| 摘要 |
The invention relates to a fluid friction clutch, for example for vehicle applications, comprising a rotationally driven primary part (1) fitted with rolling bearings, a drivable secondary part (2), and means for controlling the torque transmission from the primary part (1) to the secondary part (2), wherein the primary part (1) is formed by at least one driving disk (1b), which is connected to an input shaft (1a) in an axially and rotationally fixed manner, wherein the secondary part (2) forms a housing (2a, 2b), which comprises a working chamber (3) filled with a viscous fluid, the driving disk (1b) being rotatably disposed in the chamber such that by means of the fluid torque can be transmitted from the primary part (1) to the secondary part (2), and wherein the housing (2a, 2b) of the drivable secondary part (2) is rotatably supported on the input shaft (1a) by means of at least one rolling bearing. Increased bearing service life is achieved according to the invention in that the rolling bodies (16) of the at least one rolling bearing (6', 14') of the secondary part (2) are configured as ball rollers having two side surfaces (17a, 17b) each, which are symmetrically flattened from a basic ball shape and disposed parallel to each other. |
