Abstract:

In an aircraft multiple disc brake assembly, an excessive total brake torque can be experienced during favorable, dry, conditions. To limit the brake torque to a predetermined maximum, the plurality of conventional brake piston assemblies are modified to provide a pressure responsive surface area which is in an opposing relationship to the braking force. When a predetermined amount of braking torque is experienced, conventional electronics employing strain gauge sensors control a solenoid valve to vent pressurized brake fluid to the opposing surface area thereby reducing the braking force and limiting the total braking torque experienced by the brake assembly to a predetermined maximum amount. The brake pressure is not affected by this system.
