Benefits of technology

The present invention provides a simplified method of making various sizes and shapes of rims for spoked wheels without the need for special tooling or machines. The method involves shaping a rim from a solid ring using conventional shop equipment, such as a lathe or mill. The resulting rim is high strength and lightweight, with no welds that could weaken the material. This method allows for the fabrication of solid rims that are sturdy and lightweight, ideal for use in motorcycle racing wheels.

Problems solved by technology

The equipment, rollers, welders, etc. needed to make rims this way is very expensive and difficult to operate.
A variety of prior art patents deal with wheel fabrication, but none indicate a method for forming a rim from a forged ring.

Embodiment Construction

[0030] In FIGS. 1-3, a method of making a wheel rim for a spoked vehicular wheel comprises a first step of forming a solid cylindrical ring 21A from a high strength material, as shown in FIG. 1, a second step of machining the cylindrical ring to shape the cylindrical ring into a vehicular wheel rim 21B, as shown in FIG. 2, the rim configured to support a vehicular tire around an outside perimeter of the rim, and a third step of drilling a series of holes 25 around an inner perimeter 24 of the rim, as shown in FIG. 3, to receive a series of spokes from a wheel hub in the series of holes or, attaching spoke material(s) to the hub and rim in mechanically safe ways such as brazing, rivets, welding, pinning etc.

[0031] The first step comprises forming a solid one-piece non-welded cylindrical ring 21A by forging, hot stamping, hot rolling, or hammering a solid block of high strength material into a cylindrical ring or casting a molten high strength material into a cylindrical ring, or ext...

Abstract

A solid forged cylindrical ring with no welds is machined to form a cycle wheel rim for a spoked wheel. Holes are drilled in the inner perimeter of the rim to receive spokes from the hub. This process can produce rims used an many other forms of wheel assemblies.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a method of making wheel rims and particularly to a method of making a rim for a spoked motorcycle racing wheel from a forged aluminum ring that is machined to shape the rim and drilled to form holes for spokes which attach the rim to the hub, thereby creating a sturdy and lightweight one-piece solid wheel rim. [0003] 2. Description of the Prior Art [0004] Motorcycle racing wheels generally comprise a central cylindrical hub that centrally anchors a plurality of spokes or other wheel supporting elements attached to a circularly peripheral rim that ultimately supports a tire thereabout. [0005] Motorcycle wheels rims were typically formed by running sheet stock through rolling machines to roll metal strips and then forming those strips into a hoop and butt welding the two ends together, thereby forming the rim. Most rims were rolled from flat steel strips into shapes (profiles) that ho...
