Abstract
A clutch assembly incorporated into a power transfer assembly (72) of a motor vehicle is presented. The clutch assembly includes a power-operated clutch actuator (306) for moving a clutch sleeve (354) axially between released and engaged positions between two rotatory members. In the released position, relative rotation between two rotary members is prevented. Whereas in the engaged position, relative rotation is permitted. The power-operated clutch actuator (306) further includes an electromagnetic solenoid with an output member having an extended condition and a retracted condition urging the clutch sleeve (354) between positions. A shift isolation linkage mechanism (304) interconnects the output member of the solenoid to the clutch sleeve (354) and permits movement of the output member to its retracted position while a blocked tooth condition inhibits movement of the clutch sleeve (354) to its engaged position. Once the blocked tooth condition is removed, the isolation linkage mechanism (304) forces the clutch sleeve (354) to its engaged position.
