Semi - trailer accessories knowledge popularization - steel ring

Semi trailer is the most common type of transportation, carrying capacity is strong, loading capacity is large, nearly all materials can be used to transport semi trailer, so it is loved by the majority of drivers. The following is an essential part of the popularization of the wheel for the majority of card friends - steel rings. The steel rim (also called the hub), is an essential part of the semi trailer. "hub" and "tire" are two entirely different parts. Let's learn about it with Semi Trailer Manufacturers.

Maintenance method of steel ring

1, when the temperature of the steel ring is elevated, it should be allowed to cool naturally before cleaning, do not use cold water to wash. Otherwise, the aluminum alloy steel ring will be damaged, and even the brake disc deformation and affect the braking effect. In addition, at elevated temperature with detergent to wash the steel ring, will make the surface of the steel ring chemical reaction, lose luster, affect the appearance.

3, to wash the hub, you can use paint diluent, wipe around the wound, remove dirt. The deepest part of the scrape is extremely difficult to remove dirt, then it can be carefully cleaned with toothpicks. When cleaning up, in order to prevent the mistake of painting irrelevant parts, it is best to carefully stick the adhesive paper around the wound. When the wheel surface is difficult to remove stains, to choose a professional cleaning agent. The cleaning agent can usually gently and effectively remove stains, reduce the damage to the aluminum alloy surface. The hub itself exists a layer of metal protective film, so when cleaning should pay special attention not to use paint brightener or other grinding materials.

4, finish the tip of the brush, paint the damaged place of the wheel hub, and then paint dry, in the painted slightly convex, easy to observe the owner.

5, to wait for the modification paint to completely dry, in the water resistant paper dipped in soapy water daub, make the surface smooth. The mixture is then used to polish and finally waxed.

6, if there is a deep wound found on the hub, and be sure to observe whether the metal surface is exposed, if you can not see the metal surface will not rust, you can concentrate on painting. Dot it with the nib and let the paint dry entirely. If you find exposed metal, you'd better replace it.

Advantages of aluminum alloy steel ring

1, energy saving and consumption reduction, excellent heat dissipation. The use of aluminum alloy steel ring can reduce the weight of the whole vehicle, reduce the rotational inertia of the wheel, improve the acceleration performance of the car, reduce the demand for braking energy, and thus reduce fuel consumption.

2, high safety. For high speed vehicles, due to tire ground friction, braking and other elevated temperature tire blowouts, braking efficiency reduction and other phenomena are common. The heat conduction coefficient of aluminum alloy is three times that of steel and iron, and it is easy to dissipate the heat generated by tires and car chassis in the air. Even in the case of lengthy distance peak speed driving or downhill continuous braking, can also make the vehicle maintain proper temperature, reducing the tire burst rate.

3, high bearing capacity. The bearing energy of aluminum alloy steel ring is 5 times that of an ordinary iron ring. It took 71,200 kilograms for the forged wheel to deform by 5 centimeters. The iron ring only bears 13,600 kilograms and is deformed by 5 centimeters. In other words, the aluminum alloy ring is five times stronger than the iron steel ring.

4, handsome appearance. The fluidity and tension of aluminum alloy are better than that of steel ring in the liquid state of elevated temperature. The late polishing and electroplating process make it able to produce a more lovely and changeable appearance. Surface anti-corrosion treatment and electrostatic powder coating also make it last as long as fresh.
