Fast braking and heat dissipation trailer axle with disc brake
Trailer axle with disc brake a subsidiary of DARO Group is specially designed for semi-trailers. The brake pads are directly exposed in the air, which makes the heat dissipation performance stronger, the thermal attenuation and water attenuation resistance stronger, and the braking more sensitive. With ABS/EBS and other brake assistance systems, the trailer will have better braking effect.

Spring Centre(mm）：900
Track(mm）：1840
Total Length OL(mm）：≈2180
Products Description
The DARO trailer axle with disc brake has a lighter weight, and the 360° brake drum is banned, which greatly improves the weight. At the same time, after the installation of the disc axle, there is no need to install the water sprinkling device, which can further increase the load of the vehicle. In addition, the brake pads of the disc trailer axle are directly outside, you can see the brake pads or other structures very intuitively, do not need to remove the axle, you can see whether you need to maintain, if you need to maintain only need to replace the brake pads, quickly, it only takes more than half an hour to complete.

Compared with drum axle, the trailer axle with disc brake are light weight, fast heat dissipation, sensitive response, and strong ability to resist thermal decay and water decay. Open wheel end design, high ventilation efficiency, fast heat dissipation, frequent continuous braking is not easy to appear thermal attenuation, through the water section of the wheel end is not easy to collect water, good water attenuation performance, after the water to step on the brake pedal several times can restore the braking performance.
Application Scenario
Application fields of trailer axle with disc brake:
1, three axis fence plate/grid vehicle: these two types of trailers are clear regulations, must be installed disc axle models, otherwise it will affect the license or road driving.
2, precision instruments/valuables transport: the particularity of this kind of goods on the vehicle and transportation process requirements are more strict, the application of disc axle can make the brake more sensitive, more stable, to avoid the goods bump or larger vibration.
3, transport of dangerous goods: dangerous chemical transport vehicles than ordinary cargo vehicles higher risk factor, the use of disc axle can reduce as much as possible due to the uneven distribution of vehicle braking force, brake heat dissipation and other factors caused by accidents.
4, green pass/flowers/fragile goods transport: This kind of goods have high requirements for goods damage, suitable for the disc brake with air suspension, both in the longitudinal efficient buffer from the road bumps, but also enhance the linear stability of the horizontal direction, so that the goods are protected in a full range.
Package & Delivery
The advantages of trailer axle with disc brake are obvious, but the disadvantages cannot be ignored:
Due to its structure, its braking strength is not as strong as the drum brake bridge, which restricts the use of the disc axle to a certain extent, and some loading mass is large or there is overload and partial load, it is not suitable for the use of the disc brake bridge.
The open wheel end leads to the brake disc, brake pads and other parts exposed, vulnerable to the impact of splashing soil, sand and stone, to a certain extent, not as resistant as the drum brake bridge, in the mud, Gobi, potholes, bumps, sand and stone fields and other environments are not suitable.
