Embodiment Construction

[0041] In the present invention, unless otherwise clearly specified and limited, terms such as "installation", "connection", "connection" and "fixation" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection , or integrated; it can be directly connected or indirectly connected through an intermediary, it can be the internal communication of two elements or the interaction relationship between two elements. The "first", "second" and similar words mentioned in this application do not indicate any order, quantity or importance, but are only used to distinguish different components. Likewise, words like "a" or "one" do not denote a limitation in number, but indicate that there is at least one. In the implementation of this application, "and / or" describes the association relationship of associated objects, indicating that there may be three types of relationships, for example, A and / or B, which may mean: A exists alone, A and B e...

Abstract

The invention belongs to the technical field of high-speed trains, and specifically discloses a high-speed train aerodynamic control telescopic wing device, a high-speed train and a control method; Wing structure; the telescopic wing structure includes the telescopic wing one installed on the support base, the telescopic wing unit set in the telescopic wing one and moving along the axial direction of the telescopic wing one, and the telescopic wing unit installed in the telescopic wing one and controlling the movement of the telescopic wing unit telescoping mechanism. And the high-speed train based on the telescopic wing device and the control method of the telescopic wing device; the present invention provides the necessary lift for the whole vehicle during normal operation, so as to reduce the pressure on the wheels without causing the train to derail; When the train is running in a special environment with cross wind, by controlling the telescopic wing unit, only provide lift on the leeward side of the cross wind to resist the lateral force generated by the cross wind, which helps to maintain the smooth operation of the train.

Description

technical field [0001] The invention relates to the technical field of high-speed trains, and more specifically, relates to a telescopic wing device for high-speed train aerodynamic control, a high-speed train and a control method. Background technique [0002] At present, the speed of high-speed trains running in my country is between 200 and 400 km / h, and the running speed of many railway lines is maintained at 300 to 350 km / h. Maintaining such a high-speed running state has put forward high requirements for high-speed train wheel components . As the connecting part between the car body and the rail, the stability and reliability of the wheel is an important guarantee for the smooth and comfortable operation of the train. However, as a high-speed running part, the wear of the wheel is unavoidable, especially when the train is running under a heavy load, it will cause more serious damage to the wheel. When the wheel wears a lot, it will cause the tread surface of the wheel...
