The invention relates to a critical emergency brake device for a CRH (China Railway Highspeed) train used during rapid running. The device comprises a steel rail, a hydraulic pipe, hydraulic oil, a slope steel pipe, an inner steel pipe, a tension spring, a triangular hydraulic pipe, a circular triangular steel pipe, a fixed spring, a rigid clamping plate and a slope steel rail section. When an accident occurs at the front end of a vehicle, a driver instantly opens the hydraulic pump, the hydraulic oil pumped by the pump instantly pushes hydraulic oil in the full-hydraulic pipe, the vehicle completely flows at the same time, and when flowing, the hydraulic oil extrudes the two sides of the rigid clamping plate through the triangular hydraulic pipe to firmly clamp the steel rail, a wheel stops moving and the inertia impulsive force of the wheel is clamped; when the vehicle runs, the width of the steel rail at the lower end of the vehicle is 20 cm, the wall pressing area at the lower endof the wheel is 19/20, only 1cm area is empty, and the running vehicle cannot vibrate or bump and runs stably.
本发明涉及一种动车快速行驶时临危急刹车装置。包括钢轨、液压管、液压油、斜坡钢管、内钢管、张紧弹簧、三角液压管、圆形三角钢管、固定弹簧、刚性挟板、斜坡钢轨切断面。当车辆行驶时前端发生意外司机瞬间打开液压泵,其泵打出的液压油瞬间推动全液压管中的液压油,车同一时间全流动,液压油流动时经过三角液压管挤住刚性挟板两侧,牢牢挟住钢轨,车轮停止运动,也挟住车轮的惯性冲力;车辆行驶时,其下端的钢轨宽度是20公分,车轮下端压墙面积是19/20,只有一公分面积空虚,行驶的车辆不会发生震荡、颠簸、平稳行驶。
