Abstract
The utility model discloses a brake pad which comprises a substrate. One side of the substrate is provided with a friction plate; the other side of the substrate is provided with a mounting block; the position of the center symmetric line of the friction plate is provided with a groove; the groove has a depth of 8mm and a width of 4mm. According to the utility model, by forming the groove with a certain depth and width at the position of the center symmetric line of the friction plate, heat dissipation performance of a friction material can be improved in the braking process; the brake pad is convenient to clean up grinding dust generated in the braking process and accelerate updating of a surface layer of the friction material, so that friction performance of the friction material further tends to be more stable; vibration frequency of the friction plate is changed and brake noise in the braking process is reduced.
Description
Technical field
The utility model relates to a kind of auto parts machinery, particularly a kind of brake block.
Background technique
At present, the fluting measure has all been adopted in the design of the supporting brake block of most of main frames, but then still keep original design mostly for some designs brake block relatively early, be that great majority all do not have fluting, but and do not mean that the product of not slotting necessarily has brake noise, this is because brake noise not exclusively is to be caused by friction material also, brake disc and friction plate are in mutual extrusion from the process that initially touches comprehensive engagement, deformation takes place in the capital, vibrates according to natural frequency separately then, when the two vibration frequency is identical, vibration is strengthened, produce the probability of brake noise just than higher, on the contrary vibration weakening, and the probability that produces brake noise can reduce.In addition, fluting can also play deashing, thermolysis, improves the problem that braking force descends under the different braking condition, but, unsuitable groove depth does not only have the effect that reduces brake noise, also may cause steel backing distortion even friction plate fracture, and vehicle safe driving is threatened.
The model utility content
For solving the problems of the technologies described above, the utility model provides a kind of brake block, with the vibration frequency that changes friction plate to reach the purpose that reduces noise.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of brake block comprises substrate, and a side of described substrate is equipped with friction plate, and the opposite side of described substrate is provided with mounting blocks, and the centre symmetry line position of described friction plate has groove, and the degree of depth of described groove is 8 millimeters, and width is 4 millimeters.
By technique scheme, a kind of brake block that the utility model provides, it has following advantage by open the groove of certain depth and width at the centre symmetry line place of friction plate in braking process:
1. fluting can improve the friction material heat dispersion, can improve the friction material thermal characteristics;
2. clear up the grinding dust that produces in the braking process, accelerate the friction material surface layer and upgrade, make the friction material frictional behaviour more stable;
3. change the friction plate vibration frequency, reduce the brake noise in the braking process.
Description of drawings
In order to be illustrated more clearly in the technological scheme among the utility model embodiment, the accompanying drawing of required use is done to introduce simply in will describing embodiment below.
Fig. 1 is the plan structure schematic representation of the disclosed a kind of brake block of the utility model embodiment;
Fig. 2 is the side-looking structural representation of Fig. 1.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described.
With reference to figure 1 and 2, the brake block that the utility model provides comprises substrate 11, one side of substrate 11 is equipped with friction plate 12, and the opposite side of substrate 11 is provided with mounting blocks, and the centre symmetry line position of friction plate 12 has groove 13, the degree of depth of groove 13 is 8 millimeters, and width is 4 millimeters.
A kind of brake block that the utility model provides, it opens the groove 13 of certain depth and width by the centre symmetry line place at friction plate 12, and in braking process, groove 13 can improve the friction material heat dispersion, can improve the friction material thermal characteristics; Groove 13 is conducive to clear up the grinding dust that produces in the braking process, accelerates the friction material surface layer and upgrades, and makes the friction material frictional behaviour more stable; The groove 13 of certain depth and width can change the friction plate vibration frequency, reduces the brake noise in the braking process.
Multiple modification to above-described embodiment will be apparent concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments herein.
