When a car tire is punctured and leaks, it is necessary to replace the spare tire and go to the auto repair shop to repair the tire. To replace the tire again, the Wheel Lug Bolts need to be removed and tightened. So should the wheel bolts be tightened?
The wheel fastening methods can be roughly divided into the following two types, namely the Wheel Lug Bolts method and the wheel nut method. The Wheel Lug Bolts connection method is mainly suitable for European models. Its advantages are that when the bolts are damaged, they are easy to replace, and only the bolts need to be purchased; the structure on the wheel hub side is simple, which is beneficial to cost; the disadvantage is that the workability when installing the wheel is not good; the method of tightening the bolts is disadvantageous in terms of torque attenuation compared to the method of tightening the nuts.
Some people believe that the Wheel Lug Bolts are used to tighten the tires. When the tires are running at high speed or under dynamic load, the external load is large, so they should be pre-tightened with a larger torque. It is even necessary to tighten the bolts over yield like other positions on the chassis. So, what are the dangers of blindly tightening it? When tightened too much, the Wheel Lug Bolts will enter the yield state and produce irreversible plastic deformation. Bolts that have undergone plastic deformation cannot be reused many times, which means that the wheel bolts also need to be replaced every time the wheel is replaced, which is very inconvenient.
When tightened too much, the axial preload of the Wheel Lug Bolts is very large. When subjected to a higher external load, the bolts are prone to fracture and failure. The internal thread of the hand piece is subject to a large load, and after repeated use, it is easy to slip. At this time, the hand piece can only be replaced, which is inconvenient to operate and costly.
Therefore, when we tighten the Wheel Lug Bolts, we must pay attention to using the correct tightening method. If you want to consult more information, please feel free to contact Ningbo Junwei Trading Co., Ltd.!
