Tsav qag yog tsim los ntawm lub ntsiab reducer, sib txawv, ib nrab ncej thiab tsav qag vaj tsev.
Main Decelerator
Lub ntsiab reducer feem ntau yog siv los hloov cov kev taw qhia kis tau tus mob, txo qhov ceev, ua kom lub zog torque, thiab xyuas kom meej tias lub tsheb muaj zog tsav txaus thiab tsim nyog ceev. Muaj ntau ntau yam ntawm lub ntsiab reducers, xws li ib-theem, ob-theem, ob-ceev, thiab log-sab reducers.
1) Ib-theem lub ntsiab reducer
Ib qho cuab yeej uas paub txog kev txo qis los ntawm ob lub zog txo qis yog hu ua ib-theem reducer. Nws yog qhov yooj yim hauv cov qauv thiab lub teeb hauv qhov hnyav, thiab tau siv dav hauv lub teeb thiab nruab nrab cov tsheb thauj khoom xws li Dongfeng BQl090.
2) Ob-theem lub ntsiab reducer
Rau qee lub tsheb thauj khoom hnyav, yuav tsum muaj qhov txo qis loj, thiab ib-theem lub ntsiab reducer yog siv rau kev sib kis, thiab txoj kab uas hla ntawm lub iav tsav yuav tsum tau nce ntxiv, uas yuav cuam tshuam rau hauv av clearance ntawm tsav qag, yog li ob kev txo qis yog siv. Feem ntau hu ua ob-theem reducer. Ob-theem reducer muaj ob txheej ntawm kev txo qis zog, uas paub txog ob qhov kev txo qis thiab qhov nce ntxiv.
Txhawm rau txhim kho lub meshing stability thiab lub zog ntawm lub bevel iav khub, thawj theem txo cov iav khub yog ib tug kauv bevel iav. Qhov thib ob iav khub yog helical cylindrical iav.
Kev tsav tsheb bevel iav tig, uas ua rau cov tsav bevel iav tig, yog li ua tiav thawj theem ntawm deceleration. Tus tsav tsheb cylindrical iav ntawm lub thib ob-theem deceleration rotates coaxially nrog cov tsav bevel iav, thiab tsav cov tsav cylindrical iav tig mus nqa tawm lub thib ob-theem deceleration. Vim hais tias tus tsav spur iav yog mounted rau ntawm qhov sib txawv vaj tse, thaum tsav spur iav rotates, lub log yog tsav los tig los ntawm qhov sib txawv thiab ib nrab ncej.
Sib txawv
Qhov sib txawv yog siv los txuas rau sab laug thiab sab xis ib nrab shafts, uas tuaj yeem ua rau lub log ntawm ob sab tig ntawm qhov sib txawv angular speeds thiab xa torque tib lub sijhawm. Xyuas kom qhov qub dov ntawm lub log. Qee lub tsheb ntau lub qag-tsav kuj tseem muaj qhov sib txawv hauv cov ntaub ntawv hloov chaw lossis nruab nrab ntawm cov ncej ntawm kev tsav tsheb, uas yog hu ua inter-axle differentials. Nws txoj haujlwm yog los tsim kom muaj qhov sib txawv ntawm lub log pem hauv ntej thiab nraub qaum thaum lub tsheb tig los yog tsav tsheb ntawm txoj kev tsis sib xws.
Hauv tsev sedans thiab lwm hom tsheb yeej siv symmetrical bevel iav zoo tib yam sib txawv. Lub symmetrical bevel iav sib txawv muaj xws li planetary iav, sab iav, planetary iav shafts (cross shafts los yog ib tug ncaj pin ncej) thiab txawv vaj tse.
Cov tsheb feem ntau siv cov iav planetary sib txawv, thiab cov iav bevel zoo tib yam muaj ob lossis plaub lub conical planetary iav, planetary iav shafts, ob lub conical sab iav, thiab sab laug thiab txoj cai sib txawv vaj tse.
Ib nrab Ncej
Ib nrab ncej yog ib qho khoom siv uas xa cov torque los ntawm qhov sib txawv mus rau lub log, tsav lub log kom tig thiab txav lub tsheb. Vim qhov sib txawv ntawm cov qauv ntawm lub hub, lub zog ntawm ib nrab ncej kuj txawv. Yog li ntawd, ib nrab ncej yog muab faib ua peb hom: tag nrho floating, semi floating thiab 3/4 floating.
1) Puv floating ib nrab ncej
Feem ntau, cov tsheb loj thiab nruab nrab siv tag nrho cov qauv ntab. Sab hauv kawg ntawm ib nrab ncej yog txuas nrog ib nrab ncej iav ntawm qhov sib txawv nrog splines, thiab sab nrauv kawg ntawm ib nrab ncej yog forged nrog flange thiab txuas nrog lub log hub los ntawm bolts. Lub hub tau txais kev txhawb nqa ntawm ib nrab lub tes tsho los ntawm ob lub tapered roller bearings uas nyob deb sib nrug. Lub axles bushing thiab lub rear qag vaj tse yog nias-haum rau hauv ib lub cev los tsim cov tsav qag vaj tse. Nrog rau hom kev txhawb nqa no, ib nrab ncej tsis txuas ncaj qha nrog lub qag vaj tse, yog li ntawd ib nrab ncej tsuas yog tuav lub zog tsav tsheb yam tsis muaj lub sijhawm khoov. Hom ib nrab ncej no hu ua "full floating" ib nrab ncej. Los ntawm "floating" nws txhais tau hais tias ib nrab shafts tsis raug khoov loads.
Puv-floating ib nrab ncej, sab nrauv kawg yog flange phaj thiab cov ncej yog kev sib xyaw. Tab sis kuj tseem muaj qee cov tsheb thauj khoom uas ua rau lub flange rau hauv ib qho kev sib cais thiab haum rau sab nraud ntawm ib nrab ntawm cov ncej los ntawm txoj kev splines. Yog li ntawd, ob qhov kawg ntawm ib nrab ncej yog splined, uas yuav siv tau nrog interchangeable hau.
2) Semi-floating ib nrab ncej
Sab hauv kawg ntawm lub semi-floating ib nrab-ncej yog tib yam li cov dej puv puv, thiab tsis dais dabtsis thiab torsion. Nws sab nraud yog ncaj qha txhawb rau sab hauv ntawm lub qag tsev nyob los ntawm ib tug bearing. Hom kev txhawb nqa no yuav tso cai rau sab nraud ntawm lub qag ncej kom dais lub sijhawm khoov. Yog li ntawd, lub tsho ib nrab no tsis tsuas yog xa cov torque xwb, tab sis kuj yog ib feem ntawm lub sijhawm khoov, yog li nws yog hu ua semi-floating semi-shaft. Hom qauv no feem ntau yog siv rau cov tsheb me me.
Daim duab qhia tau hais tias tsav qag ntawm Hongqi CA7560 khoom kim heev tsheb. Sab hauv kawg ntawm ib nrab ncej tsis raug rau lub sijhawm khoov, thaum lub sijhawm sab nrauv yuav tsum tau dais txhua lub sijhawm khoov, yog li nws yog hu ua semi-floating bearing.
3) 3/4 ntab ib nrab ncej
Lub 3/4 floating ib nrab ncej yog nruab nrab ntawm lub semi-floating thiab tag nrho ntab. Hom semi-axle no tsis yog siv dav, thiab tsuas yog siv rau hauv ib lub tsheb pw tsaug zog, xws li Warsaw M20 tsheb.
qag tsev
1. Integral qag vaj tse
Lub tog raj kheej kheej kheej yog siv dav vim nws lub zog zoo thiab kev nruj, uas yooj yim rau kev teeb tsa, kev hloov kho thiab kev saib xyuas ntawm lub ntsiab reducer. Vim muaj ntau txoj kev tsim khoom, cov vaj tse nyob hauv lub qag tuaj yeem muab faib ua ib hom kev sib tw, nruab nrab-section casting xovxwm-hauv steel raj hom, thiab steel phaj stamping thiab vuam hom.
2. Segmented tsav qag tsev nyob
Lub segmented qag vaj tsev feem ntau muab faib ua ob ntu, thiab ob ntu txuas nrog bolts. Segmented qag tsev nyob yog yooj yim rau cam khwb cia thiab tshuab.
