SYSTEMS AND METHODS FOR REDUCING TEMPERATURE OF A BRAKING ASSEMBLY

A system for reducing a temperature of a braking assembly includes the braking assembly of a wheel assembly, an airflow amplifier, and a conduit. The braking assembly may include a plurality of friction disks. The airflow amplifier may be coupled to the wheel assembly, and the conduit may extend from a compressed gas source to the airflow amplifier. Generally, the airflow amplifier is configured to entrain ambient air (“entrained air”) in response to compressed gas from the compressed gas source flowing to the airflow amplifier via the conduit, according to various embodiments. The airflow amplifier may be configured to direct the entrained air and the compressed gas to the braking assembly to reduce the temperature of the braking assembly.

Aircraft landing gear assembly

An aircraft landing gear includes an axle on which wheel and brake assemblies are mounted. An adaptor member is mounted on the axle and arranged to define a brake rod connection point that is distinct from a conventional brake rod connection point defined by the brake assembly. The adaptor member is coupled to the brake assembly via an adaptor linkage that is arranged to react brake torque but arranged to permit relative movement between the adaptor member and the brake assembly in degrees of freedom which are not required to react brake torque.

Rotor drive key assembly

In some examples, an assembly includes a vehicle wheel that defines an interior and an exterior surface, where the interior surface defines a first protrusion and a second protrusion. The first protrusion defines a first aperture extending in a substantially axial direction. The assembly further includes a rotor drive key on the interior surface, the drive key defining a first and second feature, and the first feature defines a second aperture extending in the substantially axial direction and is configured to align with the first aperture. The assembly includes a fastener configured to be inserted through the first and second aperture in the substantially axial direction to attach the key to the interior surface of the wheel, where the second aperture is configured to form a threaded connection with an end of the fastener. When the fastener is tightened via the threaded connection, the second feature engages the second protrusion.

Aircraft wheel equipped with means for the rotational driving thereof by a drive actuator

An aircraft wheel having a rim having brake discs driving keys (21). The wheel has a rotational driver mechanism (210) which includes a drive gear (211) associated with coupling members (212) of the drive gear to the rim of the wheel. The coupling members are fixed to the rim by fixing members (220) introduced into orifices of the rim extending at an end of the keys which are also used to hold heat shields protecting the rim.

Brake actuator for aircraft wheel hydraulic brake

The invention relates to a brake actuator for an aircraft hydraulic brake, which is intended to be added into one of the cavities of a brake ring, the actuator comprising a liner (1) designed to be housed sealingly in the cavity of the ring, a piston (3) mounted to slide sealingly in the liner along an axis of sliding (X) so as to apply a braking force on friction pads when a fluid is introduced under pressure into the cavity, and having a determined operational travel, a wear compensation device (10) which defines a position to which the piston retreats into the liner by means of a mobile stop (11) that can be moved forward by the piston as a braking force is applied, and an elastic return member (16) returning the piston towards the retracted position bearing against the mobile stop. According to the invention, the mobile stop is reduced to a friction member rubbing against the liner, such that one of the faces of the friction member serves as a stop defining the retracted position of the piston, and the other of the faces serves as a support for the elastic return member, the elastic member having, when compressed, a sufficient increase in force in order to be able to push back the mobile stop in the event that the piston is not in contact with the friction pads while its operational travel is already exhausted.
