  • Transmission synchronizer assembly
    Patent number: 8550226
    Abstract: A transmission synchronizer assembly is provided that alleviates noise associated with functional clearances and backlashes. A synchronizer ring is provided that has a periphery with at least one tab extending at least partially radially at the periphery. An annular hub has at least one recess configured to receive the at least one tab to axially align the synchronizer ring with the hub. The recess and the tab define a clearance when the tab is received in the recess. A damping material is provided in the clearance such that the damping material contacts the annular hub when the synchronizer is moved about the axis of rotation relative to the annular hub. Such movement may occur during engagement of an annular sleeve with a gear whose speed is synchronized with the sleeve by the synchronizer ring.
