Rail vehicle head-car structure

Abstract

The invention discloses a rail vehicle head-car structure which comprises a vehicle body main structure, a cab framework and an anti-creeper installing structure. The anti-creeper installing structure is of a T-shaped double-layer box-type structure, the two side ends of the anti-creeper installing structure are fixedly connected with an underframe boundary beam and a car coupler mounting base on the corresponding side, and the upper portion of the anti-creeper installing structure is covered with a cab floor. The rail vehicle head-car structure has very good longitudinal and vertical intensity and rigidity, a single anti-creeper installing area can bear longitudinal compressing force of 600 kN and vertical weight of 13 t, the longitudinal direction regulating amount is large, the vehicle body floor can be approached infinitely, and the problem of matching with an existing line vehicle is solved. The reliance on intensity of the front end of the underframe boundary beam is greatly reduced, and streamline modeling is achieved.

Description

technical field [0001] The invention relates to a head car structure of a rail vehicle, and belongs to the technical field of body structures of rail vehicles. Background technique [0002] At present, there are two main types of subway vehicle body: one structure with riveting (or bolt connection), such as the structure described in Chinese patent application No. The front end of the frame is an independent module, which is connected to the main structure of the car body through bolts or rivets. The side beams of the under frame generally do not extend to the driver's cab door area; The frame side member of the part is full length, ie extends from the passenger compartment area to the front of the driver's door area. The front end of the former head car can be designed as an independent driver's cab frame and glass fiber reinforced plastic hood. The head shape changes a lot, but the riveted structure car body has heavy weight, poor sealing during the whole life cycle, and ...

AI Technical Summary

Problems solved by technology

[0005] 1) The height adjustment range of the anti-climbing device from the rail surface is limited, which reduces the degree of meshing and matching with the anti-climbing device of vehicles on existing lines, and it is difficult to meet the climbing requirements stipulated in the EN 15227 standard;

[0006] 2) The side beam of the underframe needs to extend a long distance from the anti-climber mounting plate, which causes the arc inflection point of the hood to move forward, and the length and shape of the arc section of the hood are limited, which is extremely unfavorable to the shape design and is likely to cause various The appearance of this model lacks the sense of change
