Universal wheel brake, ndiye kuti, maulalo onse, ndikuzindikira kusinthasintha kwamphamvu kwa makina, chifukwa chofuna kusintha komwe akulowera mzere wa shaft, ndiye makina oyendetsa magalimoto a chipangizo chapadziko lonse lapansi "cholumikizana". ” zigawo. Universal wheel brake and drive shaft kuphatikiza, yotchedwa universal joint transmission device. Chida cha Universal wheel brake transmission nthawi zambiri chimakhala ndi zolumikizira zapadziko lonse lapansi ndi ma shafts oyendetsa, ndipo nthawi zina chithandizo chapakati, chomwe chimagwiritsidwa ntchito kwambiri m'malo otsatirawa: 1-universal joints; 2-drive shafts; 3-kutsogolo shaft; 4-thandizo lapakati. Pakulumikizana kwapadziko lonse, kuzungulira kwa chigawo chimodzi (tsinde lotulutsa) kuzungulira kutsinde kwake kumayendetsedwa ndi kuzungulira kwa gawo lina la chilengedwe chonse (tsinde lolowetsa) kuzungulira kutsinde kwake.
Universal gudumu braking molunjika ku torsion ngati pali elasticity zodziwikiratu akhoza kugawidwa mu olimba konsekonse mfundo ndi kusintha konsekonse mfundo. Malumikizidwe olimba a universal amatha kugawidwa m'malo olumikizana omwe amathamanga kwambiri (omwe amagwiritsidwa ntchito pamtundu wa shaft), quasi-equal speed universal joints (monga duplex universal joints) ndi liwiro lofanana lolumikizana konsekonse (monga mpira-cage mtundu wa universal joints) atatu. . Malunjidwe achilengedwe chonse momwe ngodya yapakati pa ma shaft awiri olumikizidwa ndi brake yapadziko lonse lapansi ndi yayikulu kuposa ziro, ndipo zotulutsa ndi zolowetsa shafts zimasuntha ndikusintha pompopompo chiŵerengero champhamvu ya angular velocity, koma ma velocities ang'ono ndi ofanana.
Malumikizidwe olimba amtundu wa Cross-axis amapangidwa ndi foloko yapadziko lonse lapansi, shaft yolumikizira singano, chisindikizo chamafuta, chosavuta, chivundikiro ndi zinthu zina. Mfundo yogwirira ntchito ili motere: imodzi mwa mafoloko ozungulira imayendetsa mphanda wina kuti uzungulire kudutsa pamtanda, ndipo nthawi yomweyo, imatha kuzungulira pakati pa mtandawo kumbali iliyonse. Panthawi yozungulira, zodzigudubuza za singano zomwe zili mu singano zimatha kuzungulira kuti zichepetse kukangana. Shaft yolumikizidwa ndi mphamvu yolowera imatchedwa shaft yolowera (yomwe imatchedwanso shaft yogwira), ndipo shaft yomwe imatuluka pagulu lapadziko lonse lapansi imatchedwa shaft yotulutsa (yomwe imatchedwanso shaft yoyendetsedwa). Kuphulika kwapadziko lonse kumagwira ntchito pansi pazikhalidwe zomwe pali ngodya pakati pa zolowetsa ndi zotulutsa, kumene mayendedwe aang'ono a mapiko awiriwo ndi osafanana, ndipo chifukwa chake angayambitse kugwedezeka kwa torsional shaft ndi zigawo zotumizira zomwe zimagwirizanitsidwa ndi izo ndikukhudza. moyo wa zigawo zimenezo. Amatanthawuza mabuleki oyenda padziko lonse lapansi omwe amasuntha ma velocities ofanana pompopompo ang'ono pa ngodya yopangidwa komanso pafupifupi ofanana ma liwiro ang'ono pompopompo pamakona ena. Amagawidwa kukhala:
(a) Mtundu wa Duplex quasi-equal speed universal joints. Zimatanthawuza kulumikiza kwapadziko lonse komwe kutalika kwa shaft yoyendetsa mumtunda wapadziko lonse wofanana ndi liwiro kumafupikitsidwa mpaka pang'ono.
b) Mtundu wa bump quasi-isochronous universal joints. Pamagulu awiri a chilengedwe chonse ndi mawonekedwe awiri osiyana a bump. Mabampu awiriwa ndi ofanana ndi shaft yapakatikati ndi mapini awiri opingasa paduplex universal joint joint.
(c) Mapini atatu amtundu wa quasi-isochronous universal joints. Imakhala ndi mapini awiri apini atatu, foloko yokhazikika ya shaft ndi foloko ya eccentric shaft.
(d) Mtundu wozungulira wa quasi-isokinetic universal joint. Zimapangidwa ndi pin shaft, spherical roller, universal joint shaft ndi silinda. Wodzigudubuza amatha kusuntha axially mu poyambira, kusewera gawo la spline yowonjezera. Roller ndi groove khoma kulumikizana kumatha kusamutsa torque. Malunji a Universal momwe zotulutsa ndi zolowetsa zolumikizidwa ndi mabuleki apadziko lonse zimasuntha nthawi zonse ma liwiro aang'ono pompopompo.
