DUAL PUMP SYSTEM FOR AUTOMATIC TRANSMISSION AUGMENTATION, EXTENDED STOP AND START, AND SAILING |
| 摘要 |
A dual pump system for a motor vehicle transmission includes a first pump connected to and co-rotated with a pump shaft rotated during operation of a motor vehicle engine. A second pump is connected to a motor shaft of an electric motor. A one-way roller clutch is connected to the second pump and to the pump shaft. The one-way roller clutch is configured to allow the faster rotated one of the pump shaft or the motor shaft to drive the second pump. The pump shaft and the motor shaft can be co-axially aligned or positioned off-axis with respect to each other. |
