Abstract
The utility model relates to a brake shoe which comprises a framework (1), friction material blocks (4), bolt buckles (5) and bolt positioning grooves (2), wherein the bolt buckles (5) are welded on the middle of the upper part of the framework (1), and the bolt positioning grooves (2) are welded away from the middle at the equidistance. The utility model is characterized in that the utility model is also provided with steel back (3); copper and iron powder metal is pressurized and sintered on the steel back (3) to serve as the friction material blocks (4); the three friction material blocks (4) are mechanically riveted with the framework (1) by rivets (6). Compared with cast iron brake shoes containing phosphorus and composite brake shoes, the utility model has the advantages of long service life, small wear on wheel pairs, no noise in brake, no pollution, etc. The utility model is suitable for locomotives with the speed of 160 to 180 kilometers per hour.
Description
The utility model belongs to accessory in the running mechanism of train device, refers in particular to brake shoe.
When brake shoe is railway locomotive, car brakeing, be pressed on the wheel tread to produce the slipper of brake action.According to GB4549.2-84 " rolling stock noun running gear " standard, China has three kinds of brake shoes at present, is made up of friction material block and skeleton, or is the monoblock friction material block, and bolt buckle and latch detent are arranged on the skeleton or on the friction material block.Medium phosphor cast iron brake shoe: with phosphorus content is the brake shoe that 0.70～1.00% middle phosphorus cast iron is made.High phosphor cast iron brake shoe: surpass the brake shoe that 1.00% high-phosphorous iron is made with phosphorus content.Composite brake shoe: with materials such as resin, asbestos, graphite, iron powder, barium sulfate is the brake shoe that main hot pressing forms.Comprehensive speed-raising along with locomotive speed, requirement to brake shoe is more and more higher, not only requires it to have good braking characteristics, and requires the braking antithesis---wheel is not to producing abnormal abrasion and damage, adhesion between wheel, rail is not produced adverse influence, environment is not produced pollution.But this three classes brake shoe can only be used for speed per hour is lower than per hour 120 kilometers locomotive, and service life is shorter.Phosphorous brake shoe Heavy Weight, use that noise is big, dust many and poisonous.Composite brake shoe is because of containing the asbestos composition, so its heat dispersion is poor, cause intoxication accident easily.
Task of the present utility model is to provide a kind of brake shoe, and it can be used on quasi high-speed (160～180 kilometers 1 hour) railway locomotive, the vehicle, the glancing impact noiselessness, does not have flue dust, does not have public hazards.
In order to finish above-mentioned task, the solution that the utility model is taked is: a kind of brake shoe, it comprises skeleton, friction material block, bolt buckle and latch detent, welding bolt buckle in place's is located equidistant welding latch detent in the middle of on skeleton from the centre, also has steel backing, pressure sintering copper iron powder metal is as friction material block on the steel backing, and three friction material blocks and skeleton adopt rivet machine riveting to form brake shoe.
The utility model is owing to adopt copper iron powder metallurgy as friction material, compare with existing brake shoe, have that mechanical strength height, good heat resistance, resistance to abrasion are good, heat resistanceheat resistant decline function admirable, long service life, right wearing and tearing are little to taking turns, stable friction performance, glancing impact noiselessness, do not have strong chattering, do not have flue dust, do not have public hazards, characteristics such as pollution-free, and be applicable to that speed per hour is at 160～180 kilometers locomotive.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the utility model front view.
Fig. 2 is the utility model birds-eye view.
Fig. 3 is the A-A cutaway view of Fig. 2.
Fig. 4 is the B-B cutaway view of Fig. 2.
The utility model comprises skeleton (1), friction material block (4), bolt buckle (5) and latch detent (2), weld bolt buckle (5), locate equidistant welding latch detent (2) from the centre at the place in the middle of on skeleton (1), it is characterized in that steel backing (3) in addition, steel backing (3) is gone up pressure sintering copper iron powder metal as friction material block (4), and three friction material blocks (4) adopt rivet (6) machine riveting to form with skeleton (1).For steel backing (3) combines byer force with friction material block (4), on steel backing (3), have some apertures, two holes as shown in Figure 3.
Claims (2)
1, the quasi high-speed brake shoe of a kind of partial metallurgy, it comprises skeleton (1), friction material block (4), bolt buckle (5) and latch detent (2), weld bolt buckle (5), locate equidistant welding latch detent (2) from the centre at the place in the middle of on skeleton (1), it is characterized in that steel backing (3) in addition, steel backing (3) is gone up pressure sintering copper iron powder metal as friction material block (4), and three friction material blocks (4) adopt rivet (6) machine riveting to form with skeleton (1).
2, the quasi high-speed brake shoe of a kind of partial metallurgy according to claim 1 is characterized in that having some apertures on the steel backing (3).
