Abstract
The utility model discloses a kind of lightweight longeron.In longeron main body section, some irregularly-shaped holes (5) are set；The irregularly-shaped hole (5) is water-drop-shaped.This structure is the weight for alleviating longeron, and perforate is processed by punching press flange, and longeron stress reduces, and strengthens the bearing capacity of longeron.Longeron is not easy to break.
Description
Technical field
The utility model is related to trailer technical field, more particularly to a kind of lightweight longeron.
Background technology
In the prior art, the light-weighted mode of the longeron of trailer is：The circular port being evenly arranged is opened up on longeron.It lacks
Putting is：Although reducing the weight of longeron, light-weighted purpose is reached, circular port weight capacity is not protruded, have impact on
The intensity of trailer longitudinal beam.
Utility model content
The technical problem of load-bearing is influenceed in order to overcome prior art to open up circular port in longeron, the utility model provides one
Plant lightweight longeron.
A kind of lightweight longeron that the utility model is provided, some irregularly-shaped holes are set in longeron main body section；The abnormity
Hole is water-drop-shaped.This structure is the weight for alleviating longeron, and perforate is processed by punching press flange, and longeron stress reduces, and is strengthened
The bearing capacity of longeron.Longeron is not easy to break.
Wherein, the irregularly-shaped hole three is one group, sets some groups.
Wherein, the irregularly-shaped hole tip in the middle of every group is sophisticated positioned opposite with two other irregularly-shaped hole.
Wherein, every group of irregularly-shaped hole is arranged in isosceles triangle.
Wherein, the longeron main body section is I-shaped.
Wherein, the section of the irregularly-shaped hole is rotation L-shaped.This structure can strengthen the intensity of longeron, mitigate weight.
Wherein, the rectangular cross-section structure of the lower side board of longeron.
Wherein, the section of the web of longeron is integrated rectangle variable section structure.
Beneficial effect：This structure is the weight for alleviating longeron, and perforate is processed by punching press flange, and longeron stress subtracts
It is small, strengthen the bearing capacity of longeron.Longeron is not easy to break.
Brief description of the drawings
A kind of lightweight longitudinal beam structure figure that Fig. 1 is provided for the utility model embodiment.
Fig. 2 is enlarged drawing at Figure 1A.
Fig. 3 is Fig. 2 section B-B figures.
Fig. 4 is Fig. 1 D-D sectional views.
Fig. 5 is Fig. 1 E-E sectional views.
In figure：1st, lower side board；2nd, upper flange；3rd, lower wing plate；4th, web；5th, irregularly-shaped hole.
Specific embodiment
It is that the technical problem for solving the utility model, the technical scheme for using and the technique effect for reaching are clearer,
The utility model is described in further detail with reference to the accompanying drawings and examples.It is understood that described herein
Specific embodiment is used only for explanation the utility model, rather than to restriction of the present utility model.It also should be noted that, it is
It is easy to description, illustrate only part rather than the full content related to the utility model in accompanying drawing.
Fig. 1 to Fig. 5 is refer to, a kind of lightweight longeron of the present embodiment sets some irregularly-shaped holes in longeron main body section
5；The irregularly-shaped hole 5 is water-drop-shaped.The irregularly-shaped hole 5 three is one group, sets some groups.In the middle of every group irregularly-shaped hole tip with
Two other irregularly-shaped hole it is sophisticated positioned opposite.Every group of irregularly-shaped hole is arranged in isosceles triangle.The longeron main body section is
I-shaped.The section of the irregularly-shaped hole 5 is rotation L-shaped.The rectangular cross-section of the lower side board 1 of longeron.The web 4 of longeron cut
Face is rectangle.
Finally it should be noted that：Various embodiments above is only used to illustrate the technical solution of the utility model, rather than it is limited
System；Although being described in detail to the utility model with reference to foregoing embodiments, one of ordinary skill in the art should
Understand：It modifies to the technical scheme described in foregoing embodiments, or to which part or all technical characteristic
Equivalent is carried out, does not make the scope of essence disengaging each embodiment technical scheme of the utility model of appropriate technical solution.
