Description
Technical field
The utility model relates to a kind of powder metallurgy friction piece assembly for brake pad, belongs to powder metallurgical technology.
Background technique
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, and suitable and stable friction factor, stable working is reliable, the advantage such as have higher thermal capacity and heat-conductive characteristic, wear resistance good, applies more extensive in friction material.
Due to one of vitals that brake lining is train braking device, directly have influence on the security of operation of train, train is when braking, kinetic transformation is heat energy and is dispersed into rapidly in air by brake lining, therefore require that brake lining friction material not only will have good friction and wear behavior, also should have good heat-conductive characteristic.In addition, current existing brake lining majority is integrated type, without floating, non-exchange.Also some brake lining friction piece needs for installation, and center portion band is porose, but abrasive dust will be stored in this hole in braking process, and in the severse weather such as sleet, sand and dust, abrasive dust easily forms mud, and formation damascene causes the damage to brake disc.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of powder metallurgy friction piece assembly for brake pad.Can to be connected to independently on brake pad and heat-conducting property well, not easy damaged brake disc.
For achieving the above object, the utility model takes following technological scheme: a kind of powder metallurgy friction piece assembly for brake pad, it is characterized in that: it comprises a frame board, the middle part of described frame board is upwards swelled, described bump upper, lower surface forms outer spherical supporting surface and interior spherical respectively, a pin is worn at the center of described frame board, the bottom of described pin is provided with a spherical matched with described interior spherical, jointly being connected a cross section in described frame board and the bottom of described pin is orthohexagonal brake pad, described brake pad is provided with a center hole, a heating column is plugged in described center hole, described heating column and described pin bottom just right, described frame board, described pin, described brake pad and described heating column are sintered into one.
Circumference along described frame board is arranged at intervals with plural positioning hole and plural material grasping hole, and the both sides that described brake pad is positioned at described center hole are respectively arranged with the positioning boss matched with described positioning hole.
Described frame board adopts structural carbon steel, and the surface of described frame board is coated with one deck copper film.
A draw-in groove is offered on the top of described pin.
The utility model is owing to taking above technological scheme, it has the following advantages: 1, the utility model is owing to being provided with a frame board, the middle part of frame board is upwards swelled, the upper and lower surface of bump forms outer spherical supporting surface and interior spherical respectively, play regulating action when brake pad connects, what make to fit when brake pad of the present utility model and brake disc is tightr, and the utility model has independence, and can change, the utility model novel structure, Economy are high.2, the utility model is owing to being provided with a heat-conducting block at the center of brake pad, heat energy can be absorbed rapidly when braking, the steel backing transferring heat energy to brake pad is dispersed in air, reduce brake disc temperature, reduce brake disc damage or damascene phenomenon, not easy damaged brake disc when brake pad is braked under high and cold sleet severe weather conditions.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 1 and Figure 2, the utility model proposes a kind of powder metallurgy friction piece assembly for brake pad, it comprises a frame board 1, the middle part of frame board 1 is upwards swelled, the upper and lower surface of bump forms outer spherical supporting surface 11 and interior spherical 12 (as shown in Figure 3, Figure 4) respectively, wear a pin 2 at the center of frame board 1, the bottom of pin 2 is provided with a spherical matched with interior spherical 12.Jointly being connected a cross section in frame board 1 and the bottom of pin 2 is orthohexagonal brake pad 3, brake pad 3 is provided with a center hole 31 (as shown in Figure 5, Figure 6), plugs a heating column 4 in center hole 31, and heating column 4 is just right with pin 2 bottom.Frame board 1, pin 2, brake pad 3 and heating column 4 are sintered into one.
In above-described embodiment, the circumference along frame board 1 is arranged at intervals with plural positioning hole 13 and plural material grasping hole 14, and the both sides that brake pad 3 is positioned at center hole 31 are respectively arranged with the positioning boss 32 matched with positioning hole 13.
In above-described embodiment, frame board 1 adopts structural carbon steel, is coated with one deck copper film in its surface.
In above-described embodiment, offer a draw-in groove 21 on the top of pin 2.
As shown in Figure 1, when the utility model uses, multiple the utility model is arranged in brake pad steel backing (not shown) respectively by an elastic supporting part (not shown), and is fixed on brake lining steel backing by a location card (not shown) be set on pin 2 draw-in groove 21.During braking, retardation pressure to act on brake pad of the present utility model on 3, and multiple brake pad 3 steadily laminating brake disc (not shown) implements braking.Universal regulated can be carried out to the height of brake pad 3 under the effect of dish-shaped shell fragment, increase brake pad 3 and the friction area of brake disc, reduce rubbing surface eccentric wear phenomenon, thus in braking process, obtain maximum effective contact friction area.The kinetic energy that brake lining absorbs is converted to rapidly heat energy to be transmitted on brake lining steel backing by brake pad 3, heating column 4 and to be dispersed in air simultaneously, avoids damascene and reduce the damage of brake disc.
