Assignee:

Allied Corporation - Morristown NJ

International Classification:

G01J 508

US Classification:

374131

Abstract:

Appl. No.:

5/846003

The Bendix Corporation - Southfield MI

International Classification:

F16D 65847

US Classification:

188264G

Abstract:

A structurally strong heat insulator is depicted in the backing plate and pressure plate regions of an aircraft multiple disc brake assembly. The insulator is constructed from a plurality of perforated metal sheets in order to withstand the large compressive forces experienced during a brake application. The sheets are compiled randomly into an insulating stack which thereby offsets the holes in adjacent sheets. The holes decrease the surface area and the offset increases the heat conduction path, both which reduce the amount of heat cnducted through the stack.

US Classification:

188 732

Abstract:

A series of cap members for covering the drive splines of a plurality of carbon friction discs in a wheel and brake assembly to protect the carbon from oxidization. Each of the cap members have first and second tabs that project into the root sections on the carbon disc between the drive splines. The first tabs on the series of cap members are connected to adjacent second tabs to form a continuous ring member which protects the carbon friction disc from degradation caused by oxidation. During a brake application, the carbon friction disc adjacent the cap member engage a portion of the cap member. Thereafter, the cap member and/or the adjacent carbon friction disc are worn away to maintain the oxidation protection after repeated brake applications.
