Abstract

Viene descritto un procedimento per la regolazione dell'usura della guarnizione del freno nel senso di una compensazione di differenze di usura della guarnizione del freno in un impianto di frenatura di autoveicolo azionato con mezzo a pressione con una valvola di freno di servizio e con valvole elettromagnetiche collocate a valle, con un sensore di usura per il rilevamento dell'usura di ciascuna guarnizione del freno di ciascuna ruota, dove i segnali di uscita dei sensori di usura vengono inviati ad una elettronica di controllo che, in presenza di diversa usura delle guarnizioni dei freni, genera segnali per l'attivazione delle valvole elettromagnetiche mediante i quali vengono comandate le pressioni frenanti dei freni sulle ruote, in cui si determina un ulteriore valore dell'usura della guarnizione del freno indirettamente dalle grandezze fisiche di stato della ruota captata e non captata dello stesso assale durante una frenatura e a base della regolazione si pone, come valore reale di usura della guarnizione del freno, il valore maggiore dei due valori di usura del freno direttamente rilevato e indirettamente determinato.A method is described for adjusting the wear of the brake lining in the sense of compensating for differences in wear on the brake lining in a motor vehicle braking system operated by means of pressure with a service brake valve and electromagnetic valves. located downstream, with a wear sensor for detecting the wear of each brake lining of each wheel, where the output signals of the wear sensors are sent to a control electronics which, in the presence of different wear of the gaskets of the brakes, generates signals for the activation of the electromagnetic valves through which the braking pressures of the brakes on the wheels are controlled, in which a further wear value of the brake gasket is determined indirectly by the physical quantities of the state of the wheel captured and not captured of the same axle during braking and based on the adjustment it is set as a real value wear of the brake lining, the higher of the two brake wear values directly detected and indirectly determined.
