自制坦克原理课件

 

行动装置

      采用履带行走,就象给坦克铺了一道无限延长的轨道一样,使它能够平稳、迅速、安全地通过各种复杂路况.由于接地面积大,所以增大了坦克在松软、泥泞路面上的通过能力,降低了下陷量.由于履带板上有花纹并能安装履刺,所以在雨、雪、冰或上坡等路面上能牢牢地抓住地面,不会滑转.由于履带接地长度达4~6米,诱导轮中心位置较高,所以通过壕沟、垂壁的能力较强,一般坦克的越壕宽度可达2~3米,可通过1米高的垂直墙.履带还有一个特殊功能,在过河时,采取潜渡,在河底行走;若是浮渡履带可以象螺旋桨一样产生推进力,驱使车辆前进.

 

金属销铰链式和金属橡胶铰链式车辆在其上行进的环形链带装置。

履带是由主动轮驱动、围绕着主动轮、负重轮、诱导轮和托带轮的柔性链环。履带由履带板和履带销等组成。履带销将各履带板连接起来构成履带链环。履带板的两端有孔,与主动轮啮合,中部有诱导齿,用来规正履带,并防止坦克转向或侧倾行驶时履带脱落,在与地面接触的一面有加强防滑筋(简称花纹),以提高履带板的坚固性和履带与地面的附着力。配件图
