Claims (6)

1. A package of annular springs with a damper, consisting of interconnected external and internal annular elastic conical disks, characterized in that it consists of a set comprising at least two pairs, opposed to and interconnected by large bases of annular elastic conical disks so that in the joint of each pair an inner toroidal surface of radius R is formed, and in the joint of a set of these pairs on the smaller base of the annular elastic conical disks an external toroidal in shape a surface of radius R, wherein each of the annular elastic conical disks has a lateral conical surface with spherical segments of radius R located respectively at the larger base of the truncated cone and the smaller base of the truncated cone of each of the disks, and the spherical segments are made together with the conical surfaces of each of the disks and directed in different directions from the generatrix of the conical surface, i.e. one spherical segment of each disk is directed inside the conical surface and the other outward, while the number of pairs of disks in the set of such springs may be different depending on the stiffness and size of the spring travel, and the set of ring springs, consisting of pairs of annular elastic conical disks, in a cylindrical body, the lower part of which is rigidly connected to a base having a centering cylindrical flange, which includes a smaller base of one of a pair of annular elastic conical disks, and in the upper part the whisker is movable, with a gap there is a lid with a centering cylindrical collar, on which the smaller base of the other pair of a set of annular elastic conical disks is centered, while a groove is made on the cylindrical surface of the casing to reduce its radial stiffness, while large bases are opposite and connected between by itself, the annular elastic conical disks of each pair enter with a gap into the housing, based on its inner cylindrical surface, on each of the annular elastic cones x disks are made of at least three radial grooves directed from the smaller base of the truncated cone to the larger base, with each of the radial grooves ending with a hole, to relieve stresses, grease is introduced into the cavity between the cover and the adjacent annular elastic conical disk, for example solid oil, and the cavity between the base and the adjacent annular elastic conical disk is filled with an elastomer, for example polyurethane, while the cavities formed between pairs of adjacent annular elastic conical disks are filled they are molded with crumb from a vibration-damping material, for example, “Agate” type, and the centering cylindrical collar, the lower part of which is rigidly connected to the base, and which includes the smaller base of one of a pair of annular elastic conical disks, is made of sintered friction material based on iron containing the following components in their ratio, wt. %: copper  5.0 ÷ 7.0; graphite  4.0 ÷ 5.0; asbestos  2.0 ÷ 3.0; silicon carbide  4.0 ÷ 6.0; iron sulfate 5.0 ÷ 6.0; cobalt  3.0 ÷ 4.0; phosphoric slag  3.0 ÷ 4.0; iron rest. 2. A package of annular springs with a damper according to claim 1, characterized in that the centering cylindrical flange, the lower part of which is rigidly connected to the base, and which includes a smaller base of one of a pair of annular elastic conical disks, is made of sintered friction material based on copper containing zinc, iron, lead, graphite, vermiculite, copper, chromium, antimony and silicon, in the following ratio, wt. %:  zinc 6.0 ÷ 8.0;  iron 0.1 ÷ 0.2;  lead 2.0 ÷ 4.0;  graphite 3.0 ÷ 7.0;  vermiculite  8.0 ÷ 12.0; chromium 4.0 ÷ 6.0; antimony 0.05 ÷ 0.1;  silicon 2.0 ÷ 3.0; copper rest.
