具体实施方式
为使本发明实施的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行更加详细的描述。在附图中，自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。所描述的实施例是本发明一部分实施例，而不是全部的实施例。下面通过参考附图描述的实施例是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。下面结合附图对本发明的实施例进行详细说明。
如图1所示，一种可移动重型工程机械的履带系统，包括履带、一个驱动轮5、一个引导轮4、多个支重轮2及2-3个托链轮3；履带由多个顺次连接并形成闭环的履带板1构成；驱动轮5设在履带内，并位于履带后端；引导轮4设在履带内，并位于履带前端；多个支重轮2间隔设在履带内，并位于驱动轮5与引导轮4之间的下部位；多个托链轮3间隔设在履带内，并位于驱动轮5与引导轮4之间的上部位。
如图2所示，履带板1包括支撑部分、牵引部分和主体部分；支撑部分包括滚道面106；牵引部分包括拨齿11及多个外凸的销耳；主体部分两侧轮廓101与相邻履带板中的销耳相配合。
继续参照图2所示，履带板1的滚道面106位于销耳103的上方、拨齿11的两侧，且滚道面106呈圆弧面，两个滚道面106横向交错平行布置。
如图8、图9所示，滚道面106用于与支重轮2的外缘面Ⅰ201配合、与驱动轮5的外缘面Ⅱ501配合、与引导轮4的外缘面Ⅲ401配合；呈圆弧面的滚道面106与呈圆弧面的外缘面Ⅰ201、外缘面Ⅱ501、外缘面Ⅲ401接触面均为椭圆形(即图中S1区域)，该椭圆形(即 图中S1区域)的两端与滚道面106相应两侧均留有未接触区域(即图中P3-P1段，P2-P4段)，以圆弧接触代替边楞接触，大大改善了在不平路面下的接触条件，且能够始终保持良好的接触状态，避免了边缘接触导致的应力集中；另外能够实现履带1对支重轮2提供连续支撑，并大幅度地降低接触应力，减少零部件开裂、剥落等失效问题的发生。
如图2、图5所示，拨齿11设置于履带板1上部的中央位置，用于与驱动轮5的轮齿502啮合传动牵引；拨齿11整体呈底部大、顶部小的四棱锥台形，其中拨齿11的顶面109与啮合面110通过弧面108连接；拨齿11的啮合面110与驱动轮5的驱动面502相配合，实现平移动力的传递。
多个外凸的销耳呈两排间隔分布在履带板1的两侧，并关于拨齿11中心轴180°旋转对称；单侧的多个销耳外凸于主体部分轮廓101，具有用于容纳销轴并将相邻履带板1连接在一起的销孔105，单侧的各销孔105中心重合。履带板1安装时，无需区分方向，避免了人为安装失误。
如图5、图6、图7所示，驱动轮5包括轮体、轮齿502和轮毂509，轮体包括两个外缘面Ⅱ501与多个轮辐506；轮齿502内置于两个外缘面Ⅱ501之间，且轮齿502的顶部不超出外缘面Ⅱ501之外，确保轮齿502仅承受行走驱动力，不受履带系统内部张紧力的作用，优化了轮齿502的受力；轮毂509设有内花键504与浮动密封安装槽503。
轮辐506为中空的双壁形，双侧均开有多个“腰形”的排泥孔Ⅰ508，且与轮齿502间隔布置，两侧轮辐506通过隔板510连接，且隔板510分别与轮齿502中心对齐；轮辐506在对应隔板510的外侧均开有沉槽507。一方面大幅度地减少了驱动轮的整体重量，另一方面能够大大改善铸造工艺性和淬透性，保证结构的机械性能，同时兼有排泥孔的作用，及时排出由履带板卷入的泥土、砂石等。
驱动轮5的外缘面Ⅱ501的圆弧半径数值与滚道面106圆弧数值大小相等或略小些，以确保整机在斜面上作业或行走时接触状态保持良好；
驱动轮5的导向面505为斜面，与拨齿11的侧面107配合，确保履带板1与驱动轮5顺利进入啮合位置。
如图3所示，支重轮2为哑铃形，支重轮2的两个外缘面Ⅰ201之间的中部空腔Ⅰ202可容纳履带板1的拨齿11通过；外缘面Ⅰ201的圆弧半径数值与驱动轮5的外缘面Ⅱ501的圆弧半径数值相等。
如图4所示，引导轮4的两个外缘面Ⅲ401之间的中部空腔Ⅱ402可容纳履带板1的拨齿11通过；外缘面Ⅲ401的圆弧半径数值与驱动轮5的外缘面Ⅱ501的圆弧半径数值相等。
如图1所示，托链轮3为哑铃形，托链轮3的两个外缘面Ⅳ之间的中部空腔Ⅲ可容纳履带板1的拨齿11通过。
如图1、图2所示，主体部分内部设有多个空腔，相邻的两个空腔之间通过孔联通，并且左侧和右侧的空腔均通过窗口111与外界联通；在滚道面106外侧的主体部分上设有排泥孔Ⅱ112，且该排泥孔Ⅱ112与主体部分内的空腔相连通。在行进过程中待履带顶部朝下时，可排出进入内部腔体中的泥、碎石、雨水等，同时在装配过程中，该排泥孔Ⅱ112亦可作为起吊孔使用。
由上述结构可见，本发明大幅度地优化了履带板与支重轮、引导轮、托链轮的滚道面接触条件，履带可向支重轮提供连续支撑，接触应力更小，整体铸造工艺性更优，且总重量更轻，在保证可靠性的情况下有助于提高整机的灵活性和机动性，尤其适用于重型工程机械。
本发明还提供一种工程车辆，具有上述的可移动重型工程机械的履带系统。该工程车辆包括挖掘机、起重机，旋挖钻机等工程机械车。
最后应当说明的是:以上实施例仅用以说明本发明的技术方案而非对其限制；尽管参照较佳实施例对本发明进行了详细的说明，所属领域的普通技术人员应当理解：依然可以对本发明的具体实施方式进行修改或者对部分技术特征进行等同替换；而不脱离本发明技术方案的精神，其均应涵盖在本发明请求保护的技术方案范围当中。
