Title:
クラッチユニット内のオイル温度の計算による確定方法
Document Type and Number:
Japanese Patent JP2011522192
Kind Code:
A
Abstract:
A clutch unit (47) comprises a wet friction clutch for controllable transmission of a torque from an input element (41) to an output element (45), housing that contains the friction clutch and oil for cooling the friction clutch, and an actuator (51) for actuating the friction clutch. The actuator is attached to the housing in a thermally conductive way and has a temperature sensor (108) for sensing a temperature of the actuator. In order to computationally determine the oil temperature (TÖl) in the clutch unit (47), a thermal input power to the clutch unit is determined as a function of at least a speed of the input element and/or of the output element. The difference between the thermal input power and the thermal output power is determined, and the oil temperature is determined as a function of the difference that was determined.
