Description

用于轨道车辆的内拉断式缓冲装置 技术领域
本发明涉及一种铁道车辆缓冲装置，尤其是包括与车钩连接的缓冲器、与车体连接的安装座以及连接缓冲器与安装座的旋转轴的具有过载保护功能的缓冲装置。
背景技术
钩缓装置是铁道车辆基本部件之一，起到快速连接和分解铁道车辆、传递列车牵引力、提高车辆安全性、改善车辆舒适性能的作用。
钩缓装置主要由车钩连挂装置、压溃装置、缓冲装置和过载保护装置组成。车钩连挂装置起到连挂和分解列车车辆的功能；压溃装置在紧急情况下起到保护车体及乘客安全的作用；缓冲装置作为钩缓装置改善纵向冲动性能，提高车辆安全舒适性的装置；过载保护装置能够在轨道车辆受到极大纵向冲击时，使钩缓装置与车辆分离，进而让车辆上的其他能量吸收装置发挥功效。缓冲装置作为钩缓装置中重要的能量吸收装置，主要参与轨道车辆正常运行过程中的纵向能量吸收。橡胶缓冲器内部装有牵引杆和橡胶弹性元件，当牵引杆承受车辆纵向载荷时，会引起弹性元件的变形，进而完成缓解冲击、吸收能量的作用。过载保护装置一般直接将钩缓装置与轨道车辆车体联结在一起，并通过自身的分解使上述二者分离。
目前，常见的轨道车辆缓冲装置与过载保护装置是分离的，安装接口与常见车体不同，一般需要用一块带有两种接口尺寸的金属板进行转换。因此二者若要安装在现有轨道车辆上就需要对车辆结构进行更改，适应现有安装接口、满足钩缓装置与车辆分离后的退行空间等等。
 发明内容
本发明的目的在于提供一种将轨道车辆缓冲装置与过载保护装置集成在一起，不需要配备专门接口转换装置即可与现有车辆进行装配的用于轨道车辆的内拉断式缓冲装置。
本发明的技术方案为：一种用于轨道车辆的内拉断式缓冲装置，包括与车钩连接的缓冲器、与车体连接的安装座以及连接缓冲器与安装座的旋转轴；所述的旋转轴表面与缓冲器壳体的上下表面均设置有台阶结构，二者相互配合传递纵向牵引力，所述的台阶结构之间设置有拉断式过载保护元件，并将二者连接在一起。
优选的是：所述的拉断式过载保护元件在水平方向连接台阶结构。
优选的是：所述的拉断式过载保护元件设置为可断裂的元件。
优选的是：所述的可断裂的元件设置为拉断螺栓。
优选的是：所述的缓冲器包括缓冲器壳体、位于壳体内的牵引杆以及弹性元件，牵引杆伸出壳体并与车钩连接。
优选的是：所述的牵引杆上设置有凸起隔断，弹性元件位于凸起隔断之间。
本发明的有益效果为：内拉断式缓冲装置的安装接口与现行轨道车辆钩缓装置安装接口完全一致，不需要类似安装转接板的接口转换设备，在增加过载保护功能的同时不需要对轨道车辆车体结构进行更改，降低了技术实现的难度。并且，拉断式的过载保护元件相对已有的剪切式的元件来说，过载触发更稳定，不易出现失效。此外，由于过载保护拉断动作发生在缓冲装置内部，因此钩缓装置向后方退行所需要的空间大大减小，车辆底架的设计难度因此降低，车体底架的强度由此也得以增加。
 附图说明
图1为本实用新型具体实施例的示意图；
图2为本实用新型具体实施例的剖视结构示意图；
图3为本实用新型具体实施例的剖视结构示意图；
图4为本实用新型具体实施例的过载保护动作示意图。
 具体实施方式
下面结合附图说明本发明的具体实施方式：
一种用于轨道车辆的内拉断式缓冲装置，包括与车钩连接的缓冲器、与车体连接的安装座4以及连接缓冲器与安装座4的旋转轴3；所述的旋转轴3表面与缓冲器壳体1的上下表面均设置有台阶结构，二者相互配合传递纵向牵引力，所述的台阶结构之间设置有拉断式过载保护元件，并将二者连接在一起。所述的拉断式过载保护元件在水平方向连接台阶结构。所述的拉断式过载保护元件设置为可断裂的元件。所述的可断裂的元件设置为拉断螺栓6。所述的缓冲器包括缓冲器壳体1、位于壳体内的牵引杆2以及弹性元件5，牵引杆2伸出壳体1并与车钩连接。所述的牵引杆2上设置有凸起隔断，弹性元件5位于凸起隔断之间。
缓冲器壳体1分为上下两部分，其内部安装有牵引杆2和弹性元件5，上述二者被上下两部分缓冲器壳体1夹紧，使得弹性元件5在安装后具有一定预紧力，能够传递、吸收由牵引杆2带来的轨道车辆纵向载荷。缓冲器壳体1外侧设计有凸台结构，可以与同样具有凸台结构的旋转轴3相配合，两部分缓冲器壳体1分别与旋转轴3配合到位后通过拉断式过载保护元件连接、紧固。轨道车辆的牵引载荷不会传递给该元件，过大的牵引载荷也不会导致该元件的断裂。但轨道车辆的压缩载荷会传递至该元件，且当载荷超过预先设定值时，该元件会断裂。缓冲器壳体1与旋转轴3通过拉断式过载保护元件连接后，二者固定、不会相对转动，但旋转轴3可以在安装座4的圆孔内自由转动。安装座4上下都设置有安装圆孔，可以安装旋转轴3，安装座4还设置安装螺栓接口，能够通过螺栓与轨道车辆车体连接。
如图4所示，牵引杆2可以传递轨道车辆的纵向载荷，通过内部弹性元件5的变形来吸收能量。当牵引杆2承受的载荷超过拉断式过载保护元件预先的设定值时，拉断式过载保护元件会产生断裂，从而使缓冲器壳体1与旋转轴3之间的连接断开，进而让牵引杆2等零件向轨道车辆后方运动。上述过载保护动作的发生可以使轨道车辆在受到严重的意外撞击时，通过钩缓装置自身断裂、向后退行，从而使车辆的其他能量吸收装置继续发挥作用，保护车辆自身不受到损伤。
