产品车在送车过程发生后桥右车轮抱死,导致车辆摆尾损坏事故,现场调查初步断定因轴承轴向间隙调整缺陷导致轴承发热烧结,造成后桥抱死。由此对轻型货车轮毂轴承调整工艺进行了分析,判定原因,提出改善方法。调整工艺改进后,消除了此缺陷造成的事故隐患。 After the vehicle was delivered, the right-hand wheel of the bridge was locked and the tail-mounted vehicle was damaged. The scene investigation preliminarily determined that bearing axial clearance adjustment caused the bearing to heat and sinter, resulting in rear axle locking. From this, the adjustment process of the light truck hub bearing is analyzed, the reason is determined and the improvement method is put forward. Adjustment process improvement, eliminating the defects caused by the accident hidden danger.
