Method for providing wheels for motor vehicles, and associated wheels

A method for providing motor vehicle wheels made of composite material based on carbon fiber includes the steps of dividing each wheel into a plurality of portions having small dimensions; providing a a first portion with the terminal edges designed to mate with corresponding edges of a respective second portion; mating the portions, arranging them subsequently within a respective mold whose shape and dimensions are conjugate with respect to those of the wheel to be manufactured; and bringing the mold and its contents to a predefined temperature. The method further includes injecting into the mold a resin in the liquid state, the resin being injected at high pressure and high temperature, forming the matrix of the composite that constitutes the wheel; maintaining the pressure and temperature of the mold within predefined ranges for a time interval that is required for the at least partial cross-linking of the resin; and extracting the wheel from the mold.

Non-pneumatic tires with strain limiting features

A non-pneumatic tire includes a wheel portion, a tread ring portion, a plurality of flexible spokes extending between and attached to the wheel portion and the tread ring portion, and plurality of bump stops positioned between the wheel portion and the tread ring portion. The bumps stops are configured to limit deformation and/or compressive strain of the plurality of flexible spokes. The plurality of bump stops includes a plurality of tower bump stops, a plurality of triangular-shaped bump stops, and/or a plurality of roof-top shaped bump stops.

HYBRID METAL AND COMPOSITE POLYMER WHEELS FOR MOTOR VEHICLES

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.

RIM FOR A WHEEL OF A VEHICLE
20220024248 · 2022-01-27 ·

A rim for a wheel of a vehicle and having: a central hub; a peripheral ring, on which a tyre can be fitted; and a series of spokes, which are arranged radially and connect the peripheral ring to the central hub. Each spoke has three initial branches, which are distinct and separate from one another, originate from different portions of the central hub and, at a given distance from the central hub, join one another so as to form one single central branch, which ends in the peripheral ring.

Three-layer soft rubber shock absorbing wheel

A three-layer soft rubber shock absorbing wheel including a hub. An outer surface of the hub is bonded with a hard body, a first layer of tread and a second layer of tread having a hardness lower than that of the first layer of tread. The hard body, the first layer of tread, and the second layer of tread are arranged from inside to outside in sequence. The second layer of tread is bonded in a concave surface portion on an outer surface of the first layer of tread. The first layer of tread and the second layer of tread are both elastic bodies. The hard body is configured to have an I-shaped structure body. The three-layer soft rubber shock absorbing wheel is a wheel body made by bonding three layers of materials with different hardness.
