In our daily lives, we occasionally see or hear the word "tractor-trailer." What is a tractor-trailer? To be exact, there are two explanations for "tractor-trailer" in general:
One is a noun, refers to a freight vehicle. This vehicle itself has no driving force, the main role is load-bearing, need to pull with the traction of the front of the vehicle, can also be called a trailer, such as we frequently say trailer or semi-trailer.
The other is a verb that means a tractor-trailer is on the road, as in the traffic law, "No tractor-trailer is allowed during the internship period."
The trailer is a relatively widely used model in the logistics transportation industry. Especially with the continuous development of the transportation industry in China, Semi Trailer price is gradually being favored by more and more logistics companies due to its characteristics such as large transportation capacity and extensive transportation of goods.
on the other hand, our country's road transportation market is huge, but with varied terrain and climate conditions, the traffic situation is more complex, and related standards and regulations are reliable for trailer line, attendance, transport efficiency, put forward the higher request. This also let more and more trailer accessories manufacturers begin to authors efficiency direction.
As one of the key components of the trailer, can the axle also achieve cost reduction and efficiency?
The answer is yes, just like the motor vehicle operation safety technical conditions GB7258-2017 standard issued last year, requires the use of disc brakes and air bag suspension for the installation of three-axis bar plate and grille semi-trailer, which is really a means of reducing cost and increasing efficiency.
Axle design lightweight within the specified range to achieve multiple cargo
In the design and production of trailers and tractors, lightweight has always been an essential means to reduce costs and increase efficiency. After all, only when the weight of the vehicle is reduced, additional weight space can be left to load goods within the prescribed range.
According to the relevant data, the axle weight of a three-axle trailer is nearly more than 20% of the total weight of the trailer, so for the trailer to reduce the weight, the realization of axle and axle lightweight is extremely significant.
But, compared with other parts of lightweight design, axle reduce some essential more difficult, because the bridge itself is a bearing part, realize its own weight at the same time also needs to ensure that its bearing performance, otherwise it may do more harm than good, not only can't save fuel consumption, increase efficiency, and instead to cause a decline in load, reduce the transportation revenue. This has put forward fairly high requirements on the raw materials, production technology and production technology of the axle.
