Appeal No. 1998-1263
Application No. 08/351,993
the brake stack comprising a fist rigid disk capable of
maintaining a clamp load across the brake stack during a high
energy stop that is more uniform than the clamp load across the
brake stack that results when only using a pressure plate of
steel.
Independent claim 10 sets forth a friction device
comprising, inter alia, a plurality of actuators spaced
circumferentially, a brake stack having a front axial end
positioned adjacent to and contacted only at circumferentially
spaced apart locations by said plurality of actuators, the
majority of the disks of the brake stack being formed of a
material that will deform or flow during an anticipated high
energy braking action, the brake stack comprising in sequence
from its front axial end a first rigid disk and a steel pressure
plate, and the first rigid disk being formed of a material
capable of maintaining a clamp load across the brake stack during
a high energy stop that is more uniform than the clamp load
across the brake stack that results when only using a pressure
plate of steel.
