Abstract

"SERVOMOTOR PNEUMáTICO DE AUXìLIO DE FRENAGEM, COM PROGRAMA DE FRENAGEM PARA FRENAGEM BRUSCA". Para evitar que durante uma frenagem brusca um relaxamento do pedal do freio por um motorista, leve este último a uma percussão, prevê-se que um relaxamento brusco que sucede a um pisar brusco sobre o pedal de freio, seja seguido por uma manutenção automática da frenagem, durante um certo tempo. Este resultado é obtido montando um equipamento móvel de um servomotor pneumático de auxílio de frenagem, um circuito com histérese mecânica. Um deslocamento das peças de transmissão dos esforços neste circuito é diferente conforme o esforço for normal ou brusco. Se for brusco, um êmbolo comportando um distribuidor (18) e um apalpador (15) é empurrado contra um disco de reação (29). Se a este esforço brusco sucede uma retração brusca, o apalpador permanece em ação por intermédio de uma catraca (32, 33, 34) enquanto o distribuidor recua.
