Embodiment Construction

[0025] see figure 1 , a bicycle 10 is shown in the figure, wherein a DC motor F can be mounted on the hub spindle 12a of the front wheel 12, or can also be mounted on the hub spindle 14a of the rear wheel 14, thus forming a mechanical drive system. The crank mechanism 20 of the mechanical drive unit A.

[0026] figure 1 The DC motor F is mounted on the hub spindle 14a of the rear wheel 14 in the shown example.

[0027] A crank 20b having a crank pedal 20c is provided on a crank spindle 20a, and a chain 20d engaged on a sprocket 20e is also engaged on a sprocket 30d of the hub spindle 14a of the rear wheel 14, so that the crank pedal 20c The rotation of the crankshaft 20a and chain 20d is transferred to the hub spindle 14a of the rear wheel 14 to form a ratchet 15.

[0028] exist Figure 5 , 6, a metal outer rotor 30 of the direct drive brushless DC motor F of the bicycle 10 is rotatably set on a hub spindle 14a which becomes the main spindle.

[0029] More specifically, b...

Abstract

The invention provides a bicycle which is matched with a DC motor, a directly driving three-phase DC motor and a driving device thereof. The bicycle comprises a directly driving no-brush external rotor three-phase DC motor which is arranged on the hub mandrel of the front wheel or the rear wheel, a brake device which is arranged on a brake cover and operated by a sensor, a plurality of probing pawls which are arranged at the side surface of the motor at intervals, a probing device which is arranged on a rear fork and probes the starting and rotation of at least two pawls, and a device which drives the motor according to the rotation of the pawls and the starting signals; the motor can be easily stopped and can obtain the high output moment with low frequency, high efficiency and low loads.

Description

technical field [0001] The present invention relates to a bicycle equipped with a direct current motor, a direct drive brushless three-phase direct current motor and its driving device, more particularly to a bicycle equipped with a direct current motor, a direct drive brushless three-phase direct current The brush three-phase DC motor and its driving device have a thin structure, safe operation, no gears, good braking force and can rotate at low frequency and low speed to obtain high output torque and high efficiency. [0002] Correspondingly, the energy consumption of the direct drive brushless three-phase DC motor of the present invention is very small, the noise is also low, and the adjustment of the mechanical angle is also very easy, so once the storage battery of the DC motor is charged, the bicycle can travel for a long time. Distance (up to 45 kilometers on a smooth road). [0003] For this purpose, an ordinary bicycle can be easily converted into a DC motor-driven b...
