Sliding brushless large hub motor

Abstract

A sliding brushless large hub motor is composed of a half-axle hub wheel, a rear wheel bracket, an outer rotor brushless motor, an axle clutch, a manual handle, and a controller. The outer rotor brushless motor is arranged in the hub of the half-axle hub wheel. The axle clutch is arranged in the left half axle of the half-axle hub wheel. Ultra-thin bearings and an adjustable bearing frame are arranged at the outer circle of the left half axle. By renovating the structure of the rear wheel bracket and remotely controlling the axle clutch through the manual handle, simple and effective driving clutch of the sliding brushless large hub motor is realized. All the advantages of a brushless toothless large hub motor and the anti-charging flexible brake function are retained. Moreover, the motor has very low resistance in an idle state and can be easily ridden just like a bicycle under the condition of power failure. The contradiction caused by uncontrollable driving clutch of various existing hub motors is solved. The axle clutch makes full use of the space of the left half axle of the half-axle hub wheel, so that the axial size of the sliding brushless large hub motor is reduced, and the sliding brushless large hub motor is small, light and cheap. The sliding brushless large hub motor is especially suitable for light electric bicycles.

Description

technical field [0001] The invention relates to an electric wheel hub motor, specifically, a sliding brushless large wheel hub motor. Background technique [0002] At present, most of the in-wheel motors used in various electric vehicles on the road are brushless and gearless large in-wheel motors across the country. It has become a A mainstream product in today's market. But it is not perfect, because it is directly driven, has no sliding function, and there is magnetic resistance when the motor is idling, so when the electric car is out of power, human riding is very heavy. Therefore someone installs an overrunning clutch on this motor, for example the application number is: "201120144725. Hub motor, but it loses the flexible braking function of reverse charging, and its structure is complex and costly. Contents of the invention [0003] In order to overcome the shortcomings of the existing brushless and toothless large hub motor, the present invention introduces a sl...
