Abstract

A railway vehicle local multi-functional component includes a main body. The main body is an aluminum alloy profile, a reinforcing plate is provided on an outer surface of a bottom plate of the aluminum alloy profile as a vehicle lifting pad, built-in threaded seats are provided on an inner surface of the bottom plate of the aluminum alloy profile as a mounting seat for an anti-yaw damper of a bogie, and a through hole integrally formed with the aluminum alloy profile is provided in the aluminum alloy profile as a cable passage. Multifunction is realized by one structure, thus greatly simplifying the vehicle body local structure, and improving structural strength. A railway vehicle including the local multi-functional component is included.
