Alloy wheels provider by jjjwheel.com: At present, the performance test standards of wheel hub mainly include: Japanese JWL VIA standard; German TUV standard; American SAE Standard. German TUV standards are the most stringent, which is why European wheel brands are heavy. The following European BBS 19X8.5J cast wheel hub weighs 11.65KG, compared with other cheap cast wheel 19X8.5J hub weight is 10.68kg. Attached is the hub weight reference table, if you buy a particularly light hub , pay attention. Change HUB SAFETY FIRST!! Discover even more info on alloy wheels wholesale.
Gravity casting wheels:This is the most primitive processing method for aluminum alloy wheels, which can be formed by pouring high-temperature liquid metal into the mold and cooling it. This method is efficient and low cost, but the uniformity of each part of the manufactured wheel is poor, and the molecular density is relatively low, resulting in low strength, so it is not very suitable for high-strength use of passenger vehicles.
One is size: don’t blindly increase the hub. Some people increase the wheel hub to improve the performance of the car. Under the condition that the outer diameter of the tire remains unchanged, the large wheel hub is bound to match the wide and flat tire. The lateral swing of the car is small, and the stability is improved. pass by. However, the flatter the tire, the thinner the thickness, the worse the shock absorption performance, and the greater the sacrifice in terms of comfort. In addition, the tires are easily damaged if there are some roadblocks such as stones. Therefore, the cost of blindly increasing the hub cannot be ignored. Generally speaking, it is most appropriate to increase one or two sizes according to the size of the original wheel hub.
Since pure electric vehicles do not need an engine, the design styles of the front hoods of pure electric vehicles can be diversified, and are generally refined and sharp. The design style of “rocket front” is full of sports, and it is very windy on the road. The functional configuration of pure electric vehicles Its strengths, various types of assisted safe driving, are very popular with novice drivers. Now many first-tier cities are gradually implementing limited numbers and licenses. Many people have money to buy cars, but the number 1 license is hard to get, but the green license is not affected. Electric hybrid models, which are the only choice for car owners in many restricted areas.
The characteristics of high thermal conductivity of aluminum alloy wheels are extremely beneficial to the heat dissipation effect of the car tires due to high-speed driving, so that they are better than steel under the same conditions. It reduces the possibility of hot tires during long-distance high-speed driving, and significantly improves the safety performance of high-speed driving. It is easier to realize the “tubeless” of modern wheels. For a tubeless wheel, the original rubber inner tube is directly replaced by an aluminum rim. If a “puncture object” such as a nail is inserted into the outer wheel while driving, as long as it is not pulled out, it will not be removed. There will be an accident that the car rolls over due to a sudden flat tire like a tire with a tube. After a tubeless wheel encounters a “puncture object”, it can generally last for at least an hour or even longer, which is particularly important for the safety of cars driving on the highway.
