Sebaka sa ho kenya ke lesoba la tataiso le boretsoeng karolong e tsamaellanang ea cylinder block kapa cylinder head, eo hangata e entsoeng ka tšepe e entsoeng ka nickel-chromium alloy cast or cold shock alloy cast iron.
1) Li-tappets tse tloaelehileng Ho na le mefuta e meraro ea lipompo tse tloaelehileng: lipompo tse bōpehileng joaloka fungus, li-cylindrical tappets le li-roller type tappets. Li-tappets tse bōpehileng joaloka fungus le li-cylindrical li ka fokotsa boima ba tsona ka lebaka la sebopeho se sekoti; li-tappets tsa mofuta oa li-roller li hokahane le mohala ka lebaka la foromo ea ho ikopanya, 'me li-roller li ka pitika ka bolokolohi, tse ka fokotsang ho khathala. Li-tappets tse tloaelehileng ke meaho e thata 'me e ke ke ea felisa ho hlaka ha valve ka bo eona. Ka hona, lienjineri tse sebelisang li-tappets tse tloaelehileng li tlameha ho lokisa ho hlaka ha valve.
2) Litšobotsi tsa lipompo tsa hydraulic: Monyetla o moholo oa lipompo tsa hydraulic holim'a lipompo tse tloaelehileng ke hore li ka felisa tumello ea valve ea enjene ntle le ho lokisa tumello ea valve; ka nako e ts'oanang, li-tappets tsa hydraulic li ka boela tsa fokotsa lerata la phetisetso ea mochine oa valve ea enjene.
3) Sebopeho sa "hydraulic tappet": 'mele oa' mele o kenngoe ka har'a 'mele o le mong ka sekoahelo se ka holimo le silinda,' me o khona ho ea holimo le tlase ka lesoba la hlooho ea silinda. Sekoti se ka hare le selikalikoe se ka ntle sa letsoho li felile 'me li fatše. Selika-likoe se ka ntle se ts'oana le lesoba la tataiso ka har'a teipi, 'me lesoba le ka hare le ts'oanela plunger. Ka bobeli li khona ho tsamaea li amana. Seliba se lefang se kentsoe botlaaseng ba hydraulic cylinder ho hatella valve ea bolo khahlano le setulo sa valve sa plunger. E ka boela ea boloka bokaholimo ba tappet bo amana haufi-ufi le bokaholimo ba cam ho felisa ho hlaka ha valve. Ha valve ea bolo e koala lesoba le bohareng la plunger, tappet e ka aroloa ka likamore tse peli tsa oli, kamore e ka holimo ea khatello e tlaase ea oli le kamore e tlaase ea oli e tlaase; ka mor'a hore valve ea bolo e buloe, ho thehoa kamore.
4) Molao-motheo o sebetsang oa tappet ea hydraulic Ha groove ea oli ea annular holim'a 'mele oa tappet e tsamaisana le lesoba la oli le oblique holim'a hlooho ea silinda, oli e ka har'a sistimi ea lubrication ea enjene e phalla ka har'a sekoti sa oli ea khatello e tlase ka lesoba la oli le oblique le annular. khaba ea oli. Sebaka sa bohlokoa se ka morao ho 'mele oa tappet se ka lebisa oli ka har'a sekoti sa oli e tlaase ka holim'a plunger. Ha cam e potoloha mme 'mele oa tappet le plunger li theohela tlase, oli e ka kamoreng ea oli e nang le khatello e phahameng ea hatelloa mme khatello ea oli ea phahama. Hammoho le selemo sa matšeliso, belofo ea bolo e hatelloa ka thata holim'a setulo sa valve se tlase sa plunger. Ha kamore ea oli e nang le khatello e phahameng e arohane le kamore ea oli ea khatello e tlaase. Kaha mokelikeli o ke ke oa hatelloa, theipi eohle e theohela fatše joaloka cylinder, e sutumelletsa kutu ea valve e bulehile. Ka nako ena, groove ea oli ea tappet annular e sisinyehile ka lesoba la oli ea oblique, 'me ho kenngoa ha oli ho emisa. Ha tappet e fihla setsing sa eona se shoeleng se ka tlaase 'me e qala ho fallela holimo, tlas'a ketso ea mocheso o ka holimo oa li-valve le khatello e tlaase ea cam, kamore ea oli ea khatello e phahameng e koetsoe 'me valve ea bolo e ke ke ea buleha. Theipi ea hydraulic e ntse e ka nkuoa e le tappet e thata ho fihlela e phahama. Ho fihlela cam e le selikalikoe sa motheo 'me valve e koetsoe. Ka nako ena, oli ea khatello e karolong e ka sehloohong ea oli ea hlooho ea cylinder e kena ka kamoreng ea oli ea khatello e tlaase ea tappet ka lesoba la oli le sekametseng. Ka nako e ts'oanang, khatello ea oli ka kamoreng ea khatello e phahameng ea theoha, 'me seliba sa matšeliso se sutumelletsa plunger holimo. Oli ea khatello e tsoang ka kamoreng ea oli e tlaase e sutumelletsa ho bula valve ea bolo ka kamoreng ea oli e nang le khatello e phahameng, e le hore likamore tse peli li kopane 'me li tlatsoe ka oli. Ka nako ena, bokaholimo ba tappet bo ntse bo amana haufi-ufi le khamera. Ha valve e futhumatsoa 'me e atolosoa, plunger le hydraulic cylinder li tsamaisana ho ea ka tsela ea axial,' me oli e ka kamoreng ea oli e nang le khatello e phahameng e ka phunyeletsa ka kamoreng ea oli e nang le khatello e tlaase ka lekhalo pakeng tsa silinda ea hydraulic. le plunger. Ka hona, ha u sebelisa lipompo tsa hydraulic, ha ho na tlhoko ea ho boloka tumello ea li-valve.
2. Mosebetsi oa molamu o sutumetsang ke ho fetisetsa ho phunyeletsa ho fetisoa ho tloha camshaft ka tappet ho ea letsohong la rocker ka mochine oa ho tsamaisa moea oa valve ea holimo le camshaft e ka tlaase. The push rod ke karolo e tenyetsehang ka ho fetisisa le e tšesaane ka tereneng ea li-valve. Sebopeho sa eona se akaretsang se kenyelletsa likarolo tse tharo: hlooho ea bolo e ka holimo ea concave, hlooho ea bolo e tlaase ea convex le molamu o sekoti. The push rod hangata e entsoe ka phala e batang ea tšepe e se nang seamless, 'me e meng e entsoe ka duralumin. Sesepa se tiileng sa tšepe hangata se etsoa ka kakaretso ka tšehetso ea spherical, ebe se phekoloa mocheso; lipheletsong tse peli tsa duralumin material solid putter li na le litšehetso tsa tšepe, 'me lipheletsong tse ka holimo le tse ka tlaase li kopantsoe le shaft; hlooho ea bolo ea pele le The shaft e entsoe ka kakaretso, 'me lipheletsong tse peli tsa ho qetela li kopantsoe le shaft ka ho tjheseletsa le ho hatisa. Le hoja ho na le phapang e itseng ea sebopeho sa sebopeho, litlhoko tsa molamu oa sutu li tšoana, ke hore, boima bo bobebe le boima bo phahameng. Tlas'a maemo a tloaelehileng, e le ho etsa bonnete ba ho lekana hantle ha tappet, letsoho la rocker le tappet, lenonyeletso la tšepe la concave spherical le cheselitsoe pheletsong e ka holimo ea molamu oa ho sututsa ho ts'oana le hlooho ea bolo ea sekoti se fetolang letsoho la rocker; Ka soketeng ea bolo ea concave.
3. Mosebetsi o ka sehloohong oa letsoho la rocker ke ho fetola tataiso ea phetisetso ea matla. Letsoho la rocker le lekana le sebopeho sa lever, se fetisetsang matla a molamu o sutumetsang pheletsong ea mohatla oa kutu ea valve ho sutumelletsa valve hore e bule; karo-karolelano ea bolelele ba matsoho a mabeli (e bitsoang "rocker arm ratio)" e sebelisetsoa ho fetola phahamiso ea valve, letsoho la "valve rocker" Ka kakaretso, le etsoa ka mokhoa oa bolelele bo sa lekanang. Letsoho le lehlakoreng la valve le bolelele ba 30% ho 50% ho feta letsoho le lehlakoreng la molamu o sutumetsang, e le hore ho ka fumanoa phahamiso e kholoanyane ea valve.
