Part 4 is connected with the first planet carrier 51 by tooth, during bottom gear, pallet piece 31 under the control of spring 301 with the phase of the 3rd ratchet 34
Engagement, power inputs by power input 4, because power input 4 is connected with the first planet carrier 51 by tooth, therefore the first row
The synchronous axial system of carrier 51, because the first planet carrier 51 and the second gear ring 63 are integrally formed, therefore the synchronous axial system of the second gear ring 63, the
Two gear rings 63 impart power to the second planet carrier 61 by the transmission of the second planetary gear 62, because the 3rd ratchet 34 is arranged at
On two planet carriers 61, the 3rd ratchet 34 is meshed with pallet piece 31 again, and pallet piece 31 is arranged on pallet piece frame 30 again, therefore spine
The synchronous axial system of bluff piece frame 30, due to being connected between pallet piece frame 30 and wheel hub 2 by guide rod 20 with arc groove 302, therefore it is dynamic
Power is ultimately transferred to wheel hub 2 and carries out power output by wheel hub 2；During middle speed gear, mobile pallet piece frame 30, makes pallet piece frame manually
Pallet piece 31 on 30 is disengaged from the 3rd ratchet 34, and is meshed with the second ratchet 33, and power is defeated by power input 4
Enter, because power input 4 is fixedly connected with the first planet carrier 51, the synchronous axial system of the first planet carrier 51, due to the first planet carrier
51 are integrally formed with the second gear ring 63, therefore the synchronous axial system of the second gear ring 63, because the second ratchet 33 is arranged at the second gear ring 63
On, the second ratchet 33 is meshed with pallet piece 31 again, and pallet piece 31 is arranged on pallet piece frame 30 again, therefore pallet piece frame 30 is same
Step rotates, and due to being connected between pallet piece frame 30 and wheel hub 2 by guide rod 20 with arc groove 302, therefore power finally transmits
Power output is carried out to wheel hub 2 and by wheel hub 2；During top gear, mobile pallet piece frame 30, makes the ratchet on pallet piece frame 30 manually
Part 31 is disengaged from the second ratchet 33, and is meshed with the first ratchet 32, and power is inputted by power input 4, due to power
Input component 4 is fixedly connected with the first planet carrier 51, therefore the synchronous axial system of the first planet carrier 51, and the first planet carrier 51 passes through the first row
The transmission of star-wheel 52 imparts power to the first gear ring 53, because the first ratchet 32 is arranged on the first gear ring 53, the first ratchet
32 are meshed with pallet piece 31 again, and pallet piece 31 is arranged on pallet piece frame 30 again, therefore the synchronous axial system of pallet piece frame 30, due to
Connected between pallet piece frame 30 and wheel hub 2 by guide rod 20 with arc groove 302, thus power be ultimately transferred to wheel hub 2 and by
Wheel hub 2 carries out power output.
