Moralo oa multiplate friction clutch le eona le molao-motheo oa ts'ebetso

Multi-plate friction clutch ke mofuta oa mochine oa phetisetso ea torque o nang le pakete ea li-friction le li-disk tsa tšepe. Nako e fetisoa ka lebaka la matla a khohlano a hlahang ha li-discs li hatelloa. Li-clutch tsa lipoleiti tse ngata li sebelisoa haholo litsing tse fapaneng tsa phetisetso ea likoloi. Nahana ka sesebelisoa, molao-motheo oa ts'ebetso, hammoho le melemo le melemo ea mekhoa ena.

Molao-motheo oa ts'ebetso ea clutch

Mosebetsi o ka sehloohong oa clutch ea lipoleiti tse ngata ke ho kopanya hantle le ho khaola li-input (drive) le lihlahisoa (tse tsamaisoang) ka nako e nepahetseng ka lebaka la matla a khohlano pakeng tsa li-disks. Tabeng ena, torque e fetisoa ho tloha shaft e 'ngoe ho ea ho e' ngoe. Li-discs li hatelloa ke khatello ea mokelikeli.

Ka kopo hlokomela hore boleng ba torque e fetisitsoeng bo boholo, bo matla ho feta libaka tsa ho kopana tsa li-discs. Nakong ea ts'ebetso, clutch e ka 'na ea thella,' me shaft e khannoang e potlakisa hantle ntle le ho sisinyeha kapa ho sisinyeha.

Phapang e ka sehloohong ea mochine oa li-multi-disk ho tloha ho ba bang ke hore ka ho eketseha ha palo ea li-disks, palo ea libaka tsa ho kopana e eketseha, e leng se etsang hore ho khonehe ho fetisetsa torque e eketsehileng.

Motheo oa ts'ebetso e tloaelehileng ea clutch ea likhohlano ke ho ba teng ha lekhalo le feto-fetohang pakeng tsa li-discs. Nako ena e tlameha ho lumellana le boleng bo behiloeng ke moetsi. Haeba lekhalo pakeng tsa li-clutch discs le le ka tlase ho boleng bo boletsoeng, li-clutches li lula li le boemong ba "compressed" 'me li senyeha ka potlako ho latela. Haeba sebaka se le seholo, ho thella ha clutch ho bonoa nakong ea ts'ebetso. 'Me tabeng ena, ho apara ka potlako ho ke ke ha qojoa. Tokiso e nepahetseng ea li-clearance lipakeng tsa li-coupling ha ho lokisoa khokahano ke senotlolo sa ts'ebetso ea eona e nepahetseng.

Kaho le likarolo tse kholo

The multi-plate friction clutch ke ka sebopeho sephutheloana sa tšepe le alternating friction discs. Palo ea bona ka ho toba e itšetlehile ka hore na torque e lokela ho fetisoa pakeng tsa li-shafts.

Kahoo, ho na le mefuta e 'meli ea li-washer ka har'a clutch - tšepe le likhohlano. Ke phapang efe pakeng tsa bona 'Nete ke hore mofuta oa bobeli oa pulley o na le seaparo se khethehileng se bitsoang "friction". E entsoe ka lisebelisoa tse phahameng tsa likhohlano: li-ceramics, li-composite tsa carbon, khoele ea Kevlar, joalo-joalo.

Li-discs tse tloaelehileng haholo tsa likhohlano ke li-discs tsa tšepe tse nang le lera la likhohlano. Leha ho le joalo, ha se kamehla li thehiloeng ka tšepe; ka linako tse ling likarolo tsena tse kopanyang li entsoe ka polasetiki e tšoarellang. Li-discs li khomaretsoe ho hub ea shaft ea koloi.

Li-disc tse tloaelehileng tsa tšepe tse se nang frictionless li kenngoa ka har'a moqomo o kopantsoeng le shaft e khannoang.

Clutch e boetse e na le piston le seliba se khutlang. Tlas'a ketso ea khatello ea mokelikeli, piston e hatella pakete ea disc, e etsa hore ho be le matla a khohlano pakeng tsa bona le ho fetisa torque. Ka mor'a hore khatello e lokolloe, selemo se khutlisetsa piston 'me clutch e lokolloa.

Ho na le mefuta e 'meli ea li-clutch tse nang le lipoleiti tse ngata: tse omeletseng le tse metsi. Mofuta oa bobeli oa sesebelisoa o tlatsitsoe ka oli ka mokhoa o itseng. Lubrication ke ea bohlokoa bakeng sa:

• ho senya mocheso o sebetsang haholoanyane;
• Lubrication ea likarolo tsa clutch.

Metsi a mangata a clutch a na le tšitiso e le 'ngoe - coefficient e tlase ea likhohlano. Bahlahisi ba lefella bofokoli bona ka ho eketsa khatello ea li-discs le ho sebelisa lisebelisoa tsa morao-rao tsa likhohlano.

Melemo le likotsi

Melemo ea clutch ea multiplate friction:

• compactness;
• Ha u sebelisa clutch ea lipoleiti tse ngata, litekanyo tsa yuniti li fokotsehile haholo;
• phetiso ea torque ea bohlokoa ka litekanyo tse nyane tsa mochini (ka ho eketsa palo ea li-disks);
• boreleli ba mosebetsi;
• monyetla oa ho hokela shaft drive le shaft driven coaxially.

Leha ho le joalo, mochine ona ha o na mathata. Ka mohlala, li-disc tsa tšepe le tsa likhohlano li ka chesa nakong ea ts'ebetso. Ka li-clutch tsa lipoleiti tse ngata tse metsi, coefficient of friction e boetse e fetoha ha viscosity ea lubricant e fetoha.

Coupling kopo

Li-clutch tse nang le lipoleiti tse ngata li sebelisoa haholo likoloing. Sesebelisoa sena se sebelisoa lits'ebetsong tse latelang:

• clutch (ka CVTs ntle le torque converter);
• Phetiso ea othomathiki (phetiso ea othomathiki): Clutch ea othomathiki ea phetiso e sebelisetsoa ho fetisetsa torque ho sete ea lisebelisoa tsa polanete.
• Lebokose la liroboto: Pakete ea dual clutch disc e ka lebokoseng la liroboto e sebelisetsoa ho fetoha ka lebelo le phahameng.
• Sistimi ea ho khanna ka mabili ohle: sesebelisoa sa likhohlano se hahiloe ka har'a nyeoe ea phetisetso (clutch e hlokahala mona ho notlela phapang ea bohareng);
• Phapang: sesebelisoa sa mochini se etsa mosebetsi oa ho thibela ka botlalo kapa ka mokhoa o itseng.
