Simple SummaryContent extracted with AI.

This invention describes a method and system for determining key braking characteristics, such as braking force and brake setting, in a railway freight wagon. It uses a rotation sensor (e.g., an incremental encoder with a Hall sensor) attached to a rotating component of the brake rigging adjuster to measure its movement when the brakes are released after a braking event. The measurement data is then wirelessly transmitted to an evaluation unit, which calculates and characterizes the preceding braking operation. The invention also includes a railway freight wagon and an arrangement that implements this method.

Use CasesContent extracted with AI.

  • Automated brake system testing and monitoring in railway freight wagons
  • Condition monitoring and predictive maintenance for freight train brake systems
  • Integration with train control systems for safer and more efficient rail operations
  • Data-driven maintenance scheduling based on actual use and wear
  • Improvement of brake performance diagnostics without manual inspection

BenefitsContent extracted with AI.

  • Enables digital, automated, and remote evaluation of brake performance in non-electrified freight wagons
  • Increases operational safety by continuously monitoring brake status
  • Reduces the need for manual brake tests, saving labor and time
  • Improves reliability and efficiency of railway freight transport
  • Supports predictive maintenance, reducing unplanned downtime and optimizing maintenance intervals
  • Contactless measurement minimizes mechanical wear and susceptibility to vibration or shock

Patent Abstract

Die Erfindung betrifft ein Verfahren zum Bestimmen einer Bremskenngröße für einen Bremsvorgang eines Schienengüterwagens mit: Bereitstellen einer Drehmesseinrichtung (10), die eingerichtet ist, Messwerte für eine oder mehrere Kenngrößen einer Drehbewegung zu erfassen; Erfassen eines Messwertes für eine Kenngröße einer Drehbewegung eines drehbar gelagerten Bauteils (6) eines Bremsgestängestellers (5) eines Bremssystems eines Schienengüterwagens, welche das drehbar gelagerte Bauteil beim Lösen des Bremssystems nach einem vorangehenden Bremsvorgang ausführt; Bereitstellen des Messwertes für die Kenngröße in einer Auswerteeinrichtung und Bestimmen einer Bremskenngröße, welche den vorangehenden Bremsvorgang charakterisiert, mittels der Auswerteeinrichtung auf Basis des Messwertes für die Kenngröße. Weiterhin sind ein Schienengüterwagen und eine Anordnung geschaffen, die eingerichtet ist, das Verfahren auszuführen.
