Abstract
The invention relates to a drive system (1) having a first driving shaft (2) and having a second driving shaft (3). The second driving shaft (3) is connected to a cylinder barrel of a hydrostatic piston machine (4) in a torsionally rigid manner. The displacement volume of the hydrostatic piston machine (4) can be shifted by means of a shifting means (5), and the first driving shaft (2) can be mechanically coupled to the second driving shaft (3) through a clutch (6). The shifting means (5) and the clutch (6) can be actuated hydraulically and, for the purpose of actuation, are connected to a common control-pressure connection (11) or a common working-line connection (134).
