Abstract
The invention relates to an electric assister for bicycles. Referring to the abstract drawing of the description, the electric assister comprises parts such as a motor (1) (in which optional parts, such as a speed reducer, a clutch and a sensor, are arranged), a battery and a motor controller, the motor is mounted on one side of a bottom bracket of a bicycle, and the motor outputs power (via the optional parts arranged in the motor, i.e. the speed reducer and the clutch) which is transmitted to the bottom bracket of the bicycle, then a crankset of the other side, a freewheel of the bicycle via the crankset and then a rear wheel of the bicycle. The electric assister has the following advantages that the electric assister can be used on ordinary bicycles, and is easy to mount, the original parts of the bicycle do not need to be changed or replaced, the motor does not bear bicycle and human weights, the frictional resistance is low, the transmission efficiency is high, moreover, the appearance is attractive and coordinate, the structure is simple and compact, and the production cost is low.
Description
Technical field
The present invention 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 the chain wheel that bicycle middle shaft is transferred to opposite side again, is transferred to bicycle freewheel is transferred to bicycle rear again 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.
Claims (2)
1. for an electric booster for bicycle, it is characterized in that: comprise the parts such as motor (built-in retarder, power-transfer clutch, sensor selectable unit (SU)), battery, electric machine controller.
2. according to claim 1 for the electric booster of bicycle, it is characterized in that: described 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 the chain wheel that bicycle middle shaft is transferred to opposite side again, is transferred to bicycle freewheel is transferred to bicycle rear again by chain wheel.
