Abstract
The invention discloses a labor-saving gear-speed-governing bicycle comprising a frame. A saddle and a disc chuck are mounted on the frame, a gearbox is mounted on the frame and on the rear side of the disc chuck, two ends of an input shaft of the gearbox extend out of a shell of the gearbox respectively, pedals are mounted at two extending ends respectively, the right end of an output shaft of the gearbox extends out of the shell, and the disc chuck is fixed at the extending end of the output shaft. The labor-saving gear-speed-governing bicycle is simple in structure and reasonable in design, different revolving speeds of the bicycle is realized by shifting different positions from a slide gear to an output gear by a shifting fork, labor is greatly saved, transmission effect of the bicycle is improved, and riding is more labor saving and time saving.
Description
technical field:
The present invention relates generally to technical field of bicycles, relates in particular to a kind of powershift gear speed-regulating bicycle of economizing.
background technology:
Bicycle is because of its facility, energy-conserving and environment-protective, and useful traffic, can be used as again body-building apparatus, becomes indispensable instrument in people's daily life.Bicycle is according to the difference of its version, type of drive and speed regulating structure, can be divided into 16 vehicles, 18 vehicles, 20 vehicles, 22 vehicles, 24 vehicles, 26 vehicles, and floral disc axle and treadle axle in these bicycles is all same axle, adopt chain transmission and chain speed governing.But such transmission and mode of speed control, hindered the tractive performance of bicycle and driving efficiency and speed governing effect.
summary of the invention:
The object of the invention is exactly the defect in order to make up prior art, and a kind of powershift gear speed-regulating bicycle of economizing is provided, and it is good that it has tractive performance, and driving efficiency is high, the advantage of intensity and good rigidly.
The present invention is achieved by the following technical solutions:
A kind of powershift gear speed-regulating bicycle of economizing, include the vehicle frame of bicycle, vehicle seat, floral disc are installed on vehicle frame, it is characterized in that: the proceeds posterolateral that is positioned at floral disc on described vehicle frame is provided with change speed gear box, the housing external part outer and both sides that change speed gear box is stretched out respectively at the input shaft two ends of change speed gear box is separately installed with pedal, the output shaft right-hand member of change speed gear box stretches out outside housing, and described floral disc is fixed on the external part of described output shaft.
A kind of powershift gear speed-regulating bicycle of economizing, is characterized in that: described change speed gear box includes housing, in described housing, be rotatablely equipped with successively the input shaft, tween drive shaft and the output shaft that are parallel to each other, on described input shaft, fixed cover is equipped with driving gear; On tween drive shaft, fixed cover is equipped with intermediate gear, on tween drive shaft, be positioned at intermediate gear both sides respectively fixed cover transmission gear one and transmission gear two are housed; On described output shaft, be set with cliding gear, cliding gear is provided with the gear teeth one that can coordinate with transmission gear one and the gear teeth two that can coordinate with transmission gear two; The top that is positioned at output shaft on described housing is provided with declutch shift shaft, is set with and controls the shift fork that cliding gear slides on described declutch shift shaft.
A kind of powershift gear speed-regulating bicycle of economizing, is characterized in that: described housing is Al-alloy casing, and outer illiteracy of housing is equipped with swept-out umbrella cloth.
The present invention, by foot pedals, drives the input shaft in change speed gear box to rotate, and drives intermediate gear to rotate by driving gear on input shaft, and then, driven the rotation of transmission gear one and transmission gear two by tween drive shaft.Then, by shift fork, cliding gear is toggled it to the position needing, make transmission gear one and the gear teeth one engaged transmission, or make transmission gear two and gear two engaged transmission, finally drive floral disc to rotate by output shaft, bicycle moves ahead.
On described vehicle frame, be provided with and control the governor that shift fork moves, described governor is arranged on handle position.
Advantage of the present invention is:
The present invention is simple in structure, reasonable in design, stirs the diverse location of cliding gear to output gear by shift fork, has realized the different rotating speed of automatic vehicle, has greatly saved manpower, has increased the transmission effect of bicycle, rides more time saving and energy saving.
brief description of the drawings:
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of change speed gear box.
Fig. 3 is the structural representation of change speed gear box inside.
detailed description of the invention:
Referring to accompanying drawing.
