Three pallet pieces 21 on pallet piece frame 20, the first ratchet 22 being arranged on the outer circumference surface of planet carrier 31 and it is arranged at centre wheel
The second ratchet 23 on 30, connected between second ratchet 23 and centre wheel 30 using tooth.Certainly in other embodiments
In, second ratchet 23 also directly can be integrally formed or be fixedly connected with center driving axle 1.The pallet piece frame 20 is in annulus
Shape is set, and several grooves 200 are offered on the pallet piece frame 20, and the pallet piece 21 is contained in the groove 200 and passed through
Pin is installed on pallet piece frame 20.The pallet piece frame 20 is integrally formed with power input shaft 4, and the pallet piece frame 20 is provided with
For controlling the elastic component of the initial position of pallet piece 21, in the present embodiment, the elastic component is spring, certainly in others
In embodiment, the elastic component is alternatively other elastic components such as torsion spring or flexure strip, the power input shaft 4 and stampede part
It is connected.
The operation principle of the portable gear of gearshift two speed change gear of Two-wheeled ratchet is in the utility model：The utility model
In center driving axle 1 be power output shaft, the speed change gear in the utility model realizes two gear speed changes altogether, during bottom gear, spine
Bluff piece 21 is meshed with the second ratchet 23, and power is inputted by power input shaft 4, due to power input shaft 4 and pallet piece frame 20 1
Body formed, pallet piece 21 is installed on pallet piece frame 20 again, therefore pallet piece 21 rotates, due to the ratchet 23 of pallet piece 21 and second
It is meshed, the second ratchet 23 is connected with centre wheel 30 by tooth again, and centre wheel 30 is integrally formed with center driving axle 1, therefore most
Drive center driving axle 1 to rotate eventually and carry out power output by being installed on the wheel at the both ends of center driving axle 1, during fast block,
Move axially pallet piece frame 20 so that the pallet piece 21 on pallet piece frame 20 is separated with the second ratchet 23, and with the first ratchet
22 are meshed, and 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 again
It is installed on pallet piece frame 20, therefore pallet piece 21 rotates, because pallet piece 21 is meshed with the first ratchet 22, the first ratchet 22
It is arranged on the outer circumference surface of planet carrier 31, therefore the run-in synchronism of planet carrier 31, planet carrier 31 will by the transmission of planetary gear 32
Power passes to centre wheel 30, and because centre wheel 30 and center driving axle 1 are integrally formed, therefore power is ultimately transferred to center biography
Moving axis 1 simultaneously carries out power output by the wheel at the both ends of center driving axle 1.
Embodiment 2
Gear speed change gear remaining structure of Two-wheeled gearshift two in the present embodiment is same as Example 1, difference
It is：In embodiment 1, planet carrier 31 is sheathed on center driving axle 1 and can relatively rotated relative to center driving axle 1,
Centre wheel 30 is integrally formed with center driving axle 1, and in the present embodiment, the planet carrier 31 is fixed with center driving axle 1
Connection, the centre wheel 30 are sheathed on center driving axle 1 and can relatively rotated relative to center driving axle 1.
Center driving axle 1 in the present embodiment is power output shaft, and the speed change gear in the utility model realizes two gears altogether
Speed change, during bottom gear, pallet piece 21 is meshed with the second ratchet 23, and power is inputted by power input shaft 4, due to power input shaft
4 are integrally formed with pallet piece frame 20, and pallet piece 21 is installed on pallet piece frame 20 again, therefore pallet piece 21 rotates, due to ratchet
Part 21 is meshed with the second ratchet 23, and the second ratchet 23 is connected with centre wheel 30 by tooth again, therefore the synchronous axial system of centre wheel 30,
Centre wheel 30 imparts power to planet carrier 31, therefore the run-in synchronism of planet carrier 31 by the transmission of planetary gear 32, due to planet
Frame 31 is fixedly connected with center driving axle 1, therefore power is ultimately transferred to center driving axle 1 and by the both ends of center driving axle 1
Wheel carry out power output.During fast block, axial movement pallet piece frame 20 so that pallet piece 21 on pallet piece frame 20 and the
Two ratchets 23 are separated, and are meshed with the first ratchet 22, and power is inputted by power input shaft 4, due to power input shaft 4 and spine
Bluff piece frame 20 is integrally formed, and pallet piece 21 is installed on pallet piece frame 20 again, therefore pallet piece 21 rotates, due to pallet piece 21 with
First ratchet 22 is meshed, and the first ratchet 22 is arranged on the outer circumference surface of planet carrier 31, therefore the run-in synchronism of planet carrier 31, by
It is fixedly connected in planet carrier 31 with center driving axle 1, therefore power is ultimately transferred to center driving axle 1 and by center driving axle
The wheel at 1 both ends carries out power output.It is that top gear planetary mechanism is servo-actuated the advantages of speed change gear in the present embodiment, without power
Loss, normally rides based on top gear, the fewer use of bottom gear.
In summary, the portable gearshift two of the Two-wheeled ratchet in the utility model keeps off speed change gear 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.
