摘要：A dual drive pump system for rear wheel or front wheel drive automatictransmission in a motor vehicle includes a dual drive pump disposed off-axis of thetransmission input shaft axis and driven by a gear train driven by a hub. The dual drivepump is also driven by a gear train driven by an auxiliary motor. Torque multiplication
through the gear train allows the dual drive pump to have a smaller displacement whilestill providing the hydraulic pressure needs of the transmission. The dual drive pump maybe driven by either an engine or the auxiliary motor depending on the operatingconditions of the motor vehicle.
