Abstract
The utility model discloses a cross skeleton connecting joint for an aluminum alloy carriage. The cross skeleton connecting joint comprises a rectangular tubular fixing cylinders and eight connection boards vertically connected to the side wall of the fixing cylinders, connection boards on a same sidewall of the fixing cylinder are parallel to one another and form a slot. The upper end faces of the connection boards are flush with the upper end face of the fixing cylinder, and the lower end faces of the connection boards is transited to the sidewall of the fixing cylinder vertically fixed to the connection boards through arc segments. The integrally formed connecting joint realizes reliable connection between one support beam of a vehicle body skeleton of the aluminum alloy carriage and four floor beams, and tightly connects the support beam and the four floor beams. The cross skeleton connecting joint is high in strength and convenient for riveting, increase integral rigidity of the skeleton and is unlikely to be deformed.
Description
Technical field
The utility model belongs to bus body technical field, relates to bus body skeleton connection structure, specifically the jointing between a kind of support beam and floor bearer of aluminum alloy bus body skeleton.
Background technology
In recent years, along with deepening constantly that people are familiar with fuel oil crisis, promoted gradually energy conservation consciousness, automobile fuel ecomomy also starts to be taken seriously.The application of body lightening technology is an effective way that promotes automobile fuel ecomomy, and particularly car body of aluminum alloy technology has had significant progress.
At present, the domestic technical study that has had multiple producers to carry out aluminum alloy passenger vehicle, and had certain progress.The connection of aluminum alloy bus body skeleton mainly contains welding and rivets two kinds, Welded is compared to the welding of steel structure, and it is large that difficulty is wanted, and needs operating personal to grasp skilled welding technique, colleague is easily out of shape because the performance of aluminum alloy itself causes skeleton, is difficult for practical operation.Aluminum alloy riveting technology is more conducive to practical operation, but domestic car body of aluminum alloy skeleton technology is at the early-stage, aluminum alloy riveted joint level need to promote, and particularly the jointing between framework beam also needs continuous innovation, excavate quality lighter, connect riveted joint more reliably.
Adopting on the aluminum alloy bus body skeleton of riveting, between general vertical beam and crossbeam or vertical beam and longeron, employing " L " shape joint is connected, while connection for the framework beam that is criss-cross layout of a support beam and its upper end, general eight " L " shape jointings of needs connect, because these eight jointings are isolated mutually, not to be unified into an entirety, therefore the structural rigidity of joint area is poor, easily distortion, simultaneously riveting operation inconvenience.
Utility model content
For a support beam and its upper end in the aluminum alloy bus body skeleton of describing in background technology be criss-cross arrange framework beam between skeleton connectivity problem, the utility model proposes the aluminum alloy passenger vehicle cruciform skeleton jointing that a kind of structural strength is high, connection reliability is strong.
In order to achieve the above object, the aluminum alloy passenger vehicle cruciform skeleton jointing of the utility model design, comprises rectangular tubular stationary magazine creel, it is characterized in that: also comprise eight connecting panels, the vertical connection of sidewall of described eight connecting panels and described stationary magazine creel; Be positioned at connecting panel that same stationary magazine creel sidewall connects parallel and form draw-in groove; The upper surface of described connecting panel is concordant with the upper surface of stationary magazine creel, and the lower surface of described connecting panel transits to perpendicular stationary magazine creel sidewall by arc section.
Preferably, described stationary magazine creel and described connecting panel are one-body molded.
Preferably, on four of described stationary magazine creel sidewalls and described eight connecting panels, be equipped with riveted holes.
Further preferred, the riveted holes on four sidewalls of described stationary magazine creel is all linearly to arrange.
Further preferred again, the line of the riveted holes hole heart on described same stationary magazine creel sidewall is parallel to adjacent sidewall.
Further preferred, the riveted holes on described eight connecting panels is to be all S font to arrange.
Preferably, arc transition between described two adjacent connecting panels.
Preferably, arc transition between described connecting panel and stationary magazine creel sidewall.
The beneficial effects of the utility model are: integrated jointing can be realized the reliable connection between a support beam and four floor bearers in aluminum alloy bus body skeleton, a support beam and four floor bearers closely can be linked together, not only intensity is high, difficult deformation, riveting operation is convenient simultaneously, is conducive to promote the integral rigidity of skeleton.

In figure: stationary magazine creel 1, connecting panel 2, riveted holes 3, support beam 4, floor bearer 5, wherein: arc section 2.1.
Detailed description of the invention
As depicted in figs. 1 and 2, aluminum alloy passenger vehicle cruciform skeleton jointing, comprises rectangular tubular stationary magazine creel 1, and eight connecting panels 2, the vertical connection of sidewall of described eight connecting panels 2 and described stationary magazine creel 1; Be positioned at two connecting panels 2 that same stationary magazine creel 1 sidewall connects parallel and form draw-in groove; The upper surface of described connecting panel 2 is concordant with the upper surface of stationary magazine creel 1, and the lower surface of described connecting panel 2 transits to perpendicular stationary magazine creel 1 sidewall by arc section 2.1; Described stationary magazine creel 1 is one-body molded with described connecting panel 1, and the cross section of jointing is intersecting parallels.On four sidewalls of described stationary magazine creel 1 and described eight connecting panels 2, be equipped with riveted holes 3; Riveted holes 3 on 1 four sidewalls of described stationary magazine creel is all linearly to arrange, and the line of the hole heart of riveted holes 3 on described same stationary magazine creel sidewall is parallel to adjacent stationary magazine creel sidewall, and the riveted holes 3 on described eight connecting panels 2 is to be all S font to arrange.
Preferably, arc transition between described two adjacent connecting panels 2; Arc transition between described connecting panel 2 and stationary magazine creel 1 sidewall.
As shown in Figure 3, in the time carrying out skeleton connection, first the upper end of support beam 4 is inserted in the stationary magazine creel 1 of aluminum alloy passenger vehicle cruciform skeleton jointing, its upper surface is flushed with the upper surface of stationary magazine creel 1; Stationary magazine creel 1 and support beam 4 are riveted through the riveted holes on stationary magazine creel 1 sidewall with rivet again; Then respectively four floor bearers 5 are inserted in the middle of two parallel connecting panels 2, the upper surface of floor bearer 5 is flushed mutually, and the riveted holes that utilizes rivet to pass on connecting panel 2 are riveted floor bearer connecting panel; Like this, just realize being fixedly connected with between the floor bearer 5 that a vertical support beam 4 and four across distribute.
Certain described connecting panel 2 also in depth in the inner chamber of plate-girder 5, only needs suitably to adjust the size of connecting panel 2, can reach equally the purpose of this utility model, then this does not do tired stating.
