Abstract:
A low pressure all terrain vehicle tire 10 features a strapped bead core 20 which comprises distinct layers 30, 32, 34, 36 of filaments 26 positioned relative to one another. The bead core 20 has a substantially square or rectangular cross-section and a radially inward substantially flat base side 44, a radially outermost side 46, an axially inward first side 48, and an axially outward second side 50. The first side 48 intersects the base side 44 at a first edge 54 and forms thereby an included angle .alpha.. The second side 50 intersects the base side 44 at a second edge 56 and forms thereby an included angle .beta.. Angle .alpha. is equal to .beta.. The bead core 20 has perimeter 42 comprising the lengths of the base 44, radially outermost 46, first 48, and second 50 sides. The perimeter 42 defines the bead core area. The width of the bead heel surface 60 is approximately equal to the distance between a hump 80 and an axially inward surface 74 of the wheel flange 76. The bead core base side 44 has a width in the range of 65% to 90% of the rim seat width W and a radially inner diameter about equal to the diameter of the rim hump 80. The bead heal surface 60 has a width in the range of 80% to 125% the rim seat width W.
Abstract:
A tire wheel includes a pair of flanges provided on both axial ends, respectively, a pair of bead seats extending from the flanges axially inwardly, a well provided between these bead seats and concaved radially inwardly of the bead seats, and at least one hump circumferentially extending provided between the well and one of the bead seats and having a seat side inclined surface on a side of the relevant beat seat and a well side inclined surface on a side of the well to form a top as a boundary between both the inclined surfaces. The seat side inclined surface is formed by part of a conical surface intersecting at an angle of 5.degree.-35.degree. with a straight line in parallel with a tire axis. A concaved obtuse corner is formed at a boundary between the seat side inclined surface and the relevant bead seat.
Abstract:
A rim assembly for a bicycle wheel, comprising a rim having generally opposing first and second wall sections configured for mounting a bicycle tire, each of said first and second wall sections comprising an outwardly facing recess and; a rim component located in each recess, wherein each rim component has a lower density than the rim, wherein the rim components do not form part of a braking section of the bicycle wheel.
Abstract:
A rim for a braked aircraft wheel includes an outer circular portion whose ends are terminated flanges for receiving a tire. The outer circular portion is connected by a wheel disk to a hub for fitting on an undercarriage axle in order to rotate about an axis of rotation coinciding with a central axis of the rim. The rim is designed to receive the tire on the outside of the outer circular portion and a brake on the inside of the outer circular portion, the outer circular portion presenting on one side of the wheel disk that is to receive the brake, in a plane containing the central axis of the wheel, a profile that has two slopes forming non-zero angles with the central axis, the two slopes extending in the continuation of one another from the wheel disk to the corresponding flange and flaring towards said corresponding flange.
Abstract:
A vehicle wheel includes a rim having mounted thereon an inflation valve and a tire. The inflation valve is extended by an inflation channel extending through the rim and opening out into a volume of gas defined by the rim and the tire. The inflation valve is arranged in the vicinity of a flange of the rim.
Abstract:
A bicycle rim has rim a pair of rim flanges that defines a tire channel. A rim strip extends across the tire channel. The rim strip includes a pair of flange bumpers configured to cover the rim flanges. The flange bumpers each define a flange channel in which one of the rim flanges is received. A pair of safety humps define corresponding tire seating sections where a tire is seated when inflated. The rim strip further includes a drop seal that seals with the beads of the tire to facilitate seating of the tire during inflation.
Abstract:
The present invention provides a bicycle rim assembly adapted to be coupled to a hub to create a bicycle wheel. The rim assembly includes a rim and a cover coupled to the rim. The rim defines a central plane and comprises an annular inner wall and an annular outer wall cooperating with the inner wall to define a cavity. The rim further includes annular projections spaced laterally relative to the central plane and extending substantially radially outwardly from the outer annular wall. The cover includes sidewalls disposed on lateral sides of the rim adjacent the projections, each sidewall including a lateral inner portion having a lateral thickness. The cover further includes an annular ring portion interconnecting the sidewalls, the annular ring portion including a radial thickness less than the lateral thickness of the lateral inner portion of the sidewalls. Preferably, the rim comprises a metallic material and the cover comprises a non-metallic material. For example, the rim can comprise aluminum or an epoxy matrix composite, and the cover can comprises a polymeric material, such as ultra-high molecular weight polyethylene. In addition, a radial thickness of the entire cover is preferably substantially less than a radial thickness of the entire rim.In one embodiment, the projections include a laterally inwardly facing surface, a laterally outwardly facing surface, and a radially outwardly facing surface. In this embodiment, the cover engages at least a portion of each of the laterally inwardly facing surface, the laterally outwardly facing surface, and the radially outwardly facing surface. Preferably, each annular projection has a smoothly radiused radially outwardly facing surface, and each laterally outwardly facing surface that lies in a radial plane substantially parallel to the central plane.
