离合器是汽车传动系的一个组成部分。汽车由起步、进入正常行驶、变速、减速制动直至最后停车的整个行驶过程中,离合器都在不时地起着作用。使用中由于各部件的磨损,离合器的技术状况会逐渐变坏,摩擦力矩也相应降低,经常出现的故障有打滑、分离不彻底、发抖、踏板沉重及异响等,对离合器的工作性能、使用寿命和行车安全都将产生不利影响。准确地找出产生故障的实质原因,是保证正确修理的前提,为此,将离合器常见故障的诊断方法简述如下。 一、离合器异响诊断 在发动机怠速运转,变速器置空档,拉紧驻车制动器的情况下,若在踏下离合器踏板的过程中或将踏板踏到底出现异响,则是离合器故障。其异响原因可根据异响 Clutches are an integral part of the car driveline. Starting from the car, into the normal driving, speed, deceleration braking until the last stop of the entire journey, the clutch is from time to time to play a role. In use due to the wear and tear of the various components, the technical condition of the clutch will gradually deteriorate, the friction torque is also reduced, the frequent failures are skidding, separation is not complete, shaking, heavy pedal and abnormal sound, the clutch performance, use Life expectancy and driving safety will have a negative impact. Accurately identify the cause of the failure of the real reason is to ensure the correct repair of the premise, for the clutch common fault diagnosis method is briefly described below. First, the clutch noise diagnosis In the engine idling, transmission neutral, the parking brake, if the clutch pedal in the process or the pedal in the end there is abnormal sound, it is the clutch fault. The abnormal sound can be based on abnormal sound
