The invention discloses an energy absorption structure, a vehicle body and a railway vehicle, the energy absorption structure comprises a conduction part, a first energy absorption device and a second energy absorption device, the conduction part can retreat along with a coupler seat, the first energy absorption device is fixedly connected in front of an airtight wall at the front end of the vehicle body and fixedly connected with the coupler seat, and the second energy absorption device is fixedly connected with the airtight wall. The second energy absorption device is located behind the airtight wall at the front end of the vehicle body and behind the conduction component, so that the conduction component can be cut by the second energy absorption device to absorb collision energy in the retreating process. The energy absorption structure has the large energy absorption capacity, sufficient arrangement space can be reserved for the cowcatcher and the opening and closing mechanism, only the first energy absorption device or the first energy absorption device and the second energy absorption device can be selected to be arranged at the same time, and therefore the use flexibility is high.

    本申请公开一种吸能结构、车体及轨道车辆,所述吸能结构包括传导部件、第一吸能装置和第二吸能装置,所述传导部件能随车钩座一起后退,所述第一吸能装置固定连接在车体前端的气密墙前方且与车钩座固定连接,所述第二吸能装置位于车体前端的气密墙后方且位于所述传导部件后方,使所述传导部件后退过程中能被所述第二吸能装置切削而吸收碰撞能量。该吸能结构有较大的吸能容量,且能给排障器、开闭机构留出充足的布置空间,且能选择仅设置第一吸能装置或者同时设置第一吸能装置和第二吸能装置,因此使用灵活性高。
