It is fixedly connected inside axle 3, torsion passes to left axle 3, left axle 3 continues this pedal force passes to the screw mandrel 1 of connection fixed thereto,
Screw mandrel 1 rotates, and drives clutch block 2 contact motor output 5.In above process, because left axle 3 is subject to torsion, it is arranged on its table
The torsion torque sensor in face is signaled to motor, electric motor starting, and output driving power passes through reducing gear, single direction ratchet 8 to motor
Output section 5.Therefore, manpower and electric power collective effect, on clutch block 2, drive electric motor car to travel, manpower drives together with electric power
Electric motor car moves ahead.
In addition, as left foot tramples forward crank, pedal force directly passes to the screw mandrel 1 of connection fixed thereto by left axle 3,
Subsequent process is ibid.
Need in a flash, right crus of diaphragm tramples crank backward, and right axle 4 rotates backward, and pedal force is input to right axle 4 other end, because
This end is fixedly connected with inside left axle 3, and torsion passes to left axle 3, and left axle 3 continues for this pedal force to pass to connection fixed thereto
Screw mandrel 1, screw mandrel 1 rotates, and drives clutch block 2 to separate motor output 5.In above process, because left axle 3 is reversely turned round
Power, the torsion torque sensor being arranged on its surface is signaled to motor, and motor stops output, and motor and reducing gear is used
Property motion by clutch block separate, no longer act on chain, stop and smoothly complete.
In addition, as left foot tramples crank backward, pedal force directly passes to the screw mandrel 1 of connection fixed thereto by left axle 3,
Subsequent process is ibid.
In above-mentioned control process, except detecting in addition to pedal force by torsion torque sensor, equally can utilize velocity pick-up
Detecting, pedal force makes central axis to device, by this velocity of rotation signal come the output of controlled motor or stopping.
Second embodiment
This enforcement arranges and is illustrated with putting electric bicycle in concentric co-axial, as described in Fig. 2 and Fig. 3, puts electronic in one kind
