Universal vhiri brake kureva, majoini epasirese, ndeyekuona iyo inochinja angle simba rekufambisa kwemuchina, nekuda kwekuchinja chinzvimbo chegwaro redhiraivha shaft mutsara, ndiyo yemotokari dhiraivha system yeiyo universal transmission mudziyo "joint. ” zvikamu. Universal vhiri mabhureki uye dhiraivha shaft musanganiswa, inozivikanwa seyepasirese yakabatana yekufambisa mudziyo. Universal vhiri mabhureki kutapurirana mudziyo unowanzo kuumbwa majoini epasi rose uye dhiraivha shafts, uye dzimwe nguva tsigiro yepakati, inonyanya kushandiswa mune dzimwe dzezvinzvimbo zvinotevera: 1-universal joints; 2-kutyaira shafts; 3-kumberi drive shaft; 4-yepakati rutsigiro. Mukubatana kwepasi rose, kutenderera kwechimwe chikamu (shaft yekubuda) kutenderedza shaft yayo pachayo kunofambiswa nekutenderera kwechimwe chikamu chejoini yepasi rose (shaft yekupinza) kutenderedza shaft yayo.
Universal vhiri braking munzira ye torsion kunyangwe paine elasticity iri pachena inogona kukamurwa kuita majoini akaomarara epasirese uye anochinjika majoini epasirese. Majoini akaomesesa epasirese anogona kupatsanurwa kuita asina kuenzana kumhanya kwepasirese majoini (anowanzo shandiswa kuchinjika shaft rudzi), quasi-yakaenzana kumhanya universal majoini (senge duplex universal joints) uye yakaenzana kumhanya yepasirese majoini (senge bhora-keji mhando universal joints) matatu . Majoini epasirese umo kona iri pakati pemashaft maviri akabatana nepasirese brake yakakura kupfuura zero, uye inobuda uye yekupinza shafts inotamisa mafambiro ane inosiyana instantaneous angular velocity ratio, asi avhareji angular velocities akaenzana.
Cross-axis type rigid universal joints inoumbwa neuniversal joint fork, cross shaft, tsono roller bearing, chisimbiso chemafuta, set of simple, covering cover nezvimwe zvinhu. Nheyo yekushanda ndeyotevera: imwe yeforogo inotenderera inotyaira imwe forogo kuti itenderere nemuchinjiko shaft, uye panguva imwecheteyo, inogona kutenderera ichitenderedza nechepakati chemuchinjikwa shaft mune chero nzira. Panguva yekutenderedza, tsono dzinomonereka mumabhengi etsono dzinogona kutenderera kuderedza kukwenya. Iyo shaft yakabatana kune simba rekupinza inonzi shaft yekupinza (inonziwo shaft inoshanda), uye shaft inobuda nejoint yepasi rose inonzi inobuda shaft (inodaidzwawo kuti driven shaft). Brake yepasirese inoshanda pasi pemamiriro ekuti kune kona pakati peiyo yekupinza uye yekubuda shaft, uko angular velocities emashaft maviri asina kuenzana, uye semhedzisiro inogona kukonzera torsional vibration yeyakabuda shaft uye zvinhu zvekufambisa zvakabatanidzwa nazvo uye zvinokanganisa. hupenyu hwezvikamu izvozvo. Zvinoreva bhureki repasirese rinofambisa kufamba kwakaenzana pakarepo angular velocities pakona yakagadzirwa uye painoda kuenzana instantineous angular velocities kune mamwe makona. Yakakamurwa kuva:
(a) Duplex mhando quasi-yakaenzana kumhanya universal joints. Inoreva mubatanidzwa wepasirese umo kureba kwedhiraivha shaft mumubatanidzwa wepasirese yakaenzana kumhanya dhiraivha kunopfupikiswa kusvika padiki.
b) Bump type quasi-isochronous universal joints. Nemajoini maviri epasi rose uye maviri akasiyana maumbirwo e bump composition. Iwo mabumps maviri akaenzana nepakati dhiraivha shaft uye mapini maviri emuchinjikwa mune duplex universal joint device.
(c) Matatu-pini mhando quasi-isochronous universal joints. Iyo ine maviri matatu-pini shafts, inoshanda eccentric shaft fork uye inofambiswa eccentric shaft fork.
(d) Spherical roller type quasi-isokinetic universal joint. Iyo ine pini shaft, spherical roller, universal joint shaft uye silinda. Iyo roller inogona kufamba axially mu groove, ichitamba basa rekuwedzera spline. Roller uye groove madziro kusangana anogona kutamisa torque. Majoini epasirese maainoburitsa uye mashaft ekuisa akabatana neapasirose brake anofambisa mafambiro nguva dzose akaenzana instantaneous angular velocities.
