The technical problems to be solved in the utility model is realized using following technical scheme: a kind of brake pad and brake disc
Gap detection feeler gauge, including drift and no-go gage, the drift and no-go gage are zigzag structure, and the drift and no-go gage wrap
Including the portion of filling in, interconnecting piece and handle, the cross section for filling in portion is rectangle, it is described to fill in portion and handle is arranged in parallel, it is described
The both ends of interconnecting piece are connect with the portion that fills in and handle respectively, and the wall thickness of the no-go gage is greater than the wall thickness of drift, the end of the no-go gage
Portion is equipped with cone angle.
Preferably, it is 4mm that the no-go gage, which fills in the wall thickness in portion, and the wall thickness that drift fills in portion is 2mm, and the drift is filled in
It is 200mm that portion and no-go gage, which fill in the width in portion,.
Preferably, the upper surface that no-go gage fills in portion is arranged in the end cone angle of the no-go gage, and the angle of the cone angle is
0.5°。
Preferably, multiple weight loss grooves are equipped on the drift and no-go gage.
Preferably, the weight loss groove is circle.
Preferably, the interconnecting piece is arranged perpendicular to the portion that fills in and handle.
Preferably, be hinged with pin shaft between the drift and no-go gage, the both ends of the pin shaft respectively with the handle of drift
It is hinged with the handle of no-go gage.
Preferably, the two sides for filling in portion are equipped with circular arc guide margin, and the radius of the circular arc guide margin is greater than 800mm.
Compared with prior art, the utility model has the beneficial effects that changing the 2mm ruler and two used in the prior art
The detection mode of a 2mm ruler superposition, is used in combination, detection effect is accurate and reliable, especially detector gap using drift and no-go gage
When between 2 ~ 4mm, it is more convenient, is more efficient, and the gap of the width of drift and no-go gage and brake unit brake lining and brake disc
Similar width, drift or no-go gage are once inserted into the detection that can be achieved within the scope of entire gap width, avoid because of detection ruler
It can't detect position when width is narrow and the consuming time be excessive, offer weight loss groove on drift and no-go gage, guaranteeing structural strength
The weight of drift and no-go gage is largely reduced simultaneously.
Detailed description of the invention
Fig. 1 is the drift structural schematic diagram of the utility model embodiment.
Fig. 2 is the no-go gage structural schematic diagram of the utility model embodiment.
Fig. 3 is the brake unit brake lining of the utility model and the structure top view of brake disc.
Marked in the figure: 1- brake pad, 2- brake disc, 3- weight loss groove.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, with reference to the accompanying drawing and specifically
The utility model is described in detail in embodiment.It should be appreciated that specific embodiment described herein is only used to explain this
Utility model is not used to limit the utility model.
As depicted in figs. 1 and 2, the gap detection feeler gauge of a kind of brake pad and brake disc, including drift and no-go gage, it is described
Drift and no-go gage are all made of stainless steel (06Cr19Ni10) material and are made, and the drift and no-go gage can be separated and be used alone,
Pin shaft can be provided between drift and no-go gage, the both ends of the pin shaft are hinged with the handle of the handle of drift and no-go gage respectively,
So that being relatively rotatable to each other between drift and no-go gage, increase the portability of drift and no-go gage, the drift and no-go gage include plug
Entering portion, interconnecting piece and handle, the cross section for filling in portion is rectangle, it fills in portion and handle is arranged in parallel, the connection
Portion is connected between the portion of filling in and handle, and interconnecting piece not only acts as connection plug perpendicular to portion and handle, the interconnecting piece is filled in
Enter the effect of portion and handle, moreover it is possible to play the role of limit when detecting the gap between brake pad 1 and brake disc 2.
Drift fill in portion and no-go gage to fill in the width in portion be 200mm, the drift fills in portion and no-go gage fills in the width in portion
The width close to gap between brake pad 1 and brake disc 2 is spent, can be reduced because filling in portion's short of width, when detection needs
The workload of double swerve saves the time.Drift fill in portion with a thickness of 2mm, no-go gage fill in portion with a thickness of 4mm, drift plug
Enter portion and no-go gage fills in the top in portion and is equipped with weight loss groove 3, the weight loss groove 3 is circular through hole, and circular weight loss groove can be
While portion's own wt is filled in mitigation, avoid filling in portion by generation stress is concentrated at weight loss groove when external force.No-go gage plug
The end for entering portion is equipped with cone angle, and the upper surface that no-go gage fills in portion is arranged in the cone angle, and the angle of cone angle is 0.5 °, passes through the cone
Angle can be inserted into the effect in gap between brake pad 1 and brake disc 2, the two sides for filling in portion convenient for the portion that fills in of no-go gage
It can be also equipped with arc-shaped guide margin, the radius of the circular arc guide margin is not less than 800mm, can using the rounded leading edge for filling in portion two sides
Portion and brake pad 1 are filled in reduction and brake disc 2 is collided, and prevent from blocking drift or no-go gage, save detection time.The present embodiment
The shape of middle interconnecting piece and handle with fill in that portion is identical, and the weight loss groove of rectangle is also equipped on handle, the handle may be used also
It is convenient for taking the cylinder held to be made into.
When detecting the gap between brake pad 1 and brake disc 2, according to production and use need the gap 2mm ~
It is qualified gap between 4mm, the gap first is detected into the drift portion of filling in of 2mm thickness, if drift is filled in portion and can not be passed through,
Then the gap does not meet production requirement；If drift is filled in portion and can be passed through, illustrates that the gap meets and be more than or equal between 2mm
Gap requirement, is further detected using no-go gage, if no-go gage is filled in portion and can be crossed and passes through the gap, illustrates that the gap is not met
Production requirement, if no-go gage fill in portion can not by the gap if illustrate that the product meets the design production requirement of 2mm ~ 4mm, be
Qualified products.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, and should refer to
Out, any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention etc. should all include
It is within the protection scope of the utility model.
