Title (EN) GAUGE-CHANGEABLE WHEELSET FOR RAILWAY VEHICLE
(FR) ENSEMBLE ROUE A MODIFICATION DE CALIBRE POUR VEHICULE DE CHEMIN DE FER
Abstract: front page image
(EN)A gauge -adjustable wheelset for railway vehicles is disclosed. The gauge -adjust able wheelset of the present invention automatically changes a gauge thereof, such that the railway vehicle travels between two kinds of railways having different gauges. The gauge-adjustable wheelset includes an axle (100) , which has a sliding part (110) and a cap mounting part (120) thereon, a wheel (200) , which is movably fitted over the sliding part (11) , and a support cap (300) , which is securely fitted over the cap mounting part (120) . The gauge -adjustable wheelset further includes a locking block (500) , which is rotatably fitted over the support cap (300) , so that lateral movement of the wheel is controlled by rotation of the locking block (500) , and a flange (400) , which controls locking or unlocking operation of the locking block (500) . The gauge -adjust able wheelset further includes a spring holder (700) and a compression spring (600) , provided between the flange (400) and the spring holder (700) .
(FR)L'invention porte sur un ensemble roue à calibre réglable pour véhicules de chemin de fer. Cet ensemble roue à calibre réglable change automatiquement de calibre de sorte que le véhicule chemin de fer se déplace entre deux types de voies ferrées possédant des calibres différents. Cet ensemble roue à calibre réglable comprend un essieu (100) comportant une pièce coulissante (110) sur laquelle est placée une pièce de fixation de manchon (120), une roue (200) montée amovible sur la pièce coulissante (110) et un manchon de support (300) fixé solidement sur la pièce de fixation (120). L'ensemble roue à calibre réglable comprend également un bloc de verrouillage (500) monté rotatif sur le manchon de support (300) de sorte que le mouvement latéral de la roue soit commandé par la rotation du bloc de verrouillage (500), et une bride (400) qui commande le verrouillage ou le déverrouillage du bloc (500). L'ensemble roue à calibre réglable comprend en outre un dispositif de retenue (700) de ressort et un ressort de compression (600) ménagé entre la bride (400) et le dispositif de retenue (700) du ressort.
