Electrodynamic hub wheel with continuous flying head

Abstract

The invention relates to a combined fly integral electric hub wheel which consists of a plurality of main parts, namely, a main spindle, a motor fixed on the main spindle, particularly coreless disk motor, a reducer, a clutch, an outer rotor (shell of a hub) provided with a combined fly head, and a combined fly wheel, wherein, the stator shell of the disk motor is fixed on the main spindle and cannot rotate and the stator is provided with a stator coil; an output shaft is connected and fixed with a guide magnetic disk on which a steel magnet is fixed; one side of the outer rotor is provided with a hanging screw and the other side of the outer rotor is provided with the combined fly head; the combined fly head is of cylinder and contains a reset spring, a ratchet switch wheel and a fly wheel stopper in sequence and is provided with a locating axle bumper; the fly wheel can be a chain wheel or a gear; when wheel diameter is relatively large, the spoke of the outer rotor can adopt different forms according to requirements, and when the wheel diameter is relatively small, especially is as small as 8in, the spoke on the shell of the hub is spared and a felly is directly connected to the shell of the hub to form a super small integral electric hub wheel.

Description

Technical field [0001] The invention relates to a brand-new electric hub wheel technology. Background technique [0002] As we all know, there is an insurmountable obstacle in the miniaturization of electric bicycles-the electric hub with a large motor hanging on a large flywheel. The wheel diameter of electric vehicles (including electric bicycles, electric tricycles, electric disabled vehicles, etc.), at present, the best size at home and abroad is more than 22.5in, because the smallest flywheel attached to a pedal-assisted electric vehicle is 16 teeth, and 48 inches is used. With a large wheel, the speed index of a 22.5in electric bike is 67.5, which is far inferior to 78 for a 26in bike. If the wheel diameter is as small as 16in, the speed index is only 48, and riding is like a baby bike. Not to mention that the popular DC brushless permanent magnet motors have iron cores and thick coils, and are extremely bulky. Therefore, it is impossible to miniaturize the electric ...

AI Technical Summary

Problems solved by technology

Therefore, it is impossible to miniaturize the electric vehicle with pedal assist function by using existing technology

Although the Chinese invention patent hub motor (ZL2005101125005) has given a solution, the technical improvement is minimal. The first reason is to reduce the sprocket from 16 teeth to 14 teeth. The second reason is that the old motor structure has not been improved. Can only slightly increase the speed of large and heavy electric bicycles
