Abstract

Una unidad de vehículo ferroviario, que comprende: - un primer componente de vehículo (104), - un segundo componente de vehículo (111) y - un dispositivo de soporte de rodamiento (112); - contrarrestando dicho dispositivo de rodamiento (112) el movimiento de rodamiento entre dicho primer componente de vehículo (104) y dicho segundo componente de vehículo (111) alrededor de un eje de rodamiento; - comprendiendo dicho dispositivo de soporte de rodamiento (112) una barra de torsión (112.1), un primer brazo de torsión (112.2) y un segundo brazo de torsión (112.3); - estando dicho primer brazo de torsión (112.2) rígidamente conectado de manera rotativa a una primera sección terminal de dicha barra de torsión (112.1) y estando articulado con dicho primer componente de vehículo (104); - estando dicho segundo brazo de torsión (112.3) conectado rígidamente de manera rotativa a una segunda sección terminal de dicha barra de torsión (112.1) y estando articulado con dicho primer componente de vehículo (104); - estando dicha barra de torsión (112.1) montada de forma pivotante a dicho segundo componente de vehículo (111) por medio de un primer elemento de soporte (113.1) y de un segundo elemento de soporte (113.2), estando dicho primer elemento de soporte (113.1) y dicho segundo elemento de soporte (113.2) separados mutuamente por una distancia a lo largo de un eje de la barra de torsión longitudinal (112.6) de dicha barra de torsión (112.1); caracterizada porque - al menos se dispone un elemento intermedio (114.1, 114.2); - estando dicho elemento intermedio (114.1, 114.2) conectado a dicho segundo componente de vehículo (111) y cooperando con dicha barra de torsión (112.1); - estando dicho elemento intermedio (114.1, 114.2) situado entre dicho primer elemento de soporte (113.1) y dicho segundo elemento de soporte (113.2) - dicho elemento intermedio (114.1, 114.2) comprende un elemento de amortiguación (114.3), - cooperando dicho elemento de amortiguación (114.3) con dicha barra de torsión (112.1) para amortiguar las vibraciones de flexión de dicha barra de torsión (112.1) alrededor de un eje de flexión que discurre transversalmente con respecto a dicho eje de barra de torsión (112.6).A railway vehicle unit, comprising: - a first vehicle component (104), - a second vehicle component (111) and - a bearing support device (112); - counteracting said bearing device (112) the rolling movement between said first vehicle component (104) and said second vehicle component (111) about a bearing axis; - said bearing support device (112) comprising a torsion bar (112.1), a first torsion arm (112.2) and a second torsion arm (112.3); - said first torsion arm (112.2) being rigidly rotatably connected to a first terminal section of said torsion bar (112.1) and being articulated with said first vehicle component (104); - said second torsion arm (112.3) being rigidly connected rotatably to a second terminal section of said torsion bar (112.1) and being articulated with said first vehicle component (104); - said torsion bar (112.1) being pivotally mounted to said second vehicle component (111) by means of a first support element (113.1) and a second support element (113.2), said first support element being (113.1) and said second support element (113.2) mutually separated by a distance along an axis of the longitudinal torsion bar (112.6) of said torsion bar (112.1); characterized in that - at least one intermediate element is provided (114.1, 114.2); - said intermediate element (114.1, 114.2) being connected to said second vehicle component (111) and cooperating with said torsion bar (112.1); - said intermediate element (114.1, 114.2) being located between said first support element (113.1) and said second support element (113.2) - said intermediate element (114.1, 114.2) comprises a damping element (114.3), - cooperating said damping element (114.3) with said torsion bar (112.1) to dampen the bending vibrations of said torsion bar (112.1) around a bending axis that runs transversely with respect to said torsion bar axis (112.6).
