Test Method Research on Friction Disc of Wet Clutch in Automatic Transmission

自动变速器湿式离合器摩擦片的测试装置可以通过变更滑动速度、转动惯量、法向作用力和润滑油量,测量得包括法向力、制动力矩、滑动速度和随时间变化的温度等数据。这些输入参数与所得到的输出数据与工程机械自动变速器中的参数与数据极为相似。

The test apparatus to friction disc of wet clutch in automatic transmission can change some test parameters, such as sliding velocity, turning inertia, normal applied force and lubrication volume. The measured output data include normal force, brake torque, sliding velocity and temperature variation with time. The input parameters and output characteristics obtained from this apparatus are similar to those in the automatic transmissions used in a car
