Abstract

a. L'invention concerne un circuit de régulation électropneumatique pour la force de freinage de véhicules. b. Une tension d'un pont de Wheatstone 8, 9, 10 et 11, 12, 13 représentant un écart de réglage est appliquée aux entrées d'un amplificateur différentiel qui est relié à deux comparateurs 15, 16 représentant des détecteurs de signes, ces comparateurs étant reliés, par l'intermédiaire d'amplificateurs 17, 18 à des bobines d'excitation 19, 20 d'électrovannes d'alimentation et de désaération des cylindres de frein. c. Application aux dispositifs de freinage de véhicules sur rails.at. The invention relates to an electro-pneumatic control circuit for the braking force of vehicles. b. A voltage from a Wheatstone bridge 8, 9, 10 and 11, 12, 13 representing a control deviation is applied to the inputs of a differential amplifier which is connected to two comparators 15, 16 representing sign detectors, these comparators being connected, by means of amplifiers 17, 18 to excitation coils 19, 20 of supply and deaeration solenoid valves of the brake cylinders. vs. Application to the braking devices of rail vehicles.
