Three-line six-axis, also known as first-line three-axis, is the only type of car that can comply with the regulations and can be on the high speed. Generally, the transport weight can reach about 80 tons. If it is the four-line eight-axis, five-line ten-axis and other models, the transport weight is higher, which can be up to hundreds or even hundreds of tons.
Such a model for axle and axle bearing performance, robustness, bending and torsional resistance and production technology and technology put forward higher requirements.
What does a three-line six-axle axle look like? Different from the ordinary axle, the design of the three-line six-axle axle is generally a group of three axle, which are arranged on a vertical axis successively, as shown in the figure below:
A three-line six-axle semi-trailer often requires two sets of such axles, mounted side by side, as shown in this typical three-line six-axle semi-trailer:
How to see how many lines and axles is the semi trailer?
One may ask: with so many wheels installed together, how can you tell how many lines and axles are there?
In fact, the method is also very simple. Take the top three-line six-axis semi-trailer for example. From the side, the semi-trailer has three rows of axles in total, which is called "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 axles"; 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.
Features of three-line six-axle axle
Many wheels and small wheels are the main characteristics of three-line six-axis.
In fact, strictly speaking, the three-line six-axis is a kind of low flat plate model. In the design, it continues the advantages of low flat plate vehicle, such as low center of gravity, convenient loading and unloading, stable driving, and strong passability of high-limit road sections.
A high number of tires to a certain extent increases the contact area between the wheel and the road surface, reduces the pressure on each tire surface, and can play a certain protective role on the road surface.
The application field of three-line six-axle axle
Three-line six-axle axle is mainly used in the transportation of large goods on the low flat semi-trailer, according to the weight of the transport of goods, three-line six-axle, four-line eight-axle, five-line 10-axle, six-line 12-axle and so on, or from the basis of the three-line six-axle to enhance.
For example, Qilu reported that the "world's first ring" shipped from Jinan to Weifang Port on August 9 was a special large piece that could not be disassembled. At that time, the flatbed car behind the tractor was designed with a total of 96 wheels. Seen 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 axle, a row of three axles installed in parallel, about equal to the ordinary eight lines and 16 axles on the basis of a row of eight lines and 16 axles, a total of eight lines and 24 axles.
The three-line six-axle axle manufactured by Hongkai Mechanical parts has 60 tons, 80 tons, 100 tons of various sizes can be customized.
