VEHICLE Russian patent published in 2007 - IPC B62D25/20 G10K11/16 

FIELD: mechanical engineering; transport engineering.

SUBSTANCE: proposed invention is construction of wheeled vehicle, particularly, passenger car whose load-bearing members of body are made in form of box hollow sections - sills, reinforcement members, posts, which are furnished with local sealing sound-isolating members overlapping air sound transmitting through sections of hollow load-bearing members in preset zones. Vehicle, particularly, passenger car, contains load-bearing box members of body accommodating locally arranged sealing sound-isolating members in form of acoustic stoppers closing through sections of spaces with formation of limited lengths of hollow load-bearing members in form of final lengths of acoustic waveguides. Through drain holes and tubular bypass branch pipes are made in walls of separate limited lengths of sections of hollow members separated/formed by end faces of acoustic stoppers, particularly, in spaces of sills of body floor adjacent to space of passenger saloon and external medium surrounding vehicle body. Axes of drain holes and/or open inlet cuts of tubular bypass branch pipes are arranged in zones from end face walls of box hollow space at a distance multiple of 1/4L where L is lengths of space limited by end faces of acoustic stoppers.

EFFECT: improved acoustic comfort in passenger saloon and cab of car.
