Abstract
The utility model discloses a vehicle chassis back end beam assembly, including the crossbeam of a plurality of different length and the stand of a plurality of different length, crossbeam and stand axial lead mutually perpendicular, adjacent crossbeam and stand cross cruciate fixation form a plurality of space, the length of crossbeam is all inequality, the length of stand is also inequality, crisscross fixed together can with the better dispersion of the power that the bridge frame received to different stands and the crossbeam on, avoid splitting in that a certain position is whole, simultaneously, crossbeam and stand can form a plurality of space for install the gearbox, hang and fix his route of pipe line.
Description
Technical field
The utility model relates to a kind of car chassis back segment crossbeam assembly.
Background technology
Vehicle frame is the spine of truck, and the installation not being only other parts provides space, also bears various force and moment.Vehicle frame has a lot of form, and its posterior segment crossbeam assembly is multiplex installs change speed gear box, hang and fix his route of pipe line, requires that it not only will have enough intensity, also will provide enough spaces.
In the prior art, car chassis is important parts in whole car production technique, and car chassis forms primarily of multiple crossbeam.In traditional technique, crossbeam generally adopts bolt and nut to be fixedly connected with, this kind is connected in the actual travel process of automobile and easily causes damage to bolt and nut, simultaneously traditional car chassis crossbeam is all generally an independent crossbeam, this kind of design produces larger burden to single crossbeam, shortens its service life.
Utility model content
For solving the problems of the technologies described above, the utility model proposes a kind of Stability Analysis of Structures and the larger car chassis back segment crossbeam assembly in space, reducing wearing and tearing to reach, alleviate crossbeam burden and extend the object in service life of crossbeam.
In order to achieve the above object, the technical solution of the utility model is as follows:
A kind of car chassis back segment crossbeam assembly, comprise the crossbeam of some different lengths and the column of some different lengths, described crossbeam is mutually vertical with column axial line, adjacent crossbeam and column right-angled crossing are fixed, form several spaces, the length of crossbeam is all not identical, the length of column is not identical yet, the staggered power that bridge vehicle frame can be subject to that is fixed together better is distributed on different columns and crossbeam, avoid in the entirety fracture of some positions, simultaneously, crossbeam and column can form several spaces, for installing change speed gear box, hang and fix his route of pipe line.
As a kind of preferred version of car chassis back segment crossbeam assembly described in the utility model, described crossbeam is all not identical with length with the spatial altitude that column is formed, and different spaces can accommodating different product.
As a kind of preferred version of car chassis back segment crossbeam assembly described in the utility model, described crossbeam and column are made by rectangle steel, can provide enough intensity, can alleviate again overall weight.
As a kind of preferred version of car chassis back segment crossbeam assembly described in the utility model, described crossbeam assembly comprises three crossbeams and four root posts, and wherein the length of first crossbeam, second cross beam, the 3rd crossbeam reduces successively; First column is identical with the second strut length, 3rd column is identical with the 4th strut length, first column and the second strut length are less than the 3rd column and the 4th strut length, first column and the second column abut against and are arranged between first crossbeam and second cross beam together, 3rd column is fixed on second cross beam end and is fixedly connected with first crossbeam, and the 4th column is parallel with the 3rd column and be fixed on the end of first crossbeam; 3rd column is fixedly connected with the 3rd crossbeam with the 4th column lower end.
As a kind of preferred version of car chassis back segment crossbeam assembly described in the utility model, described second cross beam lower end is fixedly connected with at least diagonal ligament, and diagonal ligament is fixedly connected with bridge vehicle frame.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein: 1, first crossbeam 2, second cross beam 3, the 3rd crossbeam 4, first column 5, second column 6, the 3rd column 7, the 4th column 8, diagonal ligament
Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is described in further detail.
As shown in Figure 1, a kind of car chassis back segment crossbeam assembly, comprise the crossbeam of some different lengths and the column of some different lengths, described crossbeam is mutually vertical with column axial line, and adjacent crossbeam and column right-angled crossing are fixed, and form several spaces.
In the present embodiment, back segment crossbeam assembly comprises three crossbeams and four root posts, and wherein the length of first crossbeam 1, second cross beam 2, the 3rd crossbeam 3 reduces successively; First column 4 is identical with the second column 5 length, 3rd column 6 is identical with the 4th column 7 length, first column 4 and the second column 5 length are less than the 3rd column 6 and the 4th column 7 length, first column 4 and the second column 5 abut against and are arranged between first crossbeam 1 and second cross beam 2 together, 3rd column 6 is fixed on second cross beam 2 end and is fixedly connected with first crossbeam 1, and the 4th column 7 is parallel with the 3rd column 6 and be fixed on the end of first crossbeam 1; 3rd column 6 is fixedly connected with the 3rd crossbeam 3 with the 4th column 7 lower end.
Further, be fixedly connected with at least diagonal ligament 8 in second cross beam 2 lower end, diagonal ligament 8 is fixedly connected with bridge vehicle frame, can actv. dispersion column holding capacity.
Crossbeam and column are the rectangular tube of different size, can reduce the weight of crossbeam assembly, so that the light-weight design of crossbeam assembly.
As the distortion of crossbeam and longeron material, the material preparation that described crossbeam and longeron also can adopt other anti-deformations stronger, such as carbon fiber composite material and metal alloy compositions etc., under the utility model design, crossbeam and longeron material do not do concrete restriction.
In the present embodiment, different length crossbeam connects from the column of different length respectively, by the stress dispersion suffered by crossbeam and column in different crossbeams and column, avoid producing larger stress in a certain region and rupturing, substantially prolongs the service life of crossbeam assembly.Different crossbeams and column can mutually be strengthened and support, and reduce the possibility that crossbeam assembly is expanded laterally, make whole crossbeam assembly more stable and reliable.
Obviously, above-described embodiment is only for clearly example being described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of extending out or variation be still among the protection domain of the invention.
