Patent ID: 7461732

Claim:
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 ).
