Problems solved by technology

Although this structure can meet the requirements of the existing railway bathtub open car, but for the large axle load railway bathtub open car, due to the increase of the axle load, the load of the vehicle will increase accordingly, resulting in an increase in the longitudinal impact force of the vehicle during driving , so that the impact force on the end plate of the bathtub is also increased, resulting in the deformation of the end plate of the bathtub and reducing its service life

Abstract

The invention provides a chassis of a railway bathtub open wagon, relating to a chassis on a railway bathtub open wagon, wherein the chassis provided by the invention is mainly used for solving the defects that the existing chassis cannot meet the use requirements of a macro-axis heavy-railway bathtub open wagon and the end plate of the bathtub is easy to deform and short in service life. The chassis in the invention comprises an end beam assembly, a longitudinal beam, a sleeper beam assembly, a side beam assembly, a bathtub composed of a bottom plate and an end plate, and a box-shaped traction beam composed of an upper cover plate, a web plate and a lower cover plate. The chassis is characterized in that both the tail end of the upper cover plate and the tail end of the web plate are welded with the end plate, wherein the tail end of the web plate is of a section-changing structure with a gradually enlarged section from the outside to the inside. The chassis has the advantages of simple structure, reduced weight of the traction beam, reduced longitudinal impact to the end plate of the bathtub and prolonged service life of the bathtub.

Description

technical field [0001] The invention relates to a railway bathtub gondola, in particular to an underframe on a railway bathtub gondola. Background technique [0002] The existing railway bathtub gondola car chassis includes end beam assembly, longitudinal beam, corbel assembly, side beam assembly, bathtub composed of bottom plate and end plate, and box-shaped frame composed of upper cover plate, web plate and lower cover plate. The traction beam, wherein, the web is a rectangular plate with the same cross-section at both ends, and the tail ends of the upper cover, web and lower cover are all welded to the end plate of the tub, and an additional Rib welded to end plate of bathtub. Although this structure can meet the requirements of the existing railway bathtub open car, but for the large axle load railway bathtub open car, due to the increase of the axle load, the load of the vehicle will increase accordingly, resulting in an increase in the longitudinal impact force of the...
