Abstract
The utility model relates to a composite shock-absorbing and muffling plate, which comprises a metal base plate; wherein, a paint film is coated on the facade of the metal base plate; in the metal base plate, a tinplate is positioned under the paint film, a viscoce layer is positioned under the tinplate, and a stainless steel plate is positioned under the viscoce layer. The utility model is characterized by firm structure, outstanding shock-absorbing and muffling effects, and the like. In particular, the composite shock-absorbing and muffling plate also can insulate heat. Compared with the ordinary brake pad, since the viscoce layer is viscoelastic polymer material and a poor conductor of heat, the heat-insulating property of the viscoce layer can insulate the high temperature generated by the braking of the brake pad, consequently, the oil in a braking oil tube can be prevented from being gasified, braking failure can be avoided, and the safety of drivers can be ensured.
Description
Technical field
The utility model relates to the parts of automobile brake sheet, especially relates to a kind of composite shock-absorbing silencing piece.
Background technology
Shock absorption sound deadening sheet is a kind of vitals of brake facing, and it is arranged under the steel backing of brake facing, and at the brake facing glancing impact, vibrations and noise that the brake facing pad is brought play certain shock damping action.Along with the fast development and the human progress of auto-industry, at a high speed, safe, reliable, comfortable main long-standing the asking that has become people driving.Yet, existing most of shock absorption sound deadening sheets adopt the general steel sheet punching press to make, its damping and silencing poor-performing, easy-to-rust in the use particularly can not be heat insulation, if the brake facing frequently braking, the high temperature of its generation conducts to brake oil pipe by shock absorption sound deadening sheet, impel the vaporization of oil in the brake oil pipe, thereby might cause brake failure, threaten driver's safety.Therefore the vibration damping sheet of existing structure needs of incompatibility automobile industry development.
Summary of the invention
The utility model purpose provides a kind of shock absorption sound deadening sheet, and is relatively poor to solve the existing existing shake performance muffler of shock absorption sound deadening sheet, easy-to-rust in the use, can not be heat insulation etc. technical matters.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: described shock absorption sound deadening sheet, comprise metal substrate, front surface coated at metal substrate has paint film, in the described metal substrate, being positioned at below the paint film is tinplate, is adhesive-layer below the tinplate, is stainless steel sheet below the adhesive-layer.
As a kind of preferred version of the present utility model, described tinplate surface also has a phosphate coating.
Therefore, the utlity model has characteristics such as sound construction, damping soundproof effect be outstanding.The metal substrate damping coefficient height of this vibration damping sheet, when vibration took place vibration damping sheet, the viscoelastic colloidal between the metal sheet was forced to stretch, and produced bigger shearing stress and strain in the layer, so the consume more energy produces the antidetonation noise reduction effect.The utility model especially can also be heat insulation, compare with common brake facing, because adhesive-layer is viscoelastic High molecular material, it is the bad conductor of heat, the high temperature that the heat-proof quality of this glue produces when making the brake facing brake is intercepted, thereby prevent the vaporization of oil in the brake oil pipe, avoid brake failure, guaranteed driver's safety.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is A shown in Figure 1---the A cutaway view;
Fig. 3 is a B shown in Figure 2 place partial enlarged drawing.
The specific embodiment
Fig. 1 is the structural representation of a kind of embodiment of the utility model.Fig. 2 is its A-A cutaway view; By Fig. 1 and in conjunction with Fig. 2 as can be known, this shock absorption sound deadening sheet is mainly by substrate, and the paint film that covers on the substrate constitutes.Described paint film can be heat-resisting, has certain cushioning ability.
In substrate, being positioned under the paint film 1 is tinplate 3, is adhesive-layer 4 under the tinplate, is stainless steel sheet 5 under the adhesive-layer.Stainless steel sheet has the superior corrosion resistance energy, so the surface does not need the coating oil lacquer coat.
Adhesive-layer 4 is made up of viscoelastic High molecular material, this material clip between two-layered steel plates, strike up, vibration damping sheet sends dull uncut jade uncut jade sound, this is because the various materials in substrate all have different sound absorbing powers, after above-mentioned material was combined with each other, vibration and noise were decayed in substrate and are exceedingly fast.
By Fig. 3 further as can be known, tinplate 3 positive and negative surfaces also have a phosphate coating 21,22.This phosphate coating obtains after handling by phosphatization liquid.Wherein the phosphate coating 21 of front surface can increase the binding power with paint film 1, and the phosphate coating 22 of reverse side can increase the binding power with adhesive-layer 4.
Claims (2)
1. a composite shock-absorbing silencing piece comprises metal substrate, in the front surface coated of metal substrate paint film is arranged, and it is characterized in that in the described metal substrate, and being positioned at below the paint film is tinplate, is adhesive-layer below the tinplate, is stainless steel sheet below the adhesive-layer.
2. composite shock-absorbing silencing piece according to claim 1 is characterized in that described tinplate surface also has a phosphate coating.
