Abstract
The utility model discloses a bicycle speeding-up driving wheel comprising a planetary gear drive mechanism, a wheel spoke, a wheel rim and a tire, wherein, the geared ring of the planetary gear drive mechanism is driven by a bicycle flywheel, and the planetary gear drive mechanism composes the wheel hub and the wheel spoke of the bicycle speeding-up driving wheel. The bicycle speeding-up driving wheel has the advantages that the wheel diameter of the bicycle is reduced, the transmission speed ratio is increased, the driving speed of the bicycle of which the wheel diameter is 12 inches is enabled to overpass the driving speed of the bicycle of which the wheel speed is 26 inches, the volume of the bicycle is reduced, the riding is labour-saving, and the carrying and the storing are more convenient, thereby being applicable to bicycles, tricycles, wheelchairs, scooters, electric bicycles, etc.
Description
Technical field
The utility model belongs to the bicycle quick field, particularly a kind of bicycle wheel inner speeding-up drive wheel that can make the bicycle speedup.
Background technology
Existing bicycle speedup driver train is spared outside wheel, makes that weight, volume and the speed of bicycle are all limited to, and gives using and depositing and make troubles of people.Make bicycle in light weight, volume is little, speed is fast, must on the size of the running part of bicycle and wheel, be improved.
Summary of the invention
Can not realize that in order to overcome existing bicycle quick bicycle is in light weight, volume is little and fireballing deficiency, the utility model adopts planetary gear mechanism to form the wheel hub and the spoke of bicycle quick, increase transmission speed ratio and made full use of the space segment in the wheel again, reduced the drive wheel diameter, actv. has overcome weight, volume and the contradiction between speed of bicycle.
The technical scheme that the utility model solves and technical matters adopted is: the planetary gear mechanism of bicycle wheel inner speeding-up drive wheel is to be the fixed part of one by wheel shaft and pinion carrier, is equipped with two on the pinion carrier with upper planetary gear; Having a planetary side that sun gear (wheel hub) and spoke, wheel rim and tire are housed is integral and is rotating element; The opposite side of pinion carrier is equipped with the gear ring frame that is fixed together with gear ring, on the gear ring frame sprocket wheel is housed, and each gear center is equipped with that bearing forms; Gear ring in the planetary gear mechanism is by chain wheel drive; Planetary gear mechanism has been formed the wheel hub and the spoke of bicycle wheel inner speeding-up drive wheel.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is a semisectional view of the present utility model;
Fig. 2 is a structural principle front view of the present utility model;
Fig. 3 is a structural principle cutaway view of the present utility model.
As shown in drawings: 1. tire, 2. wheel rim, 3. spoke, 4. gear ring, 5. pinion carrier, 6. planetary wheel, 7. sun gear, 8. sprocket wheel, 9. wheel shaft.
Specifically execute real mode
Planetary gear mechanism of the present utility model is to be the fixed part of one by wheel shaft (9) and pinion carrier (5), be equipped with two on the pinion carrier (5) with upper planetary gear (6), have a side of planetary wheel (6) that sun gear (7) (wheel hub) and spoke (3), wheel rim (2) and tire (1) are housed and be integral and be rotating element; The gear ring frame that the opposite side of pinion carrier (5) is equipped with and gear ring (4) is fixed together is equipped with sprocket wheel (8) on the gear ring frame, each gear center is equipped with that bearing forms.
Sprocket wheel (8) is rotated together by external force (chain) cw driven gear circle (4), driving sun gear (7), spoke (3), wheel rim (2) and tire (1) by planetary wheel (6) [pinion carrier (5) braking] rotates, thereby realize its wheel inner speeding-up transmission, this is a backward rotation; Make its forward rotation can apply opposite force and sprocket wheel (8).Perhaps, planetary wheel is made two-layer gear up and down.
Claims (3)
1, bicycle wheel inner speeding-up drive wheel is made up of planetary gear mechanism, spoke, wheel rim and tire, it is characterized in that: planetary gear mechanism is to be the fixed part of one by wheel shaft and pinion carrier, is equipped with two on the pinion carrier with upper planetary gear; Having a planetary side that sun gear wheel hub and spoke, wheel rim and tire are housed is integral and is rotating element; The opposite side of pinion carrier is equipped with the gear ring frame that is fixed together with gear ring, on the gear ring frame sprocket wheel is housed, and each gear center is equipped with that bearing forms.
2, bicycle wheel inner speeding-up drive wheel as claimed in claim 1 is characterized in that: the gear ring in the planetary gear mechanism is by chain wheel drive.
3, bicycle wheel inner speeding-up drive wheel as claimed in claim 1 or 2 is characterized in that: planetary gear mechanism has been formed the wheel hub and the spoke of bicycle wheel inner speeding-up drive wheel.
