TRANSPORT FACILITY Russian patent published in 2015 - IPC B62D25/20 B60R13/06 

FIELD: transport.

SUBSTANCE: invention relates to transport engineering. The transport facility contains strength box-type body elements inside which sealing sound insulating elements in the form of stopper plugs are locally placed. The stopper plugs cover cross-sections of cavities with creation of limited lengths of hollow strength elements in the form of finite lengths of acoustic waveguides. In the walls of strength elements adjacent to passenger compartment space and external medium surrounding transport facility body, through drainage holes and tubular bypass fitting pipes. In the cavity of tubular bypass fitting pipe, sound eliminator is installed. The sound eliminator is made in the form of plug-in element of porous sound-absorbing air-permeable material.

EFFECT: higher acoustic comfort in transport facility.
