The invention relates to a clutch assembly of a motor vehicle, in particular a clutch-controlled differential unit, comprising a switchable clutch apparatus that is able to transmit driving power from a drive element on the input side with regard to the clutch device to a drive element on the output side with regard to the clutch device, wherein an oil conveying apparatus is provided for the clutch oiling, which oil conveying apparatus conveys oil of an oil circuit serving the clutch device depending on the operating state. In order to ensure that the lubrication of components arranged on the output side with regard to the clutch device is ensured in operating states in which the oil conveying apparatus does not convey any oil, an oil accumulating device is provided.

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.

The invention relates to a hybrid drive unit, in which for the most optimum possible synergetic use of the combustion engine drive and electromotive drive, a multi-speed clutch- and gear assembly is provided, in which both the combustion engine drive power and also the electromotive drive power is introduced into an input member of the clutch- and gear assembly. Hereby, numerous drive variants are made possible, which allow the drive machines to cooperate with each other according to requirements. The invention additionally relates to the method by which such a drive unit is operated.
