Hydraulic device for solving differential speed and differential force of double-end locomotive multi-wheel vehicle

The utility model discloses a hydraulic device for solving the problem of differential speed and differential force of a double-head locomotive multi-wheel vehicle, which belongs to the technical field of hydraulic systems and comprises a hydraulic pump, a primary flow distributing and collecting valve, a first secondary flow distributing and collecting valve, a second secondary flow distributing and collecting valve, a first hydraulic motor, a second hydraulic motor, a third hydraulic motor and a fourth hydraulic motor. According to the utility model, the flow of the hydraulic pump flows into the first secondary flow distributing and collecting valve and the second secondary flow distributing and collecting valve through the primary flow distributing and collecting valve by means of forced average distribution, and the flow passing through the first secondary flow distributing and collecting valve enters the first hydraulic motor and the second hydraulic motor; the flow passing through the second two-stage f
