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 oyendetsa magudumu oyambilira omwe amagwiritsidwa ntchito mu Citroën Traction Avant ndi Land Rover kutsogolo ma axles ndi magalimoto ofanana onse oyendetsa magalimoto ankagwiritsa ntchito zoyendetsa m'malo mwa ma velocity a CV pafupipafupi. Ndiosavuta kupanga, atha kukhala olimba modabwitsa, ndipo amagwiritsidwabe ntchito kupangitsa kulumikizana kosinthika m'mayendedwe ena oyendetsa kumene kulibe kuyenda mwachangu. Komabe, amakhala "osokonekera" ndipo amakhala ovuta kutembenuka akamagwira ntchito mozama.

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.

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

Mahinji awa amagwiritsidwa ntchito kumapeto kwenikweni kwa zoyendetsa zamagalimoto. Yopangidwa ndi Michel Orain, Glaenzer Spicer waku France. Chipindacho chimakhala ndi chala chazala zitatu chokhala ndi mipata yolowera ku shaft, ndipo zala zazikulu za m'manja zili ndi zotchinga zooneka ngati mbiya pamagwiridwe a singano. Amakwanira chikho chokhala ndi njira zitatu zofananira. Popeza pali gawo limodzi lokha loyenda, njira yosavuta imeneyi imagwira ntchito bwino. Amalolezanso kuyenda kwa axial "kumiza" kwa shaft kuti kugwedezeka ndi zovuta zina zisatsimikizire mayendedwe. Mitundu yodziwika ndi 50mm shaft axial movement ndi 26 degree angular deflection. Mng'oma wake mulibe zingwe zopingasa mozungulira monga mitundu ina yambiri ya zingwe, koma nthawi zambiri amakhala wotsika mtengo komanso wogwira ntchito bwino. Chifukwa chake, imagwiritsidwa ntchito popanga magudumu akumbuyo kapena mkati mwa magalimoto oyendetsa kutsogolo komwe mayendedwe ofunikira ndi ochepa.

Zambiri pa mutuwo:
  Kodi magalimoto azaka zambiri ku Europe ndi ati?

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).
