Abstract

An electrically operated brake assembly (200) for a rail vehicle contains: a rotating member mechanically linked to a wheel axle of the rail vehicle, at least one friction member (221; 222) movable between an engaged position in which the at least one friction member (221; 222) contacts the rotating member, and a disengaged position in which the rotating member is freely rotatable without contacting the at least one friction member (221; 222), a gear assembly (220) arranged to operate mechanically on the at least one friction member (221; 222), an electric motor (230) controllable via a control signal (CS) and configured to cause the gear assembly (220) to operate on the at least one friction member 221; 222) to move between the engaged and disengaged positions, a force sensor (225) configured to produce a pressure signal (F) indicating a magnitude of a force at which the at least one friction member (221; 222) contacts the rotating member, an angular position sensor (237) configured to produce a pulse-count signal (PC) where each pulse count reflects a particular angular movement of an output shaft of the electric motor (230) and a controller (120) configured to obtain the pressure signal (F) and the pulse count signal (PC), and based thereon define a home position for the electric motor (230).
