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.

A bicycle hub shaft includes a first shaft section made of a first material and inserted into a sprocket seat; and a second shaft section made of a second material. The strength of the first material is stronger than that of the second material. The first shaft section has one end connected to one end of the second shaft section. The bicycle hub shaft is formed by the first and second shaft sections, instead of being integrally formed. Besides, the strength of the first shaft section is stronger than the second shaft section, so that the first shaft section inserted in the sprocket seat has a higher structural strength, thus improving the strength of the bicycle hub shaft and the load capacity of the sprocket seat as well.

Provided is a non-pneumatic tire in which a plurality of curved sections (21d) to (21 f) and (22d) to (22f) curved inward in a tire circumferential direction are formed at elastic connecting plates (21) and (22) in an extension direction in which the elastic connecting plates (21) and (22) extend when seen in a tire side view such that curved directions are alternately opposite to each other in the extension direction, outer curved sections (21e) and (22e), inner curved sections (21d) and (22d), and extension sections (21i) (22i) extending throughout both of the curved sections and in which inflection sections (21g) and (22g) formed between both of the curved sections are disposed, are formed at the elastic connecting plates (21) and (22), and the extension sections (21i) and (22i) extend along reference lines having radii of curvature larger than that of the outer curved sections (21e) and (22e) and the inner curved sections (21d) and (22d) when seen in the tire side view and extend from first end portions (21a) and (22a) of the elastic connecting plates (21) and (22) connected to an outer tubular body (13) to arrive at a central portion in at least the extension direction.

The invention relates to a vehicle wheel comprising a wheel rim, a wheel disc and at least one connecting element that connects the wheel disc and the wheel rim, wherein the connecting element is guided through a through-hole of the wheel rim and is joined in a joining channel of the wheel disc. According to the invention, an elongated sleeve (4, 4.1, 4.2, 4.3) is provided that surrounds the connecting element (3, 3.1, 3.2) coaxially, which sleeve is designed and arranged in such a way that at least part of said sleeve interlockingly extends into a corresponding recess (7) of the wheel rim (1.1, 1.2) and into a corresponding recess (8) of the wheel disc (2.1).

The omnidirectional wheel includes a first support portion which rotates around a rotation axis line, a second support portion which rotates together with the first plate-like member, a number of support shafts respectively supporting a number of rollers, and a number of support plates fixed to the first and the second support portions and which support one or more of the support shafts between the first and second support portions.

A hub bearing module for a lightweight suspension upright or knuckle of a vehicle, the hub bearing module including a wheel bearing and a bearing connection interface to the suspension upright or knuckle, the bearing connection interface being arranged coaxial with the rolling bearing and including a first sleeve element and a second sleeve element arranged radially outside the first sleeve element and including a composite, preferably BMC (Bulk Molding Compound) annular body having a radially inner lateral surface mechanically coupled to the first sleeve element and a radially outer lateral surface configured to mechanically and chemically couple with the suspension upright or knuckle.

A road wheel for a vehicle includes a face portion and a rim portion. The face portion is formed from a metallic alloy and defines a central portion plurality of spokes extending between the central portion and a proximal bead element. The rim portion is formed from a composite material and defines an annular wall circumscribing a wheel axis extending to a distal bead element from said face portion. The proximal bead element is defined by the metallic alloy and the distal bead element is defined by the composite. The face portion and the rim portion are interconnected in interlocking engagement.

A vehicle axle includes, an axle gear unit housing and axle tubes adjoining the latter. The axle gear unit housing has an opening which is surrounded by a flange. Threaded blind bore holes extend beyond the thickness of the flange into the region of the wall of the axle gear unit housing which has radially outwardly on the side of the flange facing the axle gear unit housing a wall thickening which extends annularly radially circumferentially along the flange and which is configured in a continuously annular manner or so as to form spot faces partially in the areas of the threaded blind bore holes, wherein a joint flash extends in a central plane along the axle tubes and toward the flange 4 in the region of the axle gear unit housing and at the flange along the radially outer contour of the wall thickening.

Wheel bearing flanges and wheel bearings are disclosed. The wheel bearing flange may include a flange connected to an inner ring of a bearing, the flange having a front surface facing away from the inner ring and a rear surface facing towards the inner ring. A plurality of geometric features may extend from the rear surface in an axial direction and define recessed regions of the flange therebetween. The geometric features may be formed in a pattern and the geometric features may include ribs.

A hub for bicycles with a hub shell rotatably supported relative to a hub axle by roller bearings and a rotor rotatably supported relative to the hub axle by at least two rotor bearings and with a freewheel device with two interacting freewheel components namely, a hub-side freewheel component and a rotor-side freewheel component. The two freewheel components are movable relative to one another in the axial direction between a freewheel position and an intermeshing engaging position in which a driving torque can be transmitted. The hub-side freewheel component is compact in configuration and a hub bearing to rotatably support the hub shell is integrated and configured therein. An outer ring of the hub bearing is configured in an axial body section of the hub-side freewheel component. A sealing unit protects the interior of the hub bearing from the entry of dirt and water.
