Abstract

A rail vehicle brake system includes a brake unit (200) that receives an electric brake-force signal (BF) designating a set force value (F_set). The brake unit (200) contains: pressing members (211, 212), a rotatable member mechanically linked a wheel of the rail vehicle, a gear assembly (220) that operates mechanically on the pressing members (211; 212) so as to move them towards or away from the rotatable member, an electric motor (230) that, in response to the electric brake-force signal (BF), acts on the gear assembly (220) to cause the gear assembly (220) to operate the pressing members (211; 212), a load-cell sensor (250) produces a sensor signal (F) representing the force applied by the pressing members (211, 212), and a locking mechanism that locks the pressing members (211; 212). The brake actuator (120) obtains the sensor signal (F). When the magnitude of the applied force matches the set force value (F_set), the brake actuator (120) controls the locking mechanism to lock the pressing members (211; 212). The locking mechanism is self-locking, included in and forms an integral part of the gear assembly (220).
