ELECTROMECHANICAL BRAKE ACTUATOR FOR ELECTROMECHANICAL BRAKE ARRANGEMENT

An electromechanical brake actuator () is configured to move a service-brake rod () between a full-braking position (BP) and a drive position (DP). A parking-brake rod () is coupled to the service-brake rod and is movable between a first position (P) for locking the service-brake rod () in the full-braking position (BP), and a second position (P) where the service-brake rod () is free to be moved. A spring element () coupled to the parking-brake rod is arranged so that in a fully-compressed state (CS) the parking-brake rod is in the second position, and in a fully-released state (RS) the parking-brake rod is in the first position. A hydraulic unit () is operatively coupled to the parking-brake rod and configured, based on a parking-brake signal, to lock the parking-brake rod or allow a release of the spring element to the fully-released state.
