Abstract

"EQUIPAMENTO SERVOMOTOR PNEUMáTICO DE AUXìLIO à FRENAGEM, DISPOSITIVO DE MONTAGEM PARA FIXAçãO DE UM DIAFRAGMA A UMA SAIA DE UM EQUIPAMENTO SERVOMOTOR, E PROCEDIMENTO DE MONTAGEM DE UM DIAFRAGMA SOBRE UMA SAIA DE UM EQUIPAMENTO SERVOMOTOR". A presente patente trata de um equipamento servomotor (12) pneumático de auxilio à frenagem para um veiculo automotivo, do tipo que comporta um envelope (16) rígido basicamente cilíndrico no interior do qual se movimenta uma divisória (18) transversal comportando uma saia (28) periférica em chapa metálica, recoberta, pelo menos na proximidade da sua periferia (40) por um diafragma (30 ) de estanqueidade em material elastomero, cuja periferia (32) é fixada no envelope (16) de maneira estanque, caracterizada pelo fato de que a saia (28) comporta, na proximidade da sua periferia (40) uma tala (42) anular embutida delimitando uma ranhura (44) interna que se destina a receber, sem jogo, um bloco (46) periférico que faz projetar a superfície do diafragma (30) para assegurar a fixação estanque do referido diafragma (30) sobre a saia (28).
