Abstract

Заявляемое изобретение относится к транспортному машиностроению, в частности к гидропневматическим подвескам транспортных средств, а именно к гидропневматическим цилиндрам подвески. Предложен гидропневматический цилиндр подвески, содержащий цилиндр (1), герметичная внутренняя полость которого разделена на газовую (2) и гидравлическую (3) камеры посредством поршня (4), который совершает возвратно-поступательное перемещение вдоль оси (5) цилиндра под действием давления жидкости вследствие перемещения телескопического штока (6), связанного с рычажным механизмом подвески, или под действием избыточного давления газа. Цилиндр (1) дополнительно содержит снабженный по меньшей мере одним клапаном (8) и множеством дросселирующих отверстий (9) разделитель (10), который формирует во внутренней полости цилиндра рабочую гидравлическую камеру (11) и пневматический упругий элемент, включающий газовую камеру (2), поршень (4) и расположенную над разделителем часть (12) гидравлической камеры (3).The claimed invention relates to transport engineering, in particular to hydropneumatic suspensions of vehicles, namely to hydropneumatic suspension cylinders. A hydropneumatic suspension cylinder is proposed comprising a cylinder (1), the sealed internal cavity of which is divided into a gas (2) and a hydraulic (3) chamber by means of a piston (4), which performs reciprocating movement along the axis (5) of the cylinder under the action of liquid pressure due to moving the telescopic rod (6) associated with the linkage suspension mechanism, or under the influence of excessive gas pressure. The cylinder (1) further comprises a separator (10) provided with at least one valve (8) and a plurality of throttling holes (9), which forms a working hydraulic chamber (11) and a pneumatic elastic element including a gas chamber (2) in the inner cavity of the cylinder , a piston (4) and a part (12) of the hydraulic chamber (3) located above the separator.
