Ntawm cov hoob kawm, yog tias koj tsis paub dab tsi yog txawv, ces koj tseem yuav tau tsav ib lub tsheb. Tab sis hais tias yog tag nrho tshaj thiab - nyob rau hauv ntau qhov koj yuav tsis tau, thiab nyob rau hauv qhov tseeb ntau tsav tsheb xav kom kho lawv tus kheej plaub-wheeled phooj ywg. Ntxiv mus, tus tsav tsheb muaj nws tus kheej tsis muaj sau zej zog, thiab koj yuav tsis yog nkag tau rau hauv, yog hais tias koj tsis muaj ib tug clue txog yuav ua li cas khiav lag luam yog koj lub tsheb. Qhov no yog vim li cas koj yuav tsum tau kawm kiag li tag nrho cov lus, raws li lawv tej zaum yuav zoo yuav pab tau rau koj nyob rau hauv lub neej yav tom ntej.

Thiab nyob rau hauv no tsab xov xwm yuav muab suav hais tias nyob rau hauv kom meej LSD-differential. Yuav ua li cas yog nws? Yuav ua li cas yog nws ua hauj lwm? Yuav ua li cas yog nws views yog? Tag nrho cov lus nug uas koj yuav nrhiav tau cov lus teb nyob rau hauv tus txheej txheem ntawm kev nyeem ntawv lub tsab xov xwm txog LSD-differential. Yuav ua li cas yog nws? Qhov no yog thawj lo lus nug hais tias kuv yuav nrhiav kom tau cov lus teb, tab sis tsis txhob maj. Ua ntej ntawm tag nrho cov koj yuav tsum paub hais tias xws li ib tug txawv nyob rau hauv tus, yog tias koj tsis paub. Yog hais tias cov ntaub ntawv koj twb paub, koj muaj peev xwm tsuas ua tshiab koj paub ua ntej cov tswv yim mus rau lub ntsiab yog ib feem ntawm tsab xov xwm.

Yuav ua li cas yog lub differential?

Yog li, lub ntsiab tseem ceeb ntawm cov khoom no - LSD-differential: nws yog dab tsi, yuav ua li cas nws ua hauj lwm, thiab li ntawm. Tiam sis ua ntej, koj yuav tsum tseem paub tias nyob rau hauv kev yog ib tug txawv. Muaj ntau tsav tsheb twb paub lub ntsiab txhais ntawm cov tswvyim no, tab sis yog tias koj ua nws yog tseem tsis paub hais tias, cov ntaub ntawv no yuav tseem ceeb heev rau koj kawm ntxiv txog lub npe.

Lub differential nyob rau hauv lub tsheb terminology - yog lub mechanism uas ntaub ntawv ib feem ntawm cov kis tau tus mob. Nws yog siv mus rau kis lub hwj chim, tiam sis nws muaj ib tug zoo feature, vim hais tias ntawm cov uas nws tau txais lub npe. Lub fact tias lub hwj chim nyob rau hauv lub differential kev sib hloov ntawm tus txheej txheem yog muab faib ua ob los yog differentially txuam kwj los yog ob tug hwj chim txaus yog summed rau hauv ib tug. Nws yog ib nqi sau cia hais tias lub ob ntws ntawm lub hwj chim txuas nws differentially, piv txwv li nyob rau hauv tus nqi lawv muab ib puas feem pua muaj peev xwm, tab sis nyob rau tib lub sij hawm lawv tsis muaj ib qho daim duab. Nyob rau hauv lwm yam lus, lawv yuav tsum tau muab raws li 50 mus rau 50 feem pua ntawm cov muaj peev xwm, thiab 70 mus rau 30 feem pua thiab 100 feem pua mus rau 0 thiab, conversely, 0 100 feem pua ntawm cov muaj peev xwm.

Zoo, qhov no yog qhov yooj yim ntaub ntawv hais txog cov differential nws tus kheej. Txawm li cas los, qhov kev kawm ntawm tsab xov xwm yog ib tug me ntsis txawv, yog li ntawd koj yuav tsum npaj mus rau lub saib xyuas ntawm cov khoom no. Subject ntawm tsab xov xwm - LSD-txawv, nws yog dab tsi, yuav ua li cas no mechanism thiab dab tsi yog nws views. Qhov no yog dab tsi yuav tsum tau tham ntxiv.

tsawg-plam txawv

Limited plam txawv LSD yog nws tus kheej-locking, thiab nws txawv ntawm lub classical impressively embodiment. Yuav ua li cas yog qhov txawv? Qhov tseeb hais tias lub xauv yog tshuab txais thaum ib tug loj sib txawv nyob rau hauv qag Ncej muab ceev, uas tso cai rau kom daws tau qhov teeb meem sai sai thiab nraaj. Qhov yooj yim piv txwv - nws buksovka pem hauv ntej los yog nram qab lub log, nws yog nws leej twg yog tus thawj ua ntawm qhov yuav tsum tau rau cov kev hloov nyob rau hauv lub classical differential. Thaum ib yam ntawm cov axles pib scrolling vim lub fact tias lub log yuav kov tsis yeej ib tug los yog lwm seem ntawm txoj kev, ib tug tsawg-plam txawv yuav ua tau ib tug tiag tiag txoj kev cawm seej.

Lawm, txawm thiab du txoj kev chaw thiab koj tsis xav tau ib tug xauv - tab sis qhov no yog vim li cas lwm rau koj los them ntau xim rau kev tshawb xav. Tom qab differentials muaj nyob nrog sib txawv xauv hom uas yog haum rau txawv tsav tsheb thiab kev sib txawv txoj kev chaw thiab tej yam kev mob. Uas yog vim li cas ntau xim rau koj thiab yuav tsum tau kawm, uas yog ib tug txawv ntawm lub tsa kev sib txhuam LSD.

tsiaj ntawv

Koj muaj ib tug tswv yim ntawm dab tsi yog qhov LSD tsawg plam txawv, txawm li cas los, yog hais tias lawv nug koj dab tsi no peb cov tsiaj ntawv, uas yog teev nyob rau hauv lub npe - koj yuav tsum tau teb? Nyob rau hauv qhov tseeb, txhua yam yog yooj yim heev - stands rau cov acronym raws li ib tug Limited plam txawv, uas yuav tsum tau txhais nyob rau hauv ntau txoj kev.

Ib tug xaiv tau lawm teev saum toj no - plam txawv, tab sis koj muaj peev xwm feem ntau nrhiav tau lwm - differential nrog nce hauv kuj. Ob leeg xaiv muaj tseeb, thiab yog hais tias koj siv ib yam ntawm lawv, koj yuav to taub. Tab sis nws yog ntau npaum li cas yooj yim, ntawm chav kawm, kom txhob muaj cov LSD siv, vim hais tias nws yog universal, cos thiab to taub rau tag nrho cov.

Txawm li cas los, qhov no yog tag nrho xwb theoretical cov ntaub ntawv - nws yog lub sij hawm mus nrog cov fact yuav ua li cas lub LSD-txawv, thiab pib sawv nrog nws sib piv nrog rau classical analogue.

Piv LSD differential ua hauj lwm nrog ib tug classic

Classical differential kuj muaj ntau lub npe, txhua tus uas yog siv heev lug. Nws yuav hu ua ib tug qauv, qhib thiab txawm dawb - thiab nws txawv feature yog lub fact tias nws tau tso cai tau ib tug sib txawv nyob rau hauv lub angular velocities ntawm cov zis shafts. Ua li cas nws txhais li cas? Qhov no txhais tau tias txhua tus ntawm cov zis shafts yuav ua raws li ib tug ib puas feem pua, thiab pes tsawg feem pua. Thiab qhov no, nyob rau hauv lem, txhais tau tias ib tug ntawm cov shafts yuav txawm nres. Nws yuav muab tau yooj yim pom nyob rau hauv cov tshuaj ntxuav thaum muaj ib tug log yog khiav ntawm tag nrho cov muaj peev xwm, thiab lub thib ob tsis scroll.

Yuav ua li cas yuav tiv nrog qhov teeb meem no LSD-differential? Lub hauv paus ntsiab lus ntawm cov lag luam ntawm no mechanism yog tsis tshua muaj tej yam yooj yim - nws muaj ib tug tsis siv neeg locking system uas tso cai rau qhov txawv ntawm ob tug hwj chim ntws, tab sis txaus me me, e.g., 60 feem pua mus rau 40 feem pua. Txawm li cas los, thaum qhov txawv tshaj qhov pub txwv, yog ib tug xauv uas tiv thaiv lub tsheb los ntawm qhov tsis zoo los ntawm qhov no tshwm sim. LSD-differential lag luam yog feem ntau tshwm nyob rau hauv lub off-txoj kev, raws li zoo raws li nyob rau hauv cov kev ua si tsheb.

Qhov twg siv xws li ib tug ntaus ntawv?

Raws li koj paub, rau txhua yam ntawm lub tsheb nws muaj nws tus kheej txoj kev ntawm txhav tas differentials thiab cov npoo muaj peev xwm. Yog hais tias koj tsav tsheb nyob rau hauv ib lub tsheb nyob rau hauv ib tug ca thiab tus leem txoj kev los yog txoj kev loj, koj tsis tas yuav saib xyuas txog qhov teeb meem piav saum toj no. Raws li hais ua ntej lawm, feem ntau siv yog xws li ib tug txawv nyob rau hauv off-txoj kev thiab cov kev ua si tsheb. Yog hais tias koj tsav ib tug SUV, ces feem ntau yuav, koj yuav tsum mus tshaj ntxhib struts, qhov twg nws yog yuav hais tias koj lub tsheb pib npleem. Thiab kom tsis txhob no, raws li koj twb to taub, koj xav tau ib tug zoo txawv xauv.

LSD-version yog hom phiaj haum rau qhov no, tusyees faib tus khiav ntawm lub hwj chim thiab tsis txhob hais tias ib tsob ntoo tau txais tag nrho lub hwj chim, thiab lwm yam tseem nyob ruaj ruaj. Roughly tib yam tshwm sim nyob rau hauv lub rooj plaub thaum koj tsav tsheb ib tug kev ua si tsheb. Txawm li cas los, nyob rau hauv cov ntaub ntawv no, koj lub hom phiaj tsis yog mus nrog ntxhib struts thiab kov yeej lub asphalt thaum pib.

Yog hais tias koj muaj tsawg kawg yog ib zaug pom raws li tus neeg nrog caij tsheb yuav pib thaum muaj kev kub ceev los ntawm ib qho chaw, koj twv yuav raug hu pom tias cov log yog scrolled thaum pib - qhov no yog cia li vim siab dhau heev lawm ib tug txawv nyob rau hauv lub hwj chim txaus. Limited-plam txawv thiaj no sib txawv rau ib tug siv tau yam tsawg kawg nkaus, li no nrhiav thiab scroll log pib thaum muaj kev kub ceev. Yog li ntawd, piv txwv li, LSD-differential Subaru sib xeem khiav qauv yuav siv zog kom tsis txhob tus siab kawg qhov sib txawv ntawm lub hwj chim tsev, tab sis tsis muaj prejudice rau tag nrho cov tsheb ua tau zoo.

hauv paus ntsiab lus ntawm cov lag luam

Koj twb muaj kev tswj kom tau ib tug dav dav lub tswv yim ntawm yuav ua li cas nws ua hauj lwm zoo ib yam li cov differential, tab sis muaj nqis saib nyias ntawm lub sij hawm no. Tom qab tag nrho, lub hauv paus ntsiab lus ntawm kev ua hauj lwm - qhov no yog dab tsi yog qhov tseem ceeb tshaj plaws taw tes nyob rau hauv tag nrho cov kev nkag siab ntawm lub ntaus ntawv. Yog li, qhov no mechanism chiv ua hauj lwm nyob rau hauv tib txoj kev raws li cov classical, - lub hwj chim yog nkag los ntawm ob raws, tab sis nyob rau hauv cov ntaub ntawv no muaj ib tug serial txwv qhov txawv ntawm cov ob powers, uas yuav ua tau tiav nyob rau hauv tus txheej txheem ntawm lub zog.

Raws li ib tug tshwm sim, thaum cov ntaub ntawv ntawm ib tug thaum muaj xwm ceev thiab lub hwj chim ntawm lub flow pib tshaj lub peev xwm ntawm lwm tus, tej hauj lwm hais tias tib xauv. Cov no ib tug redistribution ntawm lub hwj chim, tab sis, theej pib dua rau nws cov txheej txheem tis, uas yog, 50 mus rau 50 feem pua. torque normalization tso cai rau koj kom tau tawm ntawm ib tug yooj yim teeb meem no. Nyob rau hauv niaj hnub qauv ntawm differential xauv tseem active li ntev raws li qhov teeb meem no yog rov qab mus rau qub, uas yog, kom txog thaum lub sib cuag nrog rau txoj kev yuav tsis tau qoos rov qab los.

Hom LSD-differential

Raws li tau ua ntshiab heev, cov mechanisms yog tsis tus tsuas yog lub tsheb nyob rau hauv lub ntiaj teb no. Txawm li cas los, lawv lawv tus kheej yog tseem muab faib ua hom, uas koj yuav tsum tau muab nyob rau hauv ntau yam. Yog li ntawd, lub ntsiab hom muaj tsuas yog ob tug, tab sis lawv ua hauj lwm sib txawv kiag li tej ntsiab cai. Thawj yog ib tug qauv uas yog raws li nyob rau hauv qhov sib txawv ntawm rhiab heev rau tshaj tawm, thaum lub sij hawm thib ob - nyob rau rhiab heev rau qhov sib txawv nyob rau hauv cov kis torque. Txawm li cas los, yog li ntawd, yog yeej loj sib txawv rau them kev saib xyuas rau qhov no? Nws yog lub sij hawm mus kawm txog nws.

Qhov txawv ntawm cov LSD-differentials

Yog li ntawd, yog tias cov kev xaiv yog nruab nrab ntawm ob mechanisms, yog ib tus uas activates lub xauv, nyob ntawm seb qhov sib txawv nyob rau hauv ceev, thiab lwm yam - nyob ntawm seb qhov sib txawv nyob rau hauv torque, uas ib tug yuav tsum tau koj xaiv?

Nws yog ib nqi paub tias tus thawj hom ntau npaum li cas nrov, nws yog siv nyob rau hauv feem ntau lub tsheb uas yog khiav LSD-differential. Yog li ntawd, nws yog tsim nyog los ua ib tug xaiv nyob rau hauv dej siab ntawm nws. Yog vim li cas muaj raws li muaj ntau yam raws li ob tug. Tus thawj yog hais tias lub differential ua hauj lwm ua tsaug rau tus tsim raws li nyob rau hauv lub khov coupling - ib tug yooj yim haum mechanism uas yog ib qho yooj yim thiab pheej yig rau tsim. Yog li ntawd, tus nqi ntawm xws li ib tug txawv yuav qis, thaum tus neeg kho tshuab xauv ntawm lub thib ob hom yog kim kim los tsim thiab thiaj li kim kim thaum muas.

Qhov thib ob yog vim li cas cov lus dag nyob rau hauv lub simplicity thiab unpretentiousness viskomufty - koj tsis tau saib xyuas ntawm nws, thiab yog hais tias nws ib yam dab tsi tshwm sim, ces tus kho yuav yooj yim thiab pheej yig. Yog hais tias peb xav txog ob hom ntawm txawv, cov qauv siv muaj yog ib tug ncaj complex, muaj ib tug loj tus naj npawb ntawm qhov chaw, yog li ntawd lub kho LSD-differential yuav tsis yooj yim thiab kim.

Differentials uas yog nkag rau cov kev ceev sib txawv

Tam sim no nws yog lub sij hawm mus xyuas zoo dua no ob hom, raws li lawv kuj muaj cov distributions - raws li koj tau pom, qhov no qhov teeb meem yog tsis ua raws li tej yam yooj yim raws li nws yuav zoo li chiv.

Yog li ntawd, cov thawj version ntawm lub mechanisms raws li rhiab heev rau cov kev ceev sib txawv - yog ib tug khov differential. Koj yuav tsum ua tib zoo xaiv cov roj rau no hom ntawm LSD-txawv, vim hais tias no qhov tseem ceeb luag hauj lwm ua si los ntawm cov silicone gel, uas yuav tsum tsis txhob yuav tov nrog roj. Nws kuj khov coupling, uas yog lub ntsiab reservoir ntawm lub ntaus ntawv yog kev sib khi.

Nyob rau hauv qhov tseeb, precisely vim hais tias ntawm lub gel thiab tau ib tug ntawm cov loj zoo ntawm no hom ntawm differential - lawv ua hauj lwm heev ntseeg nkaws vim cov kev hloov nyob rau hauv lub zog ntawm cov gel. Ua tsaug rau nws, disappears aliasing, uas yog ib qho teeb meem nyob rau hauv ntau transmissions. Thiab muab qhov tseeb hais tias lub automotive kev lag luam yog tam sim no mas tswj kev txhim kho txoj kev nplij siab tus neeg tsav tsheb thiab cov neeg caij tsheb, cov cuab yeej no tau qho tseem ceeb heev.

Tab sis tsis txhob xav tias hais tias qhov no hom ntawm differential yog zoo meej - nws muaj nws cov drawbacks. Piv txwv li, cov hauj lwm no yog accomplished los ntawm cov kua siab, uas yog ib feem ntawm lub zog yog poob, thiab yog li ntawd tsub kom roj noj. Tsis tas li ntawd tsis txhob hnov qab hais tias xws li ib tug mechanism yog rhiab heev rau siab loads, yog li ntawd nrog txhua muaj zog towing nws cov hauj lwm zoo yuav txo tau. Thiab, ntawm chav kawm, rau qhov LSD-differential roj, uas twb tau sib tham txog twb saum toj no, yuav tsum tau ntawm siab zoo, txij li thaum lub khov coupling muaj ib tug muaj zog rhiab heev rau compaction.

Txawm li cas los, muaj lwm yam ntawm differential rhiab ceev sib txawv - lawv khiav lag luam rau lub hauv paus ntawm gertornogo twj tso kua mis. Qhov no yog ib tug kuj tsis ntev los no technology - ntau yeej, nws pib tau txais txoj kev loj hlob ua ke nrog computer kho, raws li gertornym twj tso kua mis neeg tsav tsheb yuav khiav lag luam ntawm nws tus kheej nyob rau hauv niaj hnub tsheb. Hais tias nyob rau hauv lub nyob ze yav tom ntej yuav tsum raws nraim li no yuav tsum yog tus nrov tshaj plaws - nws yog teem, piv txwv li, nyob rau tag nrho cov tsheb Toyota. Tab sis tsis txhob hnov qab tias koj tam sim no yuav tsum ua tib zoo xaiv cov roj rau LSD. Txawv Toyota thiab lwm hom uas siv cov technology no yog rhiab rau nws.

Differentials uas yog nkag mus rau lub qhov sib txawv nyob rau hauv cov kis ntawm torque

Zoo, thiab lub thib ob hom, raws li koj paub, yog tsis nkag siab cov kev ceev sib txawv, thiab cov kis ntawm torque. Lawm, tsim cov ntawm no mechanism yog heev txawv - feem ntau nyob rau hauv cov kev ua lag luam raws li tus neeg kho tshuab differentials cab hom. Lawv ua hauj lwm yog los xyuas kom meej tias cov tsis siv neeg locking nyob rau hauv cov kev tshwm sim hais tias qhov txawv ntawm torques nyob rau hauv lub vaj tse nyob thiab cov tsav ncej tshaj lub permissible cai. Raws li ib tug tshwm sim, yog qhov txawv yog ntau zog rau tsis tsim nyog kev ua tau zoo, ces muaj yog ib tug tsis siv redistribution ntawm torque.

Nws yog ib nqi hmoog rau lub fact tias lub xauv yog tsis tiav, uas yog, nws yog nyob ntawm raws nraim li cas yog qhov txawv ntawm lub cev thiab lub torque ntawm tus tsav ncej. Feem ntau qhov no yog lub rear differential LSD - uas txhais tau tias nws yog tsis tsim nyob rau hauv pem hauv ntej thiab nyob rau lub rear qag ntawm lub tsheb.

Koj yuav nrhiav tau ob tug ntawm cov feem ntau nrov sub-hom ntawm no mechanism - thiab kvayf Thorsen. Keeb kwm tsim ncaj qha los ntawm ob English lus, torque thiab sensing, uas translates li "torque" thiab "rhiab", ntsig txog.

Zoo, tam sim no koj paub yuav luag txhua yam uas koj yuav tsum paub txog xws li ib tug mechanism li LSD differential. Toyota, BMW, Mercedes thiab tag nrho cov leading hom ntawm lub tsheb hnub no yog yuav luag ib txwm nruab nrog xws li yog vim hais tias thaum lub sij hawm ntawd lawv yog feem ntau zoo.
