Abstract
The invention relates to a device for braking/driving an aircraft wheel mounted to rotate on an undercarriage axle, the device comprising: a stack of disks comprising disks that are constrained in rotation with the wheel and that alternate with disks that are constrained in rotation with a torsion tube; a support member mounted to rotate on the axle and constrained in rotation with the torsion tube; braking actuators carried by the support member for selectively pressing the disks together; and a drive member for selectively driving the support member in rotation; the support member carrying a secondary of a transformer having a primary arranged facing the support member while being stationary in rotation, the secondary being electrically connected to the actuators and the primary being adapted to being connected to a non-DC voltage source.
