The invention discloses a double-linkage four-wheel steering chassis. The chassis is high in integration degree and small in size, a double-linkage four-wheel steering mechanism is adopted, tires on each side are steered through cooperation of a set of lead screw sliding tables and a steering pull rod, the complexity degree of the mechanism is simplified, and the machine cost is reduced; every twotires adopt one set of power source to provide steering power, the number of motors is reduced, all sets of sensors are concentrated near the lead screw sliding tables, and the control difficulty islowered.
本发明公开了一种双联动四轮转向底盘。该机器集成化程度较高,体积小巧,采用双联动四轮转向机构,每侧轮胎各由一组丝杠滑台配合转向拉杆负责轮胎转向,简化了机构的复杂程度,降低了机器成本;每两个轮胎采用一组动力源提供转向动力,减少了电机数量,将各组传感器集中于丝杠滑台附近,降低了控制难度。
