Abstract
The invention provides a kind of inner-hided gasbag type bi-exit bar magnetic current deformation fluid damper. It includes jar body, piston set in the jar body, exciting coil installed on the piston, two piston rods installed on the two ends of the piston, seal body of the two ends of the jar body and magnetic current deformation fluid filled in the jar body. There is slit between the piston and the inner wall of the jar body. Annularity gasbag with gas injection hole held out of the jar body is installed in the jar body. The gasbag of the invention is designed to annularity, and installed in the jar body; the whole structure is compact and simple, has no obvious bulge out of the jar body on the situation of reaching the good adjusted fluid volume difference; the occupied space is small; its appearance is goodly; the installation is convenience; it is not easy to be destroyed; its using life is long.
Description
(1), affiliated field
What the present invention relates to is a kind of vibration damping equipment.Specifically a kind of passive energy dissipation device that is used for automobile, machinery, bridge and civil structure.
(2), background technique
The existing pair of outstretch pole magnetorheological fluid damper generally all exists because of leak of liquid and to include bubble etc. former thereby cause the discontented problem of filling, thereby influence the energy dissipation capacity of damper under little amplitude.In addition, this type of damper is when temperature variation, because fluid is different with the thermal expansion coefficient of cylinder body, when temperature reduced, the fluid contraction amount was greater than the cylinder body contour projector, thereby further reduced the energy dissipation capacity of damper under little amplitude; When temperature raises, then there is the danger of cylinder body blast.In recent years, someone attempts to solve above problem by the method that accumulator is installed in the outside of damper, though this method principle is feasible, there are cost height, complex structure, shortcomings such as destruction easily take place the interface big, that inconvenience, damper and accumulator are installed that takes up room.Limited its application in all kinds of dampers.
(3), summary of the invention
The object of the present invention is to provide a kind of simple in structure, easy for installation, hysteresis loop is full, it is little to take up room, the two outstretch pole magnetorheological fluid dampers of the built-in air sac type of long service life.
The object of the present invention is achieved like this: it comprises cylinder body, be arranged at the piston in the cylinder body, be installed in the field coil on the piston, be installed in two piston rods at piston two ends, the seal at cylinder body two ends and the magnetic flow liquid that is filled in the cylinder body, leave the slit between piston and the inboard wall of cylinder block, in cylinder body, be provided with ring-shaped gasbag, have on the ring-shaped gasbag and stretch out the outer injecting hole of cylinder body.
The present invention can also comprise some structure characteristics like this:
1, is provided with protective casing between the interior ring of described ring-shaped gasbag and the piston rod.
2, two piston rods stretch out the seal that overlaps end of body respectively, have the connection earrings in the end of piston rod.
3, piston rod stretches out the seal of cover end of body, has the connection earrings in the end of piston rod, and another piston rod extend in the groove on the seal, connects earrings and is installed on seal or the cylinder body.
4, described ring-shaped gasbag has 1, is positioned at the inboard of the seal of an end.
5, described ring-shaped gasbag has 2, lays respectively at the inboard of the seal at two ends.
5, have 1-10 groove on the piston, 1-10 field coil is set in the groove.
Working principle of the present invention is:, internal memory bubble discontented because of pouring into when the volume of fluid or temperature drop etc. are former thereby during less than the volume of oil cylinder, and gassiness air bag can expand and mend the difference in volume of no fluid volume and cylinder body.When fluid expands because of temperature rise, can by air bag under fluid pressure action contraction and the expander product moment of absorption fluids and cylinder body, to avoid the blast of cylinder body.
Airbag design of the present invention circlewise, air bag is arranged in the cylinder body, under the prerequisite of the adjustment fluid volume difference that guarantees to reach good, makes compact overall structure, simple, cylinder body is outer not to be had and significantly protrudes the position, little, the beautiful shape of taking up room, easy for installation, not fragile, long service life.
