【Embodiment】
Quick-mounting is become to a kind of gear of Two-wheeled ratchet movable type gearshift two of the present invention below by specific embodiment
Put and be described in further detail.
Embodiment 1
Join shown in Fig. 1 to Fig. 3, a kind of Two-wheeled ratchet movable type gearshift two keeps off speed change gear, including：Center driving axle
1st, gearshift 2, the planetary transmission 3 being installed on center driving axle 1 and the power input shaft being sheathed on center driving axle 1
4, the power input shaft 4 is connected with stampede part.
The planetary transmission 3 includes：Centre wheel 30, planet carrier 31, planetary gear 32 and gear ring 33, the centre wheel 30 with
Center driving axle 1 is integrally formed, and the gear ring 33 is mutually fixed with vehicle frame, and the gearshift 2 includes pallet piece frame 20, is installed on
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, is 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
Elastic component for controlling the initial position of pallet piece 21, in the present embodiment, the elastic component are 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 gear speed change gear of Two-wheeled ratchet movable type gearshift two is in the present invention：Center in the present invention
Power transmission shaft 1 is that the speed change gear in power output shaft, the present invention realizes two gear speed changes altogether, during bottom gear, pallet piece 21 and second
Ratchet 23 is meshed, and power is inputted by power input shaft 4, because power input shaft 4 is integrally formed with pallet piece frame 20, pallet piece
21 are installed on pallet piece frame 20 again, therefore pallet piece 21 rotates, because pallet piece 21 is meshed with the second ratchet 23, the second spine
Wheel 23 is connected with centre wheel 30 by tooth again, and centre wheel 30 is integrally formed with center driving axle 1, therefore finally drives center driving
Axle 1 rotates and carries out power output by the wheel for being installed on the two ends of center driving axle 1, during fast block, moves axially pallet piece
Frame 20 so that the pallet piece 21 on pallet piece frame 20 is separated with the second ratchet 23, and is meshed with the first ratchet 22, power by
Power input shaft 4 is inputted, because power input shaft 4 is integrally formed with pallet piece frame 20, and pallet piece 21 is installed on pallet piece frame again
On 20, therefore pallet piece 21 rotates, and because pallet piece 21 is meshed with the first ratchet 22, the first ratchet 22 is arranged at planet carrier 31
Outer circumference surface on, therefore the run-in synchronism of planet carrier 31, planet carrier 31 imparts power to center by the transmission of planetary gear 32
Wheel 30, because centre wheel 30 is integrally formed with center driving axle 1, therefore power is ultimately transferred to center driving axle 1 and in
The wheel at the two ends of heart power transmission shaft 1 carries out power output.
Embodiment 2
It is same as Example 1 that Two-wheeled gearshift two in the present embodiment keeps off speed change gear remaining structure, 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 is 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 that the speed change gear in power output shaft, the present invention realizes two gear speed changes altogether,
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 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
Second ratchet 23 is meshed, 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 impart power to planet carrier 31, therefore the run-in synchronism of planet carrier 31 by the transmission of planetary gear 32, due to planet carrier 31 with
Center driving axle 1 is fixedly connected, therefore power is ultimately transferred to center driving axle 1 and by the wheel at the two ends of center driving axle 1
Carry out power output.During fast block, axial movement pallet piece frame 20 so that the ratchet of pallet piece 21 and second on pallet piece frame 20
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 pallet piece frame
20 are integrally formed, and pallet piece 21 is installed on pallet piece frame 20 again, therefore pallet piece 21 rotates, due to the spine of pallet piece 21 and first
Wheel 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, 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 two ends of center driving axle 1
Wheel carry out power output.The advantage of speed change gear is that top gear planetary mechanism is servo-actuated in the present embodiment, without power attenuation,
Normally ride based on top gear, bottom gear is fewer to be used.
In summary, the Two-wheeled ratchet movable type gearshift two in the present invention keeps off speed change gear and changes traditional spline
Retaining device makes pawl type gearshift into, using not only compact conformation after pawl type gearshift, and gearshift manipulation is convenient and changes
Gear stability is also greatly promoted, and the pawl type gearshift in the present invention is also used as freewheel clutch and used in addition, and nothing
Freewheel clutch need to be reused in planetary transmission, therefore enormously simplify structure.
The principle and its effect of the above embodiments only illustrative the invention, and the implementation that part is used
Example, not for the limitation present invention；It should be pointed out that for the person of ordinary skill of the art, not departing from wound of the present invention
On the premise of making design, various modifications and improvements can be made, these belong to protection scope of the present invention.
