Abstract
The utility model relates to a variable cross-section big-camber beam frame structure used for a bestriding motorcycle. The structure comprises a variable cross-section big-camber beam consisting of a front part, a middle part and a back part, wherein the variable cross-section big-camber beam has a dragon-boat shape, the front variable cross-section big-camber beam is respectively connected with a vertical pipe reinforcing plate from the left and the right sides thereof, and the vertical pipe reinforcing plate is connected with a vertical pipe and a middle beam; the tail part of the back variable cross-section big-camber beam directly passes through a cross beam II and is fixed with the cross beam II at the back end thereof; and the middle variable cross-section big-camber beam is fixedly connected with a cross beam I, and the tail part of the middle beam is also fixed with the cross beam I. The variable cross-section big-camber beam structure is adopted, formed at a time and welded integrally, thereby avoiding the uneven stress phenomenon after a rectangular pipe structure is bent. Furthermore, an entire portal girder adopts the variable cross-section structure and greatly solves the problem of uneven frame stress distributed at different parts, thereby prolonging the service life of the entire vehicle.
Description
Technical field:
The utility model relates to a kind of motorcycle frame structure that uses on motor tricycle, relate in particular to the big beam bending bicycle shelf structure of a kind of variable section that uses on the saddle ride type motor-tricycle.
Background technology:
At present, gantry beam of motor tricycle generally adopts the rectangular tube bending and molding, because under vehicle dead weight and loading condition, the stressed size of the diverse location of gantry beam is also different, simultaneously,, bends by rectangular tube because need rolling over multiple tracks, and in the bending process, the bending part can produce stress because of distortion, because inside and outside both sides deflection difference, the promptly inboard extruding outside stretches, thereby suffered stress difference, cause gantry beam internal stress branch inequality after the moulding, reduced the service life of car load.
Summary of the invention:
Generally adopt gantry beam vehicle frame of rectangular tube bending and molding at motor-tricycle, the purpose of this utility model is to provide a kind of steadiness that can strengthen car load according to the stressed different situations of vehicle frame, improve the vehicle load-carrying capacity, the big beam bending bicycle shelf structure of variable section of scientific and reasonable again materials, saving cost.
The technical solution of the utility model realizes in the following manner: comprise the big camber beam of being made up of front portion, middle part and rear portion three parts of the variable section that is connected the motor bike on the vehicle frame, it is characterized in that:
The profile of the big camber beam of variable section is the dragon boat shape, and its front camber beam sectional dimension is inequality,
The front structure of the big camber beam of variable section is: the big camber beam of variable section is connected with the standpipe brace panel from the left and right sides respectively, and the standpipe brace panel links together with standpipe and central sill again as reinforcement,
The rear structure of the big camber beam of variable section is: the big camber beam afterbody of variable section leads directly to crossbeam II, and the big camber beam of variable section is fixed together in rear end and crossbeam II,
The central structure of the big camber beam of variable section is: the big camber beam of variable section is captiveed joint with crossbeam I, and middle beam rear part is also captiveed joint with crossbeam I.
Middle beam rear part welds mutually with crossbeam I and is welded with brace panel in both sides, and top is welded with the saddle fixation frame.
Good effect of the present utility model is:
Owing to adopted the big camber beam structure of variable section, one-shot forming, integral solder, avoided the phenomenon of unbalanced stress after the bending of rectangular tube structure, and whole gantry beam adopts variable section structure, solved the problem of vehicle frame greatly, the service life of having improved car load in different parts stress distribution inequality.
And this later-model variable section gantry girder construction is considered car load exactly under strained condition, and the stressing conditions of different parts is different to design.The design of this variable section camber beam, also taken all factors into consideration the required special processing technology of its special cross-section, simultaneously in order to reduce the unrelieved stress of camber beam self, this camber beam adopts the particular manufacturing craft one-shot forming, integral solder, make its rigidity, intensity all improve the also all corresponding increase of the steadiness of car load, load-carrying capacity so greatly.
The big camber beam structure of motor tricycle variable section, be to introduce UG parametrization automobile design theory, adopt the difference of three-dimensional finite element analysis, the stressing conditions of simulating vehicle under full load dynamically, designed the big camber beam vehicle frame of variable section, adopt the particular manufacturing craft one-shot forming then, the big camber beam structure of the scientific and reasonable materials that integral solder forms.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the installing condition scheme drawing of structure of the present utility model on vehicle frame.
The specific embodiment:
Below in conjunction with accompanying drawing the technical solution of the utility model is further described:
As seen from Figure 1, variable section camber beam 4,5 is like a dragon boat, looks in the front, and the camber beam sectional dimension differs, from front to back according to stressing conditions change clocklike successively.
As seen from Figure 2, the connection of the big camber beam 4,5 of motor tricycle variable section on vehicle frame mainly is made up of front portion, middle part and rear portion three parts.
Anterior: the big camber beam 4,5 of variable section is connected with standpipe brace panel 3 from the left and right sides respectively, and 3 of standpipe brace panels are the reinforcements that standpipe 1 and central sill 2 link together, the front portion of car load combines by standpipe brace panel 3 handle risers 1, central sill 2, the big camber beam 4,5 of variable section like this, has improved the load-carrying capacity of vehicle.
The rear portion: big camber beam 4,5 afterbodys of variable section lead directly to crossbeam II7, make so the big camber beam 4,5 of variable section the rear end to fixing, simultaneously crossbeam II7 also two big camber beams organically in conjunction with as a whole, make complete vehicle structure more firm.
Middle part: big camber beam 4,5 of variable section and crossbeam I6 welding, and central sill 2 afterbodys also are welded with brace panel with crossbeam I6 welding and in both sides, top is welded with saddle fixation frame 8, several like this parts link together, two whole structures between the big camber beam of variable section were strengthened, also made the integraty of car load further get a promotion.
1, Applicable scope: this structure is applicable to the above motor tricycle product of the medium discharge capacity of 150ml ~ 250ml.
2, constructional feature: car load adopts UG parametrization automobile design theory, adopt the difference of three-dimensional finite element analysis, the stressing conditions of simulating vehicle under full load dynamically, designed the big camber beam vehicle frame of variable section, the big camber beam of this variable section adopts the particular manufacturing craft one-shot forming, integral solder, stiffness and strength is big, makes the steadiness of car load, load-carrying capacity all improve the safety factor height greatly.
