摘要

Synchronous coupling for shifting a gear in a speed change gear for motor vehicles comprises an internally toothed shift sleeve that can be shifted via a clutch body (16) with external teeth that interacts with a gear wheel. The external teeth (20, 22, 24) are provided with a roof-shaped chamfer (20a, 20b, 24a, 24b) with angled surfaces adjoining the tooth face (20d) that end in a front edge (20c, 22c, 24c). The front edges of the teeth at least on their radially outer-lying end regions are offset relative to the internal teeth of the clutch sleeve.
