Embodiment 1

[0066] Such as figure 1 and figure 2 As shown, the bogie system of the rail vehicle in the embodiment of the present application includes a bogie 101 and a bogie cabin 102, and the bogie cabin includes a cabin assembly, and the cabin assembly includes:

[0067] main deck 1021;

[0068] 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 rail vehicle bogies;

[0069] 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.

[0070] The bogie system of the rail vehicle in the embodiment of the present application includes a bogie and a bogie cabin, and the bogie cabin includes a cabin assembly. The cabin assembly includes...

Embodiment 2

[0170] On the basis of the bogie system in Embodiment 1, the bogie system of the embodiment of the present application has the following features.

[0171] 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.

[0172] In addition to the beam, the bogie also includes side beams, wheelsets, traction devices, suspension devices and other components.

[0173] In this embodiment, the horizontal direction that is the same as the traveling direction of the vehicle is called the longitudinal direction, the horizontal direction that is perpendicular to the longitudinal direction is called the horizontal direction, and the direction that is perpendicular to the horizontal direction is called the vertical or vertical direction. The beams extend transversely in the bogie. ...

specific Embodiment approach

[0179] 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.

[0180] 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.

[0181] 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 system of a railway vehicle, and the railway vehicle. The bogie system comprises a bogie and a bogie cabin, the bogie cabin comprises a cabin body assembly, the cabin body assembly comprises a main cabin plate and two side cabin plates fixed to the two sides of the main cabin plate, and a concave cavity used for containing a railway vehicle bogie isdefined by the two side cabin plates and the main cabin plate; the inner side of the main cabin plate is fixed to the front portion or the rear portion of the bogie, and the front portion or the rearportion of the bogie is separated from the outside; and the inner sides of the two side cabin plates are fixed to the side of the bogie, and the side of the bogie is separated from the outside. The railway vehicle comprises the bogie system. 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 field of rail vehicle technology, in particular, to a rail vehicle bogie system and a rail vehicle. 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 reduction of high-...
