A rim for a vehicle wheel having an inner and an outer rim flange, an inner and an outer rim shoulder, a rim well with well base, inner well flank and an outer well flank, a transition section and an inner hump with a hump peak. The rim is having specific material thickness in the area of the transition section. In order to improve wheels in terms of weight minimization and noise development, the transition section comprises at least one stiffening section with a radially offset wall section, the maximum radial offset of which to the adjoining transition section is greater than the material thickness in the transition section. The stiffening section has a diameter, being equal or greater than the diameter on the well base and smaller than diameter of the hump peak.

A method of manufacturing a lightweight wheel with high strength flexible spokes of the present invention, includes providing a rim and hub, and a plurality of lightweight, flexible and resilient 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 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 rim section 18 is provided with e disk section 20 and is secured to a jig by patting the disk section 20 as the lower side. By allowing a groove section 40 l an engaging section) provided along a circumferential direction of the inner peripheral surface 21 of the rim section 18 to engage with a bent end section 48 of a reinforced member 14 attached from the upper side of the jig, the reinforced member 14 can be easily positioned on the inner peripheral surface 21 of the rim section 18.

A wheel disc includes a wheel mounting portion defining a wheel axis, a plurality of spokes radially extending from the wheel mounting portion, and a rim junction on at least one spoke of the plurality of spokes. The rim junction is at an end of the at least one spoke opposite the wheel mounting portion. A first portion of the rim junction extends in an axial direction. Second and third portions of the rim junction extend in a circumferential direction. The axial direction is parallel to the wheel axis and the circumferential direction is in a plane perpendicular to the wheel axis.

The disclosure refers to a hub for a bicycle running wheel, a bicycle drive system and a bicycle. In an embodiment a hub for a bicycle running wheel includes a hub body and a receiving area configured to receive a force transmission means, wherein the hub body and the receiving area are a single part or are firmly connected together.

The invention relates to a method for producing a fibre composite body (2), in particular at least a part of a wheel, comprising the following steps: providing a mould (4) having at least one female mould part (6) and one male mould part, introducing a fibrous raw material (8) and a binder (10) into the female mould part (6), activating the binder (10) by an energy input (p, T) into the mould (4) to form a mould element (12) which is open to diffusion, joining together the mould element (12) which is open to diffusion and a preform structure (14), supplying a resin, so that the resin infiltrates at least partially into the mould element (12) which is open to diffusion and into the preform structure (14), and curing the resin, so that in this way the fibre composite body (2) is formed without a boundary layer.

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.

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 low impact turf wheel for significantly reducing the adverse effects of frequent travel over turf by a lawn mower includes a wheel rim having an inner and outer surface, a hub arranged within the wheel rim, wherein the hub includes a central portion for mounting the turf wheel, and a plurality of spaced apart stems extending perpendicularly outward from the outer surface of the wheel rim. The stem includes a stem surface extending perpendicularly to the stem and a lug extending radially outward from the stem surface. The lug includes a lug face parallel to the stem surface, wherein the combination of the stem surface and lug face provide a ground contacting tread.

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).
