Abstract
The utility model provides a kind of axis rear side motor of assisted electric bicycle, motor case is fixed on the rear side of bicycle body's axis, in casing, fixedly mount motor stator with casing, rotor is fixedly connected with rotating shaft, rotating shaft is by bearing and casing connection of rotating, rotating shaft one end is fixedly connected with motor sprocket, and sprocket wheel is connected with transmission mechanism of bicycle by chain; Bicycle middle shaft and machine shaft are in parallel position, and axis two ends connect pedal crankshaft, by the chain on manpower sprocket wheel, are connected with transmission mechanism of bicycle.Advantage is to improve the energy efficiency of power-assisted electric vehicle, and driven by power and manpower drive, and are independent of each other, and have solved the deficiency of conventional design.
Description
Technical field
The utility model patent relates to a kind of novel axis rear side motor.
Technical background
The central-shaft motor of common assisted electric bicycle, what motor power was transferred to that trailing wheel and manpower be transferred to that trailing wheel uses is same set of sprocket system.Wherein manpower input is the same with the mode of Regular Bicycle, with toe clip active toothed disk, rotates.Motor power is by a bidirectional clutch band active toothed disk.Because used bidirectional clutch, so when motor can drive bicycle walking, in the time of can avoiding assisted electric bicycle to travel, manpower input affects motor operation.
For traffic safety, there is the highest riding speed restriction countries in the world to bicycle.And the sprocket system of bicycle is acceleration system.The a set of sprocket system of the common use of motor and manpower, the rotating speed of motor just need to approach the rotating speed of manpower input in design.For electrical motor, this is very low rotating speed.In low speed situation, motor volume just need to be done greatly, but also can sacrifice electrical efficiency.
Current terms of settlement, be motor before being transferred to bidirectional clutch, first by deceleration system, slow down, to meet the demand that approaches manpower input speed.Cause like this complex structure, power of motor loss is large, mechanical wear is large problem.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of axis rear side motor of assisted electric bicycle, motor case is fixed on the rear side of bicycle body's axis, in casing, fixedly mount motor stator with casing, rotor is fixedly connected with rotating shaft, rotating shaft is by bearing and casing connection of rotating, and rotating shaft one end is fixedly connected with motor sprocket, and sprocket wheel is connected with transmission mechanism of bicycle by chain; Bicycle middle shaft and machine shaft are in parallel position, and axis two ends connect pedal crankshaft, by the chain on manpower sprocket wheel, are connected with transmission mechanism of bicycle.
Described motor sprocket and manpower sprocket wheel can be at the homonymy of bicycle rear or homonymies not.
Described manpower sprocket wheel is sprocket wheel or gear or belt pulley.
Described motor sprocket is sprocket wheel or gear or belt pulley.
The utility model has the advantage of the energy efficiency that improves power-assisted electric vehicle, driven by power and manpower drive, and are independent of each other, and have solved the deficiency of conventional design.The position of its placement, disguised better, and because be mounted in sidepiece in bicycle, so the weight distribution of whole assisted electric bicycle is more reasonable, ride safer.
Accompanying drawing explanation
Fig. 1 section-drawing of the present utility model;
Fig. 2 is the schematic diagram that the utility model is installed on position on bicycle;
Number in the figure explanation:
1-motor sprocket; 2-rotor; 3-stator; 4-casing; 5-machine shaft; 6-bicycle middle shaft; 7-motor; 8-car body.
Specific embodiment
Refer to shown in accompanying drawing 1,2, the utility model is a kind of axis rear side motor 7 of assisted electric bicycle, motor case 4 is fixed on the rear side of bicycle body's 8 axis 6, in casing 4, fixedly mount motor stators 3 with casing 4, rotor 2 is fixedly connected with rotating shaft 5, rotating shaft 5 is by bearing and casing 4 connection of rotatings, and rotating shaft 5 one end are fixedly connected with motor sprocket 1, and sprocket wheel 1 is connected with transmission mechanism of bicycle by chain; Bicycle middle shaft 6 is with motor 7 rotating shafts 5 in parallel position, and axis 6 two ends connect pedal crankshaft, by the chain on manpower sprocket wheel, are connected with transmission mechanism of bicycle.
Described motor sprocket 1 and manpower sprocket wheel can be at the homonymy of bicycle rear or homonymies not.
Described manpower sprocket wheel is sprocket wheel or gear or belt pulley.
Described motor sprocket 1 is sprocket wheel or gear or belt pulley.
Bicycle middle shaft 6 can parallel relative rotation with machine shaft 5.
When motor is not worked, manpower is ridden constant as ordinary bicycle type of drive, by bicycle middle shaft, drives manpower sprocket wheel, and sprocket wheel makes bicycle running by the chain transferring power on sprocket wheel.
During machine operation, rotor drives rotating shaft 5 to rotate, thereby 1 rotation of drive motor sprocket wheel is rotated in rotating shaft 5, by the chain transferring power on motor sprocket 1, makes bicycle running.Motor drives and manpower drives non-interference.
