The working principle of the gear of single wheel drive two fully-automatic gearbox is in the utility model：When one gear starting, wheel for inputting 5 is passed
Graduating power is to center driving axis 1, and since center driving axis 1 is fixedly connected with centre wheel 30, centre wheel 30 is rotated, centre wheel
30 impart power to planet carrier 32 by the transmission of planetary gear 31, planet carrier 32 and are set to 32 one end outer circumference surface of planet carrier
On the first ratchet 43 rotation, since the first ratchet 43 is meshed with the first pallet piece 41, and the first pallet piece 41 is set to
On pallet piece frame 40, pallet piece frame 40 is fixedly connected with wheel hub 2 again, therefore power is ultimately transferred to wheel hub 2 and is carried out by wheel hub 2
Power output, this process are the transmitting dynamic process that slows down, therefore low speed can be realized than starting, when second gear accelerates, the second pallet piece
The clump weight 421 of 42 one end is moved using pin as basic point along the direction far from axle center by the effect of centrifugal force, to make to be located at second
The pawl portion 4200 of 42 other end of pallet piece is moved to axis direction, so that the pawl portion 4200 of the second pallet piece 42 made is in
The second ratchet 44 on heart wheel 30 is meshed, and wheel for inputting 5 transmits power to center driving axis 1, due to center driving axis 1 and center
Wheel 30 is fixedly connected, therefore centre wheel 30 rotates, since the second ratchet 44 on centre wheel 30 is meshed with the second pallet piece 42,
Second pallet piece 42 is set on pallet piece frame 40 again, and pallet piece frame 40 is fixedly connected with wheel hub 2, therefore power final 1:1 passes
It passs wheel hub 2 and power output is carried out by wheel hub 2, when second gear, planet carrier 32 is in servo-actuated state.
In conclusion the speed changer in the utility model is by setting centrifugal ratchet part, it can be achieved that self shifter, reduces
Shift assembly, structure is simpler, and in addition the speed changer in the utility model can realize that low speed than starting, is ridden more easily, fastly
1 when speed gear:1 output, reduces the transmission of planetary transmission, has improved transmission efficiency.
