Darong Group, founded in 2001, is one of the leaders of local axle enterprises in Liangshan. After years of accumulation, it has mature research and development and production experience in axle, axle, suspension, accessories and other fields. With reliable quality, professional service and fair price, it has cooperated with customers in more than 50 countries and regions such as Asia, Europe, Latin America, Middle East, Australia and Africa.

So, what kinds of axles does Darong Group have? Where does it fit in? Today I will give you a brief introduction.

Market hot - American axle

American axle is one of the first products to be introduced to the market by Darong, and it is also the most favored axle style by domestic car owners with the highest market coverage.

Compared with other types of axle, American axle has excellent load-bearing, durable and resistant, relatively simple design, common parts in the industry, relatively convenient maintenance steps, high cost performance, and can be widely used in all kinds of general cargo transportation.

The 20Mn2 high-strength seamless steel pipe is used in the bridge, which is divided into two kinds: 150×150 square pipe and φ127 round pipe. The tensile strength, yield strength, impact toughness and other trustworthy, such as sand and stone, steel coil, wood, coal and other cargo transportation can also be applied. Especially in the early years when the phenomenon of overloading in the transportation field was common, Darong American axle won the welcome of owners with its super load-bearing capacity.

Darong American axle standard bearing 13t, heavy load is divided into 14t, 15t, 16t, 20t, 25t, light weight bearing 10t, 12t, other specifications can be customized.

Long-distance standard load - German axle

Dairongde type axle is specially suitable for conditions requiring higher transportation timeliness, vehicle attendance and maintenance cycle, such as suspension, port, cold chain, green pass, express transportation and so on.

Compared with the American axle of the same tonnage, the weight is lighter, the running is more fuel efficient, the clearance between the bearing and the shaft head is more closely matched, the resistance is smaller, the stability is better, and the heat dissipation speed of the brake drum is improved, the heat decay is reduced, the high temperature resistance is more suitable for long-distance standard load transportation.

The tonnage with higher market demand is mainly concentrated in 12t, 13t, 14t, and some larger tonnage such as 16t and 18t are in less demand, which is also because the main advantages of German axle are long-term durability, fuel saving and efficiency, and the heavy-duty performance is slightly worse than that of American axle.

The representative of lightweight - disc airbag bridge

As the national standard designated axle suspension collocation method, disc brake and empty suspension in recent years in the market demand is also increasing, and gradually become dangerous chemicals, precision instruments, fragile and fragile goods transportation field of the new favorite.

As a representative of lightweight products, the design is more compact, the shaft tube adopts a high-strength steel integrated square shaft, without welding, fully avoiding material strength degradation, and with high-precision and lightweight parts, it is very suitable for the use of high-speed trailers. Through practical use cases, this set of products can provide reliable load-bearing, braking and shock absorption performance even on complex national roads, and the parts replacement cycle is up to 2 years, which is durable.

Rear axle for large truck - low flat truck bridge

Low flatbed truck bridge has a wide range of applications in the field of freight transport, such as the transportation of some large non-removable mechanical equipment, large tanks, construction equipment, power station equipment, generally choose low flatbed truck bridge.

Compared with the ordinary trailer rear axle, the wheel end size of the low flat truck bridge is smaller and the height from the ground is shorter, which can further reduce the center of gravity of the vehicle, the loading and unloading of goods is more convenient, and the driving stability has also been improved. When the vehicle transports ultra-high goods on the height limit section, the passability will be stronger.

The seamless steel pipe wall thickness selected by Darong low flat truck bridge is higher, the wheel hub, brake drum, friction plate and other accessories are also dedicated, bending, torsion and fatigue resistance, load-bearing performance is more reliable.

Special low flat plate - eccentric axle

From the appearance, the eccentric axle is very similar to the low flat truck bridge, the wheel end is small, the center of gravity is low, but the eccentric axle adds a "Z" shape structure at both ends of the shaft beam, so that the shaft beam is not in the same straight line with the hub center, which can further reduce the vehicle chassis.

Darong eccentric axle is mainly used in the field of car transport, can achieve the upper and lower two rows of loading can not be too high, the vehicle runs more smoothly, the turning radius is more flexible, at the same time, the lower chassis can further reduce the wind resistance, reduce power loss, so that the performance of the vehicle can be fully played.

Of course, other transportation areas with low center of gravity requirements for vehicles can also choose eccentric axle, but the lower chassis often means that the requirements for road conditions are also higher, and it is not suitable for some potholes on uneven roads.

Special transport special - three lines six axes

Three-line six-axle axle is mainly used for large transport, this kind of cargo volume weight is large, generally not removable.

Three-line six-axis axle is a multi-axis axle, its main characteristics are more wheels, small wheel end, can reduce the average pressure of the contact surface, reduce the damage of tires and road surface, super load can comply with the high speed, bearing strength according to the number of axes gradually increased, such as three-line six-axis, four-line eight-axis, five-line ten-axis and so on.

Darong three-line six-axle axle rated load 80t, using high-strength alloy thickened steel pipe to create the shaft body, with high-strength, high-precision bearings, mechanical connection suspension, structural design is relatively simple, more reasonable bearing, improve axle strength, extend service life.

Small tonnage trailer bridge custom series

Compared with the semi-trailer, the application field of light trailers is more extensive, covering industrial production, agricultural and animal husbandry operations, short-distance transportation, self-driving travel, etc., at the same time, an application field is divided into a variety of functions, such as agricultural trailers can be subdivided into equipment transportation, food transportation, forage pickup, fertilizer watering, etc., the specifications and parameters of the axle are not the same. If you want to meet the needs of customers, you can only go through customization.

Darong light trailer bridge tonnage range is concentrated in 3T-9T, from design, research and development, material selection, production, accessories matching, finished product assembly, after-sales support, to provide 360° nanny customized services, lightweight and compact structure, full energy saving and consumption reduction, can perfectly match the needs of customers.

Electromagnetic brake axle

Since the introduction of C6 driver's license, the market demand for caravan trailers is also rising. For the use of caravan trailers, Darong has launched a series of electromagnetic bridge products with faster braking response, more stable effect, and wide braking force adjustment range, which can flexibly adapt to the braking system of different vehicles in front of them or the braking habits of different drivers. It can also automatically increase or decrease the braking force according to the slope of the road, and the safety performance is high.
