Abstract
A gear shifting device for change-speed gearboxes having a forward gear and a reverse gear in a common shift plane, including a housing, a shifter rod slidably supported within the housing, a shifter fork having a bridge axially slidable on the shifter rod, and a shifter arm having a selector finger selectively engageable with the shifter fork. The shifter arm moves in a first direction from a neutral position to select the forward gear and in a substantially opposite second direction from the neutral position to select the reverse gear. A first pin and cam connection is provided between the shifter arm and reverse gear so that movement of the selector finger in the first direction of the shift plane from the neutral position engages forward gear while reverse gear is not affected by movement in the first direction. A second pin and cam connection is provided between the shifter arm and forward gear so that movement of the selector finger in the second direction of the shift plane from the neutral position engages reverse gear and the forward gear is not affected by movement in the second direction.
