The owner is too bold. Have you ever seen the tire bolts tighten only half?

Since the launch of the 921 Ultra New Deal last year, the weight reduction of models has become the key to making more profits, especially for coal transportation, which is very sensitive to its own weight. In order to reduce weight, aluminum alloy wheels quickly became the preferred accessory for many card members. Because the aluminum alloy wheels are about 25 kg lighter than the steel wheels, the entire vehicle can be replaced, which can reduce the weight of about half a ton, which is very impressive.

The weight-reducing effect of aluminum alloy wheels is impeccable, but it cannot be installed casually. If it is improperly installed, it will leave considerable security risks. A few days ago, I saw a full-car friend who had used aluminum alloy wheels in Quzhou, Hebei Province. The way it was installed surprised me with a cold sweat. The bolts holding the aluminum alloy wheels were only half way! At first I thought it was just a problem with this position, but after observing a circle around the car, I found that the car had no problems with the installation of the aluminum wheels of the two steering axles. All other positions, including the trailer axle, were This extremely dangerous installation method is used.

Why does this card friend adopt this inconsistent method of installing aluminum alloy wheels? In fact, the reason is simple. This car was originally made of ordinary steel wheels. Aluminum wheels are retrofitted. The steel wheels used in the tire bolts and aluminum wheels are completely different.

Because the thickness of the end face of the aluminum alloy wheel is very thick, reaching 25 mm, and the ordinary steel wheel thickness is only about half of the aluminum alloy wheel. When an ordinary steel wheel axle is used to replace the aluminum alloy wheel, the length of the bolt will inevitably be insufficient, and bolts for the aluminum alloy wheel must be replaced in order to be used normally.

This Luzhou card friend is guilty of this extremely low-level error. Instead of replacing the bolts when replacing aluminum alloy wheels, the aluminum alloy wheels are forcibly installed using ordinary bolts. This is very dangerous, because the working load of the tire bolt is very large, even if it is a normal installation, it is easy to get loose, breakage and other accidents, not to mention the installation of this method.

In addition, this vehicle is a coal truck, which has a relatively large load and there is a high probability of a tire falling accident when it is on the road. It is an extremely dangerous thing for yourself and others.

It is undeniable that aluminum alloy wheels are definitely the future trend. However, judging from the current state, many users are obviously not ready to fully switch aluminum alloy wheels. This kind of eye-catching and serious threat to traffic safety will continue to emerge.
