Motokari dzakawanda dzemazuva ano dzine mavhiri dzinoshandisa power steering, iyo inobva papombi inofambiswa nebhandi.Verenga pamusoro pekuti bhanhire rinotungamirira chii, ndeapi marudzi emabhanhire aripo uye kuti akarongwa sei, pamwe chete nekusarudzwa uye kuchinjwa kwezvikamu izvi munyaya.
Chii chinonzi bhandi rekutungamirira simba?
Simba rekutungamirira bhanhire (simba rinotungamirira bhandi, simba rekufambisa bhandi) - chinhu chesimba rekutungamirira hurongwa hwemotokari dzine mavhiri;bhanhire risingagumi (rakavharwa) nenzira iyo pombi yekufambisa mafuta inotungamirirwa kubva injini crankshaft pulley kana imwe yakasungirirwa unit.
Mota zhinji dzemazuvano dzakashongedzerwa nemagetsi chidhiraivho (simba chidhiraivho), izvo zvinogadzira imwe torque pamavhiri anofambisa kufambisa kutyaira.Simba rinodiwa pamagetsi ekufambisa simba rinogadzirwa nekumanikidzwa kwemvura inoshanda inobva kune imwe pombi.Sezvo mutemo, pombi yekutungamirira simba, pamwe chete nemamwe mayuniti, inoiswa zvakananga pamagetsi emagetsi, uye motokari yaro inovakwa maererano nechirongwa chekare - uchishandisa V-belt transmission kubva kune crankshaft pulley kana imwe yakakwira unit.
Hwaro hweiyo V-bhandi kutapurirana isimba rekutungamira bhandi, iro rinogadzirisa basa rimwechete rakakosha - kuve nechokwadi chekutapurirana kwe torque kubva ku crankshaft pulley kana imwe unit kune simba rinotungamira pombi pulley mune yese injini yekumhanyisa renji (kusanganisira yenguva pfupi modes) uye mune chero mamiriro ekushanda.Iri bhanhire, zvichienderana nerudzi rwemagetsi ekufambisa, rinoita basa guru kana rakaderera mukuvimbisa kushanda kwejini uye kubata kwemotokari, asi chero ipi zvayo, kana yakasakara kana kukuvara, inofanira kuchinjwa kuva itsva. pasina kunonoka kusiri madikanwa.Uye usati watenga bhandi idzva rekutungamirira simba, unofanirwa kunzwisisa marudzi aripo ezvikamu izvi, maitiro avo uye maitiro.
Mhando, mudziyo uye maitiro emabhandi ekutungamirira simba
Iyo dhiraivha yepombi inotungamira simba inogona kuvakwa zvinoenderana neakasiyana zvirongwa:
● Nekubatsirwa kwebhanhire rinowanzoita motokari yezvikamu zvakasungirirwa zvejini;
● Nekubatsirwa kwebhanhire rega rega kubva kune injini crankshaft pulley;
● Nekubatsirwa kwebhanhire rega rega kubva kune pulley yeimwe yakasungirirwa unit - pombi yemvura kana jenereta.
Muchiitiko chekutanga, pombi yekufambisa simba inosanganiswa mune imwe motokari yezvikwata zvakasungirirwa nebhanhire rakafanana, mushanduro iri nyore, bhanhire rinovhara jenereta uye pombi yemvura, pamabhazi nemarori, pombi yekutungamirira simba inogona kuva common drive ine air compressor;Mune zvimwe zvakaoma zvirongwa, iyo air conditioning compressor uye mamwe mayuniti anosanganisirwa mudhiraivha.Muchiitiko chechipiri, bhandi rakasiyana rakasiyana rinoshandiswa, iro rinotumira torque zvakananga kubva ku crankshaft pulley kuenda kune simba rinotungamirira pombi pulley.Muchiitiko chechitatu, torque inotanga kupiwa pombi yemvura kana jenereta ine pulley kaviri, uye kubva pazvikamu izvi kuburikidza nebhanhire rakasiyana kune simba rinotungamirira pombi.

Dhiraivha pombi yekutungamirira magetsi nebhandi rayo rine tensioner
Kutyaira pombi yekutungamirira simba, mabhandi emhando dzakasiyana siyana uye saizi anoshandiswa:
● Smooth V-mabhandi;
● Toothed V-mabhandi;
● V-ribbed (multi-stranded) mabhandi.
V-bhandi rakatsetseka ndicho chigadzirwa chakareruka chinoshandiswa zvakanyanya mumotokari dzepamba nemabhazi.Bhandi rakadaro rine trapezoidal cross-section, mupendero wayo wakamanikana wakadzikama, wakafara - radius (convex), iyo inovimbisa kugovaniswa kwemasimba mukati mebhandi kana yakakotama.
A mazino V-bhanhire ndiro rimwe chete V-bhandi umo transverse notches (mazino) anogadzirwa pachigadziko chakamanikana, kuwedzera kushanduka kwechigadzirwa pasina kurasikirwa kwesimba.Mabhanhire akadaro anogona kushandiswa pamapulleys ediki dhayamita uye anoshanda kazhinji mumhando dzakasiyana dzekushisa.
Bhandi reV-ribbed ndiro bhanhire rakati sandara uye rakafara, pamusoro pebasa rekushanda iro kune kubva pamatatu kusvika kune manomwe akareba V-grooves (hova).Bhandi rakadaro rine nzvimbo yakakura yekubatana nemapulleys, iyo inovimbisa kuvimbika kwekutengesa torque uye inoderedza mukana wekutsvedza.

Simba rinotungamira V-bhandi renguva bhandi
V-ribbed simba rekufambisa bhandi
Mabhandi eV anotsvedzerera uye ane mazino anoshandiswa mumadhiraivha ega ega epombi yekumhanyisa simba kubva ku crankshaft uye mumadhiraivha epombi akasanganiswa nedhiraivha yemhepo compressor kana imwe unit.Madhiraivha pahwaro hweV-mabhandi anonyanya kushandiswa pamidziyo yemumba, pamwe nemabhazi uye mota dzekutengesa dzekugadzirwa kweAsia.Mabhandi e-V-ribbed ane nhamba huru yehova (6-7) anonyanya kushandiswa mumadhiraivha akaiswa mayuniti emagetsi emagetsi, kazhinji mabhandi edhizaini iyi, asi ane nhamba diki yehova (chete 2-4). ), anowanikwa mumadhiraivha ega ega emagetsi anotungamira pombi kubva kune crankshaft kana imwe yakakwira unit.Madhiraivha ane V-ribbed mabhandi anowanzo shandiswa mumotokari dzinogadzirwa kunze kwenyika.
Mabhandi ekutungamirira ane simba ane nyore kugadzira.Nheyo yebhanhire inotakura tambo muchimiro chetambo yakagadzirwa nefiber synthetic (polyamide, polyester kana imwe), iyo iyo iyo bhanhire pachayo inoumbwa kubva kune vulcanized rubber yemhando dzakasiyana-siyana.Smooth uye serrated V-mabhandi anowanzova nekuwedzera kuchengetedzwa kwekunze kwekunze nenzira yerukwa rakagadzirwa nemucheka mutete wekuputira muzvikamu zviviri kusvika zvitatu.Kuti uone bhanhire, kucherechedzwa uye ruzivo rwakasiyana-siyana rwebetsero runogona kushandiswa pahwaro hwaro hwakafara.
Rubber V-mabhandi e hydraulic boosters emidziyo yemumba anofanirwa kuenderana neGOST 5813-2015 yakajairwa, anogona kugadzirwa mune maviri mavhezheni muhupamhi (akatetepa uye akajairwa muchinjiko-chikamu) uye ane yakajairwa chiyero chehukuru.Mabhandi e-V-ribbed anogadzirwa zvinoenderana neyakasiyana siyana zviyero uye automakers 'chawo zviyero.
Kucheka kwebhandi remagetsi ekufambisa
Nyaya dzekusarudza uye kuchinjwa kwebhanhire rekufambisa simba
Panguva yekushanda kwechikwata chemagetsi, mabhanhire ose anopera uye pakupedzisira anoda kuchinjwa, izvi zvinoshanda zvizere kune bhanhire rinotungamirira simba.Kutsiviwa kwebhanhire iri kunofanira kuitwa mukati menguva inokurudzirwa neautomaker, kana (inoitika kakawanda) kana yakasakara kana kukuvara.Kazhinji, kudiwa kwekutsiva bhanhire rekufambisa simba kunoratidzwa nekuparara kwesimba rinotungamirira mumhando dzose dzekushanda kwemotokari.Uyewo, bhanhire rinofanira kuchinjwa kana kuputika kunowanikwa pairi, kutambanudza zvakanyanya uye, zvechokwadi, kana ichiputsika.
Kutsiva, iwe unofanirwa kusarudza bhandi remhando imwechete iyo yakaiswa pamotokari kare.Pamotokari itsva, iyi inofanira kunge iri bhanhire reimwe nhamba yekodhi, uye mushure mekupera kwenguva yewaranti, unogona kushandisa chero mabhanhire ane maitiro akakodzera - rudzi (V-plate, V-ribbed), cross-section uye urefu.Kana simba rekutungamirira pombi bhandi rine tension roller, saka zvakakosha kutenga chikamu ichi pakarepo pamwe chete nemagetsi.Hazvikurudzirwi kusiya tensioner yekare, sezvo izvi zvinogona kutungamirira kukupfeka kwakanyanya kana kukanganisa kwebhanhire idzva.
Kutsiviwa kwebhanhire rekufambisa simba kunofanira kuitwa maererano nemirairo yekugadzirisa nekugadzirisa motokari.Pamamotor ane munhu anotyaira pombi yekutungamirira simba uye pasina tensioner, zvakakwana kusunungura pombi yekusungirirwa, kubvisa bhanhire rekare, kuisa rimwe idzva uye kusimbisa bhanhire nekuda kwekusungirirwa kwepombi.Kana tension roller inopiwa mumotokari yakadaro, ipapo kutanga kwezvose inobviswa, ipapo bhanhire rinobviswa, imwe itsva inoiswa panzvimbo yayo, uye ipapo tensioner itsva inoiswa.Mune injini dzine dhiraivha yakajairika yezvibatanidzwa, bhanhire rinotsiviwa nenzira imwechete.
Mune zvimwe zviitiko, basa rekutsiva bhanhire rinogona kuoma nekudiwa kwekuita mamwe mabasa.Semuenzaniso, pamainjini akawanda, unofanira kutanga wabvisa bhandi redhiraivha, wozotsiva bhandi rekutungamirira pombi.Izvi zvinofanirwa kuverengerwa uye nekukurumidza gadzirira chishandiso chakakodzera.
Chinhu chinonyanya kukosha pakutsivabhandi rekutungamirira simbandeye kuona kuti yakanyatso tension.Kana bhanhire rakanyanyisa-tensioned, zvikamu zvichasangana nemitoro yakakwirira, uye bhanhire pacharo richatambanudza uye rinopera munguva pfupi.Nekunetseka kusina simba, bhanhire richatsvedza, izvo zvichaita kuti kuparara kwekushanda kwesimba rekufambisa.Naizvozvo, zvinodikanwa kunyatsotevera kurudziro yakapihwa mumirayiridzo, uye, kana tezvara vane mukana wakadaro, shandisa chishandiso chakakosha kuti uve nechokwadi chekunetsana kwakajairika.
Nechisarudzo chakanaka uye kutsiva bhanhire, simba rekufambisa richapa kutyaira kwakasununguka mumamiriro ese emugwagwa.
