Abstract

A cushioning device consists of a cylindrical body closed from one side by a bottom, and pressed by a thrust plate of an elastic support unit. The support unit is partially located inside the cylindrical body of the device with possibility of displacement relative thereto and it is made in the form of an elastomeric shock-absorber. The shock-absorber consists of a cylindrical body filled with an elastomer, and a rod, which by one end rests on the bottom of device body, while on the other it comprises a piston that separates the working chamber of the shock absorber into two cavities with possibility of flowing elastomeric mass from one chamber to another through a calibrated gap between the lateral cylindrical surface of the piston and the inner surface of the body. The thrust plate by bolts and mounting brackets is connected to the device body with possibility of displacement relative thereto.

Description

deformations that inevitably occur when the piston and the inner surface of the housing are subjected to high shock loads. to this thrust plate with the help of bolts and mounting

The closest in essence and effective bars are connected to the body of the device with the power that is achieved, and which is accepted by the duration of movement relative to it. type, there is an absorbing device for railway transport. plate elastic support node of the hosyl characteristics of the proposed sinker in the form of an elastomer sleeve and a hollow body of the floating device without reducing the resource of its parts See. stalemate. of Russia Me 2373092 of class Vb109/06, operation, as during impact compression published on November 20, 2009 in Byul. Mo 321. of the specified energy absorption shock absorber

The main disadvantage of the known technical is that the energy of the impact is absorbed by the non-tomer material, that is, without the involvement of work, only due to the accumulation of internal energy of frictional forces that cause wear. In addition, when compressing the elastic elastomer sleeve, and for the proposed shock absorber due to the metal friction of the outer cylindrical surface of the housing, it has the necessary rigidity, has a simple last against the walls of the housing. This leads to a construction that is technological in the manufacture and maintenance of contacting working surfaces, and in the baking, which allows to simplify the assembly of the absorbent and to reduce the resource of the operation of the well-known cleaning apparatus and significantly increase its repair and absorption apparatus. suitability At the same time, it is constructive

The indicated problem is partially solved due to the modification of the thrust plate, which is necessary for the implementation of the presence of an elastomer sleeve on the surfaces and the proposed technical solution in the composition of the plunger, grooves with solid lubricant, but this casting device does not in any way lead to a solution that significantly complicates the design and maintenance. to a decrease in the functionality of the device or the absorption apparatus, which is the second disadvantage of its structure. by means of a known technical solution. Thus, the entire set of essential features

The third shortcoming of the known absorbent apparatus is the imperfection of the design of the elastic support apparatus of the modified structure, which, in particular, consists in the absence of a technical result. stiffness of the elastomer bushing, which does not allow the further essence of the useful model is explained to increase the amount of absorbed and scattered energy. together with illustrative material on which

The fourth disadvantage of the known absorber is the following: Fig. 1 - a general view of the device is the necessity of mandatory compliance with the proposed absorber in a partial longitudinal section when installing the plunger and elastomer in the body; Fig. 2 - a side view of the bushings of the recommended seating gap (the proposed absorbing device in partial revelation within the stated limits of 0.05-0.2 mm) for the longitudinal section. ensuring reliable operation of the device. The proposed absorbing device contains a limiting condition that makes it difficult to assemble the absorbing device - a hollow cylindrical body 1, closed on one side of the device and reducing its repairability, on the other side by the bottom 2. Partly inside the cylinder - because compliance with the specified gap between the partial body 1 with the possibility of moving from - in worn and new parts, there may be an elastomeric blematic. shock absorber 3, which consists of a cylindrical

The basis of the useful model is the task of the body 4, filled with elastomer, and the rod 5. to ensure the completeness of the power characteristics. At one end of the rod 5, there is a piston 6, a tic of the absorbing device with a simultaneous simplification, which separates the working chamber by the cylindrical body of its design and increasing the resource exa 4 into two chambers 7 and 8 with the possibility of pluation overflow due to the introduction of new elements of elastomeric mass from one chamber to another through designs and modifications already known by the calibrated gap 9 between the side surface of the corresponding structural improvements. shaft 6 and the inner surface of the cylindrical

The solution to the problem is achieved by the body 4. The other end of the rod 5 rests on what is in the absorbing apparatus, which consists of the bottom 2 of the cylindrical body 1. The elastomeric shock absorber from the cylindrical body, closed on one side, is pressed by the thrust plate 10, the bottom, and pressed by the thrust plate elastic which with the help of bolts 11 and mounting strips 12 of the support node, according to the useful model, is connected to the body of the device with the possibility that the support node is located partially inside the cell relative to it. of the body of the apparatus with the possibility of moving the proposed absorbing apparatus works relative to it and is designed as follows. of an elastomeric shock absorber, consisting of Under the action of a compressive load, which is transferred through the cylindrical body filled with elastomer, through the thrust plate 10 to the elastomer and a rod, one end of which rests on the bottom of the shock absorber 3, the rod 5 enters the cavity of the cylinder body of the device, and on the other, it contains a piston, a dry body 4 and compresses the elastomeric mass, which divides the working chamber of the shock absorber into two, creating high internal pressure, due to the cavity with the possibility of elastomeric flow, energy is absorbed. During shock (explosion of mass from one chamber to another due to calibration pressure) compression of the shock absorber, the absorption gap between the side cylindrical surface of the energy occurs due to the flow (dro

silage) of the elastomeric mass due to the calibration - improvement of the power characteristics of the gap 9 between the side surface of the piston 6 and due to the improvement of the design of its supporting inner surface of the cylindrical body 4. node;

The proposed technical solution has been tested - simplification of the design and improvement of repair - in practice. Absorbent apparatus that offers suitability for the same reason; sia, and is produced, for example, according to the drawing - Increase of the operational resource at the expense of

There are numerous possible variants of known analogues due to the proposed completion of the proposed absorbing device, structural improvement, which confirms the possible - in particular, the height and diameter of the component parts - the ability to achieve the technical result of the object, tomer shock absorber, its location - all that is stated. In known scientific sources, inside the body of the absorbing device, technical and other information has not been found to be absorbed depending on the design process and the devices with the value of the initial tightening force of the device indicated in the useful model, and, by a set of essential features, therefore the proposed is clear, are within the scope of one of the technical solutions is considered to be such that it can receive legal protection in the given area. knowledge, and are considered as being in

The essential difference between the proposed comprehensive scope of the proposed technical decision-making apparatus and the previously known ones is that that its support node is made in the form of an elastomer The quintessence of the proposed technical rhytomer shock absorber, consisting of a cylinder, is that in the design of the absorbing aparadric body filled with elastomer, there is an elastomeric shock absorber, which rod, which at one end rests on the bottom consists of a cylindrical body, filled with the body of the device, and on the other contains a piston, one with elastomer, and a rod, which at one end divides the working chamber of the shock absorber into two. elastomeric contains a piston that divides the working chamber of mass from one chamber to another through a calibrated shock absorber into two cavities with the possibility of a gap between the side cylindrical surface of the flow of elastomeric mass from one chamber to the shaft and the inner surface of the body, while the other through a calibrated gap between the side cylinder and the thrust plate with the help of bolts and mounting brackets with it, the piston and the inner surface of the plate are connected to the body of the device with the possibility of henna of the body, and the thrust plate can be moved relative to it with the help of bolts. The specified difference is that its mounting bars are connected to the body of the device, which ensures the completeness of the power characteristics with the possibility of movement relative to it, thanks to the proposed absorbing device, which contributes to the technical result being achieved. Changing and increasing the resource of its exploitation. None of the use of only individual elements of the design of known absorbing devices can at the same time from the entire set of claimed, naturally, limit to have all the listed properties, since the range of advantages listed above and cannot not include in its composition the whole set be considered a new technical solution in this - essential features declared in the useful model. fins of knowledge, since other similar constructions already

The technical advantages of the proposed absorption will require any creative approach from the hiring apparatus, in comparison with the prototype, perhaps design engineers, and cannot be considered to be attributed to: the results of their creative activity or new objects of intellectual property suitable for protection security documents. 73196 8 45 2 7 Г / и /" и ---и и
