With the continuous improvement of domestic air pollution control intensity in recent years, heavy diesel vehicles have gradually become the focus of environmental protection departments, especially in the field of passenger vehicles, the coverage of new energy is more and more extensive, almost every brand involved in the research and development of new energy models, heavy diesel vehicles have also begun to develop towards the direction of electric drive.

In recent years, the national emphasis on environmental protection has been increasing, and the new energy of vehicles has gradually become a trend, especially in the field of passenger cars. Almost all major brands have launched new energy models. As the international fuel price continues to rise, many heavy vehicles also began to enter the field of new energy.At present, new energy heavy vehicles are more common in the market, mainly including electric dump trucks, electric trucks, electric tractors, electric special vehicles, electric sanitation vehicles and so on.

In recent years, with the continuous improvement of domestic economic development level, relevant departments pay more and more attention to environmental pollution. In this environment, many car companies have launched new products that are more environmentally friendly, such as electric cars and gas vehicles. However, transportation commercial vehicles such as semi-trailers mainly run long distances and have high requirements for endurance capacity and charging places, so it is difficult to achieve comprehensive electrification.

In recent years, the country's attention to environmental protection has been increasing, and the new energy of vehicles has gradually become a trend, especially in the field of passenger cars, almost all major brands have launched new energy models. With the rising international fuel prices, many commercial vehicles have also begun to enter the field of new energy.

In recent years, the state has paid more and more attention to environmental protection, and the promotion of new energy vehicles has also been greatly improved. From purchase incentives to financial subsidies, to the continuous opening of the right of way, new energy trucks have gradually emerged and become the new darling of urban distribution transportation.

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.

Axle is one of the core components on the rear axle of semi-trailer, and the strength of axle is directly related to the load-bearing capacity of trailer axle. For the axle, the performance of the axle head is crucial.The axle head is the key part of the axle connecting wheel hub, brake drum, bearing and other wheel end components, the performance of the subsequent hub assembly is stable, to a large extent depends on the strength, toughness and accuracy of the axle head.

Wheelbase refers to the straight-line distance between two adjacent wheels on the same side of the car, generally the distance from the center of the front axle to the center of the rear axle. Semi-trailer wheelbase is the distance between the front and rear axle of the semi-trailer.Wheelbase is a very important parameter of semi-trailer, which determines the center of gravity position and space of semi-trailer, and is closely related to the performance of semi-trailer.

As a typical support axle, the trailer axle plays an important role in the fields of load bearing, braking, driving and even auxiliary shock absorption. In general, the trailer rear axle can be divided into two categories: disc type and drum type, and the subdivision can cover low flat trailer axles, three-line six-axles, eccentric trailer axles, special trailer axles, and so on. Today, we focus on low flatbed trailer axles.1.

The axle bears the heavy load, braking, damping and maintaining the stability of the vehicle, which is closely related to the attendance rate of the trailer, the quality of cargo transportation and the operating income.
