Description
Affiliated technical field
The present invention relates to the electronic hub wheel technology of a kind of brand new.
Background technology
As everyone knows, the micro-miniaturisation of Electrical Bicycle has an obstacle that is difficult to overcome-big motor to hang the electric wheel hub of big flywheel.The wheel footpath (comprising Electrical Bicycle, electro-tricycle, electronic tricycle for the disabled etc. here) of battery-driven car, present optimum dimension both domestic and external is more than 22.5in, because foot-operated help that to ride the minimum flywheel that battery-driven car articulates be 16 teeth, with 48 tooth big trochal discs, 22.5in the speed index that battery-driven car is ridden is 67.5, this can not show a candle to 78 of 26in bicycle, if the wheel footpath is little of 16in, the speed index has only 48, and riding is exactly a perambulator.Say nothing of popular direct current brushless permanent magnet motor and contain cored and thick big coil, and heavy.Therefore, use prior art will be provided with the foot-operated battery-driven car micro-miniaturisation of riding function that helps.Chinese invention patent wheel hub motor (ZL2005101125005) is though provided a solution, but technological improvement is very little, its reason one is that sprocket wheel is reduced to 14 teeth from 16 teeth, its reason two is that old-fashioned electric machine structure is not done any improvement, and its result can only make the speed of the Electrical Bicycle of the big heaviness of body slightly promote.
Summary of the invention
Purpose of the present invention is exactly the electronic hub wheel that a kind of brand new technical will be provided, this electronic hub wheel has Ultra-thin electric machine and the whole technology that flies that connects, volume is little, in light weight, transmitting ratio is big, thereby wheel footpath can be accomplished extra smallly, and tire outside diameter is the disc type electric machine electrodynamic hub wheel with continuous flying head of 16in, power 1KW only, its foot-operated riding speed index is 85.3, has surpassed the 28in bicycle!
For realizing the technical goal of foregoing invention, the technical solution used in the present invention is: electrodynamic hub wheel with continuous flying head is by main shaft and be fixed on motor coreless disc type motor particularly on the main shaft, reductor, power-transfer clutch, the outer rotor (wheel hub shell) and several most of formations of disjunctor flywheel that have Lian Feitou, wherein the stator casing of disc type electric machine is fixed on the main shaft and can not rotates, on stator, be provided with stator coil, the output shaft of disc type electric machine is installed on the inner rotor bearing, on the flange of output shaft, be fixedly connected with magnetic conductive disk, use the collar to install and fix magnet steel on magnetic conductive disk, magnet steel is relative with stator coil but appropriate gap is arranged;
