Hydraulic control method and system for self-correction of walking deviation of excavator
The invention discloses an excavator walking deviation self-correction hydraulic control method and a control system thereof, and belongs to the technical field of engineering machinery. The defect that in the prior art, walking deviation exists in the walking process of a left-right walking motor of a traditional excavator is overcome. The main body structure of the hydraulic system comprises a compensation system, a control system, a left pump, a right pump, a right walking valve, a left walking valve, a linear walking valve, a left walking motor and a right walking motor, the compensation system is respectively connected with the left walking motor and the right walking motor, and the control system is respectively connected with the left walking motor and the right walking motor. The left pump is connected with the left walking valve and the linear walking valve, the right pump is connected with the right walking valve through the linear walking valve, the left walking valve is further connected with the left walking motor, and the right walking valve is further connected with the right walking motor. The invention is mainly applied to engineering machinery such as excavators.
