Abstract
A braking device including a housing mounted in relative rotation relative to a shaft, braking discs, a braking piston adapted to stress the braking discs, a spring washer mounted on the brake housing on a support zone located on one of the peripheries of its first face, and having on its second face a braking support zone, which cooperate with the braking piston so as to stress the braking discs according to a braking direction. An unbraking piston is adapted to stress the washer according to a direction opposite said braking direction. The spring washer has an unbraking support zone with the unbraking piston on the other of the peripheries of the second face of the spring washer. The braking support zone is located at an intermediate position of the at least one spring washer.
