The axle is the key component of the trailer chassis, which is directly related to the load-bearing, braking, drive transmission and other performance of the vehicle, and plays a vital role in driving safety. For a long time, most of our long-distance transportation industry has used drum braking and chose water cooling when going down a long and continuous slope. Disc brake is more used in passenger cars.

However, even with the support of the shower, the drum brake is difficult to retreat in the test of continuous long downhill. Dangerous accidents such as brake failure on long downhill occur from time to time, which highlights the importance of the braking system. Gb7258-2017 requires that the replacement of three axle trailer must be equipped with disc automatic, which is also to better ensure driving safety to a certain extent.

Many old drivers understand the reliability of disc brake. Different from the low reliability of long-time continuous braking of drum axle, the disc brake has simple structure, the braking friction surface is directly exposed in the air, and the heat dissipation is better, which can effectively avoid the phenomenon of heat recession; The brake disc bears compressive stress and has better crack resistance under continuous braking; Disc brake has no friction potential, and the braking force of left and right wheels is more average; The braking system has fast response speed and is more suitable for EBS / ABS system.

It can be seen that disc brake has irreplaceable advantages. Disc brake enables vehicles to have more reliable braking effect on mountain roads, long downhill and various complex road conditions.

The braking system and axle depend on each other. The impact of a good axle on driving safety is self-evident. In the Chinese market, the policy of replacing disc axles for trailers has been issued for only three years, and the implementation time is shorter. Although major axle manufacturers produce disc axles suitable for semi trailers, many car owners still make difficulties in making choices.

Like other products, only when it can stand the test of the market can it be called a qualified axle. Just like the axle produced by Darong group, it has more than 20 years of user experience and has been refined into a high-quality axle.

Lightweight materials and accessories are adopted, which makes the axle lighter and fully saves oil and improves efficiency.

The integrated alloy brake disc has better heat dissipation performance and fast heat conduction speed.

Simplify maintenance procedures, facilitate maintenance and improve operation efficiency.

Camber 1 ° design, more uniform friction between tire and ground.

Integrated alloy brake disc, made by special technology, is wear-resistant, crack resistant and efficient heat dissipation.

Special high-strength bearing for trailer, effectively prolonging service life.

Locally strengthened square shaft beam has large section coefficient and strong torsional and flexural capacity.

The integral heat treatment technology improves the overall mechanical performance of the axle and has good fatigue resistance and toughness.

The braking is more sensitive and stable, and it is safer to cooperate with ABS and EBS systems.
