3.15 Hydrostatic Steering Control

3.15.1 General information

The hydrostatic steering control (HSC) is intended for control of guide wheels turn,

for steering effort decrease at tractor turning.  HSC consists of two dosing pumps 2 and 3
(figure 3.15.1), of  reverse valve switch 4, of two differential hydraulic cylinders 1, making
turning,  of feed pump 5 with  motor drive and of hydraulic fittings.

Hydraulic circuit diagram of HSC is shown in figure 3.15.1.

1 – hydraulic cylinder;  2 – dosing pump of forward motion;; 3 – dosing pump of re-

verse motion;  4 – reverse valve switch; 5 – feed pump; 6 – valve; 

Р

 – feeding; 

Т

 – drain; L

–left-hand turn; R – right-hand turn.
