Abstract
The invention relates to a damping spring. The damping spring comprises a spring body which is made of metal, and also comprises a macromolecule damping material which can generate the damping effect to the movement of the spring. The damping spring provided by the invention has the beneficial effects that the damping spring has a simple structure and good damping effect.
Description
Technical field
The present invention relates to a kind of spring, especially a kind of spring with damping function.
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 asking at 10%-30%, at this moment must cooperate extra damping device to use, make complex structure.Therefore, need a kind of simple in structure, damping spring that damping is good of design.
Summary of the invention
In order to overcome above defective, the technical problem to be solved in the present invention is: propose a kind of spring with damping function.
The technical solution adopted in the present invention is: a kind of damping spring, comprise the spring body that is made of metal, and also comprise the macromolecular damping material that movement of springs is produced damping function.
In a preferred embodiment of the present invention, described macromolecular damping material is the mixture of polyacrylate rubber and chlorinated polypropylene.
In a preferred embodiment of the present invention, add hindered phenol in the mixture of described polyacrylate rubber and chlorinated polypropylene.
In a preferred embodiment of the present invention, bonding between described spring body and the macromolecular damping material by binder.
The invention has the beneficial effects as follows: disclosed damping spring, it is simple in structure, damping good.
Description of drawings
Fig. 1 is the structural representation of the preferred embodiments of the present invention;
Among the figure: 1. spring body; 2. macromolecular damping material.
Embodiment
The present invention is further detailed explanation with preferred embodiment in conjunction with the accompanying drawings now.These accompanying drawings are the schematic representation of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
The present invention has disclosed a kind of damping spring, comprises the spring body 1 that is made of metal, and the vibration that the pure metal spring produces at the volley is bigger, in order to reduce vibration, just need increase damping to metal spring.In the preferred embodiment of the present invention, adopted the mode of having filled macromolecular damping material 2 in the centre of spring body 1 with damping function.Because macromolecular damping material itself can not be used as structural material, it must be bonded on the spring as oscillating body, and therefore, it is bonding to pass through binder between spring body 1 and the macromolecular damping material 2.
Further, macromolecular damping material 2 is the mixture of polyacrylate rubber and chlorinated polypropylene.Add hindered phenol in the mixture of polyacrylate rubber and chlorinated polypropylene, hindered phenol not only can improve damping capacity, but also has shown than the much better cementability of binder commonly used.
Disclosed damping spring, it is simple in structure, damping good.
With above-mentioned foundation desirable embodiment of the present invention is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must determine its technical scope according to the claim scope.
Claims (4)
1. a damping spring comprises the spring body that is made of metal, and it is characterized in that: also comprise the macromolecular damping material that movement of springs is produced damping function.
