Description
Technical field
The utility model belongs to technical field of motorcycles, especially a kind of cross-country motorcycle vehicle frame of tubular structure.
Background technology
Traditional cross-country motorcycle vehicle frame such as Fig. 4, shown in Figure 5 are by head tube 1, go up girder pipe 2, component set-ups such as girder pipe 16, back cradle 17, support tube 18, back damping upper support seat 13 down.Wherein go up girder pipe 2 and be welded on the head tube 1 with following girder pipe 16, between through support tube 18 its intensity of reinforcement, back cradle 17 links to each other with girder pipe 2,3 up and down.This vehicle frame has only a underbeam pipe, and supporting construction is few, so integral intensity is bad, and poor seismic behavior.Because the structure more complicated of support tube 18, back cradle 17 so the material that whole vehicle frame expends is many, costs an arm and a leg.In addition, back damping upper support seat 13 directly is welded on the girder pipe 2, the back damping performance can not actv. have been given play in its position, simultaneously this kind bearing after subtract the bore deformation that causes easily in the motion process on the seat, and this structure frame requires the performance of the material that uses higher.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, and a kind of frame of motorcycle with two underbeams and a plurality of gusseted structures is provided, and makes whole frame of motorcycle be box structure, and not only consume material is few, and good integral strength, anti-seismic performance are strong.
The technical scheme that its technical matters that solves the utility model adopts is:
This frame of motorcycle, comprise head tube, be fixed with the girder pipe on the head tube, should go up the girder pipe and be provided with back damping upper support seat, left side side bar, following preceding right side side bar before the below of last girder pipe is provided with down, described preceding down left side side bar, following preceding right side side bar front end are fixed on the head tube, and its front end closes up, the rear end separates; The rear end of left side side bar, following preceding right side side bar is connected on left side, back side bar, right side, the back side bar down; The upper end of left side, described back side bar, right side, back side bar is fixed on the girder pipe, divides right and left and extend downwards in its lower end.Like this, unitized frame by one go up girder pipe and two following side bars, side bar is formed after two, integral body is box structure, not only consume material is few, and good integral strength, anti-seismic performance are strong.
Further, the lower end of left side, back side bar, right side, back side bar is connected with the chain stay installation sheet respectively, and the lower end of chain stay installation sheet is fixed with the driving engine bottom bracket.Be used for being connected with structures such as chain stay, driving engines.
Left side side bar, closing up between end and the last girder pipe of following preceding right side side bar are supported with first support tube, second support tube down, the lower end of first support tube, second support tube links together, and makes first support tube, second support tube and last girder pipe constitute a gusseted structure.Be supported with the 3rd support tube between side bar and left side, the back side bar on the left of preceding down, the 3rd support tube and following preceding left side side bar, gusseted structure of left side, back side bar formation; Be supported with the 4th support tube between preceding right side side bar and right side, the back side bar down, the 4th support tube is with preceding right side side bar, right side, back side bar constitute a gusseted structure down.Each support tube constitutes a plurality of gusseted structures, has increased the intensity of whole vehicle frame, has improved the anti-seismic performance of whole vehicle frame.
Be supported with connection pipe between left side, back side bar, right side, the back side bar.Like this, can further increase the intensity of whole vehicle frame.
Be connected with hanging beam on the driving engine between left side, back side bar, right side, the back side bar.Be used to connect driving engine.
The beneficial effects of the utility model mainly show: the utility model main body is made up of a upper beam and two underbeams, and is aided with many support tubes, makes whole vehicle frame be box structure, and not only consume material is few, and good integral strength, anti-seismic performance are strong.In addition, back damping upper support seat below has left side, back side bar, right side, back side bar to support, can change vehicle frame when jump is landed after the action direction of afterbody bounce, improved the comfort of navigating mate greatly.
