奔驰轿车两前轮上装有制动器摩擦片过薄报警系统,它能自动检测摩擦片的磨损程度,当车轮制动器上的摩擦片磨损到极限厚度时,其上的传感器能把信号传送给电子控制器,自动使摩擦片过薄报警指示灯点亮,以提醒驾驶员要更换摩擦片。现仅以奔驰280EC型轿车为例,介绍其工作情况及故障检测方法。 Mercedes-Benz cars equipped with two brake front brake friction film too thin alarm system, which can automatically detect the degree of wear friction plate, when the wheel brake friction plate wear to a limit thickness, the sensor on its signal can be sent to the electronic controller , Automatically make the friction plate too thin alarm indicator light to remind the driver to replace the friction plate. Mercedes Benz 280EC sedan is only an example, describes its work and fault detection methods.
