Speaking of the middle axle trailer, it is a rising star in freight vehicles. After GB1589 added the middle-axle trailer this model, some owners are optimistic about its advantages in the length limit, but as a regulatory "green plate" model, the development prospects of the middle-axle trailer are considerable, and it has not set off too much movement in the market.The so-called middle axle trailer is a trailer in which the axle of the carriage is installed in the middle of the carriage.

Trailer is one of the frequently used models in transportation, which plays a vital role in the field of cargo transportation. However, as a heavy transport tool, there are many problems in the practical application of trailer. Axle fire is a very common one. Open the search engine, there are many cases about "axle fire of trailer".Once the trailer axle catches fire, it often causes the tires to burn, and then the tarpaulin and cargo on the trailer will also be ignited, eventually leading to a fire in the whole vehicle.

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.

The low flat trailer axle is a typical semi-trailer support bridge, that is, we often say the rear bridge, which plays the role of bearing, braking, maintaining and so on.

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.

Therefore, many owners also prefer lightweight trailers or trailer accessories.As we all know, the use of disc trailer axle and air bag suspension, is one of the ways of lightweight trailer. However, in the promotion process of disc axle, it has been questioned a lot.
