The main differences between middle axle trailer and full trailer are:
1. Axle position:
The axle of the middle axle trailer is located in the center of gravity of the body, which can not support its own weight independently when it leaves the tractor.
The axles of the full trailer are located at the front and rear ends of the body and can stand smoothly even without the support of the tractor.
2. Traction device:
The traction device of the middle axle trailer cannot move up and down;
the full trailer traction device can swing up and down as well as left and right.
3. Composition Structure:
The middle axle trailer is mainly composed of carriage, axle and traction device, without bogie;
the full trailer is composed of carriage, axle, bogie and traction device, which can be turned along with the driving direction of the tractor.
4. Connection position:
The traction hook of the middle axle trailer connected with the main vehicle is located under the frame and indirectly connected with the frame;
the full trailer is connected to the main car by a traction hook mounted on the frame of the main car.
Full-trailer used to occupy a place in the freight market, but later, due to driving difficulty and safety problems, gradually replaced by semi-trailers. Mention the trailer, numerous elderly drivers still remember the difficulty of reversing. Since the front axle of the full trailer has a steering function, it is equivalent to two independent steering systems including the steering of the main car, so it is easy to lock yourself when reversing carelessly. This point is better on the middle axle trailer, because it is better tracking performance, reverse the tractor as steering wheel, slow back is easy to use.
The middle axle trailer is the full trailer changed its name
Speaking of mid-axle trailer, it is a rising star among freight vehicles. GB1589 newly added the middle axle trailer to this model. Some owners are optimistic about its advantages in the length limit, but as a legal "green plate" model, although the development prospect of the middle axle trailer is considerable, has not raised too much movement in the market.
The so-called middle axle trailer, broadly speaking, is the carriage of the axle installed in the middle of the trailer. This is especially true when compared to a semi-trailer:
Top semi trailer manufacturers claimed A tow a hanging, traction device is fixed, the main car is responsible for traction, trailer is responsible for cargo, and does not have the function of driving or steering. GB1589 will be in the middle of the trailer and is divided into two kinds: the middle of the axle vehicle transport train and the middle of the axle truck train, wherein the middle of the axle vehicle transport train is generally the common car transport car. The middle of the axle truck train is the van, used for general cargo transport.
Some elderly drivers think that the middle axle trailer is particularly tall like the full trailer, that the so-called middle axle trailer is the full trailer for a name "resurfacing", in fact, such a view is not accurate. Because the middle axle trailer exclusively belongs to an independent model between the full trailer and the semi trailer.
