【Specific embodiment】
Two shift transmission of manual shift is inputted to a kind of centre wheel described in the utility model below by specific embodiment
It is described in further detail.
To join shown in Fig. 1 to Fig. 4, a kind of centre wheel inputs two shift transmission of manual shift, including：Power input 1, center
Transmission shaft 2, gearshift 3 and the planet speed change mechanism 4 being installed on center driving axis 2, the both ends point of the center driving axis 2
Wheel 5 is not installed, freewheel clutch 6 is equipped between 5 wheel hub of the center driving axis 2 and wheel.
The planet speed change mechanism 4 includes：Centre wheel 40, planet carrier 41, planetary gear 42 and gear ring 43, the power input
Part 1 is integrally formed with centre wheel 40, and the centre wheel 40 is sheathed on center driving axis 2 and can make compared with center driving axis 2
It relatively rotates, the gear ring 43 is fixedly connected with vehicle frame or damping is connected.
The gearshift 3 includes the first ratchet 30 being arranged on centre wheel 40, is arranged at 41 outer circumference surface of planet carrier
On the second ratchet 31, pallet piece frame 32 and at least one pallet piece 33 being installed on pallet piece frame 32, the pallet piece frame
32 are equipped with to control the elastic component of pallet piece initial position, and the elastic component can be spring, torsional spring or shrapnel.The spine
Several grooves 320 are offered on bluff piece frame 32, the pallet piece 33, which is contained in the groove 320 and passes through pin, is installed on pallet piece
On frame 32.First ratchet 30 is connected with centre wheel 40 by spline.Second ratchet 31 is integrally formed with planet carrier 41.
The pallet piece frame 32 is sheathed on center driving axis 2 and the axially movable company of radial positioning is formed between center driving axis 2
It connects, in the present embodiment, pallet piece frame 32 is connected with center driving axis 2 by spline.
The operation principle of centre wheel input two shift transmission of manual shift is in the utility model：Change in the utility model
Fast device realizes two gear speed changes altogether, and during bottom gear, pallet piece 33 is meshed with the second ratchet 31 being arranged on planet carrier 41, power
It is inputted by power input 1, since power input 1 and centre wheel 40 are integrally formed, centre wheel 40 rotates, centre wheel 40
By the transmission of planetary gear 42 planet carrier 41 is driven to rotate, due on the second ratchet 31 on planet carrier 41 and pallet piece frame 32
Pallet piece 33 is meshed, therefore pallet piece frame 32 rotates, since pallet piece frame 32 is connected with 2 radial positioning of center driving axis, because
This power is ultimately transferred to center driving axis 2 and carries out power output by center driving axis 2.During top gear, pawl is moved axially
Part frame 32 makes the pallet piece 33 on pallet piece frame 32 be disengaged from the second ratchet 31 on planet carrier 41, and and center driving
