Embodiment
Below, with reference to accompanying drawing and embodiment, the present invention is described further, it is necessary to which explanation is, not
Under the premise of afoul, new implementation can be formed between various embodiments described below or between each technical characteristic in any combination
Example.
A kind of speed changer as Figure 1-3, including rotatably set rotating disk 10, rotatably set power transmission shaft 20,
Driving chain 30, transmission component 40, chain puller 50；Set successively along the direction away from its pivot center A1 on the rotating disk 10
It is equipped with some circle grooves 11；Each circle groove 11 includes multiple teeth of the pivot center A1 circumferential arrangements around rotating disk 10；The transmission
Component 40 includes from the inside to the outside socket and several relatively turnable drive links 41 successively；If several drive links 41 are with being somebody's turn to do
Dry circle groove 11 corresponds respectively；The first travelling gear 42 is respectively and fixedly provided with the drive link 41, is engaged with corresponding groove 11
The second travelling gear 43；Axis direction L of first travelling gear 42 along drive link 41 on several drive links 41 according to
Secondary linking；The central axis of the power transmission shaft 20 and the centerline axis parallel of drive link 41 and stagger；Pacify on the power transmission shaft 20
Equipped with can along power transmission shaft 20 axis direction slide and with the 3rd travelling gear 60 of the synchronous axial system of power transmission shaft 20；The transmission
Chain 30 is around being located on the 3rd travelling gear 60 and any one first travelling gear 42；The chain puller 50 is used for driving-chain
Axis direction of the bar 30 along drive link 41 is stirred.
When in use, the rotation of rotating disk 10 is passed through so that induced effect of each second travelling gear 43 in corresponding groove 11
Under rotated, and drive each drive link 41 is independent to rotate, now, each first travelling gear 42 is with 41 turns of drive link
It is dynamic, and the first travelling gear 42 for being transmitted the winding of chain 30 drives the 3rd travelling gear 60 to rotate by driving chain 30, with
Power transmission shaft 20 is driven to rotate.And stir axis direction of the driving chain 30 along drive link 41 by using chain puller 50,
Now, axis direction of the 3rd travelling gear 60 along power transmission shaft 20 is slided, and driving chain 30 can be made to switch to difference first and passed
On moving gear 42, the rotating speed of power transmission shaft 20 can be changed with this.The present invention by using rotating disk 10, power transmission shaft 20, driving chain 30,
The combination design of transmission component 40, chain puller 50, and by being set successively along the direction away from its pivot center in rotating disk 10
Some circle grooves 11 are equipped with, without gear is fixedly mounted on rotating disk 10, installation time can be saved, moreover, by that will pass
Dynamic component 40 is using socket and several relatively turnable drive links 41, and fixed on drive link 41 successively from the inside to the outside
There are the first travelling gear 42 and the second travelling gear 43, can make simple in construction, and be convenient to assemble, advantageously reduce cost；This
Outside, because axis direction of the first travelling gear 42 on several drive links 41 along drive link 41 is connected successively, chain is dialled
When device 50 is used to stir driving chain 30, the card chain of driving chain 30, the probability of de- chain can be also reduced.
Further, wherein one end of the drive link 41 is fixed with first travelling gear 42, and the other end is fixed with
Second travelling gear 43.And by using said structure, it can be convenient to make.
Further, the first travelling gear 42 on the drive link 41, the second travelling gear 43 and the corresponding structure of groove 11
As gear train, the number of teeth ÷ (numbers of teeth of the first travelling gear 42 of the second travelling gears of synthesis number of teeth ratio a=43 of gear train
The number of teeth of × correspondence groove 11), the synthesis number of teeth ratio a of each gear train is different.And due to the direct shadows of synthesis number of teeth ratio a
Gearratio is rung, by the way that the synthesis number of teeth ratio a of each gear train is arranged into different, the gearratio of each gear train can be made also different.
Further, the number of teeth of the second travelling gear 43 on each drive link 41 is with the ratio of the number of teeth of corresponding groove 11
One-level gear ratio b, the one-level gear ratio b of each gear train are different.
Further, the shape of each first travelling gear 42 is identical, and the shape of each second travelling gear 43 is identical, also
It is the diameter of each first travelling gear 42, number of teeth all same, the diameter of each second travelling gear 43, number of teeth all same, thus,
Only the number of teeth of each groove 11 need to be arranged to different, you can obtain different gearratios.
Further, the length of several drive links 41 is gradually shortened along orientation from the inside to the outside, it is,
The length of inner drive link 41 is longer than the length of outer drive link 41, to cause inner drive link 41 to be partly exposed to
Outside outer drive link 41, the fixation of the first travelling gear 42 and the second travelling gear 43 is convenient to.Wherein, in the present embodiment
In, the drive link 41 positioned at inner side is in solid cylindrical, and remaining drive link 41 is hollow cylindrical.
Wherein, the chain puller 50 can use any one existing chain puller on the market, as long as transmission can be stirred
Chain 30, such as derailleur can be used.
Specifically, be fixed with rotating disk 10 it is foot-operated, with when applying to bicycle, stepped on by user it is foot-operated, can band
Turn disk 10 rotates.
Further, the 3rd travelling gear 60 is sleeved on power transmission shaft 20, and is provided with along the axis side of power transmission shaft 20
To the groove 61 of extension, the lug boss 21 that is provided with the power transmission shaft 20 in embedded groove 61, so that the 3rd driving cog
Wheel 60 can along power transmission shaft 20 axis direction slide and with the synchronous axial system of power transmission shaft 20.And by using said structure, it can make
It must make relatively simple, conveniently.
The invention also discloses a kind of bicycle, has above-mentioned speed changer, and the bicycle includes car body, speed changer peace
On car body.Specifically, the rotating disk 10 of the speed changer is installed in rotation on car body；It is located at outside in transmission component 40
