摘要
早在1889年，法国人标致研制成功世界上第一台手动机械式4挡齿轮传动汽车变速器。自此，齿轮传动的机械变速器便成为汽车动力传动系统中不可或缺的主要总成，并以传动效率高、结构简单、易制造、易操作、易维修、经济、可靠而配置在各类汽车上。自20世纪80年代起，为满足现代客车适应节能、环保、安全、舒适、高效、可靠方面不断提高的要求，专门用于客车上的手动客车变速器便从客、货通用的变速器系列中分离出来。
The article mainly introduced the current technological features and development trend of manual gear-transmission of bus in and outside China.It is believed that development trend of manual gear-transmission would be going toward to a comprehensive function,combination of latest cutting edge technology application and easily operation.In addition,higher reliability,electronic-operated and intelligentization.
