Let's look at the comprehensive analysis of the normal semi trailer and the drawbar trailer!

First, no matter the normal semi trailer or draw bar trailer, it alll need the tractor truck head to pull to do transportation. The two kinds of trailer traction hook position is different, the semi trailer why it called "semi" trailer, because almost half the trailer body will connect with the tractor truck head to finished production. It use the Kin Pin to link the tractor truck.  The drawbar trailer is connected to the main truck by a tractor hook, at the front of the full stake trailer, has a two meters length drawbar, it has a hook use it to link with the tractor truck head. But the nomal semi trailer use the kin pin under the trailer to link the horse truck.

Second aspect, that is nomal semi trailer and draw bar support the weight is different, that is very esay to understand and you also can refer the picture to help you to understand, if use the tractor truck head to pull the semi trailer, when the kin pin link with the horse truck and load the goods on the trailer, the tractor truck head also need to support some weight from the normal semi trailer, and when it start, due to the pulling power, the tractor truck head also support some pulling weight, but this proportion is generally not too large, the main weight is still on the central axle. However, the drawbar trailer only bears the horizontal action from the trailer, without bearing the vertical weight of the drawbar trailer. This is also a difference between drawbar trailer and normal semi trailer.

Thirst aspect, The drawbar trailer front axle with steering instability driving trouble reversing

The drawbar trailer is mainly composed of carriage, axle, bogie and traction device, in which the front axle and bogie and traction device are combined as a whole, which can be turned along with the direction of the tractor. In addition, the traction device can move up and down, and because of this, the tractor only plays the role of traction, does not bear the weight of the trailer, so the trailer can not rely on the tractor firmly "stand" on the road. The downside is obvious. It's very troublesome to reverse. The driving skill of the driver is very strictly, even more difficult than semi reversing several orders of magnitude. However, the number of drawbar trailer is very rare now. with the improvement of road facilities and the development of expressways, the problem of poor running stability of drawbar trailer has gradually become prominent. Eventually, it was banned from the highway. Now, in addition to the very individual areas of Inner Mongolia can be seen, other areas have basically disappeared.

The drawer trailer is more flexible to turning the direction, at the front of it, has the turning system, it is very convenient. Although the semi trailer and drawebar trailer is very much like, But actually complete different. First of all, the axles is concentrated in the middle of the trailer, second, the tra ction device does not move up and down. Because of this, parts of the weight  of the normal semi trailer must be borne by the tractor, Once you leave the tractor, the trailer will lose its center of gravity on the road. Overall,  the full stake semi trailer is more easily  to reverse than to fully mount. The normal semi trailer has advantage in driving stability that the drawbar trailer can not match, and it can legally drive at the high speed.
