The invention discloses a cowcatcher and a railway vehicle, and the cowcatcher comprises a cowcatcher plate which is installed at the bottom of a carriage of the railway vehicle so as to remove obstacles; the energy absorption mechanism is installed at the bottom of the carriage, and the front end of the energy absorption mechanism abuts against the inner side of the barrier removal plate; the protection mechanism is installed between the energy absorption mechanism and the barrier removal plate, and the protection mechanism is constructed to have a protection state for preventing the energy absorption mechanism from deforming and a failure state for breaking under the condition that the protection mechanism bears collision force larger than the bearing force of the protection mechanism; and the energy absorption mechanism is allowed to deform under the action of the collision force so as to further absorb the collision energy. The protection mechanism and the energy absorption mechanism absorb collision energy, and the collision energy absorption effect is improved. When the protection mechanism is in the protection state, the energy absorption mechanism is prevented from deforming, the crashworthiness of the cowcatcher is improved, and loss caused by replacement is reduced.
本发明公开了一种排障器及轨道车辆,其中,排障器包括:排障板,安装于轨道车辆的车厢的底部,以清除障碍物;吸能机构,安装于车厢的底部,吸能机构的前端与排障板的内侧抵接;以及保护机构,安装于吸能机构与排障板之间,保护机构被构造为具有阻止吸能机构发生形变的保护状态,和在受到大于保护机构的承载力的碰撞力的情况下发生断裂的失效状态,以允许吸能机构在碰撞力的作用下发生形变而进一步吸收碰撞能量。保护机构和吸能机构吸收碰撞能量,提升了碰撞吸能效果。保护机构处于保护状态时,阻止吸能机构发生形变,提升了排障器的耐撞性,减少因更换而造成的损耗。
