Abstract
A baulkring-type synchronizer ( ) includes cone clutch friction surfaces ( and ) for frictionally synchronizing gears ( ) to a shaft ( ), and jaw clutch teeth ( ) engagable with jaw teeth defined on opposite ends of splines ( ) for positive connecting the gears to the shaft. Pluralities of rigid self-energizing members ( ) are drivingly interposed between blocker teeth ( ) affixed to baulkrings ( ) and self-energizing ramp surfaces ( ) defined on an outer circumference of a hub affixed to the shaft ( ). A shift sleeve ( ) is slidably splined to the hub ( ) and is moved by a shift force and an additive force provided by the self-energizing ramp surfaces. Both forces react against the blocker teeth to engage the friction surfaces. A plurality of circumferentially spaced apart c-shaped rigid members ( ) disengage the friction surface of one baulkring prior to engagement of the friction surface of the other baulking in response to the shift sleeve ( ) being moved by the shift force from a position having the jaw teeth thereof engaged with the jaw teeth affixed of one drive toward a position for engaging the jaw teeth thereof with the jaw teeth affixed to the other drive.
