ABSTRACT:
An electromagnetically controlled bi-directional one-way clutch apparatus which permits relative overrun or differentiation between a front torque transmitting shaft and a rear torque transmitting shaft up to a predetermined level and, if the amount of relative overrun or differentiation between the front torque transmitting shaft and the rear torque transmitting shaft exceeds this predetermined level, locks the front torque transmitting shaft and the rear torque transmitting shaft together such that the front torque transmitting shaft and the rear torque transmitting shaft rotate at substantially the same rotational speed. This electromagnetically controlled bi-directional one-way clutch apparatus is particularly useful for use in an "on demand" four-wheel drive system for a motor vehicle having an engine and a front wheel drive transaxle assembly where the electromagnetically controlled bi-directional one-way clutch apparatus acts as a torque transmitting device which allows relative overrun or differentiation between the front wheels and the rear wheels of the motor vehicle up to a predetermined level and, if the amount of relative overrun or differentiation between the front wheels and the rear wheels of the motor vehicle exceeds this predetermined level, locks the front wheels and the rear wheels of the motor vehicle together such that the front wheels and the rear wheels of the motor vehicle rotates at substantially the same rotational speed.
