Abstract

EN UN APARATO DE FRENO (10) CON REFORZADOR DE LA POTENCIA DE FRENO (26) HIDRAULICO INTEGRADO PARA UN VEHICULO DE CARRETERA CON INSTALACION DE FRENO HIDRAULICO DE DOS CIRCUITOS CON UN CIRCUITO DE FRENO ESTATICO DEL EJE DELANTERO (1) Y UN CIRCUITO DE FRENO ESTATICO DEL EJE TRASERO (II) QUE SE ENCIERRA EN UN ESPACIO DE PRESION DE SALIDA PRIMARIO (23) O SECUNDARIO (24), COMPRENDE EL ESPACIO DE PRESION DE SALIDA PRIMARIO (23) UN PRIMER ESPACIO PARCIAL (23'') MOVIL UNILATERALMENTE POR UN ELEMENTO DE EMBOLO (18) DEL DISPOSITIVO ASI COMO UN SEGUNDO ESPACIO PARCIAL (23") EN CONEXION COMUNICANDOSE CON EL PRIMER ESPACIO PARCIAL, QUE SE LIMITA MOVIENDOSE AXIALMENTE EN EL INTERIOR DE UN SEGUNDO ORIFICIO DEL DEPOSITO (38) HACIA UN ELEMENTO DE EMBOLO DESLIZABLE POR EL EMBOLO SECUNDARIO (22) Y HACIA OTRO QUE PRESIONA UNO CONTRA OTRO, DE LOS QUE UNO ESTA FORMADO COMO EMBOLO ANULAR (19) Y EL SEGUNDO COMO EMBOLO SUMERGIBLE (21). ESTA PREVISTO UN PRIMER ELEMENTO DE TRANSMISION DE FUERZA AXIAL (30) EN FORMA DEYUGO QUE PROPORCIONA UN ACOPLAMIENTO DE MOVIMIENTO DEL EMBOLO PRIMARIO (18) QUE LIMITA EN EL PRIMER ESPACIO PARCIAL (23'') CON SOLAMENTE UNO DE AMBOS ELEMENTOS DE EMBOLO QUE LIMITAN EL SEGUNDO ESPACIO PARCIAL (23"). ADEMAS ESTA PREVISTO UN SEGUNDO ELEMENTO DE TRANSMISION DE FUERZA AXIAL (29) QUE PROPORCIONA UN ACOPLAMIENTO DE MOVIMIENTO DEL OTRO ELEMENTO DE EMBOLO (19) CON EL EMBOLO IMPULSOR (53) ASI COMO UN TERCER ELEMENTO DE TRANSMISION DE FUERZA AXIAL (28) SOBRE EL QUE EN CASO DE PERDIDA DEL REFORZADOR DE FUERZA DE FRENO ACTUA LA FUERZA DEL PEDAL EN EL ELEMENTO DE TRANSMISION DE FUERZA AXIAL EN FORMA DE YUGO.
