The operation principle of three-step gear shift driving device is in the present invention：First detent mechanism, 3010 and second pawl machine
The original state of structure 3030 is to be closed, i.e. the first detent mechanism 3010 is separated with the first ratchet 20, the second detent mechanism
3030 are separated with the second ratchet 21, and the third detent mechanism 3110 is normally open, i.e., third detent mechanism 3110 is always
Meshing state is kept with third ratchet 22, when work, transmission shaft 1 rotates, and drives the rotation of the second planet carrier 311, passes through third spine
Pawl mechanism 3110 is engaged with third ratchet 22, and wheel hub 2 rotates, and realizes level-one speed change, when needing to realize two stage speed change, by the
One shifting sleeve 32 moves from right to left, and when being moved to certain position, the tail portion of the first detent mechanism 3010 is contained in the first shift
In the annular groove 320 of set 32, the head of the first detent mechanism 3010 is opened, to make the first detent mechanism 3010 and the first spine
Wheel 20 is meshed, and the rotation of transmission shaft 1 drives the rotation of the second planet carrier 311, passes through the second planetary gear 312 and the second centre wheel
310 engaged transmissions drive the rotation of the second centre wheel 310, since the second centre wheel 310 is fixedly connected or one with the first gear ring 303
Body formed, the first gear ring 303 operates synchronously, and by 302 engaged transmission of the first gear ring 303 and the first planetary gear, drives the first row
Carrier 301 rotates, since the first detent mechanism 3010 in first planet carrier 301 is meshed with the first ratchet 20 on wheel hub 2,
Therefore, band runner hub 2 rotates, and realizes two stage speed change, when two stage speed change, since the rotating speed of the first detent mechanism 3010 is more than third
The rotating speed of detent mechanism 3110, therefore third detent mechanism 3110 is servo-actuated.When needing to realize three-step gear shift, by the first shifting sleeve
32 continue to move from right to left, and in the process of moving, the pawl tail portion of the first detent mechanism will no longer be contained in the first shift
In the annular groove of set, the first detent mechanism will become closed state by opening state, pass through the effect of STATEMENT OF FEDERALLY SPONSORED 36, the second shift
Set 34 can be moved and then from right to left, and with the movement of the second shifting sleeve 34, the tail portion of the second detent mechanism 3030 is flicked, and is made
The head for obtaining the second detent mechanism 3030 is opened, to make the second detent mechanism 3030 be meshed with the second ratchet 21, transmission shaft 1
Rotation drives the rotation of the second planet carrier 311, by 310 engaged transmission of the second planetary gear 312 and the second centre wheel, drives second
Centre wheel 310 rotates, since the second centre wheel 310 is integrally formed or is fixedly connected with the first gear ring 303, the first gear ring
303 and then rotate, since the second detent mechanism 3030 on the first gear ring 303 is meshed with the second ratchet 21 on wheel hub 2, because
This wheel hub 2 and then rotates, and realizes three-step gear shift, since the rotating speed of the second detent mechanism 3030 is more than third pawl when three-step gear shift
The rotating speed of mechanism 3110, therefore third detent mechanism 3110 is servo-actuated.
In conclusion bicycle use three-step gear shift driving device structure in the present invention is compact, easy for installation, transmission efficiency
Height, shift are firm, by the way that two sets of planetary transmissions are arranged in wheel hub, to realize three-step gear shift.
The principles and effects of the invention are only illustrated in the above embodiments, and the implementation that part uses
Example, and is not intended to limit the present invention；It should be pointed out that for those of ordinary skill in the art, not departing from wound of the present invention
Under the premise of making design, various modifications and improvements can be made, these are all within the scope of protection of the present invention.
