Abstract

"SERVOFREIO". A invenção refere-se a um servo freio com um elemento de entrada (20) para acionar o servo freio. O dito elemento de entrada (20), em sua extremidade voltada para o pedal de freio, compreende uma manga (20A) para receber uma haste de acionamento (34) a ser acoplada ao pedal de freio. Dentro da dita manga (20A) um cilindro flexivel (36) com pelo menos um elemento de mola (36C, 36D) é disposto, e interage com a haste de acionamento (34) quando a última é colocada em uma posição travada com relação ao elemento de entrada (20). O elemento de mola (36C, 36D) se estende substancialmente na direção axial e pode ser elasticamente acionado radialmente para fora. O cilindro flexível (36), na extremidade do pedal de freio, possui um corte (36F) que se estende radialmente para fora e que é fixado à manga (20A) por meio de uma seção de flange (20D) da manga (20A).
