The operation principle of multi gear automatic internal speed variator of real is in the present embodiment：First pawl 3010 of the freewheel clutch is
Normally open, i.e. the first pawl 3010 keep meshing state, the interior change in the present embodiment with the first ratchet 10 on flower-drum 1 always
Fast device realizes three transmission ranges altogether, and when low or first gear, power inputs to the second planet carrier 311 by power input 7, due to second
Planet carrier 311 and the first gear ring 302 are integrally formed, therefore drive the rotation of the first gear ring 302, pass through the biography of the first planetary gear 303
It is dynamic, drive first planet carrier 301 to rotate, due to the first pawl 3010 in first planet carrier 301 always with first on flower-drum 1
Ratchet 10 is meshed, therefore flower-drum 1 is driven to rotate, and realizes low or first gear, and after the speed of flower-drum 1 is brought up, first certainly on flower-drum 1
The clump weight end of pallet piece 400 generates centrifugal force in dynamic centrifugation gearshift 40, is moved along the direction far from axle center, in lever original
Under reason, the pawl end for being located at the other end is moved to axis direction, to make the pawl portion on pallet piece 400 and the second ratchet 402
It is meshed, the first pawl 3010 is servo-actuated state at this time, and power inputs to the second planet carrier 311 by power input 7, due to the
Two planet carriers 311 and the first gear ring 302 are integrally formed, and second ratchet 402 in 302 outside of the first gear ring and first automatically from
The pallet piece 400 of heart gearshift 40 is meshed, therefore power is exported from flower-drum 1, middle-grade speed change is realized, when the speed of flower-drum 1
When being increased to certain value again, the clump weight end of 41 pallet piece 410 of the second automatic centrifugation gearshift generates centrifugal force, along far from axis
The direction of the heart moves, to make the pawl on pallet piece 410 and the third ratchet 412 in 312 outside of the second gear ring be meshed, this
When, the first pawl 3010 and pallet piece 400 are servo-actuated state, and power inputs to the second planet carrier 311 by power input 7, the
Two planet carriers 311 deliver power to the second gear ring 312 by the transmission of the second planetary gear 313, due to the second gear ring 312 outside
The third ratchet 412 of side is meshed with the pallet piece 410 of the second automatic centrifugation gearshift 41, final power transmission to flower-drum 1,
Realize high-grade speed change.Internal speed changer can reduce the requirement to stepping on frequency in the present invention so that ride more easily, it is assumed that implement this
Slowest ratio in example is set as 2.25:1, the speed ratio of mid ranger and low or first gear is 1.5:1, the speed ratio of top gear and mid ranger is
1.5:1. the working speed that the pawl of the first automatic centrifugation mechanism 40 is opened is 90 revs/min, 41 pawl of the second automatic centrifugation mechanism
The working speed of opening is 135 revs/min.When so low-grade when input component input speed is 60 revs/min, the output speed of flower-drum
Degree is 40 revs/min, and when the input speed of input component mentions 135 revs/min, the output speed of flower-drum is 90 revs/min, at this time first
Automatic centrifugation gearshift 40 works, and the pawl portion on pallet piece 400 is meshed with the second ratchet 402, and the second planet carrier drives
Flower-drum exports, and realizes middle-grade speed change, and the rotating speed of the second planet carrier is 135 revs/min at this time, is much larger than the first automatic centrifugation mechanism 40
90 revs/min of working speed, allow input speed to be reduced to 90 revs/min or more from 135 revs/min, ensure the first automatic centrifuge
Structure 40 works normally, under 40 normal operating conditions of the first automatic centrifugation mechanism, when input speed is referring again to 135 revs/min,
The output rotating speed of that flower-drum is 135 revs/min, and the second automatic centrifugation gearshift 41 works at this time, the pawl portion on pallet piece 410
It is meshed with third ratchet 412, the second gear ring 313 drives flower-drum output, realizes high-grade speed change, and the rotating speed of the second gear ring is at this time
202.5 turns, it is much larger than 135 revs/min of the working speed of the second automatic centrifugation mechanism 41, input speed is allowed to be reduced from 135 revs/min
To 90 revs/min or more, ensure the second automatic centrifugation mechanism 41 normal work, therefore realizes middle-grade speed change and high-grade speed change post legged frequency
(trampling frequency) can reduce, so bicyclist can be made to ride more easily.

To make pallet piece 410 and the third ratchet 412 in the outside of the second gear ring 312 be meshed, the first pawl 3010 and pallet piece at this time
400 are in servo-actuated state, and power is inputted by first planet carrier 301, by the transmission of the first planetary gear 303, by power transmission
To the first gear ring 302, since the first gear ring 302 and the second planet carrier 311 are integrally formed, the second planet carrier 311 passes through the second row
The transmission of star-wheel 313 delivers power to the second gear ring 312 again, due to the second gear ring 312 and the second automatic centrifugation gearshift
41 pallet pieces 410 are meshed, and therefore, power is finally transferred to flower-drum 1 and carries out power output by flower-drum 1, realizes high-grade speed change.
Multi gear automatic internal speed variator of real in the present invention is compact-sized, easy for installation, transmission efficiency, firm, speed change of shifting gears
Stablize, different transmission ranges can be realized in the quantity by increasing and decreasing planetary transmission in flower-drum, and interior in the present invention
Speed changer is to realize automatic speed-changing by the principle of centrifugal force.The present invention by the way that centrifugal ratchet part is set in flower-drum,
To which the requirement to stepping on frequency can be reduced when gear is in high speed shelves.
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.
