三轴式五档机械变速器Three axis of mechanical transmission of five files Students: LiHanguang (professional: automobile service engineering) Teacher: He Dongwei (unit: tongji university) 【 abstract 】 now, whenever people watch F1 competition, there would be that kind of extreme feeling tracks. At the moment, everyone seems to talk about is what most of the engine performance and drivers in technology. Also, don't forget when in driving read speed feel or in purchase attention to engine performance, this seems to be the horizontal quantity of a standard car quality quality. Indeed, with a single "healthy heart" is very important, because it is the power of the creator. But, control the machine speed, but it behind the transmission. From now on the market which different types of allocation of mainly divided into: see, transmission manual transmission (MT), automatic transmission (AT), manual/automatic transmission (AMT), variator (CVT). 【 keywords 】 input shaft; The output axis; Transmission; Oart... 目录1 前 言 .......................................................................... 12 变速器的基本设计方案.......................................................... 22.1 变速器设计的基本要求:......................................................................................................... 2 2 变速器主要参数的选择............................................................................................................... 3 3 变速器各档齿轮的计算设计...................................................... 53.1 模数 ........................................................................................................................................... 5 3.2 压力角 ................................................................................................................................
