The invention relates to a disc brake for an aircraft wheel, comprising friction discs (), including rotor discs and stator discs, a structure comprising a torsion tube () on which the discs are fitted, a rear plate () which is located at one end of the tube, and a support () for braking actuators () at another end of the tube, the actuators being able to be selectively activated in order to apply a pressing force to the discs. According to the invention, the discs are separated into two groups, including a first group () which can be used alone for taxiing braking operations, and a second group () which can be used alone or in conjunction with the first group for take-off/landing braking operations.

Disc brake for an aircraft wheel

The invention relates to a method of using and renovating a brake disk (), the method comprising steps of using the disk in a plurality of lives and compensating for a reduction in the thickness of the disk after each life by assembling the disk with a complementary portion or by associating the disk with another disk of rotor or stator type if the disk is itself respectively of stator or rotor type.

Method of using and renovating a disk from a stack of disks

The invention relates to a method of managing parking braking in a braking system for a vehicle fitted with at least one electric brake including at least one electric actuator having a pusher actuated by an electric motor for selectively applying a force against friction elements of the brake, the method comprising the steps of:

Method of managing parking braking in a braking system for a vehicle fitted with electric brakes

A method of managing the braking of an aircraft, the aircraft having a plurality of wheels R, . . . , R, each fitted with a brake F, . . . , Fadapted to generate a braking force in response to brake pedalsbeing depressed. The management method comprising the steps of: distributing the wheels fitted with respective brakes in at least two distinct groups G1, G2, G3, G'1, G&#x2032;2, G&#x2032;3; allocating respective relationships to each of the groups of wheels for determining how braking force varies as a function of the depression of the brake pedals; and modifying the distribution of the wheels in response to a predetermined event occurring.

Method of managing the braking of an aircraft

An electric brake for an aircraft wheel comprising a supportformed by a torsion tubeand by an actuator-carrier, a stackof disks mounted around the torsion tube, electromechanical actuatorscarried by the actuator-carrier, each actuator comprising an electric motorand a pusher, the electric motorbeing adapted to move the pusherfacing the stackof disks in order to apply a braking force selectively to the stackof disks; and temperature measurement means for measuring a temperature representative of a temperature that exists in the stackof disks. The temperature measurement means comprises at least one temperature sensorarranged in the pusherof one of the electromechanical actuatorsso as to be located in the immediate proximity of the stackof disks when the pusheris brought into contact therewith.

Electric brake for an aircraft wheel, the brake including an electromechanical actuator fitted with a temperature sensor

A method of managing the braking of an aircraft, the aircraft having a plurality of wheels R, . . . , R, each fitted with a brake F, . . . , Fadapted to generate a braking force in response to brake pedalsbeing depressed. The management method comprising the steps of (1) distributing the wheels fitted with respective brakes in at least two distinct groups G, G, G, G', G&#x2032;, G&#x2032;; (2) allocating respective braking relationships to each of the groups of wheels for determining how braking force varies as a function of the depression of the brake pedals; and (3) acting at predetermined intervals to permutate the allocation of the relationships to the groups in application of a predefined permutation relationship. The method also includes a step of modifying the permutation relationship in response to the occurrence of a predetermined event.
