Abstract

The invention discloses a flexible framework of a bogie of a railway wagon and the railway wagon. The flexible framework includes: an L-shaped beam which comprises an end beam and a side beam A, wherein the side beam A is provided with an L-shaped beam mounting hole, and a first spherical center plate is arranged at the bottom of the L-shaped beam mounting hole; a T-shaped beam which comprises a side beam B and a cross beam, wherein a T-shaped beam mounting seat is arranged at one end, far away from the side beam B, of the cross beam, the T-shaped beam mounting seat can be inserted into the L-shaped beam mounting hole, an elastic cushion block is arranged on the upper surface of the T-shaped beam mounting seat; a second spherical center plate is arranged on the lower surface of the T-shaped beam mounting seat, and the second spherical center plate can be matched with the first spherical center plate; and a connecting component which comprises a connecting bolt, an elastic spherical hinge and a connecting seat, wherein the connecting component is used for elastically connecting the L-shaped beam and the T-shaped beam. According to the flexible framework disclosed by the invention, the two side beams can be relatively independent in three directions.

Description

technical field [0001] The invention relates to a railway freight car bogie frame and a railway freight car, in particular to a railway freight car bogie flexible frame and a railway freight car. Background technique [0002] At present, the world rail vehicle freight car bogies mainly include two structural types: three-piece type and integral welding type. Among them, the frame is the basis of the bogie, which forms a whole of the parts of the bogie. The frame mainly plays the role of bearing and transmitting various forces and loads, and its structural size meets the structure, shape and assembly requirements of each component. [0003] The traditional three-piece bogie frame is freely connected by side frames and bolsters through central suspension springs. It has the characteristics of simple structure, low cost, large bearing capacity, adaptable to complex lines and low operating speed, but the structure is loose and cannot adapt to high-speed vehicles. Running, and ...
