Abstract

ESTE DISPOSITIVO DE FRENADA ASISTIDA COMPRENDE UN SERVOMOTOR NEUMATICO DE FRENADA (1) ASOCIADO A UN CILINDRO PRINCIPAL (2). EL SERVOMOTOR COMPRENDE UN PISTON NEUMATICO MOVIL (5) QUE LLEVA UNA VALVULA (7) Y FUNCIONA SEGUN UN PRINCIPIO DE REACCION HIDRAULICA, COMPRENDIENDO EL PISTON HIDRAULICO (11) DEL CILINDRO PRINCIPAL DE HECHO UN CILINDRO MOVIL HUECO (13) QUE RECIBE UNA FUERZA DE ASISTENCIA, Y UN PISTON HIDRAULICO QUE RECIBE UNA FUERZA DE ENTRADA, CONSTITUYENDO ESTAS DOS FUERZAS LA FUERZA DE ACCIONAMIENTO TOTAL. UN MUELLE HELICOIDAL (22) QUE EJERCE UNA FUERZA ELASTICA AJUSTABLE, ESTA DISPUESTO ENTRE EL PISTON HIDRAULICO SECUNDARIO Y EL CILINDRO MOVIL PARA PERMITIR EL AJUSTE DEL VALOR MINIMO NO NULO DE LA FUERZA DE ACCIONAMIENTO.
