The invention relates to a multi-part railway wheel for a railway vehicle, having a wheel tire, having an inner wheel part, having at least one elastic body arranged between the wheel tire and the inner wheel part, which body acts for electrical insulation, by way of which body the wheel tire is supported on the inner wheel part, and having a current bridge that is mounted on an outside end face of the railway wheel which bridge comprises a first contact element that consists of an electrically conductive material and lies against the wheel tire with a contact surface, a second contact element that consists of an electrically conductive material and lies against the inner wheel part with its contact surface and an electrical conductor that connects the contact elements. The inner wheel part consists of a light-metal material, at least in the region in which the contact element of the current bridge, which is assigned to the inner wheel part, lies against the inner wheel part with its contact surface. In order to prevent the risk of the formation of contact corrosion at a contact location, at which a contact element of the current bridge lies against a section of the inner wheel part that consists of a light-metal material, in the case of such a railway wheel, using simple means, the invention proposes forming the contact surface of the contact element that lies against the inner wheel part on a section of the contact element that consists of corrosion-resistant, electrically conductive steel material.

A noncorrosive, water-impermeable gasket is used between a wheel rim and a hub assembly so that they do not corrode together making their separation difficult or impossible. The gasket includes a gasket flange with a gasket bolt pattern that is alignable with a hub bolt pattern of the hub assembly and a rim bolt pattern of the wheel rim.

To provide a railway wheel which is excellent in corrosion fatigue resistance. The railway wheel according to the present embodiment has a chemical composition consisting of: in mass %, C: 0.65 to 0.80%, Si: 0.10 to 1.0%, Mn: 0.10 to 1.0%, P: not more than 0.030%, S: not more than 0.030%, Cr: 0.05 to 0.20%, Sn: 0.005 to 0.50%, Al: 0.010 to 0.050%, N: 0.0020 to 0.015%, Cu: 0 to 0.20%, Ni: 0 to 0.20%, Mo: 0 to 0.20%, V: 0 to 0.20%, Nb: 0 to 0.030%, and Ti: 0 to 0.030%, with the balance being Fe and impurities. A plate portion has a matrix structure composed of pearlite.

The utility model discloses a wheel nut, including a nut body which the outside surface comprises of multiple identical arc surfaces. The arc surface is protruding outward, and the radius of the arc surface is larger than the circumscribed radius of the outside surface of the nut body. The utility model designs the existing square surface of the outer hexagon feature of the wheel nut as an arc surface, which the contact area between the wheel nut and the sleeve and the loading area of the wheel nut can be increased, and then the deformation and looseness of the wheel nut can be avoided effectively, and therefore the service life of the wheel nut can be improved.

A method of assembling a vehicle road wheel includes providing a tool fixture configured to support a press-fit load and arranging on the tool fixture an isolation plate defining a plate fastener aperture and having a locating projection. The method additionally includes arranging on the isolation plate a wheel subassembly having a hub surface and an opposing fastener surface and defining a hub aperture and a wheel fastener aperture, such that the hub surface rests against the isolation plate. The method also includes aligning the hub aperture with the locating projection and the wheel fastener aperture with the plate fastener aperture. The method additionally includes installing an insert into the wheel fastener aperture and engaging the insert with the plate fastener aperture. Furthermore, the method includes applying a load to the insert to press-fit the insert into the isolation plate at the plate fastener aperture and thereby assemble the wheel.

A vent plug for a hub cap is provided. The vent plug includes a cover and base forming a chamber. A vent plug body extends from the base and forms a cavity. A shield is coupled to the vent plug body. The shield comprises an annularly extending disc that traverses the cavity. The shield includes a connecting surface to connect the shield to the vent plug body. The shield provides a lubrication/liquid barrier to inhibit lubrication (or other liquid) from entering the cavity formed by the vent plug body and the chamber. The connection between the shield and the vent plug body allows a gas (typically air) to vent past the shield into the cavity and, when pressure is sufficiently high, to the chamber and eventually atmosphere.

A spring-force adjustable, height-adjustable industrial caster assembly including a mounting plate, a swivel housing that swivels relative to the mounting plate, and a spring assembly having components that are moveable relative to the swivel housing to controllably alter spring deflection and/or caster wheel height, which components can be adjusted by accessing the height-adjustable industrial caster assembly from above, eliminating the need to raise a pallet truck or other moveable assembly to which the caster assembly is coupled, away from the floor to be able to access and adjust the industrial caster assembly.

A cap is provided for covering the threaded end of a removable spindle, having a cover with thread engaging tabs extending from a reservoir basin. The tabs include surface projections for retaining the cap to the spindle threads. The tabs are formed to fit within available slots of a slotted hex nut connected to the spindle. The cap includes a separately formed skirt or guard to make flexible surface contact with the torsion arm or spindle supporting structure. The skirt can include a sacrificial anode region to provide cathodic protection for the spindle threads and spindle retention nut. The skirt is removable from the cap so that the cap can be reused with a new skirt. The cap is formed to be used with existing spindle assemblies and to be reusable.

A bicycle gear having a first coating layer obtained by a plasma electrolytic oxidation treatment and a second coating layer, overlapped on the first coating layer, that is a lubricating substance, preferably a fluoropolymer.

A noncorrosive, water-impermeable gasket is used between a wheel rim and a hub assembly so that they do not corrode together making their separation difficult or impossible. The gasket includes a gasket flange with a gasket bolt pattern that is alignable with a hub bolt pattern of the hub assembly and a rim bolt pattern of the wheel rim.
