lamba wa jenereta wa SAIC MAXUS V80 C00015256 wogulitsidwa ku fakitale

Chidziwitso cha zinthu

Gwiritsani ntchito makutu anu kumvetsera kusanthula kwa phokoso losazolowereka la lamba wa injini ya galimoto

Phokoso la lamba nthawi zambiri limatanthauza kuti mphamvu ya friction coefficient ya pamwamba pa lamba yachepa kwambiri ndipo yakhala ikuwonongeka kwambiri. Ngati pali phokoso logwedezeka pamene galimoto ili pansi pa katundu, yang'anani limodzi mwa malamba oyendetsera galimoto ndipo mudzawona kuwonjezeka kwachilendo kwa mphamvu ya resistance kapena spring force pa lamba wotsekereza kapena pa lamba wotsekereza.

Ma tensioner ambiri a lamba odziyimira pawokha ali ndi zizindikiro zosonyeza kutalika kwa lamba pakati pa maziko awo ndi mkono wodziyimira pawokha, motsatira njira ya chute. Chizindikirocho chimakhala ndi pointer ndi zizindikiro ziwiri kapena zitatu, zomwe zimasonyeza kutalika kwa ntchito ya tensioner ya lamba. Ngati pointer ili kunja kwa mtunda uwu, lamba mwina limatambasulidwa kwambiri ndipo liyenera kusinthidwa. Pa magalimoto opanda tensioner ya lamba odziyimira pawokha, yezani ndi choyezera chotambasulidwa cha lamba pakati pa ma pulley awiri. Ngati pali kusiyana ndi mtengo wamba, ndi bwino kusintha lamba.

Ngati lamba woyendetsa galimoto sakupitirira malire ake, ndiye kuti ngati galimoto yanu ili ndi chotenthetsera chokha, muyenera kuisamalira kwambiri. Choyamba, yambani injini, ikani makina othandizira momwe mungathere (monga kuyatsa magetsi, mpweya woziziritsa, kutembenuza mawilo, ndi zina zotero), kenako yang'anani chotenthetsera cha lamba; pamene injini ikugwira ntchito, chotenthetsera cha lamba chiyenera kukhala ndi kuchuluka kochepa kosunthika. Ngati chotenthetsera cha lamba sichikusuntha, zimitsani injini ndikuyisuntha pamanja mkati mwa chitoliro chogwirira ntchito cha chotenthetsera cha lamba, pafupifupi 0.6 cm. Ngati chotenthetsera cha lamba sichikusuntha, zikutanthauza kuti chotenthetsera cha lamba chalephera ndipo chiyenera kusinthidwa pakapita nthawi; ngati kusunthika kwa chotenthetsera cha lamba kupitirira pafupifupi 0.6 cm, zikutanthauza kuti katundu wa kasupe ndi wochepa kwambiri, zomwe zingapangitse lamba kutsetsereka. Mwanjira imeneyi, chotenthetsera cha lamba chokha ndicho chimasinthidwa.

Ngati lamba silinatambasulidwe kwambiri ndipo chotenthetsera chokha chikugwira ntchito bwino, onani ngati pamwamba pa lamba pali galasi lopukutidwa. Uku ndi kutsetsereka kwachizolowezi komwe kumachitika chifukwa cha kusweka kwambiri kwa lamba, ndipo utoto womwe umatuluka pamwamba pa pulley ndiye umboni wabwino kwambiri woti lambayo silikutsetsereka.

Ngati lamba limalira nthawi zambiri munyengo yamvula, ndipo pamwamba pa lamba ndi pulley pali yosalala. Tiyeni tichitenso zomwezo: lolani kasinthidwe kothandizira kagwire ntchito ndi dongosolo lomwe lili pansi pa katundu, pamene mukupopera madzi pa lamba, ndipo ngati likugwedezeka, m'malo mwake lambayo.

Kufuula kwa nthawi yayitali kapena phokoso lamphamvu:

Ngakhale pamwamba pa pulley pali dothi monga tinthu ta mchenga kapena kuyika lamba wogwiritsidwa ntchito kumbuyo kungayambitsenso lamba kupanga phokoso lalitali kapena phokoso lofuula, nthawi zambiri limachitika chifukwa chosagwirizanitsa bwino chipangizo chothandizira.

Ngati phokoso lomwe lili pamwambapa likuchitika pa galimoto yatsopano yomwe idayendetsedwa kale, likhoza kuchitika chifukwa cha zida zoyambirira za fakitale zomwe sizinali zabwino kwenikweni. Yang'anani zida zomwe mukuganiza kuti zikuyambitsa kulephera. Ngati phokoso lomwe lili pamwambapa likuchitika m'galimoto yakale, ndiye kuti muyenera kuganizira ngati zida zina zokhudzana ndi unit yake yothandizira ziyenera kusinthidwa kwathunthu. Yang'anani mosamala zida zomwe mwina zidasinthidwa bwino (monga majenereta, mapampu othandizira chiwongolero, ndi zina zotero) kuti muwone ngati mabulaketi awo oikira ali otetezeka. Zingayambitsenso kusakhazikika bwino kwa pulley.

Monga tafotokozera pamwambapa, dothi kapena mchenga pakati pa lamba ndi pulley zingayambitsenso phokoso lomwe lili pamwambapa, kotero ngati galimotoyo ikugwiritsidwa ntchito pamalo odetsedwa, yang'anani pamwamba pa pulleys zonse kuti muwone ngati pali dothi.

Mwachitsanzo, tengerani lamba wa giya la nthawi, liyenera kusinthidwa nthawi yomweyo mutayika. Ichi ndichifukwa chake njira yozungulira lamba wa giya la nthawi imalembedwa. Ngati lamba wa giya la nthawi wachotsedwa ndikuyikidwa mozondoka chifukwa cha ntchito zina zokonzanso, mudzamva kulira kwakukulu, kofuula pamene lamba likugwira ntchito. Yesani kubweza kumbuyo komwe lamba likuyang'ana ndikuwona ngati vuto latha.

Kulira, kugwedezeka, kulira, kapena kulira:

Phokoso losalekeza kapena logwedezeka lomwe limawonjezeka pamene injini ikukwera, nthawi zambiri limatanthauza kuti ma bearing a makina ozungulira othandizira alibe mafuta okwanira. Phokosoli likhoza kufufuzidwanso pogwiritsa ntchito stethoscope. Kenako chotsani lamba woyendetsa ndikutembenuza gawo lomwe likuganiziridwa kuti ndi lolakwika ndi dzanja. Ngati kuzungulira kuli kovuta kapena phokoso ndi lovuta komanso logwedezeka, musazengereze kusintha bearing kapena kusintha gawo logwirizana. Koma ziyenera kudziwika kuti nthawi iliyonse mukasintha ziwalo za zowonjezera zoyendetsera othandizira, musaiwale kusintha bearing tensioner ndi automatic tensioner. Ngati phokoso losalekeza limasintha pang'onopang'ono kukhala phokoso pamene liwiro la injini likuwonjezeka, zimasonyeza kuti bearing yofananayo idzalephera posachedwa.

Rumble

Rumble ndi phokoso la kugwedezeka kwa lamba, makamaka pamene makina othandizira oyendetsa galimoto akugwira ntchito, injini ikafika pa liwiro linalake, phokoso limawonjezeka kwambiri. Chifukwa cha kulephera kwamtunduwu nthawi zambiri chimakhala chifukwa cha lamba wotumizira mphamvu kukhala womasuka kwambiri, wotambasulidwa kwambiri, kapena chotenthetsera lamba ndi chotenthetsera cha lamba kuwonongeka.
