Description
Technical field
The utility model relates to the board-like H-girder of a kind of trailer bending, in particular, particularly relates to the board-like H-girder of trailer bending that a kind of median plate adopts waveform curved surface, fold-line-shaped curved surface or corrugated curved surface.
Background technology
Trailer longitudinal beam (being commonly called as crossbeam, H-girder) is the main load-supporting part of trailer or semi-trailer frame, and the vehicle frame of trailer or superimposed trailer is made up of the longeron that two are parallel to each other, to realize the supporting role to crossbeam and base plate.Anti-twist, the fatigue resistance of longeron determine the service life of whole vehicle frame, and in the Long-Time Service process of vehicle frame, the cargo weight of loading road conditions that are large, that travel are complicated and changeable, therefore more and more higher to the requirement of strength of longeron.
Longeron is made up of upper parallel plate, lower parallel plate and median plate, and upper parallel plate and lower parallel are arranged, and median plate is between upper parallel plate and lower parallel plate, and in realization, parallel plate and lower parallel plate is fixedly connected with effect.But existing upper parallel plate, lower parallel plate and median plate are aspect, form the longeron of so-called I-beam section shape.Along with trailer weight-saving development tendency, the longeron of this I-beam section shape can not meet anti-twist, the fatigue resistance of longeron gradually, needs a kind of lightweight that can realize longeron badly, can ensure that again the i-beam structure of longeron intensity meets the demands.
Summary of the invention
The utility model, in order to overcome the shortcoming of above-mentioned technical matters, provides the board-like H-girder of a kind of trailer bending.
The board-like H-girder of trailer bending of the present utility model, comprise parallel plate, lower parallel plate and median plate, upper parallel plate and lower parallel are arranged, and median plate is between upper parallel plate and lower parallel plate, and upper parallel plate and lower parallel plate are fixed by median plate; It is characterized in that: described median plate is waveform curved surface, fold-line-shaped curved surface or corrugated curved surface.
Median plate is between upper parallel plate and lower parallel plate, and become plumbness with upper parallel plate with lower parallel plate, the upper surface of median plate and upper parallel plate weld together, lower surface and lower parallel plate weld together, go up the girder work that parallel plate, lower parallel plate and median plate just define stable " I-shaped " shape like this.By median plate being set to waveform curved surface, fold-line-shaped curved surface or corrugated curved surface, not only effectively increase the area of contact of median plate and upper parallel plate and lower parallel plate, but also be equivalent to the length extending median plate, make the whole longeron formed have stronger anti-twist, fatigue resistance.
The board-like H-girder of trailer bending of the present utility model, two long sides of described upper parallel plate and lower parallel plate are provided with thickening part, edge.By arranging thickening part, edge in the both sides of upper and lower parallel plate, effectively increase the intensity of upper and lower parallel plate.
The board-like H-girder of trailer bending of the present utility model, two long sides of described upper parallel plate and lower parallel plate are provided with edge bend.By arranging edge folds in the both sides of upper and lower parallel plate, effectively increase the intensity of upper and lower parallel plate.
The beneficial effects of the utility model are: the board-like H-girder of trailer bending of the present utility model, by the median plate connecting upper parallel plate and lower parallel plate is set to waveform curved surface, fold-line-shaped curved surface or corrugated curved surface, not only increase the area of contact of median plate and upper and lower parallel plate, but also be equivalent to the length extending median plate, formed trailer longitudinal beam is made to have larger anti-twist, fatigue resistance, ensure that the intensity of formed trailer or superimposed trailer, extend the service life of trailer.
Meanwhile, by the side design thickening part, edge of upper parallel plate and lower parallel plate or edge folds, effectively increase the intensity of upper and lower parallel plate, further enhancing the intensity of trailer longitudinal beam.

Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
embodiment 1as shown in Figure 1, give the front view of board-like the first embodiment of H-girder of trailer of the present utility model bending, Fig. 2 gives the structural representation in A-A cross section in Fig. 1, it is made up of upper parallel plate 1, lower parallel plate 2 and median plate 3, shown upper parallel plate 1 is arranged with lower parallel plate 2 one-tenth horizontality, and median plate 3 is between upper parallel plate 1 and lower parallel plate 2.The upper surface of median plate 3 and upper parallel plate 1 weld together, lower surface and lower parallel plate 2 weld together, make parallel plate 1, lower parallel plate 2 and median plate 3 define the longeron of " I-shaped " shape.
