重型汽车螺栓松动成因与防松探讨

Heavy duty truck bolt looseness causes and locking

重型汽车生产装配中各零部件大多使用螺栓联接,特别是重型汽车底盘使用了大量的高强度螺栓联接,这些螺栓联接的质量将直接影响整车的行驶安全性,螺栓松动与断裂将导致汽车停止行驶、翻车、损坏车辆甚至危及人的生命安全。文章对螺栓联接松动问题产生的原因进行了理论分析,并相应提出几种有效防松方法。

Heavy duty truck parts in the assembly of production mostly use the bolt connection, especially heavy car chassis use a lot of high strength bolt connection, the bolt connection will directly affect the quality of the vehicle driving safety, bolt loosening and fracture will result in the car to stop driving, rollover, damage to vehicles, and even endanger people＇s life. Article on the causes of loose bolt coupling problems are analyzed in theory, and put forward several effective corresponding locking method.
