trailer booster axle-manufacture,factory,supplier from China

Trailer axle is one of the power core assembly of semi-trailer, its main role is to carry the body weight, followed by driving and braking, to maintain the normal running of the vehicle on the road. It can be said that the safety and reliability of a trailer largely depend on the quality of its axles.With the continuous development of the domestic transportation industry, the trailer axle industry chain is becoming more and more perfect.

The central axle trailer is a rising star among freight vehicles. GB1589 relaxes the outline size of the central axle trailer compared with the semi-trailer, and introduces the central axle road train at the same time.Central axle road train is a kind of car train, which is composed of automobiles and central axle trailers.

Since the implementation of GB1589, the car industry has suffered a very big impact. At the same time, the new standard specifically adds the provisions of the mid-axle car, which can reach 22 meters in length, compared to the articulated train can be 5 meters longer trailer axle. Therefore, in the eyes of some people, the mid-axle car is the new direction of the future car industry. In foreign countries, the middle axle car has been popular for many years.After visiting the market, many people were not interested in such vehicles.

Taking the trailer axle of Darong Group as an example, we start with raw materials. The trailer axle is selected 20Mn2 high-strength alloy seamless steel pipe with wall thickness of 11mm, and the quality test is qualified, and the production process is officially entered.1.

Due to the different road conditions and axle usage in each region, the maintenance cycle of the DARO drum trailer axle provided below is for reference only.Friction plate inspection: After the axle is driven every three months or 25,000 kilometers and after each disassembly of the hub and wheel, it is mainly to check whether the thickness of the friction plate is normal, the normal thickness of the friction plate is at least 5mm, if it is less than or close to this thickness, it is necessary to seize the time to replace the friction plate to prevent the abnormal braking of the vehicle.Brake d

When buying a trailer axle, some owners like to go to the axle factory to visit the field and see the scale and production process of the manufacturer, so as to judge the production level and quality of the manufacturer. For the trailer axle, its main role is to carry the weight of the body, so the stiffness and toughness requirements are higher.So, how does the axle factory ensure the rigidity or toughness of the axle?This also relies on the three major production processes of the axle plant: hot rolling, tempering heat treatment, and medium-frequency strengthening treatment.

With the relevant departments on the semi-trailer load more and more strict supervision, lightweight gradually become the industry's focus. Under the same load limit, the lighter the weight of the trailer itself, the more goods it can load. Therefore, many owners also prefer lightweight trailers or trailer accessories.As we all know, the use of disc trailer axle and air bag suspension, is one of the ways of lightweight trailer. However, in the promotion process of disc axle, it has been questioned a lot.

Trailer is a type of vehicle that does not have its own driving force, and needs to be powered by a tractor to drive, from a structural point of view, it can be mainly divided into full-mounted, mid-mounted and semi-mounted, of which full-mounted and mid-mounted axles are more common.Full hangingCenter axle typesemi-hangingThe application field of trailer is very wide, warehouse, factory, port, dock, farmland, road, field, etc., almost can see their figure.Due to the different working conditions, the functions of the trailer are also very different.

With the continuous strengthening of governance in all aspects of highway transport industry, the word "middle axle trailer" is also appearing more and more frequently in the line of sight of owners, and even in GB1589, there are new middle axle trailer models. Some owners may ask: what kind of vehicle is the middle axle trailer?In popular terms, the middle axle trailer is the trailer whose axle is located in the center of the vehicle's center of gravity.

The trailer axle is one of the key components on the vehicle chassis, which is related to the performance of the vehicle body load-bearing, auxiliary braking and shock absorption. There are many types of trailer axles, such as drive axles, steering axles, drive steering axles, and support axles. From the structural form, they can be divided into two types: integral trailer axles and disconnected trailer axles.The integral trailer axle is easier to understand. Like the trucks we usually see, most of them use the integral trailer axle.
