Definitions

• Elastic damping device (options).
• the invention relates to mechanical engineering, in particular, to devices for elastic perception of loads and damping vibrations.
• a disadvantage of the known device is the irrational use of the volume of the elastic element, due to the structural features of the core and the housing.
• the technical result, to which the invention is directed, is to increase the efficiency of an elastic damping device by including in the work a large part of the volume of the elastic element and equalizing the loads arising in it.
• the technical result is achieved in that in an elastic-damping device comprising a composite housing with a thrust protrusion and a supporting surface for an annular conical elastic-damping element with an oval section, covering the core forming the supporting surface of the housing, at least for part of its length made curvilinear and can be formed by at least one circular arc.
• an elastic-damping device comprising a housing with a thrust protrusion for an annular cone-shaped elastic damping element with an oval cross-section covering the core, the core is made with a thrust protrusion mating with the thrust surface of the core to form a deformation chamber of the elastic damping element.
• FIG. l shows an elastic damping device according to the first embodiment
• FIG. 2 shows an elastic damping device according to the second embodiment.
• the elastic-damping device comprises a housing consisting of a cylinder 1 with an internal thrust protrusion 2 at one end thereof and at least one cylindrical groove 3 and connected, for example, by means of a thread 4, which can be made, for example, in the form of a cup.
• a recess 5 and a threaded hole 6 for the fastening element 7 of the shock absorber to the supporting structure 8 of the vehicle are made about the base.
• a core 9 on the protruding part of the housing 10 of which a push-in remote element 11 is provided, fixed or made for one made with it (for simplicity, not shown in the drawing) and an annular conical elastic element 12, in cross section having an oval shape.
• the elastic element with an interference fit covers the core 9 and is in contact with the base 4, the pressure remote element and the protrusion 2 of the cylinder.
• the core is connected to the depreciable object 13 by means of a threaded rod (bolt) 14.
• Elastically damping devices operate as follows.
• the pressure-sensitive remote element 11 Under the action of a vertical load, the pressure-sensitive remote element 11 will act on the elastic element 12, which, deforming, will fill the volumes in the housing 8 and the core 9. As a result, most of the thermal energy will be extinguished and transformed into the environment. Under the action of horizontal force on the shock absorber, the core 9 together with the elastic element 12 will move, and the elastic element will deform in the direction of the force. The squeezed material of the elastic element 12 will fill the appropriate volumes in the body and core, transforms the energy of mechanical action into its heat, which will be immediately absorbed by the air. After removing the loads, the elastic element 12 will restore its original shape and location of the elements of the site.
• a feature of the node according to the first embodiment is the implementation of the supporting surface 15 of the base 4 of the housing along a curved generatrix formed by at least one circular arc.
• the implementation of the supporting surface 15 is curved, allows you to realize the rolling effect of the lower base of the elastic element in the process of its deformation and to prevent the occurrence of local increased stresses in the volume of the elastic element.
• the execution of the surface 15 is curved, also allows you to increase the distance between the specified surface and the core 9, which contributes to a more uniform deformation of the elastic element, because eliminates the separation of the lateral surface of the elastic element from the bottom of the core.
• a feature of the assembly according to the second embodiment is the use, instead of a bell-shaped core, of a core with a thrust protrusion 16, which allows creating a chamber on the side of the core for deformation of the elastic element and reducing the number of grooves in the cylinder or eliminating them completely.
