Magawo operekera ma Hub

 

Thechogwirira mawilondi chimodzi mwa zigawo zofunika kwambiri pa galimoto, ntchito yake yayikulu ndikunyamula katundu ndikupereka chitsogozo cholondola cha kuzungulira kwa wheel hub, zomwe zimafuna kuti inyamule osati katundu wozungulira komanso katundu wozungulira.

 

Ma bearing achikhalidwe a mawilo agalimoto amapangidwa ndi magulu awiri a ma bearing ozungulira kapena ma bearing a mpira, ndipo ma bearing amayikidwa, kupakidwa mafuta, kutsekedwa ndipo kusintha kwa malo kumachitika mu mzere wopanga magalimoto.

 

Chipinda chonyamulira ma hub chimapangidwa pogwiritsa ntchito ma bearing a mpira wolumikizana ndi ma bearing ozungulira opindika, omwe amaphatikiza ma bearing awiri, omwe ali ndi magwiridwe antchito abwino, kusintha kwa malo olumikizira kumatha kuchotsedwa, kulemera kopepuka, kapangidwe kakang'ono, mphamvu yayikulu yonyamula katundu, mafuta amatha kuyikidwa pasadakhale kuti ma bearing otsekedwa, ma hub seal akunja amachotsedwa ndipo alibe kukonza, ndi zina zotero, zomwe zakhala zikugwiritsidwa ntchito kwambiri m'magalimoto, ndipo pang'onopang'ono zakulitsa kagwiritsidwe ntchito ka magalimoto akuluakulu.

 

1. Mbadwo wa ma hub bearing units

 

Kugwiritsa ntchito mawilo oyendetsa magalimoto ang'onoang'ono komanso apakatikati

 

Mbadwo woyamba wa ma hub bearing units ndiwo umagwiritsidwa ntchito kwambiri padziko lonse lapansi. Ndiwo chisankho choyamba cha ma drive wheel ang'onoang'ono komanso apakatikati.

 

M'badwo woyambamayunitsi operekera zida za hubIli ndi mizere iwiri ya mabearing a mpira wolumikizana ndi angular okhala ndi mphete zofanana ndi ma seti a mpira kuti apereke malo ofunikira a axial. Ngodya yolumikizira imakonzedwa bwino kuti ipereke kunyamula kwapadera komanso kupirira mikhalidwe inayake ya katundu wa magudumu. Zinthu zazikulu ndi izi:

 

Amasamalira bwino kwambiri katundu wogwiritsidwa ntchito pa bere panthawi yokhotakhota

Khola limapangidwa ndi polyamide yolimbikitsidwa ndi ulusi wagalasi

 

Mafuta ogwira ntchito bwino kwambiri, ogwiritsidwa ntchito pa ntchito, otsekedwa kwa moyo wonse

 

Mapangidwe osiyanasiyana a zisindikizo amapezeka kuti agwiritsidwe ntchito m'njira zosiyanasiyana zoyendetsera mawilo

 

Mphete ya ABS pulse ikhoza kuyikidwa pa mphete yozungulira

 

2. Mbadwo wachiwirigawo lothandizira la hub

 

Yoyenera kugwiritsidwa ntchito pamagalimoto apakatikati pogwiritsa ntchito mawilo osayendetsedwa komanso oyendetsedwa

 

Mu ntchito yodziwika kwambiri ya hub bearing unit ya m'badwo wachiwiri, brake disc kapena drum ndi gudumu zimayikidwa pa flange yozungulira. Kapangidwe ka hub bearing unit ya m'badwo wachiwiri kamakhala ndi mphete ya flange yokhala ndi ma bolts olumikizidwa pa knuckle. Hub unit ya m'badwo wachiwiri nthawi zambiri imagwiritsidwa ntchito ndi mphete yakunja yozungulira ya mawilo akutsogolo kapena akumbuyo osayendetsedwa.

 

3. Mibadwo itatu yamayunitsi operekera zida za hub

M'badwo wachitatugawo lothandizira la hubIzi zimachitika poika flange mu mphete yonyamula katundu yosazungulira ndi flange ina mu mphete yozungulira ya bearing. Mphete yaying'ono yozungulira yamkati imayikidwa pa mphete yamkati ya flange yozungulira kuti iwonjezere mphamvu yonyamula katundu.

Ndi yoyenera kugwiritsa ntchito mawilo oyendetsa ndi osayendetsa m'magalimoto apakati ndi akuluakulu

 

Mu ntchito ya gawo lachitatu la ma hub bearing unit, brake disc kapena drum ndi gudumu zimayikidwa pa flange yozungulira. Flange yozungulira iyi nthawi zambiri imapangidwa ndi makina pambuyo pa ma bearing assembly kuti ikwaniritse kulekerera kochepa kwambiri kwa lateral run-out, zomwe zimathandiza kuchepetsa kugwedezeka ndi phokoso panthawi ya braking.

 

4. Thechogwirira cha hubChida chokhala ndi sensa ya ABS chimaphatikizapo makamaka flange, thupi lozungulira giya la mphete, kusonkhana kotseka ndi hub, ndipo chili ndi sensa ya ABS pa hub, ndipo chitsulo cha maginito mu sensa ya ABS chimayikidwa pa thupi lozungulira giya la mphete ndipo chikugwirizana nacho; Thupi lozungulira giya la mphete limalumikizidwa mokhazikika ndi flange. Sensa ya ABS imaphatikizapo chipolopolo, maginito ndi coil, maginito amayikidwa pa thupi lozungulira giya la mphete, ndipo maginito amafanana ndi thupi lozungulira giya la mphete; Ma coil amalumikizidwa ndi mawaya a chizindikiro ndi mapulagi. Thupi lozungulira giya la mphete limalumikizidwa ndi flange ndi ma splines. Mbali yomaliza ya flange imaperekedwa ndi mabowo omwe amafanana ndi ma bolts, omwe amatha kulumikizidwa mwachindunji ndi zoyimitsidwa, zida zoyendetsera mabuleki ndi matayala. Pali groove yolumikizidwa mkati mwa dzenje lamkati la flange, lomwe lingagwiritsidwe ntchito ndi shaft yoyendetsa liwiro lokhazikika. Zotsatira zabwino za chitsanzo chothandizira ndikuti: kapangidwe kameneka kamalowa m'malo mwa kuphatikiza kwa knuckle yoyendetsera galimoto yoyambirira, hub ya wheel, bearing, zonse zimagwirizanitsa ntchito za zitatu kukhala chimodzi, ndipo zimachepetsa kwambiri kuchuluka kwa kapangidwe koyambirira, zimachepetsa kulemera, komanso zimathandizira kwambiri kudalirika
