METHOD FOR DRIVING FLOW RATE CONTROL OF WHEEL EXCAVATOR

摘要

The present invention relates to a method for controlling a driving flow rate of a wheel excavator for enhancing driving efficiency and reducing the number of rotation of an engine using the driving flow rate interflowed from two hydraulic oil pumps in the wheel excavator. In the method for controlling the driving flow rate of the wheel excavator for controlling a pump maximum driving flow rate of the wheel excavator by performing a pump interflow control through receiving pressurized oil discharged from the hydraulic pumps, the present invention comprises the steps of: performing a maximum flow control on the pumps by controlling a proportional control valve which controls the maximum flow of the hydraulic pumps after checking out an abnormality in the pump interflow control; receiving a flow value of a flow pump controlled by the proportional control valve; checking out an error if the flow value received while controlling the maximum flow of the pumps has an error; and compensating for the flow value by giving a weighted value to the checked error. The method for controlling the driving flow rate of the wheel excavator can reduce driving fuel consumption by decreasing the number of rotation of an engine, and also can reduce driving noise.
