The invention relates to a rail car, an anti-rollover device thereof and a rail traffic system, the rail car is movably matched with a rail beam, the rail beam is provided with a stopping part, the anti-rollover device comprises a rotating part used for being rotatably installed on the rail car, and at least part of the rotating part is arranged below the stopping part; and when the rail car inclines, the rotating piece is in rolling contact with the stopping part. When the rail car is impacted by lateral force to roll, the rotating piece is in rolling contact with the stopping part, the rotating piece achieves lateral stopping, meanwhile, the friction resistance, generated by the stopping part, towards the rear portion of the running direction of the anti-rollover device is reduced, and therefore the risk that the anti-rollover device breaks and loses efficacy is reduced, and the service life is long. In addition, the anti-rollover device can be prevented from scratching the stop part, so that the service life of the track beam can be prolonged.

    本公开涉及一种轨道车及其抗侧翻装置、轨道交通系统,所述轨道车可移动地与轨道梁配合,所述轨道梁设置有止挡部,所述抗侧翻装置包括用于可转动地安装在所述轨道车上的转动件,并且所述转动件至少部分设置在所述止挡部的下方,以在所述轨道车倾斜时所述转动件与所述止挡部滚动接触。当轨道车受侧向力冲击发生侧倾时,转动件与止挡部滚动接触,转动件在实现侧向止挡的同时,还降低了止挡部对抗侧翻装置产生的朝运行方向后方的摩擦阻力,从而降低了抗侧翻装置断裂失效的风险,使用寿命长;此外,还可以避免抗侧翻装置刮伤止挡部,因此,可以提高轨道梁的使用寿命。
