Abstract

The invention discloses a retarding mechanism with a hub and a brushless motor, relating to a retarding mechanism on a self-balanced two-wheel electromobile, comprising a brushless motor, a hub mechanism and a planetary reducer, wherein the brushless motor, the hub mechanism and the planetary reducer are assembled into a whole; the brushless motor is in transmission connection with the planetary reducer; the hub mechanism comprises an inner hub, an outer hub and a tyre, wherein the inner hub and the outer hub are provided with connection lugs inserted in a groove of the tyre; and the planetary reducer is inserted on the inner hub and comprises an output shaft, a plurality of planet gears, a plurality of bearings installed on the output shaft, a reducer end cover and an inner gear ring meshed with the planet gear, wherein the output shaft is connected with the inner hub in a flange connection manner. The retarding mechanism has the advantages of reasonable design, compact and simple structure, high transmission efficiency, low noise and long service life.

Description

technical field [0001] The invention relates to a geared motor driving mechanism, in particular to a geared motor driving mechanism used in a self-balancing two-wheeled electric vehicle. Background technique [0002] Self-balancing two-wheeled electric vehicle is a kind of electric vehicle with tires arranged in parallel on the left and right, and adopts the principle of inverted pendulum to realize self-balancing electric vehicle; it uses the built-in gyroscope and acceleration sensor in the vehicle body to detect the transformation of the center of gravity between the human body and the vehicle, so as to control the vehicle The direction and speed of the motor, the high speed output by the motor is transformed into an appropriate low speed through the reducer, which requires the reducer to realize the speed change stably and accurately. [0003] In the current self-balancing two-wheeled electric vehicles, the reducer mechanism is placed on both sides of the vehicle body, w...
