Abstract
An electric drive provides transmission oil cooling. An oil circuit supplies the transmission with oil. A cooling circuit cools a supply device and/or an electric motor with a coolant. A heat exchanger portion is coupled on one side to the cooling circuit and on the other side to the oil circuit. The supply device is arranged in a supply housing region. The heat exchanger portion forms a wall portion of the supply housing region. An end cover closes the heat exchanger portion. The end cover has at least one functional region, wherein the functional region is designed as a counterpart cooling structure, as an oil sump region and/or as a pump interface for coupling an oil pump.
Claims11
An electric drive for a vehicle, comprising:
- at least one electric motor for generating a drive torque;
- a supply device for supplying the electric motor with electrical energy;
- a transmission for guiding the drive torque;
- an oil circuit for supplying the transmission with oil;
- a cooling circuit for cooling the supply device or the electric motor with a coolant;
- a heat exchanger portion coupled on a first side to the cooling circuit and on a second side to the oil circuit;
- a supply housing region, the supply device being arranged in the supply housing region and the heat exchanger portion forming a wall portion of the supply housing region;
- an end cover closing the heat exchanger portion;
- wherein
- the end cover has functional regions, wherein the functional regions are formed at least by a counterpart cooling structure facing the heat exchanger portion and by an oil sump region, wherein the surface of the end cover is enlarged by the counterpart cooling structure in the region of the counterpart cooling structure relative to one of the base surfaces of the end cover on which the counterpart cooling structure is formed on the end cover.
