As a new auxiliary braking system, hydraulic retarder is widely used in freight vehicles which often travel to and from mountainous areas. The working principle of the hydraulic retarder is to convert the kinetic energy of the vehicle into heat energy trailer axle and then dissipate heat through the cooling system of the engine to achieve constant speed or deceleration of the vehicle.Like other vehicle components, the hydraulic retarder also needs to be regularly maintained and maintained, so as to ensure its stable and good operation, mainly including the following aspects:1.

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.

Semi-trailer is a kind of vehicle that is widely used in the logistics transportation industry at present. Because of its high transportation efficiency, relatively low transportation cost and less fuel consumption than ordinary freight vehicles, it is widely used. Under different transportation needs, the type, axle number and number of tires of semi-trailer are not the same.

Powder tank car, also known as powder material transport vehicle, refers to the shipment of cement, pulverized coal, stone powder, flour, chemical powder and other particle diameter is not greater than 0.1mm bulk dry material special vehicle, generally widely used in industry, agriculture, commercial, power plant, construction and other industries, belongs to a special model.From the perspective of structure, powder tank cars are generally horizontal, such as horizontal single warehouse, horizontal double warehouse and horizontal three warehouse, which are mainly single warehouse and double wa

In recent years, the development scale of cold chain transport is getting larger and larger. Many industries, such as catering, fresh food, medicine and so on, need cold chain transport to support, so the cold chain transport market is also continuing to improve. However, about what is "cold chain transportation", many people are not very clear, or think that as long as the transport of goods is cold chain transport.In fact, if strictly speaking, refrigerated transport and cold chain transport or there is a certain difference.By definition:1.

Just entering the dog days, many cities across the country seem to have turned on the "stove" mode, and the scorching summer has also caused a severe test for the use of vehicles.

8X4 trucks have always been the main force of transportation in the freight market. They have good stability, strong loading capacity, and can pull a lot of goods. They are "all in size" for goods, especially in the transportation of short- and medium-distance materials such as green transportation, less-than-truckload, and cold-chain transportation. It plays an extremely important role.The so-called "8X4" means that the total number of wheels of the vehicle is 8 groups, of which there are 4 groups of driving wheels.

Less-than-carload transport refers to the mode of transport when the weight or volume of a batch of goods is less than one car and cannot meet the conditions of vehicle transport, and other batches or even hundreds of batches of goods share a truck trailer axles.As far as the mode of transport is concerned, less-load cargo transport is divided into three kinds: road transport, railway transport and air transport, of which road transport has become the main mode of transport of less-load cargo by virtue of its flexible and convenient characteristics.Common types of less-than-carload goods:By de

Steel coil, also known as coil steel, its high strength, good toughness, very wide range of uses, from the general engineering structure to the manufacture of automobiles, Bridges, ships, etc., are inseparable from it. However, moving steel coils from the factory to various demand points is not an easy task. According to the old saying in the freight industry: kill not pull steel coil, starve not pull green tong. So why is the steel coil so frightening to trailer owners?This is because the risk of transporting steel coils is far greater than that of ordinary goods.

The hydraulic retarder works as we all know, just like a reversed water pump, which is installed at the end of the gearbox. At present, the loading volume is relatively large ZF, Voith, Scania independent research and development, etc., the domestic is Fast.
