An axle end assembly has a wheel brake arrangement and a wheel hub arrangement. The assembly is designed as a preassembled unit with a hollow shaft element on which the wheel brake arrangement and the wheel hub arrangement are disposed.

A dual wheel system includes a first wheel, a second wheel, and a transition plate arranged between the first and second wheels. Each wheel includes a rim with a disk positioned transverse to a longitudinal axis. The disk of the first wheel has a first plurality of holes arranged concentric about the longitudinal axis with a first bolt pattern, and the disk of the second wheel has a second plurality of holes arranged concentric about the longitudinal axis with a second bolt pattern. The transition plate includes an outer ring of holes for fastening the wheels to the transition plate via the first and second plurality of holes, and an inner ring of holes for fastening the transition plate to an axle flange of a work vehicle.

An apex axle truss system includes a first apex axle truss including a sheet of metal that has been bent to form a first substantially vertical wall, second substantially vertical wall, first angled wall, and second angled wall. The first substantially vertical wall is configured to be secured to a first lateral side of an axle housing. The second substantially vertical wall is configured to be secured to a second lateral side of the axle housing. The first angled wall is disposed between the first substantially vertical wall and the second substantially vertical wall. The second angled wall is disposed between the first angled wall and the second substantially vertical wall. The first angled wall and the second angled wall form an apex that is configured to be disposed over an upper surface of the axle housing.

A mounting portion of a disc includes a flat plate portion having a pressing surface to be pressed against a hub of an axle, and a plurality of nut support portions protruding from the flat plate portion to a side opposite to the pressing surface in an axial direction of the disc, and having an annular shape as viewed from the axial direction. A bolt hole is provided to penetrate the nut support portion in the axial direction. The nut support portion includes a bulging portion curving to bulge outward in a radial direction of the nut support portion, and a protruding portion disposed adjacent to the bulging portion in a circumferential direction of the nut support portion, and protruding inward in the radial direction of the nut support portion with respect to the bulging portion.

A vehicle component such as an axle spindle or suspension beam (3) is connected to a tubular vehicle axle (1) by fitting a connector sleeve (2) onto the axle and subjecting the assembly to a crimping operation in which plural depressions (206,2018) are formed by indentation in the connector sleeve and the axle wall at the connection region (11,12) to fix the connector sleeve on the tubular axle. In the described proposals a solid lubricant (4) such as molybdenum disulphide is applied at the connection region between the connector sleeve (2) and axle (1), before crimping. The further vehicle component (3) is then connected to the connector sleeve (2) by welding.

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.

This non-pneumatic tire is provided with a tread ring, a wheel which is arranged radially inside of the tread ring, and spokes which are interposed between the tread ring and the wheel. Further, the wheel has a disc part to which the vehicle shaft is linked, and a rim part which is connected on the inner peripheral side to the disc part and is joined on the outer peripheral side to the spokes. In this configuration, the average thickness (T1) of the disc part is set to be less than the average thickness (T2) of the rim part. In other words, the relation T1<T2 holds.

Vehicle wheel comprising a rim part and a disc part formed from a one-piece sheet metal blank and including a central portion with bolt holes and a plurality of radially extending spoke arrangements merging into a disc edge delimiting together with the spoke arrangements ventilation apertures which extend over the region between the edge webs and the disc edge. In order to create steel wheels with four-hole fixing in which high strength and stiffness are achieved the number of spoke arrangements and of bolt holes is four and these are in each case arranged mirror-symmetrically with respect to a common radial line, with the width of each spoke arrangement narrowing radially towards the outside and each ventilation aperture extending in the circumferential direction over an arc length of more than of the circumference of the disc part. Further, each ventilation aperture is having on a radial line a maximum radial clear width which is equal to or preferably greater than the radial width of the metal portion of the disc part on the same radial line.

A portal-axle of bogies for light rail vehicles, such as for example trams or light rail metros with street running, is described, the light rail vehicles being characterized by a floor, i.e. a walking surface, lowered with respect to the rails. The portal-axle comprises two shoulders equipped with spindles for mounting wheels and with a central portion for structurally connecting the shoulders. Unlike conventional solutions, the central portion is not made by casting or forging, but advantageously is simply defined by at least two bars coupled thereto during the assembly. The bars are easily available on the market at low cost, have lower weight with respect to a traditional forged/cast component and allow modularity and versatility in dimensioning the portal-axle to be obtained.
