Abstract

"SERVOMOTOR PARA FREAGEM DE EMERGêNCIA". Que provê auxílio à freagem para um veículo a motor, do tipo que comporta um dispositivo (56) de embreagem unidirecional, e que comporta uma bucha (58) coaxial, deslizante sobre um êmbolo (46), e uma chave (60) sensivelmente anular que envolve com folga a bucha (58) e que é susceptível, quando um esforço de entrada for aplicado a uma velocidade determinada sobre uma haste de comando (38), solidária do êmbolo (46), de ser arrastada por um pistão (22) móvel para bascular e bloquear a bucha (58) numa posição axial na qual ela bloqueia pistão (22) independentemente da haste de comando (38), caracterizado pelo fato de que a embreagem (56) unidirecional, comporta pelo menos uma face transversal (76) de bloqueio da bucha que é virada axialmente para trás para formar um encosto para uma unha (78) da chave (60) estendendo-se radialmente para a bucha (58), de maneira a indexar axialmente a posição de bloqueio extremo da bucha (58).
