ABSTRACT:
A locking synchronizer for transmission shifts, has a sliding sleeve carrier and a gear revolving at different speeds of rotation coupled together upon attaining synchronism via an axially slidable, annular sliding sleeve. A coupling tooth array of the sliding sleeve engages a corresponding spur gearing of the sliding sleeve carrier as well as a coupling tooth array of the gear, with engagement pins positioned between the sliding sleeve carrier and sliding sleeve. Portions of the gear form with portions of the synchronizing ring a coupling capable of transmitting force and with locking teeth on the synchronizing ring for the temporary prevention of the axial movement of the sliding sleeve, whereby the preventive action is cancelled even during existing difference in speed of rotation as a function of the warming on the synchronizing ring or a defined unlocking force which acts transversely to the motion of the sliding sleeve on the locking teeth of the synchronizing ring.
