Abstract:
A shift control apparatus for use in a change-speed gearbox of motor vehicles; comprising:a housing;a selector shaft axially slidably and rotatably supported in the housing and operatively connected to a gear selector lever for axial displacement of the selector shaft to realize a preselection of a shifting lane and rotation of the selector shaft for shift into a selected gear;a shifter finger secured to the selector shaft and engaging slidable shifter forks or shifter bars; anda locking mechanism for preventing a misshift between a reverse gear and a forward gear in a same shifting lane, said locking mechanism including a transmission element mounted in fixed rotative engagement with the selector shaft and having a flanged edge, and a restraining member rotatable and axially moveable in parallel relationship to the selector shaft, said restraining member having a locking surface forming a deflector ramp configured for support of the flanged edge of the transmission element, said deflector ramp applying a force component in axial direction on the transmission element in synchronism to a rotational movement of the restraining member.
