Abstract
The present invention belongs to a spring, and includes a spring body, and a damping structure, which generates a viscous damping action to the motion of the spring body and contains liquid damping material. An external sealing protective layer is arranged out of the liquid damping material. The invention is characterized in that the spring body is at least partially dipped in the liquid damping material, the liquid damping is arranged in an interlayer between the external sealing protective layer and an internal sealing protective layer, the internal sealing protective layer is composed of an elastic material. Since the spring adopts the highly viscous liquid damping material, the spring can provide a relatively high damping ratio, which is sufficient for the vibration reduction of most of mechanical devices and vehicle structures, normally, an additional damping device is no longer needed, and therefore the structure is simplified. Because the spring is in the damping liquid or the elastic material, the spring can be prevented from oxidizing and rusting.
Description
Technical field
The present invention is that application number is 200310105524.9 divides an application, and belongs to damping spring.
Background technique
Common spring generally is made by pure elastic material, and its damping is very little, especially metal spring.In practice, in order to increase its damping, sometimes adopt with spring outside cover one deck rubber pipe or in the surperficial way of vulcanizing General Purpose Rubber of spring, a kind of low resistance but General Purpose Rubber is fundamentally said so, elastomeric viscoelastic material, under the high frequency action condition, as vibration and noise to audio range, have certain damping, concerning most of mechanical vibration, its damping ratio has only 1-3%, damping ratio is littler during in parallel use with spring, in most of the cases damping ratio is nowhere near, for example for general vehicle, the vibration damping of equipment and vibration isolation require damping ratio between 10%-30%, at this moment must cooperate extra damping device to use, make complex structure.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, a kind of spring that has damping itself is provided.
For achieving the above object, the present invention is provided with the damping structure that contains the liquid damping material that movement of springs is produced damping function on the spring body.
The said spring of the present invention can be any spring, but mainly is helical spring or dish spring, and it immerses in the liquid damping material at least in part, and spring is at least one, also can be a plurality of serial or parallel connections.
The said damping material of the present invention, comprise any liquid damping material that has the higher material damping ratio, enough dampings can be provided, for stable performance, volatile, not ageing-resistant high viscosity liquid, for example be the improvement pitch of viscous state etc. under silicone oil and the operating temperature.
In order to make the easy centering of spring body and spring, in the upper end or the lower end of spring body the centering piece structure is set, centering piece is in order to prevent the horizontal slippage of spring with respect to the working position, the general sheet metal that adopts band cylindrical or interior circle.Visible other function of centering piece.
For the series connection of multi-disc dish spring, guiding element also to be set or utilize higher elastic material of intensity such as rubber that the dish spring is constrained to one, to prevent the horizontal mutual dislocation of dish spring, guiding element preferentially adopts wear-resisting metal tube or rod.When hermetically sealed, the guiding element place adopts seal ring to connect sealing.
Liquid damping material in the spring preferentially adopts full-closed structure with convenient transportation.
Such scheme can be following concrete scheme:
1) spring silk or reed immerse in the liquid damping material, and in the interlayer of liquid damping material between inside and outside two seal protection layers, the metal ring sealing is adopted in the top and bottom of interlayer; Inner sealant layer adopts elastic material or solid damping material.
2) the spring silk is partially submerged in the tubular body that is made of elasticity or viscoelastic material, has with the spring silk between the inherent spring silk of tubular body and extends consistent cavity, fills the liquid damping material in the cavity; The hollow interior filling liquid damping material of tubular body, inner tube wall has the mechanism that increases resistance to motion.
3) spring silk or reed embed in the tubular body that is made of elasticity or viscoelastic material, and belt cavity is arranged in the tubular body, fill the liquid damping material in the cavity.
4) helical spring spring silk is surperficial with seal protection layer, perfusion fluid damping material in the interlayer between seal protection layer and the spring silk surface.
5) a plurality of springs embed in the cylindrical body that is made of elastic material or solid damping material side by side, between cylindrical body spring center or the spring cavity are set, and filling liquid damping material in the cavity is provided with the mechanism that increases spring body resistance to motion.
Spring body quantity in the such scheme can be several, can serial or parallel connection.
The present invention is owing to originally be provided with damping structure on one's body at spring, and when vibration or distortion took place spring stress, damping material produced distortion thereupon, can produce very big interior friction in the damping material, consumes portion of energy.Feasible distortion is subjected to hindering, vibration is decayed; Because noise also vibrates and causes, so noise also alleviates greatly.The present invention is owing to adopted the high viscosity liquid damping material, higher damping ratio is provided, vibration damping to most machinery and vehicle structure can provide enough damping ratios, even in the very high occasion of the damping ratio of needs, what required extra damping also can be little is many.Just no longer need to cooperate in addition damping device in the ordinary course of things, thereby simplify the structure.In addition, the present invention has also eliminated this resonance under natural frequency of spring effectively.Because spring is among damping liquid or elasticity, year elastic material, also can prevent the spring oxidation corrosion.
