Problems solved by technology

However, the hanging installation method of the under-vehicle equipment has the disadvantage of poor installation stability, which makes the under-vehicle equipment easy to fall out of the suspension structure when the vehicle is running and drives the under-vehicle equipment to vibrate.

Abstract

The invention relates to the technical field of railway vehicles, and provides a bottom frame boundary beam, a vehicle body bottom frame, a railway vehicle body and a railway vehicle. The bottom frameboundary beam comprises a boundary beam body and an equipment pulling and hanging part. The boundary beam body comprises an outer side beam and an inner side beam. The equipment pulling and hanging part is arranged on one side, back to the outer side beam, of the inner side beam; the equipment pulling and hanging part comprises a supporting transverse rib, a shielding longitudinal rib and a connecting inclined rib; and one end of the supporting transverse rib is connected with the inner side beam, the other end of the supporting transverse rib is connected with the bottom of the shielding longitudinal rib, the top of the shielding longitudinal rib is connected with one end of the connecting inclined rib, the other end of the connecting inclined rib is connected with the inner side beam, and the connecting inclined rib, the inner side beam, the supporting transverse rib and the shielding longitudinal rib define an under-vehicle equipment mounting cavity. According to the bottom frame boundary beam provided by the embodiment of the invention, pulling and hanging installation of under-vehicle equipment can be realized, the under-vehicle equipment is effectively prevented from fallingoff, and installation stability and reliability of the under-vehicle equipment are effectively improved.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to an underframe side beam, a vehicle body underframe, a rail vehicle body and a rail vehicle. Background technique [0002] The underframe side beam is the main load-bearing structure of the rail vehicle body. As one of the most critical connecting parts of the rail vehicle body, it is necessary to connect the underframe floor, side walls, corbels, buffer beams, end walls and other components into a whole . [0003] At present, when the rail vehicle is installing the equipment under the vehicle, a suspension structure such as a floor chute is usually provided on the side beam of the underframe, and the suspension installation of the equipment under the vehicle is realized through the suspension structure. However, the hanging installation method of the under-vehicle equipment has the disadvantage of poor installation stability, so that when the vehicle runs to drive the unde...
