  • Synchronizing device having spring pin thrust members
    Patent number: 4125179
    Abstract: A synchronizing device is provided having improved thrust members supported by a pair of friction rings and releasable associated with a shiftable clutch collar. The thrust members are in the form of compressible C-shaped spring pins frictionally disposed in suitable openings in the shiftable clutch collar. The spring pins include integral ribs adapted to cooperate with suitable openings in the clutch collar to prevent the friction rings from drifting when the clutch collar is in its neutral position and also provide an operator with adequate "feel" when effecting a shift.
