阅读说明：本技术 一种抗侧滚扭杆及制备方法 (Anti-side-rolling torsion bar and preparation method thereof ) 是由 吴佩芳 释加才让 刘家鑫 李发长 丁存光 于勇智 肖云健 惠鹏 于 2020-05-11 设计创作，主要内容包括：本发明涉及轨道交通车辆设备技术领域,具体涉及一种抗侧滚扭杆,扭杆轴；两个扭臂,分别与所述扭杆轴的两端部连接；两个垂向连杆,分别与两个所述扭臂的远离所述扭杆轴的端部连接；所述扭杆轴、扭臂、垂向连杆为碳纤维复合材料制成。本发明通过采用碳纤维复合材料制作而成的扭杆轴、扭臂、垂向连杆,使得抗侧滚扭杆在磁场中使用时,不会在抗侧滚扭杆的内部产生感应电动势,因此不会产生涡流效应,进而不会产生热源,可以实现了轨道交通车辆在无接触网供电过程中的零升温,进而保证了轨道交通车辆在运动中的稳定性,降低了安全隐患。(The invention relates to the technical field of rail transit vehicle equipment, in particular to an anti-side-rolling torsion bar, which comprises a torsion bar shaft and a torsion bar shaft; two torque arms respectively connected with two ends of the torque rod shaft; the two vertical connecting rods are respectively connected with the end parts, far away from the torsion rod shaft, of the two torsion arms; the torsion bar shaft, the torsion arm and the vertical connecting rod are made of carbon fiber composite materials. According to the invention, the torsion bar shaft, the torsion arm and the vertical connecting rod are made of the carbon fiber composite material, so that when the anti-side-rolling torsion bar is used in a magnetic field, induced electromotive force cannot be generated in the anti-side-rolling torsion bar, an eddy current effect cannot be generated, a heat source cannot be generated, zero temperature rise of the rail transit vehicle in the power supply process without a contact net can be realized, the stability of the rail transit vehicle in motion is further ensured, and potential safety hazards are reduced.)
