US Patent:

6354409, Mar 12, 2002

Filed:

Jan 3, 2001

Appl. No.:

09/754697

Inventors:

Robert S. Ballinger - West Chester OH
Kenneth B. Dunlap - Springfield OH

Assignee:

Delphi Technologies, Inc. - Troy MI

International Classification:

F16D 6512

US Classification:

188218XL

Abstract:

The present invention provides a brake rotor including a central disc portion and an extending portion located at a periphery of the central disc portion. A friction portion having a first friction plate is attached to the extending portion and a second friction plate is attached to the first friction plate. The extending portion can be a âUâ shaped configuration adapted to allow the first friction plate to expand in a radial direction in an amount substantially equal to the second friction plate under a condition of elevated temperature.

International Classification:

F16D 6510

US Classification:

188218XL, 188264 AA

Abstract:

A disc brake including a pair of friction plates arranged coaxially in a parallel, spaced-apart relationship and a plurality of vanes extending between the pair of friction plates, each of the vanes having a proximal end, a distal end and a mid-portion extending between the proximal end and the distal end, at least one of the distal end and the proximal end of at least half the vanes having a first cross-sectional area, the mid-portion having a second cross-sectional area, the first cross-sectional area being substantially greater than the second cross-sectional area. The vanes can include a T-shaped portion adjacent the distal end. The vanes can include an hourglass shaped portion. The vanes may taper from the distal end to the proximal end. The vanes can include a thicker cross-section adjacent a peripheral portion of the rotor.
