Caliper braking system for aircraft landing gear having a plurality of brake disk clamping zones

A wheeled landing gear, wherein the wheeled landing gear includes a braking system comprising:

• an actuator;
• a caliper having a plurality of supports, each support having at least one pad;
• a rim movable in rotation about an axis of rotation;
• and
• a brake disk floatingly mounted relative to the rim, the brake disk including at least one constraining element co-operable with notches in the rim;
• the plurality of supports comprising a stationary inner support, a movable intermediate support that is movable under the action of the actuator, and an outer support hinged relative to the inner support, the brake disk arranged between the intermediate support and the outer support, and the brake disk arranged between the inner support and the outer support, the at least one pad disposed between each support and the brake disk, such that under action of the actuator, the movable intermediate support moves causing movement of the brake disk so that the brake disk is clamped by the at least one pad between the intermediate support and the outer support, and also causes movement of the outer support so that the brake disk is clamped by the at least one pad between the inner support and the outer support.

An aircraft including a wheeled landing gear and wherein the wheeled landing gear includes a braking system comprising:

• an actuator;
• a caliper provided with a plurality of supports, each support including at least one pad;
• a rim movable in rotation about an axis of rotation;
• and
• a brake disk mounted relative to the rim, the brake disk including constraining elements co-operable with notches in the rim;
• the plurality of supports of the at least one caliper comprising a stationary inner support, a movable intermediate support movable in response to action of the actuator, and an outer support hinged relative to the inner support, the brake disk disposed between the intermediate support and the outer support, and between the inner support and the outer support, the at least one pad being positioned between each support and the brake disk, such that under action of the actuator, the movable intermediate support moves causing a first movement of the brake disk so that the brake disk is clamped by the at least one pad between the intermediate support and the outer support, and then continues to move the outer support so that the brake disk is clamped by the at least one pad between the inner support and the outer support.
