BALANCED BINARY PUMP FOR CVT TRANSMISSION |
| 摘要 |
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. |
