Abstract

An equalizing unit of a drive train of a motor vehicle includes a clutch device to be oiled in driving mode. In order to stop drag torques which act on the clutch device from the outside, and result in increased dissipation when said clutch device is not required due to an operating state, measures are provided which promote the dry running of the clutch device. The measures include the spatial-functional separation of the oil delivery device from the clutch device and the provision of a braking or decoupling device by which the oil delivery device can be deactivated if there is no oil requirement.
