(5) ЗАДНИЙ ОБТЕКАТЕЛЬ АВТОПОЕЗДА(5) REAR HEAT TRAIL
II
Изобретение относитс к транспортным средствам, преимущественно к автопоездам , грузовым автомобил м и автобусам, двигающимс с высокими скорост ми, и может служит дл уменьшени аэродинамического сопротивлени .The invention relates to vehicles, mainly road trains, trucks and buses traveling at high speeds, and can serve to reduce aerodynamic drag.
Наиболее близким к изобретению техническим решением вл етс - задний обтекатель автопоезда, содержащий закрепленные на задней стенке полуприцепа плоские элементы с аэродинамическими поверхност ми 1 .The closest technical solution to the invention is the rear fairing of an articulated train containing flat elements fixed to the rear wall of the semi-trailer with aerodynamic surfaces 1.
Указанные элементы расположены параллельно набегающему потоку на некотором рассто нии от задней стенки кузова полуприцепа. При установке данного обтекател на задней стенке кузова полуприцепа встречный поток частично направл етс через зазор между задней кромкой обтекател и стенкой кузова, а затем смешиваетс с воздухом, обтекающим его с.внешних сторон, что преп тствует образованию зон повышенной плотности и снижает аэродинамическое сопротив .ление автопоезда на 6-8. Указанный обтекатель обладает более простой конструкцией, но в остальном ине,ет следующие недостатки: наличие зазора между внутренней поверхностью обтекател и наружной стенкой полуприцепа приводит к забиванию его гр зью и атмосферными осадками: приThese elements are located parallel to the incident flow at some distance from the rear wall of the semi-trailer body. When installing this fairing on the rear wall of the semi-trailer body, the counter flow is partially directed through the gap between the rear edge of the fairing and the body wall, and then mixed with air flowing around its outer sides, which prevents the formation of high density zones and reduces aerodynamic resistance. road trains at 6-8. This fairing has a simpler design, but otherwise it does not have the following disadvantages: the presence of a gap between the inner surface of the fairing and the outer wall of the semi-trailer leads to clogging it with dirt and atmospheric precipitation:
