The invention discloses a railway train brake capable of automatically decelerating at a curve. The railway train brake comprises auxiliary wheels, a brake pad and a clamping plate, wherein the two auxiliary wheels are arranged in a bilateral symmetry mode and are fixedly arranged on left and right side surfaces of a rail wheel; a brake cavity with a rightward opening is formed in the train; the rail wheel abuts against the top face of a steel rail; the auxiliary wheels are internally provided with speed reduction cavities which are opened towards the sides away from each other; an arc-shapedplate and a speed reducing ring are arranged in each speed reduction cavity; the arc-shaped plate is in contact with the speed reducing ring, so that the rotating speed of the rail wheel can be reduced. According to the invention, the safety accident problems such as rollover and the like caused by over-high speed can be effectively reduced when a train turns at a railway curve, the train can automatically sense the railway curve and decelerate, the problems of inattention and the like caused by manual operation are reduced, and meanwhile, a hydraulic brake system and an emergency brake deviceare also arranged.
本发明公开了一种可在弯道自动减速的铁路火车制动器,包括辅助轮、刹车片和卡板,所述辅助轮左右对称设有两个,且固设在轨道轮的左右侧面上,火车内设有开口向右的制动腔,所述轨道轮与钢轨的顶面抵接,所述辅助轮内设有向相互远离侧开口的减速腔,所述减速腔内设有弧形板和减速环,所述弧形板和所述减速环接触可减缓所述轨道轮的转动速度,本发明可有效降低火车在铁路弯道转弯时,由于速度过快导致翻车等的安全事故问题,让火车能够自动感应铁路弯道,并加以减速,降低人工操作所产生的注意力不集中等问题,同时还具有液压刹车系统和紧急制动装置。
