高级轿车的制动性能较稳定,故障甚低。为了减少车轮的拆装次数,有些高级轿车上装用能报警的车轮制动摩擦片。它能自动检测其磨损程度,当摩擦片磨损到只有一定厚度时,其上的传感器能自动使过薄报警灯亮,提示要换摩擦片。该装置由带传感器的特殊摩擦片,电子控制器和指示灯组成,在该特殊摩擦片的一定深度埋有一短接线,当摩擦片磨损到只有2.0～2.2mm极限厚度时,短线自动磨断;传感器立即把信号传至电子控制器,使红色指示灯发出告警信号。其结构示意图述后。 大多数奔驰轿车的仪表盘上有一个图标为|○|的
The limousine’s braking performance is more stable, the fault is very low. In order to reduce wheel disassembly times, some limousines are equipped with wheel brake pads that can alarm. It can automatically detect the degree of wear, when the friction plate worn to only a certain thickness, the sensor on it can automatically make the alarm light too thin, suggesting that the friction plate. The device is composed of a special friction sensor with sensors, an electronic controller and an indicator lamp. A short wiring is buried at a certain depth of the special friction plate. When the friction plate is worn to a limit thickness of only 2.0 to 2.2 mm, The sensor transmits the signal to the electronic controller immediately, so that the red indicator light sends a warning signal. The structural diagram is described below. Most Mercedes cars have an icon dashboard on the dashboard
