ABSTRACT:
A synchronization device for gear shaft mechanisms includes an outer synchronization ring which is formed as a deep-drawn plate section which is toothed on its outer perimeter to correspond to locking cogs of a clutch sleeve and a coupler. The outer synchronization ring has a conical friction surface in its middle area and locking tabs on its inner circumference in a deep-drawn bottom area thereof. The locking tabs provide a form-locked solid coupling with a synchronizer which has mating recesses which open outward radially and extend inward radially from an outer periphery of the synchronizer. A dimensionally exact and simple manufacturing of the outer synchronizing ring is provided in very few work steps enabling the synchronization device to be attractive for many uses which were previously avoided due to cost.
