Specific implementation mode
Below in conjunction with the accompanying drawings, the specific embodiment of cycle hub of the present invention is described in further detail.
As shown in the figure, the hub pipe 1 of cycle hub of the present invention, bolt 2, bearing 3, gear-box 4, end cap 5, sliding slot 6, very little
Set 7, brake disc 8, screw 9, shift fork 10, bearing block 11, wheel shaft 12, chain 13, driven tooth A14, worm tooth 15, drive shaft 16,
Gear A 17, spring 19, worm gear 20, worm gear shaft 21, telescopic rod 22, gear B 23, impeller 24, bolt 25, resets sliding part 18
Spring 26, flywheel 27, driven tooth B28, worm gear axle bed 29, guide groove 30, slot 31, inclined-plane 32, baffle ring 33, dog 34, convex key 35,
Screw hole 36, driving axle bed 37, buffer spring 38, adjusting rod 39, rocker stand 40, drag-line 41, Rocker arm 42, guide slot 43.
The both ends of wheel shaft are extend out to outside hub pipe end-cap, after the both ends of wheel shaft are fixed on the vehicle frame of bicycle, entire wheel hub
For assembly set on wheel shaft, hub pipe drives entire hub unit to be rotated around wheel shaft when rotating, have sliding part only and do not turn.
Embodiment 1
As shown in Figures 1 to 9, the cycle hub, bearing 3 are mounted on the bearing block 11 of gear-box 4, bearing 3
Internal diameter is sleeved on wheel shaft 12, and gear A, gear B are sleeved on wheel shaft 12 and can be rotated on wheel shaft 12, and sliding part 18 is sleeved on wheel shaft
It can slide axially and cannot be rotated on wheel shaft 12 on wheel shaft 12 on 12.
Drive shaft 16 is mounted in the driving axle bed 37 of gear-box 4, and gear A 17 and driven tooth A14 is driven with chain 13, tooth
B and driven tooth B engaged transmissions are taken turns, drive shaft 16 is equipped with worm tooth 15, worm tooth 15 and 20 engaged transmission of worm gear, 20 internal diameter of worm gear
Screw hole 36 is offered, is equipped with the telescopic rod 22 with thread in screw hole 36, telescopic rod 22 is fixedly connected with hub pipe 1,20 turns of worm gear
Telescopic rod 22 is stretched out or is shunk in worm gear shaft 21 under the action of screw thread when dynamic.
Control wheel shaft 12 is achieved like this in 1 position of hub pipe bias or rehabilitation center, and in vehicle wheel rotation, knob is drawn
41 Rocker arm 42 of rope is strained to push away adjusting rod 39 and sliding part 18 inside, the dog 34 on sliding part 18 with it is convex on gear 17A
Pawl 34 is mutually clamped, and the rotation of wheel hub at this time drives drive shaft 16 also and then to rotate, and the worm tooth 15 being located in drive shaft 16 is nibbled
It closes worm gear 20 to rotate backward, telescopic rod 22 is stretched under the action of screw thread from worm gear shaft 21 outward when worm gear 20 rotates, and is stretched
Contracting bar 22 stretch out while also drive hub pipe 1 and the wheelbase of wheel shaft 12 to pull open, the cooperation lower hub of guide slot 43 and end cap 5 not
Realize that wheel shaft 12 and hub pipe 1 are eccentric in the case of partially askew, the internal diameter of hub pipe 1 when wheel shaft 12 and hub pipe 1 eccentric certain position
Start top and arrive shift fork 10, because 10 jag section of shift fork, than relatively thin and be machined with inclined-plane 32, shift fork 10 forces top arrive impeller 24, pushes away
Moving part 24 overcomes the elastic force impeller 24 of buffer spring 38 to push up sliding part 18 and gear A 17 to separating, to real along slot 31
Existing sliding part 18 is automatically separated with gear B 23 to control being stopped for telescopic component, and gear A 17 is only empty around wheel shaft 12 at this time
Turn, drive shaft 16 and worm gear 20 are all stopped, and realize that wheel shaft 12 in the former setting eccentric position of hub pipe 1, makes bicycle running
State in fluctuating rough ride.
When knob loosens drag-line 41, sliding part 18 under the action of spring 19 top of sliding part 18 to another gear B 23 with
It engages, and gear B 23 and driven tooth B28 engaged transmissions, 15 engaging worm wheel 20 of worm tooth rotates forward, flexible when worm gear 20 rotates
Bar 22 is shunk back under the action of screw thread in worm gear shaft 21, and hub pipe 1 and wheel shaft 12 are also driven while telescopic rod 22 is shunk back
Wheelbase furthers, in hub pipe 1 with wheel shaft 12 close to concentric position when, the internal diameter of hub pipe 1 starts top and arrives another shift fork 10 because
For 10 jag section of shift fork than relatively thin and be machined with inclined-plane 32, shift fork 10 forces top arrive impeller 24, and impeller 24 overcomes spring 19
Elastic force impeller 24 pushes up sliding part 18 and gear B 23 to separating, to realize that sliding part 18 is automatic with gear B 23 along slot 31
Separation is stopped to control telescopic component, and gear B 23 only dallies around wheel shaft 12 at this time, and drive shaft 16 and worm gear 20 all stop work
Make, realizes that wheel shaft 12, in concentric position, makes bicycle be in the parallel state smoothly travelled with hub pipe 1.
It can thus be appreciated that being driven on same group of axis can be made with chain-driving another side direct geared engaged transmission on one side
Drive shaft rotates and reverse, and worm gear forward or reverse can make wheel shaft be in the bias and concentric of wheel hub.
Chain sprocket of the present invention can also use direct geared engagement to replace, and can equally reach drive shaft and rotate forward and anti-
Turn, the technique effect for making telescopic rod shrink and stretch out.
