Central coupler suitable for collision energy management system and locomotive with same

The invention relates to the technical field of railway locomotives, and provides a central coupler suitable for a collision energy management system and a locomotive with the same. The central coupler suitable for the collision energy management system comprises a coupler buffering device, a coupler box main body and a slave plate seat. The coupler buffering device comprises a buffer, the couplerbox main body is mounted on a chassis of the locomotive, the coupler buffering device is connected with the slave plate seat, and the slave plate seat is connected with the coupler box main body. When the impact force borne by the coupler buffering device is larger than the connecting force between the slave plate seat and the coupler box main body, the slave plate seat is separated from the coupler box main body, and the coupler buffering device drives the slave plate seat to move relative to the coupler box main body. The collision resistance and safety of the locomotive can be improved through the coupler bufferin
