Each fastening unit includes a fastening member that extends through the peripheral wall and into a respective one of the spokes for fastening the same, and that has a head disposed outwardly of the outer peripheral wall, and a gasket that is clamped between the head and the outer surface and that is sleeved on the fastening member. For each fastening unit, the respective sealing unit includes an outer sealing layer adhered on an outer face of the fastening member and the outer surface for covering the head and the gasket, and an inner sealing layer adhered on and clamped between the outer surface and the gasket.

A wheel includes a rim and a wheel center interconnected to the rim. The wheel center includes at least one spoke extending from a wheel hub to the rim in a radial direction. The rim includes per the at least one spoke a first contact area and the at least one spoke includes at its outer end a second contact area which in a mounted position is aligned to the first contact area. The at least one spoke includes at least one hollow space extending in the radial direction of the spoke.

The invention relates to a wheel, especially for motor vehicles, comprising a wheel rim and a wheel disc, the wheel rim having a rim base made of fiber composite material. The invention is characterized in that the wheel disc (3, 11, 20, 29, 40) can be indirectly connected to the wheel rim (1), in particular the rim base (2), by means of a connecting element (5, 14, 22, 31, 35, 42) which is designed and associated with the rim base (2) in such a way that the connected wheel disc (3, 11, 20, 29, 40) is not in contact with the rim base (2).

A method for producing a drop centre rim and to a drop centre rim for vehicle wheels of commercial vehicles. The rim has a plurality of zones, which form an inner rim flange and an outer rim flange, an inner steep-tapered bead seat and an outer steep-tapered bead seat and a rim drop centre with a drop centre base, an inner drop centre flank and an outer drop centre flank between the steep-tapered bead seats, wherein one of the zones is provided as a disc attachment region for a wheel disc, and the drop centre rim has at least one partial zone with a reduced wall thickness relative to the other zones. It is envisaged that at least one of the steep-tapered bead seats, preferably both steep-tapered bead seats, has/have a section with a wall thickness reduction of more than 20% relative to the wall thickness in the zone provided as the disc attachment region, wherein the wall thickness reduction is produced during one of the profiling steps.

A process for manufacturing a light-alloy hybrid wheel, implements the following separate operation phases: making a flange with an internal profile capable of constituting a tire bead seat; making a rim with, on one side, an outer profile capable of constituting a tire bead seat and, on the other side, a circular flank for assembly with a part of the flange; and assembling the flange with the rim, at the seat of said flange and the circular flank of the rim. The rim is made according to the following consecutive operations: an operation of manufacturing a circular flank; then an operation of expanding said circular flank to the size of the final rim in a single step; then an operation of cold or hot flospinning of said circular flank so as to obtain the rim in the final shape and profile thereof, comprising a shoulder only on the side that will not be welded to the flange.

A vehicle wheel includes a wheel substrate made of metal and a colored coating layer located on a surface of the wheel substrate. An outer side surface of the wheel includes a first region, a second region, and a groove located between the first and second regions. The colored coating layer covering the wheel substrate is located over the groove. A color of the surface of the wheel substrate is visible at least in the first or second region.

A wheel (10), including a rim (12) and a disc (14) by which the wheel (10) is attachable to a hub of a vehicle, the disc (14) being attachable to the rim (12) by means of generally axially extending fasteners (20), each of which passes through a respective opening (18) of the disc (14) and is received in a respective generally axially extending passage (24) provided in a connecting member (16) of the rim (12), wherein the wheel (10) also includes a spacer (40) having an axial depth to space the disc (14) from the connecting member (16) of the rim (12), the spacer (40) including an opening (42) through which a fastener (20) is receivable to connect the disc (14) to the connecting member (16) of the rim (10), and a locating member (44) which is receivable in a corresponding locating opening (26) in the connecting member of the rim (12).

A wheel includes a rim that is at least partially made from a fiber reinforced plastic. The rim has an inner side extending to the hub region of the wheel and an outer side extending centrifugally away from the hub region of the wheel whereby the outer side includes a well which is interconnected with an outer shoulder by a transition area. A wheel center is interconnected with the inner side of the rim by at least one fastener wherein the at least one fastener penetrates the rim via at least one opening that extends from the inner side of the rim to the outer side of the rim. An annular cover is arranged at the outer side of the rim in a circumferential direction around the wheel and thereby covers the at least one fastener and/or the at least one opening.

An assembled wheel includes a spoke, a T nut, a screw, a fixing ring, a rim, a brake drum. In use, the T nut is installed in the outermost T groove of the spoke; a second boss on a connecting ring fits with the groove on the back of the spoke; the spoke, the connecting ring and the fixing ring are connected together by the first screw; grooves on the outer side of the brake drum fit with a first boss in the right circumferential direction of the fixing ring; and the second screw axially fixes the brake drum in the fixing ring through a spacer.
