Telescopic environment-friendly semitrailer

Abstract

The invention discloses a telescopic environment-friendly semitrailer, which comprises a front vehicle section, a middle vehicle section, a rear vehicle section, front wheels, middle wheels, rear wheels, a front vehicle section telescopic rod, a rear vehicle section telescopic rod and a towing device, wherein the towing device is arranged at the lower end of the front vehicle section, front wheelsare arranged on two sides of the front vehicle section, the front vehicle section is telescopically connected with the middle vehicle section through the front vehicle section telescopic rod, middlewheels are arranged on two sides of the middle vehicle section, the rear vehicle section is telescopically connected with the middle vehicle section through the rear vehicle section telescopic rod, and rear wheels are arranged on two sides of the rear vehicle section. The semitrailer body is telescopic; the size of the semitrailer is changed, when large-size goods need to be transported, the length of the semitrailer body can be adjusted according to actual conditions, the length of the semitrailer body can be adjusted in the front-back direction so that large-size objects can be transported,and when small-size objects are transported, the semitrailer body can be shortened, does not occupy space, is convenient to drive and occupies small space for parking.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a retractable environment-friendly semi-trailer. Background technique [0002] A semi-trailer is a trailer whose axle is placed behind the vehicle's center of gravity (when the vehicle is evenly loaded) and is equipped with a hitch that transmits horizontal and vertical forces to the tractor. Semi-trailers are generally three-axle semi-trailers, and their types are divided into 11-meter warehouse semi-trailers, 13-meter warehouse semi-trailers, and low-bed semi-trailers. It is a heavy-duty transport vehicle connected to the semi-trailer head through the traction pin. In the prior art, the semi-trailer is generally fixed in length. Generally, the semi-trailer is relatively long, and it is troublesome in the driving process, especially because the vehicle is too long, it is inconvenient to turn, and it also takes up space when parking. Neither will be fully loaded. Even if the w...

Problems solved by technology

In the prior art, the semi-trailer is generally fixed in length. Generally, the semi-trailer is relatively long, and it is troublesome in the driving process, especially because the vehicle is too long, it is inconvenient to turn, and it also takes up space when parking. Neither will be fully loaded. Even if the weight reaches the overload limit, the volume may not necessarily be overloaded, and there are also cases where the volume is large but the weight is not overloaded. Therefore, there is room for improvement.
