Abstract
The invention relates to a device for braking and driving rotation of a wheel (1) mounted to rotate on an aircraft landing gear axle, the device comprising: a torsion tube (26) adapted to be mounted to rotate on the axle that carries the wheel; a stack of disks (30) including first disks having means for constraining them in rotation with the wheel and second disks arranged in alternation with the first disks and including means for constraining them in rotation with the torsion tube; a ring (23) carrying braking actuators (24) that are adapted to act selectively to press the disks against one another, the ring being constrained in rotation with the torsion tube in order to form a rotary portion (20) of the device; a rotary drive member (40) for driving rotation of the rotary portion (20); and finally blocking means (51, 52) for selectively blocking rotation of the rotary portion, which means are independent of the rotary drive member.
