What are the domestic wheel hub brands?
1 Answers
Domestic wheel hub brands include CITIC Dicastal, Wanfeng Auto, Lizhong, Zhongnan Aluminum, and Ronal. The wheel hub is the rotating part of the tire's inner rim connected to the wheel center via spokes, which is the metal component mounted on the axle that supports the tire. The function of the wheel hub is to bear the rigid rotational inertia between the car and the tire and to provide braking force. Currently, the commonly used wheel hubs in automobiles are divided into steel wheel hubs and alloy wheel hubs. Wheel hubs on the market can be categorized into steel wheel hubs and alloy wheel hubs based on material. The main advantages of steel wheel hubs are their simple manufacturing process, relatively low cost, and strong resistance to metal fatigue. The disadvantages are their unattractive appearance, heavy weight, and susceptibility to rust. Aluminum alloy wheel hubs are primarily made of aluminum with appropriate additions of metals such as manganese, magnesium, chromium, and titanium. Compared to steel wheel hubs, they are lighter in weight, have better heat dissipation, and can extend tire life. Magnesium alloy is an alloy based on magnesium with the addition of other elements. Its characteristics include low density, high specific strength, large specific elastic modulus, good heat dissipation, excellent vibration damping, greater ability to withstand impact loads than aluminum alloy, minimal deformation at high speeds, low inertial resistance, which helps improve the car's straight-line driving performance, reduces tire rolling resistance, and consequently decreases fuel consumption.
