摘要:
A rim well with integrated flange made of fiber composite as well as to a method for manufacturing same. The flange is formed by inwardly directed protuberances of fiber layers of the rim well, wherein the fiber layers transition to the flange from the rim well without interruption of the fibers. The manufacture is carried out by depositing fiber material on a mold, which corresponds to the contour of the rim well and has a radially circumferential or segmented groove. The fibers are deposited such that the fibers of at least one fiber layer have protuberances directed into the groove. A multipart mold, which makes it possible to reduce the width of the groove and thus a deformation of the protuberances, is preferably used.

Vehicle structures for dissipating and distributing energy associated with a collision are described herein. In one embodiment, a rim includes an inner flange and an outer flange that extend around a periphery of the rim, a rim wall that extends around the periphery of the rim and that extends between the inner flange and the outer flange in the vehicle lateral direction, a drop-well portion that is positioned between the rim wall and the outer flange in the vehicle lateral direction, where the rim wall comprises an increased thickness region that is positioned proximate to the drop-well portion, and where a maximum thickness of the increased thickness region is greater than a maximum thickness of the rim wall positioned outside of the increased thickness region, and at least one spoke extending radially inward from the drop-well portion.

A pneumatic tire having a carcass and a belt reinforcing structure wherein the belt reinforcing structure is a composite belt structure having at least one radially inner spiral layer and at least one zigzag belt reinforcing structure located radially outward of said spiral layer. The zigzag belt width is preferably wider than the spiral layer.

In view of the foregoing, an embodiment herein provides a commercial vehicle wheel comprises of a rim 101, and a disc 102, wherein the rim 101 includes an outer flange 103, an inner flange 104, an outer bead seat 105, an inner bead seat 106, a connecting region 107 for connecting the rim 101 and disc 102, a circumferential mounting groove 108 connected between the connecting region 107 and inner bead seat 106, wherein a valve hole 109 is provided in the outer bead seat 105 for positioning a valve 110, wherein the valve 110 stem is externally projecting outside the disc 102, thereby results in pave the way for achieving larger clearance between the valve and drum/calliper. The outer bead seat is straight across the radius of rim except the valve hole 109 region, and provided without having hump, ledger and/or intermediate ring in the rim 101.

Provided is a pneumatic tire comprising an annular interior surface having a circumference, and an air flow feature. The annular interior surface is adapted for engagement with a wheel, defines an interior surface circumferential direction along the annular interior surface in the direction of the circumference, defines an interior surface meridinal direction tangent to the annular interior surface and perpendicular to the direction of the circumference, and defines an interior surface normal direction mutually perpendicular to both other directions. The air flow feature is engaged with the annular interior surface, adapted to direct a flow of inflation air into a non-circumferential direction, and comprises an air flow feature surface comprising a portion that extends in the interior surface normal direction and the interior surface meridinal direction, and either extends more than 2 millimeters in the interior surface normal direction, or extends in the interior surface circumferential direction.

Embodiments described herein improve airflow around the bicycle wheels by providing for one or more of: (1) a optimum leading edge width of a rim for preventing early stall in cross winds, while still allowing for sufficient stability without undue drag, while not unnecessarily increasing the rotating wheel and drag on the frame; (2) a sidewall shape with a subtle camber angle at the leading, which defines a rate of radius change at the max width of the rim—which further defines the max width and placement along the chord length for optimizing the aerodynamic properties of the rim; (3) a continuous rate of change of curvature at a spoke face, which fundamentally improves the performance and stability by generating a side force at higher yaw angles; and (4) wheel sets with a wider front rim relative to a narrower rear wheel to assist in flow attachment in high crosswind areas.

A pneumatic radial aircraft tire is described having a B/A ranging between 60-70%. The tire may further optionally include a tire bead portion having a Ra/Fr1 relationship which ranges from about 1 to about 2.1. The tire may further optionally include a SW/TS ratio which ranges from about 0.1 to about 0.5, wherein SW is the chafer gauge at area A, TS is the total sidewall rubber gauge at area A, wherein A is defined as the region in the sidewall that has a lower radial endpoint defined by the point of contact between the flange and the tire at inflated, unloaded condition, and an upper radial endpoint AH defined by the tire wheel flange point of contact when the tire is at inflated, and at 200% rated load.
