Abstract

The invention relates to a powershiftable multi-ratio reversing gear, especially for use in building machines. The clutches (17, 18, 23 and 26) are fitted between a fixed and a loose pinion. The loose pinions, which can rotate at relatively high speeds, are connected to the inner plates of a set of plates (39). The outer plates are fitted in the clutch housing of each of the clutches. This provides advantages for hydraulic operation of the clutches.
