What Causes the Wheel Hub to Overheat?
1 Answers
The reasons for the wheel hub overheating may include excessively tight bearings, abnormal wear, or overheating of the brake drum. Below are detailed explanations regarding the causes of wheel hub overheating: 1. Overheating of the Wheel Hub: Overheating of the wheel hub could be due to excessively tight bearings or abnormal wear. The wheel hub (axle head) typically overheats because the bearing assembly is too tight or lacks proper lubrication. Excessive temperature can cause the lubricating grease inside to melt and leak out, affecting braking performance. In severe cases, it may even lead to bearing failure. 2. Overheating of the Brake Drum: Another possible cause of wheel hub overheating is the overheating of the brake drum, which may result in brake drag or drum rubbing. The brake drum is the part measured by the thermometer; it heats up with every brake application and is the area with the highest heat generation in the entire front wheel. The temperature of the brake drum is influenced by environmental temperature, driving speed, frequency of braking, vehicle weight, and road conditions.
