Mabhureki evhiri reUniversal, kureva kuti, majoini epasi rose, ndeekuita kuti muchina ugone kuchinja angle power transmission, kuti pave nekuchinja nzvimbo yegwara remuchina wedhiraivha, ndiyo automotive drive system ye "joint" device yedhiraivha yepasi rose. Musanganiswa webhureki revhiri repasi rose nedhiraivha yedhiraivha, inozivikanwa seyuniversal joint transmission device. Universal wheel brake transmission device inowanzo umbwa nemajoini epasi rose nemashaft edhiraivha, uye dzimwe nguva rutsigiro rwepakati, runonyanya kushandiswa mune dzimwe nzvimbo dzinotevera: 1-universal joints; 2-drive shaft; 3-front drive shaft; 4-intermediate support. Mukubatana kwejoini rese, kutenderera kwechikamu chimwe (output shaft) kutenderedza mushaft yacho kunotungamirwa nekutenderera kwechimwe chikamu chejoini rese (input shaft) kutenderedza mushaft yayo.
Kubhurika kwevhiri reUniversal munzira yekutenderera kana paine kutwasuka kwakajeka kunogona kukamurwa kuita majoini akaomarara eUniversal uye majoini anochinjika eUniversal. Majoini akaomarara eUniversal anogona kukamurwa kuita majoini asina kuenzana ekumhanya (anowanzo shandiswa kune rudzi rwe cross shaft), majoini eUniversal ane quasi-equal speed (akadai se duplex universal joints) uye majoini eUniversal ane speed yakaenzana (akadai se ball-cage type universal joints) matatu. Majoini eUniversal umo kona iri pakati pemashaft maviri akabatana nebhureki reUniversal yakakura kupfuura zero, uye output and input shafts transfer motion ine variable instantaneous angular velocity ratio, asi avhareji ye angular velocities yakaenzana.
Majoini epasi rose akasimba emhando yecross-axis anoumbwa neforogo yejoini yeuniversal, cross shaft, needle roller bearing, oil set, seti ye simple, bearing cover nezvimwe zvikamu. Nheyo yekushanda ndeiyi inotevera: imwe yemaforogo anotenderera inotyaira imwe forogo kuti itenderere nepacross shaft, uye panguva imwe chete, inogona kutenderedza pakati pecross shaft chero kupi. Munguva yekutenderera, maneedle roller ari mumaneedle bearing anogona kutenderera kuderedza kukweshana. Shaft yakabatana nesimba rekupinda inonzi input shaft (inonziwo active shaft), uye shaft output neuniversal joint inonzi output shaft (inonziwo drived shaft). Bhureki repasi rose rinoshanda mumamiriro ezvinhu apo pane angle pakati peinput ne output shafts, uko angular velocities yemashafts maviri asina kuenzana, uye nekuda kweizvozvo zvinogona kukonzera torsional vibration ye output shaft ne transmission components zvakabatana nayo uye zvinokanganisa hupenyu hwezvikamu izvozvo. Zvinoreva bhureki repasi rose rinotumira kufamba ne instantaneous angular velocities yakaenzana pa angle yakagadzirwa uye pa instantaneous angular velocities yakaenzana pamamwe makona. Yakakamurwa kuita:
(a) Majoini epasi rose emhando yeDuplex akaenzana nekumhanya. Anoreva joini yepasi rose umo kureba kweshaft yedhiraivha mujoini yepasi rose inopfupikiswa kusvika padiki.
b) Majoini emhando yebump quasi-isochronous universal. Nemajoini maviri euniversal uye maumbirwo maviri akasiyana emuumbirwo webump. Majoini maviri aya akaenzana neintermediate drive shaft uye mapini maviri ecross pin mu duplex universal joint device.
(c) Majoini epasi rose ane mapini matatu akaenzana neasingaonekwe. Ane mashaft maviri ane mapini matatu, forogo yeshaft inoshanda uye forogo yeshaft inofambiswa.
(d) Spherical roller type quasi-isokinetic universal joint. Inosanganisira pin shaft, spherical roller, universal joint shaft uye cylinder. Roller inogona kufamba ne axially mu groove, ichitamba basa re expansion spline. Roller ne groove wall contact zvinogona kutamisa torque. Universal joints umo output ne input shafts zvakabatana ne universal brake transmit motion panguva imwe chete yakaenzana.
