DSG gearbox - chii ichocho? Zvipupuriro uye mavhidhiyo
Isu takatobhadhara zvakanyanya kutarisisa pane yedu portal kune akasiyana marudzi ekufambisa kwemota. Varidzi veVolkswagen, Skoda, Seat mota mune tsananguro yehunyanzvi yemotokari dzavo mukoramu yekutumira vanogona kuona chidimbu cheDSG. Mavara echiLatin aya anorevei? Ngatiedzei kuzvinzwisisa.
Iyo robhoti yekufambisa inosiyana kubva kune yakajairwa mechanics uye kubva otomatiki kutapurirana nekuvapo kwekaviri clutch. Nekuda kweichi dhizaini chimiro, kuchinjika kwakapfava kweyekumhanyisa marenji pasina jerk uye kunonoka kunovimbiswa. Zvakanaka, irobhoti nekuti iyo yemagetsi control unit ine basa rekuchinja magiya, zvichiteerana, mutyairi ane mukana wekuchinja kune zvese otomatiki uye manyore control.
Mumashoko akareruka, iyo DSG kutapurirana ndeye yakabudirira hybrid yemanyorero uye otomatiki transmissions. Asi zvakadaro, musiyano wayo mukuru ndeye kaviri clutch.
Chigadzirwa chebhokisi ndeichi:
- dual-massive crankshaft flywheel - inopa yunifomu yekufambisa torque kune ese clutch discs, ine yekutanga uye yechipiri discs, nepo yakajairika flywheel ine monolithic chimiro;
- maviri clutch discs - kune akaenzana uye asinganzwisisike magiya;
- maviri ekutanga uye echipiri shafts kune yega yega clutch;
- cylindrical main giya (yemotokari dzine kumberi-vhiri dhiraivha);
- musiyano (kumberi-vhiri motokari motokari).
Kana iwe uine kumashure-vhiri dhiraivha mota ine DSG kutapurirana, ipapo iyo huru giya uye musiyano unowanikwa mune hombe axle dzimba, kunyangwe iwo akabatana akabatana negiya bhokisi uye anogovera torque zvakaenzana kumavhiri ekutyaira.
Iyo mudziyo zvakare zvakanyanya zvinoenderana nehuwandu hwemagiya. Saka, pamotokari ine 6-speed DSG gearbox, clutch ndeye "wet" yemhando, kureva, ma-clutch discs ari mumafuta emafuta, izvo zvinoderedza kupesana. Pa7-speed gearboxes, iyo clutch ndeye "yakaoma" mhando. Iri pasi pekukurumidza kupfeka, zvisinei, nenzira iyi zvinokwanisika kuwana mari yakakosha paATF gear mafuta: munyaya yekutanga, inoda anenge 6-7 malita, uye yechipiri - kwete kupfuura maviri.
Nheyo yekushanda kwebhobhoti gearbox
Nheyo yacho iri nyore. Saka, pane akajairwa makanika, mutyairi anofanirwa kuchinjika kubva kune imwe kumhanya kuenda kune imwe nekuchinja gearshift lever. Pa "robhoti" DSG, magiya maviri anobatanidzwa panguva imwe chete - pasi uye kumusoro. Yepazasi iri kushanda, uye yechipiri iri kuita idling. Nekuwedzera kukurumidza, kuchinja kunoitika mugumi chesekondi.
Kana iwe wasvika pakumhanya kwepamusoro, saka giya rezasi rinoshanda mune idle mode. Iyo ECU inotarisisa maitiro ese aya. Masensa akasiyana-siyana anoongorora crankshaft kumhanya, throttle chinzvimbo uye gasi pedal chinzvimbo. Ruzivo runopinda muchikamu chekutonga uye sarudzo inoitwa yekuchinja giya. Pulses inotumirwa kune hydraulic actuators (solenoid valves, hydraulic circuit) uye iyo yakakwana yekumhanya mode inosarudzwa pane imwe chikamu chemugwagwa.
Zvakanakira uye kuipa kweDSG
Nehurombo, isu tinomanikidzwa kutaura chokwadi chekuti, kunyangwe nehunyanzvi hwavo, maviri-disiki robhoti magiya mabhokisi ane zvakawanda zvakaipira:
- mutengo mukuru webasa;
- kukurumidza kupfeka kwezvikamu zvekukwesha (kunyanya ne clutch yakaoma);
- vatyairi vanonyatsoziva nezvematambudziko aya, saka zvinogona kunetsa kutengesa mota yakashandiswa.
Kunyange iyo waranti inoshanda, matambudziko haaonekwe. Sezvo mutemo, ndiyo clutch discs inokundikana nekukurumidza. Chenjerera kune chokwadi ichi: kana pane DSG-6 (yakaoma mhando) dhisiki inogona kungoshandurwa, ipapo paDSG-7 unofanirwa kuisa zvachose clutch itsva, iyo inodhura senge gearbox nyowani.
Iyo yemagetsi unit pachayo uye ma actuators zvakare akatetepa. Kana yakanyanyisa, ma sensors anogona kupa ruzivo rwakashata kune ECU, zvichiita kuti kusawirirana mukutonga uye jerks dzakapinza dzinonzwa.
Nzira iri nyore yekukurumidza "kuuraya" irobhoti giya bhokisi ndeyekuchengetedza mota pamarambi emigwagwa kana mumigwagwa ine brake pedal, uye kwete nekuchinja kune kwayakarerekera.
Zvakangodaro, magiya mabhokisi akadaro anoramba achigadzirwa, nekuti ane akawanda mabhenefiti:
- kuwedzera kwehupfumi kushandiswa kwemafuta - kuchengetedza kusvika ku10%;
- kuderedza kuburitsa kunokuvadza nharaunda;
- yakanakisa accelerating dynamics;
- kutasva kunyaradza, nyore kushanda.
Hupenyu hwebasa hunosvika paavhareji ye150 zviuru zvemakiromita.
Kubva pane zvataurwa, vapepeti veVodi.su vanokurudzira kuti utore nzira ine mutoro pakusarudza mota yakashandiswa neDSG. Kana wakatenga motokari itsva, zvino tevera mirairo yemugadziri kuitira kuti usapinda mumari yekugadzirisa mari.
