1、摘 要离合器在机械传动系中是作为一个独立的总成而存在的,它是汽车传动系中直接与发动机相连接的总成。汽车从启动到行驶的整个过程中,经常需要使用离合器。它的作用是使发动机与变速器之间的组件接合,从而保证汽车平稳起步;暂时切断发动机与变速器之间的联系,以便于换挡和减少换挡的冲击;当汽车紧急制动时能起到分离的作用,防止变速器等传动系统过载,起到一定的保护作用。本次所设计的离合器是膜片弹簧离合器,此设计说明书以SF2310-4时风低速货车为本次设计的参照车型。说明了轻型货车膜片弹簧离合器的结构形式,参数以及计算过程,按照离合器系统的设计步骤和要求,对摩擦片外径D进行确定,离合器后备系数进行确定,单位压力
2、P0进行确定,以及从动盘设计,包括从动片设计和从动盘毂进行设计,主动部分的设计,包括压盘、离合器盖设计、弹性从动片设计,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 clutch is present as a separate assembly in the mechanical drive train, which is the assembly directly connected to the engine in the driveline. Car f
3、rom the start to the entire process of driving, often need to use the clutch. Its role is to make the engine and the transmission between the components can be connected to ensure a smooth start of the car; temporarily cut off the connection between the engine and the transmission in order to shift
4、and reduce the impact of the shift; when the car can play an emergency brake The role of separation, to prevent transmission and other transmission system overload, play a protective role.This design of the clutch is a diaphragm spring clutch, this design to SF2310-4 when the wind low-speed truck fo
5、r the design of the reference model. The structure, parameters and calculation process of the light truck diaphragm spring clutch are described. The outer diameter D of the friction plate is determined according to the design steps and requirements of the clutch system. The clutch backup coefficient
6、 is determined and the unit pressure P0 is determined. The design of the drive plate, including the design of the driven plate and the driven plate hub, the design of the active part, including the pressure plate, the clutch cover design, the elastic follower design, in which the design of the clutc
7、h cover is simply designed, the design of the steering mechanism Is to calculate the pedal of the trip, pedal force is ergonomic requirements.Key words: Clutch; Design; Diaphragm spring; Driven plate; Pressure plate; Friction plate目 录摘 要IIAbstractIII1 绪 论41.1 时风低速货车离合器的工作原理和作用41.2 时风低速货车离合器的设计要求41.3
