Description
Technical field
The utility model relates to vibration damping equipment, particularly a kind of pneumatic spring.
Background technique
Mainly contain three class vibration dampers at present: metal spring vibration damper, rubber-metal vibration damper, air-bag shock absorber.Compared with metal spring vibration damper, rubber-metal vibration damper, it is using pressurized gas as working medium that air-bag shock absorber is also called pneumatic spring, there is high flexibility, the natural frequency of vibration is low, highly controlled, the advantages such as proof load is large, are widely used in the industrial fields such as naval vessel, railway locomotive, vehicle at present.
Pneumatic spring to be generally sealed and matched assembling by upper cover plate, air bag and lower cover plate, and the raft frame being arranged on naval vessels reduces the vibration of naval vessels when navigating by water for reducing the mechanical throat sound sent during ship navigating.In technical development process, more and more stricter requirement is proposed to pneumatic spring, need to take into account simultaneously take up room little, lightweight, structure is simple, good stability, displacement capacity waits requirement by force, due to naval vessels sail operating mode cannot foresight, sail climate, ocean environment and seasonal effect larger, running working condition relative complex is changeable, such as when meeting with wave, naval vessels are by sea beat, low during height when naval vessels height across the sea, pneumatic spring absorbs the impact energy suffered by naval vessels, the vibration reducing naval vessels makes naval vessels held stationary, when the larger pneumatic spring of wave punching is by compressive strain, just rigid contact may be produced between upper cover plate and lower cover plate when the Vertical direction of pneumatic spring and the displacement amount of substantially horizontal increase to the limit, when there is the rigid contact between upper cover plate and lower cover plate, the rigidity of pneumatic spring increases on foot cannot carry out isolation damper to connected raft frame, suffered impact force is directly delivered on raft frame by pneumatic spring, the stability that the vibration of raft frame increases naval vessels declines, Security when having influence on ship navigating and riding comfort, therefore the upper cover plate in reduction pneumatic spring and the probability of lower cover plate rigid contact, improve the shock resistance of pneumatic spring, the stability improving ship navigating, Security during increase ship navigating and the effective ways of riding comfort.
Model utility content
The pneumatic spring that the utility model provides, can improve the stability of ship navigating, Security during increase ship navigating and riding comfort.
For achieving the above object, the technical solution adopted in the utility model is: pneumatic spring, comprise upper cover plate, lower cover plate and air bag, air bag and upper cover plate and lower cover plate are sealed and matched formation seal space, characterized by further comprising damping device, described damping device is arranged at and limits described upper cover plate between described upper cover plate and lower cover plate and directly contact with lower cover plate, and it is inner that described damping device is placed in described seal space.
Further, described damping device is ring cushion pad, the bottom that described ring cushion pad is arranged on described upper cover plate does not contact with the upper surface of described lower cover plate, the medial axis of described ring cushion pad overlaps with the medial axis of described upper cover plate, the upper surface center of described lower cover plate has round bump, the diameter of described round bump is less than the diameter of the interior annular distance of described ring cushion pad, described round bump extend into upper cover plate interval in the interior annular distance of described ring cushion pad and described, the bottom surface of described ring cushion pad is less than the perpendicular distance L2 of upper surface to described upper cover plate lower surface of described round bump to the perpendicular distance L1 of described lower cover plate upper surface.
Further, described air bag waist has the thickening utricule portion outstanding to described air bag radial outside.
Further, the material of described ring cushion pad is ultra-high molecular weight polyethylene, teflon, high-elastic polyurethane or rubber-metal sulfuration body.
Further, the utricule of described air bag is divided into inner glue layer, middle hangings lay and outer glue-line, is provided with reinforcing material and makes the waist of described air bag form described thickening utricule portion between the middle hangings lay of described air bag utricule waist location and outer glue-line.
Further, the outlet side of the gas tube of described air bag is positioned at the center of described round bump, and the inlet end of described gas tube is positioned at the bottom of described lower cover plate.
The beneficial effects of the utility model are: pneumatic spring of the present utility model is by upper cover plate, lower cover plate and air bag composition seal space, damping device to be arranged between upper cover plate and lower cover plate and to be placed in seal space, in pneumatic spring stand under load process, though the increase seal space distortion of load increases, the relative position of upper cover plate and lower cover plate changes, damping device limits upper cover plate and contacts with the direct of lower cover plate between upper cover plate and lower cover plate, reduce the probability of upper cover plate and lower cover plate generation rigid contact, improve the shock resistance of pneumatic spring, thus improve the stability of ship navigating, Security when adding ship navigating and riding comfort.
Accompanying drawing explanation
Fig. 1 is the structural representation of pneumatic spring in embodiment.
Fig. 2 is the structural representation of air bag utricule waist in embodiment.
Embodiment
To be further described the utility model by drawings and Examples below.
As depicted in figs. 1 and 2, pneumatic spring, comprises upper cover plate 1, lower cover plate 2 and air bag 3, and air bag 3 is sealed and matched with upper cover plate 1 and lower cover plate 2 and forms seal space 4, also comprise ring cushion pad 5, it is inner that described ring cushion pad 5 is placed in described seal space 4.The bottom that described ring cushion pad 5 is arranged on described upper cover plate 1 does not contact with the upper surface of described lower cover plate 2, the medial axis of described ring cushion pad 5 overlaps with the medial axis of described upper cover plate 1, the upper surface center of described lower cover plate 2 has round bump 21, the diameter of described round bump 21 is less than the diameter of the interior annular distance of described ring cushion pad 5, described round bump 21 extend into upper cover plate 1 interval in the interior annular distance of described ring cushion pad 5 and described, the bottom surface of described ring cushion pad 5 is less than the perpendicular distance L2 of upper surface to described upper cover plate 1 lower surface of described round bump 21 to the perpendicular distance L1 of described lower cover plate 2 upper surface.
When above-mentioned pneumatic spring bearing load, increase seal space 4 along with load is out of shape and increases, the relative position of upper cover plate 1 and lower cover plate 2 changes, first the circular shape cushion pad 5 be fixed on bottom upper cover plate 1 comes in contact with lower cover plate 2, ring cushion pad 5 absorbs a part of load energy, by ring cushion pad 5 flexible contact between upper cover plate 1 and lower cover plate 2, rigid contact between restriction upper cover plate 1 and lower cover plate 2, the rigidity reducing pneumatic spring improves the damping efficiency of pneumatic spring, decrease the probability that rigid contact occurs for upper cover plate 1 and lower cover plate 2, add the shock resistance of pneumatic spring, thus improve the stability improving ship navigating, Security when adding ship navigating and riding comfort.
