The invention discloses a subway vehicle current collector with two-stage spring damping, and belongs to the technical field of rail transit vehicles. The insulating back plate is connected with the second tooth-shaped plate through the first tooth-shaped plates on the two sides, the other side of the second tooth-shaped plate is connected with the connecting mounting plate, one end of the rubber block is connected with the first rubber block connecting piece, the other end of the rubber block is connected with the second rubber block connecting piece, and the outer circumference of the rubber block is connected with the extension spring. The first rubber block connecting piece is connected with a first spring adjustable connecting block through a shaft, and the first spring adjustable connecting block is connected with a first bolt. The spring assembly comprises the extension spring and the rubber block, the rubber block plays a buffering and damping role, double-side spring damping is achieved when the rubber block acts, compared with a traditional single-side pre-tightening current collector, the phenomenon that the contact face is burnt due to arc discharge is avoided, contact force fluctuation is more stable, current collection is more stable, the service life of the extension spring is prolonged, and the safety performance of the extension spring is improved.
一种两级弹簧减震的地铁车辆受流器,属于轨道交通车辆技术领域。绝缘背板通过两侧的第一齿形板分别与第二齿形板连接,第二齿形板的另一侧与连接安装板连接,橡胶块的一端连接第一橡胶块连接件,橡胶块的另一端连接第二橡胶块连接件,橡胶块的外圆周连接拉伸弹簧,第一橡胶块连接件通过轴与第一弹簧可调节连接块连接,第一弹簧可调节连接块连接第一螺栓。本发明的弹簧组件包括拉伸弹簧和橡胶块,橡胶块,起缓冲减震作用,作用时为双侧弹簧减震,相较于传统单侧预紧的受流器,不会出现拉弧,导致接触面被灼烧的现象,接触力波动更加平稳,受流更加稳定,提高拉伸弹簧的寿命和安全性能。
