chipewa ndi chotengera chotulutsa, kugwiritsa ntchito chotengera chotulutsa cha clutch

 

Kutulutsa mphamvuNdi bearing yomwe imagwiritsidwa ntchito pakati pa clutch ndi transmission, nthawi zambiri timaitcha "clutch release bearing". Mukaponda clutch, ngati foloko yaphatikizidwa ndi clutch pressure plate yomwe ikuzungulira mwachangu, bearing iyenera kufunikira kuti ichotse kutentha ndi kukana komwe kumachitika chifukwa cha kukangana mwachindunji, kotero bearing yomwe imayikidwa pamalo awa imatchedwa release bearing. Bearing yolekanitsa imakankhira pressure plate kuti ilekanitse ndi friction plate, motero imadula mphamvu yotulutsa crankshaft.

 

Chotengera chotulutsa clutchzofunikira pakuchita bwino:

 

Kusuntha kwa chimbalangondo cholekanitsa kuyenera kukhala kosinthasintha, popanda phokoso lakuthwa kapena kugwedezeka, malo ake ozungulira sayenera kupitirira 0.60mm, ndipo kuvala kwa mtundu wamkati sikuyenera kupitirira 0.30mm.

 

Mfundo yogwirira ntchito ndi ntchito yachogwirira chotulutsa clutch:

 

Chotchedwa clutch, monga momwe dzinalo likusonyezera, chimagwiritsa ntchito "kulekanitsa" ndi "kuphatikiza" kuti chitumize mphamvu yoyenera. Injini nthawi zonse imakhala ikuzungulira, pomwe mawilo sakuzungulira. Kuti galimotoyo iyimitse popanda kuwononga injini, mawilo ayenera kuchotsedwa mu injini mwanjira ina. Clutch imalamulira kutsetsereka pakati pa injini ndi giya, zomwe zimapangitsa kuti zikhale zosavuta kulumikiza injini yozungulira ku giya yosazungulira.

 

Thechogwirira chotulutsa clutchimayikidwa pakati pa clutch ndi gearbox, ndipo mpando wotulutsa umakhala womasuka pa chowonjezera cha tubular cha bearing cover cha shaft yoyamba ya gearbox, ndipo phewa la bearing lotulutsa nthawi zonse limakhala motsutsana ndi foloko yolekanitsa kudzera mu kasupe wobwerera, ndikubwerera kumalo omaliza, kusunga mpata wa pafupifupi 3 ~ 4mm ndi kumapeto kwa lever yolekanitsa (chala cholekanitsa).

 

Chifukwa chakuti mbale yopanikizira ya clutch, lever yolekanitsa ndi crankshaft ya injini zimayenda molumikizana, ndipo lever yolekanitsa imatha kusuntha mozungulira mozungulira mozungulira mozungulira mozungulira mozungulira mozungulira mozungulira mozungulira mozungulira mozungulira mozungulira mozungulira mozungulira mozungulira mozungulira mozungulira mozungulira mozungulira mozungulira mozungulira mozungulira mozungulira mozungulira mozungulira mozungulira mozungulira mozungulira mozungulira mozungulira mozungulira mozungulira mozungulira mozungulira mozungulira mozungulira mozungulira mozungulira mozungulira, kuti zitsimikizire kuti clutch ikhoza kugwira bwino, kulekanitsako kumakhala kofewa, kuchepetsa kuwonongeka, ndikuwonjezera moyo wa clutch ndi makina onse otumizira.

 

Mfundo zazikulu zoti muzikumbukira mukamagwiritsa ntchitomabearing otulutsa clutch:

 

1. Malinga ndi malamulo oyendetsera ntchito, pewani clutch mukakhala kuti siigwira ntchito mokwanira komanso yosiyana pang'ono, ndipo chepetsani kuchuluka kwa ntchito za clutch.

 

2. Samalani kukonza, ndipo gwiritsani ntchito njira yothira mafuta kuti mulowetse batala ndi njira zothira mafuta nthawi zonse kapena pachaka, kuti likhale ndi mafuta okwanira.

 

3. Samalani kulinganiza cholendewera cholekanitsa clutch kuti muwonetsetse kuti mphamvu yotanuka ya kasupe wobwerera ikutsatira malamulo.

 

4. Sinthani kukwapula kwaulere kuti kukwaniritse zofunikira (30-40mm) kuti kukwapula kwaulere kusakhale kwakukulu kwambiri kapena kochepa kwambiri.

 

5. Chepetsani kuchuluka kwa malo olumikizirana mafupa ndi magawano ndipo chepetsani katundu wokhudzana ndi kugwedezeka.

 

6. Yendani pang'onopang'ono komanso mosavuta kuti ilumikizane ndikulekanitsidwa bwino.

 

Zinthu zomwe zimayambitsa kuwonongeka panthawi yogwiritsa ntchitomabearing otulutsa clutch:

 

1. Mikhalidwe yogwirira ntchito ndi mphamvu ya chogwirira chotulutsa clutch

 

Bearing yolekanitsa imakhudzidwa ndi axial load, shock load ndi radial centrifugal force panthawi yozungulira liwiro lalikulu panthawi yogwiritsa ntchito, ndipo torsional moment imapangidwa chifukwa foloko thrust ndi reaction force ya separation lever sizili pamzere wowongoka womwewo. Clutch release bearing zimakhala ndi mikhalidwe yoyipa yogwirira ntchito, zimazungulira nthawi ndi nthawi pa liwiro lalikulu ndipo zimapirira kukangana kwa liwiro lalikulu, kutentha kwambiri, mafuta oipa, komanso palibe mikhalidwe yozizira.

 

2. Chifukwa cha kuwonongeka kwa bere lotulutsa clutch

 

Kuwonongeka kwa clutch release bearing kumakhudzana kwambiri ndi momwe dalaivala amagwirira ntchito, kukonza, ndi kusintha, ndipo zifukwa za kuwonongeka ndi izi:

 

1) Kutentha kwambiri kumachitika chifukwa cha kutentha kwambiri kwa ntchito

 

Madalaivala ambiri nthawi zambiri amaponda clutch pakati akamatembenuka kapena kutsika, ndipo ena amaikabe mapazi awo pa clutch pedal atatha kuyimitsa giya; Magalimoto ena amakhala ndi kusintha kwakukulu kwa free stroke, kotero kuti clutch siimalekanitsidwa kwathunthu, mu mkhalidwe wotanganidwa pang'ono komanso wosiyana pang'ono, mkhalidwe uwu umayambitsa kukangana kouma ndikupanga kutentha kwakukulu kupita ku bearing yolekanitsa, kutentha kwa shaft bearing kumafika kutentha kwina, batala limasungunuka kapena kuchepetsedwa ndikutuluka, kotero kuti kutentha kwa bearing yolekanitsa kumawonjezeka kwambiri, ndipo kumayaka kutentha kukafika pamlingo winawake.

 

2) Kusowa mafuta odzola ndi kuwonongeka

 

Pa 360111 separation bearing, chivundikiro chakumbuyo cha bearing chiyenera kutsegulidwa ndikudzazidwa ndi mafuta panthawi yokonza kapena pamene transmission yachotsedwa, kenako chivundikiro chakumbuyo chikhoza kukonzedwanso; Pa 788611K separation bearing, ikhoza kuchotsedwa ndikunyowa mu mafuta osungunuka, kenako nkuchotsedwa mutazizira kuti mukwaniritse cholinga cha mafuta. Pantchito yeniyeni, dalaivala ndi wosavuta kunyalanyaza izi, zomwe zimapangitsa kuti mafuta asakhalepo mu clutch release bearing. Ngati palibe mafuta okwanira kapena ochepa, nthawi zambiri kuwonongeka kwa separation bearing kumakhala kochulukirapo mpaka kangapo kuposa kuwonongeka pambuyo pa mafuta. Pamene kuvala kukukwera, kutentha kumawonjezekanso kwambiri, zomwe zimapangitsa kuti iwonongeke mosavuta.

 

3) Ulendo waulere ndi wochepa kwambiri kapena kuchuluka kwa katundu ndi kwakukulu kwambiri

 

Malinga ndi zofunikira, kusiyana pakati pa clutch release bearing ndi release lever ndi 2.5mm, ndipo kuyenda kwaulere komwe kumawonetsedwa pa clutch pedal ndi 30-40mm. Malinga ndi mfundo ya kulephera kutopa, bearing ikagwira ntchito nthawi yayitali, kuwonongeka kumakhala kwakukulu; Nthawi zambiri ikadzaza, zimakhala zovuta kwambiri kuyambitsa kulephera kutopa kwa bearing release. Ndipo nthawi yayitali yogwira ntchito, kutentha kwa bearing kumakhala kokwera, kumakhala kosavuta kuwotcha, zomwe zimachepetsa moyo wa ntchito ya separation bearing.

 

4) Kuwonjezera pa zifukwa zitatu zomwe zili pamwambapa, kaya chopatulira chopatuliracho chakonzedwa bwino komanso ngati kasupe wobwerera wa chopatuliracho ndi wabwino zimakhudzanso kwambiri kuwonongeka kwa chopatuliracho.

 

Kukonza ma bere otulutsa clutch:

 

Konzani mphete yamkati ya chopatulira cholekanitsa ndi dzanja, tembenuzani mphete yakunja, ndikuyika mphamvu mbali imodzi nthawi imodzi, ngati pali kutsekeka kapena kumverera koonekeratu kwa mpata, chopatulira cholekanitsa chiyenera kusinthidwa. Maberiya olekanitsa nthawi zambiri amakhala odzaza mafuta kamodzi kokha. Dulani ndi kuyeretsa momwe mukufunira panthawi yokonza. Ngati pali dothi, mutha kupukuta pamwamba ndi nsalu yoyera.
