TRANSMISSION PUMP DRIVE

摘要

A pump drive (48) for a vehicle transmission pump. A transmission input torque member (24) is operable to carry prime mover torque. A source of pump torque includes a pump input torque member (62) circumscribing the transmission input torque member to apply torque to the transmission pump (42). An overrunning clutch (84) is interposed between the pump input torque member and the transmission input torque member to carry the prime mover torque from the transmission input torque member to the pump torque output member.
