Abstract
A transmission includes a transmission housing with an oil reservoir and a transmission housing cover to close an opening of the transmission housing. A transmission shaft receives a toothed wheel and which can be driven by way of a motor. A cooler is arranged on the outside of the transmission housing, with a fan arranged on the outside of the transmission housing feeding cooling air to the cooler. An oil delivery pump pumps oil through oil delivery lines from the oil reservoir to the cooler, with an oil return line routing oil from the cooler back to the transmission housing. A separate drive motor drives the fan and the oil delivery pump independently of the transmission shaft, with the drive motor, the fan, the cooler and the oil delivery pump being fastened to the transmission housing cover.
