Study of Increase in Drag Torque at High Rotational Speed of Wet Multi-plate Clutch

Fuel efficiency of vehicle can be improved by reducing the drag torque when the A/T clutch is disengaged. To increase the distance between the plates can reduce the drag torque, but the plate distance is a complicated phenomenon that depend on the relationship of the oil flow between multiple plates. Due to its complexity, there are few cases of studying the distance between plates. In this report, the authors study the fluctuation of the plate distance and drag torque, due to the pressure between the plates, and create a mathematical model of this phenomenon．
