The invention relates to a double-front-axle full-hydraulic steering system which comprises a hydraulic device and a steering transmission device powered by the hydraulic device. High-pressure oil sucked and pumped out from an oil tank through an electric hydraulic steering pump enters a full-hydraulic steering machine and then enters a first-shaft steering power-assisted cylinder and a second-shaft steering power-assisted cylinder through a working oil port; and a steering transmission rod system is formed among a first rocker arm assembly, a second rocker arm assembly, a third rocker arm assembly, a first longitudinal pull rod assembly, a first middle pull rod, a second middle pull rod and a second longitudinal pull rod assembly and is transmitted to a first-shaft left steering knuckle arm and a second-shaft right steering knuckle arm, so that wheel rotation is realized. A light, flexible, reliable and stable steering function is provided for a large-tonnage battery-replacing dumper in a steel mill; full-hydraulic power-assisted steering is adopted, and the steering requirement of a large-tonnage wide-body dumper of a steel mill is completely met.
本发明涉及一种双前轴全液压转向系统,包括液压装置、以及由液压装置提供动力的转向传动装置;本发明通过电动液压转向泵从油罐吸入并泵出的高压油液进入全液压转向机后经过工作油口进入一轴转向助力缸和二轴转向助力缸中,以及通过第一摇臂总成、第二摇臂总成、第三摇臂总成、第一纵拉杆总成、第一中间拉杆、第二中间拉杆、第二纵拉杆总成之间组成转向传动杆系传递到一轴左转向节臂和二轴右转向节臂上,从而实现车轮转动,为钢厂大吨位换电自卸车提供轻便、灵活、可靠稳定的转向功能;本发明采用全液压助力转向完全满足钢厂大吨位宽体自卸车转向需求。
