Abstract
An actuator includes a screw mechanism () having a threaded nut () rotatable by an electric motor () about a longitudinal axis (x) and a screw () translatable along the axis between an axially extended position and an axially retracted position. The screw () is connectable to a wire (W) of a Bowden cable (C) having an outer sheath (S). The actuator has a casing () with a first, fixed transversal surface (). A cup () is mounted axially slidably on the casing () and has a second transversal surface () adapted for resting against an end of the sheath (S). A spring () is compressed between the first, fixed transversal surface () and the sliding cup (). The cup () is capable of reaching an axially extended position, corresponding to a released brake condition, and an axially retracted position towards the first fixed transversal surface (), against the bias of the spring (), corresponding to a brake actuated condition.
