    • A damper for a train coupler is shown, comprising a hydraulic balancing chamber (115) defined in an annular space between a piston (101) and a housing (102) in which the piston is movably received, wherein the balancing chamber is in flow communication with a hydraulic high-pressure chamber (103) via inlet and outlet bores (116; 130) formed through a slip-ring (117) that journals the piston in the housing. A portion (129) of the piston is shielded in a buffer chamber (128) formed in the annular space between the piston and the housing, in axial alignment with the balancing chamber.
    • 示出了用于列车车钩的阻尼器,其包括限定在活塞(101)和壳体(102)之间的环形空间中的液压平衡腔室(115),活塞可移动地容纳在该壳体中,其中平衡腔室流体连通 与经由将活塞卡在壳体中的滑环(117)形成的入口孔和出口孔(116; 130)形成液压高压室(103)。 活塞的一部分(129)在形成于活塞与壳体之间的环形空间中的缓冲室(128)中与平衡室轴向对齐地被屏蔽。

    • An energy absorption device (3) and method is disclosed for absorption of energy that is released upon impact between two objects in relative motion, wherein an exceptional load applied to any of the two objects results in acceleration of said object relative to the other object, and wherein for retardation of said acceleration energy is absorbed in the process of deformation of an element or elements which are put under stress from the objects upon impact. The process of deformation comprises a controlled diameter reduction during a forced elongation of a semi-solid or solid deformation bolt (4) made of cold-forming material in the direction of force (FX) generated in said acceleration.
    • 公开了一种能量吸收装置(3)和方法,用于吸收在相对运动中的两个物体之间的冲击时释放的能量,其中施加到两个物体中的任一个的异常负载导致所述物体相对于另一物体的加速, 并且其中对于所述加速能量的延迟在被冲击时从物体施加应力的元件的变形过程中被吸收。 变形过程包括在由冷成形材料制成的半固体或固体变形螺栓(4)在所述加速度中产生的力(FX)方向的强制伸长期间的受控直径减小。
