Hub Axle Nut

Industry knowledge

Why do I need to use specific torque values when tightening hub axle nuts?

When tightening hub axle nuts, it is critical to use specific torque values for several reasons:
The specific torque value ensures optimal tightening force between the hub axle nut and the hub. The main function of the hub axle nut is to fix the wheel and hub to prevent the wheel from falling off or loosening during driving. If the torque value is too small, the nut may not be able to fully compress the wheel hub, resulting in insufficient tightening force and increased driving safety hazards; if the torque value is too large, the nut or wheel hub may be damaged, or even the bearing may be damaged, affecting the normal driving of the vehicle.
Using specific torque values can help reduce wear on the nut and threads. During the tightening process, if the torque value is too large or too small, unnecessary friction and wear will occur between the nut and the thread, thus affecting the service life of the parts. Using the proper torque value can reduce this wear and extend the life of the nut and hub.
The specific torque value can also ensure the stability and comfort of the vehicle. If the tightening force of the hub axle nut is uneven or insufficient, it will cause the wheel to vibrate or shake during driving, affecting the stability and comfort of the vehicle. Hub axle nut manufacturers use specific torque values to ensure uniform and moderate tightening force between the wheel and hub, thereby improving the vehicle's driving performance.
It is crucial to use a specific torque value when tightening the hub axle nut. It not only ensures the driving safety of the vehicle and reduces the wear of components, but also improves the driving performance and stability of the vehicle. Therefore, when performing vehicle repairs and maintenance, operations should be performed strictly in accordance with the specifications and standards provided by the vehicle manufacturer.

Why do materials like titanium alloy and 7075 aluminum perform so well in hub axle nuts?

Materials such as titanium alloys and 7075 aluminum perform well in hub axle nuts, mainly due to their unique physical and chemical properties that make them ideal for manufacturing parts that require high strength and durability, such as hub axle nuts. .
Titanium alloy is a lightweight and high-strength material. Its density is relatively low, but its strength is very high, which allows the titanium alloy hub axle nut to significantly reduce the weight of the entire vehicle while maintaining sufficient strength. Reducing weight not only improves a vehicle's fuel economy, but also helps improve its handling and acceleration.
Titanium alloy has excellent corrosion resistance and oxidation resistance. During vehicle use, the hub axle nut will often come into contact with corrosive substances such as water, mud, and salt. If the material is not corrosion-resistant, it will easily lead to problems such as rust and breakage of the nut. Titanium alloy can resist the erosion of these corrosive substances, thereby maintaining stable performance and extending the service life of the nut.
Titanium alloys also have good thermal stability and fatigue resistance. During high-speed driving and frequent braking, the hub axle nut is subject to high temperatures and alternating stresses. If the material has poor thermal stability or insufficient fatigue resistance, it will easily lead to nut failure. Titanium alloy can maintain stable performance under these harsh conditions, ensuring the safety and reliability of the nut.
7075 aluminum is also a high-performance aluminum alloy material. It has extremely high strength and hardness while maintaining a low density. This allows the 7075 aluminum wheel hub nut to be lightweight while maintaining sufficient strength. In addition, 7075 aluminum also has good processing and welding properties, making the manufacturing process more efficient and economical.
Materials such as titanium alloy and 7075 aluminum perform well in hub shaft nuts, mainly because they have excellent performance characteristics such as light weight, high strength, corrosion resistance, thermal stability and fatigue resistance. These characteristics enable them to maintain stable performance in various harsh environments and ensure the safety and reliability of the hub axle nut, thereby extending the service life of the vehicle and improving performance.
