A brake rotor includes a friction portion, a hat portion axially extending from the friction portion and including a top face that is axially displaced from the friction portion and a side wall that extends from the friction portion to the top face, and a nose portion which extends axially from the top face of the hat portion away from the friction portion.

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.

A metal workpiece, such as a wheel, and a method of providing an enhanced corrosion resistant surface coating on an exposed surface of a metal or alloy substrate (such as magnesium). A corrosion resistance basecoat is formed, including generating an oxide layer, and applying a first primer coating onto at least a portion of the oxide layer. The method may further include identifying highest corrosion prone areas on the substrate and designing a support rack that avoids contact with these corrosion prone areas. The method also includes forming a topcoat over at least a portion of the basecoat, by applying a second primer coating onto at least a portion of the first primer coating and depositing a sputtered metallic film onto the second primer coating using a physical vapor deposition technique. A clear coat layer may be applied over the metallic film.

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.

A brake rotor includes a friction portion, a hat portion axially extending from the friction portion and including a top face that is axially displaced from the friction portion and a side wall that extends from the friction portion to the top face, and a nose portion which extends axially from the top face of the hat portion away from the friction portion.

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.

A wheel disc includes a hub located centrally within the wheel disc and defining a wheel axis. The wheel disc further includes an outer circumferential edge and a transition portion radially extending between the hub and the outer circumferential edge. The transition portion has a front surface and a rear surface such that the front surface has a relatively smooth profile and the rear surface has a plurality of concentric ring-shaped curvatures formed therein, thereby providing the transition portion with a variable thickness between the front and rear surfaces.

A wheel assembly for a vehicle includes a face portion and a rim portion. The face portion is formed from an alloy and defines a plurality of spokes extending radially outwardly between a central portion and a proximal bead element. The rim portion is formed of a composite material that defines an annular wall extending between the proximal bead element and a distal bead element. The face portion defines a mating member that is disposed in mating engagement with a rim seat defined by the rim portion. The mating member and the rim seat define a receptor for receiving a pin with said pin including shear resistors oriented to counteract shear forces F between said face portion and the rim portion.
