Patent ID: 8550226

Claim:
A transmission synchronizer assembly comprising: a synchronizer ring having a periphery with at least one tab extending at least partially radially at the periphery; an annular hub having an axis of rotation and at least one recess configured to receive the at least one tab to axially align the synchronizer ring with the hub; wherein the at least one recess is sufficiently sized so that the annular hub and the at least one tab define an angular clearance between the annular hub and the synchronizer ring that allows relative angular movement of the annular hub and the synchronizer ring about the axis of rotation when the at least one tab is received in the at least one recess; and a damping material on an axially-extending surface of the at least one tab in the angular clearance such that the damping material contacts an axially-extending surface of the annular hub that faces the axially-extending surface of the at least one tab when the synchronizer is moved about the axis of rotation relative to the annular hub.
