Njira ya mphirandi mphira ndi zitsulo kapena ulusi wazinthu zopangidwa ndi tepi ya mphete, zokhala ndi kupanikizika pang'ono, kugwedezeka kwakukulu, kugwedezeka kwazing'ono, phokoso lochepa, kuyenda bwino kwamtunda, kusawonongeka kwa msewu, kuthamanga mofulumira, khalidwe laling'ono ndi makhalidwe ena, akhoza pang'ono. sinthani matayala ndi mayendedwe achitsulo pamakina aulimi, makina omanga ndi magalimoto oyendetsa gawo loyenda. Ma track a mphira amakulitsa kuchuluka kwa kugwiritsa ntchito makina am'manja omwe amatsatiridwa ndi mawilo, kuthana ndi zovuta zosiyanasiyana zapamtunda pamakina. Japan Bridgestone Corporation inali yoyamba kupanga bwino nyimbo za rabara mu 1968.

Kukula kwa njanji za rabara ku China kunayamba kumapeto kwa zaka za m'ma 1980, ndipo tsopano kwapanga kupanga kwakukulu, ndi zomera zoposa 20 zopanga. M'zaka za m'ma 1990, Zhejiang Linhai Jinlilong Shoes Co., Ltd. adapanga mphete.mphira nyimbo zitsuloChingwe cholumikizana popanda kupanga ndikufunsira setifiketi, yomwe idayala maziko amakampani aku China opangira mphira kuti apititse patsogolo bwino zinthu, kuchepetsa ndalama komanso kukulitsa luso lopanga. Ubwino wa njanji za rabara za ku China ndizochepa kwambiri komanso kusiyana pakati pa zinthu zakunja ndipo kuli ndi phindu lamtengo wapatali. Nkhaniyi ikuwonetsa mitundu ya nyimbo za raba, zofunikira pakugwirira ntchito, kapangidwe kazinthu ndi njira zopangira.

Zosiyanasiyana ndi zofunika magwiridwe antchitots

1. 1 Zosiyanasiyana
(1) Malinga ndi njira yoyendetsera galimoto, anjira ya mphiraakhoza kugawidwa mu mtundu gudumu dzino, gudumu dzenje mtundu ndi mphira dzino pagalimoto (coreless golide) mtundu malinga ndi galimoto akafuna. The gudumu dzino mphira njanji ali pagalimoto dzenje, ndi galimoto dzino pa galimoto gudumu amalowetsedwa mu dzenje pagalimoto kupanga njanji kusuntha. The gudumu anabala mphira njanji okonzeka ndi zitsulo kufala mano, amene anaikapo mu mabowo pa pulley ndi mauna kufala. Njira zopangira mphira zokhala ndi mphira zimagwiritsa ntchito mabampu a mphira m'malo motumiza zitsulo, ndipo gawo lamkati la njanji limalumikizana ndi pamwamba pa mawilo oyendetsa, kufalikira kwa mikangano.
(2) Malinga ndi ntchito njanji mphira malinga ndi ntchito akhoza kugawidwa mu ulimi makina mphira njanji, kumanga makina mphira njanji, zoyendera galimoto mphira njanji, matalala akusesa magalimoto njanji mphira ndi asilikali galimoto mphira njanji.

1. 2 Zofunikira zoyambira ntchito

Zofunikira pakugwirira ntchito kwa njanji za rabara ndikukokera, kusaduka, kukana kugwedezeka komanso kulimba. Kukokera kwa njanji za rabara kumagwirizana ndi mphamvu zake zolimba, kumeta ubweya, bandwidth, lateral rigidity, phula ndi kutalika kwa block block, komanso zimakhudzidwa ndi momwe msewu uliri komanso katundu.

Kuthamanga kwa Rubber track traction ndikwabwinoko. Kulephera kopanda gudumu kumadalira makamaka kukula kwa gudumu loyendetsa, dongosolo la gudumu komanso kutalika kwa kalozera. De-wheeling nthawi zambiri imapezeka pakati pa gudumu yogwira ntchito kapena gudumu logwedeza ndi rotor, ndi kuuma kokhotakhota, kusinthasintha kwapakati, kusinthasintha kwautali, phula ndi kutalika kwa mphira wa mphira kumakhudzanso kwambiri kusagwirizana ndi gudumu.

Kuchotsa gwero la kugwedezeka ndi njira yabwino yochepetsera kugwedezeka ndi phokoso, ndipo kugwedezeka kwa njanji ya mphira kumagwirizana ndi phula, kasinthidwe ka rotor, pakati pa mphamvu yokoka, ntchito ya rabara ndi kasinthidwe ka block block. Kukhalitsa kumawonetseredwa ndi kuthekera kwa njanji za mphira kupirira abrasion, kudula, puncture, kusweka ndi kukwapula. Pakadali pano, njanji za rabara zikadali zowopsa, ndipo moyo wazinthu zakunja zakunja ndi pafupifupi 10,000 km. Kuphatikiza pa mawonekedwe opatsirana ndi ma traction, magwiridwe antchito a rabara ndi chinthu chofunikira chomwe chimakhudza kulimba kwa njanji za rabara. Zakuthupi za mphira sizingokhala ndi zinthu zabwino zakuthupi, zowoneka bwino komanso kukana kukalamba kwanyengo, komanso zimafunikanso kukhala ndi zinthu zabwino zomatira, pazinthu zina zapadera, zida za mphira ziyeneranso kukhala ndi mchere ndi alkali kukana, kukana mafuta, kukana kuzizira komanso kuletsa moto komanso ntchito zina.
