The operation principle of the portable gearshift multi-gear transmission device of Two-wheeled ratchet is in the utility model：The center passes
Moving axis 1 is power output member, and the speed change gear in the utility model realizes four-speed gear shift altogether, during bottom gear, pallet piece 21 and
One ratchet 22 is meshed, and power is inputted by power input shaft 4, because power input shaft 4 and pallet piece frame 20 are integrally formed, spine
Bluff piece 21 is installed on pallet piece frame 20, therefore the synchronous axial system of pallet piece 21, because pallet piece 21 is meshed with the first ratchet 22,
First ratchet 22 is integrally formed with the first gear ring 303 again, therefore the first gear ring 303 rotates, and the first gear ring 303 passes through the first planet
The transmission of wheel 302 imparts power to the first planet carrier 301, because the first planet carrier 301 and the second gear ring 313 are integrally formed,
Therefore the synchronous axial system of the second gear ring 313, the second gear ring 313 impart power to the second row by the transmission of the second planetary gear 312
Carrier 311, because the second planet carrier 311 is integrally formed with the 3rd gear ring 323, therefore the synchronous axial system of the 3rd gear ring 323, the 3rd tooth
Circle 323 imparts power to the third line carrier 321 by the transmission of the third line star-wheel 322, because the third line carrier 321 is with
Heart power transmission shaft 1 is fixedly connected, therefore the synchronous axial system of center driving axle 1, and enters action edge by the wheel at the both ends of center driving axle 1
Output.During two gears, mobile pallet piece frame 20, pallet piece 21 is disengaged from the first ratchet 22, and nibbled with the phase of the second ratchet 23
Close, power is inputted by power input shaft 4, and because power input shaft 4 and pallet piece frame 20 are integrally formed, pallet piece 21 is installed on again
On pallet piece frame 20, therefore the synchronous axial system of pallet piece 21, because pallet piece 21 is meshed with the second ratchet 23, the second ratchet 23 is again
It is integrally formed with the second gear ring 313, therefore the synchronous axial system of the second gear ring 313, the second gear ring 313 pass through the second planetary gear 312
Transmission imparts power to the second planet carrier 311, because the second planet carrier 311 is integrally formed with the 3rd gear ring 323, therefore the 3rd
The synchronous axial system of gear ring 323, the 3rd gear ring 323 impart power to the third line carrier 321 by the transmission of the third line star-wheel 322,
Because the third line carrier 321 is fixedly connected with center driving axle 1, therefore power is ultimately transferred to center driving axle 1 and by center
The wheel at the both ends of power transmission shaft 1 carries out power output.During three gears, mobile pallet piece frame 20, make pallet piece 21 and the phase of the second ratchet 23
Depart from, and be meshed with the 3rd ratchet 24, power is inputted by power input shaft 4, due to power input shaft 4 and pallet piece frame 20
It is integrally formed, pallet piece 21 is installed on pallet piece frame 20 again, therefore the synchronous axial system of pallet piece 21, due to pallet piece 21 and
Three ratchets 24 are meshed, and the 3rd ratchet 24 is integrally formed with the 3rd gear ring 323 again, therefore the synchronous axial system of the 3rd gear ring 323, and the 3rd
Gear ring 323 imparts power to the third line carrier 321 by the transmission of the third line star-wheel 322, due to the third line carrier 321 with
Center driving axle 1 is fixedly connected, therefore power is ultimately transferred to center driving axle 1 and entered by the wheel at the both ends of center driving axle 1
Action edge exports.During top gear, mobile pallet piece frame 20, pallet piece 21 is separated with the 3rd ratchet 24, and with the 4th ratchet
25 are meshed, because the 4th ratchet 25 is integrally formed with the third line carrier 321, therefore the synchronous axial system of the third line carrier 321, by
It is fixedly connected in the third line carrier 321 with center driving axle 1, therefore power is ultimately transferred to center driving axle 1 and passed by center
The wheel at the both ends of moving axis 1 carries out power output.
In summary, the portable gearshift multi-gear transmission device of Two-wheeled ratchet in the utility model is by traditional spline
Formula gearshift makes pawl type gearshift into, using not only compact-sized after pawl type gearshift, gearshift manipulation it is convenient and
And gearshift stability also greatly promotes, the pawl type gearshift in the utility model, which is also used as freewheel clutch, in addition makes
With without reusing freewheel clutch in planetary transmission, therefore enormously simplify structure.
The principle and its effect that the above embodiments only illustrative the utility model is created, and the reality that part uses
Example is applied, not for limitation the utility model；It should be pointed out that for the person of ordinary skill of the art, this is not being departed from
On the premise of utility model creates design, various modifications and improvements can be made, these belong to protection of the present utility model
Scope.
