Tsav axles ntawm MAZ tsheb thauj khoom

Lub tsheb MAZ tuaj yeem muaj ob lub qag tsav (rov qab thiab qag ncej nrog lub qag los ntawm lub qag) lossis tsuas yog ib qho - rear. Tus tsim ntawm tus tsav qag muaj xws li lub hauv paus bevel iav txuas nrog lub planetary iav hauv lub log hubs. Choj kab teeb muaj ib qho kev sib txawv thiab muaj ob lub stamped halves txuas nrog vuam.

 

Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub qag tsav

Daim duab kinematic ntawm tus tsav qag yog raws li nram no: lub torque nkag mus rau hauv nruab nrab gearbox muab faib ua iav log. Meanwhile, nyob rau hauv lub log txo lub zog, sib txawv iav ratios yuav ua tau tiav los ntawm kev hloov tus naj npawb ntawm cov hniav ntawm lub log txo zog. Qhov no tso cai rau koj muab tib qhov loj me me rear qag rau ntau yam kev hloov kho ntawm MAZ.

Nyob ntawm qhov kev xav tau ntawm kev ua haujlwm ntawm MAZ qauv, kev hloov kho ntawm lub gearbox, qhov loj ntawm lub log tsheb ntawm lub tsheb, lub tsheb qag ntawm MAZ yog tsim los nrog peb qhov sib txawv tag nrho cov iav piv. Raws li rau nruab nrab qag MAZ, nws beam, tsav log thiab cross-axle txawv yog tsim los ntawm kev sib piv nrog rau qhov chaw ntawm lub rear qag. Nws yog ib qho yooj yim mus yuav los yog khaws cov khoom seem rau nruab nrab-ncej MAZ yog tias koj xa mus rau cov ntawv teev npe ntawm cov khoom qub qub.

Tsav qag tu

Thaum ua haujlwm ntawm lub tsheb MAZ, nws yuav tsum nco ntsoov tias cov axles tsav yuav tsum tau kho thiab hloov kho raws sijhawm. Thaum tsav tsheb txhua 50-000 km, nco ntsoov mus xyuas lub chaw pabcuam los tshuaj xyuas thiab, yog tias tsim nyog, kho qhov kev ua si axial ntawm cov kabmob ntawm cov tsav tsheb ntawm lub hauv paus gearbox. Nws yuav nyuaj rau cov neeg tsav tsheb uas tsis muaj kev paub los ua qhov kev hloov kho ntawm lawv tus kheej, vim. Ua ntej, tshem tawm lub kiv cua thiab ceev lub flange txiv ntoo rau qhov tsim nyog torque. Ib yam li ntawd, kev hloov ntawm lub gearbox ntawm lub hauv paus axis yog nqa tawm. Ntxiv nrog rau kev kho qhov tshem tawm hauv cov kabmob, nws yog ib qho tseem ceeb uas yuav tsum tau hloov cov roj nplua nyeem raws sijhawm, tswj xyuas cov roj nplua nyeem uas yuav tsum tau ua, thiab saib xyuas lub suab ntawm cov ncej.

Troubleshooting tsav axles

Lub rear gearbox maz sawv cev rau qhov siab tshaj plaws load. Txawm tias muaj qhov nruab nrab tsav qag tsis txo nws. Kev ua haujlwm tsis zoo ntawm cov axis tsav, ua rau thiab cov txheej txheem ntawm kev kho yuav raug txiav txim siab ntxiv.

Fault: choj overheating

Yog vim li cas 1: Tsis muaj los yog, conversely, ntau roj nyob rau hauv lub crankcase. Nqa cov roj mus rau qhov qub ntim hauv lub crankcases ntawm lub gearbox (central thiab log).

Ua rau 2: Gears tsis kho kom raug. Yuav tsum tau kho iav.

Ua rau 3: Ntau dhau cov kabmob preload. Lub bearing nro yuav tsum tau kho.

yuam kev: nce choj suab nrov

Ua rau 1: Bevel iav kev koom tes ua tsis tiav. Yuav tsum tau kho.

Ua rau 2: Hnav los yog misaligned tapered bearings. Nws yog ib qho tsim nyog los xyuas, yog tias tsim nyog, kho qhov nruj, hloov cov bearings.

Ua rau 3: iav hnav, hniav pitting. Nws yog ib qho tsim nyog los hloov cov iav hnav thiab kho lawv cov meshing.

Kab laum: Nce tus choj suab nrov thaum lub kaum sab xis

Ua rau: Differential tsis ua hauj lwm. Nws yog ib qho tsim nyog rau disassemble, kho thiab kho qhov sib txawv.

Teeb meem: iav suab nrov

Ua rau 1: Cov roj tsis txaus hauv lub log txo cov iav. Ncuav roj rau hauv lub gearbox vaj tse mus rau qib kom raug.

Ua rau 2: Technical roj tsis haum rau cov iav ntim. Ua tib zoo ntxuav cov hubs thiab tsav qhov chaw, sau nrog cov roj uas tsim nyog.

Ua rau 3: Hnav iav, pinion shafts lossis bearings. Hloov cov khoom hnav.

Fault: Roj los ntawm cov ntsaws ruaj ruaj

Ua rau: Hnav cov ntsaws ruaj ruaj ( qog). Hloov cov ntsaws ruaj ruaj. Yog tias muaj roj los ntawm lub qhov hub ntws, hloov lub hub foob.

Ua raws li cov txheej txheem ntawm koj "hlau nees", thiab nws yuav ua tsaug rau qhov kev pabcuam ntev thiab txhim khu kev qha.
