Momwe mungadziwire kuti ndi ma CV ati omwe akudumpha

Mayendedwe a mawilo owongolera agalimoto ndi ophatikizika amitundu iwiri yothamanga (ma CV joints) olumikizidwa ndi shaft yokhala ndi malekezero opindika. Kunena zowona, kapangidwe kofananako kamapezekanso kumbuyo kwa chitsulo choyendetsa kumbuyo ndi bokosi la gear mu crankcase yosiyana, koma zowunikira nthawi zambiri zimafunikira ndi gudumu lakutsogolo, lomwe limagwira ntchito movutikira kwambiri potengera ma ngodya zotengera makokedwe.

Njira yodziwira kuti ndi ziti mwazitsulo zinayi za CV zomwe zikugwira ntchito kumeneko zatha kapena zayamba kugwa nthawi zambiri zimakhala zovuta ndipo zimafuna kutsata njira yolondola kuti tipewe kutaya nthawi ndi ndalama.

CV yakunja ndi yamkati yolumikizana: zosiyana ndi mawonekedwe

Hinge yakunja imawerengedwa kuti yolumikizidwa ndi gudumu, ndipo yamkati imakhala pambali pachotulutsa cha gearbox kapena drive axle reducer.

Ma node onsewa amasiyana pamapangidwe, omwe amalumikizidwa ndi zofunika kwa iwo:

• pa ntchito, pagalimoto msonkhano ayenera kusintha kutalika kwake pa kusamutsidwa kwa kuyimitsidwa kuchokera malo kwambiri ofukula malo ena, ntchito imeneyi anapatsidwa kwa hinge mkati;
• cholumikizira chakunja cha CV chikuchita kuonetsetsa kuti gudumu lakutsogolo likuyenda bwino, lomwe limaperekedwa pamapangidwe ake;
• ma splines akunja a "grenade" akunja amatha ndi gawo la ulusi, pomwe nati imakulungidwa, kumangiriza mitundu yamkati ya gudumu;
• mapeto a spline mkati mwa galimotoyo akhoza kukhala ndi annular groove kwa mphete yosungirako, kapena kukhala ndi zotayirira, shaft imagwiridwa mu crankcase ndi njira zina;
• hinge yamkati, chifukwa chapang'ono pang'ono pamakona, nthawi zina sichimapangidwa molingana ndi kapangidwe ka mpira wachisanu ndi chimodzi, koma mu mawonekedwe a tripoid, ndiye kuti, ma spikes atatu ndi singano zokhala ndi mipikisano yakunja yozungulira, iyi ndi champhamvu, cholimba, koma sichigwira ntchito bwino pamakona ofunikira.

Kupanda kutero, node ndizofanana, zonse zimakhala ndi thupi lokhala ndi ma grooves a mipira kapena ma spikes, khola lamkati, ma splines akukhala pa shaft yoyendetsa ndi cholekanitsa chomwe chimayika mipira ikamathamanga m'malo ogwirira ntchito.

Zoyambitsa ndi zizindikiro za kulephera kwa nthawi zonse liwiro mfundo

Chifukwa chachikulu cha kulephera kwa hinge ndiko kuvala kwa ma grooves amitundu yonse, olekanitsa ndi mipira. Izi zitha kuchitika mwachilengedwe, ndiye kuti, pamaso pamafuta apamwamba kwambiri kwa nthawi yayitali, pamtunda wamakilomita masauzande ambiri kapena kuthamanga.

Kuvala mwachangu kumayamba ndi kulowa kwa ma abrasives kapena madzi mu chivundikiro choteteza zotanuka. Ndi chowonjezera chotere ku mafuta, msonkhano umakhala makilomita chikwi kapena kuchepera. Ndiye zizindikiro zoyamba za mavuto zimayamba kuonekera.

Mipira ikathamangira mkati, makola onsewa amalumikizana ndendende ndi mipata yochepa. Mayendedwe ogudubuza ndi otsetsereka amasinthidwa ndendende, nthawi zambiri ngakhale posankha magawo. Hinge yotere imagwira ntchito mwakachetechete potumiza torque iliyonse yovotera komanso mbali iliyonse kuchokera pagawo lomwe mwapatsidwa.

Mipata ikangowonjezereka chifukwa cha kuvala kapena geometry ya grooves imasokonekera, kugogoda kumawoneka mu hinge chifukwa cha kusankha kwa backlashes ndi crunches chifukwa cha ukwati wamba. Kutumiza kwa torque kumachitika ndi ma jerks a mawonekedwe osiyanasiyana.

Momwe mungayang'anire mgwirizano wakunja wa CV

Chovuta kwambiri cha mbali yakunja ya galimotoyo chidzakhala kutumiza torque yayikulu pamtunda waukulu. Ndiko kuti, ngati hinge yatha, ndiye kuti mtengo wapamwamba wa backlash ndi ma acoustic accompaniment amakwaniritsidwa ndendende m'njira zotere.

Ndiye njira yodziwira:

• poyendetsa pa liwiro lotsika, mawilo amatembenuzidwira ku malo owopsa kwambiri ndipo kuthamangitsidwa kwakuthwa kumachitidwa, crunch idzamveka kuchokera ku CV yolakwika;
• pobwereza ndondomekoyi mbali zonse ziwiri, ziganizo zimatchulidwa, pamene zimamveka kuti mbali ya kuzungulira kwa gudumu lamkati pokhudzana ndi njira ya gudumu ndi yaikulu kuposa yakunja;
• ngati mukukayikira, galimotoyo imapachikidwa pamtunda, zonsezi zimabwerezedwa, ndipo katswiri wodziwa matenda omwe ali pansi pa galimotoyo amamvetsera mfundo zenizeni, katundu wofunikira amafananizidwa ndi nthawi yomweyo kukanikiza accelerator ndi ma pedals.

Kuzindikira komaliza kumapangidwa mutachotsa choyendetsa pamakina ndikudula ma hinges kuchokera pamenepo. Kubwerera kumbuyo kudzawoneka bwino pamene khola lakunja likugwedezeka ndi lamkati, kuvala kwa groove kumawonekera pambuyo pa kusungunuka ndi kuchotsa mafuta, ndipo ming'alu ya olekanitsa ikuwonekera bwino pamtunda wake wouma.

Kuyang'ana mkati "grenade"

Mukayang'ana popita, cholumikizira chamkati chiyeneranso kupangidwira m'malo ovuta kwambiri ogwirira ntchito, ndiye kuti, ma angles apamwamba. Palibe chomwe chimadalira kutembenuza chiwongolero apa, kotero muyenera kuyendetsa galimoto momwe mungathere, kusuntha mu arc pa liwiro lalikulu pansi pa mphamvu zonse.

Kuphwanyidwa kuchokera mkati mwa galimoto kumagwirizana ndi trajectory kumatanthawuza kuvala pa hinge yamkati pa galimotoyo. Mbali inayi, m'malo mwake, idzachepetsa mbali yopuma, kotero kuti crunch ikhoza kuwonekera pamenepo kuchokera ku mfundo yomwe ili yovuta kwambiri.

Mayeso okwera amatha kumangidwa mofananamo, kukweza galimotoyo ndi mabuleki, ndikusintha ma angles a kuyimitsidwa kwa mikono pogwiritsa ntchito hydraulic props. Panthawi imodzimodziyo, ndizosavuta kuyesa kukhalapo kwa ma backlashes ndi momwe zimakwirira. Anthers ong'ambika kwautali okhala ndi dothi ndi dzimbiri mkati mwake zikutanthauza kuti hinji iyenera kusinthidwa mosadziwika bwino.

Chifukwa chiyani crunch ndi yowopsa?

Hinge yophwanyika sikhala nthawi yayitali, zotengera zotere zimawononga kwambiri. Chitsulocho chimatopa, chophimbidwa ndi makina a microcracks ndi pitting, ndiko kuti, kuphulika kwa malo ogwirira ntchito a njanji.

Khola lolimba kwambiri koma lophwanyika lidzang'ambika, mipira imayenda mosintha ndipo hinge idzaphwanyidwa. Kuyendetsako kudzawonongedwa ndipo kusuntha kwina kwagalimoto kumatheka kokha pagalimoto yokokera, ndipo kutayika kwa liwiro lalikulu kulinso kosatetezeka.

Panthawi imodzimodziyo, pakhoza kukhala vuto la gearbox, lomwe lagundidwa ndi shaft yoyendetsa.

Kodi ndizotheka kukonza cholumikizira cha CV kapena kungosintha

M'zochita, kukonzanso kwa mgwirizano wa CV sikutheka chifukwa cha kulondola kwakukulu kwa kupanga kwake, zomwe zikutanthauza kusankha magawo. Hinge yomwe yasonkhanitsidwa kuchokera ku magawo osiyanasiyana imatha kugwira ntchito mwanjira ina, koma palibe chifukwa cholankhula za kusagwirizana ndi kudalirika.

Msonkhano wotopa uyenera kusinthidwa kukhala msonkhano, popeza zolumikizira zamtengowo zimathanso, pambuyo pake gululo lidzagogoda ngakhale ndi mahinji atsopano. Koma ndi okwera mtengo kwambiri, choncho amaperekedwa kokha ndi opanga zida zosinthira zoyambirira.
