The drive wheel bearing includes: a wheel hub which is integrally and rotatably fastened to a vehicle wheel; an inner race which is fitted with the wheel hub and integrally and rotatably coupled to the wheel hub; an outer race which rotatably supports the wheel hub and the inner race in a state in which the wheel hub and the inner race are fitted into the outer race; rolling elements which are interposed between the outer race and the wheel hub and between the outer race and the inner race; and a constant velocity joint which is integrally and rotatably connected to the wheel hub or the inner race by means of a face spline in order to receive power from an engine and transmit the received power to the vehicle wheel, in which the face spline of each of the wheel hub and the constant velocity joint have a structure in which teeth having the same size and tooth grooves having the same size radially extend, and are alternately and continuously arranged in a circumferential direction, and as a result, it is possible to smoothly transmit rotational power of the engine to the vehicle wheel through the wheel bearing.

Disclosed is a wheel bearing assembly comprising a wheel hub fastened to a vehicle wheel so as to rotate as a unit and having a plurality of fastening protrusion portions, and a brake disc having a plurality of fastening protrusion portions respectively fastened to the plurality of fastening protrusion portions of the wheel hub. Thus, the wheel bearing assembly may facilitate weight reduction and improvement in ease of assembly, and enhance run-out properties of sliding surfaces of the brake disc.

An in-vehicle detection device includes a cable that includes a plurality of insulated electric wires that are formed by covering a central conductor with an insulator, and a sheath that collectively covers the insulated electric wires, a sensor that includes a sensor main body including a detection element, and a lead wire that is led from the sensor main body and connected to the central conductor, and a fixing member that includes a tubular portion to house the sensor and fixes the sensor and the cable to each other. The fixing member holds the insulated electric wires that are exposed from the sheath in a bent state thereof between an end of the sheath and the lead wire. A central axis of a part of the sheath that is held by the fixing member intersects with a central axis of the tubular portion at a predetermined angle.

A method for axially preloading a bearing hub assembly having a rotatable hub, provided with rolling tracks and a bearing unit having a stationary radially outer ring, provided with rolling tracks, and a double row of rolling bodies disposed between the radially outer ring and the hub. The method requires the use of a bias unit and provides the following steps: a) feeding to an assembly station a hub bearing assembly, already assembled; b) verifying the value of the interference (C) between the radially outer ring and the bias unit; c) exerting an axial force (F) radially on the outer ring for the bias unit to deform under compression the radially outer ring that in turn will transmit a force to the rolling bodies via the raceways.
