Abstract: 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.

Abstract: A flexible binary pump system for a motor vehicle transmission includes a shaft, a first vane pump mounted on the shaft and having a first rotor with a first diameter and a first width and a second vane pump mounted on the shaft and having a second rotor with a second diameter and a second width. The first vane pump provides hydraulic fluid to the transmission at a first pressure, and the second vane pump provides hydraulic fluid to the transmission at a second pressure. The first diameter, first width, second diameter, and second width are selected to optimize power consumption of the binary pump system and hydraulic fluid budget for the transmission.
