ABSTRACT:
Transmission with double friction clutch, especially transmission for agricultural and/or vehicles for the construction industry, with two gear shifting groups, each one of which can be shifted by means of an associated clutch, with the groups being shiftable under load. One of the clutches is engaged by being spring-biased and engageable by means of a selectively acting pressure medium adapted to operate one or several cylinder/piston units. The effective operating surface of the pertaining piston is greater than the operating surface of the piston associated with the second clutch. The cylinders are connectible in such a way that on each piston in each shift position thereof the same shifting pressure is exerted.
