The invention discloses a torsion arm lever, a low-noise high-speed train pantograph and a high-speed train, and belongs to the field of high-speed trains. The torsion arm lever comprises a body, reserved connecting sections are arranged at the two ends of the body, a torsion section is arranged in the middle of the body, and the sections of the torsion section and the reserved connecting sections are oval; the long axes of the sections of the torsion section and the reserved connecting section are parallel to the incoming flow direction. According to the low-noise high-speed train pantograph, the upper arm rod and the lower arm rod are of a torsion arm rod structure, the high-speed train comprises the low-noise high-speed train pantograph, the torsion arm rod, the low-noise high-speed train pantograph and the high-speed train are adopted, and the original structure of the high-speed train pantograph is reserved to the maximum extent; and the noise generated in the high-speed running process of the pantograph of the high-speed train is effectively reduced.
本发明公开了一种扭转臂杆、低噪声高速列车受电弓以及高速列车,属于高速列车领域,扭转臂杆包括本体,本体的两端设置有预留连接段,本体中部设置有扭转段,扭转段和预留连接段的截面均为椭圆形,扭转段和预留连接段的截面长轴与来流方向平行。低噪声高速列车受电弓中的上臂杆和下笔杆采用扭转臂杆的结构,高速列车包括低噪声高速列车受电弓,采用上述一种扭转臂杆、低噪声高速列车受电弓以及高速列车,在最大程度上保留高速列车受电弓的原始结构,有效降低高速列车受电弓在高速运行过程产生的噪声。
