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.
