Abstract
The utility model discloses a brake block that can eliminate vibration noise relates to brake block technical field, to current brake block both sides inclined plane triangle-shaped chamfer structure, because the structure is different, can produce different frequency vibrations in the use, the problem of final noise of formation, the following scheme is put forward now, including the steel sheet, the back fixedly connected with friction material layer of steel sheet, the grooving has been seted up along its direction of height in the front of steel sheet, the both sides of steel sheet are equipped with L type area circular arc chamfer, the back right side of steel sheet is equipped with the warning card. The utility model discloses a through improving and pressing the brake block structure, improve the inclined plane triangle-shaped structure of existing use, make it be "L" type mechanism, change the resonance frequency of brake block to fine play reduces or noise abatement's effect.
Description
Technical Field
The utility model relates to a brake block technical field especially relates to a brake block that can eliminate vibration noise.
Background
The automobile brake pad is also called as automobile brake shoe, and refers to a friction material fixed on a brake drum or a brake disc rotating with a wheel, wherein a friction lining and a friction pad bear external pressure to generate friction action so as to achieve the aim of reducing the speed of the automobile. The automobile brake pad is generally composed of a steel plate, a bonding heat insulation layer and a friction block, the steel plate is coated to prevent rust, and the temperature distribution in the coating process is detected by an SMT-4 furnace temperature tracker in the coating process to ensure the quality.
The existing brake pad with triangular chamfer structures on the inclined surfaces on the two sides can generate different frequency vibration in the use process due to different structures, and finally noise is generated.
SUMMERY OF THE UTILITY MODEL
The utility model provides a can eliminate brake block of vibration noise has solved current brake block both sides inclined plane triangle-shaped chamfer structure, because the structure is different, can produce different frequency vibrations in the use, finally forms the problem of noise.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the brake pad capable of eliminating vibration noise comprises a steel sheet, wherein a friction material layer is fixedly connected to the back of the steel sheet, a cutting groove is formed in the front of the steel sheet along the height direction of the steel sheet, L-shaped circular arc chamfers are arranged on two sides of the steel sheet, and an alarm card is arranged on the right side of the back of the steel sheet.
Preferably, the steel sheet and the friction material layer are pressed and attached at high temperature.
Preferably, one side of the friction material layer, which is far away from the steel sheet, is provided with two alarm card riveting nails, and the alarm cards are fixedly connected with the friction material layer through the alarm card riveting nails.
Preferably, the top of the steel sheet is provided with two fixing grooves along the length direction.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a through improving and pressing the brake block structure, improve the inclined plane triangle-shaped structure of existing use, make it be "L" type mechanism, change the resonance frequency of brake block to fine play reduces or noise abatement's effect.
Drawings
Fig. 1 is a schematic front view of a brake pad capable of eliminating vibration noise according to the present invention;
fig. 2 is a schematic top view of the brake pad of the present invention for eliminating vibration noise.
In the figure: 1 steel sheet, 2 warning cards, 3 friction material layers, 4 grooving, 5 warning card riveting nails and 6L-shaped belt arc chamfers.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-2, a brake pad capable of eliminating vibration noise comprises a steel sheet 1, a friction material layer 3 is fixedly connected to the back of the steel sheet 1, a cutting groove 4 is formed in the front of the steel sheet 1 along the height direction of the steel sheet, L-shaped arc chamfers 6 are arranged on two sides of the steel sheet 1, and an alarm card 2 is arranged on the right side of the back of the steel sheet 1.
In this embodiment, the steel sheet 1 and the friction material layer 3 are formed by high-temperature press bonding.
In this embodiment, friction material layer 3 is kept away from one side of steel sheet 1 and is equipped with two warning card riveting nails 5, and warning card 2 passes through warning card riveting nail 5 and friction material layer 3 fixed connection.
In this embodiment, two fixing grooves are formed in the top of the steel sheet 1 along the length direction thereof.
The working principle is that firstly, the automobile brake pad is mainly formed by pressing and attaching a steel sheet 1 and a friction material layer 3 at high temperature. Be equipped with warning card riveting nail 5 on the 1 back of steel sheet, warning card riveting nail 5 is used for riveting warning card 2, and the vertical central point of steel sheet 1 puts standard height grooving 4 for dispel the heat and lead the ash in the brake block use, and 2 both sides of friction material layer have "L" type area circular arc chamfer 6 from outside to inside, and this L type structure is of value to the noise that produces in reducing the product use, promotes the product quality.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
