Abstract
The invention relates to a braking system for a rail vehicle, the braking system having at least one braking assembly mounted on an axle of the vehicle, and a friction disk and pads, at least the friction disk being made of a composite material based on carbon, the friction disk being keyed to the axle, the pads being disposed on stators housed in elements flanking the disk. The flanking elements are supported by the vehicle or a bogie corresponding to the axle, and the stators for the pads are actuated by actuators, the flanking elements being supported by the vehicle or by the bogie via a hinge member allowing for track distortion and play. A return member connects the elements to the vehicle or to the bogie.
