摘 要 离合器是汽车传动系中的重要部件主要功用是切断和实现发动机对传动系的动力传递保证汽车平稳起步保证传动系统换挡时工作平顺以及限制传动系统所承受的最大转矩防止传动系统过载有效的降低传动系统中的振动和噪声膜片弹簧离合器是近年来在轿车和轻型车上广泛采用的一种离合器它的转矩容量大而且较稳定操作轻便平衡性好也能大量生产对于它的研究已经变得越来越重要 离合器在机械传动系统中是作为一个独立的总成而存在的它是汽车传动系统中直接与发动机相连的总成目前各种汽车广泛采用的摩擦离合器是一种依靠主从动部分之间的摩擦来传递动力且能分离的装置它主要包括主动部分从动部分压紧机构和操纵机构等四部分 此设计说明书详细的说明了带摩擦片厚度报警器的轻型汽车拉式膜片弹簧离合器的结构形式参数选择以及计算过程根据拉式膜片弹簧离合器工作原理和使用要求采用传统化设计方法把离合器分为主动部分从动部分操纵机构通过对各个部分设计方案的原理阐释和优缺点的比较确定了相关部分的基本结构及其零部件的制造材料根据车辆使用条件和车辆参数按照离合器系统的设计步骤和要求主要进行了以下工作选择相关设计参数主要为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并进行了总成设计主要为压盘的设计以及从动盘设计从动盘毂的设计和膜片弹簧的设计等 关键字离合器膜片弹簧从动盘压盘摩擦片 Abstract The clutch is an important component of the car transmission and main function is to cut and realize engine power transmission systemensure the smooth startcar transmission system shift work smoothly and limit when the imum transmission system to prevent transmission torqueoverloadReducing effectively the transmission of the vibration and noiseDiaphragm spring clutch is in recent years in cars and light bus widely adopted a clutchits large capacity of torque and stabilityconvenient operationsymmetricalalso can producefor it has become more and more important The clutch in mechanical transmission is as an independent assembly and existit is the car transmission directly connected with the engine of the assemblyAt presentall kinds of automotive friction clutch is widely used on a moving part of the friction between the subordinate to transfer power and can separate devicesIt mainly includes active parta followercompaction institutionsand manipulate agencies four parts This design specification detailed descriptions of the diaphragm spring clutch light auto structure formand calculate the parameter selection process with the annunciator of the friction disk thicknessAccording to pull the diaphragm spring clutch working principle and use by systematic design methodthe clutch is divided into active partand control mechanismsdriven partBased on the principle of each part
