Abstract

A rail vehicle (100) has a brake system containing a brake actuator (120) and a brake unit (200). The brake actuator (120) receives a brake command (cmdp) and produces a resulting electric brake-force signal (BF). The brake unit (200) contains first and second pressing members (211) and a rotatable member (110) being mechanically linked to at least one wheel (105) of the rail vehicle (100). When receiving the electric brake-force signal (BF), the brake unit (200) causes the first and second pressing members (211) to apply a braking force to the rotatable member (110). A gear assembly (220) in the brake unit (200) operates mechanically on the first and second pressing members (211). A stepper motor (230), in turn, acts on the gear assembly (120) in response to the electric brake-force signal (BF), thus causing the first and second pressing members (211) to move towards or away from the rotatable member (110) and attain a specified position interrelationship. Based on a position signal (P) indicating an angular position of the stepper motor's (230) power transmission shaft, the brake unit (200) determines if the specified position interrelationship has been attained; and if so, it stops producing the electric brake-force signal (BF) to allow a self-locking mechanism to lock the first and second pressing members (211).
