Mgwirizano Wapafupipafupi (Wophatikizira wa CV)

Mahinji (omwe nthawi zambiri amatchedwa hinge ya homokinetic (kuchokera ku inayo -gr. popanda kukangana kwambiri kapena kumenyedwa. Amagwiritsidwa ntchito makamaka pagalimoto zoyenda kutsogolo. 

Magalimoto amatetezedwa ndi mphira, womwe nthawi zambiri umadzazidwa ndi mafuta a molybdenum (omwe ali ndi 3-5% MoS2). Pankhani ya ming'alu yamanja, madzi kulowa mkati amatsogolera ku zomwe MoS2 (2) H2O MoO2 (2) H2S, popeza molybdenum dioxide imakhudza kwambiri. 

История 

Cardan shaft, imodzi mwanjira zoyambirira zopatsira mphamvu pakati pa masheya awiri pakona, idapangidwa ndi Gerolamo Cardano m'zaka za zana la 16. Sanathe kuyendetsa liwiro nthawi zonse pakusinthasintha ndipo adakonzedwa ndi Robert Hooke m'zaka za zana la 17, yemwe adalimbikitsa kulumikizana koyamba kwanthawi zonse, komwe kumakhala ma shafts awiri othamangitsidwa ndi madigiri 90 kuti athetse kusinthasintha kwakanthawi. Tsopano timatcha gimbal iwiri. 

Zipangizo zoyambirira zamagalimoto 

Makina oyambirira oyendetsa ma gudumu akutsogolo omwe amagwiritsidwa ntchito mu ma axle akutsogolo a Citroën Traction Avant ndi Land Rover ndi magalimoto ena ofanana ndi ma gudumu anayi amagwiritsa ntchito malo olumikizirana m'malo molumikizana ndi liwiro lokhazikika. Ndiosavuta kupanga, amatha kukhala amphamvu kwambiri, ndipo amagwiritsidwabe ntchito kuti azitha kulumikizana ndi ma shafts ena oyendetsa pomwe palibe kuyenda mwachangu. Komabe, zimakhala "zokhotakhota" komanso zovuta kuzitembenuza zikugwira ntchito pamakona apamwamba. 

Malo oyamba okhala ndi ma velocities ofanana 

Makina oyendetsa kutsogolo akayamba kutchuka komanso magalimoto ngati BMC Mini amagwiritsa ntchito ma mota ophatikizika, zovuta zamagudumu akutsogolo zikuwonekera kwambiri. Kutengera kapangidwe kovomerezeka ndi Alfred H. Rsepp mu 1927 (Tracta loop, yopangidwa ndi Pierre Fenay for Tracta, inali ndi setifiketi mu 1926), kulumikizana kwanthawi zonse kumathetsa mavutowa. Amapereka magetsi osalala ngakhale ali ndi mawonekedwe osiyanasiyana opindika. 

Kulumikiza kwanjira

Rzeppa hinge 

Chingwe cha Rzeppa (chopangidwa ndi Alfred H. Rserra mu 1926) chimakhala ndi thupi lozungulira lokhala ndi mabowo 6 akunja mu chipolopolo chachikazi chofananira. Malo aliwonse amatsogolera mpira umodzi. Shaft yolowererayo imakwanira pakatikati pa "gear" yayikulu yazitsulo yomwe imakhala mkati mwa khola lozungulira. Selo ndi lozungulira, koma limakhala lotseguka, ndipo nthawi zambiri limakhala ndi mabowo asanu ndi limodzi mozungulira. Khola ndi magiya izi zimayikidwa mu chikho cholumikizidwa chomwe chimamangiriridwa kutsinde. Mipira yayikulu isanu ndi umodzi yazitsulo imakhala mkati mwa mayikowo ndipo imalowa m'mabowo a khola olowera muzitsulo za sprocket. Linanena bungwe kutsinde chikho umadutsa zimakhudza gudumu ndipo amatetezedwa ndi nati shaft. Kulumikizana kumeneku kumatha kupirira kusintha kwakukulu ngodya pomwe magudumu akutsogolo amasunthidwa ndi chiwongolero; Mabokosi amtundu wa Rzeppa amatha kusinthidwa ndi madigiri 45-48 pomwe ena amatha kusinthidwa ndi madigiri 54.

Hinge zala zitatu

Zolumikizana izi zimagwiritsidwa ntchito kumapeto kwa mkati mwa ma shafts agalimoto. Yopangidwa ndi Michel Orijn, Glaenzer Spicer waku France. Hingeyo ili ndi chitsamba cha zala zitatu chomwe chili ndi malo otsetsereka patsinde, ndipo pa zala zazikuluzikulu pali tchire lowoneka ngati mbiya pazitsulo za singano. Amabwera mu kapu yokhala ndi njira zitatu zofananira zomwe zimalumikizidwa ndi kusiyana. Popeza mayendedwe ali mumzere umodzi wokha, dongosolo losavutali limagwira ntchito bwino. Amalolanso kusuntha kwa axial "dipping" kwa shaft kuti ma motor agwedezeke ndi zotsatira zina zisapanikizike. Makhalidwe abwino ndikuyenda kwa axial shaft kwa 50 mm ndi kupatuka kwa angular kwa madigiri 26. Hinge ilibe mahinji ambiri ngati mahinji ena ambiri, koma nthawi zambiri imakhala yotsika mtengo komanso yothandiza kwambiri. Chifukwa chake, nthawi zambiri amagwiritsidwa ntchito pamakina oyendetsa kumbuyo kapena mkati mwa magalimoto akutsogolo komwe kumayenda komwe kumafunikira kumakhala kochepa.

Mafunso ndi Mayankho:

Kodi mgwirizano wokhazikika umagwira ntchito bwanji? The torque imachokera ku kusiyana kudzera muzitsulo zomwe zimagwirizanitsidwa ndi hinges. Zotsatira zake, ma shaft onse, mosasamala kanthu za ngodya, amazungulira pa liwiro lomwelo.

Kodi ma CV joints ndi chiyani? Mpira (mtundu wa serial wothandiza kwambiri), katatu (zodzigudubuza zozungulira, osati mipira), zophatikizika (mahinji amtundu wa cardan, olimba kwambiri), kamera (yomwe imagwiritsidwa ntchito pamagalimoto olemera).
