Ha batho ba bua ka lithuthuthu tse mabili a mararo le literaka tse bobebe le liveni, hangata ba re selepe sena se phaphametse ka ho feletseng, le hore sele eo e phaphamala. "Full float" le "semi-float" li bolela'ng moo? A re arabeng potso ena e ka tlaase.
Seo ho thoeng ke "full-floating" le "semi-floating" li bolela mofuta oa tšehetso e ntseng e phahama bakeng sa li-axle shafts tsa likoloi. Joalo ka ha bohle re tseba, halofo ea shaft ke shaft e tiileng e fetisang torque lipakeng tsa phapang le mabili a koloi. Lehlakore la eona le ka hare le hokahane le gear e lehlakoreng ka spline, 'me lehlakore le ka ntle le hokahane le setsi sa lebili la koloi le flange. Kaha halofo ea shaft e hloka ho jara torque e kholo haholo, matla a eona a hlokahala hore a be a phahameng haholo. Ka kakaretso, tšepe ea alloy joalo ka 40Cr, 40CrMo kapa 40MnB e sebelisoa bakeng sa ho tima, ho futhumatsa le ho tima kalafo ea maqhubu a phahameng. Ho sila, mokokotlo o na le boima bo botle, o khona ho mamella torque e kholo, 'me o khona ho mamella mojaro o itseng oa tšusumetso, o ka finyellang litlhoko tsa likoloi tlas'a maemo a sa tšoaneng.
Ho ea ka mefuta e fapaneng ea tšehetso ea li-half shafts, li-half shafts li arotsoe ka mefuta e 'meli: "floating e feletseng" le "semi-floating". Axle e phaphametseng ka botlalo le semi-floating axle eo hangata re buang ka eona e bua ka mofuta oa halofo ea shaft. "Float" mona e bua ka mojaro o kobehang ka mor'a hore molamu oa axle o tlosoe.
Se bitsoang "full-floating half shaft" se bolela hore halofo ea shaft e na le torque feela 'me ha e na nako ea ho khumama. Lehlakore le ka hare la "half shaft" le hokahane le lisebelisoa tsa mahlakoreng a fapaneng ka li-splines, 'me lehlakore le ka ntle le na le poleiti ea flange, e ts'oaroang le hub ea mabili ka liboutu,' me hub ea mabili e kenngoa holim'a axle ka lirolara tse peli tse tapered. dibering. Ka tsela ena, litšisinyeho tse fapa-fapaneng le ho sisinyeha ho mabili, hammoho le boima ba koloi, li fetisoa ho tloha mabiling ho ea ho li-hubs ebe ho ea ho li-axle, tseo qetellong li tsamaisoang ke matlo a li-axle. Li-axle shafts li fetisetsa torque ho tloha ho phapang ho ea ho mabili ho khanna koloi. Ts'ebetsong ena, lipheletsong tse peli tsa halofo ea shaft li na le torque feela ntle le nako ea ho khumama, kahoo e bitsoa "floating e feletseng". Setšoantšo se latelang se bontša sebopeho le ho kenngoa ha halofo ea shaft ea koloi e phaphametseng ka ho feletseng. Sebopeho sa eona sa sebopeho ke hore hub ea mabili e kenngoa holim'a axle ka li-roller bearings tse peli tse tapered, lebili le kenngoa holim'a hub ea mabili, matla a tšehetsang a fetisetsoa ka ho toba ho axle, 'me halofo ea shaft e feta. Li-screw tse robeli li hokahantsoe le hub ebe li fetisetsa torque ho hub, li khanna lebili hore le retelehe.
Half shaft e phaphametseng ka ho feletseng e bonolo ho qhaqha le ho e nkela sebaka, 'me halofo ea shaft e ka ntšoa feela ka ho tlosa liboutu tsa ho lokisa tse behiloeng holim'a poleiti ea flange ea halofo ea shaft. Leha ho le joalo, boima bohle ba koloi ka mor'a ho tlosa halofo ea axle e tšehetsoa ke matlo a li-axle, 'me e ntse e ka emisoa fatše ka botšepehi; bothata ke hore sebopeho se batla se rarahane mme boleng ba likarolo bo boholo. Ke mofuta o sebelisoang haholo likoloing, 'me boholo ba literaka tse bobebe, tse mahareng le tse boima, tse kantle ho tsela le likoloi tsa baeti li sebelisa mofuta ona oa shaft ea axle.
Seo ho thoeng ke semi-floating half shaft se bolela hore halofo ea shaft ha e jare torque feela, empa e boetse e na le nako ea ho khumama. Lehlakore le ka hare la lesela le joalo le hokahane le gear ea mahlakoreng a fapaneng ka li-splines, pheletsong e ka ntle ea axle shaft e ts'ehelitsoe ntlong ea li-axle ka ho bere, 'me lebili le behiloe ka mokhoa o tsitsitseng holim'a cantilever pheletsong e kantle ea leqhubu. thipa ea axle. Ka tsela ena, matla a fapa-fapaneng a sebetsang ka mabili le nako ea ho khumama e hlahisoang e fetisetsoa ka ho toba ho li-shafts tse halofo, ebe ho ea ntlong ea li-axle ka har'a li-bearings. Ha koloi e ntse e matha, li-shafts tsa halofo ha li tsamaise mabili feela ho potoloha, empa hape li khanna mabili ho potoloha. Ho tšehetsa boima bo feletseng ba koloi. Qetello e ka hare ea halofo ea shaft e jara torque feela empa eseng nako ea ho kobeha, ha pheletso e ka ntle e na le torque le motsotso o felletseng oa ho kobeha, kahoo e bitsoa "semi-floating". Setšoantšo se latelang se bontša sebopeho le ho kenngoa ha semi-axle e phaphametseng ea koloi. Sebopeho sa eona sa sebopeho ke hore pheletso e ka ntle e tsitsitse ebile e ts'ehelitsoe holim'a moqomo oa tapered ka holim'a sefahleho le senotlolo le hub, 'me matla a ka ntle a axial a khannoa ke moferefere oa tapered. Ho jara, matla a ka hare a axial a fetisetsoa ho bere e tapered ea lehlakoreng le leng la halofo ea shaft ka slider.
Sebopeho sa ts'ehetso sa semi-floating half-shaft se kopane 'me se bobebe ka boima ba' mele, empa matla a halofo ea shaft a rarahane, 'me ho qhaqha le ho kopanya ha ho bonolo. Haeba li-axle shafts li tlosoa, koloi e ke ke ea tšehetsoa fatše. Ka kakaretso e ka sebelisoa feela ho li-vans tse nyane le likoloi tse bobebe tse nang le koloi e nyane, bophara ba lebili le lebili le ka morao, joalo ka letoto le tloaelehileng la Wu ling le letoto la Song hua jiang.
