Abstract

Viene descritto un dispositivo di controllo della pressione frenante con una valvola del freno di esercizio per la guida della pressione da una sorgente di riserva e tramite un regolatore di forza frenante (regolatore ALB) automaticamente - dipendente dal carico - ai cilindretti dei freni delle ruote di un assale posteriore e da una sorgente di riserva ai cilindretti dei freni delle ruote di un assale anteriore di un autoveicolo che, inoltre, presenta sensori di usura per il rilevamento dei rispettivi spessori residui delle guarnizioni dei freni, dove i segnali di uscita dei sensori di usura vengono inviati ad un sistema elettronico di comando che, in presenza di usura differente delle guarnizioni di entrambi gli assali, genera un segnale per l'attivazione di una valvola elettromagnetica, mediante la quale la pressione frenante dei freni delle ruote di un assale può essere corretta. Invece di eseguire una correzione della pressione frenante di volta in volta sui freni delle ruote dell'assale, che rispetto ai freni delle ruote dell'altro assale presentano una usura più forte, secondo l'invenzione una correzione della pressione frenante ha luogo sempre soltanto sui freni delle ruote di un assale (VA oppure HA), dove solo a questo assale è associata una valvola elettromagnetica.
