Abstract

"SAPATA DE FREIO DE CONTROLE DE FRICçãO". A presenteinvenção fornece uma sapata de freio para controle de fricçãoadaptada para engatar a face de rolamento e o flange de uma rodade um veículo ferroviário através da qual o veículo ferroviário ésustentado de forma guiável em uma linha com trilhos. A sapata defreio para controle de fricção compreende uma placa de apoio comum elemento de flange. Há uma lona de freio afixada à placa deapoio e que tem uma superfície de frenagem engatável com a facede rolamento da roda de um veículo ferroviário. A lona de freioinclui um primeiro material de composição de fricção formado compelo menos um dentre um modificador de fricção positiva elevadasólido e um modificador de fricção positiva muito elevada sólidoque estabelece um nível de fricção necessário entre a face derolamento de roda e a linha com trilhos para parar um trem. Asapata de freio também tem uma parte de flange afixada aoelemento de flange da placa de apoio, sendo que a referida partede flange tem uma superfície de fricção engatável com o flange deroda de uma roda de vagão ferroviário. A parte de flange inclui umsegundo material de fricção formado com um modificador sólidocom baixo coeficiente de fricção que estabelece um nível defricção entre aproximadamente 0,08 e 0,15 em uma interface entreo flange de roda e a linha com trilhos.
