Abstract:
A method of manufacturing a full face vehicle wheel having a high durability performance, in which the back surface of a wheel disk is provided in advance with an annular joining groove. A peripheral joining end of a wheel rim is provided in advance with an inside slope end surface. The peripheral joining end is seated and positioned on the bottom surface of the annular joining groove. A welding heat confining annular region is produced between the inside groove wall of the annular joining groove and the inside slope end surface. The annular joining groove and the peripheral joining end are joined by welding.
Abstract:
A vehicle wheel includes a substantially circular disc defining opposing first and second surfaces. The disc includes a first region, such as a flange, that is substantially perpendicular to the plane defined by the disc and projects from the first surface, and a second region adjacent to the first region. The second region has a continuous curvature extending toward the center of the disc. The continuous curvature defines a radius of curvature and a center of curvature, both of which being located on a side of the second surface.
Abstract:
A wheel assembly includes a tire having bead seat angle in the range 10° to 12°, preferably 11°, and an aspect ratio of less than 60%. Reduced bounce and improved bead retention is obtained. The flange is curve and supports the sidewall of the tire in flexure to reduce rolling of the bead seat;
Abstract:
The invention relates to a wheel rim made from a light alloy, such as an aluminium-based alloy, comprising a front face (10) and a tyre tread (20) which are welded together. The inventive method of producing the wheel rim (J) comprises the following steps: moulding of the front face (10) with a light alloy; provision of a weldable alloy strip with structural hardening; curving of said strip to produce a generally cylindrical shape; welding of the ends in relation to the curved strip with fusion of the strip material; forming of the strip by necking and/or spinning in order to form the tyre tread (20); and welding of the front face and the tyre tread to one another.
Abstract:
Wheel for an automobile, in which assembly between the sheet metal disc and the wheel rim is effected under the outer seat of the rim by cylindrical fitting. The profile of the rim may be obtained by a flow spinning process.
Abstract:
This invention relates to a full face vehicle wheel including a wheel rim joined to a wheel disc. The disc includes a body having a wheel mounting surface and an outer annular portion which defines an outboard tire bead seat retaining flange of the wheel. The outer annular portion includes an outer surface and an inner surface. The outer surface defines a radially extending outer surface in the region of the outboard tire bead seat retaining flange, and the inner surface defines a radially extending inner fit up surface. The outer annular portion further includes a non-radially extending inner surface spaced directly inwardly of the inner fit up surface. The rim defines an axis and includes an inboard tire bead seat retaining flange, an inboard tire bead seat, an axially extending well, and an outboard tire bead seat which terminates at an extruded inturned flange. The inturned flange includes a radially inwardly extending first outer surface, a non-radially extending second outer surface, an inner surface, and an endmost surface. The radially inwardly extending first outer surface defines an outer control surface. When the outer control surface of the rim is positioned adjacent the inner fit up surface of the disc and the rim and disc joined together by the weld, the non-radially extending second outer surface of the inturned flange contacts at least a portion of the non-radially extending inner surface of said disc to reduce a radial distance of the radially extending outer surface of the disc in the region of the outboard tire bead seat retaining flange.
Abstract:
At least one bimetal tab is disposed in a groove between a wheel disc formed from a first metal and a wheel rim formed from a second metal which is different from the first metal. The bimetal tab is formed by roll bonding a layer of the first metal to a layer of the second metal. The first metal layer of the bimetal tab is adjacent to the wheel disc while the second metal layer of the tab is adjacent to the wheel disc. A spot weld which extends through the bimetal tab secures the wheel disc to the wheel rim.
Abstract:
A two piece wheel having a partial wheel rim mechanically attached to a full face wheel disc by at least one locking pin. The locking pin extends through an aperture formed in a collar extending from an inboard surface of the wheel disc and a corresponding aperture formed through the wheel rim end and is secured by a weld. A resilient material is disposed between the wheel disc and rim end to form an air-tight seal therebetween.
Abstract:
A vehicle wheel including a wheel rim having a central axis and a plurality of generally parallel wheel discs extending across the wheel rim. The wheel discs are spaced axially apart and are generally perpendicular to the central axis. The wheel discs are permanently secured to the wheel rim.
Abstract:
An improved aluminum full face vehicle wheel is disclosed wherein the associated rim includes a uniquely shaped outboard tire bead seat which facilitates the welding of the rim to the associated wheel disc. In particular, the rim includes an axially extending outboard tire bead seat which terminates at a axial endmost surface. The axial endmost surface includes a radially extending first end surface, and a non-radially extending chamfered second end surface. When the axial endmost surface of the rim is positioned against an outboard tire bead seat retaining flange of the disc, the radially extending first end surface of the rim abuts the outboard tire bead seat retaining flange of the disc, and the non-radially extending chamfered second end surface of the rim is spaced from the outboard tire bead seat retaining flange of the disc to form a generally annular groove. The groove receives a weld to join the rim and the disc together and produce the finished aluminum full face vehicle wheel.
