Gooseneck trailer longitudinal beam spliced in segmented manner, trailer frame and trailer

Abstract

The invention provides a gooseneck trailer longitudinal beam spliced in a segmented manner. The gooseneck trailer longitudinal beam spliced in the segmented manner comprises a front longitudinal beambody, a rear longitudinal beam body and a splicing structure; the front longitudinal beam body and the rear longitudinal beam body are divided at the gooseneck position and connected together throughthe splicing structure; the splicing structure comprises a connection vertical plate; the two faces of the connection vertical plate are fixed to a web plate of the front longitudinal beam body and aweb plate of the rear longitudinal beam body correspondingly; the bottom end of the connection vertical plate is fixed to a lower wing plate of the front longitudinal beam body; the top end of the connection vertical plate is fixed to the front longitudinal beam body; and the tail end of the lower wing plate of the front longitudinal beam body extends backwards so that a lower wing plate of the rear longitudinal beam body can be in lap joint to the lower wing plate of the front longitudinal beam body. The gooseneck trailer longitudinal beam spliced in the segmented manner has the advantages that segmented design is performed, matching with frames in different gooseneck step height differences is achieved, and the connection structure is steady and simple.

Description

technical field [0001] The invention relates to a trailer structure, in particular to a section spliced ​​gooseneck trailer longitudinal beam, a trailer frame with the longitudinal beam, and a trailer with the trailer frame. Background technique [0002] According to the national policy’s restriction on the profile height of barn trailers, within the profile height range specified by the regulations, low-load trailers can carry a large cargo capacity and stable driving and transportation. Therefore, low-load trailers with gooseneck steps have become mainstream models in the market. [0003] In the actual application process of the market, gooseneck trailers will design gooseneck steps of different heights according to the requirements of goods and loads. At present, in the actual production process of gooseneck trailers, the longitudinal beams of the whole vehicle need to be processed as a whole, but because gooseneck trailers need to match different The difference in the he...

Problems solved by technology

[0003] In the actual application process of the market, gooseneck trailers will design gooseneck steps of different heights according to the requirements of goods and loads. At present, in the actual production process of gooseneck trailers, the longitudinal beams of the whole vehicle need to be processed as a whole, but because gooseneck trailers need to match different The difference in the height of the goose neck (difference in the height of the bottom plate) leads to a large number of models of the web of the longitudinal beam, which has the problems of high processing difficulty and low material utilization rate. Moreover, the length of the longitudinal beam of the whole vehicle is long, occupying a large space, and difficult for logistics and transportation, etc. short board
