VEHICLE (VERSIONS) Russian patent published in 2007 - IPC B62D25/20 B60R13/08 

FIELD: transport engineering.

SUBSTANCE: proposed vehicle, particularly, passenger car, has load-bearing box member of body in spaces of which sealing noise-isolating members in form of acoustic plugs 8 overlapping passage sections of spaces forming limited lengths of hollow load-bearing members are locally arranged. Through drain bypass holes and tubular channels are made in walls of separate limited lengths of sections of hollow members separated formed by end faces of acoustic plugs 8, particularly, in spaces of body floor sills. At least one of drain holes 10 is located in lowermost zone of wall 6 of body sill. Bypass hole 9 in upper wall 7 of body sill is made in form of paired tubular bypass air channels 16 with common dividing partition 17. Inner space of at least one channel is completely or partially filled with high-frequency noise absorber in form of porous noise absorbing material 13 permeable to air.

EFFECT: increased service life of structural members of body and improved acoustic comfort inside car.
