Forged aluminum wheel passenger trucks (wheel hub) has the following advantages:
1, to save fuel. Installation forged alloy wheels, because of the reduced weight of the vehicle, reducing the rotational inertia of the wheel, so that vehicle acceleration performance, and a corresponding reduction in the braking energy demand, which reduces fuel consumption, coupled with unique forged aluminum wheels air flow and rolling resistance, so the rate of one hundred kilometers to save the test to save two liters per hundred kilometers oil (replace forged aluminum alloy wheels and air-conditioning after 100 km fuel consumption than the forged aluminum wheel is not for no air conditioning fuel consumption test, the former than the latter low 2.5 liters fuel consumption).
2, its light. Weight forged aluminum wheel hub is only about half of the iron weight to 22.5X8.25 the example; forged aluminum wheel is 24 kg, iron hub is at least 50 kg.
3, reduced brake maintenance costs. Because the characteristics of forged aluminum alloy wheels fast bulk temperature, low temperature normal driving, the brake system is not so high-temperature materials and accessories have excellent protective effect, thus greatly reducing the brake system maintenance costs.
4, tire wear by 26%. Because the characteristics of forged aluminum alloy wheels, its balance is 0, not easily deformed, fast bulk temperature (normal running temperature of 20-30 degrees lower than the iron hub) better protection of the suspension system, so the tire wear greatly reduced , so that each tire to run more than ten thousand km range 5-8).
5, high carrying capacity. The forged aluminum wheel hub bearing capacity is five times the normal iron. Forged aluminum wheels to withstand 71,200 kg after the deformation 5 cm. Iron wheel is exposed only to 13,600 kg has been deformed after 5 cm, in other words, the strength of forged aluminum wheel hub than five times the iron.
6 beautiful shape. Forged aluminum wheel design large degree of freedom model can be combined, so that cars, round one, with perfect.
8, the impact test. Japanese JWL test simulates a vehicle to the roadside when the stone hit over 50 km, equivalent to 910 kg weight falling from a height crashed into the tire and wheel. According to the U.S. aluminum forging technology center for the Japanese standard test results: forged aluminum wheels that only minor damage, while the iron hub extent of the damage is very serious. Cast aluminum alloy wheels broken into two parts.
9, to improve driving comfort. Because the characteristics of forged aluminum alloy wheels, after installation the direction of lighter traffic sense, particularly smooth at high speeds, thereby improving driving pleasure.
