1、 五菱宏光手动变速器设计 系部名称： 汽车工程系 专业班级： 学生姓名： 指导教师： 职 称： 二一一年六月 摘摘 要要 变速器用来改变发动机传到驱动轮上的转矩和转速，目的是在原地起步，爬坡， 转弯，加速等各种行驶工况下，使汽车获得不同的牵引力和速度，同时使发动机在最 有利工况范围内工作。变速器设有空挡和倒挡。需要时变速器还有动力输出功能。 因为变速箱在低档工作时作用有较大的力，所以一般变速箱的低档都布置靠近轴 的后支承处，然后按照从低档到高档顺序布置各档位齿轮。这样做既能使轴有足够大 的刚性，又能保证装配容易。变速箱整体结构刚性与轴和壳体的结构有关系。一般通 过控制轴的长度即控制档数，来保证

2、变速箱有足够的刚性。 本文设计研究了三轴式五挡手动变速器，对变速器的工作原理做了阐述，变速器 的各挡齿轮和轴做了详细的设计计算，并进行了强度校核，对一些标准件进行了选型。 变速器的传动方案设计并讲述了变速器中各部件材料的选择。 关键字：变速器；设计；齿轮；轴；校核 ABSTRACT Transmission to change the engine reached on the driving wheel torque and speed, is aimed at marking start, climbing, turning, accelerate various driving cond

3、itions, the car was different traction and speed Meanwhile engine in the most favorable working conditions within the scope of the work. And the trans mission in neutral gear with reverse gear. Transmission also need power output function. Gearbox because of the low-grade work at a larger role, In g

4、eneral, the low-grade gearbox layout are close to the axis after support, Following from low-grade to high-grade order of the layout of stalls gear. This will not only allow axis are large enough for a rigid, but also ensures easy assembly. Gear box overall structure and rigid axle and the shell str

5、ucture of relations. Generally through the control shaft length control over several stalls to ensure that adequate gear box rigid. This paper describes the design of three-axis five block manual tran mission, the transmission principle of work elaborated, Transmission of the gear shaft and do a det
