I-brake pad lining: isiseko esithembekileyo seziqhoboshi zemoto

nakladka_tormoznoj_kolodki_1

Isithuthi ngasinye siya kuxhotyiswa nge-braking system, ii-activators zazo ziyi-brake pads ezidibanisa ne-drum okanye i-disc.Inxalenye ephambili yeepads yi-friction linings.Funda konke malunga nala macandelo, iintlobo zazo, ukuyila kunye nokukhetha okulungileyo kwinqaku.

 

Yintoni umgca webrake pad?

I-brake pad lining (i-friction lining) yinxalenye ye-actuators ye-brakes yezithuthi, eziqinisekisa ukudalwa kwe-torque ye-braking ngenxa yemikhosi ephazamisayo.

I-friction lining iyona nxalenye ephambili ye-brake pad, idibanisa ngokuthe ngqo kunye ne-drum ye-brake okanye i-disc xa i-braking isithuthi.Ngenxa yemikhosi ekhuphisanayo evela ekudibaneni ne-drum / disc, i-lining ithatha amandla e-kinetic yesithuthi, iguqulelwe kubushushu kwaye inike ukuncipha kwesantya okanye ukuyeka ngokupheleleyo.I-Linings ine-coefficient eyongeziweyo ye-friction kunye nentsimbi etyhidiweyo kunye nentsimbi (apho iidramu ze-brake kunye neediski zenziwa khona), kwaye kwangaxeshanye zinenkcaso ephezulu yokugqoka kunye nokuthintela ukugqithisa ngokugqithiseleyo kwe-drum / disc.

Namhlanje, kukho uluhlu olubanzi lwe-brake pad linings, kwaye kukhetho oluchanekileyo lwala macandelo, kuyimfuneko ukuqonda ukuhlelwa kunye noyilo lwabo.

 

Iintlobo kunye noyilo lwe-brake pad linings

I-friction linings ye-brake pads inokwahlulwa ibe ngamaqela ngokwenjongo, ukuyila kunye nokucwangciswa, kunye nokubunjwa okuvela kuyo.

Ngokwenjongo, iipads zohlulwe zibe ziintlobo ezimbini:

• Ngeziqhoboshi zamagubu;
• Ngeziqhoboshi zediski.

I-drum brake pads yi-arcuate plate ene-radius yangaphandle ehambelana ne-radius yangaphakathi ye-drum.Xa i-braking, ii-linings ziphumla ngokubhekiselele kumphezulu wangaphakathi we-drum, ukunciphisa isantya sesithuthi.Njengomthetho, i-drum brake friction linings inommandla omkhulu wokusebenza.Isixhobo ngasinye sokuqhawuka kwevili sixhotyiswe ngeelinen ezimbini ezijongeneyo, eziqinisekisa ukusasazwa okulinganayo kwamandla.

I-Disc brake linings ziipleyiti ezisicaba zecrescent okanye ezinye iimilo ezibonelela ngowona mmandla uphezulu wonxibelelwano kunye nediski yebhuleki.Isixhobo ngasinye sokuqhawuka kwevili sisebenzisa iipadi ezimbini, phakathi apho idiski ibotshelelwe ngexesha lokuqhobosha.

Kwakhona, i-brake pad linings yahlulwe yangamaqela amabini ngokwendawo yofakelo:

• Kwiziqhoboshi zamavili - ngaphambili, ngasemva nakwindalo yonke;
• Ukulungiselela indlela yokumisa iziqhoboshi zokupaka iilori (ezinegubu kwishafti yepropeller).

Ngokwesakhiwo, i-friction linings ziipleyiti ezibunjiweyo ezivela kwi-polymer compositions kunye nokwakheka okuyinkimbinkimbi.Ukubunjwa kubandakanya amacandelo ahlukeneyo - ukwenza isakhelo, ukuzaliswa, ukutshatyalaliswa kobushushu, izibophelelo kunye nabanye.Kwangaxeshanye, zonke izinto ezenziwe ngazo iileyile zinokwahlulwa zibe ngamaqela amabini aphambili:

•Iasbestos;
• Ayina asbestos.

Isiseko se-asbestos linings, njengoko kulula ukuyiqonda, i-asbestos fibers (namhlanje i-asbestos ye-chrysotile ekhuselekileyo), esebenza njengesakhelo seplate esibamba zonke ezinye iinqununu.Iipads ezinjalo zithambile, kodwa kwangaxeshanye zine-coefficient ephezulu yokruthakruthwano, zithintela ukunxiba okugqithisileyo kwedrum / disc kwaye zinezinga lengxolo elincitshisiweyo.Kwiimveliso ezingenayo i-asbestos, i-polymer eyahlukeneyo okanye i-fibers ye-mineral idlala indima yesakhelo sokubunjwa, ezo zinto zingaphezulu zihambelana nemigangatho yokusingqongileyo, kodwa zibiza kakhulu kwaye kwezinye iimeko zineempawu ezibi kakhulu zokusebenza (ziqinile, zihlala zinomsindo, njl. .).Ke ngoko, namhlanje iilinen zokukhuhlana kwe-asbestos zisasetyenziswa ngokubanzi.

Izinto ezahlukeneyo zepolymeric zisetyenziswa njengezizalisi ekwenziweni kwezinto ezingaphezulu, iipolymers, iiresin, iirubha, njl njl. Ukongeza, iikeramics, iishavings zetsimbi (ezenziwe ngobhedu okanye ezinye iintsimbi ezithambileyo) ukwenzela ukutshabalalisa ubushushu obungcono, kunye namanye amacandelo anokubakho ekuqulunqweni. .Phantse wonke umenzi usebenzisa iiresiphi zayo (ngamanye amaxesha zizodwa), ngoko ke ukubunjwa kwe-friction linings kunokwahluka kakhulu.

I-friction linings yenziwa kusetyenziswa itekhnoloji ezimbini eziphambili:

• Ukucinezela okubandayo;
• Ukucofa okushushu.

Kwimeko yokuqala, ii-linings zenziwe ngomxube ogqityiweyo kwiimbumba ezikhethekileyo ngaphandle kokufudumeza okongeziweyo.Nangona kunjalo, abaninzi abavelisi bongezelela basebenzisa unyango olushushu lweemveliso emva kokubumba.Kwimeko yesibini, umxube ucinezelwe kwiimbumba ezifudumalayo (zombane).Njengomthetho, ngokucinezela okubandayo, i-lining, kodwa i-linings ehlala ixesha elide ifunyenwe, ngokucinezela okutshisayo, iimveliso zikumgangatho ophezulu, kodwa zibiza kakhulu.

Kungakhathaliseki ukuba yeyiphi indlela yokuvelisa kunye nokubunjwa, emva kokuvelisa, iileyili ziphuculwe kwaye zixhomekeke kwezinye iinkqubo ezongezelelweyo.I-Friction linings iyathengiswa kwiindlela ezahlukeneyo:

• Ukwaleka ngaphandle kwemingxunya kunye nezibophelelo;
• Izaleko ezinemingxuma egrunjiweyo;
• Ukwaleka ngemingxuma kunye nesethi yezibophelelo;
• Gqibezela i-brake pads - iilinen ezifakwe kwisiseko.

I-Friction linings ye-brake pads ngaphandle kwemingxuma yinxalenye yendalo yonke enokuthi ilungelelaniswe kwi-brake pads yeemoto ezahlukeneyo, ezinomlinganiselo ofanelekileyo kunye ne-radius.Ukugqithisa ngemingxuma ifanelekile kwiimodeli ezithile zemoto, kunokwenzeka ukuzifaka kwiipads kunye nelungiselelo elihlukeneyo lemingxuma kuphela emva kokugaya okongeziweyo, okanye akunakwenzeka ngokupheleleyo.Ukwaleka okupheleleyo kunye ne-fasteners kuququzelela inkqubo yofakelo kunye nokunceda ukuqinisekisa isiphumo somgangatho ophezulu.

Iipakethi ezipheleleyo ze-brake sele ziludidi olwahlukileyo lwamacandelo, zisetyenziselwa ukulungiswa kwee-disc brakes, iindlela ze-drum ezineepads ezincanyathiselwe kwi-pads, okanye iindlela zegubu ezigugile kakubi.Kwiilori, izinto ezinjalo azifane zisetyenziswe.

I-friction linings ifakwe kwi-brake pads kunye ne-rivets (eqinile kunye ne-hollow) okanye kwi-glue.Iirivets zisetyenziswa kwi-drum brakes, iglue isetyenziswa kakhulu kwi-disc brake pads.Ukusetyenziswa kweerivets kunika amandla okutshintsha iileyili njengoko ziguga.Ukuthintela umonakalo kwi-drum ye-brake okanye i-disc, ii-rivets zenziwe ngeentsimbi ezithambileyo - i-aluminium kunye ne-alloys yayo, ubhedu, ubhedu.

Izivamvo zokunxitywa koomatshini kunye ne-elektroniki zinokufakelwa kwiilinen zebrake pad zale mihla.I-sensor yomatshini iplate emzimbeni we-lining, othi, xa inxalenye igugile, iqala ukuxubha kwi-drum okanye i-disc, yenza isandi esicacileyo.I-sensor ye-elektroniki nayo ifihliwe emzimbeni we-lining, xa igugile, isiphaluka sivaliwe (ngediski okanye idrum) kunye nesalathisi esihambelanayo sikhanyisa kwideshibhodi.

 

Ukukhetha okuchanekileyo, ukutshintshwa kunye nokusebenza kwee-linings ze-brake pad

I-Friction linings iphantsi kokugqoka ngexesha lokusebenza, ubukhulu bayo buyancipha ngokuthe ngcembe, okukhokelela ekunciphiseni ukuthembeka kweebhuleki.Njengomthetho, i-lining enye ikhonza i-15-30 yeekhilomitha eziliwaka, emva koko kufuneka itshintshwe.Kwiimeko ezinzima zokusebenza (ukunyuka kothuli, ukunyakaza kwamanzi kunye nokungcola, xa usebenza phantsi kwemithwalo ephezulu), ukutshintshwa kwee-linings kufuneka kwenziwe rhoqo.Iilinen kufuneka zitshintshwe xa zigqitywe kumlinganiselo omncinci ovumelekileyo - ngokuqhelekileyo ubuncinane ubuncinane be-2-3 mm.

Ukutshintshwa, kuyimfuneko ukusebenzisa i-friction linings enemilinganiselo efanelekileyo kwimoto ethile - ububanzi, ubude kunye nobukhulu (zonke iiparitha eziyimfuneko zidla ngokuboniswa kwii-linings).Kule meko kuphela, i-lining iya kucinezelwa ngokupheleleyo kwi-drum okanye i-disc kunye ne-braking force eyaneleyo iya kwenziwa.Ukufakela i-pad kwibhloko, ungasebenzisa kuphela i-rivets ezenziwe ngeentsimbi ezithambileyo, kungcono ukunika ukhetho kwiifasteners kwikiti.Iirivethi kufuneka zingcwatywe kumzimba weentambo zokuthintela ukukhuhla kwigubu, kungenjalo amalungu aya kuba phantsi kokuguga nokukrazuka okukhulu kwaye anokusilela.

Kuyimfuneko ukuba utshintshe i-linings kwii-brake pads kwiisethi ezipheleleyo, okanye, kwiimeko ezigqithisileyo, zombini kwivili elifanayo - le ndlela yodwa yokuqinisekisa ukusebenza okuqhelekileyo kweendlela zokuqhawula.Kuyimfuneko ukuba kuqhutywe ukutshintshwa ngokupheleleyo ngokuhambelana nemiyalelo yokulungiswa nokugcinwa kwemoto ethile, ngaphandle koko kukho amathuba aphezulu okuwohloka kwamabhuleki.

Xa uqhuba imoto, kufuneka ugweme ukugqithiswa kwe-linings, kunye nokumanzisa kunye nokungcoliswa - konke oku kunciphisa ubutyebi babo kwaye kwandisa amathuba okuphuka.Xa uqhuba emanzini, i-linings kufuneka yomiswe (ukukhawuleza amaxesha amaninzi kwaye ucinezele i-pedal ye-brake), kunye nokwehla okude, kuyacetyiswa ukuba ubhenele kwi-injini ye-injini, njl. iya kusebenza ngokuthembekileyo nangokukhuselekileyo.
