Title:
VEHICLE POWER DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/078217
Kind Code:
A1
Abstract:
A vehicle power device (1) is provided with: a wheel bearing (2); a motor generator (3); and a rotation detector (27) that detects the rotational angle or the rotational speed of a rotating wheel (5) with respect to a fixed wheel (4) of the wheel bearing (2). A stator (18) and a rotor (19) of the motor generator (3) are smaller in diameter than an outer peripheral part (12b) of a brake rotor (12), and the entire motor generator (3) excluding a mounting part mounted to a hub flange (7) is positioned within an axial-direction range (L1) between the hub flange (7) and the outboard side-surface of a suspension frame component (8). The rotation detector (27) is positioned inside a hollow part of the stator (18).
