ABSTRACT:
There is disclosed a fluid clutch device for controlling transmission of motive power of a vehicular engine to accessory equipment such as an oil pump for a power steering mechanism or an air compressor for an air conditioner. The clutch device includes first and second members arranged for relative rotation about a common axis. The first member is operated by the vehicular engine while the second member is constructed to operate the accessory equipment. The first and second members are accommodated in a hermetically sealed clutch casing which is filled with an electroviscous fluid. A source of high voltage potential is provided for applying a voltage to the electroviscous fluid, and various units for generating information regarding driving of the accessory equipment are also used. A clutch control unit is electrically connected to the source of high voltage potential and the information-generating units, and regulates the voltage applied to the electroviscous fluid based on the information generated from the information-generating units to vary a driving power for operating the accessory equipment.
