How many axles does a semi-trailer have? Which axle is better for a semi-trailer?
Publish Time: 2024-09-10
In recent years, China's logistics and transportation industry has gradually developed in the direction of intensive and efficient development, and logistics companies have an urgent need for efficient vehicles. Compared with "monotype" vehicles, the transportation efficiency of semi-trailers can be increased by about 30%-50%, while the transportation cost is reduced by about 30%-40%. Therefore, semi-trailers are increasingly used in cargo transportation.
So, how many axles does the semi-trailer we often talk about have?The so-called "semi-trailer" is relative to the "full trailer", which refers to a trailer with an axle placed behind the center of gravity of the vehicle (when the vehicle is evenly loaded) and equipped with a coupling device that can transmit horizontal and vertical forces to the tractor. To put it simply, a semi-trailer is a vehicle that needs the front of the vehicle to bear part of the weight of the trailer, as shown in the figure below:
A full trailer can be completely borne by the trailer itself, connected to the front of the vehicle with a hook, and only needs to be towed by the front of the vehicle, as shown in the figure below:
Generally speaking, a semi-trailer refers to a three-axle semi-trailer, which can be further classified into dump semi-trailers, low-bed semi-trailers, warehouse-type semi-trailers, container semi-trailers, tank semi-trailers, van semi-trailers, oil transport semi-trailers, light semi-trailers, vehicle transport semi-trailers, powder and granular material transport semi-trailers, chemical liquid transport semi-trailers, heavy low-bed semi-trailers, board-type semi-trailers, gooseneck semi-trailers, skeleton container semi-trailers, 17.5-meter low-bed semi-trailers, bulk cement tank transport semi-trailers, etc.For semi-trailers, safety and reliability are crucial, which are directly related to transportation safety and transportation economic benefits. The performance of a semi-trailer depends largely on its chassis components, that is, the performance of the axle system, especially the braking system of the vehicle is also dependent on the axle, and its importance needs no further explanation. Therefore, choosing the right axle means choosing the right safety and economic benefits.However, there are many kinds of products on the axle market, and many car owners are troubled when facing numerous brands. How to choose? Which one is better?In fact, like other consumer products, a good brand is one that can withstand the test of the market. TND axle is a leader in the domestic axle market.
