Abstract

Gépjármű-fékrendszer, mely magában foglal egy elsődlegesfolyadékszivattyút (10); egy változtatható szállításúfolyadékszivattyút (36), jobb- és baloldali üzemi féket (12, 14),valamint jobb- és baloldali másodlagos féket (30, 32). Egy üzemifékszelep (16) csatlakozik a rendszerhez az elsődlegesfolyadékszivattyú (10) és az üzemi fék között, és működteti az üzemifékeket (12, 14) az üzemi fékpedálok (18, 20) függvényében. Jobb- ésbaloldali üzemi fékkapcsolók (44, 46) jelet generálnak az üzemifékpedálok (18, 20) helyzetének függvényében. Egy elektrohidraulikusmásodlagos fékszabályozó szelep működteti a másodlagos féket (32) egyelektromos jel függvényében. Féknyomás-érzékelők szolgáltatnakféknyomásjeleket az üzemi féknyomás, valamint a másodlagos féknyomásfüggvényében. Egy elektronikus szabályozó kapcsolódik az üzemifékkapcsolókhoz (44, 46), a féknyomás-érzékelőkhöz (42, 48) és amásodlagos fékszabályozó szelephez. Az elektronikus szabályozóegységjelet generál az üzemi fékek (12, 14) helyzetének és aféknyomásjeleknek a függvényében. Ó
