Abstract
The utility model relates to a powder metallurgy brake-shoe, comprising an arc steel back (1), wherein the middle position outside the arc of the steel back (1) is provided with a latch pin button (3); two sides of the latch pin button (3) are symmetrically provided with two latch pin positioning grooves (4); friction material blocks (2) molded with metal powder are sintered on the arc inner surface of the steel back (1). Compared with the prior art, the brake-shoe is simple in structure, convenient to manufacture and low in cost.
Description
The utility model relates to a kind of powder metallurgy brake block.
Brake shoe is a kind of parts that are used for railway locomotive, car brakeing.The brake shoe that tradition is used has three types, i.e. cast iron brake shoe, composite brake shoe and powder metallurgy brake block.Cast iron brake shoe is the brake shoe of being made by middle phosphorus cast iron or high squama cast iron, composite brake shoe is to be the brake shoe that main warp hot pressing forms with materials such as resin, asbestos, graphite, iron powder, barium sulphate, and powder metallurgy brake block is to be matrix, additional one or more other metals and nonmetal composition and the brake shoe that forms by mixing, compacting and sintering with the metal.Contain squama cast iron brake shoe weight big, use noise height, big to taking turns right wearing and tearing, composite brake shoe contains asbestos component, its heat dispersion is poor, and environment is had pollution.At present, cast iron brake shoe and composite brake shoe generally can only be used for the locomotive that speed per hour is lower than 120km, and working life is shorter.Raising along with locomotive speed, to the brake shoe demands for higher performance, promptly require brake shoe not only to have good braking ability, and require the braking antithesis---irregular wear and damage do not produced, adhesion between wheel, rail is not produced injurious effects, free from environmental pollution, powder metallurgy brake block then can satisfy above-mentioned requirements.Chinese patent ZL97215240.7 discloses a kind of powder metallurgy brake block, it comprises big steel backing and friction material block, friction material block is three, and it is made of little steel backing and the pressure sintering metallic dust friction material on it, and described friction material block is riveted on the big steel backing.It adopts two-layer steel backing this patented technology, and it is to make friction material block by little steel backing and friction material earlier, and then little steel backing is riveted on the big steel backing, thus this brake shoe structure and manufacturing process complexity, the cost height.
The purpose of this utility model is exactly the above-mentioned deficiency that overcomes prior art, and the brake shoe that a kind of structure and manufacturing process are simple, cost of production is low is provided.
Powder metallurgy brake block of the present utility model comprises an arc steel backing, intermediate portion outside the arc of steel backing is provided with bolt buckle, and the both sides at bolt buckle are provided with the latch positioning groove symmetrically, at the inner face direct sintering of steel backing arc friction material block by the metallic dust moulding are arranged.
Compare the utility model brake shoe simple in structure, easily manufactured with prior art, cost is low, and its use individual layer steel backing also can satisfy the requirement of car brakeing, and has more performance than cast iron brake shoe and composite brake shoe, its mechanical strength height, good heat resistance, wear-resisting and heat resistanceheat resistant decline function admirable, long service life, little to taking turns right wearing and tearing, stable friction performance, brake noise is low, pollution is little, applicable to the braking of the locomotive more than the speed per hour 160km.
Describe the utility model in detail with embodiment with reference to the accompanying drawings.
Accompanying drawing 1 is the plan view of the utility model brake shoe;
Accompanying drawing 2 is plan views of Fig. 1 brake shoe;
Accompanying drawing 3 is the sectional views along Fig. 2 brake shoe A-A line.
As shown in the figure, powder metallurgy brake block of the present utility model comprises an arc steel backing 1, intermediate portion outside the arc of steel backing 1 is provided with bolt buckle 3, and the bilateral symmetry of bolt buckle 3 be provided with latch positioning groove 4, at the inner face direct sintering of steel backing 1 arc friction material block 2 by the metallic dust moulding is arranged.
Evidence, the utility model uses the brake shoe of individual layer steel backing also can satisfy the requirement of car brakeing fully, and has more performance than cast iron brake shoe and composite brake shoe, its mechanical strength height, good heat resistance, wear-resisting and heat resistanceheat resistant decline function admirable, long service life, little to taking turns right wearing and tearing, stable friction performance, brake noise is low, pollution is little, applicable to the braking of the locomotive more than the speed per hour 160km.
Described friction material block 2 is the 2-6 piece, is preferably three or four, spaced set.The advantage of friction material block polylith spaced set is a rapid heat dissipation when saving material, braking, improves heat resistanceheat resistant decline performance, thereby improves working life.
Described steel backing 1 has the brake pad position structure at the position that it is connected with friction material block 2.The purpose that position structure is set is to make between steel backing 1 and the friction material block 2 accurately to locate when sintering, easy-to-operat, and improve yield rate.
In a preferred structure of the present utility model, described brake pad position structure is and described each friction material block 2 corresponding groove 5 that friction material block 2 is separately positioned in each groove 5 and has the structure that adapts with groove 5.Friction material block is arranged on can also assist in the groove strengthens itself and the fixedlying connected of steel backing 1.
Described groove can be stepped shaft.
In another embodiment of the present utility model, can be provided with auxiliary reinforcer (not shown) between described friction material block 2 and the steel backing 1, this reinforcer is fixedlyed connected with described steel backing 1, plays a part to strengthen connecting between friction material block 2 and the steel backing 1.Should auxiliary reinforcer can be the projection that is fixed in the steel backing 1 described groove, also can be the built-in steel plate (bar) that passes the whole height of friction material block, can also be the boots shape reinforcer that is provided with around friction material block.
Above-mentioned description with reference to drawings and Examples is just illustrative, and does not constitute qualification of the present utility model.Obviously, on basis of the present utility model, can carry out many modification, but not break away from its essence.
