The elastic support piece comprises a spherical support surface part, a central guide hole part and a fixing support detent part, wherein the spherical support surface part supports a support spherical surface of friction block bodies of a brake pad, the central guide hole part leads guide connection shafts of the friction block bodies of the brake pad into positioning holes of the friction block bodies of a brake pad back panel, and the fixing support detent part is installed in support facing holes in the front surface of the brake pad back panel. The elastic support piece enables the friction bodies of the brake pad to be freely adjusted in a spherical support surface of the elastic support piece, so that the floating function of the friction bodies is achieved.
Description
Technical field
The utility model relates to a kind of elastic support sheet, particularly a kind ofly produces float function and elastic support sheet that can balancing brake pressure be used to making brake lining brake pad body can freely adjust the working position.
Background technique
In the train disk braking system, brake pad is one of critical component, and direct and brake disc friction absorbs kinetic energy, and train braking is stopped.Therefore to guarantee the maximum effectively friction area of brake pad and brake disc.
Existing brake lining mounting type mostly is riveted joint, dovetail groove grafting etc., and this class mounting type is unfavorable for the adjustment of brake lining self-position in braking process, in order to reduce the brake lining running-in time, to obtain the maximum effectively friction area of brake lining and brake disc.Allowing brake lining friction block to have in the mounting type of freely adjusting, can use the spherical of elastic support sheet partly to support the support sphere of brake lining friction block, making the block acquisition that rubs freely to adjust the float function of position.Simultaneously, elastic support sheet can also reduce vibrations and the noise that braking produces by balancing brake pressure.
Summary of the invention
The utility model is a kind of elastic support sheet.When its purpose was train braking, the fricting working surface of friction block and brake disc braking working surface obtained maximum contact friction area; While is the maximum retardation pressure of stepless action on the brake lining backboard also.Safe and reliable with the braking of guaranteeing bullet train.Particularly brake pad is safe and reliable.
The utility model elastic support sheet comprises spherical part, centre pilot bore portion and fixed support ratchet part.
The spherical of described elastic support sheet is (11) partly, support the support sphere of brake lining friction block, make the friction block obtain freely to adjust the float function of position.
The centre pilot bore portion (12) of described elastic support sheet enters the rub guiding coupling shaft guiding of block of brake lining in the brake lining backboard friction block positioning hole.
The fixed support ratchet part (13) of described elastic support sheet is installed in the flat hole of support ream in brake lining backboard front.
The utility model elastic support sheet, fixed support ratchet partial fixing in the flat hole of location ream of friction block, its fixed support friction block and by the spherical part so that the brake pad body can freely be adjusted working surface, thereby obtain the floating structure mode.The centre pilot bore portion is that the rub guiding coupling shaft guiding of block of brake lining is entered in the brake lining backboard friction block positioning hole, in the flat hole of spring clamp ream of brake lining backboard, and the spring clamp that is installed, fixed friction block.Therefore, the elastic support sheet of model utility has the brake lining of finishing friction block floating structure, and makes the brake pad body can freely adjust the function of best operational position.

Embodiment
With reference to description of drawings the utility model.
The utility model elastic support sheet comprises spherical part (11), centre pilot bore portion (12) and fixed support ratchet part (13).
Its elastic deformation amount of the utility model elastic support sheet is depended on shaping operation and the heat treatment process of high temperature resistant rustproof spring steel material.Provided single friction block floating structure sectional drawing by Fig. 3, there are a plurality of friction blocks (2) to connect positioning hole (33) on the brake pad backboard (3), the positive of backboard has the flat holes of a plurality of support plate reams (31), and there are the flat holes of a plurality of spring clamp reams (32) at the back side of backboard.The fixed support ratchet (13) of elastic support sheet (1) is positioned in the flat hole of support plate ream in backboard front (31).The guiding coupling shaft (22) of block (2) of will rubbing passes the centre pilot hole (12) of elastic support sheet, the friction block that passes again backboard connects positioning hole (33), is supported the spherical (24) of friction block root by the spherical (11) of elastic support sheet.Afterwards, in the flat hole of spring clamp ream (32) of backboard, spring clamp (4) supporting leg (41) and circular collar (42) are clamped in the spring card slot (23) on the friction block coupling shaft.
Elastic support sheet of the present utility model (1), when train braking, brake disc rotates with the train motion, and brake pad is subject to rubbing in the brake disc close contact behind the retardation pressure, so require brake pad with respect to brake disc maximum effectively area of contact to be arranged.Rubbed shown in the block floating structure sectional drawing by Fig. 3, the friction block can freely be adjusted in the horizontal direction, until per 3 friction block engaging locks tight till; The friction block can also be done free adjustment in any Vertical direction, so that the fricting working surface of friction block farthest contacts with brake disc, dynamic free adjustment process so namely occurs in the moment of braking beginning, also among whole braking process.Elastic support sheet can make braking process obtain maximum effectively contact friction area, can also omit or shorten the period of adjustment of new brake lining.
Because the existence of floating structure Elastic support plate, balance the retardation pressure on all friction blocks, make braking more steady.Simultaneously elastic support sheet also damping the instantaneous variation of retardation pressure, thereby the vibration when having reduced braking work and the noise that produces when having reduced braking work.Or because the existence of elastic support sheet makes between friction block and the backboard and produced the gap, the existence in this gap has greatly helped the rapid heat radiation of friction block, thereby has effectively avoided brake disc owing to overheated turning blue and decrepitation of occuring.
