  • Friction engagement device
    Patent number: 10808777
    Abstract: The friction engagement device connects the input shaft and the output shaft to transmit a driving force from a driving source from the input shaft to the output shaft. The friction engagement device includes a housing, a friction engagement portion, a piston, an oil pump, and a motor. The housing is disposed between the input shaft and the output shaft. The friction engagement portion is disposed in the housing and composed of a plurality of friction components. The piston is disposed at one side of the friction engagement portion for pressing the friction engagement portion. The oil pump is used to operate the piston. The motor is used to drive the oil pump. In the friction engagement device, abnormal wear of the friction components of the friction engagement portion is detected by monitoring a value of an operation parameter of the friction engagement device.
