Sainzi Yekutanga yeMasisitimu Ekutyaira Mavhiri Emota
Chitima chekutyaira mota chinhu chakatevedzana chine chekuita nekutumira simba kubva kuinjini kana mota yemagetsi kuenda kumavhiri. Pasina sisitimu iyi, simba rinogadzirwa nemagetsi haringashandurwe kuita kufamba kwemotokari. Kunzwisisa hwaro hwemasisitimu ekutyaira mota kwakakosha kwete chete kune vadzidzi vemotokari asiwo kune vanoshandisa mota, zvichivabatsira kunzwisisa mashandiro adzo, maitiro ekudzichengetedza, uye kuti nei mota dzakasiyana dziine hunhu hwakasiyana—semuenzaniso, dzinoshandisa mafuta zvakanyanya, dzine simba rakawanda, kana kuti dzakagadzikana mumigwagwa inotsvedza.
1. Pfungwa Yekutanga: Kubva Simba Kuenda Kukufamba
Mumotokari dzemazuva ose, simba remakemikari riri mumafuta rinoshandurwa kuita simba remakanika kuburikidza nekupisa muinjini. Mumotokari dzemagetsi, simba remagetsi rinobva mubhatiri rinoshandurwa nemota yemagetsi kuita simba remakanika nenzira yekutenderera. Kutenderera uku kunofanira kudzorwa, kuwedzera kana kuderedza torque yayo, uye kwozoendeswa kumavhiri. Apa ndipo panoshanda drivetrain.
Mufizikisi, zvinhu zvikuru zvinobatanidzwa i torque nesimba. Torque ndiyo "simba rinotenderedza" rinoita kuti mavhiri atenderere, nepo simba riri kumhanya kwebasa rinogadzirwa neinjini. Mota dzinogona kukwira makomo zviri nyore dzine torque yakakwira pa revs yakaderera, nepo mota dzinogona kumhanya nekukurumidza dzichida simba rakakwana kuti dzirambe dzichimhanya zvakanyanya.
2. Zvikamu Zvikuru zveSisitimu yeDrive
Kunyangwe zvinhu zvakasiyana-siyana pakati pemhando dzemotokari (dzinoshandiswa nemaoko, dzinozvishandisa otomatiki, dzemagetsi), nzira yekufambisa mota inowanzo kuve ne:
1. Simba rinobva: injini yekupisa mukati (ICE) kana mota yemagetsi.
2. Clutch kana torque converter: inobatanidza uye inotonga kugoverwa kwesimba kubva kuinjini kuenda kugedhi.
3. Kutapurirana (gearbox): kunochinja chiyero chekutenderera uye torque kuburikidza nechiyero chegiya.
4. Driveshaft/propeller shaft: inotumira kutenderera kuenda ku axle (kazhinji paRWD/4WD).
5. Differential (final drive/axle): inokamura simba remavhiri ekuruboshwe nerudyi uye inobvumira kutenderera kwakasiyana pakutenderera.
6. Axle (hafu yemubato): inotumira kutenderera kubva padifferential kuenda kumavhiri.
7. Mavhiri nematayi: shandura torque kuita simba rekukweva pamusoro pemugwagwa.
Chikamu chimwe nechimwe chine basa rakananga rekuona kuti simba rinotumirwa zvakanaka, zvakanaka, uye zvakachengeteka.
3. Basa reKutumira: Kudzora Torque uye Kumhanya
Injini ine rev range inoshanda zvakanaka. Kana revs dzakaderera zvakanyanya, injini inogona kumira; kana dzakanyanya kukwira, kushandiswa kunowedzera uye njodzi yekukuvadzwa inowedzera. Basa regetsi nderekuchengetedza injini iri mukati me rev range yakakodzera uku ichiramba ichipa torque inodiwa nemavhiri.
– Giya rakaderera (chiyero chepamusoro): torque yakakwira, kumhanya kwakaderera. Yakakodzera kutanga, kukwira, uye kutakura mitoro.
– Giya rakakwirira (chiyero chidiki): torque yakaderera, kumhanya kwakakwirira. Yakakodzera kutyaira zvakanaka mumigwagwa yakati sandara.
Mugetsi rinotenderera otomatiki, shanduko dzemagiya dzinoitika pasina kupindira kwemutyairi (zvichienderana nemasisitimu ehydraulic uye madhiraivha emagetsi). Mumotokari dzemagetsi, mamodheru mazhinji haashandise giya remagiya rine masiteji akawanda semota dzemazuva ese nekuti mota dzemagetsi dzine torque yakakura inoshanda, kunyangwe paine kudzikiswa kwemagiya kuti aenderane nekumhanya kwemota nemavhiri.
4. Clutch uye Torque Converter: Kugadzirisa Simba
Mumota dzinofambisa magiya nemaoko, clutch inobvumira injini kuti irambe ichishanda kunyangwe mota yamiswa. Kana clutch pedal yadzikiswa, injini negedhi zvinobviswa. Kana yaburitswa zvishoma nezvishoma, simba rinofambiswa zvishoma nezvishoma, zvichiita kuti pave nekufamba kwakanaka.
Mumota dzemazuva ano dzinozvigadzira dzoga, clutch inotsiviwa ne torque converter, mudziyo we hydrodynamic wakazara nemvura unobvumira kuti simba rifambiswe zvakanaka. Torque converter inogonawo "kuwedzera" torque pasi pemamwe mamiriro ezvinhu, zvichibatsira kana mota yatanga kufamba kubva payakamira.
5. Kusiyana: Sei Mavhiri Ekuruboshwe Nekurudyi Achifanira Kutenderera Zvakasiyana?
Kana mota ikatenderera, vhiri rekunze rinofamba chinhambwe chakakura kupfuura vhiri remukati. Izvi zvinoreva kuti vhiri rekunze rinofanira kutenderera nekukurumidza. Kana mavhiri ese ari maviri akamanikidzwa kutenderera nekumhanya kumwe chete, matai anotsvedza, dhiraivha inorema, uye zvikamu zvedrivetrain zvinopera nekukurumidza. Kusiyana kunogadzirisa dambudziko iri nekubvumira mavhiri ekuruboshwe nerudyi kutenderera nekumhanya kwakasiyana.
Zvisinei, madhiri akajairwa ane dambudziko: kana vhiri rimwe rikarasikirwa nekukweva (semuenzaniso, mumatope kana mumigwagwa inotsvedza), simba rinowanzo yerera richienda kuvhiri rinotenderera zviri nyore (riri rinotsvedza). Kurwisa izvi, dzimwe mota dzinoshandisa Limited Slip Differential (LSD) kana electronic traction control system inodzivirira kutsvedza kwevhiri nekubhureka.
6. Rudzi rweDrive: FWD, RWD, AWD, uye 4WD
Magadzirirwo esystem yedrivetrain anokanganisa hunhu hwemotokari:
a. Kufambisa Mavhiri Epamberi (Front Wheel Drive)
Simba rinopfuudzwa kumavhiri epamberi. Zvakanakira:
- Yakareruka uye inoshanda zvakanyanya (zvikamu zvishoma).
– Nzvimbo yekabhini yakakura nekuti haidi shaft refu yepropeller.
- Kazhinji zviri nyore kune vatyairi vatsva vari mumigwagwa inotsvedza.
Zvakashata:
– Mavhiri epamberi ane mabasa maviri: kutyaira nekufambisa, saka anowanzo kundwa nekusafambisa zvakanaka.
- Kana simba rakawanda, torque steer (kudhonza vhiri rechiteringi) inogona kuitika.
b. RWD (Kutyaira neVhiri Rekumashure)
Simba rinopfuudzwa kumavhiri ekumashure. Zvakanakira:
- Kupatsanurwa kwemabasa: kutyaira mavhiri epamberi, kusunda mavhiri ekumashure.
- Kugona kubata nekukurumidzisa mota zviri nani.
Zvakashata:
- Zvimwe zvikamu (propeller shaft, rear differential).
– Mumigwagwa inotsvedza, mavhiri ekumashure anorasikirwa nekukweva zviri nyore kana asingabatsirwi nesystem yekudzora kugadzikana.
c. AWD (Drive Yese Nemavhiri)
Mavhiri ese anogona kugamuchira simba, kazhinji nehurongwa hwe otomatiki hunogovera torque zvichienderana nemamiriro ezvinhu. Yakakodzera:
– Kubata zviri nani mumigwagwa ine mvura, jecha, kana sinou.
- Kugadzikana panguva yekumhanyisa.
Dambudziko guru nderekuti huremu uye kushandiswa kwemafuta zvinowanzowedzera.
d. 4WD (Inotyaira nemavhiri mana)
Kazhinji yakagadzirirwa kushandiswa kunze kwemugwagwa, ine bhokisi rekuchinjisa mota uye nzira dze2H/4H/4L. Nzira ye4L inopa chiyero chakaderera kwazvo che torque yakakwira kana uchikwira makomo akanyanya kana kufamba munzvimbo dzakaoma. Sisitimu iyi yakasimba, asi inowanzo kurema uye inoda kugadziriswa kwakawanda.
7. Kubata: Kusangana kweMatairi, Nzvimbo yeMugwagwa, uye Torque
Pakupedzisira, mavhiri haafambise mugwagwa zvakananga—kukweshana kuri pakati petai nepamusoro ndiko kunoita basa racho. Kana simba rayo rakanyanya kukwira kana tichienzanisa nekubata kwetai, tai rinotenderera uye mota haifambi zvakanaka. Ndokusaka mota dzemazuva ano dzichishandisa:
- ABS yekudzivirira mavhiri kuti asavharike kana mabhureki.
– TCS (Traction Control System) kudzivirira mavhiri ekutyaira kuti asatsvedze panguva yekumhanyisa mota.
– ESC (Electronic Stability Control) kuchengetedza kugadzikana kana mota yatanga kurasikirwa negwara.
Izvi zvinoreva kuti sisitimu yekufambisa mavhiri haigone kuparadzaniswa nesisitimu yebhureki uye yekudzora kwemagetsi.
8. Kugadzirisa Kwekutanga Kuti Sisitimu Yekutyaira Igare Kwenguva Refu
Mamwe matanho ekugadzirisa ane chekuita zvakananga ne drivetrain:
– Gara uchichinja oiri yekufambisa mafuta zvichienderana nezvinodiwa nemugadziri.
– Tarisa axle/differential oil (kunyanya RWD/4WD).
– Ita shuwa kuti CV joint boot (inowanzo shandiswa paFWD) haina kubvaruka kuitira kuti mafuta asabude uye tsvina isapinde.
– Dzivisa tsika dzinoshandisa zvisina kunaka zvikamu: kutanga kamwe kamwe, kusiya clutch "pakati-mukati" kwenguva yakareba, kana kumanikidza mota kukwira mugomo negiya risiri iro.
– Chengetedza kumanikidzwa kwematai uye mamiriro awo, nekuti matai anokanganisa kudhonzwa kwemotokari uye mutoro wekutyaira.
Penutup
Sainzi huru yemotokari dzinofambisa mota inoongorora kuti simba rinobva muinjini kana mota yemagetsi rinogadziriswa sei uye rinoendeswa sei mukufamba pamavhiri. Inosanganisira zvinhu zvakakosha zvakaita se clutch kana torque converter, transmission, driveshaft, differential, uye matai senzvimbo yekupedzisira inogadzira kudhonza. Magadzirirwo akasiyana emotokari dzinofambisa mota—FWD, RWD, AWD, uye 4WD—anogadzira hunhu hwakasiyana hwemotokari maererano nekushanda zvakanaka, kugadzikana, kugona kutenderedza mota, uye kushanda kwayo munzvimbo dzakaoma. Nekunzwisisa misimboti iyi, tinogona kushandisa mota zvakakodzera, kuchengetedza hupenyu hwechikamu, uye kunzwisisa kuti nei kuchengetedza motokari kuchikosha pakuchengetedza kutyaira uye kunyaradzwa.
