Abstract
The utility model discloses a semi-trailer integration longitudinal beam, comprising a front end of the longitudinal beam hung on the semi-trailer head, a longitudinal beam back end for bearing the weight and arranged at the different horizontal surfaces with the front end of the longitudinal beam and a beam neck part for connecting the front end of the longitudinal beam and the back end of the longitudinal beam, characterized in that the longitudinal beam is casted for one time. The semi-trailer integration longitudinal beam is formed by the one-time casting technology, thus the semi-trailer integration longitudinal beam has features of simple process technology, low cost, good fatigue resistance, light weight and not-easy deformation.
Description
Technical field
The utility model relates to a kind of superimposed trailer field of large-scale transport trolley, especially relates to the integrated longeron of a kind of superimposed trailer.
Background technology
Semi-trailer frame is the most important load bearing component of superimposed trailer, and chassis side rail is one of vital part wherein.At present, semi-trailer frame is general all to be formed by two longerons and some crossbeam manufacturings being located between two longerons, wherein two longerons generally all use the three block length bar steel plates crossbeam of cross-sectional plane for " worker " font that be welded, this manufacturing course of longeron is loaded down with trivial details, poor dimensional precision, technology trouble, labour intensity is big, production efficiency is low, particularly when three block length bar steel plates weld, need welding four roads, yielding distortion, and steel plate is thicker, weight is bigger, increase the overall weight of vehicle frame, strengthened manufacturing cost virtually.
Summary of the invention
For solving above problem, the utility model provides that a kind of processing technology is simple, cost is low, the integrated longeron of good, in light weight, the on-deformable superimposed trailer of fatigue resistance.
The utility model is realized by following technical measures, the integrated longeron of a kind of superimposed trailer, comprise the longeron front end that hangs over headstock, be used for being arranged at the longeron rear end of different level and being connected the longeron front end and the beam neck of longeron rear end with the longeron front end of load capacity, described longeron is disposable casting.The upper limb of the upper limb of longeron rear end and longeron front end is on same horizon as required, and the lower edge of longeron rear end is lower than the lower edge of longeron front end.It is shaped form that the longeron rear end can also be set.
The cross-sectional plane of above-mentioned longeron can be an I-shape; It also can be the L font; It can also be the U font.
Because the utility model adopts the processes of disposable casting to form, make to the utlity model has that processing technology is simple, cost is low, good, in light weight, the on-deformable advantage of fatigue resistance.

The specific embodiment
Below in conjunction with embodiment and contrast accompanying drawing the utility model is described in further detail.
Embodiment 1:
With reference to Fig. 1, Fig. 2, the integrated longeron of a kind of superimposed trailer of disposable casting, its cross-sectional plane is the U font, comprises the longeron front end 1 that hangs over headstock, the beam neck 2 that is arranged at the longeron rear end 3 of different level with longeron front end 1 and is connected longeron front end 1 and longeron rear end 3 that is used for load capacity.
Embodiment 2:
With reference to Fig. 3, Fig. 4, the integrated longeron of a kind of superimposed trailer of disposable casting, its cross-sectional plane is an I-shape, comprise the longeron front end 1 that hangs over headstock, the longeron rear end 3 that is used for load capacity and the beam neck 2 that connects longeron front end 1 and longeron rear end 3, wherein the upper limb of the upper limb of longeron rear end 3 and longeron front end 1 is on same horizon, and the lower edge of longeron rear end 3 is lower than the lower edge of longeron front end 1.
Embodiment 3:
With reference to Fig. 5, Fig. 6, the integrated longeron of a kind of superimposed trailer of disposable casting, its cross-sectional plane is the L font, comprise the longeron front end 1 that hangs over headstock, the longeron rear end 3 that is used for load capacity and the beam neck 2 that connects longeron front end 1 and longeron rear end 3, wherein longeron rear end 3 is umbilicate shaped form.
More than be that the structure of the integrated longeron of the utility model superimposed trailer is set forth, be used for helping to understand the utility model, but embodiment of the present utility model be not restricted to the described embodiments.Anyly do not deviate from the change done under the utility model principle, modification, substitute, combination, simplify, all should be the substitute mode of equivalence, be included within the protection domain of the present utility model.
