| 摘要 |
The invention relates to a positive clutch comprising coaxial, essentially rotationally symmetrical elements for transmitting torques using spur toothing (7', 7''), for example serrated toothing, in which one of the two elements situated axially opposite one another at the pitch plane of the toothing is divided along a pitch circle (R) in the region at the pitch plane of the toothing into a sleeve (2) and a ring (4), the other, undivided element (6) extending both within and outside the pitch circle (R), as seen in the radial direction, and at least one of these three elements (2, 4, 6) being displaceable away from the pitch plane of the toothing in the axial direction. According to the invention, the sleeve (2) and the ring (4) are arranged in such a way that they can be rotated relative to one another when the clutch is disengaged. <IMAGE>
