The axially displaceable release bearing (7, 15) of a clutch (1), especially a multiple disc clutch, comprises a releaser element (7) rotating together with the clutch (1) and a releaser element (15) stationary in relation thereto. An internal gear pump (11) delivers a current of cooling oil into the clutch (1). The internal gear pump comprises an annular, internally toothed outer gear wheel (5) and an externally toothed inner gear wheel (6) arranged therein. The outer gear wheel (5) and the inner gear wheel (6) are mounted rotatably in a housing (12, 13), mounted on the releaser element (15), of the internal gear pump (11) such that the pump moves axially with the release bearing. The outer gear wheel (5) additionally carries an external toothing (10) which meshes with an external toothing (9) of the rotating releaser element (7). In further embodiments the toothing (10) may be centrally positioned on gear wheel (5) with locating rings on either side for radial location of the wheel (5) in the housing (12, 13). Alternatively toothing (10) may be full width with locating sleeves on either side of the meshing with toothing (9). <IMAGE> |
