Abstract

According to the motor and the electric vehicle provided with the motor, a sun gear (12) is fixedly assembled with an inner rotor (11) of the motor, an outer gear ring (10) is fixedly assembled with the inner wall of an outer rotor (2) of the motor, a planetary gear (13) is assembled on a planetary gear carrier (9), and a transmission sleeve (6) is arranged on the planetary gear carrier (9) and extends out of the outer rotor (2). The transmission sleeve (6) and the planetary gear carrier (9) are integrated or fixedly connected, a planetary gear carrier brake disc (4) is fixed at one end of thetransmission sleeve (6), extending out of the motor outer rotor (2), of the planetary gear carrier (9), and an end cover of the motor outer rotor (2) is assembled on the transmission sleeve (6) of the planetary gear carrier (9) through a bearing (8). One end cover is assembled with a motor central shaft (5) through a bearing.

Description

technical field [0001] The invention relates to a motor and an electric vehicle, in particular to a hub motor equipped with a planetary gear transmission and an electric vehicle equipped with the motor. Background technique [0002] At present, energy recovery electric vehicles are gradually being used. Energy recovery means that when the electric vehicle goes downhill, the drive motor instantly turns into a generator to generate electricity, and the resistance of the electricity generated is used to assist braking, and the generated electricity is used to extend the cruising range. Because the generator has a certain speed requirement when generating electricity, the energy recovery electric vehicles currently on the market use brushless toothed motors, but in order not to affect the sliding of electric vehicles, the planetary gears inside the brushless toothed motors A one-way clutch is added to the transmission, which means that the inner rotor of the motor can only drive...
