TUBE-BUFFER FOR RAILWAY VEHICLES

摘要

Disclosed herein is a tube buffer for railway vehicles, installed to the fore of a railway vehicle to absorb impact energy generated in the event of a collision of the railway vehicle. The die of the tube buffer expands a tube by impact energy, and simultaneously the blades of the die cut the expanded tube, so that the efficiency of absorbing impact energy is excellent and a small installation space is required. Further, a stabilizer provided on the tube buffer absorbs stage conversion impact generated when an impact energy absorbing stage is converted into a subsequent impact energy absorbing stage while the tube buffer absorbs impact energy in several stages, thus allowing the impact energy to be smoothly absorbed, therefore protecting drivers and passengers in case of an accident, and preventing a railway vehicle structure from being broken or damaged.
