Abstract
MECANISMO DE FRENADO MECANICO COMPUESTO POR UN SERVOMECANISMO DE FRENADO POR AIRE COMPRIMIDO (1) ASOCIADO CON UN CILINDRO PRINCIPAL (2). EL SERVOMECANISMO COMPRENDE UN PISTON DE AIRE COMPRIMIDO MOVIL (5) QUE TIENE UNA VALVULA (7), Y FUNCIONA SEGUN EL PRINCIPIO DE REACCION HIDRAULICA, AL TENER EL CILINDRO HIDRAULICO (11) DEL CILINDRO PRINCIPAL, UN CILINDRO HUECO MOVIL (13), QUE RECIBE UNA FUERZA DE ENTRADA. LA REACCION HIDRAULICA GENERADA POR LA FUERZA DE SOBREALIMENTACION ES RETARDADA POR MEDIO DE UNA VALVULA DE RETENCION (22) SITUADA ENTRE EL CILINDRO PRINCIPAL (2) Y EL CILINDRO MOVIL (13).
