发明名称 OIL PRESSURE SYSTEM FOR WHEEL LOADER
摘要 The present invention relates to an oil pressure system for a wheel loader, and more particularly to a wheel loader which includes an oil pressure system having a confluent circuit and reduces the occurrence of impact during a loading work. To this end, the present invention provides the wheel loader which is composed of an oil pressure circuit characterized by setting different cutoff pressure values with respect to a pair of left and right oil pressure pumps connected through the confluent circuit. Accordingly, the present invention can prevent loss of products loaded in a bucket due to an abrupt halt of a boom during the loading work and can remarkably reduce the impulse of the wheel loader by operating the boom at a remarkably low speed in comparison with the maximum speed when the boom approaches the maximum height in a rising process thereof during the loading work of the wheel loader.
