Problems solved by technology

[0004] When the collision occurs, the anti-climbing device has completed the energy absorption function, but if the collision process is still in progress, the cab structure will be further compressed, but the cab underframe structure in the prior art only has a load-bearing function, and itself does not have energy absorption Function, the deformation of the underframe structure is uncontrollable, which will cause the underframe structure to warp upward or downward under the impact force, and there is still the risk of climbing, which will endanger the life safety of the driver

Abstract

The invention provides an energy-absorbing beam, a cab chassis structure of a rail vehicle and a rail vehicle. The energy-absorbing beam is connected with the cab chassis structure of the rail vehicle. The energy-absorbing beam comprises a cylindrical shell and at least one partition plate located inside the shell. The cross-sectional area of the housing gradually decreases in the direction from the rear end of the cab to the front end of the cab; The partition plate is connected with the inner wall of the shell, and the plane direction of the partition plate is mutually perpendicular to the traveling direction of the rail vehicle; A V-shaped notch is formed on the outer wall of a part of the outer shell facing the front of the rail vehicle, and a corner plate matching the shape of the V-shaped notch is welded on the V-shaped notch, thereby improving the collision-proof and energy-absorbing function of the cab chassis structure.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to an energy-absorbing beam, an underframe structure of a driver's cab of a rail vehicle and the rail vehicle. Background technique [0002] There are many types of rail vehicles, mainly including: underground subway trains, express rail and light rail trains connecting the city center and suburbs, and trams that shuttle through the bustling areas of the city. [0003] The anti-collision passive safety design of rail vehicles is an important guarantee for the safe operation of vehicles. The rail vehicle includes a car body and a driver's cab connected to one end of the car body. The driver's cab includes an underframe structure and a skeleton structure connected to the underframe structure. In order to prevent the vehicle from climbing, the prior art installs an anti-climbing Device, specifically, the anti-climbing device is installed on the front wall of the driver's cab, th...
