The invention relates to a wheel assembly integrating a brake and a hub motor, and belongs to the technical field of electric wheels. The rotor is fixedly mounted in the cavity of the rim through a fixing piece; the wheel shaft is fixedly installed in the cavity of the rim through a fixing piece, and the wheel shaft is arranged in the rotor and used for forming a jointly rotating or static whole with the rotor and the rim; the hub bearing is rotationally mounted on the axle; the stator is mounted in the cavity of the rotor, is connected with the hub bearing and is used for rotating relative to the wheel shaft; the brake disc is mounted on the wheel shaft; the hub motor end cover is fixedly arranged on the rotor and is used for rotating along with the rotor; and the steering connecting piece is fixedly arranged on the stator and is used for connecting a suspension system. According to the wheel assembly provided by the invention, the hub motor is supported by the hub bearing, so that the stress problem of the hub motor is solved, and the driving safety of an automobile is ensured; occupation of axial space is reduced, and steering and arrangement of a suspension system are facilitated.
