Tse ka hare
Ho khetha li-brake pads tse nepahetseng bakeng sa koloi ea hau ho itšetlehile ka hore na li nkeloa sebaka ke eng, hore na li entsoe ka thepa efe, le hore na li nkiloe ka mokhoa o tšepahalang.
Sistimi ea sejoale-joale ea braking ea likoloi e tsoetse pele haholo. Ho tloha ho li-brake pads tsa khale le litsamaiso tsa meropa tse sebelisoang ka mochini ho ea ho ABS ea sejoale-joale e laoloang ke komporo, likarolo tsohle tsa sistimi ea mariki lia khathala ha nako e ntse e ea 'me li hloka ho nkeloa sebaka. Likarolo tse senyehang haholo ke li-brake pads. Le hoja kamehla ho le molemo ho khomarela likarolo tsa tsamaiso ea brake ea moetsi oa thepa ea pele (OEM), ho khetha li-brake pads tse nepahetseng ho ntse ho rarahana le ho feta ka likhetho tse ngata, mefuta le mekhoa e teng moo.
Li-brake pads li lokela ho nkeloa sebaka ka linako tsohle pele li khathala le ho latela litlhahiso tsa moetsi oa koloi ea hau ho boloka ts'ebetso e nepahetseng ea ho emisa. Sena se tla fokotsa tšenyo ea likarolo tse ling tsa bohlokoa tsa brake system joalo ka li-brake calipers le rotor. Haeba li-brake pads li ntse li felile 'me u hloka ho khetha li-brake pads tse nepahetseng, ipotse lipotso tsena tse 3 tse qaqileng:
1. Li-brake pads li lokela ho nkeloa sebaka neng?
Baetsi ba likoloi ba bangata ba khothalletsa hore ho behoe li-brake pad sebakeng sa lik’hilomithara tse ling le tse ling tse 30,000 40,000 100,000 120,000 XNUMX —’me ha e le hantle nako le nako ha u fetola litha- thaere koloing ea- hao. Lithaere le mariki li sebetsa 'moho ho thusa ho emisa koloi ea hau, kahoo ke ntho e utloahalang ho fetola li-brake pads le lieta tsa koloi ea hau ka nako e le 'ngoe. Ka ho fetola li-brake pads pele li fela ka ho feletseng, u ka qoba ho fetola rotor ea brake - karolo ea li-brake pads e ama ho thibela lebili hore le se ke la potoloha. Li-rotor tsa Brake li lokela ho nkeloa sebaka ke lipotoloho tse ling le tse ling tse peli kapa tse tharo kapa lik'hilomithara tse XNUMX ho isa ho tse XNUMX. Ho na le matšoao a 'maloa a tloaelehileng ao bakhanni ba likoloi ba ka a utloang le ho ikutloa a tla ba hlokomelisa ka tlhokahalo ea ho khutlisa li-brake pad tsa bona kapele ho feta hamorao.
Brake squeal: Haeba u hatella brake pedal 'me u utloa lerata le leholo le lla, sena se bakoa ke hore li-brake pads li apere tse tšesaane haholo. Ka ho khetheha, letšoao la ho roala le tla ama "brake disc" ha seaparo sa pad se feta 80%. Haeba li-brake pads li sa nkeloe sebaka hang ka mor'a hore u utloe lerata lena, letšoao la ho apara le tla cheka ka har'a rotor, le hlokang ho nkeloa sebaka hangata.
Litšusumetso tsa Brake pedal: Haeba u tobetsa "brake pedal" 'me u utloa ho tsitsipana, sena ke sesupo se seng se tloaelehileng sa ho roala mariki. Leha ho le joalo, e ka boela ea e-ba letšoao la rotor e sothehileng kapa mathata a tsamaiso ea ABS, kahoo ho e hlahloba ke setsebi sa mochine ke khopolo e ntle.
2. Ke lintlha life tseo u lokelang ho li sheba ka har'a li-brake pads?
Ha u batla li-brake pads tse ncha, ho na le lintho tse 7 tseo u lokelang ho nahana ka tsona ho fumana li-brake pads tsa koloi ea hau. Mofuta oa brake pad o o hlokang o ipapisitse le mokhoa oa hau oa ho khanna le maemo. Ka mohlala, li-brake pads tse etselitsoeng ho tsamaea li ke ke tsa tlameha ho sebetsana le mocheso o phahameng, ha liphahlo tsa likoloi tse sebetsang hantle, ka lehlakoreng le leng, li tla hloka ho mamella ho longoa ho chesang.
Litšobotsi tsa boemo ba leholimo: Li-brake pad tse ntle li lokela ho sebetsa maemong a leholimo leha e le afe, ebang ke omileng, o metsi, a litšila, a futhumetse kapa a bata.
Ho loma ho batang le ho longoa ho chesang: Brake pad ea hau e lokela ho sebetsa kamoo e reriloeng kateng 'me e fane ka khohlano e loketseng, ebang ho chesa kapa ho bata.
Maximum Operating Temperature (MOT): Ena ke mocheso o phahameng ka ho fetisisa oo brake pad e ka fihlang ho eona pele e ba e sa bolokehang ka lebaka la ho arohana.
Karabelo ea friction ho thempereichara: Sena se lekanyetsoa ho profil ea friction, ho ela hloko hore na u hloka ho sebelisa matla a makae ho pedal ho fumana karabo e ts'oanang tlas'a braking ea tšohanyetso joalo ka tlas'a braking e tloaelehileng.
Bophelo ba tšebeletso ea pad le rotor: Ka bobeli brake pad le rotor li ka roaloa. U tlameha ho nahana ka nako e telele ea liphahlo tse etselitsoeng ho tšoarella hammoho le rotor ha u kopanya li-brake pads.
Lerata le ho thothomela: U tlameha ho nahana hore na lerata le leholo hakae, ho thothomela, esita le maikutlo a maoto a bakoang ke ho hatella brake pad.
Boemo ba lerole: Li-brake pads li ka bokella lerōle, ebe le khomarela lebili.
3. Ho na le mefuta efe ea li-brake pads?
Joalokaha re boletse ka holimo, keletso e molemo ka ho fetisisa ea ho fetola li-brake pads ke ho latela litlhahiso tsa likarolo tsa moetsi kamehla. Maemong a mangata, sena se bolela hore o tla kopa li-brake pads tsa OEM. Ho ipapisitse le mofuta oa koloi eo u nang le eona, li-brake pads tsa OEM li kanna tsa etsoa ho tsoa ho e 'ngoe ea lisebelisoa tse tharo tse ikhethang. Mefuta e 3 e atileng haholo ea lisebelisoa tsa brake pad e thathamisitsoe ka tlase:
1. Organic brake pads
Li-brake pads qalong li ne li entsoe ka asbestos, ntho e thata empa e le chefo e 'nileng ea amahanngoa le mefuta e sa tšoaneng ea mafu a matšoafo. Ha asbestos e ne e thibetsoe, li-brake pads tse ngata li ile tsa qala ho etsoa ka motsoako oa lisebelisoa tse ngata, ho akarelletsa le carbon, khalase, rabara, likhoele le tse ling. Li-brake pads hangata li khutsitse ebile li bonolo. Bothata bo boholo ke hore li phela nakoana. Hangata u tla fumana li-pads tsa OEM tsa organic bakeng sa likoloi tse majabajaba tse bobebe.
2. Semi-metallic brake pads
Likoloi tse ngata tseleng kajeno li sebelisa semi-metallic pads. Semi-metallic brake pad e entsoe ka koporo, tšepe, tšepe le lisebelisoa tse ling tse kopantsoeng le mafura a graphite le lisebelisoa tse ling tse thusang ho fokotsa mocheso. Mefuta ena ea li-brake pads e atisa ho sebelisoa e le tharollo ea OEM bakeng sa likoloi tse boima ka lebaka la bokhoni ba tsona ba ho tšoarella nako e telele le ho fokotsa likhohlano, ho thusa ho emisa likoloi tse boima, literaka le li-SUV ka katleho.
3. Li-brake pads tsa ceramic
Brake pad e ncha ka ho fetisisa 'marakeng ke pad ea ceramic. Li-brake pads tsa Ceramic li ile tsa hlahisoa lilemong tsa bo-1980 e le sebaka sa li-pads tsa khale tsa asbestos. Mofuta ona oa brake pad o entsoe ka thepa e thata ea ceramic e kopantsoeng le likhoele tsa koporo. Ka lebaka la moralo oa tsona o ikhethang, li na le ho tšoarella nako e telele ho tse tharo tse kholo mme li sebetsa hantle. Bothata bo habeli. Ntlha ea pele, le hoja li khona ho mamella mocheso o phahameng, ha li sebetse hantle maemong a leholimo a batang kaha thepa e atisa ho petsoha ha e le maemong a batang haholo. Hape ke mofuta o turang haholo oa li-brake pads.
4. Nka sebelisa li-brake pads tsa OEM?
Karabo e bonolo ea potso ena ke che. Ho na le bahlahisi ba bang ba likoloi ba hlokang tšebeliso ea likarolo tsa OEM ho hlompha liwaranti, kahoo u lokela ho buisana le moetsi oa koloi ea hau pele. Leha ho le joalo, lik'hamphani tse 'maloa tsa likoloi li na le likhetho tse lekanang tsa OEM tsa brake pad tse entsoeng ke baetsi ba li-aftermarket. Haeba u batla ho reka aftermarket brake pads, latela melao e meraro ea mantlha:
1. Kamehla reka lets'oao le tšepahalang. Li-brake pad li ka pholosa bophelo ba hau. Ha u batle ho sekisetsa ha u nkela li-brake pads tse entsoeng ke moetsi oa li-aftermarket tse theko e tlaase.
2. Sheba tiisetso. Bahlahisi ba bangata ba li-brake pad (kapa barekisi ba li rekisang) ba fana ka waranti ho li-brake pads tsa bona. Le hoja li etselitsoe ho tsofala ha nako e ntse e ea, haeba li tšehelitsoe ke waranti ea lik'hilomithara, ke pontšo e ntle ea boleng ba likarolo tsa aftermarket.
3. Batla Litifikeiti. Ho na le li-certification tse peli tse akaretsang bakeng sa li-brake pads tse kenyellelitsoeng likarolong tsa aftermarket. Ea pele ke Differential Effectiveness Analysis (D3EA) ’me ea bobeli ke ea Brake Effectiveness Evaluation Procedures (BEEP).
Ho sa tsotellehe hore na u khetha mofuta ofe oa brake pad, ke habohlokoa ho hopola hore ho kenya hantle ke tšobotsi ea bohlokoa ka ho fetisisa. Haeba u batla ho khetha li-brake pads tse nepahetseng, etsa bonnete ba hore u na le setsebi sa mechini se u etsetsang tšebeletso ena.
