VEHICLE (VERSION) 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 member 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. According to one of possible design versions, vehicle contains load-bearing box members of body inside spaces of which sealing sound-isolating members in form of acoustic stoppers are locally arranged which close through sections of spaces with formation of limited lengths of hollow load-members. Peculiarity is that through drain and bypass holes and tubular channels are made in walls o some limited lengths of acoustic stoppers, particularly, in spaces of sills of body flow adjacent to space of passenger salon and external medium surrounding vehicle body. At least one of drain holes is arranged in lowermost zone of wall of body sill, and bypass hole in upper walls of body sill is made in from of tubular bypass air channel. Three independent design versions of vehicle are proposed whose practical use provides increase of service life of body structure members.

EFFECT: improved acoustic comfort in vehicle.
