The invention discloses a macpherson type hydro-pneumatic suspension, and belongs to the technical field of hydraulic machinery. The upper end of a cylinder barrel is fixedly connected with an upper hinge in a welding or threaded connection mode, a piston rod is of a hollow structure, and a piston rod inner hole is formed in the piston rod; the large outer circle of the piston rod is matched withan inner hole of a hollow annular guide sleeve, and the guide sleeve is fixedly connected with the lower end surface of the cylinder barrel through guide sleeve bolts which are arranged in the circumferential direction; the piston rod is fixedly connected with a main piston of an annular structure through piston bolts which are arranged in the circumferential direction of the end surface, and thelarge outer circle of the piston rod is matched with a piston inner hole of the main piston; and a radial damping valve is machined at the boundary position where the large outer circle of the pistonrod is matched with the main piston. According to the suspension system, the cylinder barrel and the piston rod can serve as main pins, the structure of the whole suspension system is simplified, andthe macpherson type hydro-pneumatic suspension has a wide application prospect in the field of mines.
本发明公开了一种麦式油气悬挂,属于液压机械技术领域。缸筒的上端与上铰链通过焊接或螺纹连接的方式固连到一起,活塞杆为中空式结构,加工有活塞杆内孔;活塞杆的大外圆与中空的环形导向套的内孔配合安装,导向套与缸筒的下端面通过周向布置的导向套螺栓固连到一起;活塞杆与环形结构的主活塞通过端面周向布置的活塞螺栓固连,活塞杆的大外圆与主活塞的活塞内孔进行配合安装;在活塞杆的大外圆与主活塞配合的边界位置加工有径向的阻尼阀。本发明悬挂系统中的缸筒和活塞杆可以充当主销的作用,简化了整个悬挂系统的结构,在矿山领域拥有广阔的使用前景。
