Abstract: A synchronizing device of a transmission is provided with a cylindrical synchronizer body having an external toothing. A shifting sleeve includes, but is not limited to an internal toothing. The internal toothing axially displaceably meshes with the external tooting of the synchronizer body. A synchronizing ring includes, but is not limited to a locking gear rim. In clearances distributed on the circumference of the synchronizer body, pre-synchronizing elements are arranged. The pre-synchronizing elements are in spring-elastic engagement with the shifting sleeve and are arrested by the shifting sleeve in a middle position. A face end of the locking gear rim includes, but is not limited to outward bulges in direction of the pre-synchronizing elements subject to the setting of spacing between synchronizing ring and pre-synchronizing elements.

Abstract: A clutch sleeve is provided for a shift clutch having a synchronizing device, which includes, but is not limited to a clutch body, which is connected in a rotationally-fixed manner to a gear wheel mounted so it is rotatable on a shaft and has coupling teeth and a friction cone as well as a synchronizing ring having a counter cone and blocking teeth, and which has shift teeth, the clutch sleeve having shift teeth, which are designed in such a manner that a first group of the shift teeth cooperates with the blocking teeth until a synchronized speed is reached and a second group of the shift teeth engages in the coupling teeth after the synchronized speed is reached.
