Abstract
A power transfer unit (PTU) for a motive device includes an outer housing and a torque transferring clutch. The PTU also includes a piston housing located between the outer housing and the torque transferring clutch, and a piston in the piston housing. The piston is arranged to provide actuation forces to the torque transferring clutch, and to restrict reaction forces back to the piston housing.
