Excuse me, why is truck wheel hub different from front and rear tires?
Ordinary cars wheels less considered in appearance, good heat dissipation is one of the basic requirements, the basic use of the craft paint processing, which is to spray and then roasted, the cost is relatively economical and beautiful colors, keep for a long time, even if the vehicle is scrapped, hub color remains unchanged. Many popular models are the hub surface paint treatment process, such as Santana 2000, Natsuri Toshiya, the pride of the times, Lioncel or Honda odyssey. Some fashionable and dynamic color wheels also use paint technology. This kind of wheel hub is moderate in price and complete in specifications.
But at present, the production of a wide rim of the wheel, 22.5X11.75 22.5X14 this initiative to solve the unilateral double wheel installation, cost savings.Wheel hub is also called wheel rim. According to the characteristics and requirements of different types of vehicles, the wheel surface treatment process will also be taken in different ways, which can be roughly divided into paint and electricityThere are two kinds of wheel hub plating.
The installation method of its purpose, to increase the load, the front wheel is a guide wheel, bearing the full weight of the 1/10 so a unilateral hub, and are behind the wheel load, for example: the 22.5X8.25 hub as an example, the single load of 4 tons, the trailer is behind the three axis 12 the hub can be 48 tons. If you want to load 48 tons of weight, and trailers unilateral installation of a single wheel hub, you need 6 axes, in terms of cost, manufacturers abacus very well.
The car rear wheel load is relatively large, so each rear wheel are two tires are fixed together, for the convenience of installation at the same time in order to accommodate the brake components, the tire designed into a concave shape, as long as a few simple screw screw can then two tires and tire together, all this is for the convenience of design.
The hub is the same, concavo convex, just different mounting positions, if the front wheel is a single pack, the convex side on the outside, the rear wheel two together, the convex face convex installation, the outside nature is concave.
