Abstract
The utility model belongs to the semitrailer field, concretely relates to novel semi -trailer longitudinal beam, including web and the last pterygoid lamina of locating these upper and lower both ends of web respectively and pterygoid lamina down, wherein, the higher authority of web and last pterygoid lamina are equipped with a plurality of stress dispersion holes along vertical arc structure that arches up for the centre of semi -trailer longitudinal beam on the vertical cross -section of web. Novel semi -trailer longitudinal beam, be equipped with the stress dispersion hole, when reducing self weight, can effectively prevent stress concentration, increased and born intensity, and the utility model discloses a centre is high slightly, both sides horizontally structure, this kind of structure simple process, and intensity is high, and the amount of deflection is little.
Description
Technical field
The utility model relates to a kind of novel semi-trailer longeron, belongs to superimposed trailer field.
Background technology
Current superimposed trailer all belongs to 2 support beams, that is: anterior support point is traction pin plate, supported back point is suspension gear, because the quality of semi-trailer longitudinal beam own is very heavy, so when zero load and fully loaded two states, the centre of its semi-trailer longitudinal beam all can produce waist phenomenon of collapsing to a certain degree, namely have dropped an amount of deflection size.
In order to solve above waist phenomenon of collapsing, adopt under normal circumstances in two ways: a kind of is that being designed to by web upper when cutting longitudinal-beam web plate is all arch below, and another kind is that the technique of employing sparking arch after longeron completion is reached arch.
The arch that first method obtains, the lower wing plate of its semi-trailer longitudinal beam is arch equally, this structure on the one hand traction pin plate place, hanging position lower wing plate is variable section, make faint radian, the longeron not being straight line for lower wing plate is inconvenient to process, seem that afterbody stays during zero load on the other hand, the more important thing is that the structural strength of lower wing plate entirety is slightly weak.
Another kind method is difficult to acquisition and arches up uniformly longeron, and sparking degree is difficult to grasp, and the longeron for high strength steel can not adopt this technique especially.
Based on above analysis, design the novel semi-trailer longeron that a kind of intensity is high, amount of deflection is little, become and will solve major issue now.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide the novel semi-trailer longeron that a kind of intensity is high, amount of deflection is little.
Novel semi-trailer longeron described in the utility model, comprise web and be located at upper flange and the lower wing plate of this web upper/lower terminal respectively, wherein, the top of web and upper flange are the middle arcuate structure arched up along the longitudinal direction of semi-trailer longitudinal beam, and the vertical section of web is provided with multiple stress dispersion hole.
The top of web and upper flange are middle arcuate structure arch up along the longitudinal direction of semi-trailer longitudinal beam, and this centre is slightly high, the structure of both sides level, and simply, intensity is high, and amount of deflection is little for technique; Be provided with stress dispersion hole, the utility model own wt can be reduced on the one hand, can effectively prevent stress from concentrating on the other hand.
The top of described web and upper flange equal the deflection value of at full load semi-trailer longitudinal beam along the height h that the longitudinal direction of semi-trailer longitudinal beam arches up, and make superimposed trailer at full load, base plate can be in horizontality.
The edge in described stress dispersion hole is provided with flange, effectively can prevent stress from concentrating, increase web intensity.
Described stress dispersion hole is evenly distributed on the vertical section of web.
The beneficial effect that the utility model is compared with prior art had is:
Novel semi-trailer longeron described in the utility model, is provided with stress dispersion hole, while minimizing own wt, effectively can prevent stress from concentrating, add bearing strength, and the utility model is that centre is slightly high, the structure of both sides level, this structural manufacturing process is simple, and intensity is high, and amount of deflection is little.

Fig. 2 is the A-A cutaway view in Fig. 1.
In figure: 1, lower wing plate; 2, web; 3, upper flange; 4, stress dispersion hole; 5, flange.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figure 1 and Figure 2, novel semi-trailer longeron described in the utility model, comprise web 2 and be located at upper flange 3 and the lower wing plate 1 of this web 2 upper/lower terminal respectively, wherein, the top of web 2 and upper flange 3 are the middle arcuate structure arched up along the longitudinal direction of semi-trailer longitudinal beam, and the vertical section of web 2 is provided with multiple stress dispersion hole 4.
The top of web 2 and upper flange 3 are middle arcuate structure arch up along the longitudinal direction of semi-trailer longitudinal beam, and this centre is slightly high, the structure of both sides level, and simply, intensity is high, and amount of deflection is little for technique; Be provided with stress dispersion hole 4, the utility model own wt can be reduced on the one hand, can effectively prevent stress from concentrating on the other hand.
In the present embodiment: the top of web 2 and upper flange 3 equal the deflection value of at full load semi-trailer longitudinal beam along the height h that the longitudinal direction of semi-trailer longitudinal beam arches up, and make superimposed trailer at full load, base plate can be in horizontality; The edge in stress dispersion hole 4 is provided with flange 5, effectively can prevent stress from concentrating, increase web 2 intensity; Stress dispersion hole 4 is evenly distributed on the vertical section of web 2.
Novel semi-trailer longeron described in the utility model, is provided with stress dispersion hole 4, while minimizing own wt, effectively can prevent stress from concentrating, add bearing strength, and the utility model is that centre is slightly high, the structure of both sides level, this structural manufacturing process is simple, and intensity is high, and amount of deflection is little.
The technical solution of the utility model can apply to upper arch process and the structure design of the various semi-trailer longitudinal beams such as straight beam novel semi-trailer longeron, low dull and stereotyped novel semi-trailer longeron, little gooseneck type novel semi-trailer longeron, difference is, according to the cargo weight of the configuration parameter of the wheelbase of superimposed trailer, longeron, carrying, the more rational h value of needs must be calculated.
