Mabhandi enguva
Bhandi renguva yakanaka kana bhandi redhiraivha rine nguva yainotora kupedzisa orbit imwe kutenderera pasirese muhupenyu hwayo.
Bhandi rakanaka remazino kana bhandi rekushandisa rinofamba chinhambwe chakaenzana nemhindumupindu imwe yakapoteredza Nyika muhupenyu hwayo, uye mazino ebhanhire renguva anobata kakawanda sekune vanhu munyika. Pakupera kwegumbo, bhanhire rinofanira kuchinjwa. Zvechokwadi, kana zvichidikanwa, bhanhire rinofanira kuchinjwa kare.
MuEurope moga, mabhandi enguva ane mamiriyoni 40 anotsiviwa gore rimwe nerimwe. Kune iyi nhamba inofanirwa kuwedzerwa mabhandi ekutyaira (akadai seMulti-V) anowanikwa mumotokari yega yega. Mabhanhire chikamu chehurongwa hwemapulleys, tensioners, seals uye pombi dzemvura izvo muzviitiko zvakawanda zvinoda kuchinjwa panguva imwe chete.
Bhandi renguva inzira yakanyarara uye isina vibration yekuwiriranisa mavharuvhu neimwe injini. Ikozvino yakakosha kune injini kupfuura nakare kose. Inenge imwe neimwe injini itsva ine kudhumhana umo mavharuvhu nemapistoni ari pedyo pamwe chete. Bhandi rakatsemuka kana kuputsika renguva rinogona kuita kuti piston irove vharafu yakashama, zvichiita kuti mavharuvhu akotama, mapistoni aputika, zvokonzera kukuvara kwakanyanya kweinjini.
Kunyange kana injini dzisina kudhumhana dzisingakuvadzi kusvika pamwero wakafanana neinjini dzisina kudhumhana, kana pakaitika kukundikana kwebhandi renguva, mutyairi anozoguma ari padivi neinjini yakakundikana. Nhasi, bhanhire renguva chikamu chakakosha chegasi rekugovera hurongwa, pamwe chete nejekiseni nemapombi emvura.
Bhandi reMulti-V uye bhandi rekushandisa dhiraivha ndizvo zvakajairwa pamotokari dzakagadzirwa kubva mukupera kwamakumi mapfumbamwe. Vanopa kuvimbika kukuru uye hukuru hwekuremerwa kwepamusoro kupfuura yekare mabhandi eV. Nekuuya kwekugadzirisa simba uye air conditioning, mabhandi akawanda eV akave akakosha pakushanda kwekushandisa. Pamotokari ine bhandi reMulti-V rakakanganisika, alternator inogona kukuvadzwa, simba rekufambisa rinogona kurasikirwa, uye mumatambudziko akaipisisa, bhanhire rinogona kupinda muhurongwa hwekugadzirisa nguva.
Bhandi kana cheni?
Kubva pakaunzwa bhandi renguva, basa rayo rakashanduka nekuda kwekuvandudzwa kwezvinhu zvitsva uye maumbirwo emazino anogona kumira tembiricha yepamusoro uye simba rakawanda reinjini. Imwe neimwe injini modhi kazhinji ine yayo bhandi modhi. Mumakumi emakore achangopfuura, vagadziri vemotokari vazhinji muEurope vakasarudza mabhandi enguva. Asi maketani enguva ari kudzoka, uye iye zvino anowanikwa mu20% kusvika ku50% yeinjini dzekupedzisira dzakagadzirwa nemakambani emotokari.
“Zvichida vagadziri vacho vaive nedambudziko nemamwe mabhandi ekare uye cheni dzinotora nzvimbo shoma pamberi peinjini. Zvakadaro, kutsiva cheni yenguva netiming chain kazhinji kunoda kubviswa kweinjini nemberi kweinjini yese, izvo zvinoda nguva nemari yakawanda kubva pakuona kwemutengi,” akadaro Maurice Foote, SKF Engine Manager. Kunyangwe iyo Multi-V tambo yave yakajairika, hapana akajairwa tambo. Panogona kunge paine mashoma mashoma mabhandi ekutyaira ehurefu hwakasiyana kune yega injini modhi. Zvinoenderana nemidziyo yakaiswa pamotokari. Kureba kwetambo kwakakosha zvikuru - kunyange millimeters inotorwa munhoroondo pano. Ngatitii yepakutanga Multi-V bhandi motokari ane kureba 1691 millimeters. Vamwe vatengesi vanogona kupa tambo ipfupi se1688mm, vachiti ndiyo yakaringana kureba kune yako mota modhi. Nekudaro, iwo matatu mamirimita akashaikwa anogona kukonzera kuzunguzika kwakanyanya kana ruzha uye kutsvedza kana mutambo usiri mukati meiyo inobvumidzwa renji ye auto tensioner.
Multi V-mabhandi
Iyo Multi-V bhandi inoshanda munzvimbo dzakaoma. Inowanzoonekwa kune tsvina, mvura nemafuta, uye zviri nani zvakagadzirirwa motokari, kunyanya kunetseka pabhanhire kunowedzera.
Kuvandudzwa kweaerodynamic kuita kwemota kunoreva kushomeka kwemhepo uye tembiricha inodziya pasi pehodhi, kana sezvaungataura, yakawanda injini munzvimbo shoma. Injini dzine simba rakawanda dzinomhanya patembiricha yepamusoro hadziite kuti basa rive nyore. Izvi ndezvechokwadi kunyanya kune bhandi renguva. Mishonga miviri inoreva mabhanhire akareba, uye dhayamita yemapulleys ari kuwedzera maduku uye maduku, kuchengetedza nzvimbo. Uye, chokwadi, zvikamu zvose zvinofanira kuyera zvishoma sezvinobvira.
Hupenyu hwesevhisi hwakakurudzirwa hwemabhandi enguva nhasi anowanzo 60 makore. kusvika zviuru makumi manomwe zvemakiromita. Mabhandi akasimba zvakakwana kuti amire torques, zvakare nekuda kwekuwedzera fiberglass kusimbiswa. Hupenyu hwesevhisi yebhandi system inogara ichiyerwa mumakiromita anofambiswa. Ichi ndicho chinhu chikuru, asi kwete chete. Kune mamwe mashoma anogona kupfupisa hupenyu hwebhanhire - maviri anotevera akanyanya kusimba kana akanyanya kusununguka tension. Yokutanga inokonzera kupfeka uye kusvetuka kwemeno, uye yechipiri inokonzera kupera uye kukanganisa kune rumwe rutivi rwebhanhire, izvo zvinotungamirira kuwedzera kupfeka pama rollers uye mabheya. Vibration, oiri, mafuta kana kudonha kwemvura, uye ngura ndezvimwe zvinhu zvinogona kupfupisa hupenyu hwemasisitimu ako.
