Analysis and Comparison of Forged Aluminum Alloy Wheels and Ordinary Trucks

1. own light Forged aluminum ring weight is only equivalent to half the weight of the ring to 22.5X8.5 for example; forged aluminum ring for 25 kg, the ring for at least 48 kg.

Save fuel. After the installation of forged aluminum ring, due to the reduction of the weight of the vehicle, reducing the rotation of the wheel inertia, the vehicle acceleration performance, and a corresponding reduction in the demand for braking energy, thereby reducing fuel consumption, plus forging aluminum ring unique air Flow and rolling resistance, so 100 km test savings rate for every 100 km to save a minimum of 2 liters of oil (replacement forging aluminum ring and use air conditioning after 100 km fuel consumption than forged aluminum ring is not open air conditioning fuel consumption test, the former than after Low fuel consumption of 2.5 liters).

3. Tire wear reduced by 26%. Due to the characteristics of the forging ring, its balance is 0, not easy to deformation, loose temperature (normal running temperature lower than the ring 20-30 degrees) on the suspension system protection is better, so the tire wear greatly reduced Each tire to run more than 5-8 million km).

4. Brake maintenance costs are reduced. As the characteristics of forging aluminum ring temperature is very fast, the normal running temperature is low, so the brake system is not high temperature materials and accessories have excellent protection effect, thus greatly reducing the braking system maintenance costs.

5. Carrying capacity is high, forging ring bearing energy is 5 times the ordinary iron. Forged wheels in the bear after 71200 kg deformation of 5 cm. Iron ring only to withstand 13600 kg has been deformed after 5 cm, in other words, the strength of the forging wheel is more than 5 times the steel ring.

6. Improve the comfort of driving. Due to the characteristics of forged wheels, the installation of traffic after the direction of light, high-speed driving particularly stable, thereby enhancing the driving pleasure.

7. Good security. For high-speed cars, due to tire landing friction, braking and other high-temperature puncture, brake performance and other phenomena are common. The aluminum alloy heat transfer coefficient is three times the steel, iron, coupled with aluminum alloy because of its structural characteristics, easy to tire, car chassis generated by the heat scattered in the air. Even in the long-distance high-speed driving or downhill continuous braking in the case, the car can also maintain the appropriate temperature. Not only can make the tire and brake drum is not easy due to frequent high temperature and aging, can reduce the tire rate.

8. Impact test. Japan JWL test simulation of a truck to over 50 km crashed into the roadside stone, the equivalent of 910 kilograms of weight fell from a high crashed into the tires and wheels. According to the results of the Japanese standard test conducted by the Magnesium Aluminum Forging Technology Center, the forged wheels are only slightly damaged and the damage to the ring is very serious. Cast aluminum alloy wheels are broken into two parts.

9. handsome appearance. Forged aluminum ring design freedom, can be combined with models, so that the car, round one, filling the perfect.

To achieve the advantages of lightweight trucks

1. Low cost of use

(1) save fuel

After the installation of forged aluminum alloy wheels, not only the weight of the vehicle is reduced, but more importantly: the torque of the engine torque is reduced, the rotational inertia of the wheel is reduced, the vehicle acceleration performance is improved, and the demand for braking energy is reduced accordingly Reduced fuel consumption.

(2) good heat dissipation, extend tire life

Due to the low temperature of the tire during travel, thus extending the tire life of 26%; the same token, the wheel heat dissipation also makes the brake system maintenance costs.

(3) lightweight to bring better benefits

(4) aluminum wheel recycling value is high, a 24kg aluminum alloy wheel recycling value of 300 yuan.

2. Reduce carbon emissions

(1) Reduce carbon dioxide emissions in the manufacturing process: the production of 1 ton of steel carbon emissions of 1700kg; and the production of 1 ton of aluminum carbon emissions is 1500kg. Calculated in the production process of carbon emissions, the production of a 23kg aluminum wheel than the 46kg iron wheel material carbon emissions can be reduced by 87.4kg.

(2) Reduce fuel consumption Reduce carbon emissions: 1000 km per day, 1000 km / day × 2.5 liters (100 kg per 100 kg of fuel consumption) × 300 days × 0.785 kg (carbon emissions per liter of fuel) = annual reduction of carbon Discharge 5887kg.
