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 particularly discloses a high-speed train aerodynamic force regulation telescopic wing device, a high-speed train and a control method. The telescopic wing device comprises a supporting base and a telescopic wing structure which is installed on the supporting base and moves in the width direction of the high-speed train. The telescopic wing structure comprises a first telescopic wing installed on the supporting base, a telescopic wing unit which is arranged in the first telescopic wing in a sleeved mode and moves in the axial direction of the first telescopic wing, and a telescopic mechanism which is installed in the first telescopic wing and controls the telescopic wing unit to move. The invention further discloses a high-speed train based on the telescopic wing device and a control method of the telescopic wing device. During normal operation, necessary lift force is provided for the whole train, so that pressure borne by wheels is reduced, and meanwhile train derailment cannot be caused; and when the high-speed train runs to a special environment with the crosswind effect, the telescopic wing unit is controlled, lift force is only provided on the leeward side of the crosswind effect, lateral force generated by the crosswind effect is resisted, and stable running of the train can be maintained.

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...
