<p>Hydrostatic drive system for a slip-steered vehicle (1), comprising two controllable hydraulic pumps (2, 3), which are preferably mounted on one and the same driven shaft, a pair of hydraulic motors (5, 6; 7, 8) at each side of the vehicle, each of the said pairs (5, 6; 7, 8) being connected with a hydraulic pump (2, 3) of its own, whereby each hydraulic motor (5, 6, 7, 8) is arranged so as to drive at least one wheel (9). The invention is characterized in that the two hydraulic pumps (2, 3) are connected to the corresponding pairs of hydraulic motors (5, 6; 7, 8) via a closed system of pipes and valves (10, 11, 12, 13; 14, 15, 16, 17), which permits switching over from hydraulic motors (5, 6; 7, 8) connected in parallel to hydraulic motors (5, 6; 7, 8) connected in series.</p> |
