The working process of two kinds of mode of operations of the utility model is as follows:
1. select " level road " (or title " power saving ") mode of operation:
(1) foot-operated separately the driving: the rider steps stretcher, pedal spindle 6 beginnings rotation forward, and right bevel type differential gear 16 is rotated synchronously by flat key 17, ratchet 21 on the right bevel type differential gear 16 drives pinion carrier 12 and rotates synchronously, pinion carrier 12 drives output sleeve 19 by torque spring 18, the sprocket wheel 22 that is fixedly connected on the output sleeve 19 just drives vehicle to overtake by chain, thereby realize foot-operated the driving, left side bevel type differential gear 4 is under the drive of bevel planet gear 10, also follow rotation forward, but because the unidirectional gearing of ratchet 9 is arranged between left bevel type differential gear 4 and the worm gear seat 2, therefore can not drive worm gear seat 2 and worm gear 1 rotation, and this moment, motor did not start as yet.
(2) realize motor-driven by foot-operated the driving: when the revolution of rider pedals stretcher reaches the revolution of setting, Hall element 8 is input to control circuit with signal, power by control circuit, start assist motor, and according to the raising of pedal spindle 6 rotating speeds, control circuit changes the size to the assist motor power supply.Can be after the of short duration time-delay of setting after pedal spindle 6 stops operating, control circuit is stopped power supply, and motor stops operating automatically.
And under the situation that motor remains in operation, power when the rider pedals stretcher, during greater than the predetermincd tension of torque spring 18 (for example go up a slope or quicken), can produce the displacement of certain angle between second disk 13 and the 3rd disk 14, Hall element 15 is sensed the variation of magnetic force, the signal that offers control circuit is changed, begin to improve power supply by control circuit decision, thereby change the power-assisted degree of motor assist motor; Rotating speed of motor increases, driving worm gear seat 2 by the worm and gear assembly rotates, worm gear seat 2 drives left bevel type differential gear 4 by ratchet 9 and rotates forward, this moment, bevel planet gear 10 was subjected to the drive of right bevel type differential gear 16 and left bevel type differential gear 4 simultaneously, drive pinion carrier 12 rotations with left and right bevel type differential gear 4,16 synthetic power and rotating speeds, pinion carrier 12 drives 19 rotations of output sleeve by torque spring 18, makes sprocket wheel 22 drive the chain drive vehicle to overtake.
2. select " upward slope " (or title " reinforcing ") mode of operation:
Under this pattern, software program on the control circuit is arranged to: when motor after pedal spindle 6 reaches the revolution of setting and has started motor, motor obtains bigger electric power continuous running, the cyclist can stop to step stretcher, the running of motor can not quit work because of the cyclist stops to step pedal spindle 6, and meanwhile, electromagnet 29 is under the power supply of control circuit, promote ratchet 27 and press to and block ratchet 5, pedal spindle 6 can not rotated backward because of the application force of bevel planet gear 10; Motor rotates, by the transmission of worm and gear assembly, 2 rotations of worm gear drives worm gear seat, driving left side difference finishing bevel gear cuter 4 by ratchet 9 rotates forward, because right bevel type differential gear 16 stops operating, principle according to epicyclic gear transmission, bevel planet gear 10 just drives pinion carrier 12 with 1/2 of left bevel type differential gear 4 rotating speeds and rotates forward, drive output sleeve 19 by pinion carrier 12 by torque spring 18, and, output torque is doubled, under this pattern to sprocket wheel 22 outputting powers, when returning " level road " (or title " power saving ") pattern when the cyclist operates Brake lever or with the select switch setting, " upward slope " (or title " reinforcing ") mode of operation stops.
The utility model can be widely used in various Moped Scooters such as the car, scooter of bicycle, three-wheel vehicle, four wheel drive.
Embodiment of the present utility model is not limited thereto; according to foregoing of the present utility model; ordinary skill knowledge and customary means according to this area; do not breaking away under the above-mentioned basic fundamental thought of the utility model prerequisite; the utility model can also be made modification, replacement or the change of other various ways, all drops within the utility model rights protection scope.
