Li-brake pads li senya mohopolo oa setso oa li-brake pads, li-brake pads li entsoe ka likhoele tsa ceramic, lintho tse se nang tšepe tse se nang tšepe, likhomaretsi le tšepe e nyane.
Li-brake pads ke mofuta oa li-brake pads, bareki ba bangata ba tla fosahetse ka ceramic qalong, ha e le hantle, li-brake pads tsa ceramic li tsoa motheong oa li-ceramics tsa tšepe ho fapana le li-ceramics tse seng tsa tšepe, li-brake pads ka lebaka la ho ts'oaroa ka lebelo le phahameng, mocheso o phahameng. ka holim'a likhohlano, ho ea ka tekanyo, e ka fihla likhato tse 800 ~ 900, 'me tse ling le ho feta. Ka mocheso ona o phahameng, bokaholimo ba brake pad bo tla ba le karabelo e tšoanang ea cermet sintering, e le hore brake pad e be le botsitso bo botle mochesong ona. Li-brake pads tsa setso li ke ke tsa hlahisa karabelo ea sintering ka mocheso ona, ka lebaka la ho phahama ho hoholo ha mocheso oa holim'a metsi ho tla qhibilihisa thepa e ka holimo esita le ho hlahisa mosamo oa moea, o tla baka phokotso e matla ea ts'ebetso ea brake kapa tahlehelo ea brake kamora ho ts'oaroa ho sa khaotseng.
Likarolo tsa Ceramic Brake Pad:
Lerōle le fokolang holim'a mabili; Bophelo bo bolelele ba lipoleiti le lipara; Ha ho lerata / ha ho thothomelo / ha ho tšenyo ea disc. Tshebetso e khethehileng ke e latelang:
(1) Phapang e kholo ka ho fetisisa pakeng tsa li-brake pads le li-brake pads tsa setso ke hore ha ho na tšepe. Tšepe ka har'a li-brake pads tse tloaelehileng ke lisebelisoa tse ka sehloohong tsa ho ferekana, matla a braking a maholo, empa seaparo se seholo, 'me lerata le bonolo ho hlaha. Ka mor'a ho kenya li-brake pads tsa ceramic, ka ho khanna ka mokhoa o tloaelehileng, ho ke ke ha e-ba le lerata le sa tloaelehang (ke hore, molumo oa ho phunya). Hobane li-brake pads tsa ceramic ha li na likarolo tsa tšepe, lerata la tšepe la likhohlano pakeng tsa li-brake pads tsa setso le likarolo tse peli (ke hore, li-brake pads le brake disc) lia qojoa.
(2) Coefficient e tsitsitseng ea likhohlano. Friction coefficient ke index ea bohlokoa ka ho fetisisa ea ts'ebetso ea thepa efe kapa efe ea likhohlano, e amanang le matla a brake a brake pads. Ts'ebetsong ea braking ka lebaka la mocheso o hlahisoang ke likhohlano, ho eketseha ha mocheso oa ho sebetsa, lisebelisoa tse akaretsang tsa brake pad friction li angoa ke mocheso, coefficient ea likhohlano e qala ho theoha. Lits'ebetsong tse sebetsang, likhohlano li tla fokotsoa, ka hona ho fokotsa phello ea braking. Thepa ea likhohlano ea li-brake pads tse tloaelehileng ha e ea hola, 'me khokahanyo e holimo haholo, e bakang mabaka a sa bolokehang joalo ka tahlehelo ea tsela, ho cha, le ho hohla ha li-brake disc nakong ea braking. Esita le haeba mocheso oa "brake disc" o fihla ho likhato tse 650, coefficient ea friction ea ceramic brake pad e ntse e le ka 0.45-0.55, e ka netefatsang hore koloi e na le ts'ebetso e ntle ea braking.
(3) Li-ceramics li na le botsitso bo botle ba mocheso le conductivity e tlaase ea mocheso, ho hanyetsa ho apara hantle. Mocheso oa ts'ebeliso ea nako e telele ke likhato tse 1000, tse etsang hore ceramic e tšoanelehe bakeng sa litlhoko tse phahameng tsa ts'ebetso ea lisebelisoa tse fapaneng tse phahameng tsa brake, 'me e ka fihlela litlhoko tsa tekheniki tsa lebelo le phahameng, polokeho le khanyetso e phahameng ea li-brake pads.
(4) E na le matla a matle a mochini le thepa ea 'mele. E khona ho mamella khatello e kholo le matla a ho kuta. Lihlahisoa tsa lisebelisoa tsa friction ka har'a kopano pele li sebelisoa, ho na le tlhokahalo ea ho cheka, ho kopanya le lisebelisoa tse ling tsa mechine, e le ho etsa kopano ea brake pad. Ka hona, hoa hlokahala hore thepa ea likhohlano e tlameha ho ba le matla a lekaneng a mochine ho netefatsa hore ha ho na tšenyo le ho arohana nakong ea ho sebetsa kapa ho sebelisoa.
(5) E na le mocheso o tlase haholo oa mocheso. Ebang ke moloko oa pele oa lihlahisoa tsa ceramic tsa M09 kapa moloko oa bone oa li-brake pads tsa TD58, e ntse e ka etsa bonnete ba hore koloi e na le ts'ebetso e ntle ea braking ho netefatsa polokeho, 'me ketsahalo ea ho fokotsa mocheso oa li-brake pads e nyenyane haholo. .
(6) Ntlafatsa ts'ebetso ea li-brake pads. Ka lebaka la ho qhalana ka potlako ha mocheso oa thepa ea ceramic, coefficient ea eona ea likhohlano e phahame ho feta ea li-brake pads ha ho etsoa mariki.
(7) Tšireletseho. Li-brake pad li tla hlahisa mocheso o phahameng hang-hang ha ho beoa mariki, haholo-holo ka lebelo le phahameng kapa ho qhomisoa ka tšohanyetso. Ka mocheso o phahameng, coefficient ea khohlano ea letlapa la friction e tla fokotseha, e bitsoang ho bola ha mocheso. Ho bola ho tlase ha mocheso oa li-brake pads tse tloaelehileng, boemo ba mocheso o phahameng le mocheso oa oli oa brake nakong ea ts'ohanyetso li etsa hore brake e liehe, esita le tahlehelo ea matla a ts'ireletso.
(8) Matšeliso. Lipontšong tsa matšeliso, beng ba matlo ba atisa ho ameha haholo ka lerata la li-brake pads, ha e le hantle, lerata le lona ke bothata boo li-brake pads tse tloaelehileng li sa kang tsa khona ho li rarolla ka nako e telele. Lerata le hlahisoa ke khohlano e sa tloaelehang pakeng tsa poleiti ea friction le disc friction, 'me mabaka a tlhahiso ea eona a rarahane haholo, matla a braking, mocheso oa brake disc, lebelo la koloi le maemo a leholimo e ka ba sesosa sa lerata.
Ho feta moo, lisosa tsa lerata ka mekhahlelo e meraro e fapaneng ea ho qala braking, ts'ebetsong ea braking le ho lokolloa ha braking li fapane. Haeba maqhubu a lerata a pakeng tsa 0 le 550Hz, koloi e ke ke ea utluoa, empa haeba e feta 800Hz, ho hlakile hore mong'a lona a ka utloa lerata la brake.
(9) Litšobotsi tse ntle tsa thepa. Li-brake pads tsa ceramic tse sebelisang likaroloana tse kholo tsa graphite / koporo / ceramics tse tsoetseng pele (tse seng asbestos) le semi-metal le lisebelisoa tse ling tsa theknoloji e phahameng tse hanyetsanang le mocheso o phahameng, ho hanyetsa ho roala, ho tsitsisa mariki, ho lokisa tšenyo ea brake disc, ts'ireletso ea tikoloho, ha ho lerata le lelelele. bophelo ba ts'ebeletso le melemo e meng, ho hlola li-brake pads tsa setso ho lisebelisoa le liphoso tsa ts'ebetso hajoale ke lipeipi tse tsoetseng pele tsa lefatše tse tsoetseng pele tsa maraki a ceramic. Ntle le moo, bolo ea ceramic ea slag e tlase, ntlafatso e ntle, 'me ho roala habeli le lerata la li-brake pads li ka fokotsoa.
(10) Bophelo bo bolelele ba tšebeletso. Bophelo ba ts'ebeletso ke sesupo seo re amehileng haholo ka sona, bophelo ba tšebeletso ea li-brake pads tse tloaelehileng bo ka tlase ho lik'hilomithara tse 60,000, 'me bophelo ba tšebeletso ea li-brake pads tsa ceramic bo feta lik'hilomithara tse 100,000. Ke hobane thepa e ikhethang ea foromo e sebelisoang ho li-brake pads tsa ceramic ke mefuta e 1 ho isa ho e 2 feela ea phofo ea electrostatic, 'me lisebelisoa tse ling ke lisebelisoa tse seng tsa motlakase, e le hore phofo e tla nkoa ke moea ka motsamao oa koloi, 'me e ke ke ea khomarela lebili ama botle ba lebili. Bophelo ba thepa ea ceramic bo phahame ho feta 50% ho feta ba semi-metal e tloaelehileng. Ka mor'a tšebeliso ea li-brake pads tsa ceramic, ho ke ke ha e-ba le ho phunya (ke hore, li-scratches) holim'a disk ea brake, e leng ho eketsang bophelo ba tšebeletso ea koloi ea pele ea koloi ka 20%.
