Chitukuko cha mapangidwe amtundu wa crawler oyenda pansi kunyumba ndi kunja

1.2.1 Kafukufuku ndi Chitukuko Kumayiko Ena

Udindo wa undercarriage ndikuthandizira ndikuyika injini ndi zida zake kuti apange mawonekedwe onse agalimoto, ndikutumiza mphamvu kuti galimotoyo isunthike ndikuwonetsetsa kuyendetsa bwino.

M'mayiko akunja, chitukuko cha zokwawa zoyenda pansi zinali kale.Kumayambiriro kwa chaka cha 1986, WCEvans ndi DSGove anamaliza kafukufuku wokhudza kukopa kwa njanji ya rabara ndi thirakitala yoyendetsa magudumu anayi pamalo olimba ndi malo olimidwa.Pansi pa kavalo wapansi womwewo, mphamvu yokoka ya chokwawa cha rabara ndi yapamwamba kuposa yamphamvu yokoka.Kukokera kokwanira bwino ndi 85% mpaka 90% pa malo olimidwa ndi nthaka yolimba, ndi 70% mpaka 85% kwa mathirakitala oyendetsa magudumu anayi.Kuyambira nthawi imeneyo, pakhala pali kafukufuku wambiri woyesa ma thirakitala a mphira ndi mathirakitala oyendetsa magudumu anayi, monga kuyesa kwa mathirakitala a mphira ndi mathirakitala oyendetsa magudumu anayi pa nthaka yamitundu inayi (osalimidwa, opukutira, olima oat). chiputu ndi chiputu cha chimanga).Ubale pakati pa magwiridwe antchito (chiwerengero champhamvu champhamvu, traction coefficient ndi slip rate), etc.

Pankhani yakutukuka kwa msika, mathirakitala okwawa omwe amapangidwa kunja ali ndi mpikisano wamphamvu pamlingo waukadaulo komanso kuthekera kopanga.Mpikisano wapadziko lonse wa mathirakitala okwawa ndi mzere wa Caterpillar wa mathirakitala okwawa mphira.Zogulitsa za YTO sizipikisana pamlingo waukadaulo kapena kuthekera kopanga, mtengo wokha ndiwowoneka bwino, koma kuchokera pakuwunika kuchuluka kwamitengo yamitengo, zopangidwa za YTO zikadali pamavuto.Chifukwa chake, mathirakitala amphamvu kwambiri amakampani opanga mphira adzagulitsidwa pamsika posachedwa, kuti aphatikizire msika wanthawi zonse ndikupangitsa masewerawo kukhala opambana.

1.2.2 Kafukufuku wapakhomo ndi chitukuko

dziko langa lili ndi mbiri yochepa yopanga crawler undercarriage, yomwe kwenikweni ndi yofanana ndi kukula kwa cranes.Poyerekeza ndi mayiko otsogola padziko lapansi, zokwawa zapakhomo zimakhala ndi luso lochepa komanso lochepa la serialization, ndipo pali kusiyana kwina pakupanga ndi kupanga.M'zaka zaposachedwa, kukula kwachangu kwa crawler crawler kwabweretsa mwayi wopanga ma crawler undercarriage, ndipo mndandanda wasinthidwa mosalekeza.

Kwa zaka zoposa 20, mayunivesite ena apakhomo, mabungwe ofufuza ndi mabizinesi achita kafukufuku wokhudza magalimoto omwe amatsatiridwa ndi mphira, monga: China Agricultural Mechanisation Research Institute ndi Nanjing Agricultural Mechanisation Research Institute panjira yokolola mpunga, Qingdao Institute of Architecture ndi Engineering Kafukufuku woyesera pa kupanikizika kwapansi kwa mano oyambira a njanji ya mphira, kafukufuku wa thirakitala ya labala yopangidwa ndi China YTO Group Co., Ltd. kutsatira makamaka kumayambitsa kafukufuku wa mathirakitala a labala.Mu 1994, China YTO Group Co., Ltd. idachita mayeso ofananiza pogwiritsa ntchito chokwawa chachitsulo ndi chokwawa cha raba pa thirakitala yokwawa yokhala ndi mphamvu ya 3 t, ndipo mayesowo adachitika pamalo otayika kwambiri.Pa nthawi yomweyo, undercarriage yoyenera nayenso anayamba kumlingo wakutiwakuti.Kuyambira pamenepo, YTO yakhala ikuyesanso kugwiritsa ntchito mathirakitala ndi ma bulldozer pogwiritsa ntchito njanji za rabara.Ndi kuyesa kukana kwa njanji ya rabara, kuyesa kwa njanji ya mphira, kuyesa moyo wa njanji ya mphira, kuyesa kudalirika kwa njanji ya rabara yokhala ndi zida zosiyanasiyana, kuyesa kwa elongation kwa njanji ya rabara ndi ntchito wamba. kutsimikizira.

Mathilakitala a Crawler ndi zinthu zopunduka pamsika wakunyumba akadali olamulidwa ndi zinthu za YTO.Kugulitsa kwazinthu zotere kumakhala kosinthasintha chifukwa cha chikoka cha mfundo zazikulu za dziko.Kaya ngati makina omangira, zokoka kapena mphamvu zoyendetsera ntchito yaulimi, kapena ngati chotengera chapansi pamakina aulimi, ntchito zake sizingasinthidwe kwathunthu ndi mathirakitala amawilo.Komabe, kukhudzidwa ndi ndondomeko za dziko ndi chitukuko cha mathirakitala othamanga kwambiri, zidzakhala zovuta mumpikisano wamsika pakapita nthawi.Mwachidule, njira yachitukuko cha kanyumba kakang'ono kamene kamayenderana ndi chokwawa, monga njira yoyendetsera makina okhudzana, nthawi zonse imazungulira pa chitukuko cha chitetezo ndi kudalirika, chitonthozo chogwira ntchito, kuteteza chilengedwe ndi kupulumutsa mphamvu.Pachifukwa ichi, ntchito zapakhomo ndi zakunja zakhala zikuyenda bwino nthawi zonse.
