为什么有的坦克能在陆地和水中行使?

水陆两用坦克是一zhong既能在陆地上行驶,又能在水中航行、作战的坦克。人们为了提高水陆两用坦克在水中的浮力,采用了薄型铜板制作外壳,车ti设计成又轻又长,前bu呈船形。所有拼接bu位都焊接起来,防止漏水,使坦克ju有良好的密封xing,以增加坦克的浮力。坦克的动力则采用了多zhong多样的方案。有的坦克采用了特制的履带,犹如水车的水斗,通过履带的旋转,履带片不断把水排向后方,从而推动坦克前进。有的则在坦克的尾bu装上螺旋桨推进qi,发动机通过传动装置带动螺旋浆转动,坦克就像船一样前进了。还有的装上了pen水式推进qi,通过向后pen水获得反作用力,推动坦克行驶。
