Abstract

La presente divulgación se relaciona con el campo técnico de un chasis de vehículo ferroviario, y proporciona una estructura de un chasis final para un vehículo ferroviario y un vehículo ferroviario que incluye lo mismo, e incluye una viga de tracción y un par de placas de soporte superiores respectivamente montadas en ambos lados de la viga de tracción y un par de placas de soporte inferiores dispuestas opuestamente debajo del par de placas de soporte superiores. Los lados de las placas de soporte superiores y los lados de las placas de soporte inferiores de las placas de soporte superiores forman una superficie de soporte superior para soportar los pisos y las superficies inferiores de las placas de soporte inferiores forman una superficie de montaje inferior de las interfaces de componentes. En una realización de la presente divulgación, debido a que la estructura de vigas transversales previa se reemplaza con la estructura que incluye las placas de soporte superiores e inferiores para soportar los pisos, el área de soporte aumenta en gran medida, la capacidad de soporte también aumenta en gran medida, y aumenta la presión. Cuando la presión actúa sobre las placas de soporte, el área de soporte de fuerzas es mayor, se dispersa la fuerza, se evita la deformación originada por la concentración de presión local, y aumentan la fuerza y rigidez general; el área de interfaz de la parte inferior del chasis aumenta mediante la disposición de las placas de soporte inferiores, de manera tal que las áreas de montaje de los componentes aumentan y es más razonable y simple disponer las posiciones de los componentes.The present disclosure relates to the technical field of a rail vehicle chassis, and provides an end chassis structure for a rail vehicle and a rail vehicle that includes the same, and includes a draw beam and a pair of support plates. respectively mounted on both sides of the draw beam and a pair of lower support plates arranged oppositely below the pair of upper support plates. The sides of the upper support plates and the sides of the lower support plates of the upper support plates form an upper support surface to support the floors and the lower surfaces of the lower support plates form a lower mounting surface of component interfaces. In one embodiment of the present disclosure, because the previous transverse beam structure is replaced with the structure including the upper and lower support plates to support the floors, the support area is greatly increased, the bearing capacity is also greatly increased. increases greatly, and pressure increases. When the pressure acts on the support plates, the force support area is larger, the force is dispersed, the deformation caused by the local pressure concentration is avoided, and the general strength and stiffness increase; The interface area of the bottom of the chassis is increased by the arrangement of the lower support plates, so that the mounting areas of the components are increased and it is more reasonable and simple to arrange the positions of the components.
