Product description
Compared with steel car wheels, the advantages of aluminum alloy wheel hub have?
1. fuel efficiency.The average aluminum alloy wheel hub 2 kg lighter than the steel wheels of the same size, a car with five province great 10 kg weight.According to Japanese experiment, five cars each reduce weight 1 kg, about a year or save 20 l petrol.A research report published by the American society of automotive engineers, points out that aluminum alloy wheel hub although more expensive than ordinary steel wheels, but ran to 20000 km per car, the fuel savings by foot Qin reached back to costs.
2. increase the engine life.Engine load and negatively correlated with the life of the engine, the greater the load the shorter service life.For aluminum alloy wheel hub lighter than steel wheel, therefore can prolong engine life.
3. good heat dissipation.3 times of the heat transfer coefficient for the aluminum alloy steel, good heat dissipation effect.Long high-speed, can also keep the tyres in the appropriate temperature, the brake drum and wheel is not easy to aging, increase longevity, reduce the chances of a flat tire.
4. high precision.Aluminum alloy wheel hub of the true circle accuracy up to 0.05 mm, balance performance is good, operation is helpful to eliminate the phenomenon of the steering wheel jitter.
5. strong and durable.Aluminum alloy wheel hub impact resistance, resistance to tension and thermal strength of the steel wheel is higher.This is aluminum alloy play an important role in the defense industry, aviation industry one of the reasons.
6. beautiful.General steel wheel due to the limited production, form is dull, lack of change;Aluminum alloy wheel hub has a wide variety of design, add luster, color, effect is good, so as to improve the car's value and aesthetic feeling.
