The invention relates to a caster for movable objects, and more particularly a bed caster, and at least comprises: a running wheel; a fork receiving said running wheel; a guide tube which is designed to be swivelable relative to the fork via at least one bearing; locking means provided on the fork side; and a braking system which can be brought into operative connection with the running wheel and is designed to block rotation of the wheels, characterised in that the braking system includes a brake shoe, a brake spindle, a guide pin and a cup-shaped guide element, wherein the brake spindle has groove-shaped guides, the cup-shaped guide element is provided with projections, and the projections can be brought into operative connection with the guides of the brake spindle in order to form the anti-rotation means.

A motor vehicle wheel bearing assembly includes a hub configured to be supported by at least one rolling-element bearing and to provide a seat for a wheel. The hub includes a first hollow-cone-shaped element manufactured from light metal and having a first axial end section having a first diameter and a second axial end section having a second, larger, diameter and at least one bearing raceway or raceway support at the first axial end section. The hub also includes a second element extending radially from an end of the first hollow-cone-shaped element, the second element having a radially inner section and a radially outer section. The second axial end section of the first element is connected to the radial outer section of the second element, for example, at a joint.

Wheel hubs for a motor-vehicle wheel hub assemblies provided with a bearing unit in turn which include at least one row of rolling bodies, the wheel hub being provided with at least two sheet-metal elements which are rigidly joined together, wherein a first sheet-metal element forms a raceway for the at least one row of rolling bodies.

A method of manufacturing a large- or medium-sized wheel disk including using a punch or die in a first step of ironing a blank of a flat plate to a first-stage product. The first-stage product having a cylindrical rising portion with an axially non-constant thickness. The rising portion includes a thick portion located at a tip portion of the rising portion and a thickness-reduced portion which is a remaining portion of the rising portion excluding the thick portion. During the first step, only a portion of the blank corresponding to the thickness-reduced portion is ironed.

A wheel disc for a disc wheel, especially for utility vehicles; with an essentially radially extending hub fitting flange and an essentially cylindrical disc edge which can be joined to a wheel rim, and with a transition region extending between the hub fitting flange and the disc edge, wherein the transition region is subdivided into at least five segments (Ai to v) passing into each other or into the hub fitting flange or the disc edge, each of which has an outer end situated closer to the hub fitting flange and an inner end situated closer to the disc edge, wherein neighbouring segments have curvatures with different directions and variable material thickness, with the ratios of the material thicknesses and the ratio of their lengths to heights are chosen as follows:

TABLE-US-00001 Material thickness of Length in axial inner end direction Material thickness of Height in radial outer end direction Segment A.sub.I 0.45-0.7  0.9-1.1 (between hub fitting flange and segment A.sub.II) Segment A.sub.II 0.7-1.0  1.6-1.9 (between A.sub.I and A.sub.III) Segment A.sub.III 0.9-1.25 2.5-2.8 (between A.sub.II and A.sub.IV) Segment A.sub.IV 0.9-1.25 2.8-3.1 (between A.sub.III and A.sub.V) Segment A.sub.V 0.7-1.15 6.0-6.8 (between A.sub.IV and disc edge)

A vehicle rigid axle with an axle beam, at the ends of which axle journals or wheel carriers, are arranged, and trailing arms rigidly attached with a spring bracket for supporting an air-suspension bellow, and a method for manufacturing the vehicle rigid axle. An axle beam section extending between the trailing arms, a trailing arm adjoining the axle beam section and the spring bracket are formed by two shell elements connected to each other, which form a hollow body. In an embodiment, the spring bracket is formed by a lower shell element forming an axle beam section extending between the two trailing arms, and the spring bracket is arranged so that the air-suspension bellow mounted on the spring bracket is penetrated by the central longitudinal axis of the axle beam section. Two shell elements made of sheet metal are formed and joined together to form a hollow body.

Disclosed herein is a wheel, in particular for vehicles, such as motor vehicles, with a rim ring having an opening defined there through, and with a main support at least partially arranged in the opening in the rim ring. The wheel, despite having a low weight, provides adequate rigidity and strength and can be produced in a simple manner, while maintaining design flexibility. The main support of the wheel has a plurality of spokes, and a plurality of covering parts for at least partially covering the spokes, wherein the main support and the covering parts support the rim ring.

A heat shield for an aircraft wheel assembly is made of a heat shield material evenly distributed across the heat shield along both the circumferential and the axial directions. The heat shield material has a high thermal conductivity greater than 30 W/mK. In various embodiments, the thermal conductivity is greater than 85 W/mK. In this manner, thermal flux is maximized throughout the heat shield to distribute heat evenly across the heat shield in both circumferential and axial directions.

Wheel hubs for a motor-vehicle wheel hub assemblies provided with a bearing unit in turn which include at least one row of rolling bodies, the wheel hub being provided with at least two sheet-metal elements which are rigidly joined together, wherein a first sheet-metal element forms a raceway for the at least one row of rolling bodies.

A spoke tension adjustment tool has a longitudinally elongated body with a central longitudinal cavity configured to house an end portion of a spoke. The housing has a longitudinal slit that allows the end portion of the spoke to enter the longitudinal cavity. The longitudinally elongated body has a grip portion and a shaped end portion configured to couple with a stem of a spoke attachment element. The shaped end portion is smaller than the grip portion and smaller than the diameter of a rim spoke attachment hole in which the stem is inserted.
