Abstract
The utility model discloses an integral cargo vehicle frame beam assembly, including two crossbeam bodies, crossbeam body middle part cross -section is pi shape, and pi shape both sides respectively are equipped with one row of rivet hole, and crossbeam body middle part is equipped with the lightening hole, and its both ends are vertical plane turn -ups, are equipped with the connecting hole on the turn -ups, and the notch of two crossbeam bodies is aimed at the back each other and is in the same place through rivet connection, forms the rectangular cross section girder construction of remaining silent. The utility model discloses a whole metal forming of steel sheet, smooth transition in the middle of and has reduced the stress concentration point, therefore intensity and reliability are higher, two rectangular beams of remaining silent that the crossbeam body is formed are compared and have been improved the torsional rigidity greatly in the open slot ellbeam, there is the lightening hole on the crossbeam body, light in weight, the turn down rims hole pitch in crossbeam body both ends is the fixed value, has the advantage that the commonality is strong.
Description
Technical field
The utility model relates to a kind of cargo vehicle frame crossbeam assembly, belongs to technical field of automobile parts.
Background technology
The cross-beam body of general cargo vehicle frame crossbeam is flute profile, both sides are designed with cross-beam connecting plate, adopt rivet on cross-beam body, because goods carrying vehicle applying working condition is complicated severe, cross member of frame assembly easily occurs in the junction of cross-beam connecting plate and cross-beam body that stress is concentrated and cracks, and on the other hand, cross-beam body cross sectional shape is opening trough_like, because the torsional stiffness of opening section is far below the torsional stiffness in cross section of remaining silent, so the torsional property of channel crossbar body is lower.
Summary of the invention
Technical problem to be solved in the utility model is the defect for prior art, provides a kind of lightweight, integral type cargo vehicle frame crossbeam assembly that torsional property is good.
For solving this technical matters, the utility model provides a kind of integral type cargo vehicle frame crossbeam assembly, comprise two pieces cross-beam body, in the middle part of described cross-beam body, cross section is π shape, and π shape both sides are respectively provided with row's rivet hole, are provided with lightening hole in the middle part of cross-beam body, its two ends are vertical plane flange, flange is provided with connecting bore, and the notch of two pieces cross-beam body by rivet interlacement together, forms square-section girder construction of remaining silent after mutually aiming at.
The length of described cross-beam body two ends flange is generally greater than the width of middle part π ellbeam.
Described cross-beam body, by the overall drawing of steel plate, seamlessly transits between middle part π ellbeam and two ends flange.
Beneficial effect: the utility model is the overall drawing of steel plate, and middle transition is level and smooth, decreases focal point of stress, thus intensity and reliability higher; The rectangular beam of remaining silent of two pieces cross-beam body composition, substantially increases torsional stiffness compared to open slot ellbeam; Cross-beam body there is lightening hole, lightweight; The pitch of holes of cross-beam body two ends flange is fixed value, has the advantage of highly versatile.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is specifically described.
Figure 1 shows that structural representation of the present utility model.
Fig. 2 a is depicted as structural representation front view of the present utility model.
Fig. 2 b is depicted as structural representation lateral plan of the present utility model.
Fig. 2 c is depicted as structural representation birds-eye view of the present utility model.
The utility model comprises two pieces cross-beam body 1, and two pieces cross-beam body 1 is linked together by rivet 2.
In the middle part of described cross-beam body 1, cross section is π shape, and π shape both sides are respectively provided with row's rivet hole, are provided with lightening hole 6 in the middle part of cross-beam body 1.
Described cross-beam body 1 two ends are vertical plane flange 7, and flange 7 is provided with connecting bore 8 and is used for being connected with chassis side rail.
The length of described cross-beam body 1 two ends flange 7 is generally greater than the width of middle part π ellbeam.
Connecting bore 8 spacing of described cross-beam body 1 two ends flange 7 is fixed values, improves the commonality of crossbeam assembly 3.
Described cross-beam body 1, by the overall drawing of steel plate, seamlessly transits between middle part π ellbeam and two ends flange 7.
The notch of two pieces cross-beam body 1 is linked together by rivet 2 after mutually aiming at, and form square-section girder construction of remaining silent, its torsional stiffness cuts section bar compared to opening trough_like and significantly improves.
Figure 3 shows that assembling schematic diagram of the present utility model.
Described crossbeam assembly 3 is fixed in the groove of left and right chassis side rail 4 with connector 5 (bolt or rivet) by the connecting bore 8 on flange 7.
The utility model integral type goods carrying vehicle cross-beam body is the overall drawing of steel plate, and middle transition is level and smooth, decreases focal point of stress, thus intensity and reliability higher; The rectangular beam of remaining silent that crossbeam assembly is made up of two pieces cross-beam body, substantially increases torsional stiffness compared to open slot ellbeam; Cross-beam body there is lightening hole, lightweight; The pitch of holes of cross-beam body two ends flange is fixed value, has the advantage of highly versatile.
The above-mentioned embodiment of the utility model, just casehistory, is not only, and all changes within the scope of the utility model or in equivalent scope of the present utility model are all surrounded by the utility model.
