CVT gearbox

CVT gearbox - nws yog zoo li ib tug gearbox, uas muaj tsis muaj cov kauj ruam, thaum muab ib tug tus nce los yog txo nyob rau hauv cov iav ratio. Qhov no feature ntawm qhov variator tso cai rau nws siv lub hwj chim ntawm lub engine li nraaj tau, ua tsheb puab thiab txo cov roj noj. Txawm nyob rau hauv lub thib kaum tsib caug xyoo, lub legendary Leonardo da Vinci yees lub tswvyim ntawm tus variator. Txawm li cas los, thawj lub tsheb nrog xws li kis tau tus mob tuaj mus nyob xwb nyob rau hauv nruab nrab ntawm lub xeem caug xyoo. Nyob rau ntawm lub sij hawm uas nws siv los ntawm ob peb lub tsheb ua qauv, dav siv nws yog pom xwb nyob rau hauv peb lub sij hawm, thaum lub mechanics twb tau mus ua nws lub zoo meej tsim.

CVT kis tau tus mob muaj cov nram qab no hais: ib tug CVT kis tau tus mob, los ua ke, disconnecting lub cav thiab CVT, uas yog muab hauv nruab nrab txoj hauj lwm, thiab ib tug tswj system thiab ib tug mechanism rau reversing. Niaj hnub nimno tsheb khiav nrog rau kev siv ntawm ob hom CVTs: toroidal thiab ib tug V-siv. V-siv variator muaj ob Pulleys uas yog nyob rau ntawm txawv axes, thiab lawv muaj kev cob cog ntawm ib tug V-siv. Txhua pulley muaj ob tug conical disc, uas fim txhua lwm yam nrog rau lawv cov khob hliav qab vertices. Yog hais tias koj hloov qhov kev ncua deb ntawm lub discs, thiab lub lub cheeb ntawm lub pulley yog hloov. Nrog ib tug tag nrho-kev cob cog rua drives, nws yog ib txhis, thiab thaum twg tag nrho ncua - yog tsawg heev. Nws hloov tawm hais tias rau ib tug tus hloov nyob rau hauv qhov kev ncua deb ntawm txoj siv tawv discs yuav kis mus rau lub tsav pulley ntawm ib tug txawv iav ratio. Toroidal kev xaiv tsis koom nrog rau cov kev siv ntawm ib cov saw los yog siv. Nws muaj ob tug shafts uas yog cov txheej txheem ntawm nyob rau hauv thaum uas tig mus axes thiab muaj ib tug kheej kheej nto. Vim chais sandwiched ntawm lub shafts, thiab torque kis tau tus mob yog nqa tawm. Cov iav piv yog hloov los ntawm kev hloov lub synchronous haujlwm chais. Toroidal tsis tu ncua nce mus nce los kis tau tus mob no yog siv ntau tsawg heev tshaj cov V-siv. Qhov no yog vim muaj ib tug ntau ntaus ntawv.

Kis CVT: kev sib cais mechanisms

Lub cev muaj zog thiab variator yuav kaw los ntawm txoj kev ob peb hom mechanisms: ib tug electromagnetic clutch nrog ib tug hluav taws xob tswj tsis siv neeg centrifugal clutch, ib ntub dej multiplate clutch nrog rau hauv kev tswj, thiab los ntawm cov torque converter. Nws yog ib qho tseem ceeb yuav tau nco ntsoov hais tias vim cov tsim nta ntawm lub CVT yog tsis muaj peev xwm mus muab lub zog nyob rau hauv rov qab. Uas yog vim li cas lub CVT gearbox yog txawm peem rau nrog tshwj xeeb mechanisms uas yog tsim los muab ib tug reversible zog. Feem ntau qhov no luag hauj lwm yog muab rau cov planetary gearbox. Niaj hnub nimno nce mus nce los ceev drives kheev siv hluav taws xob tswj system. Lub ntsiab muaj nuj nqi ntawm lub variator tswj system yog ib tug synchronous pulley diameters hloov raws li ib tug tshwm sim ntawm cov tshuaj tiv thaiv rau cov kev hloov nyob rau hauv lub lag luam ntawm lub fais fab nroj tsuag lag luam. Hluav taws xob cov ntawm lwm yam uas thiab planetary gearbox thiab clutch.

Lub tsheb, uas yog txawm peem rau nrog ib tug CVT, zoo nkaus li tsis muaj sib txawv los ntawm lub tsheb nrog automatic kis tau tus mob. Muaj ob pedals thiab ib tug selector iav. Txawm li cas los, cov neeg tsav tsheb yuav tsum tsis meej pem los ntawm qhov tseeb hais tias muaj yog tsis muaj cov pa tsau iav, raws li zoo raws li jolts los yog slowdowns thaum switching. CVT accelerates lub tsheb confidently thiab ntseeg nkaws, uas tsis muaj jerks. Qhov no teeb meem puas hawv tau daws los ntawm niaj hnub manufacturers. Lawv qhia cov muaj peev xwm xaiv tau ntau tsau txaus ntawm iav. Qhov no yog ua li cas rau simulate ib tug classic iav. Nyob rau hauv cov ntaub ntawv no, tus neeg tsav tsheb zaum tom qab lub log lawv yuav hloov forcibly. Nws hloov tawm hais tias xws li ib tug lub thawv tsheb zoo heev iav tsis txawv los ntawm uas siv yav tas los.
