摘 要 离合器装在发动机与变速器之间,汽车从启动到行驶的整个过程中,常常需要使用离合器。它的作用是使发动机与变速器之间能逐渐接合,从而保证汽车平稳起步;临时切断发动机与变速器之间的联系,以便于换档和减少换档时的冲击;当汽车紧急制动时能起分离作用,防止变速器等传动系统过载,起到一定的保护作用。所设计的离合器是膜片弹簧离合器,此设计说明书详细的说明了轻型汽车膜片弹簧离合器的结构形式,参数选择以及计算过程,根据离合器系统的设计步骤和要求,对摩擦片外径的确定,离合器后备系数的确定,单位压力的确定,以及从动盘设计包括从动片设计和从动盘毂设计,主动部分的设计,包括压盘、离合器盖设计、弹性传动片设计,其中离合器盖的设计只是简单的设计,操纵机构的设计是大体上计算出踏板的行程、踏板力,是否符合人体工程学要求。关键词:离合器;设计;膜片弹簧;从动盘;压盘;摩擦片 ABSTRACTThe coupling installs between the engine and the transmission gearbox, the automobile from the start to the travel entire process, needs to use the coupling frequently. Its function is causes between the engine and the transmission gearbox can join gradually, thus guaranteed that the automobile starts steadily; Shuts off between the engine and transmission gearbox's relation temporarily, is advantageous shifts gears and reduces shifts gears the time impact; When automobile emergency brake can play the separation role, prevents transmission systems and so on transmission gearbox to overload, plays certain protective function.The clutch designed is diaphragm spring clutch, the design manual detailed the process of the diaphragm spring clutch designing of light vehicle structure, including parameter selection and calculation process, the determination of friction plate diameter, back-up clutch coefficient determination unit to determine the pressure, as well as the follower plate follower piece design includes the design and the design of the driven wheel disc, part o...
