A transfer case includes primary and secondary output shafts, along with a secondary torque transfer mechanism and a locking mechanism, which are configured to selectively couple the primary and secondary output shafts. The secondary torque transfer mechanism comprises a sprocket coupled to the secondary output shaft, and a plate clutch coupled to the sprocket to selectively form a friction coupling with the primary output shaft. The locking mechanism selectively couples the primary output shaft to the sprocket, and includes a locking sleeve and an actuator that moves the locking sleeve between a first position and a second position. In the first position, the locking sleeve forms a first splined connection with the primary output shaft and forms a second splined connection with the sprocket. In the second position, the locking sleeve forms the first splined connection with the primary output shaft and forms a second splined connection with the sprocket.

A drive plate of an electromagnetic-fan clutch comprises: a body of the drive plate provided with magnetic-insulation air holes, connection ribs, and magnetic conductive layers. The magnetic-insulation air holes and the magnetic conductive layers are arranged alternatively along a radial direction of the body of the drive plate. A friction-increasing groove is opened on the magnetic conductive layer. The thickness of the magnetic insulation air holes and the thickness of the connection ribs are less than the thickness of the magnetic conductive layers. Six connection ribs are distributed uniformly between the magnetic conductive layers, and the connection ribs at two sides of the magnetic conductive layer are distributed along the radial direction of the body of the drive plate at an interval of 30 degrees. A drive plate through hole is opened in the body of the drive plate, and accommodation walls are disposed on the magnetic conductive layers.

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.
