Fig. 1 is the perspective view of Gooseneck-type semitrailer vehicle frame of the present utility model.
Fig. 2 is the perspective view of the longeron on the Gooseneck-type semitrailer of the present utility model.
The specific embodiment
In order to further specify principle of the present utility model and structure, now in conjunction with the accompanying drawings preferred embodiment of the present utility model is elaborated.
The Gooseneck-type semitrailer vehicle frame that Gooseneck-type semitrailer of the present utility model comprises suspension and is arranged at described suspension top.
See also shown in Figure 1ly, Gooseneck-type semitrailer vehicle frame of the present utility model comprises two side bars 1, two longerons 2 and many crossbeams 3, and described Gooseneck-type semitrailer vehicle frame can also comprise a plurality of oblique bracing frames 4.
Described two side bars 1 are set in parallel in the both sides of described Gooseneck-type semitrailer vehicle frame, and the structure of described side bar 1 is existing structure on the existing Gooseneck-type semitrailer vehicle frame, and this is not described in detail again.
