Product recommendation | DARO three-line six-axle axle

Three-line six-axis, commonly known as "crawling all over the ground", is currently the only class of compliance on the household, can be on the high-speed "hundred-ton king" model, the general transport weight can reach about 80t, if it is four-line eight-axis, five-line ten-axis and other models, the weight of transport is higher, can be as high as hundreds or even hundreds of tons.

Such a model for the trailer axle bearing performance, robustness, bending and torsional resistance and production technology and technology put forward higher requirements.

1. What does the three-line six-axle trailer axle look like?

Different from ordinary axles, the three-line six-axis is generally a group of three axles in design, arranged in turn on a vertical axis, as shown in the following figure:

A three-line six-axis semi-trailer often requires two sets of such axles, installed side by side, as follows for this typical three-line six-axis semi-trailer:

2, how to see how many lines and axes is the semi-trailer?

Some people may ask: with so many wheels installed together, how can we tell how many lines and axes are there?

In fact, the method is also very simple, take the above three-line six-axis semi-trailer for example, from the side number, the semi-trailer is a total of three rows of axles, this is the "three-line";

From the back, a row of axles are installed in parallel with two axles, a total of six axles, this is the "six axes";

Two tires are installed at each end of an axle, that is, one axle is four tires, a row of axles is eight tires, and three rows of axles is twenty-four tires.

3, the characteristics of the three-line six-axis trailer axle

Many wheels and small wheels are the main characteristics of three-wire six-axis.

In fact, strictly speaking, the three-line six-axis is a kind of low flat plate model, which continues the advantages of low flat plate vehicle in design, such as low center of gravity, convenient loading and unloading, stable driving, and strong passability of high-limit road sections.

The high number of tires increases the contact area between the wheel and the road surface to a certain extent, reduces the pressure on each tire surface, and can play a certain protective role on the road surface.

4. Application field of three-line six-axis trailer axle

Three-line six-axis is mainly used in the special transport of large goods on the low flat semi-trailer, according to the weight of the transport of goods, three-line six-axis, four-line eight-axis, five-line ten-axis, six-line twelve-axis and so on, or from the three-line six-axis on the basis of enhancement.

For example, the "world's first ring" transported from Jinan to Weifang Port some time ago belongs to special large-sized transportation, when the flatbed car behind the tractor was designed with a total of 96 wheels. From the side, this car is designed with eight rows of axles, so that a row of twelve wheels, according to the calculation of four wheels of one shaft, a row of three axles are installed in parallel, which is about equal to adding a row of eight lines and sixteen axles on the basis of the ordinary eight lines and sixteen axles, a total of eight lines and twenty-four axles.

It is worth noting that although the three-line six-axis model can legally drive on the road, but at present only the three-line six-axis can be handled on the household, the remaining models need to apply for a temporary license, the validity period is usually about one month, and it needs to be reissued before the expiration.

In addition, some areas may have different provisions for the operation route and operation time of these heavy transport vehicles, and specific problems need to be analyzed.

5. DARO three-wire six-axis

At present, the rated load of DARO three-wire six-axis is 80t, the self-weight is about 3000kg, and other wheel bases can be customized according to the actual needs of customers.

Super bearing capacity - Using high-strength alloy thickened steel pipe shaft, bearing up to 80t.

Long service life - mechanically connected suspension, simple structure, improve axle strength, extend service life.

Strong and durable - the selection of high-strength, high-precision bearings, long-term low rolling resistance, more reliable performance.

The road damage is small - more axle tires, reduce the pressure on the road surface, can be on the high speed, suitable for long-distance transportation.

Bending and torsional resistance - the shaft beam is not easy to bend, and the bearing capacity is more reasonable.
