Abstract
The invention provides a novel high-speed brake lining. A connecting board is added on a steel back, a forked tail board is disposed on the connecting board, and the connecting board and the steel back are in a riveted joint. Welding deformation of the steel back and the forked tail board is eliminated, the strength of the steel back is improved so that the steel back is prevented from being deformed or chattered under the action of a pushing force of braking, an elastic pad is installed between the steel back and a framework of a braking block, and the braking block can be effectively and closely attached to a brake disc to perform friction braking. By means of the structure, the braking block can be closely attached to the brake disc on the same plane to perform braking, eccentric wear is avoided, and problems that edges and angles of the braking block are prone to be worn away, the braking efficiency is low, and the braking distance is excessively long due to eccentric wear are solved.
Description
Technical field
The present invention relates to the high-speed train braking device, relate in particular to the novel high speed brake lining.
Background technique
The high speed brake lining is key element in the high-speed train braking system, mainly formed by a plurality of brake block, steel backing and coattail board etc., wherein the effect of coattail board is that the high speed brake lining is fixed on the braking device of bullet train, in the brake process, a plurality of brake block of high speed brake lining at grade with the brake disc friction of bullet train, train stopped stops.Yet, widely used high speed brake lining in the prior art, Placement between its coattail board and the steel backing adopts the point type welding, and the position that namely contacts with steel backing in W shape coattail board bottom processes several through holes, in through hole spot welding coattail board and steel backing is linked together.Produce localized hyperthermia in welding process, very easily cause the steel backing distortion, the distortion of steel backing namely causes a brake block not at grade, although can be eliminated by follow-up machine add mode, the coattail board distortion that welding causes can't be eliminated.After this high speed brake lining was installed on the braking device of bullet train, so that brake block can not well fully contact with brake disc, braking quality was unstable, efficient is low, and under high speed, high brake energy, high pressure, this phenomenon is more serious, and potential safety hazard is very big.Simultaneously, weld seam can exist pore, crackle, rosin joint phenomenon unavoidably during welding, has equally potential safety hazard.
Summary of the invention
For the problems referred to above, the invention provides the novel high speed brake lining, behind steel backing, increase connecting plate, coattail board is arranged on the connecting plate, connecting plate and steel backing riveted joint.Both eliminated welding deformation, and strengthened again the intensity of steel backing, brake block can be out of shape or tremble under the effect of brake thrust, thereby brake block can more effectively fit tightly and friction catch with brake disc.
Concrete technological scheme of the present invention is:
The novel high speed brake lining mainly comprises steel backing, brake block and coattail board, and the front riveted joint of steel backing has brake block, and the back side riveted joint of steel backing has connecting plate, and connecting plate is provided with coattail board; The material prescription weight percentage that described brake block adopts is: copper powder 58, iron powder 4, glass putty 4, chromium powder 2, titanium valve 2, nickel powder 4, bismuth meal 2, graphite 9, boron nitride 1, aluminium sesquioxide 3, silica 6, zircon 5.
For preventing that the miscellaneous part on connecting plate and the high-speed train braking device from interfering, the boundary dimension of described connecting plate 4 is not more than the size of steel backing 1.
For further strengthening the join strength of coattail board and high speed brake lining body, described coattail board is the U-shaped plate of perk on the connecting plate body.
For further guarantee each brake block at grade with the brake disc friction, make brake block possess the ability of self adaption brake disk surface, between brake block and steel backing, be provided with resilient pad.
For guaranteeing riveting intensity, the rivet outer wall entire body of riveting each parts is socketed with lining.
For further strengthening the join strength between steel backing and the connecting plate, riveted joint has the reinforcement bolt between steel backing and the connecting plate.
Novel high speed brake lining provided by the invention increases connecting plate behind steel backing, coattail board is arranged on the connecting plate, connecting plate and steel backing riveted joint.Both eliminated the welding deformation of steel backing and coattail board, strengthened again the intensity of steel backing, steel backing can be out of shape or tremble under the effect of brake thrust, and between the skeleton of steel backing and brake block, resilient pad has been installed, thereby brake block can more effectively fit tightly and friction catch with brake disc.Because said structure, under the promotion of brake pressure, brake block can be adjacent at grade brake disc and brake, avoided eccentric wear and by the brake block that eccentric wear causes fall easily the limit arrisdefect, braking efficiency is low and the variety of issue such as poor stop.

Embodiment
The present invention is described further below in conjunction with accompanying drawing, such as Fig. 1 ~ shown in Figure 4, the novel high speed brake lining mainly comprises steel backing 1, brake block 2 and coattail board 7, and the front riveted joint of steel backing 1 has brake block 2, the back side riveted joint of steel backing 1 has connecting plate 4, and connecting plate 4 is provided with coattail board 7; The material prescription weight percentage that described brake block 2 adopts is: copper powder 58, iron powder 4, glass putty 4, chromium powder 2, titanium valve 2, nickel powder 4, bismuth meal 2, graphite 9, boron nitride 1, aluminium sesquioxide 3, silica 6, zircon 5, the above-mentioned material prescription with prior art cold pressing, sintering makes brake block 2 at skeleton.Dotted line among Fig. 1 is the outer margin contour of coattail board 7, and the quantity of brake block 2 depends on the area of steel backing 1.
For preventing that the miscellaneous part on connecting plate and the high-speed train braking device from interfering, the boundary dimension of described connecting plate 4 is less than or equal to the size of steel backing 1, and can not be greater than the boundary dimension of steel backing 1.
As shown in Figure 3 and Figure 4, for further strengthening the join strength of coattail board 7 and high speed brake lining body, described coattail board 7 is the U-shaped plate of perk on connecting plate 4 bodies.This U-shaped plate is the flange that directly is stamped to form on connecting plate 4.Dotted line among Fig. 3 is the outer margin contour of coattail board 7.
As shown in Figure 1 and Figure 4, for guaranteeing that further each brake block 2 rubs with brake disc at grade, make brake block 2 possess the ability of self adaption brake disk surface, be provided with resilient pad 3 between brake block 2 and steel backing 1, this resilient pad 3 can use the high strength shell fragment commonly used such as dish-shaped shell fragment, waveform splinter.
For guaranteeing riveting intensity, the rivet outer wall entire body of riveting each parts is socketed with lining 6.The shearing force of skeleton, resilient pad 3, steel backing 1 and connecting plate 4 that the effect of lining 6 is to avoid rivet directly to bear brake block 2, the rivet 5 among Fig. 2 can adopt same size also can take different specifications with rivet 8.
For further strengthening the join strength between steel backing 1 and the connecting plate 4, riveted joint has the bolt 9 of reinforcement between the two, and the effect of this reinforcement bolt also is to bring great convenience for the assembling of whole product.
