Description

  The present invention comprises a roof structure that constitutes an upper wall of a vehicle body, a side structure that constitutes a side wall, a frame that constitutes a lower wall, and a wife structure that constitutes an end wall in the longitudinal direction, the roof structure, the side structure, and the frame At least one of the two face plates facing each other is connected by a plurality of ribs, and at least one of the entrances and exits provided in the side structure is connected to the frame and closer to the center than the carriage supporting the vehicle body The present invention relates to a railway vehicle structure.

  A railway vehicle structure generally includes a roof structure that constitutes the upper wall of the vehicle body, a side structure that constitutes the side wall, a base frame that constitutes the lower wall, and a wife structure that constitutes the end wall in the longitudinal direction. In recent years, for the purpose of weight reduction and improvement of manufacturability, a roof structure, a side structure, a base frame, etc., are made of an aluminum alloy hollow extruded shape composed of two facing face plates and a plurality of ribs connecting the face plates. The method of constructing and assembling a railway vehicle structure using materials is becoming widespread.

  Here, the side structure is generally provided with an entrance for passengers to get on and off. There are two or more entrances and exits for suburban vehicles, and the width of the entrance and exit is large in order to enable getting on and off in a short time. Further, in order to make the entire train vehicle as uniform as possible, it is often arranged closer to the center than the carriage arranged in the vicinity of the end portion of each vehicle when viewed in the longitudinal direction.

  In such a configuration, the railcar structure is deformed as shown in FIG. Due to the mass of passenger equipment, mainly large transformers and main transformers installed under the floor, and the mass of passengers, the car body is greatly deformed downward with the carriages 200 and 200 as support points, particularly in the region between the two support points. To do. In particular, deformation is concentrated in the vicinity of an entrance / exit that is a large opening.

  If such downward deformation occurs excessively, vibration during traveling increases, and the riding comfort of the railway vehicle deteriorates. For this reason, a method is adopted in which a strong entrance / exit frame (indicated by 90 in FIG. 7) is welded to suppress deformation near the entrance / exit that is caused by concentrated deformation (see Patent Document 1 as an example). However, there has been a problem that the structure of the railway vehicle is greatly distorted due to the great heat generated when welding the thick doorway frame. In addition, a method has also been proposed in which a reinforcing member is welded to a portion other than the doorway to suppress deformation of the entire railway vehicle structure (see Patent Document 2 as an example). However, in suburban vehicles where most of the deformation occurs near the doorway, the deformation may not be sufficiently suppressed.

At least one of the face plates is formed of a hollow extruded member connected by ribs, and the side structure is provided with an entrance for passengers to get on and off, and at least one of the entrances is the platform. In the railroad vehicle structure arranged closer to the longitudinal center of the railroad vehicle structure than the carriage connected to the frame and supporting the car body, the roof at a position corresponding to the longitudinal direction of the railcar structural body at the doorway A beam-like or plate-like reinforcing member extending in the width direction of the railway vehicle structure is joined to the face plate inside the structure by a mechanical fastening method such as a bolt or a rivet, or the access A beam-like or plate-like reinforcing member extending in the height direction of the railway vehicle structure is attached to the face plate inside the side structure at a position corresponding to the longitudinal direction of the railway vehicle structure, such as a bolt or a rivet. The railway is connected to the lower part of the side beam located at the end in the width direction of the railroad vehicle structure of the underframe in the longitudinal direction of the railcar structure at the entrance and exit of the railroad vehicle structure. A beam-like or plate-like reinforcing member extending in the longitudinal direction of the vehicle structure is coupled by a mechanical fastening method such as a bolt or a rivet, or the longitudinal direction of the railway vehicle structure at the doorway is Extending in the longitudinal direction of the railroad vehicle structure to the face plate inside the eaves located at the upper end of the railcar structure in the height direction of the side structure or the widthwise end of the railcar structure of the roof structure Do That the Jo or plate-like reinforcing member together by mechanical fastening techniques such as bolts or rivets, are comprised.

  According to this railway vehicle structure, the reinforcing member described above is coupled to the roof structure, side structure, underframe, etc. by a mechanical fastening method such as a bolt or rivet in the vicinity of the entrance / exit of the railway vehicle structure. Since the thick members are not joined by welding, it is possible not only to prevent the occurrence of distortion due to welding, but also to have a strong structure in the vicinity of the entrance / exit and sufficiently suppress deformation in the vicinity of the entrance / exit. Furthermore, since the reinforcing member is coupled with a bolt or a rivet that is easy to fasten, construction efficiency can be improved.
