(54) АМОРТИЗАТОР(54) SHOCK ABSORBER

1one

Изобретение относитс  к машиностроению и касаетс  конструкций амортизаторов, используемых в буферных устройствах, виброизолирующих опорах и. других механизмах дл  поглощени  ударной нагрузки и гащени  колебаний подрессоренной массы, sFIELD OF THE INVENTION The invention relates to mechanical engineering and relates to structures of shock absorbers used in buffer devices, anti-vibration supports and. other mechanisms for absorbing shock and vibration damping, s

По основному авт. св. № 750174 известен амортизатор, содержащий заполненный рабочей средой корпус с перегородкой, в которых выполнены соосные отверсти  и ступенчатый плунжер, разные диаметры которого расположены в соответствующих отверсти х корпуса и перегородки, причем дл  осуществлени  гашени  колебаний при обратном ходе больща  ступень плунжера расположена в отверстии перегородки 1.According to the main author. St. No. 750174 is known a shock absorber comprising a housing filled with a working medium with a partition wall in which coaxial holes and a stepped plunger are made, different diameters of which are located in the corresponding holes of the housing and the partition wall, moreover, to suppress oscillations during the reverse course, the larger step of the plunger is located in the opening of the partition 1 .

Однако извесБный амортизатор не обеспечивает одинаковую упругую характеристику при пр мом и обратных ходах плунжера .However, a known shock absorber does not provide the same elastic response in the forward and reverse strokes of the plunger.

Цель изобретени  - обеспечение одимаковой упругой характеристики при пр мом и обратном ходах плунжера.The purpose of the invention is to provide odomonic elastic characteristics in the case of forward and reverse plunger strokes.

Указанна  цель достигаетс  тем, что в корпусе выполнено соосное отверстие, в котором установлена меньша  ступеньThis goal is achieved by the fact that a coaxial hole is made in the housing, in which a lower stage is installed

плунжера, а полости, разделенные перегородкой , выполнены равными.plunger, and the cavity separated by a partition, are made equal.

На чертеже показан амортизатор, продольный разрез.The drawing shows a shock absorber, a longitudinal section.

Амортизатор содержит корпус 1, разделенный перегородкой 2 на равные по объему полости 3 и 4, заполненные эластомером . В -корпусе 1 и перегородке 2 выполнены соосные отверсти , в которых установлен ступенчатый плунжер 5, разные диаметры которого расположены в соответствуюших отверсти х корпуса 1 и перегородки 2, причем больща  ступень плунжера 5 расположена в отверстии перегородки 2, а меньща  ступень - в отверсти х корпуса 1.The absorber includes a housing 1, divided by a partition 2 into equal cavities 3 and 4, filled with elastomer. In the casing 1 and the partition 2 there are made coaxial holes in which a stepped plunger 5 is installed, the different diameters of which are located in the corresponding openings of the housing 1 and the partition 2, with the greater plunger step 5 located in the opening of the partition 2, and a smaller step in the openings housing 1.

Амортизатор работает следующим образом .The shock absorber works as follows.

При- движении плунжера 5 в направлении стрелки происходит сжатие эластомера в полости 4 большей ступенью, т. е. шейкой 6.When the plunger 5 moves in the direction of the arrow, the elastomer is compressed in the cavity 4 by a larger step, i.e. the neck 6.

При уменьшении нагрузки, приложенной к плунжеру 5, происходит и его перемеще ;1е в обратном направлении за счет потенциальной энергии эластомера, наход щегос  в полости 4, с одновременным ежатием шейкой 6 эластомера в полости 3, что обеспечивает торможение при обратном движении плунжера.When the load applied to the plunger 5 is reduced, it is also moved; 1e in the opposite direction due to the potential energy of the elastomer located in cavity 4, with the elastomer neck 6 simultaneously in cavity 3, which ensures braking during the reverse movement of the plunger.

При этом обеспечиваетс  одинакова  упруга  характеристика при пр мом и обратном ходе плунжера.In this case, the same elastic characteristic is ensured during the forward and reverse course of the plunger.
