Wheel selection and maintenance
First, do not blindly increase the hub. Some people want to improve the car's performance and increase the hub. Under the condition that the outer diameter of the tire is constant, the big wheel hub must match the wide and flat tires. The lateral swing of the car is rather small, and the stability is improved. Lightly brushed. However, the flatter the tire, the thinner the thickness, the worse the shock absorption performance, and comfort will be sacrificed. In addition, there is a slight stumbling block of stone and the tires are easily damaged. Therefore, blindly increasing the cost of the wheel can not be ignored.
Nowadays, the most immersive aluminum alloy wheels, compared with the iron cast wheels in the past, each aluminum alloy wheel is 2kg lighter than the same size steel wheel hub, and 4 cars can save 8kg weight. According to the Japanese experiment, the weight of a 5-seater car is reduced by 1kg per year, saving about 20L of gasoline per year. Moreover, the roundness is good, the deformation resistance has been greatly improved, and the running balance performance is good, which helps to eliminate the general body length and the steering wheel jitter. The loss of the car power is small, it runs fast, and its heat dissipation is good. Thermal conductivity is 3 times that of steel.
Regarding the maintenance of the hub, Zeng Fanzhi, technical director of Hubai Cheyou Club, gave several opinions: When the hub temperature is high, it should be allowed to cool naturally and then cleaned. Do not use cold water to clean; when the hub is stained When it is difficult to clear the asphalt, if the general cleaning agent does not help, use a brush to try to clear, but do not use a hard brush, especially iron brush, so as not to damage the hub surface; if the vehicle area is wet or near the waterfront, the wheel should be diligent Wash to avoid salt corrosion on the aluminum surface. When necessary, it can be waxed and maintained to keep its luster.
