Abstract
The invention discloses a brake pad which comprises a steel frame structure and a friction material layer fixed on the steel frame structure. An arc groove 3mm in depth is formed in the friction face of the friction material layer. Due to the fact that the arc groove is formed in the friction face of the friction material layer, dust produced by the friction material can be effectively discharged, and normal use of the friction material is not affected. The brake pad is good in radiating effect and long in service life.
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 layer, this friction material layer is fixed on steel frame construction, and the rubbing surface of described friction material layer is provided with the curve bath that 3mm is dark.
Further, the cecum of described curve bath is located at friction material layer middle part, and opening end is located at the outside of described friction material layer.
Further, described friction material layer 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 layer, 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 friction material layer 2, and this friction material layer 2 is fixed on steel frame construction 1, and the rubbing surface of described friction material layer 2 is provided with the curve bath 21 that 3mm is dark.The two ends of this curve bath 21 connect respectively the both sides of described friction material layer 2.In use, 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 layer 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/cm2), 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.
