装载机在进行铲装作业时，有些驾驶员经常采用冲击料堆的方法进行铲装。此做法的结果是当装载机快速接近料堆时，超越离合器（见附图）仅中间输入轴３工作，铲斗触及料堆后的瞬间，中间输入轴转速急降，负荷剧增，造成隔离环８、滚柱９与外环齿轮１２因相互卡死而无法脱开，致 Loaders in the shovel operation, some drivers often use impact pile heap method. The result of this approach is that when the loader is approaching the stockpile quickly, the overrunning clutch (see the figure) only works with the input shaft 3 in the middle. The moment the bucket touches the stockpile, the input shaft speed drops sharply and the load increases sharply, resulting in isolation Ring 8, roller 9 and the outer ring gear 12 due to mutual locking and can not be separated, caused
