Abstract

Disclosed in the invention is a planetary gear deceleration integrated motor comprising a housing part, a motor part, and a planetary gear deceleration part. The housing part consists of a motor shell, a main beam plate, and a reduction gearbox shell. The motor part installed in a cavity encircled by the motor shell and the main beam plate by a bearing contains a rotor shaft, a motor rotor, and a motor stator. The planetary gear deceleration installed in a cavity encircled by the reduction gearbox shell and the main beam plate by a bearing includes a sun wheel, a planet wheel, a planet carrier, an overturning clutch, and a power output shaft; the rotator shaft extends into the reduction gearbox shell to drive the sun wheel to make rotation; the sun wheel drives the planet wheel to rotate; the planet wheel drive the planet carrier to make rotation; the overturning clutch sleeves the power output shaft; the planet carrier drives the power output shaft to make rotation by the overturning clutch; and an annular gear arranged in the reduction gearbox shell is engaged with the planet wheel. The motor has advantages of small size, light weight, simple structure, high transmission efficiency, and low manufacturing cost.

Description

technical field [0001] The invention belongs to the technical field of drive motors, and in particular relates to an integrated motor integrated with a planetary gear reduction mechanism, which is mainly used in the fields of electric bicycles and electric motorcycles to provide power sources for them. Background technique [0002] Most of the power sources of today's electric bicycles and electric motorcycles use hub motors. Since the rotor and the wheel are integrated in the in-wheel motor, the motor is destined to be a low-speed motor (rotor speed n<600rpm). Because it is a low-speed motor, under the condition of a certain motor quality, the torque that can be provided is small, which is manifested in the vehicle, that is, the vehicle's climbing ability is weak, and it is difficult to meet the driving requirements of the slope road surface; It is used under various road conditions and traffic conditions. During the driving process of the vehicle, the speed of the vehi...
