The rim, commonly known as the wheel rim, is the part around the wheel that mounts and supports the tire. Its role is mainly to connect the axle and the wheel, to bear the wheel load together with the tire, and to dissipate the heat generated by the tire.
According to the different raw materials, rims can be divided into cast iron rims, steel rims, aluminum alloy rims, magnesium alloy rims, carbon fiber composite rims, etc., of which steel and aluminum alloy are the most common, also known as "steel rims" and "aluminum rims".
Previously in the freight market, the proportion of steel rims is relatively large, but with the prevalence of lightweight trends, the aluminum rims are becoming increasingly hot. It is understood that in Europe and the United States and other developed countries, the use of aluminum ring in freight vehicles is very widespread, and to a certain extent to improve the reliability and maturity of its technology. But in the domestic market, aluminum ring in most freight models are also optional accessories, owners of its mixed reviews.
Today, Da Rong Axle will briefly talk about the respective characteristics of steel and aluminum rims, for your choice.
1, steel rims.
As the market's widest popularity of a rim, the most obvious advantage of steel rims is the price is cheap, simple production process, low cost, low cost, common truck steel rim prices are generally in the hundreds of dollars, most owners can afford.
In addition, the strength of the steel circle is generally higher than the aluminum circle, bearing capacity and impact resistance is stronger, not easy to deformation, more suitable for complex road conditions, relatively longer service life.
2, aluminum rims.
The most obvious feature of the aluminum ring is light weight, can be about half lighter than the steel ring. According to the relevant test, a semi-trailer if the whole vehicle optional aluminum ring, can be installed than the steel ring weight reduction of nearly half a ton, not only can save fuel, energy, reduce consumption, but also can be loaded more goods, so that owners get higher operating income.
In addition is the heat dissipation, aluminum heat transfer coefficient is about three times that of steel, the use of aluminum rims can improve the efficiency of heat dissipation, reduce or avoid overheating at the wheel end, which is conducive to extending the service life of tires, brake drums, brake pads and other components.
In addition, the corrosion resistance of aluminum rims is also higher than steel rims, daily maintenance is more convenient, the appearance also looks more upscale.
Through the above we can see that the aluminum ring in the advantages of a more comprehensive, but this does not mean that the aluminum ring must be better than the steel ring, after all, the choice of vehicle parts or depends on the daily use of the working conditions, leaving aside the working conditions to talk about the advantages is not desirable.
In general, the aluminum ring is more suitable for long-distance standard load transport, such as higher security requirements for the transport of dangerous chemicals, high requirements for timeliness of long-distance cold chain transport, etc.; in some need for frequent braking conditions, you can also consider using aluminum ring, because its heat dissipation performance is really better than steel ring, to a certain extent can guarantee the stability of the performance of the braking system.
The main advantage of steel rims is in the load-bearing capacity, also relatively more resistant to construction, some of the high load requirements for the transport of goods, such as gravel, wood, coal, steel, cement, or choose steel rims more appropriate.
Of course, choose which rim also need to consider the budget, the price of aluminum rims than steel rims expensive, the average single in about a thousand dollars, and the chance of damage caused by improper use is higher than steel rims, such as tires without air in the case of direct contact between the rim and the road, aluminum rims may be directly scrapped.
It is worth noting that whether it is a steel or aluminum rim, the use of the process must be well maintained and maintained, once found damaged, we must promptly repair or replace.
