Abstract: An electromagnetic clutch assembly may include a first clutch plate, a second clutch plate, and a synchronizer. The second clutch plate may define an aperture. A portion of the synchronizer may be configured to extend through the aperture. In the absence of a magnetic field, the first clutch plate and the first surface of the second clutch plate may define an air gap and the portion of the synchronizer may extend into the air gap. In response to a first magnetic field, the portion of the synchronizer may contact the first clutch plate. In response to a second magnetic field, the portion of the synchronizer may translate in the aperture toward the second clutch plate and the first clutch plate and the second clutch plate may close the air gap.

Abstract: 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.

Abstract: An electromagnet for brakes and clutches having outer and inner poles and an electrical coil for creating a magnetic field between these poles is provided having a circumferential gap in the forward portion of the outer pole. The gap reduces the flux density over the forward portion of the magnet face while increasing the flux density over the rearward portion. The variable flux density over the magnet face thus establishes an unbalance of forces attracting the magnet toward the armature plate causing the magnet to engage the armature plate heel first thereby eliminating "squeal" caused by magnet gouging and two plane wear of the magnet's friction face.
