Abstract
A kind of novel high speed brake disc, comprise circular disk body, hole centered by the centre of disk body, the front-end face of disk body and ear end face are friction catch face, friction catch face is processed with marking groove I, marking groove I runs through the radial direction in friction catch face, and friction catch face is also processed with marking groove II, marking groove II is arranged in a crossed manner with marking groove I, and the degree of depth of marking groove II is greater than the degree of depth of marking groove I.The utility model has that friction catch is effective, frictional force is large, the degree of wear is easy to judge, the advantage that cost is low.
Description
Technical field
The utility model relates to skidding technical field, especially relates to a kind of novel high speed brake disc.
Background technique
Dish braking is the one of skidding, in dish braking, main brake part is brake disc, clamp brake disc by brake caliper and then produce braking force, therefore when skidding, it is the key wear of brake disc that the braking surface that clamp cause in contacting with brake disc brake lining weares and teares, once may wear to a certain degree, brake disc must be changed.
In conventional art, whether general the replacing of brake disc is uses mileage number to determine according to this dish, although this kind of determination methods is simple to operate, because the operating habit of automobile running environment and driver is all not identical, therefore ubiquity brake disc changes situation improperly.
Application number is disclose a kind of brake disc in the application for a patent for invention of 201410168989.7, the inside and outside friction operation surface of this dish is uniformly distributed along disc rotation direction organizes marking groove more, radiation hole is provided with between two between marking groove, marking groove radial direction covers fricting working surface, the dark 0.2-0.5mm of wear limit of marking groove depth ratio brake disc.Patent application of the present invention by processing the mode of marking groove, radiation hole on brake disc working surface, effectively reduce the problems such as the character of heat-fading of break, water fade and brake noise, but do not consider that the abrasion condition of groove of another purposes of marking groove-to the layout line judges that brake disc needs whether to change fast.
Summary of the invention
The purpose of this utility model is to provide a kind of novel brake disc, this dish friction catch face is processed with two kinds of marking groove that the degree of depth is different, while significantly increasing braking friction, also can according to the degree of wear of different depth marking groove, fast, accurate judgement brake disc is the need of replacing, the technological scheme adopted is: a kind of novel high speed brake disc, comprise circular disk body, hole centered by the centre of described disk body, the front-end face of described disk body and ear end face are friction catch face, it is characterized in that: described friction catch face is processed with marking groove I, described marking groove I runs through the radial direction in described friction catch face, described friction catch face is also processed with marking groove II, described marking groove II is arranged in a crossed manner with described marking groove I, and the degree of depth of marking groove II is greater than the degree of depth of marking groove I.
Technical characteristics of the present utility model also has: described marking groove I and marking groove II are curve.
Technical characteristics of the present utility model also has: the length of described marking groove II is less than the length of marking groove I.
Technical characteristics of the present utility model also has: described marking groove II 0.5mm darker in marking groove I.
Technical characteristics of the present utility model also has: the degree of depth of described marking groove I is 1mm.
The beneficial effects of the utility model are: be braked dish by being arranged on the marking groove that on rubbing surface, two kinds of degree of depth are different, not only can remove the dust produced in braking in time and then significantly increase friction brake force, and all worn away when braking surface may wear to shallow marking groove, now namely brake disc should be changed, wear mark is clear, obviously, judgment accuracy is high, overcome in prior art the error needing to be indicated by cylindrical or exist in distance travelled number deterministic process large, the disadvantage of complicated operation, there is friction catch effective, frictional force is large, the degree of wear is easy to judge, the advantage that cost is low.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model plan view, and accompanying drawing 2 is side views of accompanying drawing 1, and wherein, 1 is circular disk body, and 2 is center holes, and 3 is pilot holes, and 4 is marking groove I, and 5 is marking groove II.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.The utility model discloses a kind of novel high speed brake disc, this brake disc comprises circular disk body 1, hole 2 centered by the centre of circular disk body 1, the front-end face of circular disk body 1 and ear end face are friction catch face, friction catch face is processed with marking groove I 4 and marking groove II 5, marking groove I 4 runs through the radial direction in friction catch face, and marking groove II 5 is arranged in a crossed manner with marking groove I 4, and the degree of depth of marking groove II 5 is greater than the degree of depth of marking groove I 4.
In present embodiment, the length of marking groove II 5 is less than the length of marking groove I 4.
In present embodiment, for the purpose of attractive in appearance, marking groove I 4 and marking groove II 5 are all arranged to curve, and the degree of crook of marking groove II 5 is obviously greater than the degree of crook of marking groove I 4.
In present embodiment, after marking groove I 4 and marking groove II 5 combine, form Leaves'Shape.
In order to reach the object that wearing and tearing judge, the degree of depth of marking groove I 4 is 1mm, marking groove II 5 0.5mm darker in marking groove I.Like this, when marking groove I 4 is worn away completely, illustrate that namely brake disc should be changed.
Certainly; above-mentioned explanation is not limitation of the utility model; the utility model is also not limited only to above-mentioned citing, the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also belongs to protection domain of the present utility model.
