Abstract

The friction member (4a) is actuated, via a piston mechanism (5), by an assembly consisting of a wedge (12) and of rollers (14), put into operation as a result of the rotation of a control shaft (11) driven by an electric motor (8) under the supervision of a force or pressure sensor (23) associated with one of the surfaces of ramps (16) interacting with the rollers (14).
