Abstract:
A wheel assembly includes a tire, having each bead seat angle in the range of 10 degree to 12 degree with respect to the axis of rotation, preferably 11 degree, and an aspect ratio of less than 60%, and a wheel rim, having a circumfurential well and a bead support surface angle also in the range of 10 degree to 12 degree, each bead support surface terminating in an upstanding flange overlapping a radially inner portion of the tire to support the sidewall of the tire. The flanges may be part circular in cross section defining a segment of approximately 135 degree, the radius of curvature being greater than 0.5 inches and preferably 0.75 inches.
Abstract:
The invention related to a method for producing a rim for a pneumatic tire. A rim base with a rear rim flange is produced from a ring-shaped blank by exerting pressure. Said rim base is then connected to a bowl of a rim at the side thereof facing away from the rear rim flange. In order to produce said rim base, the blank is inserted into a compression mould which is embodied as a cavity and is pressed against the at least partially contoured interior of the compression mould by means of at least one compression roll.
Abstract:
The present invention relates to a full face wheel comprising a full face wheel disc and a partial wheel rim. The wheel disc has an annular inboard portion. The wheel rim has an annular outboard end. A chemical bond is formed between the outboard end of the wheel rim and the inboard portion of the wheel disc to secure the wheel rim to the wheel disc.
Abstract:
An improved method for forming a vehicle wheel includes the steps of steps of: (a) providing a wheel rim defining a rim axis and including a generally axially extending well portion and a pair of opposed ends, one of the ends including an inboard tire bead seat retaining flange and an inboard tire bead seat, and the other end including an outboard tire bead seat; (b) providing a generally circular wheel disc blank defining a disc axis, the disc blank including an inner annular wheel mounting portion and an outer annular portion; (c) subjecting the wheel disc blank to a series of metal forming operations to produce a finished disc having a final profile, the finished wheel disc having an outer annular portion, an inner annular wheel mounting portion, and an intermediate portion having a generally convex profile; and (d) joining the finished wheel disc to the wheel rim to produce a fabricated vehicle wheel.
Abstract:
A unique integrated wheel is disclosed wherein a groove is formed with an angled surface to facilitate the flow of a weld material. A rim extends into the groove and has surfaces which act in conjunction with the surface of the groove to provide proper positioning and a secure connection. In addition, a method of forming the disk is disclosed.
Abstract:
A method for manufacturing a vehicle wheel includes the steps of providing a wheel rim and a spider and positioning the wheel rim and the spider adjacent each other. The wheel rim and the spider are then friction welded to each other. Subsequently, a portion of the spider is locked down onto the wheel rim by electromagnetic forming. Preferably, one end of the rim is positioned in a cavity formed in the spider. During friction welding, the upset material of the rim fills the cavity of the spider. Subsequently, while the metal is still relatively fluid, a flange of the spider is locked down onto the wheel rim by electromagnetic forming to secure the wheel rim and spider together.
Abstract:
A multi-piece, non-take-apart vehicle wheel disc and rim assembly and method of making the same. The wheel rim has a disc mounting flange extending radially inwardly of the rim which radially overlaps the disc. The disc and rim are each finish formed prior to assembly and each have a set of assembly-mounting holes extending parallel to the wheel axis which are generally registered in initial assembly. One assembly hole set is preformed slightly larger in diameter than the other. The rim is fixtured on an assembly apparatus to orient the average axis of the rim bead seats on a predetermined first axis of the apparatus. Then the disc is placed loosely on the rim with the sets of disc and rim assembly holes generally registered. Then the disc is precision located relative to the rim by a locating means to align the axes of the disc bolt holes and/or center pilot opening on a predetermined second axis of the apparatus by lateral bodily shifting of the disc radially relative to the rim to accomplish such alignment as necessary. Assembly fasteners are inserted in the registering assembly holes, and then, while so fixtured and located, the disc and rim are permanently fixed together by permanently fixing the fasteners in a non-take-apart mode.
Abstract:
A multi-piece, non-take-apart full-face vehicle wheel assembly having a multiple-part disc in which a wheel mounting disc center part and a disc outer part are each made separately from one another. Each disc part has an annular connector flange formed respectively at the inner and outer peripheries thereof engaging one another in assembly and permanently secured to join the disc parts. Various types of flange joints and fastening systems are employed to join the flanges, including welding systems and mechanical fastening systems. In one joint embodiment the connector flanges of the disc outer part and center part have either conical or cylindrical shape and extend respectively inboard and outboard of said wheel assembly and slidably telescopically overlap with a press fit in assembly. In another joint embodiment the overlapping flanges of the disc center and outer parts extend generally radially of the wheel assembly. In most of the disclosed embodiments the rim has an annular flange extending radially inwardly therefrom in the vicinity of the rim outboard bead seat, and the disc outer part radially overlaps the rim flange. A second joint permanently secures the rim flange and disc outer part together circumferential around the same. The rim may be made from rolled ferrous or non-ferrous sheet metal, or as a machined casting, forging or extrusion of a light metal alloy. The disc outer part and center part are separately manufactured as sheet metal stampings from materials such as stainless, HSLA, or mild carbon steels or non-ferrous light metal alloys.
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 an 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.
Abstract:
An automotive vehicle wheel of light alloy including a main disk (21) and a second disk (22) having bosses (25, 46) respectively for attachment to a hub (26) of an axle, peripheral edges (23, 42) for attachment to a rim (R) of the wheel, vent holes (28, 52) formed in intermediate regions (27, 51) between the bosses (25, 46) and the peripheral edges (23, 42) of the disks and an adapter plate (A) for attaching the disks to the hub (26) for rotation as a unit about an axis of rotation (0--0). The adapter plate includes threaded holes provided normal to a conical surface to receive screw clamping devices for securing the disks which extend at an angle (.theta.) relative to the axis of rotation (0--0).
