I 乘用车关键部分设计 摘 要本设计的任务是为汽车设计手动变速器。 该设计采用中间轴传动，该传动具有两个突出优点:一是速度传动效率，磨损和噪声极小； 其次，在较小的齿轮中心仍能获得较大传动比的情况下。 根据汽车的形状， 轴距，轴距，最小地面净空，最小转弯半径，车辆重量，满载重量和最大速度，结合他们自己对发动机型号的选择，可以获得最大发动机功率，位移和其他重要参数。 结合一些汽车的基本参数，选择合适的主减速比。根据上述参数，结合汽车设计，汽车理论，机械设计等相关知识，计算相关传动参数，论证设计的合理性。它的功能是:(1)改变传动比,扩大驱动旋转扭矩和转速,以适应不断变化的行驶条件,如起步、加速、山,同时使发动机在有利条件下工作;(2)在电动机旋转方向不变的前提下,可使汽车向后;(3)使用的差距,中断动力传递,以使发动机启动,发动机空转,促进转变或功率输出。传输有五个前进档和反向,并通过锁环同步转变。关键词： 变速器；锁环式同步器；传动比；校核 AbstractThe task of this design is to design manual transmission for automobile. The design adopts II 乘用车关键部分设计the intermediate shaft transmission, which has two outstanding advantages: the first is the speed transmission efficiency, the wear and noise are very small; the second is that the smaller the gear center can still obtain the larger transmission ratio.According to the shape, wheelbase, wheelbase, minimum ground clearance, minimum turning radius, vehicle weight, full load weight and maximum speed of the car, combined with their own choice of engine model, they can obtain the maximum engine power, displacement and other important parameters. Combined with the basic parameters of some vehicles, the appropriate final drive ratio is selected. According to the above parameters, combined with automobile design, automobile theory, mechanical design and other related knowledge, calculate the relevant transmission parameters, and demonstrate the rationality of the design.Its functions are: (1) changi...
