ABSTRACT:
A shifting mechanism for reverse drive that slows the input shaft of a manual transmission in which a reverse gear wheel is shifted into engagement with reverse drive gearwheels disposed on a constant mesh gear and an output shaft. In order to slow the input shaft with the clutch disconnected, a shift fork is located on a rotatable and displaceable gear selector shaft that carries a shift finger and shift forks displaceably thereon. The shift fork is axially displaceable against the force of a spring relative to a bracket arm connecting the fork to the shift finger. An axial cam cooperates with an inclined portion of the shift fork and two radial arms contact stop surfaces on the housing cover and on an arm of the shift fork.
