ABSTRACT:
A free ring synchronizer is provided with improved resilient means for circumferentially biasing a pair of axially spaced friction rings in opposite directions. The resilient means is a coil spring mounted within a shiftable coupling collar interposed between the friction rings. The coil spring includes radially extending legs for engaging oppositely extending pins which are fixed to the friction rings and pass through openings in the shiftable coupling collar. Coacting blocking surfaces are provided on the pins and in the coupling collar openings and are releasably held in contact by the reaction of the legs against the pins.
