GEAR SHIFTING FOR POWER ASSISTED TRANSMISSION

摘要

A gear shift mechanism for providing a vehicle operator with a "feel" of a desired gear change being completed in a power operated gear unit. A drum disc connected to the gear shift lever is formed with a recess in which a locking pin of an actuator valve is engageable when the gear shift lever is operated to a shift position, thereby limiting further movement of the gear shift lever. A sensor device associated with the gear unit detects completion of the gear change and operates the actuator to retract the locking pin from the recess to allow further movement of the gear shift lever, as an indication to the vehicle operator that the intended gear change is completed, so that he may engage the clutch and apply gas.
