Abstract

PARA CIRCULAÇÃO EM REDES FERROVIÁRIAS DE BITOLA IBÉRICA OU EUROPEIA, REUTILIZANDO BOGIES TIPO Y25 DE BITOLA IBÉRICA. O RODADO TEM DUAS RODAS DE BITOLA VARIÁVEL E UM EIXO COMUM [5], SENDO CADA RODA CONSTITUÍDA PELA RODA-BASE [2] E A RODA DE CONTACTO [1] COM MOVIMENTO DE TRANSLAÇÃO. CADA RODA TEM OITO GRUPOS BLOQUEADORES E DUAS FLANGES POSTIÇAS [6] E [7] APARAFUSADAS EM AMBOS OS LADOS DA RODA-BASE [2] NA ESTAÇÃO DE MUDANÇA DE BITOLA, O ANEL DE COMANDO [15] PRESSIONA AS MOLAS HELICOIDAIS DE COMPRESSÃO [12] E EMPURRA AS CUNHAS DE APERTO [4] PARA TRÁS, PERMITINDO AOS BLOQUEADORES CENTRÍFUGOS PRINCIPAIS [3] RECOLHEREM, PARA A RODA DE CONTACTO [1] MUDAR DE BITOLA. OS BLOQUEADORES CENTRÍFUGOS PRINCIPAIS [3] MANTÊM A RODA DE CONTACTO [1] FORTEMENTE PRESSIONADA DE ENCONTRO ÀS FLANGES POSTIÇAS [6] OU [7] DA RODA-BASE [2], CONSOANTE A BITOLA EM USO, DE MODO A OBTER UMA RIGIDEZ SEMELHANTE À DE UM RODADO MONOBLOCO.FOR CIRCULATION ON IBERIAN OR EUROPEAN GAUGE RAILWAY NETWORKS, REUSING IBERIAN GAUGE TYPE Y25 BOGIES. THE WHEEL HAS TWO WHEELS OF VARIABLE GAUGE AND A COMMON AXLE [5], WHICH EACH WHEEL CONSTITUTES THE BASE WHEEL [2] AND THE CONTACT WHEEL [1] WITH TRANSLATION MOVEMENT. EACH WHEEL HAS EIGHT LOCKING GROUPS AND TWO FLUSH FLANGES [6] AND [7] SCREWED ON BOTH SIDES OF THE BASE WHEEL [2] AT THE GAME CHANGE STATION, THE CONTROL RING [15] PRESSES THE COMPRESSION HELICOIDAL SPRINGS [ 12] AND PUSH THE CLAMPING WEDGES [4] BACK, ALLOWING THE MAIN CENTRIFUGAL LOCKERS [3] TO RETURN, FOR THE CONTACT WHEEL [1] TO CHANGE GAUGE. THE MAIN CENTRIFUGAL BLOCKERS [3] KEEP THE CONTACT WHEEL [1] STRONGLY PRESSED AGAINST THE FLAGS [6] OR [7] OF THE BASE WHEEL [2], DEPENDING ON THE GAUGE IN USE, IN ORDER TO OBTAIN A SIMILAR RIGIDITY TO A ONE-BLOCK WHEEL.
