Nowadays, the application of hydraulic retarder in commercial vehicles is more and more popular, as an auxiliary brake device, and even was once called the vehicle safety "artifact".The working principle of the hydraulic retarder is to convert the kinetic energy of the vehicle into heat energy and then heat dissipation through the cooling system of the engine.

Because of its excellent braking performance and good heat dissipation effect, the disc axle of semi-trailer has gradually become the first choice in many transportation scenarios.

Owners who have run through the transportation understand that more brakes are used on the trailer to count drum braking, but when buying a car, you can always hear the sales staff introduce the design of the "front disc and back drum".The so-called "front disc and back drum" refers to the disc brake used by the front wheel of the vehicle and the drum brake used by the rear wheel.In fact, in 2019, the Ministry of Transport issued the relevant standards for tractors and trailers, which made clear instructions on the restrictions on the installation of braking devices on trac

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.

In all the configurations of the vehicle, the brake system is the most basic safety guarantee, once the brake system fails, other high-end configurations can only become empty talk. There is a saying that the performance of a car is not judged by how fast it can run, but by whether it can stop smoothly and safely no matter how fast it runs.There are many kinds of vehicle braking methods, in addition to the gas brake, oil brake, and line brake, air brake, exhaust brake, electromagnetic brake and so on.

In recent years, freight levels in the freight industry have continued to fall, and the income of car owners is significantly less than before. How much did the freight drop?A car owner in Guangdong shared the operating costs of his nearly three years of running transportation, taking his 4.2 meter light truck as an example, the attendance rate is 65%, and the average day can receive 1.4 orders.

Recently, a number of typhoons have arrived in China, with strong winds and a wide range of effects.

When driving a semi-trailer in winter, the following points should be noted to ensure driving safety: Inspection and maintenance before driving: In winter, especially on icy and snowy roads, the ABS or EBS system of a semi-trailer may malfunction,which may cause the vehicle to slip or lose control during emergency braking. Therefore, it is necessary to check whether these systems are working properly before traveling to ensure that there are no malfunctions.‌1 Inspection of tires and brake systems: Low temperatures in winter may affect the tires and brake systems.

For semi-trailer owners, the main source of profit is freight, the longer the bucket, or the higher the fence, the more goods can be loaded naturally. Many owners are ready to change the car to consider how to make the vehicle as long as possible, but afraid to buy after the card. So, under the current standard, the length of the semi trailer can do how many meters?According to GB 1589-2016 Limits for external Dimensions, axle Load and Mass of Automobiles, Trailers and Automobile Trains:1.

Carrying capacity: The axle must be able to withstand the total weight of vehicles and goods, so its carrying capacity is the primary consideration.Reliability: The reliability of the axle is directly related to driving safety, so people usually pay attention to the quality and brand reputation of the axle.Durability: Due to the frequent use of semi-trailers in harsh road conditions, the durability of the axle is also an important consideration.Maintenance cost: A low maintenance cost axle is crucial for reducing operating costs and improving economic efficiency.Technical level: With the devel
