    • An energy absorbing coupler for railway vehicles includes a coupler anchor, a coupler mechanism supported to the coupler anchor by a deformation tube and draft gear element, and a plurality of energy absorbing devices associated with the coupler anchor. The energy absorbing devices each include two mating components in frictional engagement with one another. Sliding movement between contacting surfaces of the two components occurs when energy is applied to the coupler mechanism, thereby creating friction and dissipating the applied energy at least in part in the form of heat. The two mating components may include a male part, such as a mounting bolt, in mating engagement within a female part, such as a collar. An inside diameter of the collar may be slightly smaller than an outside diameter of the mounting bolt to create a press-fit engagement.
    • 用于轨道车辆的能量吸收耦合器包括耦合器锚,通过变形管和牵引齿轮元件支撑到耦合器锚的耦合器机构,以及与耦合器锚固件相关联的多个能量吸收装置。 能量吸收装置各自包括彼此摩擦接合的两个配合部件。 当能量施加到耦合器机构时,两个部件的接触表面之间的滑动运动发生,至少部分地以热的形式产生摩擦和耗散施加的能量。 两个配合部件可以包括凸形部件,例如安装螺栓,其配合接合在阴部件(例如轴环)内。 套环的内径可以略小于安装螺栓的外径,以产生压配合。
