Abstract
The utility model discloses an 'L'-shaped longitudinal beam of semitrailer, wherein a segment of portion which is upwards transited and is similar as a swan neck is arranged at the bottom of the longitudinal beam from back to front, and the size of the bottom of the swan neck is big in front and small at back, which is gradually transited, and the width size of the front bottom of the swan neck is bigger than the width size of the rear bottom of the swan neck, wherein the cross section of the longitudinal beam is in an 'L' shape, which is once stamped to form. The 'L'-shaped longitudinal beam of semitrailer has small weight and simple manufacture, which leads the manufacture cost of manufactures to be lowered.
Description
Technical field
The utility model relates to the manufacturing field of the superimposed trailer of automobile, especially a kind of longeron of superimposed trailer.
Background technology
The longeron of present superimposed trailer generally all uses the three block length bar steel plates cross-sectional plane that is welded to be the crossbeam of " worker " font, the longeron of " worker " font manufactures that program technology is more loaded down with trivial details, 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, and weight is bigger, increase the overall weight of vehicle frame, strengthened manufacturing cost virtually.
The utility model content
The purpose of this utility model provides a kind of L type longeron of superimposed trailer, has alleviated the quality of longeron, and makes simple.
For achieving the above object, the utility model adopts following technical scheme: a kind of " L " type longeron of superimposed trailer, longeron bottom by after one section upwards part of transition likeness in form gooseneck is arranged forward, and the front wide and rear narrow progressively transition of gooseneck place size, gooseneck front bottom width dimensions is characterized in that greater than gooseneck back bottom width size: the cross-sectional plane of described longeron is " L " type.
Described longeron is one time punching molded longeron.
The steel that described longeron adopts is A600 or A700.
" L " type longeron of the utility model superimposed trailer, quality is little, and makes simply, and manufacturing cost is reduced.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is the A-A view of Fig. 1;
Fig. 3 is the B-B view of Fig. 2;
The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, " L " type longeron 1 of superimposed trailer, the bottom of longeron 1 by after one section upwards part of transition likeness in form gooseneck 2 is arranged forward.The front wide and rear narrow progressively transition of the bottom size at gooseneck 2 places, gooseneck 2 front bottom width dimensions are greater than gooseneck back bottom width size.This longeron 1 adopts the steel plate of A600 or A700, and disposable punch forming.Adopt this longeron 1, make the weight saving of superimposed trailer, and this longeron 1 to manufacture technology simple, cost is low.
