Abstract: An aircraft wheel comprising two half-wheels (1, 2) assembled together by means of bolt fasteners (10; 110) clamping together disks of the half-wheels, each bolt fastener comprising a bolt (11; 111) with an end forming a screw head (12; 112) and a threaded end (13; 113) for receiving a nut (14; 114), the wheel also being fitted with drive keys (20; 120) that are fitted to one of the half-wheels for driving brake disks in rotation, the wheel being characterized in that each drive key has a first end (23; 123) that is shaped to co-operate with the screw head of one of the bolts so that said first end is held and prevented from moving when the key is in place on the wheel.

Abstract: A brake actuator for an aircraft hydraulic brake, insertable in a cavity of a brake ring. The actuator comprises 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 when a fluid is introduced under pressure into the cavity, and a wear compensation device (10) which defines a position to which the piston retreats into the liner by means of mobile stop (11) that can be moved forward by the piston as a braking force is applied. An elastic return member (16) returns the piston towards the position of retreat bearing against the mobile stop. The wear compensation device extends between the liner and the piston, downstream of a seal extending between the liner and the piston so as not to be bathed in the fluid in the cavity, the stop being held still by friction on the liner.
