Abstract

The embodiment of the invention provides a chassis assembly of a railway vehicle and the railway vehicle. The chassis assembly of the railway vehicle comprises a pair of edge beams, a pair of end beams and connecting angle plates. The pair of edge beams extends in the length direction of the under-frame assembly, and first notch parts are arranged at the ends of the edge beams. The pair of end beams are arranged at the two ends of the edge beams respectively, the two ends of each end beam are connected with the ends of the pair of edge beams respectively, the two ends of each end beam are each provided with a second notch part, the first notch parts and the second notch parts are spliced in a one-to-one correspondence and crossed mode, and connecting notches are defined by the splicing positions of the first notch parts and the second notch parts. The connecting angle plates are embedded in the connecting notches, and the edges of the connecting angle plates are spliced with the edges of the connecting notches in a one-to-one correspondence mode. By the adoption of the scheme, the total length of the welding seam is increased, the connection reliability is improved, the connecting corner plate can reinforce the connecting position, the installation space cannot be additionally occupied, and therefore follow-up installation and maintenance of equipment cannot be affected.

Description

technical field [0001] The present application relates to the vehicle body structure technology of a rail vehicle, in particular, to an underframe assembly of a rail vehicle and the rail vehicle. Background technique [0002] Among the components that make up the rail vehicle body, the underframe is the carrier of other large components. During the operation of the rail vehicle, the underframe bears the longitudinal dynamic load, static load and impact load of the car body. Therefore, the composition of the rail vehicle chassis needs to meet the performance requirements of high strength, load resistance, impact resistance, fatigue resistance, etc., and one of the keys to restrict these performance indicators is the connection method of the side beams and end beams of the chassis. The side girders and end girders of the conventional rail vehicle underframe are cross-connected through the side girders and end girders, and the triangle ribs are welded at the angle formed by the...
