Abstract

The utility model relates to devices for protecting equipment and components of transport systems against dynamic loads and vibrations. The damping fastening device comprises an outer body with resilient cushions. A bushing is secured inside the outer body by means of a resilient annular member. Said bushing is able to slide axially along an inner body. The inner body is provided with an upper and a lower limiting washer. The upper and lower limiting washers are in contact with the resilient cushions. The result is a longer service life and the ability to withstand greater loads.

Description

ДЕМПФИРУЮЩЕЕ УСТРОЙСТВО КРЕПЛЕНИЯ  DAMPING FIXING DEVICE
Полезная модель относится к машиностроению, в частности, к устройствам защиты оборудования, элементов транспортной техники от динамических воздействий и вибраций. The utility model relates to mechanical engineering, in particular, to devices for protecting equipment, elements of transport equipment from dynamic influences and vibrations.
Известен амортизатор шайбовый сетчатый, состоящий из ограничительной втулки, двух защитных колпачков, внутреннего сетчатого элемента, двух внешних сетчатых элементов и двух нажимных шайб (Ильинский B.C. Защита РЭА и прецизионного оборудования от динамических воздействий.-М.:Радио и связь, 1982 г.-стр.244, рис. 8.12). Недостатком описанного устройства является возможность повреждения внутреннего сетчатого элемента о края отверстий защитных колпачков, вследствие того, что внутренний сетчатый элемент не зафиксирован в осевом направлении относительно защитных колпачков.  Known shock absorber washer mesh, consisting of a restrictive sleeve, two protective caps, an internal mesh element, two external mesh elements and two pressure washers (Ilyinsky BC Protection of REA and precision equipment from dynamic influences.-M.: Radio and communications, 1982- p. 244, Fig. 8.12). A disadvantage of the described device is the possibility of damage to the inner mesh element about the edges of the holes of the protective caps, due to the fact that the inner mesh element is not fixed in the axial direction relative to the protective caps.
Указанного недостатка не имеет известное устройство крепления амортизатора подвески автомобиля, содержащее корпус, снабженный с внутренней стороны кольцевым выступом, с одной и другой стороны которого установлены два кольцеобразных эластичных элемента из металлорезины (патент РФ на полезную модель N° 106587). Между кольцевым выступом корпуса и внутренней втулкой с отверстием под шток установлено кольцо фигурной формы, выполненное из металлорезины или неметаллического материала с возможностью фиксации в посадочном месте кольцевого выступа корпуса. По торцам внутренней втулки установлены верхняя и нижняя ограничительные шайбы. Недостатком описанного устройства является снижение срока службы кольца фигурной формы и штока при восприятии подвеской повышенных нагрузок. При указанных нагрузках увеличиваются угловые перемещения штока в зоне фигурного кольца, и от возникающих при этом повышенных изгибающих усилий возможен преждевременный выход из строя штока и фигурного кольца. This drawback does not have the known device for attaching a shock absorber of a car suspension, comprising a housing provided with an annular protrusion on the inside, on the one and the other side of which two annular elastic elements made of metal rubber are installed (RF patent for utility model N ° 106587). Between the annular protrusion of the housing and the inner sleeve with a hole for the rod, a ring of shaped shape is made of metal rubber or non-metallic material with the possibility of fixation in the seat of the annular protrusion of the housing. At the ends of the inner sleeve installed upper and lower restriction washers. The disadvantage described device is to reduce the service life of the ring of a shaped shape and rod when the suspension perceives increased loads. At these loads, the angular displacement of the rod in the area of the figured ring increases, and from the resulting increased bending forces, premature failure of the rod and the figured ring is possible.
Задачей полезной модели является увеличение срока службы при восприятии повышенных нагрузок.  The objective of the utility model is to increase the service life in the perception of increased loads.
Для достижения указанного технического результата предлагается демпфирующее устройство крепления, включающее наружный корпус, с одной и другой стороны которого установлены эластичные подушки. С наружным корпусом через эластичный кольцеобразный элемент соединена втулка, выполненная с возможностью осевого скольжения по внутреннему корпусу. Верхняя и нижняя ограничительные шайбы внутреннего корпуса контактируют с эластичными подушками.  To achieve the specified technical result, a damping fastening device is proposed, including an outer casing, on one and other sides of which elastic pillows are installed. A sleeve is made connected to the outer casing through an elastic ring-shaped element, which is made axially sliding along the inner casing. The upper and lower restriction washers of the inner casing are in contact with the elastic cushions.
Предлагаемое устройство может применяться для защиты от вибраций и динамических воздействий различных объектов техники. В качестве примера на чертеже показан продольный разрез предлагаемого демпфирующего устройства для крепления амортизатора подвески автомобиля.  The proposed device can be used to protect against vibrations and dynamic effects of various objects of technology. As an example, the drawing shows a longitudinal section of the proposed damping device for mounting the shock absorber of the vehicle suspension.
Устройство содержит наружный корпус 1 , с одной и другой стороны которого установлены эластичные подушки 2. С наружным корпусом через эластичный кольцеобразный элемент 3 соединена втулка 4. Втулка 4 выполнена с возможностью осевого скольжения по внутреннему корпусу 5. Например, как показано на чертеже, отверстие втулки 4 сопрягается с цилиндрической поверхностью внутреннего корпуса 5, обеспечивая таким образом возможность скольжения втулки по внутреннему корпусу. Внутренний корпус 5 снабжен верхней 6 и нижней 7 ограничительными шайбами, которые контактируют с эластичными подушками 2. Одним из примеров использования предлагаемого демпфирующего устройства может служить крепление известного штока 8 амортизатора автомобиля, закрепляемого в отверстии внутреннего корпуса 5 с помощью гайки 9. The device comprises an outer case 1, on one side of which elastic pillows 2 are mounted. A sleeve 4 is connected to the outer case through an elastic ring-shaped element 3. The sleeve 4 is axially sliding along the inner case 5. For example, as shown in the drawing, the sleeve bore 4 mates with the cylindrical surface of the inner case 5, thereby allowing the sleeve to slide over the inner case. The inner casing 5 is provided with upper 6 and lower 7 restrictive washers that are in contact with the elastic cushions 2. One of examples of the use of the proposed damping device may be the fastening of the known rod 8 of the shock absorber of the car, fixed in the hole of the inner housing 5 with the help of the nut 9.
Предлагаемое устройство работает следующим образом. При движении автомобиля по неровностям дороги осевые колебания и толчки, приходящие от штока 8 через ограничительные шайбы 6 и 7 передаются на эластичные подушки 2 и демпфируются ими. Радиальные и угловые перемещения штока 8 ограничиваются эластичным кольцеобразным элементом 3, образующим вместе со втулкой 4 упругий шарнир, в результате чего снижаются изгибающие нагрузки на шток в сравнении с прототипом.  The proposed device operates as follows. When the car moves on rough roads, axial vibrations and shocks coming from the rod 8 through the restrictive washers 6 and 7 are transmitted to the elastic cushions 2 and damped by them. Radial and angular movements of the rod 8 are limited by an elastic ring-shaped element 3, forming together with the sleeve 4 an elastic hinge, resulting in reduced bending loads on the rod in comparison with the prototype.
Тем самым увеличивается срок службы штока амортизатора и в целом демпфирующего устройства крепления амортизатора подвески автомобиля при восприятии повышенных нагрузок.  This increases the service life of the shock absorber rod and, in general, the damping device for attaching the shock absorber to the vehicle’s suspension while absorbing increased loads.
