Abstract

L'invenzione concerne un impianto idraulico di frenatura per un veicolo stradale con trazione sull'assale posteriore e distribuzione del circuito frenante sull'assale anteriore e sull'assale posteriore, il quale è equipaggiato con un sistema antibloccaggio (ABS), con un dispositivo di regolazione dello slittamento nella trasmissione (ASR) e con un comando di distribuzione elettronico di forza frenante (EBKV). Per la realizzazione di queste funzioni di regolazione e di comando sull'assale posteriore del veicolo è previsto un modulatore di pressione avente una camera di modulazione collegata tramite valvole regolatrici della pressione frenante con i freni delle ruote posteriori, la quale è delimitata da un pistone del modulatore verso una camera di pressione di comando, in cui è imprigionata, mediante comando di valvole, la pressione di uscita di una sorgente di pressione ausiliaria. Il pistone del modulatore è spinto, mediante una molla di richiamo, nella posizione corrispondente al massimo volume della camera di modulazione, la quale è, sia per una frenatura normale sia per il lavoro di ASR, la posizione di uscita. Il modulatore di pressione è dimensionato in modo tale da
