At present, the braking capacity of a subway train adopting friction braking reaches the upper limit, and in order to further enhance the braking capacity of the subway train on the basis, the longitudinal resistance plate design for increasing resistance and reducing speed of the subway train is inspired by an airplane spoiler, and specifically comprises a resistance plate, a front hydraulic rod and a rear hydraulic rod. The multiple resistance plates are longitudinally arranged on the subway roof at unequal intervals, each resistance plate is driven by a front hydraulic rod and a rear hydraulic rod to be opened and closed, and when braking capacity is needed, the resistance plates are driven by the hydraulic rods to be opened; the resistance of the resistance plate is adjusted by adjusting the opening angle and the opening number of the resistance plate. The scheme can serve as a supplement of a traditional braking method, the subway braking capacity is enhanced, and the braking distance is shortened.

    当前利用摩擦制动的地铁列车制动能力已经达到上限,为在此基础上进一步增强地铁列车的制动能力,受飞机扰流板启发,本发明提出了一种用于地铁列车增阻减速的纵向阻力板设计,具体包括阻力板和前后两组液压杆。阻力板为多块,纵向非等间距布置在地铁车顶,每个阻力板分别由前后两组液压杆(分别称为前液压杆和后液压杆)驱动实现打开和收合,当需要制动能力时,阻力板在液压杆的驱动下打开;通过调节阻力板的打开角度和打开数量,调节阻力板的阻力大小。该方案可作为传统制动方法的补充,增强地铁制动能力,缩短制动距离。
