Brake pad line ke eng?
Brake pad lining (friction lining) ke karolo ea li-actuator tsa li-brake tsa likoloi, tse netefatsang ho thehoa ha torque ea braking ka lebaka la matla a khohlano.
The friction linening ke karolo e ka sehloohong ea brake pad, e amana ka ho toba le moropa oa brake kapa disc ha o pshatla koloi.Ka lebaka la matla a khohlano a bakoang ke ho kopana le moropa / disc, lesela le monya matla a kinetic a koloi, ho e fetola mocheso le ho fana ka phokotso ea lebelo kapa ho emisa ho felletseng.Li-linings li na le coefficient e eketsehileng ea ho ferekanngoa le tšepe e entsoeng ka tšepe le tšepe (tseo ho tsona ho etsoang meropa le li-discs), 'me ka nako e ts'oanang li na le khanyetso e phahameng ea ho apara le ho thibela ho apara ka mokhoa o feteletseng oa drum / disc.
Kajeno, ho na le mefuta e mengata e fapaneng ea li-brake pad linings, 'me bakeng sa khetho e nepahetseng ea likarolo tsena, hoa hlokahala ho utloisisa likarolo le moralo oa tsona.
Mefuta le moralo oa li-brake pad linings
Li-friction linings tsa brake pads li ka aroloa ka lihlopha ho latela morero, moralo le tlhophiso, hammoho le sebopeho seo li entsoeng ho sona.
Ho ea ka morero, li-pads li arotsoe ka mefuta e 'meli:
• Bakeng sa mariki a meropa;
• Bakeng sa mariki a disc.
Li-drum brake pads ke poleiti ea arcuate e nang le radius e ka ntle e tsamaellanang le radius e ka hare ea moropa.Ha braking, li-linings li phomola khahlanong le bokaholimo ba moropa, ho fokotsa lebelo la koloi.E le molao, li-drum brake friction linings li na le sebaka se seholo sa ho sebetsa.Mochini o mong le o mong oa brake oa mabili o na le li-linings tse peli tse shebaneng, tse netefatsang ho ajoa ha matla.
Li-brake linings ke lipoleiti tse bataletseng tsa crescent kapa libopeho tse ling tse fanang ka sebaka se phahameng sa ho kopana le "brake disc".Mochini o mong le o mong oa brake oa lebili o sebelisa li-pads tse peli, tseo disc e hatelloang lipakeng tsa braking.
Hape, li-brake pad linings li arotsoe ka lihlopha tse peli ho ea ka sebaka sa ho kenya:
• Bakeng sa mariki a mabili - ka pele, ka morao le ka bokahohle;
• Bakeng sa mochine oa mariki oa ho paka oa literaka (tse nang le moropa holim'a shaft ea propeller).
Ka mokhoa o hlophisitsoeng, li-fraction linings ke lipoleiti tse bōpiloeng ka lihlopha tsa polymer tse nang le motsoako o rarahaneng.Sebopeho se kenyelletsa likarolo tse fapaneng - ho etsa foreimi, ho tlatsa, ho senya mocheso, li-binders le tse ling.Ka nako e ts'oanang, lisebelisoa tsohle tseo masela a entsoeng ka tsona a ka aroloa ka lihlopha tse peli tse kholo:
•Asbestos;
• E se nang asbestos.
Motheo oa li-asbestos linings ke, kaha ho bonolo ho o utloisisa, likhoele tsa asbestos (kajeno ke asbestos e batlang e sireletsehile ea chrysotile), e sebetsang e le foreimi ea poleiti e tšoereng likarolo tse ling kaofela.Li-pads tse joalo li bonolo, empa ka nako e ts'oanang li na le coefficient e phahameng ea likhohlano, li thibela ho roala ho feteletseng ha moropa / disc le ho fokotsa molumo oa lerata.Ka lihlahisoa tse se nang asbestos, likhoele tse fapaneng tsa polymer kapa liminerale li bapala karolo ea sebopeho sa sebopeho, li-overlays tse joalo li lumellana le maemo a tikoloho, empa li theko e boima haholo 'me maemong a mang li na le litšobotsi tse mpe tsa ts'ebetso (li thata, hangata li lerata, jj. .).Ka hona, kajeno masela a khohlano a asbestos a ntse a sebelisoa haholo.
Lisebelisoa tse fapaneng tsa polymeric li sebelisoa e le li-filler ha ho etsoa li-overlays, li-polymers, resin, rubbers, joalo-joalo Ho phaella moo, li-ceramics, li-shavings tsa tšepe (tse entsoeng ka koporo kapa litšepe tse ling tse bonolo) bakeng sa ho senya mocheso hantle, le likarolo tse ling li ka ba teng ka har'a sebopeho. .Hoo e batlang e le moetsi e mong le e mong o sebelisa litlolo tsa hae (ka linako tse ling tse ikhethang), kahoo sebopeho sa li-friction linings se ka fapana haholo.
Li-friction linings li etsoa ho sebelisoa mahlale a mabeli a mantlha:
• Ho hatella ho batang;
• Ho tobetsa ho chesang.
Boemong ba pele, li-linings li thehoa ho tloha motsoako o phethiloeng ka hlobo e khethehileng ntle le ho futhumatsa ho eketsehileng.Leha ho le joalo, bahlahisi ba bangata ba sebelisa kalafo ea mocheso ea lihlahisoa ka mor'a ho bopa.Tabeng ea bobeli, motsoako o hatelloa ka liforomo tse futhumetseng (motlakase).E le molao, ka ho hatella ho batang, ho fumanoa li-linings tse theko e tlaase, empa tse sa tšoarellang, ka ho hatella ho chesang, lihlahisoa ke tsa boleng bo phahameng, empa hape li theko e boima haholo.
Ho sa tsotellehe mokhoa oa ho hlahisa le ho hlophisoa, ka mor'a ho etsa lihlahisoa, li-linings li hloekisoa 'me li tlas'a ts'ebetso e meng e eketsehileng.Li-friction linings li rekisoa ka litlhophiso tse fapaneng:
• Li-overlays ntle le masoba le li-fasteners;
• Li-overlays tse nang le masoba a phuntsoeng;
• Li-overlays tse nang le masoba le sete ea li-fasteners;
• Li-brake pads tse felletseng - li-linings tse kentsoeng motheong.
Li-friction linings tsa li-brake pads tse se nang masoba ke likarolo tsa bokahohleng tse ka fetoloang ho li-brake pads tsa likoloi tse fapaneng, tse nang le litekanyo tse loketseng le radius.Li-overlays tse nang le masoba li loketse mefuta e itseng ea likoloi, ho ka khoneha ho li kenya holim'a liphahlo ka tokisetso e fapaneng ea likoti feela ka mor'a ho cheka ho eketsehileng, kapa ho ke ke ha khoneha ka ho feletseng.Li-overlay tse felletseng ka li-fasteners li thusa ho kenya tšebetsong le ho thusa ho netefatsa sephetho sa boleng bo holimo.
Li-brake pads tse felletseng e se e ntse e le mofuta o arohaneng oa likarolo tse ling, li sebelisoa ho lokisong ha li-disk brakes, meropa e nang le li-pads tse khomaretsoeng ho li-pads, kapa mekhoa ea meropa e senyehileng hampe.Literakeng, likarolo tse joalo ha li sebelisoe ka seoelo.
Li-friction linings li kenngoa holim'a li-brake pads tse nang le li-rivets (tse tiileng le tse se nang letho) kapa holim'a sekhomaretsi.Li-rivets li sebelisoa ka har'a mariki a meropa, sekhomaretsi se sebelisoa hangata ho li-brake pads.Tšebeliso ea li-rivets e fana ka bokhoni ba ho fetola li-linings ha li ntse li senyeha.Ho thibela tšenyo ea moropa oa brake kapa disc, li-rivets li entsoe ka tšepe e bonolo - aluminium le li-alloys tsa eona, koporo, koporo.
Li-sensor tsa mochini le tsa elektronike li ka kenngoa holim'a li-brake pad linings tsa sejoale-joale.Sensor ea mechine ke poleiti 'meleng oa lesela, eo, ha karolo e senyeha, e qala ho senya khahlanong le drum kapa disc, ho etsa molumo oa tšobotsi.Sensor ea elektronike e boetse e patiloe 'meleng oa lesela, ha e apere, potoloho e koetsoe (ka disk kapa drum)' me pontšo e lumellanang e khantša dashboard.
Khetho e nepahetseng, phetoho le ts'ebetso ea li-brake pad linings
Li-friction linings li ka roaloa nakong ea ts'ebetso, botenya ba tsona bo fokotseha butle-butle, e leng se lebisang ho fokotseha ha ho tšepahala ha mariki.E le molao, lesela le le leng le sebetsa lik'hilomithara tse likete tse 15-30, ka mor'a moo le tlameha ho nkeloa sebaka.Maemong a thata a ts'ebetso (ho eketseha ha lerōle, ho tsamaea holim'a metsi le litšila, ha u sebetsa tlas'a meroalo e phahameng), ho nkeloa sebaka ha linings ho lokela ho etsoa hangata.Li-linings li lokela ho fetoloa ha li apesoa ho isa botenya bo lumelletsoeng - hangata bonyane 2-3 mm.
Bakeng sa ho nkela sebaka, hoa hlokahala ho sebelisa li-friction linings tse nang le litekanyo tse loketseng koloi e itseng - bophara, bolelele le botenya (mekhahlelo eohle e hlokahalang hangata e bontšoa ka linings).Ke feela tabeng ena, lesela le tla hatelloa ka ho feletseng khahlanong le drum kapa disc le matla a lekaneng a ho tiisa a tla thehoa.Bakeng sa ho kenya lesela holim'a block, o ka sebelisa li-rivets feela tse entsoeng ka tšepe e bonolo, ho molemo ho fana ka khetho ho li-fasteners ka har'a kit.Li-rivets li lokela ho patoa 'meleng oa masela ho thibela hore li se ke tsa hohla khahlanong le moropa, ho seng joalo likarolo li tla senyeha ho matla le ho taboha' me li ka 'na tsa hlōleha.
Hoa hlokahala ho fetola li-linings holim'a li-brake pads ka lihlopha tse feletseng, kapa, maemong a feteletseng, ka bobeli ka lebili le le leng - ena ke eona feela tsela ea ho netefatsa ts'ebetso e tloaelehileng ea mekhoa ea ho senya.Hoa hlokahala ho etsa phetoho ka botlalo ho latela litaelo tsa ho lokisa le ho lokisa koloi e itseng, ho seng joalo ho na le monyetla o moholo oa ho senyeha ha mariki.
Ha u sebelisa koloi, u lokela ho qoba ho chesa ha li-linings, hammoho le ho kolobisa le ho silafala ha tsona - sena sohle se fokotsa lisebelisoa tsa bona mme se eketsa menyetla ea ho senyeha.Ha u khanna ka metsing, li-linings li hloka ho omisoa (potlakisa makhetlo a 'maloa' me u hatelle pedal ea brake), e nang le litheolelo tse telele, ho kgothaletswa hore o sebelise braking ea enjene, joalo-joalo. e tla sebetsa ka botshepehi le ka polokeho.
