Ntchito ya chimbalangondo cholekanitsa magalimoto
Chotengera chotulutsira clutch chagalimoto (Automobile clutch release bearing) ndi gawo lofunika kwambiri pa makina otumizira magiya. Chimayikidwa pakati pa clutch ndi chotumizira magiya, ndipo kudzera mu kuzungulira kogwirizana ndi kayendedwe ka axial ka chotulutsira magiya, chimalola kuti clutch igwirizane bwino komanso ichotsedwe, kuchepetsa kuwonongeka ndikuwonjezera moyo wa makina otumizira magiya. Kapangidwe kake ndi kotayirira ndipo kamayikidwa pa chivundikiro chonyamula magiya choyamba, kudalira kasupe wobwerera kuti asunge mpata ndi kumapeto kwa chotulutsira magiya, kuonetsetsa kuti ntchito ikuyenda bwino.
Bearing iyi iyenera kukwaniritsa miyezo yaukadaulo ya axial clearance ya ≤ 0.60mm ndi kuvala kwamkati kwa raceway ya ≤ 0.30mm. Zolakwika nthawi zambiri zimaonekera ngati phokoso losazolowereka kapena kuyima, makamaka chifukwa cha mafuta osakwanira, ntchito zotulutsa pang'onopang'ono, kapena kusintha kosayenera kwa kuyenda kwaulere. Kusamalira kumafuna mafuta okhazikika ndi mafuta ochokera ku lithiamu, kusintha kusalala kwa lever yotulutsa, ndi kuwongolera kuyenda kwaulere mkati mwa 30-40mm. Mafotokozedwe oyenera angatanthauze "JB/T5312-2001 Automobile Clutch Release Bearing ndi Unit Yake".
Ngati chogwirira chotulutsa clutch sichikukwaniritsa zofunikira zomwe zili pamwambapa, chimaonedwa kuti ndi cholakwika. Zolakwika nthawi zambiri zimaonekera ngati phokoso losazolowereka kapena kuyima. Zomwe zimayambitsa kwambiri ndi mafuta osakwanira, ntchito zotulutsa pang'onopang'ono, kapena kusintha kosayenera kwa kuyenda kwaulere. Kukonza kuyenera kuchitika nthawi zonse pogwiritsa ntchito mafuta ochokera ku lithiamu popaka mafuta, kusintha kusalala kwa chogwirira chotulutsa, ndikuwongolera kuyenda kwaulere mkati mwa 30-40mm. Mafotokozedwe oyenera angatanthauze "JB/T5312-2001 Automobile Clutch Release Bearing ndi Unit Yake".
Ngati chogwirira chotulutsa clutch sichikukwaniritsa zofunikira zomwe zili pamwambapa, chimaonedwa kuti ndi cholakwika. Pambuyo poti vuto lachitika, gawo loyamba ndikudziwa chomwe chimayambitsa kuwonongeka kwa chogwirira chotulutsa clutch. Injini ikayamba, kanikizani pang'ono chogwirira clutch. Pamene ulendo waulere wangochotsedwa, phokoso la "kufuula" kapena "kudina" limachitika. Kupitiliza kukanikiza chogwirira clutch, ngati phokosolo latha, si vuto ndi chogwirira chotulutsa clutch. Ngati pali phokoso, chogwirira chotulutsa clutch ndi chomwe chili ndi vuto.
Pakuwunika, chivundikiro cha maziko a clutch chingachotsedwe, kenako kuponda pang'ono pa accelerator pedal, kuonjezera pang'ono liwiro la injini. Ngati phokoso likuwonjezeka, yang'anirani ngati pali ma spark. Ngati pali ma spark mu kuphulika, zimasonyeza kuti clutch release bearing yawonongeka. Ngati ma spark atuluka mosalekeza, zimasonyeza kuti mipira ya clutch release bearing yasweka. Ngati palibe ma spark koma phokoso lachitsulo likumveka, zimasonyeza kuwonongeka kwambiri.
Mikhalidwe yogwirira ntchito
Chotengera chotulutsa clutch
Pakagwiritsidwa ntchito, imayikidwa pa axial load, impact load, ndi radial centrifugal force pa liwiro lalikulu. Kuphatikiza apo, chifukwa cha kukankha kwa shift fork ndi reaction force ya release lever kusakhala pamzere wowongoka womwewo, torsional moment imapangidwanso. Mikhalidwe yogwirira ntchito ya clutch release bearing ndi yoipa, yokhala ndi kusinthasintha kwa liwiro komanso kuthamanga kwambiri, kutentha kwambiri, mafuta osakwanira, komanso kuzizira.
Zoyambitsa kuwonongeka
Kuwonongeka kwa clutch release bearing kumagwirizana kwambiri ndi momwe dalaivala amagwirira ntchito komanso momwe amasamalirira, komanso kusintha kwake. Zomwe zimayambitsa kuwonongeka ndi izi:
Kutentha kwambiri kuntchito kumabweretsa kutentha kwambiri
Madalaivala ambiri nthawi zambiri amayendetsa theka la clutch akamatembenuza kapena kuchedwetsa liwiro, ndipo ena amasuntha magiya ndipo amapitirizabe kuyenda pa clutch pedal; magalimoto ena amakhala ndi maulendo ambiri omasuka, zomwe zimapangitsa kuti clutch isatuluke kwathunthu ndipo imakhala mu mkhalidwe wosagwirizana pang'ono komanso wosagwirizana pang'ono. Mkhalidwe uwu umayambitsa kukangana kouma ndipo umapanga kutentha kwakukulu komwe kumasamutsira ku clutch release bearing, zomwe zimapangitsa kuti bearing ifike kutentha kwina, ndi mafuta kusungunuka kapena kuchepetsedwa ndi kuyenda, zomwe zimawonjezera kutentha kwa clutch release bearing. Kutentha kukafika pamlingo winawake, kumayaka.
Kusowa kwa mafuta odzola kumabweretsa kuwonongeka
Chogwirira chotulutsa clutch chimapaka mafuta. Pali njira ziwiri zowonjezera mafuta: pa chogwirira chotulutsa clutch cha 360111, chivundikiro chakumbuyo cha chogwirira chiyenera kutsegulidwa ndikudzazidwa mafuta panthawi yokonza kapena pamene cholumikizira chachotsedwa, kenako chivundikiro chakumbuyo chiyenera kukonzedwanso; pa chogwirira chotulutsa clutch cha 788611K, chikhoza kuchotsedwa ndikumizidwa mu mafuta osungunuka, kuzizira, kenako nkuchotsedwa kuti chikhale ndi mafuta. Pantchito yeniyeni, oyendetsa nthawi zambiri amanyalanyaza mfundo iyi, zomwe zimapangitsa kuti chogwirira chotulutsa clutch chisakhale ndi mafuta opaka. Popanda mafuta kapena mafuta osakwanira, kuwonongeka kwa chogwirira chotulutsa clutch nthawi zambiri kumakhala kochulukirapo kuposa momwe chimakhalira ndi mafuta. Kuwonjezeka kwa kuwonongeka kudzapangitsanso kutentha kwakukulu, zomwe zimapangitsa kuti chiwonongeke mosavuta.
Ulendo waulere ndi wochepa kwambiri kapena nthawi yodzaza katundu wambiri
Malinga ndi zofunikira, kusiyana kwa 2.5mm pakati pa chopatulira cholekanitsa cha clutch ndi chopatulira cholekanitsa kumaonedwa kuti ndi koyenera kwambiri. Izi zikugwirizana ndi kuyenda kwaulere kwa 30-40mm pa chopatulira cholekanitsa. Ngati kuyenda kwaulere kuli kochepa kwambiri kapena palibe kuyenda kwaulere konse, chopatulira cholekanitsa ndi chopatulira cholekanitsa zidzakhalabe mu mkhalidwe wokhazikika. Malinga ndi mfundo ya kutopa, nthawi yayitali yogwirira ntchito ya chopatulira, kuwonongeka kudzakhala kwakukulu kwambiri; nthawi zambiri ikakwezedwa, chopatulira cholekanitsa chimakhala chosavuta kuvutika ndi kutopa. Kuphatikiza apo, nthawi yayitali yogwirira ntchito, kutentha kwa chopatulira kumakhala kwakukulu, zomwe zimapangitsa kuti chizime mosavuta, motero kuchepetsa nthawi yogwira ntchito ya chopatulira cholekanitsa.
Kuwonjezera pa zifukwa zitatu izi, kaya kusintha kwa lever yolekanitsa kuli kosalala, komanso ngati kasupe wobwerera wa bearing yolekanitsa ili bwino, zimakhudzanso kwambiri kuwonongeka kwa bearing yolekanitsa.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
