Fig. 1 is the overall structure diagram of the body construction for the straddle-type single-track vehicle that the utility model embodiment provides；
Fig. 2 is the schematic cross-sectional view of the body construction for the straddle-type single-track vehicle that the utility model embodiment provides.
In figure 1 above and Fig. 2,
Roof 1, side wall 2, chassis 3, headwall 4, headstock 5.
Specific implementation mode
The core of the utility model is to provide a kind of body construction of straddle-type single-track vehicle, to simplify setting for body construction
Meter, while improving the intensity of body construction.
In order to make those skilled in the art more fully understand technical solution provided by the utility model, below in conjunction with attached
The utility model is described in further detail with specific embodiment for figure.
As depicted in figs. 1 and 2, a kind of body construction for straddle-type single-track vehicle that the utility model embodiment provides, packet
Car body ontology is included, car body ontology includes roof 1, side wall 2, chassis 3 and headwall 4, and roof 1, side wall 2, chassis 3 and headwall 4 are
Hollow double surface large aluminum alloy extrudates are welded.
The body construction of above-mentioned straddle-type single-track vehicle, it is hollow double by the way that roof, side wall, chassis and headwall to be both designed as
Surface large aluminum alloy extrudate is welded, and enormously simplifies the design of body construction, while improving body construction
Intensity.
What needs to be explained here is that hollow double surface large aluminum alloy extrudate sheets are as a kind of existing aluminium alloy material
Material has the characteristics that easily processed into type and intensity is high.
In some specifically embodiment, it is welded as stirring between above-mentioned hollow double surface large aluminum alloy extrudates
Mix friction welding (FW).Because agitating friction welding technology is a new welding technique at home.This technology connects in aluminum alloy bodywork
The field advantage of connecing is more prominent, is mainly manifested in：Weld seam zero-fault, there is no stomata, loose, air-tightness and watertightnesses in weld seam
By force；Environmental pollution is small, and weld seam thermal deformation is small, and thermal stress is small, and face of weld is smooth, and tensile strength and fatigue strength significantly carry
Height reduces car body weight, preferably ensures the advantages that service life of aluminum alloy bodywork.Of course, it should be understood that above-mentioned stir
It is only the utility model embodiment for the citing being welded to connect between closed type aluminium alloy extrusions to mix friction welding (FW), be can also be
Other common welding manners of those skilled in the art.
In addition, above-mentioned hollow double surface large aluminum alloy extrudates are silent aluminium alloy extrusions, because closed type aluminium closes
There are metal type material itself stronger strength and stiffness, service life interior energy to bear the effect of normal load without generating permanent deformation
And fatigue damage, possess longer service life, and then above-mentioned end wall structure not only simplifies the design of end wall structure, carries simultaneously
The high intensity of end wall structure.
In some more particular embodiments, the doorway of above-mentioned headwall 4 is moon gate.By being designed to moon gate, make
The door at headwall position is obtained, moulding is more beautiful rationally.Of course, it should be understood that above-mentioned moon gate is only that this practicality is new
Type embodiment can also be the design requirement according to vehicle for the preferable examples of doorway shape, select corresponding other shapes
Doorway.In addition, the moon gate can carry out cutting to doorway after completing using headwall to be made, can also be end
Corresponding shape is just had been processed into before each component splicing of the closed type aluminium alloy extrusions of wall ontology, is shape after the completion of splicing
At corresponding moon gate shape.
In addition, to ensure that each position stabilization welds together between car body, above-mentioned hollow double surface large aluminum alloys squeeze
The welding position of proximate matter is both provided with welding groove.
In more particular embodiment, above-mentioned car body ontology further includes headstock 5, and the shape of the headstock 5 is snakehead shape.It is logical
Cross and the shape of headstock be designed to snakehead shape, can not only reduce windage, and appearance compare before train nose shape it is beautiful
Degree is improved significantly, and the window of headstock is round using science fiction, and progress increases the presentation quality of headstock.
In some more specifical embodiments, the length of above-mentioned headstock 5 is 13560mm, width 3093mm, height
For 2424mm.Of course, it should be understood that the length of above-mentioned headstock, width and height are only the excellent of the utility model embodiment
Example is elected, other corresponding length, width and height values can also be selected according to specific vehicle and design requirement.
The body construction of straddle-type single-track vehicle provided by the utility model is described in detail above.It needs
