Aluminum wheels have a one-piece, two-piece and three-piece. Two-piece aluminum wheel from the inside is a member and an outer member nailed or welded on. Be careful when welding, since welding two things does not necessarily guarantee roundness.
Three-piece aluminum wheels by the center of a cylindrical member and two pieces of composition, and screwed together with aircraft-grade screws. In order to reduce the quality of a lot of three-piece forged aluminum wheels using pieces. Three-piece structure for manufacturers to small volume manufacturing provides greater flexibility.
Safety
For high-speed car, the wheel deformation due to high temperature produced by tire braking, braking efficiency and decreased phenomenon is common. The thermal conductivity of aluminum alloy is three times larger than the steel, iron, etc., natural cooling effect is much better, thus increasing the braking performance, improve the life of the tire and the brake disc, the effective protection of the safe driving of the car.
Cozy
Cars equipped with alloy wheels are generally used radial tire. Cushioning and shock absorption better than ordinary tire radial tire. In this way, the car on uneven road or high speed, comfort will be greatly enhanced.
Energy Saving
Because of light weight alloy wheels (with the same specifications of the aluminum or steel wheels difference of about 2kg), manufacture of high precision, so the high-speed rotation distortion, inertial resistance is also small. This will help improve the performance of vehicles traveling straight, reduce tire rolling resistance, thus reducing fuel consumption.
