With the advancement of science and technology and the continuous development of vehicle design, the technology of axles is also constantly innovating and upgrading.
1. Material upgrade: Early axles were mostly made of wood or iron materials. Although these materials have certain strength and rigidity, they are heavy and easy to corrode. With the emergence and widespread application of alloy materials, the weight of axles has been greatly reduced, and the strength and durability have also been significantly improved.
2. Bearing technology: Bearings are the key connecting parts between axles and car bodies. Early bearings mostly used sliding friction, which had high friction resistance and easy wear. Modern bearings mostly use rolling friction, which not only has low friction resistance and long life, but also can effectively reduce vibration and noise.
3. Drive system: With the popularity of electric vehicles and hybrid vehicles, the drive system of axles is also undergoing revolutionary changes. Traditional mechanical transmission methods are gradually replaced by electric transmission, and the motors and controllers on the axles have become the new driving core.
