Automotive cov cuab yeej yog tsuas yog nruab nrog standardized internal combustion engines (ICEs), tus tsim ntawm uas yog teem rau kev tso kawm nyob rau hauv lub engine compartment. Txawm li cas los xij, muaj kev xav tau ntawm cov khoom siv hluav taws xob zoo li no hauv cov khoom siv vaj tsev, los ntawm cov chaw tsim khoom ntawm snowplows, snowmobiles, thiab lwm yam. Tsis tas li ntawd, cov kev xav tau ntawm kev sib koom ua ke thiab kev ua haujlwm tsis zoo nyob rau hauv cov xwm txheej no txawv ntawm cov qauv tsheb. Hauv qhov no, tag nrho ntu ntawm lub hom phiaj dav dav tau tsim nrog kev tsim kho kom zoo, tab sis cov yam ntxwv sib txawv.

Txoj kev sib sau ua ke

Zoo li lwm hom kev sib xyaw ua ke hauv lub tshuab hluav taws xob, cov khoom siv hluav taws xob dav dav siv los tsim thiab hloov thermal zog rau hauv lub tshuab hluav taws xob. Los ntawm optimizing qhov notxheej txheem nyob rau hauv cov ntsiab lus technical thiab cov qauv, cov neeg tsim khoom muaj peev xwm muab cov khoom no rau ntau tus neeg siv khoom. Ntawm lawv yog cov tuam txhab ua vaj, kev tsim kho, kev, kev tu, kev caij nkoj thiab cov khoom siv ua kis las thiab tshuab. Piv txwv li, hauv ntu kev tsim kho, lub hom phiaj dav dav tuaj yeem siv los txhawb cov khoom siv compressor. Nyob rau tib lub sijhawm, chav tsev nws tus kheej tsis tas yuav tsum tau muab tso rau hauv kev tsim ntawm lub compressor. Kev sib txuas yog nqa tawm nyob rau hauv ib qho kev txiav txim cais, thiab lub cav combustion sab hauv ua haujlwm raws li lub tshuab hluav taws xob siv hluav taws xob uas siv los ntawm roj av lossis roj av. Cov chaw tsim khoom vaj tsev muaj feem ntau yuav siv cov cav me me hauv cov tshuab txiav nyom, lub tshuab ua liaj ua teb, cov chaw tso dej, cov tshuab ua dej, thiab lwm yam. Cov khoom loj tshaj plaws thiab muaj zog tshaj plaws ntawm hom no yog siv rau hauv cov nroj tsuag fais fab, cov cuab yeej tshwj xeeb thiab cov khoom siv daus.

Tsim lub hom phiaj dav dav

Lub hauv paus ntsiab lus ntawm kev ua haujlwm yog tib yam li cov qauv hauv kev sib xyaw ua ke. Raws li, cov cuab yeej muab cov txheej txheem zoo sib xws nrog ib pawg ntawm lub tog raj kheej, bearings, crank mechanism thiab ncej. Qhov sib txawv tsuas yog nyob rau hauv qhov ntev, kev teeb tsa ntawm kev teeb tsa ntawm qhov chaw thiab cov khoom siv ntxiv. Raws li rau qhov loj me, mus rau qhov ntau dua cov no yog cov units compact. Ntawm qhov tod tes, qhov kev ua kom zoo me me yog txiav txim siab los ntawm kev txwv ntawm cov txheej txheem kev ua haujlwm thiab kev ua haujlwm (qhov me me ntawm cov khoom siv lub hom phiaj), thiab ntawm qhov tod tes, los ntawm kev xav tau ib puag ncig (tshwj xeeb tshaj yog raukhoom vaj khoom tsev).

Raws li kev teeb tsa kev teeb tsa, lub hom phiaj dav dav dav dav ntau dua li cov qauv siv rau kev tsheb. Universality yog manifested nyob rau hauv qhov tseeb hais tias chav tsev ntawm ib daim ntawv zoo tshaj yuav haum ob peb pab pawg neeg ntawm lub hom phiaj cov cuab yeej los ntawm ntau yam segments ib zaug. Rau kev ua haujlwm ergonomic ntau dua thiab nthuav dav ntawm kev sib koom ua ke muaj peev xwm ntawm hom combustion engine, siv cov cuab yeej pabcuam. Cov no tuaj yeem yog thav duab platforms, cov khoom siv nrog tes, thav ntawv thiab cov khoom thauj khoom nrog lub chassis.

Ntau yam ntawm lub hom phiaj dav dav hauv combustion xyaw

Kev teeb tsa kev teeb tsa ntawm cov khoom siv ua haujlwm yog ib qho ntawm cov yam ntxwv tseem ceeb ntawm kev sib cais ntawm cov qauv. Yog li, raws li qhov chaw ntawm lub crankshaft, lub hom phiaj ntawm sab hauv combustion xyaw yog cais raws li hauv qab no:

• Nrog kab rov tav. Cov cuab yeej zoo li no feem ntau siv rau hauv kev tsim khoom siv. Piv txwv li, pab pawg no suav nrog cov tshuab hluav taws xob sab hauv uas muab kev ua haujlwm ntawm cov phaj vibrating, cutters thiab qee lub tshuab dej dav hlau.
• Nrog ntsug ncej. Qhov kev daws teeb meem zoo tshaj plaws rau cov khoom siv me me, uas feem ntau yog tswj los ntawm tus neeg teb xov tooj ntawm qhov hnyav. Lub hom phiaj dav dav ntsug cav muaj xws li cov khoom siv fais fab rau cov nyom mowers thiab vaj trimmers. Nyob rau hauv xws li kev tsim, cov hniav txiav yog tsau rau lub crankshaft yam tsis muaj nruab nrab mechanisms, uas tsuas yog ua rau nws muaj peev xwm txo qhov loj thiab hnyav ntawm cov khoom.

Tus tsim ntawm tus ncej nws tus kheej kuj txawv. Nws yuav yog tapered los yogcylindrical puab. Thawj qhov kev xaiv yog qhov zoo dua nyob rau hauv cov nqe lus ntawm kev tso kawm ergonomics, tab sis qhov thib ob yog qhov txawv ntawm nws txoj kev siv ntau yam hauv txoj cai.

Specifications

Feem ntau peb tab tom tham txog cov teeb pom kev me me, tab sis hauv ntu no muaj qhov sib txawv ntawm qhov ntsuas qhov ntsuas hauv kev ua haujlwm thiab kev ua haujlwm. Piv txwv li, muaj ib ntu nrov ntawm lub cav ntawm 8 mus rau 13 hp. Nrog. Cov chav no tsuas yog siv ntau dua hauv cov khoom vaj khoom tsev. Nyob rau hauv ib lub tog raj kheej ntim txog li 1 liter, lub hwj chim muaj peev xwm ncav cuag 25 litres. Nrog. Cov no yog cov tshuab cua txias diesel uas tuaj yeem siv rau hauv kev tsim kho thiab thauj khoom. Tib lub hom phiaj dav dav diesel cav nrog spindle ceev ntawm txog 1500 rpm yog zoo kis nyob rau hauv lub niche ntawm industrial thiab coj mus muag khoom. Cov chav nyob hauv tsev feem ntau yog nruab nrog lub siab zaus plaub-stroke units khiav ntawm roj av. Txawm li cas los xij, kev siv ntau lub hom phiaj dav dav sab hauv combustion xyaw, nyob ntawm kev siv cov peev txheej, yuav tsum sib tham nyias.

Kev siv roj av cav

Ib pawg loj ntawm cov chaw tsim hluav taws xob uas pom lawv qhov chaw hauv tsev, kev lag luam thiab txawm tias lub zog. Piv txwv li, lub tshuab hluav taws xob roj tuaj yeem siv tau rau cov chaw tsim hluav taws xob uas muaj zog, ntawm qhov chaw siv hluav taws xob hauv chaw taws teeb ua lub zog thaub qab, lossis hauv lub zog ntawm lub tsev ntiag tug. Rau qhov nto moo tshaj plawsmanufacturers ntawm xws li internal combustion engine muaj xws li Robin-Subaru, Kipor, Green Field thiab Honda. Lawv kuj tsim cov txheej txheem tsav tsheb zoo rau kev taug kev-qab tsheb laij teb, snowmobiles, kev tsim kho thiab tshuab ua liaj ua teb. Ib tug neeg sawv cev ntawm ntu yog ib lub tog raj kheej dav dav-hom Honda engine nyob rau hauv lub CV 530 hloov. Qhov sib txawv tseem ceeb ntawm chav tsev no thiab diesel analogues tuaj yeem hu ua qib siab ntawm kev phooj ywg ib puag ncig.

Diesel cav daim ntawv thov

Diesel thev naus laus zis ib txwm yeej ntawm lub zog, uas tso cai rau nws los siv rau hauv kev teeb tsa kev tshaj lij thiab cov khoom siv nkoj. Nws kuj yog ib qho kev daws teeb meem zoo rau kev siv hluav taws xob tsis zoo, thiab, tsis zoo li cov roj av, xws li cov tshuab hluav taws xob sab hauv muaj lub neej ua haujlwm ntev dua nrog cov nqi saib xyuas zoo sib xws. Cov txheej txheem kev npaj ntawm lub hom phiaj dav dav diesel cav yog pom los ntawm German peb lub tog raj kheej Deutz TD226B-3D chav tsev, uas tseem suav hais tias yog ib qho ntawm kev lag luam tshaj plaws thiab ib puag ncig zoo hauv nws cov chav kawm. Cov yam ntxwv no tsuas yog ua tau vim muaj lub zog tag nrho tshem tawm (45-60 hp) los ntawm flywheel rau radial lossis axial tsav. Ntxiv rau qhov no yog dej txias nrog kev txhaj tshuaj ncaj qha.

Daim ntawv thov hluav taws xob

General-purpose electric motors kuj muaj lawv qhov zoo, uas yog qhia nyob rau hauv lawv cov phooj ywg ib puag ncig, tsis muaj suab nrovthiab qhov me me. Tau kawg, lawv kuj muaj qhov ntsuas qis tshaj plaws, tab sis qhov nuance no tsis tiv thaiv kev siv tag nrho cov txheej txheem no hauv maus taus, tib lub tshuab txiav nyom, hluav taws xob txiav thiab saw saws. Cov kev daws teeb meem tshiab hauv ntu ntawm lub hom phiaj dav dav tau ua kom pom tsis tu ncua los ntawm Siemens, tso cov qauv nrog lub zog ntawm 0.06 txog 1000 kW. Nyob rau hauv assortment ntawm lub tuam txhab koj yuav nrhiav tau txhuas thiab cam khwb cia hlau qauv uas haum rau ntau yam kev khiav hauj lwm tej yam kev mob.

Zaj lus

Lub tswv yim ntawm lub hom phiaj dav dav hauv lub tshuab hluav taws xob sab hauv yog tsav los ntawm kev xav tau kev ua haujlwm thev naus laus zis uas nthuav dav cov khoom siv hluav taws xob. Tawm tsam keeb kwm yav dhau los no, cov dej num ntawm kev sib koom ua ke ntawm cov cuab yeej siv no yog qhov ua tau zoo dua. Tab sis lub versatility ntawm lub cav muaj nws qhov tsis zoo sab. Lawv tau hais nyob rau hauv tus nqi siab, tsis tshua muaj zog thiab txij nkawm teeb meem. Ntawm qhov tod tes, Suav Lifan lub hom phiaj dav dav, rau tag nrho lawv qhov tsis txaus, uas tshwm sim nyob rau hauv cov ntsiab lus ntawm kev sib piv nrog tib German units, qhia ib tug piv txwv ntawm combining versatility thiab tsim nyog cov neeg siv khoom. Thiab qhov no tsis yog hais txog tus nqi qis ntawm cov khoom no, uas yog thawj zaug suav nrog hauv ntu nyiaj txiag. Lub hom phiaj tseem ceeb hauv kev sib xyaw ua ke hauv tsev los ntawm VTZ, YaMZ thiab Altai-diesel cov tuam txhab muaj npe nrov rau qee qhov zoo tib yam.
