Abstract
The invention relates to a synchronizing unit wherein the resilient member interposed between the coupling ring and the synchromesh rings consists of a split cylindrical expansible sleeve fitted in a pre-stressed state in the central portion of the coupling ring, said sleeve having outflaring ends adjacent to each inner surface of the synchromesh rings, respectively, said synchromesh rings being in a manner known per se rigidly interconnected. The central portion of said sleeve comprises a groove having inclined marginal portions adapted to co-act with said coupling member, whereby in the neutral position of said coupling ring the friction cones of the synchronizer are not in mutual contact. This synchronizing unit is particularly suitable for change-speed mechanisms of motor vehicles.
