Abstract
(DE)
Ein Pneumatik-Kombi-Pneumatikzylinder (1) und ein entsprechendes Steuerungsverfahren zeichnen sich dadurch aus, dass direkt in dem einen von zwei Druckräu­men (8, 9), und zwar dem Druckraum (9), der zur Durchführung von Betriebs­bremsungen mittels Druckerhöhung ausgelegt ist, auch eine Feder (19) zur Reali­sierung der Feststellbremsfunktion angeordnet ist, so dass mit nur zwei Druckräu­men (8, 9) und der Feder (19) sowohl die Betriebsbrems- als auch die Feststell­bremsfunktion realisierbar sind.
(EN)
A combined pneumatic cylinder (1) and a corresponding control method are characterized in that a spring (19) for realizing the parking brake function is directly placed inside one of two pressure chambers (8, 9) and, to be precise, inside the pressure chamber (9) that is designed for effecting service brakings by increasing pressure. The service brake function as well as the parking brake function can be realized by means of only two pressure chambers (8, 9) and the spring (19).
(FR)
L'invention concerne un cylindre pneumatique combiné (1) et un procédé de commande correspondant, caractérisés en ce qu'un ressort (19), en vue de réaliser la fonction de frein de stationnement, est disposé directement à l'intérieur de l'une des deux chambres de pression (8, 9), à savoir, la chambre de pression (9) qui est prévue pour effectuer le freinage de service par augmentation de pression, de telle sorte qu'en ayant recours uniquement à deux chambres de pression (8, 9) et au ressort (19), on puisse réaliser aussi bien la fonction frein de service que la fonction frein de stationnement.
