The main causes of automobile wheel hub damage include material defects, processing flaws, improper use, and environmental impacts. Substandard materials or pores and shrinkage cavities formed during casting will reduce the strength of the wheel hub, making it prone to fracture under stress; surface cracks during processing, uneven mounting surfaces, or improper heat treatment can also lead to structural fragility. Environmental factors such as corrosion from rainwater and deicing agents or high-temperature aging of the brake system will accelerate the degradation of metal properties, while continuous vibration may cause fatigue fractures. In addition, tyre problems (such as abnormal air pressure or air leakage) will weaken the buffering effect, allowing impact forces to be directly transmitted to the wheel hub. It is best to choose high-strength wheel hubs that meet standards, avoid overloading and aggressive driving, regularly check the tightness of bolts and the surface condition of wheel hubs, promptly clean corrosive substances, and ensure proper brake cooling to extend the service life of wheel hubs and ensure driving safety.
