Abstract
Abstract A wheel especially designed for racing vehicles is described which has an improved structure for cooling both the wheel and any brake or vehicle structure behind the wheel. The wheel includes a circular frame for supporting a ground engaging tire and adapted for securance to the wheel hub or axle of a racing vehicle. A circular array of apertures extends through the side face of the frame adjacent the rim thereof upon which the tire is to be mounted. A fin is associated with each of the apertures and extends outwardly from the side face at a location and in an orientation with respect thereto at which the fin will intercept air flow by the face as the wheel turns and divert such air flow through the aperture.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
185 words
A wheel for a racing vehicle or the like comprising a circular frame for supporting a ground engaging tire and adapted for securance to a wheel hub or axle of a racing vehicle for axial rotation, a plurality of apertures extending through a side face of said frame at spaced locations adjacent the frame outer rim upon which a ground engaging tire is to be mounted, and a plurality of fins extending outwardly of said side face with each of said fins being associated with a corresponding one of said apertures at a location and in an orientation with respect to said frame at which upon axial rotation of said wheel said fin intercepts air flow by said face and diverts said air flow through its associated aperture, said rim being stepped radially inward or said wheel adjacent the side of said face opposite said fin for a distance placing said stepped portion in the path of air flow through said plurality of apertures whereby air caused to flow through said apertures will impinge directly on said stepped portion for enhanced transfer of heat therefrom.
Claim 2
Dependent Claim
185 words
A wheel for a racing vehicle or the like comprising a circular frame for supporting a ground engaging tire and adapted for securance to a wheel hub or axle of a racing vehicle for axial rotation, a plurality of apertures extending through a side face of said frame at spaced locations adjacent the frame outer rim upon which a ground engaging tire is to be mounted, and a plurality of fins extending outwardly of said side face with each of said fins being associated with a corresponding one of said apertures at a location and in an orientation with respect to said frame at which upon axial rotation of said wheel said fin intercepts air flow by said face and diverts said air flow through its associated aperture, said rim being stepped radially inward or said wheel adjacent the side of said face opposite said fin for a distance placing said stepped portion in the path of air flow through said plurality of apertures whereby air caused to flow through said apertures will impinge directly on said stepped portion for enhanced transfer of heat therefrom.
Claim 3
Dependent Claim
43 words
The wheel for a racing vehicle or the like of claim 1 wherein each of said apertures has a circular periphery and each of said fins is curved arcuately along said side face to conform with the circular periphery of its associated aperture.
Claim 4
Dependent Claim
64 words
The wheel for a racing vehicle or the like according to claim 1 wherein said side face of said wheel forms an acute interior angle with said outer rim at the locations at which said apertures extend therethrough whereby air flow through said apertures has a directional component radially outward of said wheel for impingement thereof on the inner circumferential surface of said rim.
Claim 5
Dependent Claim
78 words
The wheel for a racing vehicle or the like of claim 3 wherein, each of said apertures extends radially along said side face toward the center of rotation of said wheel for a greater distance than does said stepped portion so that at least a portion of the air flow therethrough flows by said stepped portion for impingement on brake structure or the like positioned behind said wheel on a racing vehicle to which said wheel is secured.
