Nyob rau hauv kev sib kis ntawm KAMAZ tsheb thauj khoom, interaxle thiab cross-axle sib txawv yog muab, nyob rau hauv uas lub hauv paus chaw yog nyob rau hauv crosses.Kawm paub tias tus ntoo khaub lig yog dab tsi, hom twg nws yog, nws ua haujlwm li cas thiab nws ua haujlwm li cas, nrog rau kev xaiv thiab hloov ntawm cov khoom no los ntawm kab lus.
Dab tsi yog qhov sib txawv ntawm KAMAZ?
Tus ntoo khaub lig ntawm KAMAZ qhov sib txawv yog ib feem ntawm qhov chaw nruab nrab thiab qhov sib txawv ntawm qhov sib txawv ntawm cov tsav axles ntawm KAMAZ tsheb;Ib feem cruciform uas ua raws li axes rau satellite iav.
Tus ntoo khaub lig yog ib qho tseem ceeb ntawm txhua hom kev sib txawv - ob qho tib si cross-axle, nyob rau hauv lub gearboxes ntawm tag nrho cov tsav axles, thiab inter-axle, mounted ntawm ib nrab qag.Qhov no muaj ntau yam haujlwm:
● Ua raws li cov axles rau kev sib txawv satellites - lub zog yog mounted rau ntawm lub spikes ntawm tus ntoo khaub lig thiab tig ywj siab rau nws;
● Centering ntawm mating qhov chaw ntawm qhov sib txawv - satellites thiab lub zog ntawm lub qag shafts;
● Kev xa tawm ntawm torque los ntawm qhov sib txawv vaj tse mus rau lub satellites thiab ntxiv mus rau lub zog ntawm lub qag shafts (nyob rau hauv qee hom ntawm cov units, lub torque yog kis ncaj qha los ntawm crosspiece);
● Uniform faib ntawm lub load ntawm lub zog ntawm lub qag shafts - qhov no txo cov load ntawm tag nrho cov zog, ua rau lawv cov kev pab cuam lub neej thiab kev cia siab ntawm lub torque tseem ceeb;
● Lubricant muab rau cov bushings (dawb bearings) ntawm satellites.
Qhov xwm txheej ntawm tus ntoo khaub lig feem ntau yog nyob ntawm kev ua haujlwm ntawm qhov sib txawv, kev ua haujlwm ntawm kev sib kis torque thiab kev ntseeg tau.Tus ntoo khaub lig faulty yuav tsum tau kho lossis hloov, tab sis ua ntej yuav qhov tshiab, koj yuav tsum nkag siab txog hom KAMAZ crosses, lawv cov yam ntxwv thiab kev siv tau.
Hom, tsim thiab nta ntawm KAMAZ sib txawv crosses
Tag nrho KAMAZ crosses tau muab faib ua ob pawg loj raws li lawv qhov kev siv tau:
● Hla ntawm qhov sib txawv ntawm qhov sib txawv (tsav qag gearboxes);
● Hla ntawm qhov chaw sib txawv.
Crosses ntawm thawj hom yog siv nyob rau hauv qhov sib txawv ntawm gearboxes ntawm tag nrho cov tsav axles - pem hauv ntej, nruab nrab (yog tias muaj) thiab rear.Ntawm no, qhov no ua kom muaj kev sib faib ntawm torque ntawm lub qag shafts ntawm qhov tsis sib xws ntawm kev sib hloov ntawm txoj cai thiab sab laug log.
Differential cross sib dhos nrog satellites
Hla ntawm hom thib ob yog qhov tseem ceeb ntawm qhov chaw sib txawv nruab nrab ntawm lub tsheb nruab nrab ntawm lub tsheb nrog lub log qauv 6 × 4 thiab 6 × 6, thiab kev xa ncaj qha ntawm lub zog mus rau nruab nrab thiab nram qab qag (tsis muaj rooj plaub hloov).Ntawm no, qhov no ua kom muaj kev sib faib ntawm torque ntawm nruab nrab thiab nram qab qag ntawm qhov tsis sib xws ntawm kev sib hloov ntawm lawv lub log.
Crosses ntawm ob hom muaj tib yam tsim nyob rau hauv txoj cai.Qhov no yog ib qho khoom siv uas muaj ob qhov sib txawv: lub nplhaib hauv nruab nrab (hub), nrog rau qhov ncig ntawm plaub qhov sib txawv ntawm qhov sib txawv.Lub qhov nyob rau hauv lub hub ua hauj lwm rau nruab nrab ntawm ib feem thiab pab txhawb nws, thiab nyob rau hauv qhov chaw sib txawv, lub rear qag tsav ncej dhau los ntawm nws.Satellite iav thiab kev txhawb nqa lub tshuab ntxhua khaub ncaws tau nruab rau ntawm qhov sib txawv los ntawm cov bushings, tiv thaiv kev sib cuag ncaj qha ntawm satellites nrog cov cav tov ntawm lub khob vaj huam sib luag.
Cov spikes muaj qhov sib txawv ntawm qhov sib txawv: ntawm ob sab uas tig mus rau qhov nruab nrab ntawm crosspiece, cov balds raug tshem tawm nyob rau tib theem nrog lub dav hlau ntawm lub hub ntawm tus ntoo khaub lig.Lysks xyuas kom cov roj ntws mus rau cov bushings ntawm satellites thiab tshem tawm cov khoom coj los ntawm lawv.Qhov muag tsis pom qhov tob ntawm qhov tob feem ntau yog drilled ntawm qhov kawg ntawm cov spikes, uas pab txhawb kev ua haujlwm ntawm ib feem.Tsis tas li ntawd, chamfers raug tshem tawm ntawm qhov kawg kom yooj yim dua installation ntawm tus ntoo khaub lig nyob rau hauv qhov sib txawv vaj tse.Txoj kab uas hla ntawm cov studs ntawm crosses ntawm tus ntoo khaub lig-axle sib txawv ntawm KAMAZ yog 28.0-28.11 hli, txoj kab uas hla ntawm studs ntawm crosses ntawm qhov chaw sib txawv nyob rau hauv qhov ntau ntawm 21.8-21.96 hli.
Tag nrho cov ntoo khaub lig yog ua los ntawm cov qauv hlau ntawm qib 15X, 18X, 20X thiab lwm yam los ntawm kub stamping (forging) ua raws li kev tig, qhov saum npoo ntawm cov studs ntawm cov khoom tiav yog raug rau kev kho cua sov (carburizing mus rau qhov tob ntawm 1.2 hli, quenching thiab tom qab tempering) kom ua tiav qhov xav tau hardness thiab tsis kam rau abrasive hnav.
Muaj ob hom kev hla ntawm qhov chaw sib txawv ntawm KAMAZ tsheb:
● Nrog lub qhov nruab nrab du;
● Nrog slotted hub.
Qhov chaw ntawm thawj hom muaj cov qauv tsim tau piav qhia saum toj no, lawv tau siv nyob rau hauv qhov chaw sib txawv, ua raws li cov txheej txheem classical - nrog rau kev hloov ntawm lub zog ntawm lub kiv cua mus rau qhov sib txawv vaj tse, uas tus ntoo khaub lig yog rigidly txuas.Qhov thib ob hom muaj ib lub hub ntawm nce dav, nyob rau hauv lub puab ib feem ntawm longitudinal splines yog ua.Cov ntoo khaub lig no yog siv nyob rau hauv qhov chaw sib txawv ntawm ib hom tshiab (ntsia rau KAMAZ-6520 cov tsheb thauj khoom thiab kev hloov kho raws li lawv txij li xyoo 2009) - nrog rau kev hloov ntawm lub zog ntawm lub kiv cua ncaj qha mus rau crosspiece.Qhov sib txawv ntawm hom no yog ntau compact thiab yooj yim dua, tab sis nyob rau hauv lawv tus ntoo khaub lig yog raug mus rau ntau dua loads, yog li yuav tsum nruj me ntsis rau lawv tsim thiab zoo.

Kev ua haujlwm ntawm D-pads hauv qhov sib txawv yog qhov yooj yim heev.Hauv kev sib txawv ntawm qhov sib txawv, nws tsuas yog ua raws li axles rau satellites.Tus ntoo khaub lig yog rigidly mounted ntawm qhov sib txawv vaj tse lub tais, uas, nyob rau hauv lem, yog ntsia nyob rau hauv lub tsav iav ntawm lub ntsiab iav.Thaum lub iav tig, qhov sib txawv tig tib lub sijhawm, cov satellites txuas nrog tus ntoo khaub lig, koom nrog lub zog ntawm lub qag shafts, coj lawv mus rau hauv kev sib hloov, kom ntseeg tau tias kev sib kis ntawm torque mus rau lub log tsav.Thaum lub kaum sab xis los yog tsav tsheb ntawm txoj kev ntub dej, cov satellites tig rau ntawm qhov sib txawv ntawm qhov crosspiece, muab cov log sib txawv.
Hauv nruab nrab qhov sib txawv, cov ntoo khaub lig ua haujlwm zoo sib xws, tab sis nrog lawv cov kev pab cuam lub torque raug faib nruab nrab ntawm cov tsav axles.
Cov teeb meem ntawm kev xaiv thiab hloov cov ntoo khaub lig ntawm KAMAZ sib txawv
Cov crosses sib txawv yog raug rau cov loads siab thaum lub sijhawm ua haujlwm ntawm lub tsheb, yog li thaum lub sijhawm lawv hnav thiab deform.Qhov xwm txheej ntawm qhov no yog saib xyuas thaum lub sij hawm tu lub sij hawm los yog thaum lub sij hawm kho ntawm tus tsav qag.Yog tias cov chips, scuffs, tawg thiab lwm yam kev puas tsuaj pom nyob rau ntawm crosspiece, ces nws yuav tsum tau hloov.Yog hais tias lub spikes ntawm tus ntoo khaub lig muaj ib tug abrasive hnav nrog ib tug txo nyob rau hauv txoj kab uas hla, ces lawv yuav rov qab los ntawm hlau surfacing thiab sib tsoo, tab sis hnub no nws yog ntau yooj yim dua thiab pheej yig dua mus yuav ib tug tshiab ntoo khaub lig.Yog tias kuaj pom muaj teeb meem hauv satellites thiab cov ntxhua khaub ncaws (chips, cov hniav tsis sib xws, tawg thiab tawg hauv cov hniav, thiab lwm yam), ces lawv yuav tsum tau hloov ua ke nrog cov hlaws dai, thiab ua tiav cov txheej txheem (nrog bushings thiab thrust washers).
