Abstract
A locking synchronizer for a motor vehicle gear transmission having a shift sleeve with an inner cone that is displaceable lengthwise on a guide sleeve, a synchronizing ring with an outer cone and an annular projection with teeth mounted on the loose gear to be engaged. During synchronization and shifting, claws mounted internally on the synchronizing ring engage tooth gaps in the annular projection. The shifting motion is opposed by a snap ring which is guided radially movably in an annular groove of the annular projection and is tensioned by the conical inner circumferential surfaces of the claws.
