The invention concerns a clutch (1) comprising a sliding sleeve (17) with selector teeth (19), two synchronizing rings (28, 29) situated on either side of the sliding sleeve (17) with locking teeth (30, 31) and friction surface (24, 25) which can be turned about a limited rotation angle in relation to the sliding sleeve (17) and two clutch bodies (20, 21) with clutch teeth (22, 23) and counter friction surface (26, 27), the clutch bodies (20, 21) interacting with the synchronizing rings (28, 29) wherein the sliding sleeve (17) is constantly connected with a gear element (3) in a way torsionally resistant and when engaged is connected to one of the clutch bodies (20, 21) via the selector teeth (19) and the clutch teeth (22, 23) with positive fit. In order to make possible a limited rotation angle between the sliding sleeve (17) and the synchronizing rings (28, 29) in a specifically narrow, externally guided, sliding sleeve (17), it is proposed that the synchronizing rings (28, 29) have several cams (32, 33) distributed over the periphery which engage in grooves (44) of the externally guided sliding sleeve (17) with a clearance thus defining the limited rotation angle, some of the cams (32) of one synchronizing ring (28) extending into the area of the other synchronizing ring (29) and vice versa. |
