One driving wheel 20 is set on power output shaft 2 and is connect between power output shaft 2 by freewheel clutch 23, accelerates shift
When, the revolving speed of power output shaft 2 is higher than the revolving speed of the first driving wheel 20, and freewheel clutch 23 keeps the first driving wheel 20 and power defeated
Shaft 2 surmount it is servo-actuated, with realize accelerate shift.The driving member 21 is sheathed on power output shaft 2 and can be defeated relative to power
Shaft 2 rotates.The automatic centrifugation gearshift 22 includes: pallet piece frame 220,221, two, ratchet pallet piece 222, two connection
Moving part 223 and torsional spring 224 for controlling 222 initial position of pallet piece, the torsional spring 224 are mounted on pallet piece frame by pin
On 220, one end and the pallet piece frame 220 of the torsional spring 224 are abutted against, and the other end and the pallet piece 222 of the torsional spring 224 offset
It connects.The pallet piece frame 220 is fixedly connected with power output shaft 2, and the pallet piece 222 is installed on pallet piece frame 220 by pin
Above to make pallet piece 222 that can swing relative to pallet piece frame 220, the pallet piece 222 includes pawl portion 2220, interconnecting piece
2221 and counterweight part 2222, it is fixedly connected between 2222 three of the pawl portion 2220, interconnecting piece 2221 and counterweight part, in this reality
It applies in mode, the pin hole 2223 matched with pin is set in pawl portion 2220, and the STATEMENT OF FEDERALLY SPONSORED 223 is balancing pull rod, described
One end of balancing pull rod is connected with the interconnecting piece 2221 of one of pallet piece 222, the other end of the balancing pull rod with it is another
The interconnecting piece 2221 of a pallet piece 222 is connected, and the ratchet 221 is set on the outer circumference surface of driving member 21, and the power is defeated
Enter part 1 to be fixedly connected with driving member 21 or connect by freewheel clutch, in the present embodiment, the power input 1 with
Driving member 21 is achieved a fixed connection by spline, and the driving member 21 is equipped with the second driving wheel 210, second driving wheel
210 are achieved a fixed connection with driving member 21 by spline, and the transmission shaft 4 is equipped with third driving wheel 40 and the 4th driving wheel
41, the third driving wheel 40, the 4th driving wheel 41 are achieved a fixed connection between transmission shaft 4 by spline respectively, and described
One driving wheel 20 and the 4th driving wheel 41 form one group of low speed rotation pair, second driving wheel 210 with 40 groups of third driving wheel
At one group of high-speed drive pair, in the present embodiment, between first driving wheel 20 and power output shaft 2, the second driving wheel
Between 210 and driving member 21, four positions between third driving wheel 40 and transmission shaft 4 and between the 4th driving wheel 41 and transmission shaft 4
In setting, freewheel clutch is provided with only between the first driving wheel 20 and power output shaft 2, excess-three is all made of at position

The utility model is realized, as long as guaranteeing to be provided with freewheel clutch at least one position in four positions.
In the present embodiment, first driving wheel 20, the second driving wheel 210, third driving wheel 40 and the 4th transmission
Wheel 41 is gear, certainly in other implementations, first driving wheel 20, the second driving wheel 210, third driving wheel
40 and the 4th driving wheel 41 can also be sprocket wheel or belt wheel, when for sprocket wheel or belt wheel, first driving wheel 20 and the 4th is driven
By chain or transmission V belt translation between wheel 41, pass through chain or biography between second driving wheel 210 and third driving wheel 40
Dynamic V belt translation,
Two-wheeled two keeps off the working principle of full-automatic speed-changing device in the utility model are as follows: when bottom gear, power is by moving
Power output 1 inputs, to drive driving member 21 and the second driving wheel 210 to rotate, since the second driving wheel 210 is driven with third
Wheel 40 is meshed, therefore drives third driving wheel 40, transmission shaft 4 and the rotation of the 4th driving wheel 41, due to the 4th driving wheel 41 with
First driving wheel 20 is meshed, therefore power passes to the first driving wheel 20, since the first driving wheel 20 and power output shaft 2 are logical
The connection of freewheel clutch 23 is crossed, therefore power is ultimately transferred to power output shaft 2 and the wheel at 2 both ends of power output shaft is driven to turn
It is dynamic.When the speed of power output shaft 2 reaches certain value, counterweight part 2222 on pallet piece 222 by centrifugal force effect along remote
The direction movement of the off-axis heart makes to transport positioned at the pawl portion 2220 of opposite other end to axis direction under the action of lever principle
Dynamic, so that pawl portion 2220 be made to be meshed with the ratchet 221 on 21 outer circumference surface of driving member, when top gear, power is defeated by power
Enter the input of part 1, since power input 1 is fixedly connected with driving member 21, driving member 21 is rotated, due to 21 outer circle of driving member
Ratchet 221 on circumferential surface is meshed with the pawl portion 2220 on pallet piece 222, therefore drives pallet piece 222 and pallet piece frame 220
Rotation, since pallet piece frame 220 is fixedly connected with power output shaft 2, power is exported by power output shaft 1:1.
In conclusion the utility model is changed by the automatic centrifugation that setting is matched with driving member 21 and power output shaft 2
Retaining device 22, to make the speed change gear in the utility model that can realize that self shifter, shift are steady efficient.
The principles and effects of the utility model creation, and the reality that part uses only is illustrated in the above embodiments
Example is applied, is rather than limited the present invention；It should be pointed out that for those of ordinary skill in the art, not departing from this
Under the premise of utility model concept, various modifications and improvements can be made, these belong to the protection of the utility model
Range.
