Abstract

The invention relates to the field of hub motor integrated wheels, and discloses a drive-brake integrated electric wheel integrating a disc hub motor and a reducer, including an external rim, a disc motor, a reducer and a brake disc installed in the rim, and Including the main shaft, the disc motor includes a stator and a rotor assembly. The rotor assembly is connected to the main shaft and rotates around the main shaft. The reducer is installed on the main shaft; the rotor assembly is connected to the input end of the reducer to drive the reducer to work, and the rim is connected to the output end of the reducer. To achieve rotation, the stator assembly is powered to drive the rotor assembly to rotate and drive the reducer to run. The output end of the reducer rotates around the main shaft through the second bearing arranged on the main shaft, and the output end of the reducer drives the rim to rotate; the rotor assembly includes a left rotor and a right rotation The stator is arranged between the left rotor and the right rotor, and the left rotor and the right rotor are fixedly connected. The device has the advantages of high degree of integration, compact structure, and easy maintenance.

Description

technical field [0001] The invention relates to the field of in-wheel motors, in particular to a drive-brake integrated electric wheel integrating a disc-type in-wheel motor and a reducer. Background technique [0002] Chinese invention patent 200910137765.9 discloses an integrated in-wheel motor, which discloses a technical solution: including a motor shaft and a stator fixed on it, the outer casing of the stator is provided with a rotor assembly shell, and the front and rear ends of the rotor assembly shell pass through the rotor assembly end cover and The bearing can be rotatably fixed on the motor shaft, and the two ends of the motor shaft protrude outside the end cover of the rotor assembly to form a long end and a short end. The outer side of the end cover of the rotor assembly is fixed with a bearing end cover, which covers the short end of the motor shaft , the middle part of the bearing end cover is protrudingly provided with a bearing end cover shaft, which protrud...
