Abstract

The invention provides an underfram assembly of a rail vehicle and a rail vehicle. The underframe assembly comprises two lower side beams arranged at intervals and a plurality of cross beams arrangedbetween the two lower side beams, the plurality of cross beams are arranged at intervals along the length direction of the lower side beams, at least one lower side beam is provided with a connectingseat, and at least one end of the cross beam is connected with the lower side beam through the connecting seat. By applying the technical proposal of the invention, the connecting strength between thecross beam and the lower side beam is increased by converting the connecting seat into surface contact, and the strength and the rigidity requirements of the underframe assembly are ensured.

Description

technical field [0001] The invention relates to the field of rail vehicles, in particular to a chassis assembly of a rail vehicle and the rail vehicle. Background technique [0002] The connecting structure of the crossbeam and the side beam in the underframe assembly in the prior art is the main load-bearing structure. During the assembly process of the chassis components, the beam and the lower side beam are usually directly connected by welding or clamping, so that a line-surface contact is formed between the beam and the side beam, and the connection strength of the base component cannot be guaranteed. Contents of the invention [0003] The main purpose of the present invention is to provide an underframe assembly of a rail vehicle and the rail vehicle, so as to solve the problem of low connection strength between the lower side beam and the cross beam in the prior art. [0004] In order to achieve the above object, according to one aspect of the present invention, th...
