Abstract
The utility model relates to a three -section gooseneck type semi -trailer longitudinal beam belongs to the frame field of compriseing component vertical and transversal arrangement, the longeron back end that the pterygoid lamina is formed under pterygoid lamina, trailing web, back are gone up with the back to the preceding longeron anterior segment of going up pterygoid lamina, leading web, the preceding component of pterygoid lamina down, the utility model discloses a technical essential lies in: be equipped with the longeron middle section between longeron anterior segment and the longeron back end, this longeron middle section by in preceding in pterygoid lamina, back pterygoid lamina, well web in with down the pterygoid lamina forms, preceding go up the pterygoid lamina and preceding under be equipped with a gusset between the pterygoid lamina to it all is through welded joint to go up between each subassembly. Through the longeron middle section that sets up, eliminated among the prior art unreliability that the circular arc brought of longeron anterior segment and the design of longeron back end connection place, it is right to make the utility model discloses a longeron is strengthened easily and is satisfied the reliability, simultaneously, just only can satisfy the modularized design that customer's differentiation required through the size that changes minority member, be convenient for realize its standardized, big quick production in batches.
Description
Technical field
The utility model relates to a kind of three sections of Gooseneck-type semitrailer longerons, belongs to the vehicle frame field that the component arranged by vertical and horizontal forms.
Background technology
Current semi-trailer longitudinal beam adopts two sectional type gooseneck structure mostly, and the web served as by steel plate welds splicing with wing plate and forms.There is many weak points in this two sectional type gooseneck structure.One, the poor reliability of longeron at its gooseneck circular arc place of this superimposed trailer, it not only bears moment of flexure, also bears moment of torsion and the impulsive force of complex road condition in the process that vehicle travels, and is easy to damage; Its two, the longitudinal-beam web plate at gooseneck place is complex-shaped, and stock utilization is low; They are three years old, the saddle height of different tractor truck is different, and before and after superimposed trailer, the drop of platform needs corresponding change, so the size at semi-trailer longitudinal beam gooseneck place is just different, superimposed trailer sample, cannot meet modularization, normalisation, the needs produced fast in enormous quantities.
Utility model content
The purpose of this utility model to solve the deficiencies in the prior art, provides a kind of three sections of Gooseneck-type semitrailer longerons, is convenient to strengthen, easily meet reliability to its weak link, is convenient to realize its modularization, normalisation, production fast in enormous quantities.
The utility model relates to a kind of three sections of Gooseneck-type semitrailer longerons, comprise front upper flange, leading web, the longitudinal beam front section of front lower wing plate composition and the longeron back segment that forms of rear upper flange, trailing web, rear lower wing plate, longeron stage casing is provided with between longitudinal beam front section and longeron back segment, this longeron stage casing is made up of front middle wing plate, rear middle wing plate, median ventral plate and middle lower wing plate, a gusset is provided with, all by weld connection between each assembly above between front upper flange and front lower wing plate.
By the longeron stage casing arranged, eliminate the unreliability that circular arc that in prior art, longitudinal beam front section and longeron back segment connection place are designed brings, make easily strengthen longeron of the present utility model and meet reliability; Meanwhile, the size only by change front upper flange, middle wing plate and median ventral plate just can meet the modular design that client's differentiation requires, is convenient to realize its normalisation, production fast in enormous quantities.
Described median ventral plate two outside upper weld connection have brace panel one, the lower surface weld connection of this brace panel one upper end and front lower wing plate; Trailing web two outside upper weld connection have brace panel two, the front end face of this brace panel two and rear middle wing plate weld connection; The connection place weld connection of front lower wing plate and front middle wing plate has triangle brace panel.These the three kinds of brace panels arranged all improve the reliability of longeron.
Working process and principle:
Longeron of the present utility model forms by three sections, and the setting in longeron stage casing instead of by direct steel plate arc transition between original longeron front and rear sections, and its unreliability brought also is eliminated thereupon; The various brace panels arranged are also for the reliability of whole longeron ensures.
Compared with prior art, the beneficial effect that the utility model has is:
By the longeron stage casing arranged, eliminate the unreliability that circular arc that in prior art, longitudinal beam front section and longeron back segment connection place are designed brings, make easily strengthen longeron of the present utility model and meet reliability; Meanwhile, the size only by change front upper flange, middle wing plate and median ventral plate just can meet the modular design that client's differentiation requires, is convenient to realize its normalisation, production fast in enormous quantities, and these three kinds of brace panels of setting all improve the reliability of longeron.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, leading web; 2, front upper flange; 3, front lower wing plate; 4, gusset; 5, front middle wing plate; 6, rear middle wing plate; 7, rear upper flange; 8, rear lower wing plate; 9, trailing web; 10, brace panel two; 11, median ventral plate; 12, middle lower wing plate; 13, brace panel one; 14, triangle brace panel.
Detailed description of the invention
Contrast accompanying drawing below, detailed description of the invention of the present utility model is described in further detail.
Three sections of Gooseneck-type semitrailer longerons as shown in Figure 1, comprise front upper flange 2, longitudinal beam front section that leading web 1, front lower wing plate 3 form and the longeron back segment that forms of rear upper flange 7, trailing web 9, rear lower wing plate 8, longeron stage casing is provided with between longitudinal beam front section and longeron back segment, this longeron stage casing is made up of with middle lower wing plate 12 front middle wing plate 5, rear middle wing plate 6, median ventral plate 11, a gusset 4 is provided with between front upper flange 2 and front lower wing plate 3, median ventral plate 11 two outside upper weld connection have brace panel 1, the lower surface weld connection of this brace panel 1 upper end and front lower wing plate 3; Trailing web 9 two outside upper weld connection have brace panel 2 10, the front end face of this brace panel 2 10 and rear middle wing plate 6 weld connection; Front lower wing plate 3 has triangle brace panel 14 with the connection place weld connection of front middle wing plate 5.Above between each assembly all by weld connection.
Working process:
Longeron of the present utility model forms by three sections, back segment bearing goods, and the setting in longeron stage casing instead of between original longeron front and rear sections directly uses steel plate arc transition, and its unreliability brought also is eliminated thereupon; The brace panel also successful arranged, for the reliability of whole longeron ensures; Meanwhile, only need change the superimposed trailer that a few component is just applicable to different size, for its realize modularization, normalisation, in enormous quantities production fast provide possibility.
