The utility model also provides a brake block, this brake block is including above -mentioned make an uproar brake block steel backing and the friction material of bonding on this falls the brake block steel backing of making an uproar of falling. Owing to be equipped with on the steel backing body and fall the hole of making an uproar, not only can reduce the braking noise, can also increase steel backing body and friction material's degree of adhesion to the shear strength of reinforcing brake block improves braking safety.
Description
Technical field
This utility model belongs to brake block technical field, is specifically related to a kind of noise reduction brake block steel back and includes the brake block of this noise reduction brake block steel back.
Background technology
In automobile brake system, brake block, as the parts of most critical, plays decisive role to the quality of brake system.Brake block generally comprises the steel back of the body, friction material, binding agent；Steel is shouldered carrying, is supported the effect of friction material.During brake, the steel back of the body is promoted by braking clamp, friction material and brake disc or drum CONTACT WITH FRICTION, is reached the purpose of vehicle deceleration by friction.
But, in brake process, comfort level by bus is produced a very large impact by the brake noise that braking produces, and the suppression of the noise of generation in braking procedure has been become an important topic of brake block technical field.Accordingly, it would be desirable to the structure of brake block is optimized, meet existing demand.Existing brake block steel back has two or more fabrication hole mostly, but its main purpose is for locating and machining, increases shear strength to a certain extent, does not solve a difficult problem for brake noise.
Therefore, a kind of degree of adhesion that both ensure that with friction material, can reduce noise again, the brake block steel back of brake safe urgently occurs.
Utility model content
The deficiency existed for prior art, this utility model provides a kind of noise reduction brake block steel back, can reduce brake noise, can increase again the degree of adhesion with friction material, and enhance the shear strength of brake block, improve brake safe.
For solving above-mentioned technical problem, this utility model provides a kind of noise reduction brake block steel back, this noise reduction brake block steel back includes that body carried on the back by steel, steel back of the body body is provided with no less than 12 noise reduction holes, minimum spacing between the edge in any two noise reduction hole is not less than 5mm, and 1-1.2 times of the thickness that the minimum dimension in noise reduction hole is steel back of the body body.Based on this kind of design, according to sound diffraction principle, when noise is by brake block steel back, noise intensity can be weakened by noise reduction hole, thus reduce the purpose of noise.Further, in noise reduction brake block steel back with friction material adhesion process, friction material can be filled in noise reduction hole, therefore adds friction material and the degree of adhesion of noise reduction brake block steel back, thus enhances the shear strength of brake block.
The preferably circular through hole in described noise reduction hole, to facilitate processing.The diameter of this manhole can be 1.1 times of the thickness of steel back of the body body.However, it is to be understood that described noise reduction hole can be the hole of any shape, such as polygon, slotted eye etc..
The fabrication hole for playing the role of positioning during steel back of the body body processing it is also provided with on steel back of the body body.Preferably, fabrication hole is symmetrically distributed in the central axis x-x both sides of steel back of the body body, and noise reduction orifice ring winding technologe hole is uniformly distributed.Certainly, steel back of the body body also can not set fabrication hole.In this case, noise reduction hole can be evenly distributed on steel back of the body body.Being uniformly distributed of noise reduction hole 3, it is possible to achieve preferably noise reduction.
This utility model additionally provides a kind of brake block, and this brake block includes above-mentioned noise reduction brake block steel back and is bonded in the friction material on this noise reduction brake block steel back.
Accompanying drawing explanation
By non-limiting example, this utility model is described in detail with reference to the accompanying drawings, wherein:
Fig. 1 is the structural representation of this utility model noise reduction brake block steel back.
In figure, 1, steel back of the body body, 2, fabrication hole, 3, noise reduction hole.
Detailed description of the invention
Describe the noise reduction brake block steel back of this utility model embodiment with reference to the accompanying drawings and include the brake block of this noise reduction brake block steel back.In the following description, elaborate that many details are to enable person of ordinary skill in the field to be best understood from this utility model.But, it is evident that realization of the present utility model can not have some in these details for the technical staff in art.However, it should be understood that this utility model is not limited to introduced specific embodiment.Therefore, the following examples and advantage are used for illustrative purposes only, and are not construed as limitations on the claims, unless the most clearly proposed.
As it is shown in figure 1, noise reduction brake block steel back of the present utility model includes that body 1 carried on the back by steel, steel back of the body body 1 is provided with 32 noise reduction holes 3 and for 2 fabrication holes 2 of positioning action during processing.Wherein 2 fabrication holes 2 are manhole, are evenly distributed on the central axis x-x both sides of steel back of the body body 1；32 noise reduction holes 3 are also round shape through hole, are uniformly distributed around fabrication hole 2.And, the minimum spacing between the edge in any two noise reduction hole 3 is 5mm, 1.1 times of the thickness of a diameter of steel back of the body body 1 in noise reduction hole 3.
Certainly, can not also set the fabrication hole 2 for positioning action in this utility model on steel back of the body body 1, in this case, noise reduction hole 3 can be evenly distributed on steel back of the body body 1.Additionally, noise reduction hole 3 can also be the hole of any shape, such as square hole, hexagonal hole, slotted eye etc., the minimum dimension in these noise reduction holes is 1-1.2 times of the thickness of steel back of the body body 1, and the minimum spacing between the edge in any two noise reduction hole 3 is not less than 5mm, the quantity in noise reduction hole 3 need to meet no less than 12.Can be different according to minimum spacing between the difference of brake block steel back size, the quantity in noise reduction hole 3 and the edge in any two noise reduction hole 3, on the premise of meeting above-mentioned requirements, can be adjusted reaching optimum anti-acoustic capability.
This utility model also provides for a kind of brake block, and this brake block includes above-mentioned noise reduction brake block steel back and is bonded in the friction material on this noise reduction brake block steel back.When described noise reduction brake block steel back is used in brake block, friction material can be bonded on noise reduction brake block steel back, in adhesion process, friction material can be filled in noise reduction hole 3 and fabrication hole 2, thus increase the degree of adhesion of brake block steel back and friction material, and then the shear strength of enhancing brake block, improve brake safe.When braking, brake noise can occur sound diffraction by noise reduction hole 3, so that the strength reduction of brake noise, reaches the effect of noise reduction.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
