The frictional behavior of wet clutches in vehicle drivetrains is critical for their overall behavior.During the development of new wet clutch systems there is a need to know this friction behavior.The transferred torque is normally investigated in test rigs where the friction in a sliding interface between a friction disc and separator disc is investigated.These test rigs can be designed differently,depending on the working conditions of the investigated clutch.However,it is possible today to simulate the clutch behavior and not limit ourselves to only using measurements from test rigs for the design of the wet clutch.The torque transferred by the clutch during engagement can be roughly divided into full film torque and boundary lubrication torque.The full film regime is possible to simulate quite well,whereas the friction in the boundary regime is much more difficult to simulate due to its strong additive dependency.To obtain a good prediction of the total engagement,friction measurements in the boundary lubrication regime are still needed.These measurements should be easy to perform and fast tests are preferable.Friction coefficients for the whole range of sliding speed,interface temperature and nominal surface pressure should be measured.To use these measurements in simulations and get a better understanding of the friction behavior,it is also preferable to conduct these measurements on a small test sample,for which the temperature and sliding speed can be regarded as constant.
Here,the friction of a small sample of a wet clutch friction disc is investigated in a pin on disc test and the temperature is measured in the sample during the tests.Measurements are compared with measurements from a test rig for whole friction discs.A good correspondence between the frictional behaviors of the different measurement methods is achieved.

哎,非专业,太累了.自己都没看懂.给你点参考吧.
湿式离合器其摩擦力的行为对车辆动力传动系统的整体行为是至关重要的.在新的湿式离合器开发中,需要知道这个摩擦力的行为.传动扭矩一般通过测试平台进行研究,在平台中,摩擦盘和分离盘之间滑动摩擦面的摩擦力被研究.测试平台根据被研究的离合器工作条件不同而分别设计.今天,仿真离合器行为是可能的,并且不限于仅仅为了设计湿式离合器而在测试平台进行测量.离合器结合期间扭矩传输大致可被分为膜片扭矩和边界润滑扭矩.膜片扭矩可以被很好地仿真,但是边界系统的仿真则困难得多,因为它有很强的归属.为了获得一个良好的总的结合数据,边界润滑系统摩擦力测试仍然是需要的.这种测试方法应该易于施行,能快速测试更好.整个滑动速度范围内的摩擦系数、表面温度和标称表面压力应该被测试.使用仿真测试能更好地理解摩擦力的行为,也有助于指导在小型样品试验中的测试.在小样品试验中,温度和滑动速度可以认为是常数.
湿式离合器摩擦盘小样品的摩擦力用针盘测试进行研究,期间,温度被测量.测量结果与使用完整摩擦盘测量进行比较.在不同测试模式中,摩擦力行为是一致的.
