How to adjust the brake of the disc brake trailer axle?

Disc brake shaft is a vehicle component widely used in passenger cars, relying on calipers to clamp the brake disc to produce friction to achieve braking, because the metal block used in the brake assembly is disk-like, also known as the disc trailer axle.

In recent years, with the mandatory promotion of regulations and the influence of the industry trend, the application of disc brake shaft in commercial vehicles is more and more, and gradually shine with the advantages of light weight, sensitive response, smooth braking, good heat dissipation, strong resistance to water attenuation and thermal attenuation.

For the owners who are used to the drum brake shaft, even if they are good, they still beat the load-bearing capacity of the disc brake and feel that the cargo may not be reliable.

Objectively speaking, such concerns are not unreasonable, after all, compared with the drum brake shaft, the structural design of the disc brake is indeed more "thin". Like the three-axis fence plate, the three-axis warehouse grid such as the "universal oil" type model, with the disc brake trailer axle can also pull goods as before?

In fact, you are mainly clear about the fact that the disc brake shaft is promoted not because it is good at bearing weight and can DORA goods, but because it has various advantages, it can even be said that it is because it can not pull the overload so it has been implemented by law.

Take the market coverage of the most extensive three-axis plate and grid car, although these models have high ownership, can be poor safety technology, transport of goods and more belong to low value-added products, owners in order to earn more freight often in accordance with the maximum limit of nuclear load for transport, and even directly ignore traffic regulations overload, which not only affects traffic safety, damage the road surface, It will also be detrimental to the long-term development of the transport market. Forcing its installation of disc brakes and air suspension, in addition to improving its driving safety, to a certain extent, can reduce the possibility of overload.

In addition, the disc brake shaft on the market is generally sold by tonnage, like the conventional 13t model, and the bearing range of the 13t drum brake is consistent, as long as it does not exceed this range, basically there will be no problems. Of course, the premise is that the quality of the selected disc brake shaft is strictly up to standard and cannot be shoddy. The second is the working condition problem, the disc brake shaft is suitable for use in the field of standard transport, some precision instruments, dangerous chemicals, green pass, fragile and vulnerable, valuable goods transport is also more suitable for the disc brake shaft.

So, during the use of the disc brake shaft, do you need to adjust the brake gap as often as when using the drum brake shaft? The answer is no. Because the disc brake shaft is generally equipped with a self-adjusting arm, it is usually not necessary to manually adjust. Of course, do not need to "often adjust" and do not need to adjust are two concepts, if the owner has just changed the brake component, or just finished the wheel end maintenance, it is recommended to manually adjust it, may lead to the drag brake situation.

How does the disc brake shaft adjust the brake clearance? The method is also relatively simple:

Find the gap adjuster;

Use a special wrench to tighten it in the direction of tightening, then the wheel end is not moving;

Then the bolt in the direction of the loose back to twist three, a twist will make a "da" sound, after three sounds, the brake gap is adjusted.

When choosing the disc brake shaft, remember to shop around, DARO Group specializes in the production of all kinds of trailer axles for 20 years, its disc brake shaft is made of 20Mn2 high-strength alloy seamless steel pipe, from the raw material to ensure strength, toughness and lightweight, while with a one-piece heat treatment molding technology, three-hole boring finishing, medium frequency induction treatment and other more than 10 processes. The finished products have been tested before leaving the factory to ensure that the quality is up to standard, stable and reliable.
