主要部件之一。变速器的设计水平对汽车的动力性、燃料经济性、换挡操纵的可靠性与轻便性、传动平稳性与效率等都有直接的影响。随着汽车工业的发展，轿车变速器的设计趋势是增大其传递功率与重量之比，并要求其具有更小的尺寸和良好的性能。本设计以现有企业正在生产的车型北汽e系列手动变速器为基础，在给定发动机输出转矩、转速及最高车速、最大爬坡度等条件下，着重对变速器齿轮的结构参数、轴的结构尺寸等进行设计计算并进行优化；且对变速器的传动方案和结构形式进行设计；同时对操纵机构和同步器的结构进行设计；从而提高汽车的整体性能。

abstract

Automotive powertrain is a core component of the car. Its mission is to transform regulate engine performance, the power transmitted effectively and economically driven wheels to meet the requirements of the car. Transmission is an important component to complete drivetrain task is one of the main components of the vehicle determines performance. Gearbox design standards for cars power, fuel economy, reliability and shifting operation portability, stability and transmission efficiency, etc. have a direct impact. With the development of the automobile industry, car transmission design trends is to increase its transmission power to weight ratio, and is required to have a smaller size and a good performance. The design of existing enterprises are producing BAIC e series manual transmission models, based on a given engine output torque, speed and maximum speed, maximum gradeability conditions, focusing on the structural parameters of the transmission gear shaft structure size and other design calculations and optimizations; and structure of the program and drive transmission design; while the steering mechanism and synchronize the structure design; thus improving the overall performance of the car.

Keywords: transmission; gear; synchronizer; design; structure
