The invention provides a floating rotatable high-speed brake lining which comprises a brake block, a framework and a steel backing. The brake block is sintered on the framework which is welded at the upper end of a T-type connecting rod, an I-type through hole is arranged on the steel backing, a cylinder spring and a U-type supporting seat are mounted inside the upper end of the I-type through hole, the cylinder spring is pressed inside the upper end of the I-type through hole by the U-type supporting seat, the connecting rod penetrates through the U-type supporting seat and the I-type through hold of the steel backing, and the lower end of the T-type connecting rod is clamped inside the lower end of the I-type through hole of the steel backing by an elastic retainer ring. The brake block is capable of automatically clinging to a brake disc for braking under pushing of brake pressure, so that various problems of eccentric wear and proneness to edge and corner chipping of the brake block, low braking efficiency, over-long braking distance and the like caused by eccentric wear are avoided.
Description
Technical field
The present invention relates to the high-speed train braking device, relating in particular to floats can turn the high speed brake lining.
Background technique
Brake block is important parts in bullet train or the rail motor set brake unit, thereby plays the key effect that friction brake disk is realized braking.Owing to the initial velocity height of high-speed train braking, from great, brake block need to be converted to heat energy with huge friction kinetic energy in braking process, the brake block heat load of brake block is huge, causes easily the brake block Yin Wendu of the brake block heat that sharply raises can not in time shed and be full of cracks occurs and fall limit arrisdefect phenomenon.Simultaneously, because brake block of the prior art, can not be fully in its brake block ubiquity braking process and the brake disk surface problem of fully fitting and rubbing, namely produce eccentric wear, brake block falls limit arrisdefect, low, the poor stop of braking efficiency easily.Eccentric wear also can cause the brake block loss too fast, and the skeleton of brake block or steel backing scratch brake disc.The problems referred to above of new brake block are more obvious, need the long break-in cycle could realize relative identical with brake disc, but the eccentric wear problem can't be eliminated always.
Summary of the invention
For the problems referred to above, the invention provides floats can turn the high speed brake lining, and its each brake block is when rub with brake disc, and the Self-adjustment that brake block can be gone up under the effect of brake thrust is in any direction realized and the fitting tightly and rubbing of brake disc.
Concrete technological scheme of the present invention is:
Float and to turn the high speed brake lining, comprise brake block, skeleton and steel backing, the brake block sintering is on skeleton, frame welding is in the upper end of T-shaped connecting rod, steel backing is provided with I type through hole, and cylindrical spring and U-shaped supporting base are installed in the inside of I type through hole upper end, and cylindrical spring is pressed in the inside of I type through hole upper end by U-shaped supporting base, the I type through hole of U-shaped supporting base and steel backing is passed in the lower end of T-shaped connecting rod, and elastic collar is stuck in the lower end of T-shaped connecting rod the inside of steel backing I type through hole lower end; The material prescription weight percentage that described brake block (1) adopts is: copper powder 55, iron powder 6, glass putty 5, 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 further guaranteeing the smooth of brake block angular adjustment, T-shaped connecting rod and U-shaped supporting base outer surface sphere cooperate.
Be the distance of convenient adjusting brake block with respect to brake disc, the elastic force of elastic collar is greater than the elastic force of cylindrical spring.
For further facilitating the angle of regulating brake block and brake block with respect to the distance of brake disc, I type through hole upper end is used for holding the part of U-shaped supporting base on the steel backing, and its degree of depth is equal to the thickness of U-shaped supporting base.
For making things convenient for the location of cylindrical spring, the position of U-shaped supporting base Compress Spring is provided with spring groove, and the bottom of the I type through hole upper end of steel backing is provided with the cylindrical spring locating slot.
For preventing that skeleton from driving the brake block rotation, skeleton is provided with stop pin, and an end of stop pin is fixed on the skeleton, and the other end is suspended from the spacing hole on the steel backing.
For making in the stable I type that the is fixed on through hole of T-shaped connecting rod, elastic collar produces distortion along with moving forward and backward of T-shaped connecting rod, be that diameter increases or dwindles, for making things convenient for elastic collar in the distortion of inside, steel backing I type through hole lower end, the inside diameter of described steel backing I type through hole lower end is greater than the diameter of elastic collar.
Provided by the invention float can turn the high speed brake lining, increased cylindrical spring and U-shaped supporting base between brake block and steel backing, and the sphere that is welded in employing convex-concave between the outer surface of T-shaped connecting rod and U-shaped supporting base on the skeleton cooperates.Because said structure, under the promotion of brake pressure, brake block can be braked by the automatic paste tightening brake disc, 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.
