Analysis and comparison of forged aluminum alloy rims and ordinary truck iron rims
1. Light itself. The weight of a forged aluminum ring is only half the weight of an iron ring, taking 22.5X8.5 as an example; the forged aluminum ring is 25 kg, and the iron ring is at least 48 kg.
2. Save fuel. After the forged aluminum ring is installed, the weight of the whole vehicle is reduced, the rotational inertia of the wheels is reduced, the acceleration performance of the car is improved, and the demand for braking energy is correspondingly reduced, thereby reducing fuel consumption, plus the unique air of the forged aluminum ring Flow and rolling resistance, so the saving rate of 100 kilometers test is at least 2 liters of fuel per 100 kilometers (the fuel consumption of 100 kilometers after replacing the forged aluminum ring and using the air conditioner is compared with the fuel consumption test of the forged aluminum ring without the air conditioner, the former is better than the latter The fuel consumption is lower by 2.5 liters).
3. Tire wear is reduced by 26%. Due to the characteristics of the forged ring, its balance value is 0, it is not easy to deform, and the temperature dissipation is fast (normal driving temperature is 20-30 degrees lower than the iron ring), which protects the suspension system better, so the wear of the tire is greatly reduced, so Each tire runs 50,000-80,000 kilometers more).
4. The maintenance cost of the brake is reduced. Due to the characteristics of forged aluminum rims with fast heat dissipation and low normal driving temperature, it has an excellent protective effect on materials and accessories that are not resistant to high temperatures in the brake system, thereby greatly reducing the maintenance cost of the brake system.
5. High load capacity, the load capacity of forged ring is 5 times that of ordinary iron ring. The forged wheel only deforms 5 cm after bearing 71,200 kg. The iron ring has been deformed by 5 cm after bearing only 13,600 kg. In other words, the strength of the forged rim is 5 times stronger than that of the steel rim.
6. Improve driving comfort. Due to the characteristics of the forged wheels, the driving direction is lighter after installation, and the high-speed driving is particularly stable, thereby improving the driving pleasure.
7. Good safety. For high-speed cars, it is not uncommon for tires to puncture at high temperatures and reduce braking efficiency due to tire friction and braking. The thermal conductivity of aluminum alloy is three times that of steel and iron. In addition, due to the structural characteristics of aluminum alloy wheels, it is easy to dissipate the heat generated by tires and chassis into the air. Even in the case of long-distance high-speed driving or continuous braking on downhill roads, the car can maintain a proper temperature. Not only can the tires and brake drums be less prone to aging due to frequent high temperatures, but also can reduce the rate of puncture.
8. Impact test. The Japanese JWL test simulates a truck hitting a curbstone over 50 kilometers per hour, which is equivalent to a weight of 910 kilograms falling from a height and hitting tires and wheels. According to the results of the Japanese standard test conducted by the magnesium-aluminum forging technology center: the forged wheels were only slightly damaged, while the iron rims were damaged very seriously. The cast aluminum alloy wheel broke into two parts.
9. Beautiful appearance. The forged aluminum ring has a large degree of freedom in appearance design, and can be combined with the model to achieve a perfect car and wheel.
