Electronic brake-integrated in-wheel motor driving device

An electronic brake-integrated in-wheel motor driving device, comprising:

• a circular rim, an outer wheel of which is surrounded by a tire, which is coupled to the tire, which is provided with a hollow portion therein, through which a shaft passes and to which the shaft is coupled;
• a motor assembly that comprises a stator inserted into the rim, and a rotor disposed to surround and wrap the stator and configured to rotate outside the stator through supply of power, and that connects to the shaft through a stator hub provided in the stator;
• an electronic brake disposed to face the motor assembly and operating to stop rotation of the rotor;
• a brake mounting jig coupled to the stator hub, configured to accommodate the electronic brake, coupled to the electronic brake and provided with a bearing between the brake mounting jig and the rim;
• a first cover coupled to one side of the rim to seal the motor assembly and to support the shaft;
• and
• a second cover coupled to the other side of the rim to seal the electronic brake accommodated in the brake mounting jig,
• the electronic brake, comprising:
• an electronic brake rotor coupled and fixed to the second cover, and configured to stop rotating by an electromagnetic force when a braking signal is supplied;
• and
• an electronic brake stator configured to face the electronic brake rotor, coupled to the electronic brake rotor through a side opposite to the side of the electronic brake rotor, to which the second cover is coupled, and coupled to the brake mounting jig,
• wherein the electronic brake rotor is provided with a coupling for a coupling with the second cover, and
• the electronic brake rotor is inserted into a circular accommodation groove provided in the second cover.
