Embodiment Construction

[0026] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0027] like figure 1 As shown, a rail vehicle skirt is arranged at the bottom of the car body 1 to provide protection for the equipment at the bottom of the car body 1, including two types of movable skirt 2 and fixed skirt 3, and a movable skirt 2 is installed at the bottom of the car body 1 The order of a fixed skirt plate 3 is arranged successively.

[0028] Both the movable skirt 2 and the fixed skirt 3 are non-full-covered equipment compartment structures, and there is no need to fix them with the car body 1 at the bottom of the skirt. The movable skirt 2 and the fixed skirt 3 are both aluminum profile skirts, which are light in weight. The movable skirt board 2 is a skirt board structure that can be turned over and opened.

[0029] like figure 2 As shown, the top of the movable skirt 2 is suspended and installed on the vehicle body 1 t...

Abstract

The invention relates to a skirt plate of a railway vehicle. The top of the shirt plate is hung on and fixed to a vehicle body through a rotating shaft, and the shirt plate rotates with the rotating shaft serving as the center. The shirt plate is simple in structure, light in weight and capable of being flexibly opened and closed, due to slide grooves, parts can be connected with the shirt plate through bolts without welding, and the installation position can be adjusted according to the size error.

Description

technical field [0001] The invention relates to a skirt, in particular to a rail vehicle skirt. Background technique [0002] Usually, the equipment compartment under the EMU is fully sealed or fully covered, and the skirt plate is connected with the frame and bottom plate of the equipment compartment with bolts to form an overall frame structure. To open the position where the skirt board needs to be inspected, open a separate inspection door on the skirt board, or remove the entire skirt board. [0003] However, some rail vehicles do not need the protection of the fully-enclosed equipment compartment, but only partial protection on the side of the vehicle, so a skirt that can be opened and closed flexibly is needed. Moreover, most of the skirt plates of this part of rail vehicles are carbon steel welded structures, which have the disadvantages of heavy weight, complex structure, and difficult control of processing quality. Contents of the invention [0004] The main pu...
