在汽车底盘修理过程中,发现有许多修理人员拆卸汽车转向立轴时采用的是用大锤直接敲打、氧乙炔烤和炉中加热锤击等方法。这样做有很多危害:转向立轴易弯曲、立轴座孔及前桥易变形,影响主销内倾。另外,立轴和前桥材质因加热受到影响,达不到原来材料的技术性能要求,其后果会影响汽车前轮定位和汽车行驶安全性。 During the process of repairing the chassis of the automobile, many repairers disassembled the steering shaft of the automobile and used the method of directly striking with a sledgehammer, baking with oxyacetylene and heating and hammering in a furnace. There are many hazards to doing so: steering vertical axis easy bending, vertical shaft hole and the front axle deformation easily affect the main pinnacle. In addition, the vertical shaft and the front axle material is affected by heating, can not reach the technical performance requirements of the original material, the consequences will affect the car front wheel positioning and car driving safety.
