Abstract

The utility model discloses a novel semi -trailer beam, including two parallel spaced longeron risers, be provided with the crossbeam riser that a plurality of cross sections appeared for C between two longeron risers, the support bedplate has all been riveted to crossbeam riser both ends top and bottom, it rivets with the longeron riser mutually to support the bedplate. The beneficial effects of the utility model are that: structural design is reasonable, does not need the both sides welding, has saved a large amount of manpower and materials, and long -time the use is difficult to take place deformation, has shortened the assemble duration moreover, has improved production efficiency greatly.

Description

A kind of Novel semi-trailer beam

Technical field

This utility model relates to a kind of Novel semi-trailer beam.

Background technology

Current semitrailer has occupied main status in China's transport service, and the performance quality of semitrailer crossbeam is related to the quality of semitrailer performance.Existing, semitrailer girder structure often adopts two-weld process, in the course of processing, each cross section in two faces all needs two-sided welding, this not only consumes substantial amounts of manpower and materials, long-time use is susceptible to deformation, and increases welding and upset, installation time, has been greatly reduced production efficiency simultaneously.

Summary of the invention

For solving above technical deficiency, this utility model provides a kind of time saving and energy saving, is unlikely to deform, the Novel semi-trailer beam that production efficiency is high.

This utility model is realized by following measures:

A kind of Novel semi-trailer beam of the present utility model, longeron riser including two parallel interval, being provided with the crossbeam riser that some cross sections are C shape between two longeron risers, support seat board has all been riveted in described top, crossbeam riser two ends and bottom, and described support seat board is riveted mutually with longeron riser.

The part that above-mentioned support seat board and crossbeam riser are riveted mutually is isosceles trapezoid, be narrow base and outside is wide base inside this isosceles trapezoid, supports the wide base vertical outside seat board and is bent with connection crimp, and described connection crimp is affixed with longeron riser sidewall and merges riveted joint.

The isosceles trapezoid part that above-mentioned support seat board and crossbeam riser are riveted mutually adopts four rivets to rivet mutually, and four rivet arrangement squarelys.

Above-mentioned connection crimp is fitted with longeron riser sidewall and adopts four rivets to rivet mutually, and four rivet spaces are in a row side by side.

Above-mentioned crossbeam riser has loss of weight through hole.

The beneficial effects of the utility model are: reasonable in design, it is not necessary to two-sided welding, save substantial amounts of manpower and materials, and deformation is less likely to occur long-time use, and shortens installation time, substantially increases production efficiency.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Fig. 2 supports the structural representation after seat board is connected with crossbeam riser.

Fig. 3 is the plan structure schematic diagram of Fig. 2.

Fig. 4 is the side structure schematic diagram of Fig. 2.

Wherein: 1 longeron riser, 2 crossbeam risers, 3 support seat board, 4 loss of weight through holes, and 5 connect crimp.

Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is done further detailed description:

As shown in Figure 1, a kind of Novel semi-trailer beam of the present utility model, longeron riser 1 including two parallel interval, the crossbeam riser 2 that some cross sections are C shape it is provided with between two longeron risers 1, support seat board 3 has all been riveted in top, crossbeam riser 2 two ends and bottom, supports seat board 3 and rivets with longeron riser 1 phase.Make existing welding into riveted joint, it is ensured that under the premise of bonding strength, not only saved manpower and materials, and improve production efficiency.

As shown in Figure 2,3, 4, supporting the part that seat board 3 and crossbeam riser 2 phase rivet is isosceles trapezoid, is narrow base and outside is width base inside this isosceles trapezoid, and the design of isosceles trapezoid improves the ability of extrusion stretching, it is not easy to deform upon.In order to convenient for assembly, supporting the wide base vertical outside seat board 3 and be bent with connection crimp 5, connection crimp 5 is affixed with longeron riser 1 sidewall and merges riveted joint.Support seat board 3 to rivet mutually with isosceles trapezoid part four rivets of employing that crossbeam riser 2 phase is riveted, and four rivet arrangement squarelys.Connect crimp 5 fit with longeron riser 1 sidewall and adopt four rivets to rivet mutually, and four rivet spaces are in a row side by side.Crossbeam riser 2 has loss of weight through hole 4, to alleviate weight, conservation.

The above is only the preferred implementation of this patent; it should be pointed out that, for those skilled in the art, under the premise without departing from the art of this patent principle; can also making some improvement and replacement, these improve and replace the protection domain that also should be regarded as this patent.
