What's the maximum distance your truck can travel in a year? For the old drivers who are often on the road, it is easy to 200,000-300,000 kilometers a year, and many card friends also joke that they are people who live on wheels.

Vehicle length is closely related to cargo load and transportation efficiency. In general, the larger the vehicle profile size, the higher the volume of goods can be transported.According to relevant regulations, the total length of tractors and semi-trailers in China shall not exceed 17.5m, and the standard length is generally 10m, 11m, 13m, 14.6m and 16m. In Europe, the regulation on the length limit of semi-trailer is similar.

To say that the current general trend of the freight industry is lightweight. Lightweight can not only increase loading capacity and improve transportation efficiency, but also reduce fuel consumption, improve energy saving and emission reduction, which coincides with the road of "cost reduction and efficiency increase" insisted by my country's logistics industry.

With the increase of the national control of overload and the implementation of the weight charge policy, the heavy semi trailer has gradually deviated from the development trend of the industry, especially after the introduction of GB1589, the carrying weight of the semi trailer has changed a lot, from the original 55t to 46-49t, in order to achieve more cargo under the premise of not overload, the vehicle lightweight is the key.The lightweight semi trailer is a product of the lightweight trend.

The wheel is an important part of the vehicle walking mechanism, which not only supports the weight of the whole vehicle, alleviates the impact of the road, but also generates driving force and braking force through the adhesion of the tire to the road surface to ensure the normal running of the vehicle.The composition structure of the wheel mainly includes the rim, the spoke, the hub and the tire. Among them, the rim, the spoke and the hub sound like the same, so that many owners do not know, today we will talk about the difference between them.1.

Large trucks refer to large vehicles used for transporting large amounts of goods, including the following types:1. Truck mounted trucks: These vehicles typically have a foldable crane arm installed at the front of the truck to lift and dump cargo from the truck. They are mainly used in construction, mining, and other industries that require a large amount of transportation and dumping of goods.2. Tractor trailers: This is a common type of freight vehicle consisting of a tractor and one or more trailers.

Since the introduction of GB7258-2017, the demand for disc axle in the domestic market has been rising. According to the regulations, since January 2019, the new semi-trailer for the transport of dangerous goods must use disc brake; From January 2020, three-axle rail-plate and barrel-type semi-trailers will also be equipped with disc brakes.Now three years have passed, more and more vehicles have been installed disc brake, can be used to drum brake owners, the daily application of disc brake there are many different, today we will take a simple inventory together.1.

With the rapid improvement of China's economic level, the transportation industry has also made great progress, especially the road transportation.

Steel wire tire and vacuum tire adapted modelsFirst of all, there are steel tires and vacuum tires, which are subdivided into a variety of trailer axle models, and different models are adapted to different models.Among them, the most common on the market are 11.00R20 steel wire tires and 12.00R22.5 vacuum tires, which are widely used in flower baskets, standard cars, roll-over dump and various types of hazardous chemical vehicles, of which 12.00R22.5 vacuum tires are equipped with good long-distance road conditions, and the pattern is mostly 3 or 4 lines.Road conditions are poor, short distanc

Exhaust gas is the exhaust gas discharged from the exhaust pipe of the vehicle during use. Under normal circumstances, the exhaust gas of the vehicle is colorless and transparent, with a little smell, when the weather is cold, the water vapor in the exhaust pipe is condensed, and the exhaust gas is white fog trailer axle.In the process of daily use of vehicles, it is inevitable that there are large or small abnormal phenomena, some of which are often manifested through exhaust gas.
