DEVICE FOR REDUCING IMPACT DURING TRAVELING OF CONSTRUCTION MACHINE AND METHOD FOR CONTROLLING CONSTRUCTION MACHINE USING SAME

摘要

A travelling shock reducing device for construction machinery, includes a travel manipulation portion to generate a pilot pressure for controlling an amount of a hydraulic oil discharged from a hydraulic pump to be supplied to a travel motor of the construction machinery, a sensing portion configured to detect a manipulation change of the travel manipulation portion, a pressure reducing valve installed between the travel manipulation portion and the hydraulic pump to control the pilot pressure supplied to the hydraulic pump, and a controller receiving information on the manipulation change from the sensing portion, and configured to control an operation of the pressure reducing valve such that the pilot pressure is gently increased when the manipulation change is greater than a predetermined value.
