Abstract
The utility model relates to a kind of bicycle electric boosting device.With reference to specification digest accompanying drawing, this device comprises the built-in retarder of motor 1(, power-transfer clutch, sensor selectable unit (SU)), the parts such as battery, electric machine controller, its motor is arranged on bicycle five-pipe side, motor output power (by electric machine built-in selectable unit (SU) retarder and power-transfer clutch) is transferred to bicycle middle shaft, by the chain wheel of middle axle driven to bicycle five-pipe opposite side, bicycle freewheel is transferred to, by flywheel to bicycle rear by chain wheel.The advantage of this device is: ordinary bicycle all can use, install simple, replace the original parts of bicycle without the need to changing, motor does not bear vehicle and personage's weight, friction drag is little, driving efficiency is high, and appearance looks elegant coordinate, simple and compact for structure, productive costs is low.
Description
Technical field
The utility model relates to a kind of bicycle electric boosting device.
Background technology
At present, the electric booster for ordinary bicycle mainly contains two types: flower-drum wheel hub integrated motor formula work-saving device and built-in motor formula work-saving device.Wherein the motor of flower-drum wheel hub integrated motor formula work-saving device need bear car load major part weight, thus thus waste of power is large greatly for motor friction drag, when weight, motor easily damages, such device can not change motor-driven ratio, and under climbing waits low-speed big situation windward, electrical efficiency is very low.Built-in motor formula work-saving device does not bear vehicle and personage's weight, and not fragile, frictional loss is little, and change motor-driven ratio by mechanical transmission, motor working efficiency is high.But common built-in motor or the special vehicle frame of need coordinate with it or the not compact overall appearance that affects of complex structure is coordinated and installs loaded down with trivial details.
Summary of the invention
With reference to accompanying drawing 1, this device comprises the built-in retarder of motor 1(, power-transfer clutch, sensor selectable unit (SU)), the parts such as battery, electric machine controller, its motor is arranged on bicycle five-pipe side, motor output power (by electric machine built-in selectable unit (SU) retarder and power-transfer clutch) is transferred to bicycle middle shaft, by the chain wheel of middle axle driven to bicycle five-pipe opposite side, bicycle freewheel is transferred to, by flywheel to bicycle rear by chain wheel.
The advantage of this device is: ordinary bicycle all can use, install simple, replace the original parts of bicycle without the need to changing, motor does not bear vehicle and personage's weight, friction drag is little, driving efficiency is high, and appearance looks elegant coordinate, simple and compact for structure, productive costs is low.
