    摘要： Disclosed are a drive wheel bearing and a method of manufacturing the same. 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.

    摘要： A wheel bearing apparatus has an outer member, an inner member including a wheel hub and at least one inner ring, and double row rolling elements freely rollably contained between the inner and outer raceway surfaces of the inner and outer members via cages. A hardened ring-shaped gear member is mounted on an end of a cylindrical portion of the wheel hub. The gear member is formed with a gear portion on its outer circumference and with a splined portion on its inner circumference. The splined portion engages a hub-splined portion formed on the outer circumference of the cylindrical portion of the wheel hub. A contacting surface of the gear member and a contacting surface of the inner ring that abut against each other are ground. The inner rings are axially immovably secured under a condition where a predetermined amount of a bearing pre-stress is applied to the inner rings via the gear member.

    摘要： A structure for a housing for an axle assembly and method for manufacturing same is disclosed. The housing includes a tube which is formed by casting. The tube is cast having a brake flange, a spring seat, a shock absorber pad, and an outer end for mounting wheel bearings, all of which are integrally formed therewith. The tube is generally hollow and cylindrical in shape, but is formed having an outer circumferential surface which is generally circular in shape and an inner circumferential surface which is generally oval in shape. Thus, the wall thickness of the tube is not uniform about the circumference thereof. Rather, the wall thicknesses of the upper and lower portions of the tube are somewhat greater than the wall thicknesses of the side portions thereof. The wall thicknesses of the upper and lower portions of the tube are sized to accommodate vertically oriented loads induced therein which are generally larger than horizontally oriented loads which are normally encountered in use. The tube is cast from an iron alloy and is subjected to an austempering heat treatment process.
