ABSTRACT:
A change-speed gear in group-type construction with a main gear-shifting mechanism and a group gearing connected thereto. A primary shaft drives a main shaft selectively via gears of an intermediate shaft or by direct coupling of the primary shaft and the main shaft and at different speeds. The gears of the main shaft furthermore mesh with gears of the group stages of the group gearing; these latter gears are freely rotatably mounted on an output shaft and can be coupled therewith. To eliminate components and to provide a compact change-speed gear, one gear of the intermediate shaft, in addition to its function as shifting gear of the main gear-shifting mechanism, at the same times performs the function of a reversing gear for the reverse group of the group gearing.
