The invention relates to a railway vehicle buffering device and a coupler buffering system, and belongs to the technical field of railway vehicle buffering. The railway vehicle buffering device comprises a shell, a traction rod, a sleeve, an elastic piece and a conversion plate; wherein the shell is hollow and one end of the shell is open; the traction rod is mounted at the opening of the shell and is axially connected with the shell in a sliding manner; the first end of the traction rod extends into the shell, and a first containing space is formed. The sleeve is arranged between the traction rod and the shell, is clamped with the first end of the traction rod and moves along with the traction rod when the traction rod is pulled; the elastic piece is installed in the first containing space and is coaxial with the traction rod. And the conversion plate is arranged at the end part of the first end of the traction rod and is tightly matched with the traction rod and the elastic piece. According to the railway vehicle buffering device, the installation gap can be eliminated, abnormal sound, impact and abrasion caused by the gap are avoided, the safety of the railway vehicle buffering device is improved, and the service life of the railway vehicle buffering device is prolonged.
