A bicycle wheel rim, comprising a wall made of composite material having a plurality of perforated spoke-attachment seats, wherein each perforated seat is delimited by at least one first area comprising an amassment of continuous structural fibers and at least one second area circumferentially spaced apart from said first area and comprising cut structural fibers. A process for manufacturing the aforementioned rim is also disclosed.

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.

A wheel with flexible spokes, including a rim and hub, and spokes between the rim and hub made of fibrous material that causes the spokes to be both lighter in weight and stronger than comparable steel spokes. The spokes are also flexible and resilient such that they can bend while retaining their integrity and strength.

One or more embodiments relate to a device configured to form at least partially at least one disc of a wheel having a rim and a hub support defining an axis of rotation, wherein the device has at least: one central zone; one peripheral zone partially surrounding the central zone; one first portion having at least one first layer and extending into the peripheral zone and into the central zone along a first axis; one second portion having at least one second layer and extending into the peripheral zone and into the central zone along a second axis different from the first axis; and in that the first portion and the second portion are superposed relative to one another at the level of the central zone defining a stack.

An article made by composite material includes a body made of reinforced fiber. The body has at least two opposing sidewalls. A foam component is embeddedly disposed in each sidewall. Owing to the two foam components, the finished composite structure is lightweight and has high mechanical strength.

A vehicle wheel, including a rim, a hub, and a plurality of spokes, a first anchor to connect one of the spokes to one of the rim and hub at a connection interface. One of the spokes is pre-tensioned by a pre-tensioning means. The first anchor may be manipulated between: (i) a released orientation where the connection interface is longitudinally released from the spoke to permit independent longitudinal displacement therebetween; and (ii) an engaged orientation where the connection interface is longitudinally connected to said spoke to limit independent longitudinal displacement between the two and to maintain the pre-tension of said spoke. The pre-tensioning means is discreet from the first anchor.

A wheel with high strength flexible spokes of the present invention, including a rim and hub, and spokes between the rim and hub made of fibrous material that causes the spokes to be both lighter in weight and stronger than comparable steel spokes. The spokes are also flexible and resilient such that they can bend while retaining their integrity and strength. The wheel includes a nipple within the rim that receives the high strength spoke and allows for flexibility in adapting the spoke to wheels having differing shapes and sizes.

A wheel of a vehicle has a rim, a hub portion and at least two spokes connecting the hub portion to the rim. At least one spoke intermediate space between the spokes is at least partially covered by a single-piece cover element. A wing portion of the cover element is deformed axially away from the wheel when heat is supplied. The cover element is connected directly to the wheel, and the single-piece cover element is formed from a single material.

The present disclosure relates to a caster, having a housing, having an axle pin which is arranged in a housing opening which is oriented substantially horizontally, and on which at least one wheel is mounted, having, at the top, a pin opening oriented substantially vertically, for receiving a pivot pin, and having a braking device which brakes the at least one wheel, wherein the housing opening for the axle pin allows limited vertical displaceability of the axle pin and the braking device comprises at least one resilient housing part which acts on the axle pin. In order to provide a mechanically reliable braking device, the braking device is additionally provided with at least one spring element which cooperates with the at least one resilient housing part and amplifies the effect of its braking force and/or increases the mechanical load-bearing capacity of the at least one resilient housing part.

A fiber-composite ventilation flap for a vehicle is made of a laminate formed by at least two individual tiers. At least one of the individual tiers has respective unidirectionally oriented fibers, and wherein the at least two individual tiers are arranged in the laminate in such a way that the fibers thereof are oriented at least predominantly differently to one another. The fibers of the at least two individual tiers are oriented differently to one another in such a way that at least one region of the fiber-composite ventilation flap curves about a predefined primary axis under the influence of heat and is thereby in an open state.
