The utility model is not when substantially changing the basic structure of bicycle, volume, weight, using function, physical demands, increase electric boosted, Three models is provided: total man's force mode, all-electric force mode, people's electricity mixed power pattern are for selectable middle dual-power driving device.
Utility model works principle:
These practical three kinds of using forestland are respectively: total man's force mode; All-electric force mode; People's electricity mixed power pattern.
When cyclist is by the all-electric force mode of model selection, by controlling the maximum output power of brshless DC motor and rotating speed, realize the max. output torque of middle dual-power driving device and the adjustment of rotating speed.Power is rotated output from core motor axle 3 by motor, make difference tooth while that the eccentric part 301 of core motor axle 3 driving duplex stepped planet gears 904 to rotate to move with internally toothed annulus 902, duplex stepped planet gears 904 with eccentric part 301 revolve round the sun while under the meshing resistance effect of internally toothed annulus 902 around the center rotation of eccentric part 301, the secondary low level gear 942 of duplex stepped planet gears 904 is just made to differ from tooth and is moved to drive and export internally toothed annulus 10 and rotate with output internally toothed annulus, high owing to exporting internally toothed annulus 10 revolution ratio output hollow shaft 6, second overriding clutch engages, power exports from output hollow shaft 6.Now, because stretcher axle 2 does not turn, output hollow shaft 6 revolution ratio stretcher axle 2 is high, and first is more than power-transfer clutch 7 is separated, and stretcher axle 2 keeps not turning state.
When cyclist selects people's electricity mixed power, now, can trample stretcher and drive stretcher axle 2 to rotate, when stretcher axle 2 revolution ratio output hollow shaft 6 is high, first is more than power-transfer clutch 7 engages, and footboard drives output hollow shaft rotates.Meanwhile, tachogen detects pedal spindle 2 rotating signal, starter motor.Power is rotated output from core motor axle 3 by motor, make difference tooth while that the eccentric part 301 of core motor axle 3 driving duplex stepped planet gears 904 to rotate to move with internally toothed annulus 902, duplex stepped planet gears 904 with eccentric part 301 revolve round the sun while under the meshing resistance effect of internally toothed annulus 902 around the center rotation of eccentric part 301, the secondary low level gear 942 of duplex stepped planet gears 904 is just made to differ from tooth and is moved to drive and export internally toothed annulus 10 and rotate with output internally toothed annulus, high owing to exporting internally toothed annulus 10 revolution ratio output hollow shaft 6, second overriding clutch engages, power exports from output hollow shaft 6, realize pedal force and motor power drives hollow shaft 6. jointly
When pedal spindle 2 stops the rotation or reverses, tachogen no signal exports, motor stalls.
When cyclist selects total man's power to drive, core motor axle 3 not rotation, exports internally toothed annulus 10 and does not also just rotate, and low owing to exporting internally toothed annulus 10 revolution ratio output hollow shaft 6, the second overriding clutch 8 is separated, and output hollow shaft 6 keeps not turning.Now, can trample stretcher and drive stretcher axle 2 to rotate, stretcher axle 2 revolution ratio output hollow shaft 6 is high, and first is more than power-transfer clutch 7 engages, and the independent driver output hollow shaft of stretcher axle rotates.
