The invention discloses a crab-traveling vehicle four-wheel positioning tool. A first tool is used for determining the axle axis datum, a second tool is used for determining the perpendicularity of the rear axle axis and the frame axis, and a third tool and a fourth tool are used for assisting in completing front wheel toe-in and rear wheel toe-in adjustment. An adjusting method adopting the crab-traveling vehicle four-wheel positioning tool comprises the steps that the first tool is adopted for determining the axle axis datum, the second tool is adopted for assisting and adjusting a rear axle assembly based on the axle axis datum, and the perpendicularity of the rear axle axis, the perpendicularity of the front axle axis and the perpendicularity of the frame axis are guaranteed; a third tool and a fourth tool are adopted for assisting and adjusting a steering pull rod, the perpendicularity of a left rear tire and the axis of a rear axle is guaranteed, and a steering tie rod on the front side of a rear axle assembly is adjusted, so that a rear axle toe-in meets the technical index. A set of auxiliary tool is designed according to the structure of the crab-traveling vehicle, the perpendicularity of all axes is determined through the tool, the front wheel toe-in adjusting precision and the rear wheel toe-in adjusting precision are guaranteed, operation is easy, and the adjusting precision is high.

    本发明公开了一种蟹行车辆四轮定位的工装,第一工装用于确定车桥轴线基准,第二工装用于确定后桥轴线与车架轴线的垂直度,第三工装和第四工装用于辅助完成前、后轮前束的调整。一种采用蟹行车辆四轮定位工装的调整方法,采用第一工装确定车桥轴线基准→基于车桥轴线基准,采用第二工装辅助并调节后桥总成,保证后桥轴线、前桥轴线与车架轴线的垂直度→基于上述调整,采用第三工装和第四工装辅助并调节转向拉杆,保证左后轮胎与后桥轴线的垂直度→调节后桥总成前侧转向横拉杆,使得后桥前束满足技术指标。针对蟹行车辆结构,设计出一套辅助工装,并利用工装确定各轴线的垂直度,保证前、后轮前束调整的精度,操作简单,调整精度高。
