Since the introduction of GB7258-2017, the demand for disc axle in the domestic market has been rising. According to the regulations, since January 2019, the new semi-trailer for the transport of dangerous goods must use disc brake; From January 2020, three-axle rail-plate and barrel-type semi-trailers will also be equipped with disc brakes.Now three years have passed, more and more vehicles have been installed disc brake, can be used to drum brake owners, the daily application of disc brake there are many different, today we will take a simple inventory together.1.

Disc brake trailer axle, also called disc axle, because of its brake metal block shape is disk/dish named.

With the prevalence of lightweight trends in the freight industry, disc brake axles are becoming more and more popular among car owners. The disc brake bridge does not have a 360-degree wrapped brake drum, and the brake transmission components have also been optimized, so its own weight has obvious advantages.After the introduction of GB7258-2017, it is required that three-axle fences and three-axle grille semi-trailers must be installed with disc brake bridges and air suspension, otherwise it will affect the registration of vehicles.

As far as the most approved trailer axle on the market goes, disc axle goes. Since the introduction and implementation of the GB7258-2017 National Standard for Vehicle Operation Safety Technical conditions, the three-axle axle and the grille semi-axle have been required to install disc axle axle and air suspension, which, coupled with the gradual prevalence of the lightweight trend in the trailer industry, makes more and more owners turn their attention to Disc Axle.Disc trailer axle is not a new product, but it has been applied more to passenger vehicles in the past.

Many owners question whether it is necessary to force the installation of all trailer disc axle on the triaxial fence plate and triaxial warehouse grid semi-trailer.Objectively speaking, in the total quantity of commercial vehicles in China, three-axle railboard and three-axle warehouse grid semi-trailer account for a relatively high proportion, and the goods transported by them are generally low value-added products.

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 therma

Semi-trailers are the main force in the domestic transportation market, especially in long-distance cargo transportation, semi-trailers almost dominate the world. The axle of a semi-trailer is generally installed behind the center of gravity of the vehicle, so it cannot maintain the balance of the body independently.

A semi-trailer is a trailer whose axle is placed behind the center of gravity of the vehicle and is equipped with a coupling device that can transmit horizontal and vertical forces to the tractor. drive. The load of the semi-trailer needs to be borne by the semi-trailer and the main vehicle together, and it needs trailer axle to be balanced with the help of outriggers after being separated from the tractor.Common semi-trailer classification:1.
