Abstract
The invention discloses a brake pad which comprises a steel framed structure and a plurality of friction material blocks, the friction material blocks are fixed onto the steel framed structure, an arc groove is arranged on the surface of every friction material block, and both ends of every arc groove are arranged close to the adjacent friction material block. According to the brake pad, the arc grooves are arranged on the surfaces of the friction material blocks so as to effectively discharge dust generated by friction materials without affecting the normal use of the friction materials, and good heat dissipation effect and long service life can be obtained.
Description
Technical field
The present invention relates to auto parts machinery technical field, especially a kind of brake block.
Background technique
Brake block is vitals in car deceleration equipment, all generally to adopt fixed friction material layer on steel frame construction, easy sedimentating dust on brake block in use, dust accumulation has reduced the friction factor of brake block, noise is larger, and in use, on brake block, the thickness of friction layer has certain requirement simultaneously, the too thin sensitivity that can affect brake, has reduced Safety performance.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of brake block, structure is ingenious, and noise is little.
In order to realize foregoing invention object, the invention provides following technological scheme: a kind of brake block, comprise steel frame construction and friction material block, this friction material block is fixed on steel frame construction, described friction material block is provided with several, and the rubbing surface of each friction material block is provided with curve bath; The two ends of this curve bath are located near adjacent friction material block.
Further, described friction material block is provided with 4 to 8, is uniformly distributed.
Further, described friction material block is made by following material: butyl butylbenzene 1-10 part, hydrogen phosphide cumene 0.5-2 part, epoxy resin 0.5-2 part, boron bakelite resin 1-15 part, polypropylene 1-15 part, dicumyl peroxide 1-5 part, graphite 30-50 part, reducing iron powder 1-2 part, barium sulphate 1-2 part, alum earth 0.5-2 part, feldspar powder 0.5-2 part, zine oxide 0.5-2 part.
Compared with prior art, the present invention has the following advantages: on the rubbing surface of friction material block, curve bath is set, can effectively discharges the dust that friction material produces, do not affect again the normal use of friction material; Good heat dissipation effect, long service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, describe the present invention, the description of this part is only exemplary and explanatory, should not have any restriction to protection scope of the present invention.
A kind of brake block as shown in Figure 1, comprises steel frame construction 1 and 6 friction material blocks 2, and these 6 friction material blocks 2 are evenly fixed on steel frame construction 1, the curve bath 21 that the rubbing surface of described friction material block 2 is provided with.The two ends of this curve bath 21 are located near adjacent friction material block 2.In brake pad rotary course, fricative dust can enter in this curve bath 21, because curve bath 21 is oblique setting, can effectively collect all dust, has improved the using effect of friction layer.Fricative heat also can be discharged through this curve bath 21 simultaneously, and arc setting can make Air Flow smooth and easy, good heat dissipation effect.
Described friction material block 2 is made by following material: butyl butylbenzene 1-10 part, hydrogen phosphide cumene 0.5-2 part, epoxy resin 0.5-2 part, boron bakelite resin 1-15 part, polypropylene 1-15 part, dicumyl peroxide 1-5 part, graphite 30-50 part, reducing iron powder 1-2 part, barium sulphate 1-2 part, alum earth 0.5-2 part, feldspar powder 0.5-2 part, zine oxide 0.5-2 part.
Mix above-mentioned material, carry out hot-formingly in mould, pilot pressure is 50-100MPa(500-1000kg/cm
2), hot pressing time 4～6 minutes; Usual manner sulfuration, then bonds with steel frame construction.
Adopt graphite to replace traditional asbestos, have heat-conductive characteristic good, during braking, temperature rise is low; And greatly reduce the cost of brake block, and can effectively improve the wear-resisting property of brake block, and there is good heat dispersion.Therefore, wear-resisting, long service life that the present invention has realized, no-spark, odorlessness, noise are little, the advantage of perfect heat-dissipating; When 300 kilometers of speed per hours or above Emergency braking, (as motor-car etc.) still can keep brake block temperature at 190 ℃, thereby brake block integral body is not yielding, have no irritating odor.And, due to a large amount of uses of graphite, make brake block obtain wear-resisting property and greatly promote, and be difficult for to produce spark, noise is little.
