Zusammenfassung: | The invention relates to the field of rail transit equipment manufacturing, in particular to a symmetric synchronous multi-stage tread balance wing for a high-speed train. The symmetrical synchronous multi-stage tread balance wing of the high-speed train is fixedly mounted on the bottom side of the high-speed train and mainly comprises lift wings, a control unit, a suspension fixing rod, a driving motor and a linkage connecting rod assembly, and the driving motor and the linkage connecting rod assembly are mounted and arranged in inner cavities of the lift wings. The tail length of each stage of lift wing is in a transition mode of step-by-step shortening change from the middle to the two sides, and under linkage driving of the driving motor and the linkage connecting rod assembly, synchronous left-right transverse telescopic movement of the multiple stages of lift wings is achieved. The lift wing device is obvious in lift augmentation effect, controllable in lift force in real time, small in resistance coeff |
