Abstract

The invention provides an underframe assembly of a rail vehicle and a rail vehicle. The underframe assembly comprises: a lower side beam, two lower side beams, and two lower side beams are arranged atintervals; a cross beam assembly arranged between two lower side beams, wherein the cross beam assemblies are a plurality of, and the plurality of cross beam assemblies are arranged at intervals along the length direction of the lower side beams; the at least one cross member assembly includes a first cross member and a second cross member disposed below the first cross member in a height direction of the lower side member, the first cross member and the second cross member form a mounting cavity, and a part of the floor of the rail vehicle is disposed in the mounting cavity. The technical proposal of the invention can increase the interior space of the vehicle on the basis of ensuring the connection strength between the cross beam assembly and the floor.

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] As the main load-bearing structure of the car body, the underframe assembly not only bears the weight of the car body itself and all the equipment in the car, but also transmits traction and braking forces as well as complex dynamic stress. Therefore, the underframe assembly must have sufficient strength and certain stiffness. [0003] In the prior art stainless steel car body, the underframe assembly includes two side rails and multiple cross beams, the multiple cross beams are arranged at intervals along the length direction of the bottom side rails, the cross-sectional shape of the cross beams is C-shaped, and the metal floor covers the cross beams and the bottom side rails Above, the interior space of the car is isolated from the equipment under the car under the chassis assembly through the...
