Abstract:
The invention relates to a hydrostatic multi-motor drive (1) with a hydraulic pump (2) and at least one first pair of hydraulic motors. The two hydraulic motors (6, 7) of the first pair of hydraulic motors are connected to one another in series by means of a first working line section (12). A bypass line (15) is provided which connects a first connection (11; 10) of the hydraulic motor (7; 6), which is upstream in relation to a volumetric flow generated by the hydraulic pump (2), to a second connection (9; 8) of the downstream hydraulic motor (7; 6). A first valve unit (18) which interrupts the first bypass line (15) is arranged in the bypass line (15). A first minimum pressure maintaining device (25; 26) for maintaining a minimum pressure at the upstream connection (11; 10) of the downstream hydraulic motor (7; 6) is also arranged in the bypass line (15).
