FIELD: transport engineering; vehicles with frame design of load-baring body. SUBSTANCE: in proposed vehicle load-bearing skeleton of body has hollow load-bearing members, such as sidemembers, crosses and pillars whose tunnels, at least partially, are filled with noise-and-vibration damping material. Novelty is that members are made in form of solid bars of metal porous fiber material permeable to gas and slacklessly installed in tunnels of load-bearing members. Geometric shape of bars corresponds to trajectory of inner space of tunnel accommodating tyre bar. Proposed device can find application in automobiles which require improved acoustic aerodynamic characteristics. EFFECT: improved riding comfort, passive safety, strength and increased service life. 3 dwgo |
