Description
Technical field
This utility model relates to a kind of brake pad, particularly relates to a kind of railroad train brake pad.
Background technology
Research to friction cause, has simple anti-skidc ontrols ystem, and the anti-skidc ontrols ystem of correction, surface exist the reason of polluted membrane
Multiple hypotheses and the models such as opinion, ditch dug with a plow impact, energy theory.For brakes, the element set of mechanism mainly has braking
Dish, brake pad, pollutant (abrasive dust, sand and dust etc.) etc..Input is motion and kinetic energy (merit)；Output is frictional heat, noise, shakes
Dynamic, motion etc.；The major function of system is to reduce movement velocity or stop motion.
The Frotteurism of friction pair is segmented into following several state or following several stages:
1. coefficient of friction is by plow component influences.Owing to surface contamination or friction surface break-in polish, produce the newest
Micro-bulge, microcosmic surface unevenness reduces, and the plastic deformation of micro-bulge is little, adheres the slightest.This stage coefficient of friction
Unrelated with combination of materials, but relevant with the apparent condition of friction pair.
2. surface of friction pair adhesion rises, and frictional force increases；If micro-bulge deformation, fracture, the abrasive dust of generation rests on
Slidingsurface, coefficient of friction can rapid increase.
3. the abrasive dust between slidingsurface increases, and coefficient of friction increases, and frictional force rises；Fricative fresh clean surface
Adhesion increase, coefficient of friction continue increase, frictional force continue rise.
4. the abrasive dust staying interface is not further added by, and the contribution to friction of adhering is constant, owing to the fracture of micro-bulge occurs new
Coarse, micro-bulge deforms, and produces new probability coarse, that form new micro-bulge and reduces, and under this situation, coefficient of friction is big
Body is constant；
5. state 4) after, formation pit, hole if micro-bulge comes off, abrasive dust is trapped in again frictional interface or is embedded in
On friction surface, plow and cutting friction surface, coefficient of friction increases, and interface friction heat accumulation, friction Temperature Rise causes the tightest
The abrasive wear of weight；Abrasive particle increases, reassociates, plow and abrasive wear effect aggravation, and interface friction state deteriorating, temperature continues
Rising, friction system enters a vicious cycle, and friction pair lost efficacy rapidly.
6. state 4) after, the micro-bulge on crust gradually grinds off, and abrasive dust is not trapped on hard rubbing surface；Pressure release surface
By the declines of plow, sticking friction is main, the declines of plow；Crust becomes minute surface on a large scale, and pressure release surface is also same
Sample becomes minute surface, and coefficient of friction maintains reduced levels.
Only there is certain several state in some friction pairs: the friction pair such as having is from the most 4., and this is a stable mill
The state damaged；Have the most 5., this be one experience of short duration steady statue, be put into the shape of Fast Wearing
State；Have the most 6., here it is one quickly enters stable abrasion, running life is by the longest state etc..From friction shape
State and being converted is seen, whether the Frotteurism of friction pair is affected by the gathering at interface of friction pair interface temperature, abrasive particle, abrasive dust
The biggest.
Mechanical braking system, is all by frictional damping, and friction, along with abrasion, the most all can produce abrasive dust.Train is transported
Row also can take up dirt husky, engaging friction interface；The ice and snow of cold snap, sweeps along dirt husky, covers at brake disc and damper brake
On sheet, after heat is melted, these sand and dust may left behind, and is bonded at frictional interface or their some ditches of brake unit
Among groove.Humidity makes sand and dust have an opportunity to stick on friction parts and be brought into frictional interface, participates in abrasive wear, and manufactures more

Rivet between element, is fixedly connected on brake pad on chassis by rivet, thus cause brake pad on brake pad with
The problem can not fitted completely between brake disc, there is crackle, falls block, defect, damper brake in the high stress point of brake pad
The service life of sheet reduces.
It addition, train mechanical braking system is under winter's snow and ice weather condition, frequently occurs inordinate wear and lost efficacy in advance
Situation；Concrete condition is as follows: polishing scratch that brake disc surface rubs out the deepest, ditch dug with a plow, the gash depth even ground reaches 6-
7mm, the most brake disc of train and brake pad need to change.This situation serious threat arrived train operation safety with
Reliability；It addition, substantial amounts of replacing and maintenance, considerably increase the operation maintenance cost of train operation department, even can't bear
Heavy burden.Train is runed under normal weather conditions, and the inordinate wear and the early stage that the most also there will be brake pad lost efficacy；Simply exist
Under the weather conditions of winter's snow and ice, frequency and the degree of wear of the inordinate wear of mechanical braking system are more apparent, the most more serious.
Causing inordinate wear and the main cause lost efficacy in advance is that extraneous hard particles foreign body is clipped in brake disc and damper brake
Brake disc is caused to scratch between sheet rubbing surface.Train in running, brake lining and brake disc phase mutual friction, in roadbed sand grains or
External hard foreign body is blended in ice and snow, and be wrapped on brake lining and brake clamp be difficult to discharge.Hard foreign body grinding brake disc,
Produce metal filings or cut tinsel.If running into the weather that snows, the metal filings of generation can not be timely by ice and snow parcel
Come off or metal filings is stuck in brake lining slit together with other foreign material, continue said process, regrinding brake disc will be added, mill
Cut thing in brake lining Surface Creation damascene.
Visible, winter's snow and ice weather is the abnormal inducement scratching phenomenon of train brake disk, and extraneous hard particles foreign body folder
Can not come off between brake disc and brake lining rubbing surface and cause brake disc cut, consequent metal cutting thing continues grinding
Brake disc surface also causes metal at brake lining surface sediment, in turn results in the exception to brake disc friction surface and scratches.
