Abstract

Una pinza per sistemi di frenatura a disco a comando elettroidraulico, particolarmente per veicoli tramviari metropolitani, comprende un corpo (1) recante una coppia di pattini di frenatura (8, 9) che cooperano con un disco girevole (2). Il corpo (1) è montato flottante in direzione parallela all'asse del disco (2). Uno dei due pattini di frenatura (9) è mobile sotto l'azione di mezzi di comando che comprendono un equipaggio mobile (13) al quale sono associati un dispositivo idraulico di frenatura diretta (18) ed un dispositivo di frenatura inversa (21, 25) di stazionamento, dei quali il primo interviene in presenza di pressione di fluido ed il secondo interviene in assenza di pressione di fluido. Al dispositivo di frenatura inversa (21, 25) è associato un organo di disinserimento (35) azionabile dall'esterno del corpo (1).(Figura 2)A caliper for electro-hydraulic controlled disc braking systems, particularly for metropolitan tram vehicles, includes a body (1) bearing a pair of brake pads (8, 9) which cooperate with a rotating disc (2). The body (1) is mounted floating in a direction parallel to the axis of the disc (2). One of the two braking pads (9) is movable under the action of control means which comprise a mobile crew (13) with which a direct braking hydraulic device (18) and a reverse braking device (21, 25) are associated. ) of parking, of which the first intervenes in the presence of fluid pressure and the second intervenes in the absence of fluid pressure. The reverse braking device (21, 25) is associated with a release device (35) which can be activated from outside the body (1). (Figure 2)
