Soft start hydrostatic driving system

The utility model discloses a soft start hydrostatic driving system, which comprises a motor, a variable pump, a motor and a control system, the control system comprises a pressure reducing overflow valve, an electromagnetic reversing valve, an initial damping hole, a parallel flow damping hole, a hydraulic control reversing valve and an energy accumulator; motor and variable pump connection. Theutility model has the following technical effects: firstly, the control is simple, stable and reliable, and the soft start performance is better; secondly, the problem that in the prior art, the pressure rising rate is reduced in the later period of control oil pressure rising is solved, and the control oil pressure and the system speed can reach preset target values in time; 3, the safety protection is complete. The pressure reduction overflow valve is used for limiting the pressure of a control system and is of an integrated structure. However, in order to achieve the purpose, the pressure reduction overflow valve c
