Background technology
In recent years, with the fast development in logistics transportation market, semitrailer is widely used, however design and
Vehicle frame and the wheelbase that would ordinarily be encountered trailer during making semi-trailer frame structure are longer, the discontinuity of longeron everywhere
The problems such as, easy to produce stress concentration or mutation in linear comer and cross sectional dimensions variation portion, it is therefore desirable to for half
The position of trailer longitudinal beam insufficient strength or weakness carries out the reinforcement measure of partial structurtes；Generally use is welded in the prior art
The mode of web carries out that longeron intensity is low and the reinforcement process at structural weak position, but reinforcing effect is poor, be easy to cause enterprise
The waste of material produces greatly the bending resistance of trailer longitudinal beam phenomena such as reinforcement position easy tos produce stress concentration
Influence, the deformation of complete vehicle structure is easily generated when generating side impact to trailer longitudinal beam, is repaired difficult；Greatly waste enterprise
The maintenance fund of industry, simultaneously for the personal safety of driver, there is also great security risks.
Invention content
The goal of the invention of the utility model：
Primarily to providing, a kind of overall construction intensity is high, and resistance side impact ability is strong, and counter-bending deformability is strong
Semi-trailer longitudinal beam structure, while effectively avoiding being welded with the problem of stress concentration generated after web, effectively ensure semitrailer
Transportation safety in transportational process, the effective service life for improving semi-trailer longitudinal beam, reduces the maintenance cost in enterprise's later stage,
Improve the economic benefit of enterprise.
The technical solution of the utility model is：
A kind of semi-trailer longitudinal beam structure, including upper flange and lower wing plate are provided, is installed between upper flange and lower wing plate
There are planar webs, the reinforcing block of isosceles trapezoidal structure is uniformly arranged at the both ends of planar webs, in the outermost side of reinforcing block
It is provided with elastomeric layer on face, is respectively arranged with and upper flange and lower wing plate in the upper and lower end of each reinforcing block
The upper right-angled trapezium reinforcing plate being welded and fixed and lower direct trapezoidal reinforcing plate；The reinforcing block of isosceles trapezoidal structure in planar webs
Between be provided with stress dispersion hole；It is welded with top panel in the upper end of upper flange, is welded in the lower end of lower wing plate following
Plate.
The elastomeric layer is set as elastic rubber.
It is two that the upper right-angled trapezium reinforcing plate is uniformly arranged between upper flange and reinforcing block；Described is lower direct
There are two trapezoidal reinforcing plate is uniformly arranged between lower wing plate and reinforcing block.
The stress dispersion hole is 4 be arranged symmetrically in matrix structure.
The thickness of the upper surface of described plate be planar webs thickness one third, it is described below plate thickness also be plane
The one third of web thickness.
The both ends of the upper flange are provided with arc convex.
The utility model has the beneficial effects that：
The semi-trailer longitudinal beam overall construction intensity of the structure setting is high, and anti-side face jolt capacity is strong, counter-bending deformability
By force, the problem of stress concentration generated after being welded with web is effectively avoided, is effectively guaranteed semitrailer in transportational process
Transportation safety effectively raises the service life of semi-trailer longitudinal beam, reduces the maintenance cost in enterprise's later stage, improves enterprise
Economic benefit.
Description of the drawings
Fig. 1 is the main structure diagram of the utility model；
Fig. 2 is the side structure schematic view of the utility model.
In figure；1 is upper flange；2 be lower wing plate；3 be planar webs；4 be reinforcing block；5 be elastomeric layer；6 be upper straight

Protrusion.
Specific implementation mode
Specific embodiment of the present utility model is described in detail below in conjunction with attached drawing.
As shown in Fig. 1~2, provide a kind of semi-trailer longitudinal beam structure, including upper flange 1 and lower wing plate 2, in upper flange and
Planar webs 3 are installed between lower wing plate, the reinforcing block 4 of isosceles trapezoidal structure is uniformly arranged at the both ends of planar webs,
It is provided with elastomeric layer 5 on the outermost side end face of reinforcing block, is respectively set in the upper and lower end of each reinforcing block
There are the upper right-angled trapezium reinforcing plate 6 being welded and fixed with upper flange and lower wing plate and lower direct trapezoidal reinforcing plate 7；In planar webs
Stress dispersion hole 8 is provided between the reinforcing block of isosceles trapezoidal structure；It is welded with top panel 9 in the upper end of upper flange, under
The lower end of wing plate is welded with lower panel 10.
The elastomeric layer is set as elastic rubber.
It is two that the upper right-angled trapezium reinforcing plate is uniformly arranged between upper flange and reinforcing block；Described is lower direct
There are two trapezoidal reinforcing plate is uniformly arranged between lower wing plate and reinforcing block.
The stress dispersion hole is 4 be arranged symmetrically in matrix structure.
The thickness of the upper surface of described plate be planar webs thickness one third, it is described below plate thickness also be plane
The one third of web thickness.
The both ends of the upper flange are provided with arc convex 11.
The semi-trailer longitudinal beam structure of the structure setting has been uniformly arranged isosceles trapezoidal structure by the both ends in planar webs
Reinforcing block, and be respectively arranged in the upper and lower end of each reinforcing block and be welded and fixed with upper flange and lower wing plate
