Hydrostatic drive for vehicle, comprises system for saving free floating energy from braking process

摘要

The hydrostatic drive (1) comprises a high-pressure (10) and a low-pressure storage device (11) and a hydromotor (7) connected to a first (5) and a second operating duct (6). In a first position of a first valve (18) one operating duct (5) is connected to a high-pressure storage device (10). In the second position it is joined to the low-pressure storage device (11). In the first position of a second valve (19) the low-pressure storage device (11) is connected to the second operating duct (6) and in the second position it (6) is joined to the high-pressure storage device (10).
