1、 i 盘形摩擦离合器设计 摘摘 要要 离合器是汽车的重要部件。 本文针对 CA6102 发动机设计了盘形离合器,选用膜片弹 簧离合器方案,该方案优于其它方案，具有轴向尺寸小、零件数量少、主要零件形式简 单、批量生产时成本低等优点。本文确定了离合器的主要参数，总体设计了膜片弹簧离 合器的结构，具体设计了包含扭转减振器的从动盘总成、从动盘毂、膜片弹簧、压盘、 离合器盖等主要部件及主要零件， 对主要零件进行了强度校核计算， 并对其结构工艺性 进行了分析讨论。具体设计好的离合器的工作原理为：当用力推动分离轴承时，膜片弹 簧的碟簧部分变形，失去对压盘的压力，使得从动盘和飞轮之间分开，从而达到分离的 目的

2、；而当撤销对分离轴承的力时，膜片恢复到原来的变形，使得从动盘和飞轮重新结 合。 关键词: 离合器； 膜片弹簧； 扭转减振器； 摩擦片 ii Design Of Disk Friction Clutch Abstract Clutch is an important part of an automobile. In this dissertation, a disc clutch is designed for the CA6102 engine. In this disc clutch, a film spring is used because in this way the clutch

3、 is smaller in axial direction, contains less parts, and all parts own easier structures, and the cost is lower in large scale manufacturing. In this dissertation, main parameters of the clutch are determined. Whole structure of the clutch is designed Main components and parts are designed in detail

4、s, such as driven plate which includes torsional vibration damper, driven plate wheel, film spring, pressure plate, clutch shell, etcStrength of main parts is calculated, and the structures of main parts are analyzed and discussedThe working principle of the clutch is that when the bearing is pushed, film spring deforms in its circumference and the pressure on the pressure plate is lost, then the driven plate is disconnected from the flywheel; when the force imposed on the bearing is remov
