Abstract

Заявляемое изобретение относится к транспортному машиностроению, 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 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) неподвижный разделитель (10), который формирует во внутренней полости цилиндра рабочую гидравлическую камеру (11) и основной пневматический упругий элемент, включающий газовую камеру (2), поршень (4) и расположенную над упором часть (12) гидравлической камеры (3). Шток (6) выполнен полым, и его полость разделена установленным в ней разделительным поршнем (15) на газовую камеру (16) и сообщающуюся с рабочей гидравлической камерой (11) полости цилиндра (1) гидравлическую камеру (17), которые совместно с поршнем (15) формируют дополнительный пневматический упругий элемент.The claimed invention relates to transport engineering, and in particular 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 rod (6) associated with the linkage suspension mechanism, or under the influence of excessive gas pressure. The cylinder (1) further comprises a fixed separator (10) equipped with at least one valve (8) and a plurality of throttling holes (9), which forms a working hydraulic chamber (11) and a main pneumatic elastic element including a gas chamber in the inner cavity of the cylinder ( 2), a piston (4) and a part (12) of the hydraulic chamber (3) located above the stop. The rod (6) is hollow, and its cavity is divided by a separating piston (15) installed in it into a gas chamber (16) and a hydraulic chamber (17) connected to the working hydraulic chamber (11) of the cylinder cavity (1), which together with the piston ( 15) form an additional pneumatic elastic element.
