7 rotations of rear rotor axle are rotated in motor 6 energisings, and the rotor shaft gear 14 that is located at rotor shaft 7 ends rotates and 16 rotations of driving engagement driven gear thereupon.
Under the initial condition, the ratchet 37 that sliding part 11 is in 15 two sections of driven shafts sticks up into end, and each ratchet 37 is stuck up into end jack-up, and the internal tooth 42 of ratchet 37 other end perk ends and cooresponding driven gear 16 breaks away from, two driven gears 16 can be neutral gear around driven shaft 15 idle running at this moment.
The position of adjustment slide 11, make sliding part 11 leave the locational ratchet 37 of driven shaft 15 the preceding paragraphs, ratchet 37 on this fragment position under the effect of torsion spring 36 its stick up end stick up in the driven axis hole 13 into, its perk end snaps in the internal tooth 42 of cooresponding driven gear 16, these driven gear 16 band driven shafts 15 rotate, and when driven shaft 15 rotates, drive end face 2 and rotate, hub circle 1 is rotated around fulcrum 4, and be one grade this moment.
When sliding part 11 leaves on the driven shaft 15 ratchet 37 on another fragment position, as mentioned above, driven gear 16 on this fragment position drives driven shaft 15 and rotates, because ratchet 37 has unidirectional drive with the ratchet snap-in structure structure that driven gear 16 forms, and 16 diameters of the driven gear on this fragment position are less, rotating speed is also fast than another driven gear 16, and driven shaft 15 was just driven by the driven gear on this fragment position 16 and rotated this moment, and be second gear this moment.
Hence one can see that, controls interlock between driven gear 16 and the driven shaft 15 by adjustment slide 11, can realize that the two-stage speed change regulates.The rest may be inferred, a plurality of rotor shaft gears 14 and driven gear 16 is set just can realizes the multi-change speed adjusting.
Be fixed with driver blade 19 on the described driven shaft 15, described driver blade 19 is provided with groove 31, and described end face 2 inboards are provided with the projection 21 that can insert in groove 31, are provided with damping spring 20 between described groove 31 and projection 21.When driven shaft 15 runnings, pass through foregoing description, can learn that driven shaft 15 will drive driver blade 19 rotations, driver blade 19 can be oppressed damping spring 20 by elder generation's driver blade 19 when end face 2 rotates a certain angle, by damping spring 20 drive blockss 21 end face 2 and hub circle 1 are rotated together afterwards, realize the purpose of damping.
As shown in Fig. 7, Fig. 8, Fig. 9, Figure 11, be outside they are different with embodiment 1: have two motors 6 to be fixed on the external diameter of fulcrum 4, the rotor shaft 7 of these two motors is parallel with fulcrum 4.The shell of described two motors 6 is a conjoined structure, after as long as shell is fixed on the fulcrum 4, corresponding motor just has been fixed, therefore, the installation of motor 6 is only relevant with fulcrum 4, and is irrelevant with hub circle 1, do not need to consider the concentricity problem of rotor shaft and fulcrum 4, be convenient to select as required identical or different types of motor, comprise the rotating speed difference, size difference or power are not equal.And relative fixed between motor and the motor, the integral rigidity structure is good.Rotor shaft gear 14 diameters on described two rotor shafts 7 are identical or inequality, and this embodiment has two gear clusters, and the rotor shaft gear 14 of two motors also can be distinguished individual drive driven gear 16.Because driven shaft 15 and driven gear 16 are arranged on the fulcrum 4 and can rotate around it, and are in the center of hub circle 1, motor 6 can be provided with around fulcrum 4 external diameter annular spread.Therefore under hub circle 1 thickness unmodified condition, a plurality of motors 6 can be set in hub circle 1.When the rotating speed of two motors 6 is identical with power, corresponding two rotor shaft gear clusters are identical, and both transmitting ratio was identical, and the gear cluster of the rotor shaft 7 on two motors 6 meshes when driving driven gear 16 simultaneously, and power ratio embodiment 1 is twice.The transmitting ratio of the driven gear 16 that is meshed with it when two rotor shaft 7 gear clusters is inequality, and when perhaps corresponding gear cluster was inequality, two motors 6 are independent drive hub circles 1 respectively, also can realize the operation of multiple shift.
As shown in Fig. 12, its with embodiment 1,2 different outside be: have three motors 6 to be fixed on the external diameter of fulcrum 4, the rotor shaft 7 of these three motors is parallel with fulcrum 4.The shell of described three motors 6 is a conjoined structure, and this embodiment has three gear clusters, and the gear cluster while driving engagement driven gear 16 of the rotor shaft 7 of three group rotor axles 7 and 14, three motors 6 of rotor shaft gear is promptly arranged.Because the space between fulcrum 4 and the hub circle 1 is an annular, these three motors 6 can be arranged in this annular space, the electric wheel hub of this structure can effectively utilize the space in the hub circle 1, and it is under hub circle 1 thickness unmodified condition, and horsepower output can increase by two times than embodiment 1.In addition, the transmitting ratio of the driven gear 16 that is meshed with it as the rotor shaft gear 14 of three motors 6 is set to when inequality, and three motors 6 can be distinguished independent drive hub circle 1, also can realize the operation of multiple shift.
Each gear described in the utility model also can be belt pulley or sprocket wheel, and engaged transmission each other becomes belt or chain gear, also can reach the technique effect of driving coupling.
