Abstract
The invention discloses a welding reinforcing structure of the front portion of a motorcycle frame. The structure comprises a vertical tube and a diagonal bracing tube which are welded together. A reinforcing plate is connected outside the joint of the vertical tube and the diagonal bracing tube and composed of a U-shaped plate. The two edges of the upper end of the U-shaped plate extend upwards respectively to form supporting frames. The left edge of the U-shaped plate and the right edge of the U-shaped plate are welded to the diagonal bracing tube. The supporting frames are welded to the vertical tube. The front plate body of the U-shaped plate is provided with an installation hole. According to the structure, the reinforcing plate guarantees the strength of the front portion of the motorcycle frame, relative deflection of a part of the front portion will not occur even when the part is under stress, and therefore the vertical tube and the diagonal bracing tube can be welded together more firmly; the reinforcing plate has undergone edge folding treatment, and therefore the rigidity of the part is also improved; a horn can be installed in the installation hole of the front plate body; cooling air can flow through the space of the lower portion of the reinforcing plate smoothly.
Description
Technical field
The present invention relates to frame of motorcycle, refer more particularly to front part of motorcycle frame welding and strengthen structure.
Background technology
The standpipe of front part of motorcycle frame and the fixed form of down tube are at present: down tube is welded on standpipe, and the stiffening device that does not increase other is fixed, so, the weld of down tube and standpipe part when stressed can deflect in use, cause vehicle frame shakiness, easily leave potential safety hazard.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point of the prior art, provide a kind of simple in structure, weld firm, difficult drop-off, structure is strengthened in practical novel front part of motorcycle frame welding.
Structure is strengthened in front part of motorcycle frame welding provided by the invention, comprises standpipe, down tube, and described down tube welds mutually with standpipe; The outside of its standpipe and down tube junction is connected with brace panel; Described brace panel is made up of " U " shape plate, and described " U " both sides, shape plate upper end upwards extend to form respectively bracing frame; The right and left of described " U " shape plate welds mutually with down tube; Support frame as described above welds mutually with standpipe; The header board of described " U " shape plate is provided with mounting hole.
Adopted above structure, the present invention has following beneficial effect:
Front part of motorcycle frame welding of the present invention is strengthened structure and is adopted reinforcement structure, brace panel has guaranteed the intensity of vehicle frame front portion, make part that relative deflection can not occur when stressed, make the welding between standpipe and down tube more firm, brace panel has done crimp processing, the rigidity of part own also improves, and the mounting hole on header board can be installed loudspeaker, and it is smooth and easy that the space of brace panel bottom also makes cooling air pass through.
Accompanying drawing explanation
In order to be illustrated more clearly in the present invention, below will be to by reference to the accompanying drawings embodiment being briefly described.
Fig. 1 is the schematic diagram that structure is strengthened in front part of motorcycle frame welding of the present invention;
Fig. 2 is Fig. 1 left view.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
Referring to accompanying drawing 1,2, structure is strengthened in front part of motorcycle frame welding of the present invention, comprises standpipe 1, down tube 2, and described down tube 2 welds mutually with standpipe 1; Standpipe 1 is connected with brace panel 3 with the outside of down tube 2 junctions; Brace panel 3 is made up of " U " shape plate 4, and " U " shape plate 4 both sides, upper end upwards extend to form respectively bracing frame 5; The right and left of " U " shape plate 4 welds mutually with down tube 2, bracing frame 5 welds mutually with standpipe 1, both improved the intensity of part by the structure of brace panel 3, guarantee again the intensity of vehicle frame front portion, make part that relative deflection can not occur when stressed, make the welding between standpipe 1 and down tube 2 more firm; The header board of " U " shape plate 4 is provided with mounting hole 6, and mounting hole 6 can be installed loudspeaker, and it is smooth and easy that the space of " U " shape plate 4 bottoms also makes cooling air pass through.
Finally it should be noted that: above embodiment only, in order to technical scheme of the present invention to be described, is not intended to limit; Although the present invention is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
