Abstract
The invention discloses a bicycle motor and a matched transmission structure thereof. The bicycle motor comprises a motor arranged on a wheel of a bicycle; the inner side of an axis of the motor is provided with an internal thread circular groove; a circular ring of which an inner ring is provided with a unidirectional pawl step is accommodated in and is in thread match with the internal thread circular groove; a flywheel and an elastic pawl wheel are coaxially connected into a whole; the elastic pawl wheel is accommodated in the circular groove of the circular ring; an elastic pawl and the unidirectional pawl step are matched in a selectable direction; and the flywheel is positioned on the side of the circular ring. When the motor works, the elastic pawl is restrained by the unidirectional pawl step to slide on the unidirectional pawl step; and when the bicycle is ridden by a man, the elastic pawl extends to be matched with the unidirectional pawl step, and the flywheel is stressed to drive the wheel to move ahead. In the invention, after the elastic pawl wheel and the flywheel are connected into a whole, the diameter of the flywheel is fully reduced, the transmission ratio is increased, and the bicycle can normally drive under the action of manpower.
Description
Technical field
The present invention relates to the bicycle part field, relate in particular to the motor of electric bicycle and the mechanical transmission structure supporting with it,
Background technology
Disclosed a kind of electric assisted bicycle on the market, its rear axle is provided with motor and flywheel, after motor is installed in the rear rim, motor is arranged with the coaxial branch of flywheel, after the motor stall, can ride the axis chain wheel and drive flywheel by the engagement of chain and flywheel and advance, this set is because motor and the common occupation space of flywheel are bigger, the freewheel number of teeth is more, thus influence the riding speed of bicycle, and be not easy to be folded with.Thereby be necessary to be improved on this basis.
Summary of the invention
The purpose of this invention is to provide a kind of bicycle motor and supporting drive mechanism thereof.
Technical scheme of the present invention is achieved in that
A kind of bicycle motor and supporting drive mechanism thereof are provided, comprise the motor that is installed on the cycle wheel, it is characterized in that: described electrical axis inboard is provided with the internal thread cannelure, ccontaining and threaded engagement has an inner ring that the annulus on unidirectional sour jujube rank is set in the internal thread cannelure, flywheel and coaxial being connected as a single entity of elastic pawl wheel, the elastic pawl wheel is contained in the cannelure of annulus, and elastic pawl selects to cooperating with unidirectional sour jujube rank, and flywheel then is positioned at the annulus side; During machine operation, elastic pawl is subjected to the constraint on unidirectional sour jujube rank and slides on unidirectional sour jujube rank, and when manpower was ridden, elastic pawl stretched out with unidirectional sour jujube rank and cooperates, and flywheel forced belt motor-car wheel moves ahead.
After the present invention adopts being provided with that elastic pawl wheel and flywheel be connected as a single entity, fully reduced the diameter of flywheel, strengthened gearratio, but guaranteed bicycle cruising under the manpower effect.
Description of drawings
Fig. 1 is the combining structure schematic diagram of an embodiment of the present invention.
Fig. 2 is the installation effect schematic diagram of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing 1 and accompanying drawing 2 embodiments of the invention are described:
A kind of bicycle motor and supporting drive mechanism thereof are provided, comprise the motor 2 that is installed on the cycle wheel 1, inboard, described motor 2 axle center is provided with internal thread cannelure 21, ccontaining and threaded engagement has an inner ring that the annulus 3 on unidirectional sour jujube rank 31 is set in the internal thread cannelure 21, flywheel 4 is taken turns 41 coaxial being connected as a single entity with an elastic pawl, elastic pawl wheel 41 is contained in the cannelure 21 of annulus 3, and elastic pawl 411 selects to cooperating with unidirectional sour jujube rank 31, and 4 on flywheel is positioned at annulus 3 sides; During motor 2 work, elastic pawl 411 is subjected to the constraint on unidirectional sour jujube rank 31 and slides on unidirectional sour jujube rank 31, and when manpower was ridden, elastic pawl 411 stretched out with unidirectional sour jujube rank 31 and cooperates, and flywheel 4 forced belt motor-cars wheel 1 moves ahead.
The detent mechanism of described elastic pawl wheel is the detent mechanism of flywheel commonly used on the market, and when flywheel was stressed, ratchet elasticity was stretched out, and the ratchet pressurized slides when stressing.
When the present invention uses, earlier wheel 1 is fixed on the bicycle rear axle, rear axle is fixed with nut after passing wheel 1 axle center, internal thread cannelure, elastic pawl wheel, flywheel successively.
Above shown detailed embodiment of the present invention, apparent, those skilled in the art can carry out the part modifications and changes under prerequisite of the present invention; The content of mentioning in description above and the accompanying drawing is the illustration of property as an illustration only, is not to be limitation of the present invention; Have the structure of the folding bicycle back vent of technical characterictic described herein, all fall into this patent protection range.
Claims (1)
1. a bicycle motor and supporting drive mechanism thereof, comprise the motor that is installed on the cycle wheel, it is characterized in that: described electrical axis inboard is provided with the internal thread cannelure, ccontaining and threaded engagement has an inner ring that the annulus on unidirectional sour jujube rank is set in the internal thread cannelure, flywheel and coaxial being connected as a single entity of elastic pawl wheel, the elastic pawl wheel is contained in the cannelure of annulus, and elastic pawl selects to cooperating with unidirectional sour jujube rank, and flywheel is positioned at the annulus side.
