Embodiment 1
As it is shown in figure 1, described double pawl nozzle variable speed electric motors, particularlies, including motor 3, motor 3 connects gearbox body 21, speed change
Casing 21 is provided with hollow output shaft 5, equipped with ratchet 13 in the ratchet loose slot 12 in hollow output shaft 5, and ratchet 13
It is provided with two pawl nozzles 131.
It is fixed with gearbox body 21 on described motor 3, in described casing 21, is provided with hollow output shaft 5 and power shaft
6, fulcrum 20 is through axis hole 15, and described hollow output shaft 5 is set on fulcrum 20 coaxially.Described power shaft 6
With motor shaft 46 driving coupling, one end of power shaft 6 is provided with input shaft gear 45, input shaft gear 45 and motor shaft tooth
Wheel 47 engagement, single power shaft 6 and the driving gear 10 being fixed on this power shaft 6 form a gear train.Described
Hollow output shaft 5 is connected with wheel hub 1, and described hollow output shaft 5 is set on fulcrum 20.
Described hollow output shaft 5 is provided with at least two driven gear 9, and driven gear 9 can turn in hollow output shaft 5
Dynamic, each driven gear 9 diameter is different, and on same power shaft 6, correspondence is fixed with and each described driven gear 9
The driving gear 10 of engagement.The present invention is provided with two driven gears 9 in hollow output shaft 5, and two driven gears 9 pass through
Jump ring 56 is fixed in hollow output shaft 5, and the diameter of each driven gear 9 in hollow output shaft 5 differs.
Described driven gear 9 is provided with internal tooth 11, is arranged with in this section of hollow output shaft 5 that driven gear 9 is sheathed
A pair ratchet loose slot 12, is provided with ratchet 13 in ratchet loose slot 12, ratchet 13 can be along hollow in ratchet loose slot 12
Output shaft 5 radially tilting, for making ratchet 13 be easily installed, described hollow output shaft 5 is provided with ratchet axis hole 57,
Being provided with pawl axis 55 in ratchet axis hole 57, ratchet 13 can be around the limited rotation of pawl axis 55.Ratchet 13 is provided with work
Being used in hollow output shaft 5 spring 14 making its one end tilt, spring 14 one end is pressed on ratchet 13, and the other end is pressed in
In hollow output shaft 5.In the case of normality, spring 14 makes ratchet 13 tilt the end outside in hollow output shaft 5, separately
End is in axis hole 15.When ratchet loose slot 12 is stuck up in ratchet 13 outer end, two pawl nozzles 131 on ratchet 13 can
It is stuck in two internal tooths 11 simultaneously and is connected together transmission with internal tooth 11, making driven gear 9 and hollow output shaft 5 combine one
Rise and rotate.When ratchet 13 outer end is stuck up into ratchet loose slot 12, pawl nozzle 131 separates with internal tooth 11, then driven gear 9
It is to rotate around hollow output shaft 5.So ratchet 13 and driven gear 9 forms a ratchet snap-in structure, has unidirectional driving
Dynamic property.Sliding part 16 it is provided with, when sliding part 16 slides axially in axis hole 15 in the axis hole of described hollow output shaft 5
Can stick up into end by jack-up ratchet 13.
Described sliding part 16 is provided with pilot hole 63, described pilot hole 63 axially and axis hole 15 axially in parallel,
Fulcrum 20 is arranged in described pilot hole 63, and such sliding part 16 can slide axially on fulcrum 20.Described slip
Part 16 is connected with adjusting rod 4.
After motor 3 energising rotates, input shaft gear 45 when generator shaft gear 47 rotates, is driven to rotate, thus band driven input shaft
6 rotate.Two driving gears 10 of power shaft 6 rotate with, and the driven gear 9 engaged with driving gear 10 is the most therewith
Rotate.
Under original state, the ratchet 13 of the driven gear 9 that sliding part 16 is in hollow output shaft 5 top gear sticks up into end position,
Being stuck up by ratchet 13 into end jack-up, ratchet 13 other end tilts the pawl nozzle 131 of end and the internal tooth 11 of corresponding driven gear 9
Departing from, the driven gear 9 of top gear is i.e. dallying around hollow output shaft 5, because internal tooth and its of low or first gear driven gear 9 are right
The pawl nozzle 131 on ratchet 13 answered is connected together, and now hollow output shaft 5 is just driven rotation by the driven gear 9 of low or first gear
Turning, hollow output shaft 5 drives wheel hub 1 to rotate around fulcrum 20 thus completes the power output of one grade, and the speed of vehicle is also
Otherwise the slowest moment of torsion is maximum.
It follows that control driven gear 9 and hollow output shaft 5 in the position of axis hole 15 by adjustment slide 16
Between linkage, it can realize two-stage gearshift adjustment.The rest may be inferred, just arranges multiple driving gear 10 and driven gear 9
Multi-change speed regulation can be realized.
The shell of motor 3 is fixed with electric magnet 39, and the moving pin 28 of electric magnet 39 is connected with adjusting rod 4.
Electric magnet 39 pulls moving pin 28, adjusting rod 4 and sliding part 16 when being energized, now sliding part 16 leaves and high speed
The ratchet 13 that the driven gear 9 of shelves coordinates stick up into end, the pawl nozzle 131 tilting end of ratchet 13 just driven with top gear
The internal tooth 11 of gear 9 is connected together, and it is two grades that the driven gear 9 of top gear drives hollow output shaft 20 to rotate now.
The electric magnet of the double pawl nozzle variable speed electric motors, particularly of the present invention is the electric magnet 39 of way moving and two-way holding, when electric magnet 39 is another
During the energising of one end, electric magnet 39 produces magnetic force and is drawn through by moving pin 28, promotes adjusting rod 4 He when moving pin 28 moves
Sliding part 16 moves toward wheel hub 1 direction, the ratchet 13 that sliding part 16 will coordinate with driven gear 9 internal tooth 11 of top gear
Stick up into end jack-up, the pawl nozzle 131 tilting end of ratchet 13 just departs from internal tooth 11, and the driven gear 9 of top gear is only around sky
Heart output shaft 5 dallies, and the driven gear 9 of top gear just loses to hollow output shaft 5 transmission capacity, the most just by low or first gear
Driven gear 9 drive hollow output shaft 5 to rotate, hollow output shaft 5 connects wheel hub 1 and rotates around fulcrum 20, thus complete
The power becoming one grade exports.
As shown in Figure 7 to 9, described power shaft 6 being fixed with input tooth 45, driving gear 10 then empty set is at main shaft
On 6, driving gear 10 can rotate in a limited degree on power shaft 6.
After motor 3 energising rotates, driving input tooth 45 to rotate when generator shaft gear 47 rotates, input tooth 45 can be first to master
Moving gear 10 rotates a certain angle, and makes groove 36 elastic element 38 be compressed, and is driven by flexible member 38 afterwards
Projection 37 makes driving gear 10 rotate together, and power passes to output shaft 5 and wheel hub 1 after above-mentioned damping, buffering again.
Thus realize the purpose of damping, buffering.
Flexible member of the present invention is that spring can also replace with rubber, can reach the technique effect of damping, buffering equally.
