Description
Technical field
The present invention relates to a kind of damper, in particular to a kind of spiral energy-consumption dampers.
Background technology
Damper is to provide the resistance of movement, and the device of depletion kinergety is answered using damping come energy-absorbing damping extensively
For in the industries such as space flight, aviation, military project, firearms, automobile, motorcycle.Currently, relatively common damper mainly has hydraulic pressure viscous
Stagnant damper, if China Patent Publication No. is shown in CN201908986 U, which is to apply resisting medium and damping
The interaction of device structure member generates a kind of passive velocity correlation type product that the principle of damping force designs and produces.But this is viscous
When in use, such as applied to lift car, bridge or when building buffering, internal viscous oil is easy stagnant damper
Leakage, results in the need for often supplementing viscous oil, and the damper is led in the bottom that issues of terraced car, bridge or building
Cause the viscous oil repair of supplement very inconvenient.
Invention content
The purpose of the invention is to overcome shortcoming and defect of the existing technology, and provide a kind of structure design conjunction
Reason, it is easy to maintain, and a kind of spiral energy-consumption damper of good buffer effect.
