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.

In a step of forming a fixing groove for a wheel disk (20), an inner circumferential end of a first hub hole peripheral portion (41) is squeezed by a protruding portion (D21) of a back die (D2) and a dent portion (D31) of a front die (D3). In this manner, a fixing groove (50) is formed in a back surface of the first hub hole peripheral portion (41). Along with this, an excess material is pushed into the dent portion (D31) so that a protrusion (51) is formed on a front surface of the first hub hole peripheral portion (41). Thus, without requiring a step of cutting the excess material, the fixing groove (50) can be formed in a back surface of a hub hole peripheral portion (30).

A two-piece rail wheel assembly is disclosed herein that allows a tire to be replaced without requiring disassembly of the rail vehicle or removal of components directly attached to the axle. In various embodiments, the rail wheel assembly comprises a center wheel hub attached to an axle of a railway vehicle and a tire configured to engage the rail. The center wheel hub and the tire may be bolted together via a stepped (or recessed) interface. When used with in-board bearing configurations, this rail wheel assembly does not require using a press machine, detaching the truck assembly from the rail car, or detaching the wheelset from the truck. When used with out-board bearing configurations, this rail wheel assembly eliminates the need to use a press machine or remove any other components of the wheelset from the axle.

A hybrid wheel including a functional rim, a center disc, and a wheel face insert, wherein the wheel rim and the center disc are made of a specified material, and wherein the wheel face insert is made of a dissimilar material. The wheel face insert can be secured to the center disc by at least one of screws, pins, rivets, or structural adhesive, and/or the wheel face insert can be secured to the functional rim by at least one of screws, pins, rivets, or structural adhesive.

The present invention relates to a castor wheel structure, comprising a wheel part (18) and a castor wheel house (28), on which a transition element can be mounted, such as a spindle structure (1) or a flange structure (2), which again can be mounted on equipment that is to be made mobile, which wheel part (18) is unilaterally suspended and arranged about a substantially horizontal shaft on the castor wheel house (28).

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.

The invention at hand refers to a wheel disc brake assembly comprising a wheel rim, a coupler ring and an annular brake disc arranged in a concentric manner, wherein an outer surface of the coupler ring is connected to an inner surface of the wheel rim and an inner surface of the coupler ring is connected to an outer surface of the annular brake disc. The wheel disc brake assembly further comprises a caliper with at least two brake pads facing each other, wherein the caliper surrounds at least a part of the inner surface of the annular brake disc and the at least two brake pads are configured to press against opposite side faces of the annular brake disc.

A wheel disc adapted for use in a fabricated vehicle wheel includes a steel wheel disc defining an axis and includes a center mounting portion, an outer rim connecting flange, a plurality of radially outwardly extending spokes connecting the center mounting portion to the outer rim connecting flange and a ventilation opening provided between each pair of adjacent spokes. A width defined by a center wall of the spoke is tapered inwardly along a substantial portion of a radial length thereof as the center wall of the spoke extends generally from the center mounting portion to the outer rim connecting flange or wherein a width defined by outer walls of the spoke is tapered inwardly along a substantial portion of a radial length thereof as the outer walls of the spoke extends generally from the center mounting portion to the outer rim connecting flange.

Presented are hybrid metal and fiber-reinforced polymer (FRP) composite wheels for vehicle wheel assemblies, methods for making/using such wheels, and motor vehicles equipped with such wheels. A wheel for a motor vehicle wheel assembly includes a wheel face with multiple spokes that are circumferentially spaced about and project radially outward from a central hub. The central hub rotatably attaches to the vehicle's body, e.g., via a corner module. The wheel face is fabricated, e.g., as a one-piece structure, from an FRP material. A wheel barrel, which circumscribes the wheel face, includes an annular rim that mounts thereon an inflatable tire. The wheel barrel is fabricated, e.g., as a one-piece structure, from a metallic material. Multiple overmold through holes and/or inset tabs are circumferentially spaced about the annular rim. The FRP material extends through and/or surrounds the overmold through holes/inset tabs and thereby mounts the wheel face to the wheel barrel.

A wheel assembly includes a wheel having an outer rim and a hub. A first coupling is applied to the hub. A non-return valve is housed in the first coupling, and a second fitting is applied separably between the hub and the outer rim to connect the outlet of the hub hole with the channel hole.
