Abstract

The present invention provides a motor and an electric vehicle with the same. An inner rotor (10) of the motor serves as a planet gear carrier to assemble a planet gear (12), an outer gear ring (9) isfixedly assembled with the inner wall of an outer rotor (2) of the motor, a sun gear (11) is assembled with a central shaft (5) of the motor through a one-way clutch or a bearing, and a transmissionsleeve (6) is arranged on the sun gear (11) and extends out of the outer rotor (2). The transmission sleeve (6) and the sun gear (11) are integrated or fixedly connected; one end of the transmission sleeve (6), which extends out of the motor outer rotor (2), of the sun gear (11) is fixedly provided with a brake disc (4) of the sun gear (11); and one end cover of the motor outer rotor (2) is assembled on the transmission sleeve (6) of the sun gear (11) through a bearing (8), and the other end cover is assembled with the 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...
