A power takeoff unit is comprised of: a casing dividable into a first part and a second part; an inner shaft receiving torque from an engine; an outer shaft independently rotatable and coaxial with the inner shaft; a clutch for connecting the inner shaft with the outer shaft; an actuator configured to connect the clutch; an output shaft for outputting torque; and a gear set drivingly coupling the outer shaft with the output shaft, wherein the outer shaft and the output shaft are rotatably supported by the first part, the clutch is rotatably supported by the second part, and the actuator is fixed to the second part, whereby the clutch and the actuator along with the second part are separable from the first part.

Power takeoff unit for automobile

A transmission device is comprised of a clutch disconnectably and drivingly coupling a first rotary member with a second rotary member; a motor including a rotor rotatable about an axis; an input member coupled with the rotor and rotatable about the axis, the input member including an eccentric shaft eccentric relative to the axis; a fixed member immovable about the axis; an intermediate member fitting with the eccentric shaft to make an eccentric motion and meshing with the fixed member to make a rotary motion about the eccentric shaft; an output member rotatable about the axis and fitting with and following the intermediate member; and a cam mechanism intervening between the output member and the clutch to convert a rotary motion of the output member into a motion in a direction along the axis to press the clutch.

Transmission device

A driving force transmitting device is comprised of a first rotary member, a second rotary member securely fit around the first rotary member, a third rotary member rotatably supported in the first and second rotary members for being engaged with a shaft, an anti-rotated solenoid slidably fit in a solenoid housing hollow defined by the second rotary member, and a friction clutch driven by the solenoid for transmitting torque between the first rotary member and the third rotary member.
