摘要:
A tyre for vehicle wheels has a pair of beads (5) each having a frusto-conical rest surface (5a) and showing a cross-section profile converging towards the rotation axis of the tyre (1) away from an equatorial plane (X-X) of same. Each bead (5) incorporates an annular anchoring structure (4) comprising an anchoring portion (16) of a flattened profile extending in parallel to the rest surface (5a), and a stiffening portion (12) extending in a radial direction. Associated with the carcass structure (2) is a circumferential centring ridge (20) radially jutting out within the tyre (1) at a crown portion of the latter. Also described is a rim (23) provided with engagement seats (24) the shape of which matches that of the beads (5) and with a guide race (25) conforming in shape to the centring ridge (20).
摘要:
A tire/wheel assembly body enables reduction of road noise while reducing unsprung mass using a light-metal wheel. The tire/wheel assembly body is formed by installing a pneumatic tire on the light-metal wheel with a rigidity index (α) of 35 to 65 (1/rad). In the pneumatic tire, reinforcement layers are arranged at end portions of a belt layer.

An assembly comprising a rim having a substantially cylindrical bearing surface having at least one depression therein, and an annular run-flat support mounted on said bearing surface. The radially inner surface of said support further comprising a protuberance to engage said depression in said rim, and wherein a radially innermost base portion of said support includes a plurality of substantially circumferentially oriented reinforcement elements. Said reinforcement elements are axially spaced apart, and said reinforcement elements are absent in an axial portion of said base portion radially outward of said protuberance.

An identifying mark is disposed in a cast-in recess that is formed in a raw casting that is subsequently transformed into an automotive roadwheel. The mark provides for a unique identification to thereby allow the progress of each wheel through its manufacturing process to be monitored and its manufacturing history to be memorialized. The same identifying mark may be relied upon by the auto manufacturer for similar purposes and by matching each wheel's ID to VIN of the vehicle to which it is mounted, the end user should remain traceable throughout the wheel's service life. The recess is positioned so as to protect the mark disposed therein during the manufacturing process as well during its end use.

The invention relates to a rim for cycles, more particular for bicycles. The invention is also aimed at a tubeless mounted assembly consisting of the said rim and of a tire having in particular two flexible bead wires. According to the invention, the rim consists of two flanges, attached to two seats, intended to receive the beads of a tire, separated from each other by a mounting groove, and, according to the profile of the rim in a radial plane, the bead seats have a generatrix, the axially outer end of which is on a circle of smaller diameter than the diameter of the circle on which the axially inner end is situated, the said generatrix forming an angle with the axis of rotation of the tire of between 15 and 45 degrees.

A bicycle wheel includes a reinforced annular rim that is coupled to a hub via a plurality of spokes. Specifically, the rim includes an outer portion and an inner portion fixedly coupled with the outer portion to form an annular hollow area between the inner and outer portions. Preferably, outer tubular spoke attachment portions are fixedly coupled to the outer portion at outer openings, while inner tubular spoke attachment portions are fixedly coupled to the inner portion at inner openings aligned with the outer openings to define spoke receiving spaces. Preferably, at least the first or second tubular spoke attachment portions are heat fused to the outer or inner portions, respectively. Each spoke receiving space is preferably at least partially threaded with the outer end portions directly threadedly coupled within one of the spoke receiving spaces. The central hub has the inner end portions of the spokes coupled thereto.

Wheel rim comprising two rim seats having different diameters, inclined outwards and extended axially outwards by two humps of small height, the rim seat of smaller diameter being connected axially on the inside to a bearing surface via a truncated conical portion and the rim seat of larger diameter being connected axially on the inside to the said bearing surface by a rib of small or zero height, whose axially interior wall has a generatrix that makes with the rotation axis an angle open radially and axially outwards and at the most equal to 30°, characterised in that the said rib, which has an axially inside wall of axial width at most equal to the axial width of the said second seat is provided circumferentially with at least two transverse grooves of small size.

A large-diameter part, the diameter of which is larger than the diameter in the center, is provided at the edges of a rim via parts having a difference in a level. Curled parts are provided on both edges of the rim by curling the large-diameter part. Each end face of the curled parts is touched to the parts having a difference in a level. The rigidity of the side of the edge of the rim can be enhanced by providing the parts having a difference in a level to the rim. As a result, the rigidity of the whole wheel can be enhanced and in addition, as a disc and the rim are not required to be thickened, the weight of the wheel can be prevented from being increased.
摘要:
A tyre for a vehicle wheel includes a carcass structure, a belt structure, a tread band, and at least one pair of sidewalls. The carcass structure includes at least one circumferential centering ridge jutting out from a crown portion of the carcass structure. Each bead of the tyre includes a rest surface defining, in a direction away from an equatorial plane of the tyre, a profile converging toward the rotation axis of the tyre. A rim for a tyre includes a base body and two seats. Each seat defines an abutment surface facing radially away from a rotation axis of the rim and includes a frustoconical configuration converging away from a median diametrical plane of the rim. The base body further includes at least two opposite radial shoulders disposed to abut against the at least one centering ridge. A vehicle wheel, including the tyre and the rim, is also disclosed.
