Problems solved by technology
However, the structure of the coupler is complicated and the mass is very large, which increases the load of the train. Especially when the train is turning, the bogie guides the train to run along the track, and the traction force is transmitted between two adjacent trains through the coupler, so that the distance between the train and the track The pressure load between them increases, causing the train to run unsteadily
[0004] To sum up, the support and connection structure of the current trains lead to a heavy weight of the train, which affects the running stability of the train when turning

The invention provides a train supporting device and a train. The train supporting device comprises a hinging steering frame and a supporting steering frame, wherein the hinging steering frame comprises a first framework and two first air springs positioned on the first framework; the two first air springs are jointly provided with a first additional air chamber and a first height control valve; the supporting steering frame comprises a second framework and two second air springs positioned on the second framework; each of the two second air springs is provided with a second additional air chamber and a second height control valve; the hinging steering frame is used for connecting two adjacent sections of a train body; and the supporting steering frame is positioned under a single section of the train body, and is used for supporting the single section of the train body. According to the train supporting device provided by the invention, the whole weight of the train is reduced, and the operating performance of the train is improved.
Description
technical field [0001] The invention relates to the field of rail vehicles, in particular to a train support device and a train. Background technique [0002] Rail vehicles are composed of car body, car body connection device, car body support device, power device, brake device and other parts. Wherein, the vehicle body connection device is usually a coupler, which realizes the connection between the vehicle body and the vehicle body, is used to transmit traction and impact force, and keeps a certain distance between two adjacent vehicle bodies. The car body support device is usually a bogie, which is used to guide the vehicle along the track and bear various loads from the car body and the line. [0003] At present, one car body is usually supported by two bogies, that is, two adjacent car bodies have a total of four bogies, and the two adjacent car bodies are connected by couplers. However, the structure of the coupler is complicated and the mass is very large, which inc...
