ABSTRACT:
A transmission synchronizer includes a strut and blocker ring engagement system wherein the strut is retained by the blocker rings in all of its axial positions against centrifugal and spring forces on the strut. The slots in each blocker ring are fully enclosed, and thus are disposed for total containment of the opposed ends of the struts. In a preferred embodiment the strut includes a pair of opposed axially spaced, radially extending bearing surfaces, each disposed for axially bearing against one side of a blocker ring, wherein each of the bearing surfaces is distinct from the slot engaging ends of the strut. Thus each bearing surface defines an inwardly stepped wall relative to one of the slot engaging ends of the strut.
