ABSTRACT:
In a gear-type change-speed transmission with synchronized reverse speed, the corresponding pair of gears consists of a loose gear which is adapted to be clutched with the driving shaft and of a fixed gear of the output shaft; an intermediate gear is adapted to be engaged between the loose gear and the fixed gear by means of a pivot lever; the intermediate gear meshes constantly with the loose gear, is brought in a first shifting phase into engagement with the fixed gear over a small partial area of its tooth width load-free and during the further engagement of the reverse speed is engaged into the fixed gear over its full tooth width. Only thereafter the loose gear is coupled torque-transmittingly with the input shaft.
