Abstract

The invention relates to means for elastically receiving loads and for deforming oscillations. The invention is characterised in that it uses a conical ring-shaped element which is located between a core and a body. In the first variant, the bearing surface of the body base are embodied such that it is curvilinear and, thereby makes it possible to exclude rupturing pin loads. In the second variant, a core is provided with a projection which is used for forming the deformation chamber of an elastic element.

ПЕРЕЧЕНЬ ЧЕРТЕЖЕЙ Сущность изобретения поясняется чертежами.LIST OF DRAWINGS The invention is illustrated by drawings.
На фиг. l показано упругодемпфирующее устройство по первому варианту, на фиг.2 - упругодемпфирующее устройство по второму варианту.In FIG. l shows an elastic damping device according to the first embodiment, and FIG. 2 shows an elastic damping device according to the second embodiment.
ПРИМЕР РЕАЛИЗАЦИИ ИЗОБРЕТЕНИЯ Упругодемпфирующее устройство по первому и второму варианту содержит корпус, состоящий из цилиндра 1 с внутренним упорным выступом 2 на одном его конце и, по крайней мере, одной цилиндрической проточкой 3 и связанного с ним, например, посредством резьбы основания 4, которое может быть выполнено, например, в виде чашки. О основании выполнено углубление 5 и резьбовое отверстие 6 для элемента крепления 7 амортизатора к несущей конструкции 8 транспортного средства. В корпусе коаксиально установлено: сердечник 9, на выступающей из корпуса части 10 которого предусмотрен нажимной дистанционный элемент 11, закрепленный или за одно изготовленный с ней (для простоты на чертеже не показано) и кольцевой конусообразный упругий элемент 12, в поперечном сечении имеющий форму овала. Упругий элемент с натягом охватывает сердечник 9 и контактирует с основанием 4, нажимным дистанционным элементом и с выступом 2 цилиндра. Сердечник связан с амортизируемым объектом 13 посредством резьбового стержня (болта) 14.EXAMPLE OF IMPLEMENTATION OF THE INVENTION The elastic-damping device according to the first and second embodiment 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. In the housing, it is coaxially installed: 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.
Работают упругодемпфирующие устройства следующим образом.Elastically damping devices operate as follows.
При действии вертикальной нагрузки нажимной дистанционный элемент 11 будет воздействовать на упругий элемент 12, который, деформируясь, заполнит объемы в корпусе 8 и сердечнике 9. В результате большая часть тепловой энергии будет погашена и трансформирована в окружающую среду. При действии горизонтальной силы на амортизатор сердечник 9 вместе с упругим элементом 12 будет перемещаться, а упругий элемент деформироваться в сторону направления силы. Выжимаемый материал упругого элемента 12 заполнит соответствующие объемы в корпусе и сердечнике, трансформирует энергию механического воздействия в его тепло, которое немедленно будет поглощена воздухом. После снятия нагрузок, упругий элемент 12 восстановит свою первоначальную форму и расположение элементов узла.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.
Особенностью узла по первому варианту, является выполнение опорной поверхности 15 основания 4 корпуса по криволинейной образующей, образованной, по крайней мере, одной дугой окружности. Выполнение опорной поверхности 15 криволинейной, позволяет реализовать эффект качения нижнего основания упругого элемента в процессе его деформации и исключить возникновение местных повышенных напряжений в объеме упругого элемента. Выполнение поверхности 15 криволинейной, позволяет также увеличить расстояние между указанной поверхностью и сердечником 9, что способствует более равномерной деформации упругого элемента, т.к. исключает отрыв боковой поверхности упруго элемента от нижней части сердечника.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.
Особенностью узла по второму варианту, является использование вместо колоколообразного сердечника, сердечника с упорным выступом 16, что позволяет создать со стороны сердечника камеру для деформации упругого элемента и уменьшить количество проточек в цилиндре или исключить их полностью.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.
