Abstract

Dispositif de freinage pneumatique ayant une chambre de frein, un piston se déplaçant dans un sens et dans l'autre dans cette chambre de frein, une tige de poussée reliée au piston et des moyens d'actionnnement du frein fonctionnellement associés à la tige de poussée. Il comprend des moyens pour indiquer lorsque la course de la tige de poussée excède une longueur prédéterminée, ces moyens comprenant un circuit électrique avec un signal avertisseur lumineux ou acoustique, un interrupteur muni de moyens d'actionnement pour actionner le signal avertisseur qui sont actionnés par coopération avec une structure se déplaçant avec la tige de poussée, les moyens d'actionnement étant positionnés à un endroit prédéterminé de façon à être attaqués et actionnés par cette structure lorsque la tige de poussée s'est déplacée de cette longueur prédéterminée.Pneumatic braking device having a brake chamber, a piston moving in one direction and the other in this brake chamber, a push rod connected to the piston and brake actuation means operatively associated with the push rod . It comprises means for indicating when the stroke of the push rod exceeds a predetermined length, these means comprising an electrical circuit with a light or acoustic warning signal, a switch provided with actuating means for actuating the warning signal which are actuated by cooperation with a structure moving with the push rod, the actuating means being positioned at a predetermined location so as to be attacked and actuated by this structure when the push rod has moved by this predetermined length.
