Abstract
A synchronizing mechanism for clutches comprises a gearshift sleeve provided with locking teeth coacting with locking teeth of a synchronizer ring and with separate coupling teeth coacting with the coupling teeth of clutch bodies. The locking teeth of the gearshift sleeve are provided with undercuts whose flanks exhibit substantially the same angle relative to a longitudinal axis of the teeth as the wedge surfaces formed on the ends of the coupling teeth of the clutch bodies. Once synchronism has been reached, these undercuts enable the unit formed by the clutch body and the synchronizer ring to be rotated relative to the gearshift sleeve so that the coupling teeth of the gearshift sleeve can be introduced without any resistance between the coupling teeth of the clutch body.
