Mabuleki a wheel wheel, omwe ndi malo olumikizirana onse, ndi omwe amalola makinawo kusintha mphamvu ya makinawo, kuti asinthe malo omwe akupita, ndi makina oyendetsa magalimoto a zida zolumikizirana za "joint" za chipangizo cholumikizirana. Kuphatikiza kwa mabuleki a wheel wheel ndi shaft yoyendetsa, komwe kumadziwika kuti chipangizo cholumikizirana cha Universal joint. Chipangizo cholumikizira mabuleki a wheel wheel nthawi zambiri chimakhala ndi malo olumikizirana ndi ma shaft oyendetsera, ndipo nthawi zina chothandizira chapakati, chomwe chimagwiritsidwa ntchito makamaka m'malo ena otsatirawa: malo olumikizirana 1-universal; ma shaft oyendetsera awiri; shaft yoyendetsera kutsogolo kwa 3; chithandizo chapakati cha 4. Pakugwirizana kwa malo olumikizirana onse, kuzungulira kwa gawo limodzi (shaft yotulutsa) kuzungulira shaft yake kumayendetsedwa ndi kuzungulira kwa gawo lina la Universal (shaft yolowetsa) kuzungulira shaft yake.
Kuletsa mawilo a Universal wheel molunjika ku torsion kaya pali kusinthasintha koonekeratu kungagawidwe m'magulu olimba a Universal ndi ma Universal Joints osinthasintha. Ma Universal Joints okhwima angagawidwe m'magulu osagwirizana a Universal speed (omwe amagwiritsidwa ntchito kwambiri pamtundu wa cross shaft), ma Universal Joints othamanga mofanana (monga ma duplex Universal Joints) ndi ma Universal Joints othamanga mofanana (monga ma ball-cage type Universal Joints) atatu. Ma Universal Joints momwe ngodya pakati pa ma shafts awiri olumikizidwa ndi brake ya Universal ndi yayikulu kuposa zero, ndipo ma output ndi input shafts amasamutsa kayendedwe ndi variable instantaneous angular velocity ratio, koma avereji angular velocities ndi ofanana.
Ma cross-axis type rigid Universal joint joint fork, cross shaft, needle roller bearing, oil seal, set of simple, bearing cover and other components. Mfundo yogwirira ntchito ndi iyi: imodzi mwa ma fork ozungulira imayendetsa foloko inayo kuti izungulire kudzera mu cross shaft, ndipo nthawi yomweyo, imatha kuzungulira pakati pa cross shaft mbali iliyonse. Panthawi yozungulira, ma needle rollers mu needle bearings amatha kuzungulira kuti achepetse kukangana. Shaft yolumikizidwa ndi mphamvu yolowera imatchedwa input shaft (yomwe imatchedwanso active shaft), ndipo shaft output by the universal joint imatchedwa output shaft (yomwe imatchedwanso drived shaft). Universal brake imagwira ntchito pansi pa mikhalidwe yomwe pali ngodya pakati pa input ndi output shafts, komwe angular velocities ya ma shafts awiriwa ndi osagwirizana, ndipo chifukwa chake ingayambitse torsional vibration ya output shaft ndi transmission components yolumikizidwa nayo ndikukhudza moyo wa zigawozo. Imatanthauza Universal brake yomwe imatumiza kuyenda pa liwiro lofanana la angular pa ngodya yopangidwira komanso pa liwiro lofanana la angular pa ngodya zina. Yagawidwa m'magulu awa:
(a) Ma joint amitundu iwiri okhala ndi liwiro lofanana ndi la Duplex. Amatanthauza joint yamitundu yonse yomwe kutalika kwa shaft yoyendetsera mu joint yamitundu yonse yolumikizira liwiro lofanana kumafupikitsidwa kukhala kochepa.
b) Ma bump type quasi-isochronous Universal joints. Ndi ma bump joints awiri ndi mawonekedwe awiri osiyana a bump composition. Ma bumps awiriwa ndi ofanana ndi intermediate drive shaft ndi ma cross pin awiri mu duplex Universal joint device.
(c) Ma connection amitundu yonse okhala ndi ma pin atatu omwe ali ndi ma quasi-isochronous. Amapangidwa ndi ma shaft awiri okhala ndi ma pin atatu, foloko yogwira ntchito ya eccentric shaft ndi foloko yogwira ntchito ya eccentric shaft.
(d) Cholumikizira cha mtundu wa Spherical roller quasi-isokinetic Universal. Chimapangidwa ndi pin shaft, spherical roller, universal joint shaft ndi silinda. Cholumikiziracho chimatha kuyenda mozungulira mu groove, kuchita gawo la expansion spline. Kulumikizana kwa roll ndi groove pakhoma kumatha kusamutsa torque. Zolumikizira za Universal momwe zotulutsa ndi zolowetsa zolumikizidwa ndi brake ya universal zimatumiza kayendedwe ka liwiro lofanana nthawi zonse.
