Abstract:
A clutch (1) comprising:a sliding sleeve (17) being non-rotatably connectable with a transmission component (3) via at least one guide (11) and the sliding sleeve (17) having selector teeth (19);first and second synchronizing rings (28, 29) each having locking teeth (30, 31) located for engagement with the selector teeth (19) of the sliding sleeve (17), the first and the second synchronizing rings (28, 29) being rotatable relative to the sliding sleeve (17) only over a limited angle of rotation, the first synchronizing ring (28) having a friction surface (24) located on a side thereof remote from the sliding sleeve (17), and the second synchronizing ring (29) having a friction surface ( 25) located on a side thereof remote from the sliding sleeve (17);first and second clutch bodies (20, 21) each having coupling teeth (22, 23) located for engagement with the selector teeth (19) of the sliding sleeve (17), the first clutch body (20) having a countercone friction surface (26) for interacting the friction surface (24) of the first synchronizer ring (28) and the second clutch body (21) having a countercone friction surface (27) for interacting the friction surface (25) of the second synchronizer ring (29) whereby, in an engaged state of the clutch, the sliding sleeve (17) is positively connected, via the selector teeth (19) and the coupling teeth (22 or 23), with one of the first and the second clutch bodies (20, 21);wherein the first and the second synchronizing rings (28, 29) are coupled to rotate with one another so that the locking teeth (30) of the first synchronizing ring (28) and the locking teeth (31) of the second synchronizing ring (29) substantially always rotate with one another regardless of whether the sliding sleeve (17) is positively connected with the first clutch body (20) or the second clutch body (21).
