Abstract
The utility model discloses a bicycle motor and an assorted transmission structure thereof. The assorted transmission structure comprises a motor arranged on a wheel of a bicycle. The axis of the motor is internally provided with an internal-thread annular groove which is internally provided with and in threaded coordination with a circular ring; a monodirectional ratchet step is arranged on the inner ring of the circular ring; a flywheel is coaxially integrated with an elastic pawl wheel which is accommodated inside the annular groove of the circular ring; an elastic pawl is directionally matched with the monodirectional ratchet step; and the flywheel is positioned besides the circular ring. When the motor is at work, the elastic pawl slides on the monodirectional ratchet step under the restriction of the monodirectional ratchet step; and when a person rides the bicycle, the elastic pawl extends out to match with the monodirectional ratchet step and the flywheel is stressed to drive the wheel to move. By integrating the elastic pawl wheel with the flywheel, the utility model fully reduces the diameter of the flywheel, increases the transmission ratio and ensures the normal running of the bicycle under the action of labor power.
Description
Technical field
The utility model relates to the bicycle part field, relate in particular to the motor of Electrical 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.
The utility model content
The purpose of this utility model provides a kind of bicycle motor and supporting drive mechanism thereof.
The technical solution of the utility model 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 negative thread circular groove, ccontaining and screw thread fit has an inner ring that the annulus on unidirectional sour jujube rank is set in the negative thread circular groove, flywheel and coaxial being connected as a single entity of elastic pawl wheel, the elastic pawl wheel is contained in the circular groove 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 utility model adopts being provided with that elastic pawl wheel and flywheel be connected as a single entity, fully reduced the diameter of flywheel, strengthened transmitting ratio, but guaranteed bicycle cruising under the manpower effect.
Description of drawings
Fig. 1 is the unitized construction scheme drawing of a kind of embodiment of the utility model.
Fig. 2 is the installation effect scheme drawing of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing 1 and accompanying drawing 2 embodiment of the present utility model is 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 negative thread circular groove 21, ccontaining and screw thread fit has an inner ring that the annulus 3 on unidirectional sour jujube rank 31 is set in the negative thread circular groove 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 circular groove 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 utility model uses, earlier wheel 1 is fixed on the bicycle rear axle, rear axle is fixed with nut after passing wheel 1 axle center, negative thread circular groove, elastic pawl wheel, flywheel successively.
Above shown detailed embodiment of the present utility model, apparent, those skilled in the art can carry out the part modifications and changes under prerequisite of the present utility model; The content of mentioning in description above and the accompanying drawing is the illustration of property as an illustration only, is not to be to restriction of the present utility model; Have the structure of the folding bicycle back vent of technical characterictic described herein, all fall into this patent protection domain.
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 negative thread circular groove, ccontaining and screw thread fit has an inner ring that the annulus on unidirectional sour jujube rank is set in the negative thread circular groove, flywheel and coaxial being connected as a single entity of elastic pawl wheel, the elastic pawl wheel is contained in the circular groove of annulus, and elastic pawl selects to cooperating with unidirectional sour jujube rank, and flywheel is positioned at the annulus side.
