Abstract
The utility model provides an ideal folding speed variable and damping bicycle which belongs to the technical field of a bicycle. Compared with the prior art, a front and a rear bicycle frames are connected by hinges, which is convenient for folding; a drive part is provided with secondary speed variation, which enlarges speed variation ranges; a damping device is arranged between a front and a rear forks, which is favorable for eliminating vibration; thus, the folding speed variable and damping bicycle of the utility model has the advantages of compact structure, convenient folding, big speed variation ranges, good damping effect, light weight, practicality, etc.
Description
The utility model belongs to technical field of bicycles, is a kind of collapsible speed change damping bicycle.
Existing bicycle is single collapsible, or the one-level speed changing type, and complex structure uses inconvenience.
The purpose of this utility model is that design is a kind of simple in structure, compactness, collapsible speed change damping bicycle in light weight, convenient and practical.
The main technical schemes that the utility model is taked is that vehicle frame is made former and later two vehicle frames, and is middle with a hinge connection, forms fold mechanism; Between the axis of back vehicle frame and back fork two above change wheels are installed, a tension wheel forms speed-changing mechanism; Mounting shock absorber between preceding fork and back fork and back vehicle frame constitutes the collapsible speed change damping bicycle of the utility model.
The utility model is a technical field of bicycles, and a kind of desirable collapsible speed change damping bicycle is provided, and compared with prior art, connects owing to be provided with hinge in frame junction, front and back, and is folding easy; Owing to be provided with the two stage speed change chain-driving in the driving section, speed range is big; Owing between preceding fork and back fork and back vehicle frame, be provided with bumper, help eliminating vibrations, therefore, the collapsible speed change damping bicycle of the utility model has compact conformation, and is folding easy, speed range is big, good damping effect, remarkable advantages such as light practicality.
Now further specify the main art technical characterictic of the collapsible speed change damping bicycle of the utility model in conjunction with the accompanying drawings.
Fig. 1, collapsible speed change damping bicycle structural representation.
Fig. 2, collapsible speed change damping bicycle A are to structural representation.
Referring to Fig. 1, collapsible speed change damping bicycle structural representation, Fig. 2, collapsible speed change damping bicycle A is to structural representation, before, back vehicle frame 2 is connected with 4 usefulness hinges 3, bumper 5 is installed on the preceding fork, bumper 1 is installed in behind 2 kinds of the vehicle frames in back between the fork 9, back fork 9 is connected on the after-frame 2-1, is fixed with drive sprocket 6-3 on the axis 8, is fixed with speed change wheel shaft 10 on the back fork 9, speed change wheels 6-1,6-4 etc. are fixed on the speed change wheel shaft 10, and tension wheel 6-2 is fixed on the fork of back, constitutes the collapsible speed change damping bicycle of the utility model.
During use, the moving trailing wheel of back vent subband can rotate around back vehicle frame axis, so that the vibrations of trailing wheel are eliminated by bumper.
