Hydrostatic drive

Abstract

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