Abstract

Masowy, szynowy tłumik hałasu zawierający rezonansowy element stalowy zatopiony w elastycznej otulinie wraz z zasadniczo L — kształtnym sprężystym, profilowanym, elementem mocującym charakteryzuje się tym, że otulina (1) wykonana jest z materiałów elastomerowych, przy czym do jednego z boków otuliny przylega metalowa płytka (3), mającą wybranie (4), natomiast pionowe ramie elementu mocującego ma pierwsze wygięcie osadzone w wybraniu metalowej płytki (4) a ponadto w dolnej części pionowego ramienia elementu mocującego jest drugie wygięcie, zasadniczo u-kształtne, odpowiadające kształtem stopce szyny, natomiast ramie poziome elementu mocującego zakończone jest zasadniczo u-kształtnym zagięciem dostosowanym do nasadzenia go na stopę szyny.A mass rail noise absorber containing a resonant steel element embedded in a flexible casing with a substantially L-shaped, elastic, profiled fastening element characterized by the fact that the casing (1) is made of elastomeric materials, with a metal plate adhering to one of the sides of the casing (3), having a recess (4), while the vertical arm of the fastening element has a first bend embedded in the recess of the metal plate (4) and, moreover, in the lower part of the vertical arm of the fastening element there is a second bend, essentially U-shaped, corresponding in shape to the rail foot, while The horizontal frame of the fastening element ends with a generally U-shaped bend adapted to be placed on the rail foot.
