Abstract
The utility model relates to a speed gearing box for a bicycle, including a gear box shell which is internally provided with an input shaft, a central shaft, an output shaft and a bearing matched with the output shaft. The input shaft is fixed with a drive gear, the central shaft is fixedly provided with a driven gear and three transmission gears, and the output shaft is provided with three transmission gears in a sliding manner. The inside of the gear box shell is also provided with a fork pulling slide device and a gear propulsion or receding device which are connected with each other, wherein, the gear propulsion or receding device can slide on the output shaft. The utility model is simple in structure, good in speed change, has no pollution to the environment and is an ideal speed gearing box for a bicycle.
Description
One, technical field
The utility model relates to a kind of unpowered vehicle transmission system, relates in particular to a kind of derailleur.
Two, background technology
Ordinary bicycle is family's walking-replacing tool most popular on the Chinese consumption market all the time, existing more than 100 year history, but its maneuverability pattern constitutes with ancient and traditional device all the time, when running into big resistance, it is comparatively painstaking that the bicyclist generally feels, though Electrical Bicycle occurred on the market in recent years, but show according to pertinent data, the used battery of Electrical Bicycle in the market about 70% is a lead-acid battery, the 30%th, and cadmium brocade battery, and service life is generally shorter.The a large amount of old and useless battery of annual thus generation easily forms serious environmental and pollutes.It is reported that the insecurity of having travelled because of Electrical Bicycle in Beijing and the environmental pollution of old and useless battery have been completely forbidden Electrical Bicycle and set out on a journey.
Three, summary of the invention
It is a kind of pollution-free that the purpose of this utility model is to provide, and long service life is easy to operate, safety, the bicycle shift case apparatus that leicht fallen D/A and rate of travel can free conversion when riding.
The utility model is a kind of bicycle shift case apparatus, comprise gear-box case, input shaft is housed in gear-box case, tween drive shaft, the axle shaft reaches and input shaft, tween drive shaft, the block bearing that output shaft matches, input shaft tightens driving gear is housed, and tween drive shaft tightens ring gear and three transmission gears are housed, and slides on the output shaft transmission gear is housed, wherein driving gear and ring gear match, on the tween drive shaft each grade transmission gear can match with each grade transmission gear on the output shaft, and fork carriage and gear setback device also are housed in the gear-box case, and the fork carriage links to each other with gear setback device.
The fork carriage is by fork, the fork axle, form by the compression set that pellet shot from a slingshot and spring are formed, fork is provided with 3-5 lockhole and centre hole, gear setback device is by gear shifting device, and bolster reaches fixedly slide block composition, and bolster is fixed in the gear shifting device, fixedly slide block matches with centre hole, and gear shifting device can slide on output shaft.
Gear bar and gear line fixed mount are housed on the gear-box case outside face, gear bar one end links to each other with the fork axle, the other end links to each other with the gear spanner that is fixed in bicycle headstock by the gear line, and the output shaft outside links to each other with chain wheel, and the input shaft outside links to each other with the bicycle step.
After the utility model adopted said structure, its advantage was:
When 1, when bicycle running, needing speed change, stir the gear spanner, drive gear bar, fork axle, the fork axle makes the fork sway, and then promotion gear shifting device sway, make each grade transmission gear of output shaft carry out different gears as required than transmission, thereby reach the purpose of speed change with each grade transmission gear of center shaft.
When transmission gear in the middle of 2, the effect of compression set is on the axle and the transmission gear on the output shaft carry out gear transmission, it is mobile that effect by lockhole and compression set no longer produces fork, thereby make and do not carry out gear-driven transmission gear on the output shaft and block no longer mobile, avoid producing " connecting shelves " phenomenon, damage transmission gear.

Five, the specific embodiment
The utility model is the bicycle shift case apparatus, comprise gear-box case 1, input shaft 2 is housed in the gear-box case 1, tween drive shaft 3, axle shaft 4 reaches and input shaft 2 tween drive shaft 3, the block bearing 2A that output shaft 4 matches, 3A, 4A, input shaft 2 tighten driving gear 5 are housed, tween drive shaft 3 tightens ring gear 6 and transmission gear 7 is housed, 8,9, slide on the output shaft 4 transmission gear 10 is housed, 11,12, wherein driving gear 5 matches with ring gear 6, and transmission gear 7 can match with transmission gear 10, transmission gear 8 can match with transmission gear 11, transmission gear 9 can match with transmission gear 12, and fork carriage 13 and gear setback device 14 also are housed in the gear-box case 1, and fork carriage 13 links to each other with gear setback device 14
During installation, the utility model is fixedly installed in the bicycle stance, gear spanner 25 is fixed in the bicycle headstock place, link to each other with gear bar 23 by gear line 24, chain wheel 26 links to each other with the flywheel 29 at bicycle rear place by chain 28 and gets final product.
Bicycle running, when the needs speed change, pull gear spanner 25, drive gear bar 23, fork axle 16, fork axle 16 drives fork 15 sway, and then drives gear shifting device 20 sway, the transmission gear 7 that gear shifting device 20 promotes on the output shaft 4, transmission gear 8, transmission gear 10 on transmission gear 9 and the center shaft, transmission gear 11, transmission gear 12 produces different gear multiplications as required, thereby reach the purpose of speed change, by chain wheel 26, the transmission of chain 28 and flywheel 29 makes bicycle produce different moving velocitys at last.
