Abstract
The invention relates to a clutch transmission and a method of operating the same. The clutch transmission has a transmission element that is accommodated in a transmission chamber, a clutch element accommodated in a clutch chamber, and a hydraulic controller comprising an oil pump. The purpose is to provide pressures and volume flows in the clutch transmission, in which, in order to cool the clutch element, the oil pump sucks in oil and pumps it into the clutch chamber. In order to reduce churning losses in the transmission chamber to prevent air from being sucked in by the oil pump, an intake chamber is operatively connected to an oil outlet of the clutch chamber in order to receive the oil that leaves the clutch chamber.
