1、Chapter8CLUTCH背景知识位置：离合器位于发动机和变速箱之间的飞轮壳内，用螺钉将离合器总成固定在飞轮的后平面上，离合器的输出轴就是变速箱的输入轴。在汽车行驶过程中，驾驶员可根据需要踩下或松开离合器踏板，使发动机与变速箱暂时分离和逐渐接合，以切断或传递发动机向变速器输入的动力。要求：接合平稳，分离迅速而彻底；调节和修理方便；外廓尺寸小；质量小；耐磨性好和有足够的散热能力；操作方便省力。种类：常用的分为牙嵌式与摩擦式两类。Chapter8CLUTCHTheengineproducesthepowertodrivethevehicle.Thedrivelineor

4、echanism.译文：离合器包括飞轮，离合器盖，压盘，弹簧，压盘盖和必要的离合器操纵机构；离合器事发动机和传动装置之间的一种旋转机构。它通过各部件的摩擦起作用。这就是为什么将离合器称之为摩擦机制。Chapter8CLUTCHAfterengagement,theclutchmustcontinuetotransmitallenginetorquetotransmissiondependingonthefrictionwithoutslippage.Theclutchisalsousedtodisengagetheenginefromthedrivetrainwhen

5、everthegearsinthetransmissionarebeingshiftedfromgearratiotoanother.译文：安装后，离合器通过摩擦不打滑将发动机的全部扭矩传递给变速器。当换挡时离合器也被用于切断传动系与发动机之间的动力。Chapter8CLUTCHTostarttheengineorshiftthegears,thedriverhastodepresstheclutchpedalwiththepurposeofdisengagementthetransmissionfromtheengine.Atthattime,thedrivenme
