Hub type geared motor

Abstract

The invention provides a hub type geared motor. The hub type geared motor comprises a motor located on an inner layer and a planetary gear train located on the periphery which are configured in an enclosure. Particularly, a rotor of the motor and a planetary gear set are combined into an annular rotor, such that the planetary gear comprises at least one planetary gear set in synchronous rotation with the motor rotor and a fixed inner gear ring and a movable inner gear ring which respectively surround and are in mesh contact with the planetary gear set, wherein the movable inner gear ring serves as output; when the annular rotor rotates, the planetary gear train is driven for revolution and the planetary gear set is driven for autorotation by guiding of the fixed inner gear ring, and further the movable inner gear ring is driven for speed reduction and output, such that the problems that a traditional geared motor merely outputs a limited reduction ratio and the integral configuration space, i.e., the volume is difficultly reduced effectively are improved.

Description

technical field [0001] The invention relates to the combination technology of a motor and a gear reduction mechanism, in particular to a hub type motor reducer. Background technique [0002] A geared motor is an integrated power drive device that combines an electric motor and a gear reduction mechanism, or a non-gear reducer. Generally, under the same driving voltage, if a motor has low speed and high torque output, the volume is usually relatively large, and the production cost is also high. If it is high speed and low torque output, the volume is usually relatively small, and the production cost is also high. Low, and the motor reducer allows the motor to generate high speed and low torque through the reducer to convert it into low speed and high torque through the reducer, providing a large torque output in a relatively small volume, and the hub motor assembled on the vehicle wheel is also have the same characteristics. [0003] Traditional wheel hub motor designs incl...
