Abstract
The utility model relates to a bicycle flying wheel, which solves the problem that clockwise or counter clockwise pedaling enables the bicycle to move forward. A chain ratchet joint wheel composed of a chain wheel, a ratchet wheel A and an outer gear, and a tooth ratchet joint wheel composed of an inner gear and a ratchet wheel B, are respectively sheathed on the wheel shaft sleeves of the flying wheel in a sliding way; an intermediate wheel is arranged between the outer gear and the inner gear; the wheel shafts of the flying wheel are respectively provided with a ratchet pawl A engaged with the ratchet wheel A and a ratchet pawl B engaged with the ratchet wheel B; the utility model can be widely used in bicycles.
Description
The utility model relates to bicycle freewheel.
Bicycle generally all is that foot-operated direction is advanced now, does not have the function that foot-operated counter-rotation also can be advanced, and this just brings two shortcomings at least: the one, and as RV recreational vehicle, it is interesting not enough; The 2nd, it is not enough that the rider is reduced tired adjusting.Particularly run into a slope, against the wind, situation such as heavy duty, can not adapt to and drive.
The purpose of this utility model is exactly to provide a kind of positive and negative foot-operated Two speed flying wheel that bicycle is advanced for overcoming the above-mentioned shortcoming of bicycle.
The purpose of this utility model is achieved in that Two speed flying wheel, by the chain ratchet conjunctedly take turns, middle idle wheel, tooth papillae are conjunctedly taken turns, middle idle wheel hub discs, ratchet and flywheel axle sleeve etc. are formed, it is characterized in that the chain ratchet of being made up of sprocket wheel, ratchet first, external gear is conjuncted takes turns and by conjuncted wheel of tooth papillae that inner gear, ratchet second are formed, slides over separately on the flywheel axle sleeve; Idle wheel in the middle of between external gear and inner gear, being provided with; On the flywheel axle sleeve, be equipped with respectively with ratchet first ingear ratchet first, with ratchet second ingear ratchet second; And the ratchet of ratchet first, ratchet second is in the same way, and ratchet first, ratchet second is also in the same way.
Above-mentioned design, when sprocket wheel rotates forward, ratchet first and the engagement of ratchet first, driving wheel changes forward, and meanwhile, the effect of idle wheel turns round inner gear, ratchet second and the off-load of ratchet second in the middle of the mat; Otherwise when sprocket wheel rotates backward, ratchet first and the off-load of ratchet first, meanwhile, the effect of idle wheel is changeed inner gear forward in the middle of the mat, ratchet second and the engagement of ratchet second, also driving wheel changes forward; Then the same with existing flywheel during bicycle coasting, ratchet first, ratchet second all is in unloading condition.
Further specify again below by drawings and Examples.
Fig. 1 is the utility model basic structure scheme drawing.
Fig. 2 is the utility model STRUCTURE DECOMPOSITION scheme drawing.
Fig. 3 is the utility model flywheel axle sleeve scheme drawing.
Fig. 4 is the utility model assembling cross-sectional schematic.
Fig. 5 is Fig. 4 B-B view.
Fig. 6 is Fig. 4 A-A view.
Among the figure: chain stay behind 1 bicycle, 2 bicycle rear axles, 3 bicycle rears, 4 sprocket wheels, 5 ratchet first, 6 external gears, 7 middle idle wheels, 8 ratchet first, 9 flywheel axle sleeve, 10 inner geares, 11 ratchet second, 12 middle idle wheel hub discs, 13 left end caps, 14 balls, 15 middle idle wheel wheel shafts, 16Y shape plate, 17 right end caps, 18,19 ratchet springs, 20 ratchet second, 21 front plates, 22 rear plates, 23 back chain stay pipes.
As shown in the figure: middle idle wheel can all be established 2～6 at middle idle wheel hub discs upper edge circumference.Middle idle wheel is fixed on the chain stay pipe of back by the breast wheel hub discs.Accompanying drawing is the 1:1 view.The ratchet installation direction make it when bicycle pedals forward the time for advancing at utmost speed; When riding backward is ease ahead, but laborsaving.Ratchet and ratchet spring can adopt stock.The utility model structure and uncomplicated, easy to implement, install also very convenient, easy to utilize, the good DEVELOPMENT PROSPECT of tool.
Claims (2)
1, Two speed flying wheel, by the chain ratchet conjunctedly take turns, middle idle wheel, tooth papillae are conjunctedly taken turns, middle idle wheel hub discs, ratchet and flywheel axle sleeve etc. are formed, it is characterized in that the chain ratchet of being made up of sprocket wheel, ratchet first, external gear is conjuncted takes turns and by conjuncted wheel of tooth papillae that inner gear, ratchet second are formed, slides over separately on the flywheel axle sleeve; Idle wheel in the middle of between external gear and inner gear, being provided with; On the flywheel axle sleeve, be equipped with respectively with ratchet first ingear ratchet first, with ratchet second ingear ratchet second; And the ratchet of ratchet first, ratchet second is in the same way, and ratchet first, ratchet second is also in the same way.
2, Two speed flying wheel as claimed in claim 1, idle wheel can all be established 2～6 at middle idle wheel hub discs upper edge circumference in the middle of it is characterized in that.
