Abstract
Provided is an automobile brake disc with vibration-damping and sound-absorbing function, which relates to the technical field of vibration damping and sound absorbing of a brake disc. The automobile brake disc comprises a steel disc (1), a brake disc (2), sintering metal porous materials (3), a circular hole (4), and a bonding layer (5). A cylinder body made from the sintering metal porous materials (3) can not only stably combine the steel disc (1) and the brake disc (2) to prevent the delaminating between the brake disc and a base plate, but also can have the capability of vibration damping, sound insulating and sound absorbing to achieve the quiet and comfortable effect of an automobile. When the brake disc is worn to a certain degree, the bonding layer can be carbonized through high temperature. A new brake disc is replaced, and thereby the steel disc (2) can be reused, and resource waste can be prevented.
Description
Technical field:
The utility model relates to the brake block technical field, is specifically related to a kind of automobile brake sheet with damping, sound absorption function.
Background technique:
Chinese Automobile Industry ' develops rapidly and has driven other industries and constantly bring forth new ideas and improve.The automobile brake sheet manufacturing industry is one of indispensable industry in the automobile making, constantly has in recent years new technology to emerge in large numbers.Brake block generally is made of steel plate, bonding thermal-protective coating and brake pad, and wherein thermal-protective coating is comprised of adiabatic material, and purpose is heat insulation.Brake pad is comprised of friction material, tackiness agent, is compressed in during brake to produce friction on brake disc or the brake drum, thereby reaches the purpose of vehicle deceleration brake.In the brake process of automobile, friction material layer and mutually mutual friction of brake disc, the braking force of generation automobile.
For a long time, vibration and noise are large major issues of automotive engineering research always, and along with the speed up of automobile and the people raising to the car comfort requirement, the vehicle vibration damping technology becomes automotive research and designs important topic.When automobile emergency brake, the friction of brake disc and brake block can produce vibration and sharp-pointed noise.Therefore, a kind of pursuit low noise, vibration damping, braking, the brake block that Security is good has been the product of being badly in need of serious hope in the production in automobile industry.The sintering metal porous material has the characteristic of metallic material and porous material, it is a kind of novel structure function material, be characterized in that inside contains a large amount of connections or semi-connected hole, have that relative density is low, specific strength is high, high temperature resistant a, sound insulation, the advantage such as heat insulation.If it is used in the brake block, brake block will have the ability of damping, sound insulation, sound-absorbing.
In addition, when friction material thickness may wear to certain limit, must in time change brake block.General brake block goes out of use after friction material has worn and torn, and this is just in the waste of the pollution that has become environment and resource.
The model utility content:
The purpose of this utility model provides a kind of automobile brake sheet with vibration damping, sound absorption function, its reasonable idea, advanced design, easily processing, the cylinder of making by the sintering metal porous material not only firmly combines brake block and steel backing, prevent brake block and base plate delamination, also have the ability of damping, sound insulation, sound-absorbing, reach the quiet comfortable effect of automobile.In addition, after brake block may wear to a certain degree, make the adhesive layer carbonization by high temperature, the brake block that more renews, avoided resource waste.
In order to solve the existing problem of background technique, the utility model is by the following technical solutions: it comprises steel disc 1, brake block 2, sintering metal porous material 3, circular hole 4, adhesive layer 5.
5 circular holes 4 of mutual perforation are respectively arranged on described steel disc 1 and the brake block 2, and the diameter in hole is 4mm.
Described sintering metal porous material 3 is installed in the circular hole 4, and wherein the micron order holes are adopted in sintering metal porous material 3 inside, and the aperture minimum reaches 2um～3um.Sintering metal porous material 3 is with steel disc 1 and brake block 2 usefulness porous materials are compound is bonded together with the EVA adhesive, and adhesive property is good, and is free from environmental pollution.
After brake block may wear to a certain degree, make the adhesive layer carbonization by high temperature, the brake block friction material that more renews.Steel disc 1 be can take full advantage of, the pollution of environment and the waste of resource reduced.
The utlity model has following beneficial effect: the cylinder of making by the sintering metal porous material on the one hand not only firmly combines brake block and steel backing, prevents brake block and base plate delamination.On the other hand, also have the ability of damping, sound insulation, sound-absorbing, reach the quiet comfortable effect of automobile.In addition, after brake block may wear to a certain degree, make the adhesive layer carbonization by high temperature, the brake block that more renews, avoided resource waste.
Description of drawings:
Fig. 1 is the utility model brake block structure schematic representation;
Fig. 2 is the utility model brake block steel disc structural representation.
Embodiment:
Referring to Fig. 1 and Fig. 2, this embodiment is by the following technical solutions: it comprises steel disc 1, brake block 2, sintering metal porous material 3, circular hole 4, adhesive layer.
5 circular holes 4 of mutual perforation are respectively arranged on described steel disc 1 and the brake block 2, and the diameter in hole is 4mm.
Described sintering metal porous material 3 is installed in the circular hole 4, and wherein the micron order holes are adopted in sintering metal porous material 3 inside, and the aperture minimum reaches 2um～3um.Sintering metal porous material 3 is with steel disc 1 and brake block 2 usefulness porous materials are compound is bonded together with the EVA adhesive.
In addition, the raw material of brake block is heat sealing on the base plate by high temperature hot pressing.After brake block 2 may wear to a certain degree, make the adhesive layer carbonization by high temperature, the friction material that more renews can reuse steel disc 2, avoided resource waste.
[0017] this embodiment is simple in structure, and is reasonable in design, improved steel disc 1 and brake block 2 in conjunction with soundness, effectively reduced because of the fricative vibration of brake block and noise, reach the quiet comfortable effect of automobile.
