HYDROSTATIC TRACTION DRIVE AND VEHICLE WITH SUCH A TRACTION DRIVE

A hydrostatic traction drive includes a pressure medium source configured to drive four hydromotors connected as pairs in series, the pairs arranged parallel to each other. In a respective pressure medium flow path between the hydromotors of a series, a pressure medium volume flow is extracted which...

Beschreibung
Zusammenfassung:	A hydrostatic traction drive includes a pressure medium source configured to drive four hydromotors connected as pairs in series, the pairs arranged parallel to each other. In a respective pressure medium flow path between the hydromotors of a series, a pressure medium volume flow is extracted which is diverted via a respective valve device to a pressure medium sink to bypass the respective downstream hydromotor. The hydrostatic traction drive also includes a control valve configured to balance the pressure on pressure differences between the pressure medium flow paths, in particular on a steering movement of an articulated steering. The control valve is configured to connect the pressure medium flow paths together hydraulically.
