Embodiment Construction
[0020] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0021] Such as Figure 1 to Figure 3 As shown, the flank lift control mechanism of the high-speed rail transit train includes a base 1, a wing plate 2, a wing plate rotating assembly 3 that is connected to the wing plate 2 and drives the wing plate 2 to rotate, and is connected to the wing plate rotating assembly 3 and Flange telescopic assembly 4 between bases 1 . The control mechanism is respectively arranged at the middle position of the head car and the middle position of the tail car of the train. The wing plate 2 is arranged on the train car wall, and the wing plate telescopic assembly 4 is used to perform telescopic operation on the wing plate 2. When it is in a non-working state, the wing plate 2 shrinks to...

The invention discloses a high-speed rail transit train side wing lift force control mechanism, which includes a base, a wing plate, a wing plate rotating assembly which is connected to the wing plateand drives the wing plate to rotate, and a wing plate telescopic assembly connected between the wing plate rotating assembly and the base. The wing plate rotating assembly includes a swinging controlbox and a driving assembly located in the swinging control box, and the driving assembly is connected with the wing plate; and the wing plate telescopic assembly includes a bearing rod and a telescopic piece which are connected between the base and the swinging control box correspondingly, and the end, away from the swinging control box, of the bearing rod extends into the base. According to thehigh-speed rail transit train side wing lift force control mechanism, the structure is simple, use is reliable and convenient, expansion and rotation of the wing plate are realized through the wing plate telescopic assembly and the wing plate rotating assembly, and by rotating the wing plate in different directions, lift force of a head car and a tail car is adjusted to maintain the stability of the whole train operation.
Description
technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a flank lift control mechanism for high-speed rail transit trains. Background technique [0002] For high-speed rail transit trains, when the high-speed train is running, the aerodynamic lift force received by the head car is downward, which increases the wear between the train wheels and rails, and reduces the service life of the train wheels and tracks to a certain extent; while the tail car The received aerodynamic lift is upward, which makes the train "float" a bit during operation, reduces the stability of the tail car operation, and reduces the safety of the train operation. Contents of the invention [0003] The purpose of the present invention is to provide a high-speed rail transit train flank lift control mechanism to solve the problems of low stability and easy wear of train wheels and rails in the operation of existing high-speed trains. [0004] The technica...
