Abstract
A rail vehicle (100) has a brake system with a brake unit (200) configured to receive a brake command (cmdB) and response thereto execute a brake action. The brake unit (200) contains a rotatable member (110) and first and second pressing members (211). The rotatable member (110) is mechanically linked to at least one wheel (105) of the rail vehicle (100). The first and second pressing members (211) are configured to move relative to the rotatable member (110) to execute the brake action. The brake unit (200) also contains a brake actuator (120) configured to produce an electric brake-force signal (BF) in response to the brake command (cmdB), a gear assembly arranged to operate mechanically on the first and second pressing members (211) and an electric motor (230) configured to act on the gear assembly (220) in response to the electric brake-force signal (BF). The brake actuator (120), in turn, includes a processing unit (125) that is configured to produce the electric brake-force signal (BF) based on the brake command (cmdB). Thus, the electric brake-force signal (BF) is efficiently protected from interfering electromagnetic radiation.
