Abstract

A UNA PLACA DE ANCLAJE (10) VAN FIJADOS, DIAMETRALMENTE OPUESTOS, UN CILINDRO DE FRENO DE RUEDA HIDRAULICO (12) Y LA CAJA (22) DE UN SOPORTE INTERMEDIO (20) QUE LLEVA SUJETAS POR SUS EXTREMOS OPUESTOS AL CILINDRO DE FRENO DE RUEDA (12), DOS MORDAZAS DE FRENO (16,18). CERCA DEL CILINDRO DE FRENO DE RUEDA (12) SE ENCUENTRA, ADICIONALMENTE, UN DISPOSITIVO DE MANIOBRA MECANICO (50-58). EL CILINDRO DE FRENO DE RUEDA (12) Y EL SOPORTE INTERMEDIO (20) ESTAN COLOCADOS DE TAL MANERA, QUE AL ACTIVARSE EL FRENO HIDRAULICAMENTE Y EN AVANCE DEL VEHICULO, AMBAS MORDAZAS (16,18) SEAN MORDAZAS DE DESCENSO. LA CAJA (22) DEL SOPORTE INTERMEDIO (20) ESTA PROVISTA DE UNA GUIA (24) MAS O MENOS PARALELA AL CILINDRO DE FRENO DE RUEDA (12), Y DE UN TOPE (26). EN LA GUIA (24) HAY UN ELEMENTO DE REAJUSTE (28) QUE PUEDE DESPLAZARSE AXIALMENTE DENTRO DE UN MARGEN DETERMINADO. UNA DE LAS MORDAZAS DE FRENO (16) SE APOYA EN UN EXTREMO DE UN TAQUE (34) QUE AL ACTIVARSE EL FRENO HIDRAULICAMENTE, MEDIANTE UNA FUERZA (C) QUEACTUA SOBRE SU OTRO EXTREMO, PUEDE DESPLAZARSE HACIA ESTA MORDAZA (16). A ESTA FUERZA (C) EL TAQUE (34) ESTA COMPLETAMENTE SOMETIDO, MIENTRAS QUE AL DESPLAZAMIENTO EN LA OTRA DIRECCION POR EL ELEMENTO DE REAJUSTE (28), OPONE UNA FUERZA DE AUTORRETENCION. EL FRENO TIENE EN FUNCIONAMIENTO HIDRAULICO UNA CARACTERISTICA REGRESIVA, Y EN FUNCIONAMIENTO MECANICO UNA CARACTERISTICA PROGRESIVA.
