Abstract

Patente de Invenção: <B>"PROJETO DE CUNHA DE ATRITO OTIMIZADO PARA ALTO MOMENTO DE ATRITO DE EMPENO E BAIXA FORçA DE AMORTECIMENTO"<D>. Um sistema de amortecimento para um vagão ferroviário utiliza cunhas de atrito suportadas em molas longitudinais, para amortecer o movimento relativo entre a travessa do vagão ferroviário e as estruturas laterais que a suportam. Cada cunha de atrito tem uma forma geralmente triangular com um ângulo <sym> definido entre uma superfície de atrito vertical, que se apóia em uma estrutura lateral, e uma superfície de atrito de inclinação, que se movimenta em relação à travessa. O ângulo <sym> e a força P de cada mola longitudinal são definidos por:
