The tractor is a general large truck or semi-trailer that is pulled by tools between the front of the car and the trunk, that is, the front of the car can be pulled away from the original box and other boxes, and the box can also be pulled by other heads of the car from the original head. The front of the car with the driving capacity in front is called the tractor, and the car without the traction driving ability in the back is called the trailer, and the trailer is dragged by the tractor. There are two ways to connect the tractor and the trailer: the first is that the front half of the trailer is on the traction saddle above the rear section of the tractor, and the bridge behind the tractor bears a part of the weight of the trailer, which is the semi-trailer; The second is that the front end of the trailer is connected to the rear end of the tractor, and the tractor only provides forward pull, dragging the trailer away, but does not bear the downward weight of the trailer, which is the full trailer.
Product Description
According to the different degrees of freedom, there are single degrees of freedom and double degrees of freedom. Single-degree-of-freedom traction seat is also known as single-shaft traction seat. It can only do a longitudinal tilt of about 80. This type of traction seat has high driving stability, and is suitable for high-speed, light-load and high-center of gravity semi-trailers driving on good road surfaces. The disadvantage is that the frame is subjected to more torque because it cannot swing laterally. Dual-degree-of-freedom traction seat is also known as dual-shaft traction seat. It can do lateral and longitudinal oscillation, which can protect the frame of the heavy-duty transport tractor in different road environments. Generally, the double-axle traction seat is much higher than the single-axle type due to its height, and the lateral stability is not good in the process of high-speed driving and turning, so this type of traction seat is rarely used in ordinary road transportation.
