DEVICE AND METHOD FOR COMPENSATING THE RAISE SPEED OF THE BOOM LINK OF A WHEEL LOADER, CAPABLE OF CHANGING THE RELEASE TIMING OF ELECTROMAGNET FOR AUTOMATIC BOOM RAISE USING THE RAISE SPEED OF A VARIABLE BOOM

摘要

PURPOSE: Device and method for compensating the raise speed of the boom link of a wheel loader are provided to enable a boom link to stop on a driver-established dump position since the release timing of electromagnet for automatic boom raise changes.;CONSTITUTION: A device for compensating the raise speed of the boom link of a wheel loader comprises a wheel loader(100), a first calculating unit, and a second calculating unit. The first calculating unit calculates an angular velocity using an angle, which is extracted from an angle detecting unit(120) by a controller. The first calculating unit calculates the rising average angular-velocity of a boom link(110). The second calculating unit uses the rising average angular-velocity and the extracted angle from the angle detecting unit. The second calculating unit calculates the release angle of electromagnet for stopping the boom link on an established dump position.;COPYRIGHT KIPO 2011
