US Patent:

52194418, Jun 15, 1993
Filed:

Apr 17, 1992
Appl. No.:

7/870355
Inventors:

Victor A. Utykanski - Warren MI
Gary M. Champine - Sterling Hgt's MI
Donald A. Raitzer - Farmington Hills MI
Assignee:

The Budd Company - Troy MI
International Classification:

B60B 2300
US Classification:

301 631
Abstract:

A motor vehicle wheel having an annular wheel rim and a wheel disc in which the flange of the wheel disc is formed with a frustoconical outer surface for engagement with and attachment to a frustoconical inner surface of the wheel rim enabling the disc to be attached to the wheel rim at an inclined, larger diameter section of the wheel rim than the drop center well or the inflation ledge of the rim. This increases the size of the internal envelope formed by the wheel assembly thus increasing clearance for vehicle components within the wheel envelope, such as the brake assembly. Alternatively, a larger brake assembly may be utilized.

US Patent:

51158914, May 26, 1992
Filed:

Dec 17, 1990
Appl. No.:

7/628464
Inventors:

Donald A. Raitzer - Farmington Hills MI
Raymond J. Twisdom - Warren MI
Assignee:

The Budd Company - Troy MI
International Classification:

F16D 6510
US Classification:

188218R
Abstract:

A composite brake drum particularly adapted for motor vehicle applications. The brake drum includes a reiforcement assembly enclosed within the cylindrical portion of the drum. The reinforcement assembly is preferably made from steel wire stock and includes a plurality of circular loops spaced axially within the brake drum cylindrical portion. Axially extending locator wires are mechanically fastened to the reinforcing loops and serve to locate the loops. End portions on the locator wire contact only one of the mold halves forming the mold cavity and enable the device to be essentially self-locating without crossing the parting line of the mold. By not crossing the parting line, the position of the loops is maintained within acceptable tolerance limits from the finished friction surface of the drum.
