Cooling lubrication system comprising a dry sump
A cooling lubrication system comprises a dry sump, an oil tank, and a pump system that operates an oil circuit in which an oil pump delivers oil from the dry sump into the oil tank, and the pump system comprises a vane cell pump and two gerotor pumps on a shaft.
1. A cooling lubrication system comprising: a dry sump, an oil tank, and a pump system that operates an oil circuit in which an oil pump delivers oil from the dry sump into the oil tank, wherein the pump system comprises a vane cell pump including vanes and two gerotor pumps on a shaft, wherein one of the two gerotor pumps is connected on the pressure outlet side to under-vane grooves in the vane cell pump to supply pressurized oil to the vanes and preload the vane cell pump.
2. A cooling lubrication system according to claim 1 , wherein the vane cell pump is of a double-flow design and comprises two independent suction points in the dry sump.
3. A cooling lubrication system according to claim 1 , wherein the double-flow vane cell pump has a common pressure outlet.
4. A cooling lubrication system according to claim 1 , wherein the gerotor pumps are connected on the pressure side to a gear supply and a cooling for an electric machine.
