The utlity model has following beneficial effect: 1) forward is stepped on to pedal or oppositely step on to pedal bicycle is advanced, and can change at any time to step in advancing and pedal the direction transformation motion sequence, and fatiguing one's body alleviates; 2) when line direction is stepped in change, change speed simultaneously and need not any operation; 3), in that oppositely step on when pedaling not only can walking along the street, and have both the effect of body-building according to the inverted order body-building principle; 4) forward is stepped on to pedal and oppositely step on to pedal and is hocketed, and changes plodding state, increases the enjoyment of walking along the street by bike.
Elaborate below in conjunction with accompanying drawing:
Fig. 1 is one of a utility model embodiment structural representation
Fig. 2 is two structural representations of the utility model embodiment
Embodiment one is for oppositely stepping on the transmission structures of pedaling deceleration.
Referring to Fig. 1, the utility model comprises rear axle 1 of the prior art, and is loaded on coro bearng 2, sprocket wheel 3 and the wheel hub 8 at rear axle two ends, and sprocket wheel 3 is fixed on the right drive gears 4.Right drive gears 4 is sleeved on the rear axle, and right ratchet 6 is housed on the cylindrical of right drive gears, and right ratchet 6 is fixed assembling with right ratchet 7 engagements, right ratchet 7 with wheel hub 8 by being threaded.Right ratchet 7 outer ends and right drive gears 4 matching parts are equipped with a circle steel ball 5.
Sun gear 9 is made of one the formula structure with right drive gears 4, also the detachable captive joint.Sun gear 9 meshes with the steamboat of planetary wheel 10, planetary bull wheel and internally toothed annulus 13 engagements.Planetary wheel carrier 11 movable sets are on rear axle, and planetary wheel 10 is contained on the planetary wheel carrier 11, and planetary wheel is generally 3-4.Bearing 12 is installed between internally toothed annulus 13 and the planetary wheel carrier 11.
Internally toothed annulus 13 is made of one formula with Left Drive shelves 14, also can be the split interconnection system.Left pawl 15 is housed on the cylindrical of Left Drive shelves 14, left pawl 15 and left ratchet 16 engagements, left ratchet 16 can be made of one formula with shelves lid 17, and left ratchet 16 is by being threaded and wheel hub 8 fixing assemblings.
Rear axle 1 is a hollow shaft, and a cylindrical void is opened at the middle part, and locating dowel pin 18 is housed in the cylindrical void, regulates bolt 19 and is through in the centre hole, and an end is connected with locating dowel pin 18, and the other end is connected with spanner on being installed in handlebar by backguy 21.Clutch tooth cover 22 and locating dowel pin 18 connect as one by Screw, and its end face tooth is meshed with the end face tooth of planetary wheel carrier 11 (A portion among Fig. 1), is set with retracing spring 20 on another side shaft of locating dowel pin 18.
Using method:
Forward is foot-operated: power transmission line is the right ratchet 7---of the right ratchet 6---of the right drive gears 4---of sprocket wheel 3---wheel hub 8.
Oppositely foot-operated: power transmission line is the right drive gears 4---of sprocket wheel 3---sun gear 9---planetary wheel 10---internally toothed annulus 13---Left Drive shelves 14---left pawl 15---left side ratchet 16---wheel hub 8.
Carry out forward: wheel hub 8 clockwise directions rotate, and left pawl all is sliding mode with left ratchet, right ratchet with right ratchet.
Retrodict backward: at this moment left pawl is with left ratchet engaged, and right ratchet retreats and is obstructed with right ratchet engaged.At this moment need with hand the handlebar upper ejector lever to be pinched earlier, backguy 21 drive adjusting bolts 19, locating dowel pin 18, clutch tooth cover 22 move to left together, clutch tooth cover 22 and planetary wheel carrier 11 jump out of mesh states, and planetary wheel carrier and rear axle are the state of being free to slide, and can fall back backward.Fall back stop after, unclamp spanner, backguy is loosened, and clutch tooth cover is connected with planetary wheel carrier is meshing again, bicycle returns to riding condition.
The foregoing description one structure then needs to do hub diameter very big very stupid as being used for reverse speedup, thereby as oppositely during speedup, then adopt the structure of embodiment two more suitable.
Referring to Fig. 2, compare with the structure of embodiment one, the two difference is: the big steamboat position reversed left to right of (1) planetary wheel 10, thereby cause internally toothed annulus 13, bearing 12, planetary wheel carrier 11 and sun gear about 9 transpositions, also corresponding change on the connection mode, be connected as a single entity (B portion is the bidentate occlusion portion among Fig. 2) by meshing mode by changing into right drive gears with Left Drive shelves integral structure as internally toothed annulus, sun gear was connected as a single entity to change into the Left Drive shelves with right drive gears originally and was connected as a single entity.(2) the car release portion of retrodicting changes another kind of mode, is promptly changed into by pushing left pawl by original release planetary wheel carrier 11, discharges left ratchet.Change increases clutch lasso 23 for removing clutch tooth cover 22 on the structure; Planetary wheel carrier 11 is keyed on the rear axle.
Because said structure changes, the also corresponding change of power transmission line, but total design is identical.
