Motor driven transfer case with modular actuation

摘要

A transfer case (30) and a method of assembly in an all-wheel drive vehicle can include a range shifting assembly (60) for shifting between a low-range and high-range drive mode, a normally disengaged clutch assembly (80) for transferring drive torque to a first and second driveline, a clutch actuator (88), and an actuating gear (48). The clutch actuator (88) can be moveable between an expanded position and a contracted position and engageable with the clutch assembly (80) for engaging the clutch assembly (80) when in the expanded position. The actuating gear (48) can be reversibly rotatable through a predetermined angular arc of movement for operating the clutch actuator (88) between the contracted and expanded position for actuating the clutch assembly (80) and for shifting the range shifting assembly (60) between a low-range drive mode and a high-range mode when the clutch assembly (80) is in the disengaged position.
