Title:
WHEEL DRIVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/203953
Kind Code:
A1
Abstract:
This wheel drive device comprises: a rotary electric machine (12) that is accommodated at the inward side of a cylindrical wheel (11) in the radial direction thereof and that rotates the wheel; and a brake device (13) that has a brake disc (61) and a brake caliper (62) and that generates braking force for the wheel. The rotary electric machine has a rotor (30) and a stator (40) that face each other in the radial direction. A hollow part (48) is provided to the inward side in the radial direction of a magnetic circuit part comprising the rotor and the stator. The brake device is provided in the hollow part such that the brake caliper is fixed to an end surface of the stator in the axial direction thereof and the brake disc rotates integrally with the rotor.
