[Xiagong Chu Sheng original] Some time ago, some netizens proposed the question: "After double-guided and dual-drive rear trailers are common?" This is a time when netizens have many opinions and opinions are different. Can they be universal? Xiao Bian carefully read everyone's replies, also asked the trailer manufacturers related personnel, the answer is not, I believe that looked at the following analysis we will understand.
â— The position of the tractor is not the same: it may lead to interference
Since the double-guided and dual-drive tractors have different driving forms, the weight of the vehicle's bearing is also different, so the position of the tractor is different. In general, the distance between the dual-drive head traction seat and the rear taillights is long, and the length of the double guide is short. In the case of the traction seat model, the height is the same, and the trailer is also the same, the double guided tractor can be double-drive semi-trailer, but the dual drive When the double-guided semi-trailer is attached to the front of the vehicle, the steering may interfere with the tractor, the taillights and fenders of the main vehicle may be easily damaged, and sometimes the frame of the main vehicle and the trailer may be damaged. Certain vehicles may adjust the position of the tractor pin. Solve the connection problem.
â— The wheelbase is different: it may cause the change of main force
In the case of traction seats with the same height and the same trailer, the general double-guided tractor can be equipped with a double-drive semi-trailer. By adjusting the position of the saddle, the dual-drive tractor can also be mounted on a double-guided trailer. .
However, this only solves the connection problem. When the manufacturer allocates a trailer according to the main vehicle, it also considers the distribution of the bearing capacity of each bridge of the vehicle, the load capacity of the main vehicle frame, and the trailer girder. Different types of tractors and trailers of different lengths are connected together. Due to the different positions of the traction seats, the positions of the traction pins may also be different, which may cause different wheelbases between the main vehicle trailers, which can lead to various bridges and beams of the vehicle. The change in force may cause problems such as increased fuel consumption of vehicles and vehicles, and increased wear of tires.
â— Postscript:
In fact, the reason why this issue is different is that everyone has different opinions. Under Xiaobian's analysis, we mainly noticed only whether the traction seat model is the same, whether the main trailer height is consistent, whether it can be connected, and ignores the problem of main interference, especially. Because different drive styles are different for the tractors, the wheelbase is different, and the problem of redistribution of the force caused by the vehicle is caused.
