Abstract: A vehicle trailer for a towing vehicle has a first wheel and at least one second wheel. At least one electric auxiliary drive system is coupled to the first wheel and second wheels for exerting a first torque on the first wheel and a second torque on the second wheel(s). The auxiliary drive system is adapted as an electrical auxiliary drive system capable of recuperation with an auxiliary energy storage device. A force measuring device can measure a longitudinal force signal as the longitudinal force exerted by the towing vehicle on the vehicle trailer by means of a connection. A control unit is adapted to adjust the torque to the first and second wheels on the basis of the electric auxiliary drive system and as a function of the longitudinal force, while maintaining a minimum tractive force. The invention also relates to a vehicle train.

Abstract: A cooling oil guiding device for a clutch actuatable by an axially movable piston. The piston is radially inward of the clutch, and separates a pressure space and a compensation space. The compensation space is delimited by an axially stationary compensation space cover and a seal cover coupled to the piston. The compensation space cover and the seal cover axially overlap radially outwardly and are axially movable relative to one another via a sealing element. An overflow opening connects the compensation space to an oil channel in the seal cover between the seal cover and the piston, the oil channel opens radially outward. A control edge is provided at a component part axially immovable relative to the piston, by which an oil flow exiting from the oil channel is guided through the clutch when the clutch is closed and is guided past the clutch when the clutch is open.
