Filed:

Dec 3, 1997

Appl. No.:

8/984677

Inventors:

Gary D. Conley - New Boston MI

Assignee:

Hayes Lemmerz International Inc. - Romulus MI

International Classification:

F16D 6510

US Classification:

188218XL

Abstract:

A composite rotor for caliper disc brakes and the like includes an outer friction portion having two ring sections, with a plurality of supports extending therebetween to fixedly interconnect the ring sections in a mutually parallel, spaced apart relationship defining a cavity therebetween. The ring sections have opposite friction surfaces which interface with associated friction members. The rotor also includes an inner hub portion having a central mounting section which mounts the same on a drive member, and a peripheral section cast into the cavity of the outer friction portion to integrally interconnect the inner hub and outer friction portions of the rotor with primarily mechanical bonds formed at an unfused interface.

Abstract:

A fixture for holding a brake drum or other similarly shaped workpiece for machining. The fixture includes a body having a body cavity and a clamping assembly disposed therein. The clamping assembly includes a positioning plate having a plurality of positioning posts secured thereto. The positioning posts are received within fastener apertures formed in the brake drum mounting face for locating the drum within the fixture so that the drum axis is coaxially aligned with the fixture axis for proper machining. The clamping assembly further includes a clamping plate and clamping flange for clamping the mounting face of the brake drum during machining to simulate the compressive forces applied to the drum as it is mounted to a vehicle during operation. The fixture further includes first and second pluralities of chucking assemblies for gripping the body of the brake drum along respective first and second spaced apart planes thereby reducing distortions caused by the cutting tool during machining.
