Abstract

1. Демпфер, содержащий корпус и размещенный в нем поршень, отличающийся тем, что корпус выполнен в виде цилиндра с днищем, в котором расположен поршень, выполненный в виде стакана с, параллельными между собой и соосными корпусу, верхним и нижним буртиками, которые расположены относительно внутренней поверхности корпуса с зазором, а между буртиками расположен фрикционный материал, а в нижнюю поверхность поршня упирается пружина, расположенная между поршнем и днищем корпуса, причем полость между поршнем и днищем корпуса, в которой расположена пружина, заполнена фрикционным материалом с более высоким коэффициентом трения, а верхняя поверхность верхнего буртика поршня упирается в упругое кольцо, соединенное со стопорным элементом, выполненным, например, в виде стопорного кольца, фиксируемого в канавке внутренней поверхности цилиндра корпуса, при этом стопорный элемент через упругое кольцо контактирует с верхней поверхностью верхнего буртика поршня, удерживая его в исходном состоянии.2. Демпфер по п. 1, отличающийся тем, что в качестве фрикционного материала, расположенного между буртиками поршня, в зависимости от требуемого коэффициента трения, используется металлическая стружка, пластмассовые или металлические шарики.3. Демпфер по п. 1, отличающийся тем, что в качестве фрикционного материала с более высоким коэффициентом трения, расположенного в полости между поршнем и днищем корпуса, в которой расположена пружина, используется, например, песок, шарики из полиуретана, элементы сетчатой структуры, плотность элементов сетчатой структуры находится в оптимальном интервале величин 1,2…2,0 г/см, причем материал проволоки упругих сетчатых1. A damper comprising a housing and a piston disposed therein, characterized in that the housing is made in the form of a cylinder with a bottom, in which a piston is arranged in the form of a cup with, parallel to each other and coaxial to the housing, upper and lower flanges, which are located relative to the internal surface of the housing with a gap, and friction material is located between the shoulders, and a spring located between the piston and the bottom of the housing abuts against the lower surface of the piston, the cavity between the piston and the bottom of the housing in which and the spring is filled with friction material with a higher coefficient of friction, and the upper surface of the upper shoulder of the piston abuts against an elastic ring connected to a locking element made, for example, in the form of a locking ring fixed in the groove of the inner surface of the cylinder of the housing, while the locking element through the elastic ring is in contact with the upper surface of the upper shoulder of the piston, holding it in its original state. 2. The damper according to claim 1, characterized in that metal chips, plastic or metal balls are used as the friction material located between the piston shoulders, depending on the required coefficient of friction. The damper according to claim 1, characterized in that, for example, sand, polyurethane balls, mesh elements, density of elements are used as a friction material with a higher coefficient of friction located in the cavity between the piston and the bottom of the housing in which the spring is located mesh structure is in the optimal range of values of 1.2 ... 2.0 g / cm, and the material of the wire elastic mesh
