Tse ka hare
Li-brake li na le boikarabelo ba ho fetola matla a kinetic ho mocheso. 'Me mocheso ona o qhaloa holim'a disc le li-brake pads.
Ho tloha khale, li-brake tsa disc li ile tsa hlahisoa ka 1953 ka koloing. Ka mor'a moo li ne li entsoe ka tšepe e entsoeng ka chrome ho mamella mocheso ka litšenyehelo tsa coefficient of friction. E ne e le mathoasong a lilemo tsa bo-1970 moo li-discs, tse neng li tlatsitsoe qalong, li ne li phunngoa ka li-ducts tsa moea. Joale bophara le botenya lia eketseha.
Li-discs tsa tšepe li nkeloa sebaka ke li-disk tsa carbon; li-carbon discs li na le molemo oa boima ba 'mele (linako tse 2 tse bobebe ho feta tšepe) mme haholo-holo ka hore ha li na ho fokotseha ha katleho ho itšetlehile ka mocheso. U lokela ho tseba hore ha re bua ka li-carbon discs, ha e le hantle ke motsoako oa likhoele tsa ceramic le carbon.
Lisebelisoa tsa mariki
Tsena ke li-pads tse kopanang le brake disc ebe li pshatla sethuthuthu. Lesela la tsona e ka ba tšepe e sintered (e kentsoeng) kapa ea manyolo (ceramic).
Spacers e lokela ho khethoa ho ea ka mofuta oa rim - tšepe e entsoeng ka tšepe, tšepe kapa tšepe e sa hloekang - ebe ho latela mofuta oa sethuthuthu, ho khanna, le ho sebelisa u batla ho etsa ho eona.
Ea tlhaho: hangata tsa pele, li entsoe ka likhoele tsa aramid (mohlala, kevlar) le graphite. Ha ba na mabifi ho feta tšepe 'me ba apara li-discs tse fokolang.
Hangata li khothaletsoa bakeng sa ts'ebeliso ea litoropo / litsela tse kholo moo mariki a sebelisoang ka mokhoa o itekanetseng.
Sintered tšepe: Li entsoe ka li-powders tsa tšepe (boronse, koporo, tšepe) le likhoele tsa ceramic le graphite, kaofela li entsoe ka chipboard ka mocheso o phahameng / khatello. E boloketsoe likoloi tsa lipapali / metsi, e fana ka braking e matla ho feta ha e ntse e sa amehe haholo ka mocheso o feteletseng. Haeba li sa khathale hangata, li ba mabifi ho chesa. Ka hona, ke habohlokoa ho hlahloba hore na li-discs li etselitsoe ho tšehetsa lipoleiti tsa tšepe tse sintered, ho seng joalo li-discs li tla senngoa.
Li-pads li boetse li fapane ho ea ka tšebeliso ea tsona / mocheso: tsela 80 ° ho 300 °, lipapali 150 ° ho 450 °, mabelo a 250 ho 600 °.
Ela hloko! lipoleiti ha li sebetse hantle ho fihlela li fihla mocheso oa ho sebetsa. Ka hona, ha se hangata tsela e fihlang ho 250 ° ... ho bolelang hore mabala a mabelo a ke ke a sebetsa hantle ho feta litsela tsa tšebeliso ea letsatsi le letsatsi.
Khafetsa ea phetoho
Bophelo ba li-pads bo tla itšetleha ka sebopeho sa bona, empa haholo-holo ho mofuta oa hau oa ho khanna le makhetlo ao u sebelisang mariki ka ona. Ho lebella le braking butle-butle ho tla eketsa bophelo ba li-gaskets. Ke ile ka fetola lipache feela kamora lik'hilomithara tse 18 ... "ha u lieha, u lekoala" 😉
Brake disk
Li-brake pads li loma li-discs tsa tšepe.
Hangata li-disk tsena li na le likarolo tse tharo:
- pina: e entsoe ka tšepe / tšepe e sa hloekang kapa tšepe e entsoeng ka tšepe, ea fela, e chekoa lik'hilomithara tse fetang.
- Khokahano: E fana ka khokahano lipakeng tsa tsela ea sefofane le fretboard ka mehele kapa li-rivets. Papali e hlahisa lerata le sebetsang.
- fret/ Ketso ya ho ferekana: setshehetso se kopanyang sethuthuthu le tsela ya mariki.
Ho latela palo ea likarolo le sebopeho sa tsona, re bua ka li-disks:
- E tsitsitseng: pina ea brake e entsoeng ka thepa e tšoanang le ea fret
- Semi-floating: li-frets le lipina li entsoe ka lisebelisoa tse fapaneng 'me li hloekisoa.
- Floating: seporo sa mariki se entsoe ka lintho tse ling ntle le ho ferekana; ka bobeli li hokahane ka mehele e bohareng e sieang bolokolohi ba ho tsamaea ho disc: mofuta o tsoetseng pele ka ho fetesisa oa brake disc. Sena se lumella ho se phethahale ha lebili le ho beleha tumello ho tlatsoa. Lisebelisoa tsa setsi li boetse li lumella pina hore e ikemisetse ka tsela e molemo ka ho fetisisa e amanang le liphahlo.
Tšepe ea "brake disc" e etsa qeto ea hore na ho tla sebelisoa liphaephe. Diski ea tšepe e sa hloekang e tla sebelisa lipoleiti tsa tšepe. The cast iron disc e tla sebelisa lipoleiti tsa manyolo. Ka lehlakoreng le leng, disc ea tšepe ea tšepe ha e mamelle li-spacers tsa tšepe tse sintered.
Li-discs li ka chesa ho fihlela ho 500 ° C! ho tseba hore disc ea tšepe e sa hloekang e holofala ka holimo ho 550 °.
Diski e ea fela 'me e fetoha ka tloaelo ka mor'a lihlopha tse 3-5 tsa shims.
U se ke ua lebala ho hlahloba ponahalo ea bona ka kakaretso le ponahalo ea li-microcracks tse ka khonehang.
U lokela ho hlokomela hore disc e tšesaane haholo e chesa ka potlako; ho sebetsa ha eona le mamello ea eona joale lia fokotseha.
Brake calipers
E phaphametseng: hlahloba le ho tlotsa li-axle tsohle, fetola melumo ha ho hlokahala.
E tsitsitseng: hlahloba ho lutla, laola axis ea li-pads
Keletso: Hloekisa li-disc le li-clamp ka metsi a sesepa.
Brake hose
Hangata li entsoe ka rabara. Joale ho lekane ho hlahloba hore ha ho na mapetsong ka lebaka la lilemo, ho tiea le boemo ba lisebelisoa tsa brake.
Ho na le li-hoses tse nang le mokokotlo oa Teflon le braid ea tšepe e sa hloekang ebe e koaheloa ka sheath e sireletsang ea PVC.
Moqomo oa master
Lekola ponahalo ea eona ka kakaretso, boteng ba ho lutla ho ka bang teng kapa metsi (pipe, khalase ea mahlo, piston seal) le bophahamo ba boemo ba mokelikeli oa brake. Ho bohlokoa ho fetola brake fluid ka mor'a lilemo tse ling le tse ling tse peli tabeng ea DOT4. selemo le selemo tabeng ea DOT5.
Tlhahiso:
Sheba boemo ba liphahlo kamehla. Li-pads li bitsa li-euro tse fetang 15, empa rekoto e bitsa li-euro tse fetang 350! U tlameha ho fetola libuka tsa li-discs ka bobeli ka nako e le 'ngoe (le haeba e' ngoe ea lipapali e ntse e bonahala e le boemong bo botle).
Joalo ka karolo efe kapa efe e ncha, tlhokomelo e khethehileng e tlameha ho nkuoa nakong ea lik'hilomithara tse 'maloa tsa pele ho fa li-pads nako ea ho ikamahanya le li-discs. Ka bokhuts'oane, ts'ebeliso e bonolo ea mariki: braking e nyane hape e bonolo.
Rekota litheko:
Tlhokomeliso, li-discs tse letšehali le tse nepahetseng li fapane 'me hangata li fapana ho tloha khale ho ea ho e' ngoe.
Ho boetse ho na le lirifi tse feto-fetohang ka litheko tse theohang ka tlase ho li-euro tse 150. Empa hey, u se ke ua lebella boleng bo tšoanang!
Litheko tsa libukana:
Lisebelisoa tsa Fora: € 19 (Dafy Moto)
Ho Carbonne Lorraine: li-euro tse 38 (ref: 2251 SBK-3 ka pele bakeng sa 1200).
Joale, haeba u nka qeto ea ho fetola ntho e 'ngoe le e' ngoe ka nako e le 'ngoe' me u kenyelletse mosebetsi, ho tla u jella chelete e ka bang € 100 ho kenyeletsa le VAT. (ka pele phanele sete: 2 * 158,53 FHT, ka morao sekoahelo sete: 142,61 FHT, ntseng bo eketseha sephutheloana 94,52 FHT).
