Hydraulic Oil Pump for 9DCT
After using an electric auxiliary oil pump, the power and displacement of the mechanical oil pump can be designed based on the basic load, with the displacement reduced by about 1/3. The peak load is supplemented by the electric auxiliary oil pump, which supplies oil as needed.
In this way, the losses caused by the residual design of the mechanical oil pump can be greatly reduced. It can also maintain the energy required for the transmission to work when the engine is stopped, continue to provide a certain amount of oil pressure, and maintain or quickly enter the operating state of the transmission. The transmission can continue to supply oil to components during startup, shutdown, and coasting modes, regardless of the engine speed, It can also improve the responsiveness of clutch re engagement during engine restart.
