When the car is running on the uneven road, the leaf spring is easy to break. A few blades break, generally will not have a great impact on the driving, but if more fragments, leaf springs can not bear the load, the body is seriously inclined, and even the wheel will touch the wing plate bracket or the bottom of the car, resulting in inability to drive. In the course of driving, if this kind of fault occurs and maintenance conditions are available, the leaf spring assembly can be removed, the two ends of the broken steel plate can be slanted by grinding wheel, surfacing by electric welding machine, and then grinding the weld smooth with grinding wheel, and finally installed and reused.

如果没有维修条件，可用千斤顶把沉落这一边的车架边梁顶起，并根据折断的程度和部位，在钢板弹簧、车架和车桥间垫上木板，再用铁丝或绳索捆牢，或用钢板弹簧卡子固定。经过这样应急处理后，可以用低速档缓慢行驶，到有修理条件的地方进行修理。

If there is no maintenance condition, jack can be used to lift the side beam of the frame on the side of the sinking, and according to the degree and position of breakage, in the leaf springs, frame and bridge between the mat, and then tied with wire or rope, or fixed with leaf spring clip. After this emergency treatment, you can use low-speed slow driving to repair the conditions to the place.
