近年来,在挖掘机、工业拖拉机等工程机械悬架或支座中,利用机器本身的液压或气动操纵系统的压力源,配以有良好减振性能的液压或气动的减振器,使机器的动载荷显著降低,运行平稳。已日渐广泛。带有节流孔的活塞式液压与气动减振器(以下均简称为液压或气动减振器),当前采用的较为普遍,因为它具有如下的一些重要特点:结构简单、重量轻
In recent years, hydraulic or pneumatic shock absorbers with excellent vibration damping properties have been used in hydraulic or pneumatic control systems of hydraulic excavators, industrial tractors, and other engineering machinery suspensions or bearings to make machines. The dynamic load is significantly reduced and the operation is smooth. It has become increasingly widespread. Piston type hydraulic and pneumatic shock absorbers with orifices (hereinafter abbreviated as hydraulic or pneumatic shock absorbers) are currently used because it has some important features such as: simple structure, light weight
