A liquid-cooled friction clutch contains at least one lamella, which is connected rotationally fixed to a driveshaft, at least one lamella, which is connected rotationally fixed to an output shaft, these lamellae being able to be pressed mutually against one another and being positioned inside a clutch housing connected rotationally fixed to the driveshaft, and a coolant liquid return line, which leads from an area radially outside the lamellae to an area radially inside the lamellae and returns coolant liquid after its radial flow along the lamellae from the radial external area into the radial internal area, an end area of the return line being implemented as a scoop tube having an intake opening which is immersed radially outside the lamellae in a coolant liquid ring rotating together with the clutch housing and returns the coolant liquid into the area radially inside the lamellae without flowing through a pump driven by external force.
A method for cooling a liquid-cooled friction clutch, wherein the clutch includes a housing (38) in which both in which method coolant liquid is supplied radially inside lamellae (18, 20, 26, 28), which transmit torque and may be frictionally engaged, and is removed radially outside the lamellae, and is resupplied at least partially radially inside the lamellae after flowing through a return flow path (36, 40, 41), wherein at least a part of the coolant liquid removed radially outside the lamellae (18, 20, 26, 28) is resupplied by a scoop tube (34) radially inside the lamellae, wherein an immersion depth of the scoop tube (34) in the coolant liquid is regulated by a force equilibrium between a force which is exerted by a coolant liquid ring (30) rotating outside the lamellae on a scoop tube (34) immersed in the coolant liquid ring, and a force which pre-tensions the scoop tube to increase its immersion depth, and wherein the scoop tube (34) is at least partially displaced within a housing (38).
