Abstract
A double-acting baulkring-type synchronizer ( ) includes fiction surfaces ( and ) and jaw teeth and jaw teeth ( ) for synchronizing and positively connecting forward and reverse gears ( ) to a shaft ( ). Initial engaging movement of a shift sleeve ( ) from a neutral position activates pre-energizers ( or ) effect engagement of the friction surfaces for engaging blocker surfaces ( ) that prevent asynchronous engagement of the jaw teeth. The pre-energizers include clearances and centering forces to prevent momentary engagement of the friction surfaces associated with the reverse gear and the forward gear when the shift sleeve is moved back to the neutral position from a position of engaged the jaw teeth ( or ) associated respectively with the forward and reverse gears.
