The invention discloses an emergency use speed-reducing danger-avoiding device which comprises an arc-shaped plate capable of falling, the arc-shaped plate is arranged at the position of a carriage bottom plate above the front portion of a driving wheel, the bottom face of the arc-shaped plate is an arc-shaped face making contact with the ground and generating sliding friction, and the top face of the arc-shaped plate is a rolling face making contact with wheels and generating rolling friction. And the rolling surface is rotationally connected with at least two stop wheels. According to the structure, during emergency braking, the arc-shaped plate located in front of the driving wheel falls, the bottom surface is subjected to sliding friction speed reduction, the top surface is subjected to rolling friction speed reduction, emergency braking of the vehicle is achieved under the condition that damage to the wheel is minimum, and meanwhile, in the braking process, due to dragging friction motion formed by the arc-shaped plate and the bottom surface, the power of the vehicle is small, and the braking effect is good. And the vehicle is forced to stop suddenly by the braking device of the driven wheel.
本发明公开了紧急使用减速避险装置,包括:可下落的弧形板,该弧形板布置在主动轮的前上方车厢底板位置,该弧形板底面为与地面接触并产生滑动摩擦的弧形面而该弧形板顶面为与车轮接触并产生滚动摩擦的滚动面,该滚动面上转动连接有至少两个止动轮。上述结构在紧急刹车时,位于主动轮前方的弧形板下落,底面滑动摩擦减速,顶面滚动摩擦减速车轮,在对车轮伤害最小的情况下实现车辆的紧急刹车,同时,在刹车过程中,由于弧形板与底面形成拖动的摩擦运动,车辆的动力小时,依靠从动轮的制动装置迫使车辆实现急停。
