Title:
IN-WHEEL MOTOR DRIVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/098957
Kind Code:
A1
Abstract:
The problem addressed by the present invention is, without detracting from assembly characteristics, to be able to reduce the dimensions in the axial direction of an in-wheel motor drive device and to increase lightness by suppressing the thickness of an aluminum-alloy housing to a minimum. In the in-wheel motor drive device, the output shaft (24a) of a motor unit (A) and a wheel hub bearing unit (C) are coaxially coupled with a reduction gear (B) therebetween. The in-wheel motor drive device is configured from a single outer peripheral member (22a) that integrally forms the outer peripheral section of the housing of the motor unit (A) and the outer peripheral section of the housing of the reduction gear. An outboard-side end-surface member (22c) is fastened to the outboard-side end surface of the outer peripheral member (22a) by means of bolts (61), and the affixing ring (33) of the wheel hub bearing unit (C) is affixed to the outboard-side end-surface member (22c).
