The invention relates to a liquid-friction clutch (1), having a primary part (2) which is mounted by means of rolling bearings and which is driven in rotation, having a drivable secondary part (5), and having means for controlling the transmission of torque from the primary part (2) to the secondary part (5), wherein the primary part (2) is formed by at least one drive disk (4) which is connected in an axially fixed and rotationally fixed manner to an input shaft (3), wherein the secondary part (5) forms a housing (6, 7) which has a working chamber (8) which is filled with a viscous fluid and in which the drive disk (4) is rotatably mounted in such a way that a torque can be transmitted by means of the fluid from the primary part (2) to the secondary part (5), and wherein the housing (6, 7) of the drivable secondary part (5) is rotatably supported by means of at least one rolling bearing (11) on the input shaft (3). To increase the service life of the liquid-friction clutch, it is proposed that the rolling bearing (11) is an at least double-row tandem angular-contact ball bearing (20; 20'; 20'; 20' '; 26, 26'; 32, 32'), wherein the tandem angular-contact ball bearing has at least one outer ring (22; 28; 34) and at least one inner ring (21; 27; 33), between which at least two bearing rows of bearing balls (23, 24; 35, 36) are guided in raceways of different diameter. |
