Abstract

SERVOMOTOR, PARA AYUDA EN LA FRENADA DE VEHICULOS. EL MECANISMO DE ACCIONAMIENTO DE ESTE SERVOMOTOR PERMITE OBTENER UNA REDUCCION DE LA CARRERA EN VACIO SIN REDUCIR EL LEVANTAMIENTO DE LA VALVULA AL SOLTARSE EL FRENO. UN TOPE MOVIL (60) SE EXTIENDE APROXIMADAMENTE PERPENDICULAR AL EJE DE LA BARRA DE EMPUJE (36), MANTENIDO POR UN ELEMENTO RESILIENTE (39) CONTRA UN SOPORTE QUE ESTA FIJO CON RELACION AL PISTON DE ACCIONAMIENTO (20), EN LA POSICION DE REPOSO. DICHO TOPE COOPERA CON UN RESALTO (61) DE LA BARRA DE ACCIONAMIENTO PARA MANTENER EL VASTAGO MOVIL DE LA BARRA A CORTA DISTANCIA DEL ASIENTO ANULAR, REDUCIENDO POR LO TANTO LA CARRERA EN VACIO DE ACCIONAMIENTO DEL SERVOMOTOR.
