Abstract:
The invention relates to a hydrostatic drive comprising at least one hydraulic pump (1) and a first and a second hydraulic motor (6, 25), which are respectively connected to said hydraulic pump (1) by means of two service lines (4, 41, 5, 5′) and whose absorption volume can be regulated by means of a regulator (40, 41). One respective hydraulic motor (6, 25) for a drive train is provided per respective right or left vehicle side. The regulators (40, 41) are actuated by a respective regulator piston (7, 26). The regulator pistons (7, 26) of both hydraulic motors (6, 25) can be subjected to a force by means of a common high pressure, which equals the highest pressure that prevails in the service lines (4, 41, 5, 5′) of both hydraulic motors (6, 25). Each force is opposed to a respective counter-force, which is generated by a control pressure in a control pressure chamber (11, 11′). The pressure in the control pressure chamber (11)/(11′) of the first and second regulator pistons (7)/(27) of the first and second hydraulic motors (6)/(25) can be reduced by means of first and second pressure regulating valves (17)/(30) in relation to a tank (20) and the first and second pressure regulating valves (17)/(30) are impinged by the respectively higher pressure of the first and second service lines (4, 5)/(4′, 5′) that are allocated to the first and second hydraulic motors (6)/(20), in the form of a controlled variable.
