Gooseneck module device of covariant module-separation-and reunion type semi-trailer

Abstract

The invention discloses a gooseneck module device of a covariant module-separation-and reunion type semi-trailer. The gooseneck module device is provided with two types of gooseneck device modules, namely a convex-concave connection gooseneck and a double-pin connection gooseneck. The gooseneck module device of the covariant module-separation-and reunion type semi-trailer has technical advantages in multiple aspects, and therefore good market prospect and economic benefits can be achieved certainly.

Description

technical field [0001] The invention relates to the technical field of semi-trailers, in particular to a gooseneck module device of a variable modular clutch type semi-trailer. Background technique [0002] As we all know, semi-trailers are closely related to national key construction, national economic development, social development and the development of heavy vehicle equipment technology; A special transport vehicle for the transportation of bulky goods. [0003] Existing traction semi-trailer: divided into two independent parts of tractor head and semi-trailer. In the existing traditional semi-trailer technology, the structure is that the gooseneck, loading surface, frame girder, load-bearing device, wheel set device, suspension system, etc. are welded and integrated integral structures; [0004] Obviously, the existing semi-trailer still has the following technical defects: [0005] Among them, the traditional semi-trailer is generally connected with the gooseneck t...

Problems solved by technology

[0005] Among them, the traditional semi-trailer is generally connected with the gooseneck traction pin of the semi-trailer through the saddle of the tractor head; figure 1 As shown, the bottom of the gooseneck device in the prior art is welded with a traction pin, and the traction pin is inserted into the mounting hole at the saddle position behind the front of the vehicle to form a pin-hole fit, thereby realizing the rigidity between the front of the semi-trailer and the body. Connection; Obviously, the gooseneck device and the traction pin of the existing semi-trailer have rigidly connected the front and the body, so when the semi-trailer is driving on a bumpy road, the rigid connection between the front and the body causes the front and body to be rigidly connected. The vibration amplitude is very large, and it does not have the effect of rotational shock absorption;

[0006] At the same time, the gooseneck device of the existing semi-trailer cannot realize the lifting function, which is not conducive to the disassembly operation of the semi-trailer, easily affects the disassembly efficiency, and brings inconvenience to use
