Because the utility model has adopted above technological scheme, adopt on one active chamber and active chamber once, between adopt connecting tube to connect, and by active chamber on the electromagnetic valve that is arranged on connecting tube and the once connection and the partition of active chamber, therefore, when by the device for vibration insutation unstability, can rush at snubber with big speed, solenoid valve on the snubber is sensed this pressure and can be opened, active chamber and following active chamber communicate on this moment, working solution flows into active chamber down by last active chamber under pressure, and following active chamber expands rapidly, and snubber shows as flexibility.When impacting end, last active chamber resets, and following active chamber shrinks, and the working solution under flowing in the active chamber flows back to active chamber again, closed electromagnetic valve, and snubber returns to normal state.Can avoid or reduce secondary pulse.
Description of drawings
Concrete characteristic performance of the present utility model is further provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the structural representation of the utility model intelligence snubber.
Embodiment
See also Fig. 1.The utility model intelligence snubber comprises mounting plate 1, last active chamber parts 2, following active chamber parts 3 and pressure release parts 4.
Described mounting plate 1 can be made of a plate, also can be made of superimposed two boards.Present embodiment is to be formed by stacking by last working surface mounting plate 11 and following working surface mounting plate 12.
Described upward active chamber parts 2 are arranged on the end face of working surface mounting plate 11, it comprises a last working surface 21 that is made of thicker rubber, the periphery that should go up working surface 21 is connected with the mounting plate end face, make described going up form active chamber 22 between working surface and the last working surface mounting plate end face, on described, be full of working solution 23 in the active chamber.
Described active chamber parts 3 down are arranged on down the bottom surface of working surface mounting plate 12, it comprises a following working surface 31 that goes in ring and be provided with, described working surface down is made of the belt thin rubber capsule that is easy to expand, and forms a following active chamber 32 that goes in ring between the bottom surface of this time working surface and following working surface mounting plate 12.
The wall thickness of the last working surface of the utility model intelligence snubber will be thicker than down the wall thickness of working surface, and when specifically being under pressure pressure release with described last working surface, described working surface down can expand automatically rapidly to damage and be as the criterion.Can determine according to different use occasions.
The utility model also comprises pressure release parts 4, and it comprises a connecting tube 41 and a solenoid valve 42.Correspondence is provided with a through hole 111,121 on working surface mounting plate on the active chamber zone on described being positioned at and following working surface mounting plate, also is provided with a through hole 311 on the rubber cyst wall of described working surface down; Described connecting tube 41 is communicated with between the through hole that is provided with on through hole that is provided with on the described mounting plate and the following working surface; Described solenoid valve 42 is arranged on the connecting tube, and the connected sum in the control between active chamber and the following active chamber cuts off.Solenoid valve is opened, and active chamber communicates up and down; Closed electromagnetic valve, active chamber cuts off up and down.The specific requirement of the occasion that the threshold values that solenoid valve opens or closes can use according to this intelligence snubber is decided.
