<p>A power transfer unit (PTU) (101) for a motive device includes an outer housing (229, 230) and a torque transferring clutch (216, 217, 218, 222). The PTU (101) also includes a piston housing (240) located between the outer housing (229, 230) and the torque transferring clutch (216, 217, 218, 222), and a piston (211) in the piston housing (240). The piston (211) is arranged to provide actuation forces to the torque transferring clutch (216, 217, 218, 222), and to restrict reaction forces back to the piston housing (240).</p> |
