Description

Technical Field

[0001] The utility model relates to the technical field of trains, in particular to a lightweight train body. Background Art

[0002] A train refers to a set of vehicles, which is divided into two types: railway trains and road trains. A railway train is a vehicle that runs on railway tracks and is usually composed of multiple carriages. It is used to transport goods or passengers, but the existing train bodies have certain inconveniences in use.

[0003] First, the existing train body structure is not lightweight enough, which easily increases the vehicle's operating costs during operation. Second, the existing train body structure design is not optimized enough to distribute the generated load, resulting in poor service strength. To this end, we propose a lightweight train body.

[0009] Preferably, the chassis is welded to the bolster, and an outer surface of one end of the bolster is provided with an empty spring seat, a traction rod and a shock absorber interface.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] Changing the original four windows between the two doors of the side wall to three windows, that is, reducing the nine side beams to eight, can effectively reduce the weight of the car body and effectively reduce the train operating costs; the bolster and the chassis are connected together by welding, which can effectively transfer the longitudinal load from the suspension frame to the chassis, and the bolster is welded laterally to the lower chord beam of the side wall, which can transfer the lateral load from the suspension frame to the side wall structure.

[0018] Specifically, in this embodiment, it includes a base frame 1, and the upper end outer surface of the base frame 1 is provided with side walls 2 and side beams 3, and the side beams 3 are located on both sides of the side walls 2. The outer surfaces of both ends of the base frame 1 are provided with end walls 4, and the upper end outer surface of the side beams 3 is provided with a cross beam 5. The original four windows between the two doors of the side wall 2 are changed to three windows, that is, the nine side beams 3 are changed to eight, which can effectively reduce the weight of the car body and effectively reduce the train operation cost. The upper end outer surface of the cross beam 5 is provided with a roof 6, and a top beam 7 is provided between the ceiling 6 and the cross beam 5. The lower end outer surface of the base frame 1 is provided with a pillow beam 8 and a coupler seat 9, and the coupler seat 9 is located on both sides of the pillow beam 8.

[0019] The lightweight train body provided by the present invention changes the original four windows between the two doors of the side wall 2 into three windows, that is, the nine side beams 3 are changed into eight, which can effectively reduce the weight of the body and effectively reduce the train operation cost.

[0020] In one embodiment provided by the present invention, the base frame 1 is welded to the side beam frame 3, and the outer surfaces of both sides of the side wall 2 are fixedly connected to the outer surfaces of both sides of the side beam frame 3. When in use, the side beam frame 3 is mainly used to fix the side wall 2 and can provide support for the side wall 2.
