CVT kutapurirana - zvakanakira uye zvakaipira zvegiya bhokisi uye variator mumotokari

Iyo CVT kuendesa kune akasiyana mazita ekutengesa, akadai seMultitronic yemhando yeAudi. Kusiyana neyakajairwa otomatiki mhinduro, nhamba yegiya pano ndeye - theoretically - isingaperi, saka, hapana nhanho dzepakati (kune hushoma uye hwakanyanya). Dzidza zvakawanda nezve CVT kutapurirana!

Variator inoshanda sei? Chii chinoita kuti zvioneke?

Kutenda kune yakanyatso gadzirwa CVT kufambisa, simba remotokari yemagetsi unit rinoshandiswa zvakanyanya. Izvi zvinokonzerwa nekuti inosarudza otomatiki reshiyo yegiya kuitira kuti ichengetedze kumhanya kweinjini padanho rakakodzera. Panguva yekutyaira kwakajairika iyi inogona kunge iri 2000 rpm, asi kana ichimhanyisa inogona kukwira kusvika pamwero wekuti injini inosvika pakureba kwayo torque. Zvinokosha kucherechedza kuti michina yakanakira zvose peturu uye diesel mafuta, uye kunyange hybrid motokari.

Dhizaini uye kushanda kweCVT inoramba ichichinja kutapurirana

Chimwe chezvinhu zvikuru pane dhizaini uye mashandiro ega ega emazuva ano CVT kutapurirana kwakavakirwa peya yebevel giya (kubuda uye clutch), inonzi CVT. Iyo yakaoma chimiro zvakare ine dhiraivha yekufambisa michina kuburikidza neinorema basa resimbi bhandi. Iketani yemazana akati wandei. Ivo vanonyatso kusarudzirwa ukobvu, hupamhi uye kunyange taper angle. Nekudaro, zvigadziriso zvehunyanzvi zvehunyanzvi hazvigone kushanda zvakajairika pasina kutora chikamu kwemagetsi.

Chinhu chepakati chinosarudza maparamita anoshandiswa nemotokari isina nhanho variator ndeye yakakosha otomatiki transmission control unit. Inotarisa nzvimbo ye accelerator pedal pamwe nekumhanya kwemotokari uye inogara ichimhanya yedhiraivha unit. Pahwaro uhwu, inodzora kufamba kweiyo variator nekufambisa mavhiri ebevel pedyo kana kure kure. Nekudaro, inoshandura dhayamita yavo yekushanda uye saka inoshandura giya reshiyo rinoshandiswa parizvino. Iyo michina inoshanda zvakafanana kune bhasikoro derailleur, asi mune iyi kesi, isu hatina zvirambidzo zvepakati magiya muchimiro chegiya.

Iko kushandiswa kweanoramba achichinjika transmissions mumotokari dzemazuva ano.

Nekuda kweiyo chaiyo yekushanda kwevariator, otomatiki gearbox kuenderera mberi kuchinjika kutapurirana kunonyanya kushandiswa mumotokari dzemazuvano dzine diki diki uye, maererano, yakaderera curb huremu. Sezvo mutemo, vane injini dzine simba shoma uye yakaderera torque. Nekuda kweizvi, mabhanhire kana maketani anoendesa dhiraivha haasi pasi pemitoro yakawandisa, iyo inobvumidza iwe kugadzira yakavimbika nzira dzekufambisa. Mota dzakashongedzerwa neinjini masisitimu ane torque inosvika 200 Nm dzinoonekwa sedzakanyanya pano.

CVT kutapurirana mumotokari dze4 × 4

Innovative CVT transmissions inowanikwawo mumotokari huru 4 × 4, sezvinoratidzwa nemhando dzakagadzirwa neJapan Mitsubishi brand. Mainjiniya vane hunyanzvi vakaagadzira kusvika paakanakira mota dzinoenzana muhukuru nemota hombe kana marori. Mhinduro dzekirasi iyi dzinoshandiswawo mumotokari dzine mavhiri maviri, semuenzaniso. midhudhudhu. Yekutanga scooter ine rudzi urwu rwegiya bhokisi yakaonekwa pamusika kutanga kwa1938. 

Benefits yeCVT

Imwe yemabhenefiti makuru ekutapurirana kweCVT kugona kuderedza kushandiswa kwemafuta. Iwe uchaona kuchengetedza, kunyanya kana iwe ukatevera mitemo yekutyaira kwehupfumi uye kutarisira mamiriro ezvinhu mumugwagwa. Ehezve, kushandiswa kwakasimba kweiyo accelerator pedal kuchakanganisa kushandiswa kwemafuta, zvisinei nekuti mota ine otomatiki kana bhuku rekufambisa. Imwe bhenefiti kugona kudzikisa mutengo wekushandisa mumotokari dzakashongedzerwa neakakwira torque injini, i.e. mumadhiziri.

Rubatsiro rwunowanzotaurwa rwauchaona kana uchityaira uchitenderedza dhorobha ndiko kufamba kwakatsetseka uye nekukurumidza kudzoka nekudzoka kunochinja munzira. 

Kuipa kwebhokisi revariator 

Izvo zvisingabatsiri zvinosanganisira kushanda zvishoma kune ruzha rweiyo isina nhanho variator kana ichienzaniswa neyakajairwa muchina. Izvi zvinokonzerwawo neruzha rwunouya kubva mukamuri yeinjini, yakagadzirwa nedhiraivha (kunyangwe kumhanya kwekufamba kunenge kunogara). Vazhinji vatyairi vanoteererawo kuwanda kwekutadza kwegiya bhokisi, asi kazhinji haisi mhedzisiro yedhizaini pachayo, asi yekushanda zvisina kunaka uye kugadzirisa.

Izvo zvinowanzoitika kusashanda kweiyo vhezheni yekumhanyisa otomatiki kutapurirana (e-CVT)

Imwe yezvikanganiso zvakajairika muCVT otomatiki transmissions ndeye yakawandisa dhiraivha bhandi (kana cheni) kupfeka. Mavhiri anogadzira iyo CVT system, inova chinhu chinonyanya kukosha chekuenderera kuchinjika kuchinjika, zvakare ari pasi pekupfeka zvishoma nezvishoma.

Iko kukurumidza kuitika kwekukundikana kunonyanya kukanganiswa nekushandisa zvakanyanya sisitimu, i.e. simba, kutyaira kwemitambo kana kukurumidza kumhanyisa. Nechikonzero ichi, mota ine CVT kutapurirana haifanirwe kushandiswa pakumhanya kana mujaho wemumugwagwa. Izvo zvakakoshawo kuti uchinje mafuta egiya nguva dzose, sezvo mafuta anodzokororwa anowedzera masimba ekukwesha mukati meiyo otomatiki kutapurirana, uye nekudaro, nekukurumidza kupfeka kwayo. Izvo zvakakosha kucherechedza kuti mazhinji ematambudziko akabviswa mumichina yazvino yakanyorwa e-CVT inoshandiswa mumotokari dzakasanganiswa.

Mutengo wekushanda uye kugadzirisa kwevariator

Kudhura kwekushandisa uye kugadzirisa Variable kumhanya magiya mabhokisi ndiyo imwe yeanowanzo nharo kupokana nerudzi urwu rwesarudzo. Unofanira kugamuchira nharo dzavo here? Hazvirevi hazvo, nekuti kazhinji matambudziko anomuka nekuda kwekusashanda zvakanaka kweiyo transmission unit, uye panguva imwe chete kugadziridzwa kwemotokari nemakanika asina kusimbiswa. Mhedzisiro yeiyi nzira inodhura masevhisi, ayo akabatanidzwawo nemutengo wakakosha wezvisara.

Ziva kuti maCVT aya anowanzo kusimba zvishoma pane akajairwa otomatiki madhizaini anoshandiswa mumagadzirirwo azvino. Pfuti dzinozvifambisa zvakavanzika. Nekudaro, ivo vanopa kukwira kwakapfava uye kukurumidza, uye panguva imwechete inoratidzirwa nekushomeka kwemafuta ekushandisa uchichengetedza misimboti ye "eco driving". Chikamu chavo chinosungirwa ndeye yakakosha yemagetsi controller, iyo inogona kutadza nekuda kwehunyoro hunopinda muhurongwa kana simba rekuwedzera rine chekuita nekubatanidza rectifier kubhadharisa bhatiri.

Inoshanda uye inoshanda CVT gearbox

Inokurudzirwa nevakawanda vane ruzivo makanika uye varidzi vegaraji, iyo inoshanda uye inoshanda CVT kufambisa isarudzo yakanaka kune vanhu vazhinji. Zvakanakira zvaro zvichanyanya kufarirwa nevashandisi vemotokari, kunyanya kufamba-famba muguta. Nekugadzirisa kwakakodzera, iyo inoramba ichichinja otomatiki kutapurirana ine hupenyu hurefu hwesevhisi uye isina matambudziko kushanda.
