Abstract

L'invention concerne un système de freinage (1) comprenant : - un frein dynamique (10), comprenant un vérin hydraulique (11), comprenant un cylindre (12), un piston (13) mobile dans le cylindre (12), et une chambre (14) apte à être remplie pour déplacer le piston dans le cylindre et actionner le frein, - un circuit (20) d'alimentation du frein, comprenant un réservoir (21), une pompe (22), et une ligne d'alimentation (26) du frein, un dispositif de commande du frein (30), comprenant une valve de régulation de pression de fluide (32) dans la chambre du frein, et une commande progressive (31), la valve comprenant une voie reliée à la ligne d'alimentation, une voie reliée au réservoir, et une voie reliée à la chambre du frein, et étant adaptée pour sélectivement relier la voie reliée à la chambre à l'une ou l'autre des autres voies, pour délivrer une pression déterminée dans la chambre en fonction d'un degré d'actionnement de la commande, le système de freinage étant caractérisé en ce qu'il comprend en outre une ligne de refroidissement (40) de la chambre, adaptée pour renouveler le fluide contenu dans la chambre pour assurer le refroidissement de ladite chambre.
