Embodiment 1

[0070] Such as figure 1 and figure 2 As shown, the bogie cabin 102 for a rail vehicle in the embodiment of the present application includes a cabin assembly, and the cabin assembly includes:

[0071] main deck 1021;

[0072] Two side decks 1022, the two side decks 1022 are fixed on both sides of the main deck 1021, and enclose with the main deck 1021 a cavity for accommodating the rail vehicle bogie 101;

[0073] Wherein, the inner side of the main deck is fixed to the front or rear of the bogie, separating the front or rear of the bogie from the outside world; the inner sides of the two side decks are fixed to the sides of the bogie to separate the bogie from the outside. The sides are separated from the outside world.

[0074] The bogie cabin for a rail vehicle according to the embodiment of the present application includes a cabin assembly, the cabin assembly includes a main deck and two side decks, and the two side decks are fixed on both sides of the main deck. In th...

Embodiment 2

[0173] The bogie system of the embodiment of the present application includes:

[0174] bogie;

[0175] In the bogie compartment of Embodiment 1, the inner side of the bogie compartment is connected to the bogie, a first preset distance is maintained between the main deck and the bogie, and the side deck is connected to the steering maintaining a second preset interval between the racks;

[0176] The main deck is a main deck of a composite material, and the side deck is a side deck of a composite material.

[0177] The bogie of the bogie system of this embodiment also includes a crossbeam, and the bogie is suitable for rail vehicles, which can be diesel locomotives or electric locomotives, EMUs, subways, light rails or trams, etc., can be For passenger vehicles or freight vehicles.

[0178] In addition to the beam, the bogie also includes side beams, wheelsets, traction devices, suspension devices and other components.

[0179] In this embodiment, the horizontal direction ...

specific Embodiment approach

[0185] The beam is made of cast aluminum alloy or other lightweight materials, and the cast mold can be made with additive manufacturing technology to reduce weight.

[0186] Such as Figure 17 As shown, the width of the end of the beam main body 21 facing the other beam monomer 2 is relatively large, which is greater than the width of the middle part of the beam main body 21 . The end face of the beam main body 21 facing the other beam monomer 2 is called the inner end face, and the first installation area and the second installation area are respectively located on the inner end face of the beam main body 21, specifically arranged at both ends along the width direction of the inner end face.

[0187] There is a certain distance between the first installation area and the second installation area, so that there is a certain gap between the two beam connecting arms 22 for accommodating the towing center pin in the bogie traction device. The top of the traction center pin is c...

Abstract

The embodiment of the invention provides a bogie cabin for a railway vehicle, and a bogie system. The bogie cabin comprises a cabin body assembly, and the cabin body assembly comprises a main cabin plate and two side cabin plates fixed to the two sides of the main cabin plate, wherein a concave cavity used for containing a railway vehicle bogie is defined by the two side cabin plates and the maincabin plate. The inner side of the main cabin plate is used for being fixed to the front portion or the rear portion of the bogie, and the front portion or the rear portion of the bogie is separated from the outside. The inner sides of the two side cabin plates are used for being fixed to the side of the bogie to separate the side of the bogie from the outside. The bogie system comprises the bogiecabin. According to the embodiment of the invention, the technical problems of large noise and aerodynamic resistance of a bogie system are solved.

Description

technical field [0001] The present application relates to the technical field of rail vehicles, and in particular, relates to a bogie cabin and a bogie system for rail vehicles. Background technique [0002] The existing bogie has relatively high noise and great interference to the outside world. Aerodynamic resistance is one of the key indicators affecting the speed-up of high-speed trains, and good resistance characteristics are also an important symbol of energy-saving and environmental protection of trains. The main sources of aerodynamic resistance of high-speed trains include: surface friction, head-to-tail vehicle pressure difference resistance, bogie, pantograph system, workshop clearance, etc. Among them, the aerodynamic resistance of the bogie area and the equipment under the train can reach 22% to 53% of the total aerodynamic resistance of the train. Therefore, reducing the aerodynamic drag at the bottom of the train is an important issue for aerodynamic drag re...
