摘要： A rotational coupling includes a coupling disc configured to be disposed about a shaft having a rotational axis. An electromagnet assembly on one side of the coupling disc includes a housing and a conductor within the housing. An armature is disposed on an opposite side of the coupling disc opposite the conductor and the coupling disc, electromagnet assembly and armature form an electromagnetic circuit when current is supplied to the conductor to urge the armature towards engagement with the coupling disc. An anti-rotation mechanism for the electromagnet assembly includes one or more coupling permanent magnets and one or more fixed permanent magnets configured to be mounted to an outer surface of the housing of the electromagnet assembly and a fixed support structure, respectively. The coupling and fixed permanent magnets are arranged to inhibit movement of the coupling permanent magnets and electromagnet assembly in either rotational direction about the rotational axis.

摘要： A fail-safe friction clutch assembly for a vehicle accessory, particularly to drive a vehicle cooling pump, and more particularly as part of a dual mode drive for a cooling pump, together with an electric motor. The friction clutch assembly includes a friction plate member connected to a central rotatable shaft member used for operating the vehicle accessory. A pair of friction lining members are positioned on opposite sides of the friction plate member. An armature member is spring biased to axially force the friction plate member and friction lining member against a housing or cover which is rotating at input speed. A solenoid assembly is used to overcome the spring bias and pull the armature and friction plate member away from the housing.
