摘要： A forged hollow axle, particularly a steerable axle, is designed for a commercial vehicle. The axle has a main longitudinal extension in a y-direction, a width in an x-direction and a height in a z-direction and is composed of at least two half shells fixedly joined at an interface which extends along its longitudinal extension. A material thickness in one or both of the half shells is distributed in the main longitudinal extension and in one or both of width and height to provide a predetermined relation of a torsional stiffness and a bending stiffness in one or more spatial directions in one or more axle sections.

摘要： When an outer circumference of a clamping portion 25 and an outer circumference of a circular outer circumference 26 are restrained by a die 6 while inserting a non-circular punch 5 into a circular hole 28, paddings 27, 27 are pressed by a semi-circular inner circumference of the die 6 to thereby be forced into interior of the circular hole 28. The volume of the paddings 27, 27 is set to be substantially the same as a volume obtained by subtracting the volume of a non-circular hole 23 in an extension shaft 2 from the volume of the circular hole 28. The circular hole 28 is deformed, and the paddings 27, 27 forced into the circular hole 28 abut with inclined planes 52, 52 of the punch 5, whereby the non-circular hole 23 is formed in the extension shaft 2.

摘要： A wheel bearing device of the invention includes a flanged shaft member that includes a shaft portion to which a rolling bearing is assembled, a fitting shaft portion that is formed on one end side of the shaft portion and that is fitted to a center hole of a wheel, and a plurality of flange portions that extend radially outward on an outer peripheral surface located between the shaft portion and the fitting shaft portion and each of which has a through bolt hole in which a hub bolt for fastening the wheel is arranged. Each flange portion of the wheel bearing device is formed by side extrusion when a forged recess is formed at a center of an end surface of the fitting shaft portion by cold forging. An edge portion of a cross-sectional shape taken perpendicularly to a longitudinal direction of each flange portion is formed in an R-chamfered shape.

摘要： The present invention provides an aluminum alloy forging material having enhanced strength, toughness, and corrosion resistance, and a method of producing the material. An aluminum alloy forging material 1 produced with specified components under specified conditions has an arm portion 2 including a relatively narrow and thick peripheral rib 3 and a thin and relatively wide central web 4 having a thickness of 10 mm or less and having a substantially H-shaped sectional form. In a width-direction section of a maximum stress producing site of the rib 3a, the density of crystals observed in the structure of a sectional portion 7 where the maximum stress is produced, the spacing of grain boundary precipitates and the size and density of dispersed particles observed in the structure of a sectional portion 8 including a parting line, the recrystallization ratio observed in each of the sectional portions 7 and 8 of the rib, and the recrystallization ratio observed in a sectional portion 9 of the web 4a adjacent to the sectional structure of the rib 3a in the width direction are defined for enhancing the strength, toughness, and corrosion resistance of the aluminum alloy forging material.

摘要： The invention relates to cams for constructed camshafts, said cams formed from at least one profiled sheet metal strip (2) produced by rolling and having a thickness which varies in the longitudinal direction thereof and two end regions (2a). Said profiled sheet metal strip (2) is bent or deformed to form the cam blank (1) in such a way that the end regions (2a) thereof are welded to the end regions (2b) of at least one other bent or deformed metal strip (2). The cam blank (1) has recess (A) for receiving a carrying shaft (11), said recess (A) having an inner contour region which is essentially circular or partially circular. The aim of the invention is to create one such cam in such a way that it requires as little raw material as possible, the usable width of the running surface is as large as possible, and it can be connected to the carrying shaft in an especially simple and cost-effective manner by a non-positive and/or positive joining method. To this end, a feeder bevel (8) is formed on the inner contour region.
