Along with improving constantly of train speed, brake load is increasing, also more and more higher to the requirement of strength of brake pad.At present, powder metallurgy brake pad friction material is because having enough intensity, suitable and stable coefficient of friction, stable workingReliably, have the advantages such as higher thermal capacity and heat-conductive characteristic, wearability are good, in friction material, application is more extensive.
Be one of vitals of train braking device due to brake lining, directly have influence on the security of operation of train, train existsWhen braking, brake lining is heat energy by kinetic transformation and is dispersed into rapidly in air, therefore requires brake lining friction material not only to wantThere is good friction and wear behavior, also should there is good heat-conductive characteristic. But existing brake disc is at high height above sea levelWith but cisco unity malfunction under sub-zero adverse circumstances. In addition, existing brake lining majority is monoblock type, without floating,Non-exchange. Some brake lining friction piece needs for installing, and centre band is porose, but this hole is in braking procedureTo store abrasive dust, in the bad weather such as sleet, sand and dust, abrasive dust easily forms mud, forms damascene and causes systemThe damage of Moving plate.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of powder metallurgy friction piece assembly for brake pad.Can be connected to independently on brake pad and heat conductivility well, easy damaged brake disc not, and can make brake disc existUnder high height above sea level and sub-zero adverse circumstances, normally work.
For achieving the above object, the present invention takes following technical scheme: a kind of powder metallurgy friction for brake padBody assembly, is characterized in that: it comprises a frame board, and upwards swell at the middle part of described frame board, described bumpUpper and lower surface form respectively outer spherical supporting surface and interior spherical, wear a pin at the center of described frame boardNail, the bottom of described pin is provided with a spherical matching with described interior spherical, at described skeletonBeing connected a cross section is orthohexagonal brake pad jointly in the bottom of plate and described pin, on described brake pad, is provided with oneCentre bore plugs a heating column in described centre bore, and described heating column and described pin bottom are just right, described skeletonPlate, described pin, described brake pad and described heating column are sintered into one.
Described heating column is made up of copper and graphite, and the content of copper is 60～70%, and the content of graphite is 30～40%.
Along described frame board be circumferentially arranged at intervals with plural locating hole and plural material grasping hole, describedThe both sides that are positioned at described centre bore on brake pad are respectively arranged with the positioning boss matching with described locating hole.
Described frame board adopts carbon structural steels, is coated with one deck copper film on the surface of described frame board.
Offer a draw-in groove on the top of described pin.
The present invention is owing to taking above technical scheme, and it has the following advantages: 1, the present invention is owing to being provided with a frame board,Upwards swell at the middle part of frame board, and the upper and lower surface of bump forms respectively outer spherical supporting surface and interior spherical supportFace plays regulating action in the time that brake pad connects, and when brake pad of the present invention is contacted with brake disc, laminating is tighterClose, the present invention has independence, and can change, and novel structure of the present invention, economy are high. 2, the present invention due toThe center of brake pad is provided with a heating column, and heating column is made up of copper and graphite, and the content of copper is 60～70%, graphiteContent be 30～40%, time can absorb rapidly heat energy in braking, transfer heat energy on the steel backing of brake pad alsoBe dispersed in air, reduce brake disc temperature, reduce brake disc damage or damascene phenomenon, therefore can make brakingEasy damaged brake disc not when brake lining is braked under high and cold subzero, high height above sea level and sleet severe weather conditions.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in detail.
As shown in Figure 1 and Figure 2, the present invention proposes a kind of powder metallurgy friction piece assembly for brake pad, itComprise a frame board 1, upwards swell at the middle part of frame board 1, and the upper and lower surface of bump forms respectively outer sphericalSupporting surface 11 and interior spherical 12 (as shown in Figure 3, Figure 4), wear a pin 2 at the center of frame board 1,The bottom of pin 2 is provided with a spherical matching with interior spherical 12. At frame board 1 and pin 2The common cross section that connects, bottom be orthohexagonal brake pad 3, on brake pad 3, be provided with a centre bore 31 (asShown in Fig. 5, Fig. 6), in centre bore 31, plug a heating column 4, heating column 4 is just right with pin 2 bottoms. SkeletonPlate 1, pin 2, brake pad 3 and heating column 4 are sintered into one.
In above-described embodiment, heating column 4 is made up of copper and graphite. Wherein, the content of copper is 60～70%, graphiteContent is 30～40%, makes heating column 4 have higher heat-conductive characteristic.
In above-described embodiment, along the plural locating hole 13 of being circumferentially arranged at intervals with of frame board 1 and pluralMaterial grasping hole 14, the both sides that are positioned at centre bore 31 on brake pad 3 are respectively arranged with the location of matching with locating hole 13Boss 32.
In above-described embodiment, frame board 1 adopts carbon structural steels, is coated with in its surface one deck copper film.
