An in-wheel motor drive assembly (11) includes a motor unit that drivingly rotates a motor-side rotating member, a speed reduction unit that reduces the rotational speed of the motor-side rotating member and transmits the reduced rotation to a wheel-side rotating member, a wheel hub (26) that is fixedly coupled to the wheel-side rotating member, a wheel hub bearing that rotatably supports the wheel hub (26), a casing (12) that covers the motor unit, the speed reduction unit, and the wheel hub bearing, a plurality of sensors (43) that are mounted on the casing (12) and capable of detecting strain generated in the casing (12), and a signal processor (46) that calculates load imposed on a wheel on the basis of strain signals output from the sensors (43).

Provided are a face spline forming apparatus and a face spline forming method, with which fluctuation of an inner diameter of a cup section can be suppressed and a face spline can be formed stably. An outer joint member formed by the face spline forming apparatus and the face spline forming method, and a constant velocity universal joint using the outer joint member thus formed are proposed. The face spline forming apparatus comprises: a punch member (50) having a tooth portion (62) for forming a face spline (28); a pedestal (53) having an end-surface receiving surface (52) for receiving an opening end surface (51) of a cup section (7); and a shaft member (57) having an inner-surface receiving surface (56) for receiving a bottom-wall inner surface (55) of the cup section (7). The opening end surface (51) and the bottom-wall inner surface (52) are brought into a simultaneous pressure receiving state. In this state, the punch member performs rocking motion to form the face spline (28) in a bottom-wall back surface (26a) due to plastic deformation caused by the tooth portion (62) of the punch member (50).

The invention relates to a wheel bearing assembly of a vehicle whose hub is mounted in a wheel carrier via a roller bearing arrangement and has a driver flange having a bearing face which is perpendicular to the rotational axis of the wheel, for a wheel, if appropriate with intermediate positioning of a brake disc, wherein the bearing face of the driver flange describes a plane which intersects the roller bearing arrangement. In this context, the hub forms or supports an inner ring of the roller bearing arrangement, while an outer ring is held in the wheel carrier, and a supporting structure for the driver flange on the outside of the wheel bearing assembly, facing away from the vehicle body, is made to extend around the roller bearing arrangement. As a result, a pressing-in depth of the order of magnitude of zero or several millimetres can be achieved with a customary wheel rim.
