Kumvetsetsa Zomwe Torque Steer Ili Pagalimoto Yoyendetsedwa ndi FWD
Magalimoto oyendetsedwa ndi mawilo akutsogolo (FWD) amadziwika kuti amagwira ntchito bwino, ndi opapatiza, komanso mosavuta kugwiritsa ntchito tsiku ndi tsiku. Komabe, pali chizindikiro chimodzi chomwe nthawi zambiri chimakambidwa ndi okonda magalimoto komanso eni magalimoto amphamvu: torque steer. Chodabwitsa ichi chingapangitse galimoto "kukoka" chiwongolero kumbali imodzi panthawi yothamanga, makamaka pamene pedal ya gasi ikanikizidwa mwamphamvu. Nkhaniyi ikambirana za torque steer, zomwe zimayambitsa, nthawi yomwe imachitika nthawi zambiri, komanso momwe mungachepetsere zotsatira zake.
Kodi Torque Steer ndi chiyani?
Mphamvu yoyendetsa galimoto (torque steer) ndi chizolowezi cha galimoto yoyendetsa galimoto kutsogolo (ndipo nthawi zina yoyendetsa galimoto kutsogolo) kutembenukira kumanzere kapena kumanja ikathamanga, ngakhale kuti dalaivala akuyesera kusunga mzere wowongoka. Chizindikiro chodziwika kwambiri ndi kukoka chiwongolero kapena kumva galimoto "ikuthamanga" kumbali imodzi pamene mphamvu ya injini yamphamvu imayikidwa pamawilo akutsogolo.
Kuyendetsa galimoto mozungulira sikukutanthauza kuti galimotoyo yasweka. Kumafotokozedwa bwino kwambiri chifukwa cha kapangidwe kake ndi ukadaulo m'galimoto yomwe mawilo ake akutsogolo amagwira ntchito ziwiri: kuyendetsa galimotoyo ndi kuyiyendetsa.
N’chifukwa Chiyani Magalimoto Oyenda Pamawilo Akutsogolo Amakonda Kuyendetsa Mozungulira?
Mu galimoto yoyendetsa mawilo akumbuyo (RWD), mawilo akutsogolo ndi omwe ali ndi udindo woyendetsa, pomwe mphamvu yoyendetsera imachokera ku mawilo akumbuyo. Mu galimoto yoyendetsa mawilo akutsogolo, mawilo akutsogolo ayenera kuchita ntchito ziwiri nthawi imodzi—kuyendetsa ndi kutembenuka. Pamene mphamvu yayikulu imatumizidwa ku mawilo akutsogolo, mphamvu pa gudumu lililonse zimakhala zosalingana. Pakakhala kusalingana kwa mphamvu yoyendetsera kumanzere ndi kumanja, galimotoyo imakonda kutembenukira mbali ina.
Mphamvu ya injini ikakula (monga injini ya turbo kapena galimoto yosinthidwa), mphamvu ya torque steer imakulanso.
Zifukwa Zazikulu Zopangira Torque Steer
Kuthamanga kwa torque nthawi zambiri kumachitika chifukwa cha zinthu zosiyanasiyana. Nazi zifukwa zofala kwambiri:
1. Kusiyana kwa Utali wa Driveshaft (Axle)
Magalimoto ambiri oyendera mawilo akutsogolo amagwiritsa ntchito ma driveshaft akumanzere ndi akumanja a kutalika kosiyana chifukwa cha malo osafanana a injini ndi ma gearbox. Driveshaft yayitali imakonda kupotoka kwambiri ikagwiritsidwa ntchito pa torque, kotero torque yake imatha kusiyana pang'ono ndi mbali yayifupi. Kusiyana kumeneku pakuyankha ndi komwe kumapangitsa galimoto kukoka mbali imodzi.
M'magalimoto ena, opanga magalimoto amatha kuletsa izi pogwiritsa ntchito shaft yapakati kuti kutalika koyenera kwa ma driveshaft akumanzere ndi akumanja kukhale koyenera.
2. Kugwira Matayala Kumanzere ndi Kumanja Sikofanana
Ngati matayala akumanzere ndi akumanja ali ndi mphamvu zosiyana zogwirira—chifukwa cha mpweya wosiyanasiyana, mikhalidwe yosagwirizana ya msewu, kuwonongeka kwambiri pa tayala limodzi, kapena mitundu/zosakaniza zosiyanasiyana—ndiye kuti gudumu limodzi “lidzaluma” kwambiri. Gudumu lokhala ndi mphamvu zambiri lidzalandira mphamvu yogwira bwino, zomwe zimapangitsa kuti galimotoyo ikhale ndi mphamvu yosinthasintha.
Mikhalidwe ya msewu imagwiranso ntchito: phula lokhala ndi zigamba, misewu yokhala ndi mikwingwirima, malo otsetsereka mbali imodzi, kapena zizindikiro za msewu wotsetsereka zingapangitse kuti torque steer ikhale yovuta kwambiri.
3. Kugawa Kulemera ndi Kuyimitsa Geometry
Magalimoto oyendetsa magudumu akutsogolo nthawi zambiri amakhala ndi katundu wolemera kwambiri wamagudumu akutsogolo chifukwa injini ndi magiya zimakhala kutsogolo. Pakuthamanga, kusuntha kulemera kumachitika kumbuyo, zomwe zimachepetsa katundu pamagudumu akutsogolo. Ngati kuchepetsa kulemera kumeneku sikuli kofanana (mwachitsanzo, chifukwa cha mikhalidwe yoyimitsidwa, kusiyana kwa kutalika, kapena makonda olinganiza), magudumu akumanzere ndi akumanja amatha kutaya mphamvu mosiyana, zomwe zimapangitsa kuti chiwongolero chikoke.
Maonekedwe a matayala osunthika, monga caster, camber, ndi toe, amathandizanso kudziwa momwe mphamvu za matayala zimayendera ku chiwongolero. Kusakhazikika bwino kungapangitse kuti torque steer ichitike.
4. Chochitika Chosiyana ndi Chozungulira Mawilo
Pa nthawi yothamanga kwambiri, mawilo akutsogolo amatha kuzungulira mawilo. M'magalimoto omwe ali ndi ma differentials otseguka, mphamvu yamagetsi imakonda "kusintha" ku gudumu lomwe limakonda kutsetsereka. Gudumu limodzi likatsetsereka ndipo linalo likadali ndi mphamvu yokoka, galimotoyo ingamve ngati ikukoka kapena chiwongolero chingatembenuke pang'ono chifukwa cha kusiyana kwa mphamvu yokoka.
Mu magalimoto omwe ali ndi Limited Slip Differential (LSD), mphamvu yogwira galimoto nthawi zambiri imayendetsedwa bwino, koma mphamvu yoyendetsa galimoto imatha kumveka "yolimba" kapena kukhala ndi mawonekedwe osiyana chifukwa cha kufalikira kwa mphamvu yogwira galimoto ku mawilo ogwiritsira ntchito grippier. Kwenikweni, mphamvu yosiyana imakhudza momwe mawilo akutsogolo amachitira "mwachilengedwe" akagwiritsidwa ntchito ndi mphamvu yokwera.
5. Kuyika Injini ndi Kusinthasintha pa Zigawo
Kuyika injini mofooka kapena ma bushing owonongeka kungayambitse kuti injini/ma transmission ayende panthawi yothamanga. Kusunthaku kungasinthe pang'ono ngodya yogwirira ntchito ya driveshaft, zomwe zimakhudza mphamvu yotumizira, ndipo pamapeto pake zimayambitsa kukoka kwa chiwongolero. Izi zimachitika kawirikawiri m'magalimoto akale kapena omwe amagwiritsidwa ntchito nthawi zambiri pothamanga kwambiri.
Kodi Torque Steer Imadziwika Kwambiri Liti?
Kuthamanga kwa torque nthawi zambiri kumaonekera kwambiri pazochitika izi:
1. Kuthamanga kwathunthu mu giya yotsika (giya yoyamba kapena yachiwiri), makamaka m'magalimoto okhala ndi turbo omwe ali ndi torque yayikulu pa liwiro lapakati.
2. Msewu ndi wosagwirizana kapena pamwamba pake pali kusiyana pakati pa mbali zakumanzere ndi zakumanja.
3. Mukatuluka pakona, gwiritsani ntchito mpweya wambiri, chifukwa mawilo akutsogolo akuzungulira ndi kutumiza mphamvu nthawi imodzi.
4. Magalimoto amphamvu kwambiri okhala ndi matayala wamba (matayala opapatiza kapena zinthu zosamata kwambiri), kotero kuzungulira kwa mawilo kumachitika mosavuta.
5. Magalimoto osinthidwa: Kukonzanso mapu a ECU, kukweza turbo, kapena kukweza mphamvu ya galimoto nthawi yomweyo popanda kukweza mphamvu ya galimoto kapena kuyimitsa galimoto.
Kodi Torque Steer Ndi Yoopsa?
Nthawi zambiri torque steer si yoopsa ngati dalaivala ali wokonzeka ndipo galimoto ili bwino. Komabe, ikhoza kukhala vuto la chitetezo ngati:
- zinachitika mwadzidzidzi pamene panali kudutsana,
- msewu woterera,
- dalaivala wachita mantha ndipo wakonza chiwongolero mopitirira muyeso,
– kapena galimotoyo imazunguliridwa kwambiri ndi gudumu moti njira ya galimotoyo imakhala yovuta kuisamalira.
M'magalimoto amakono, njira zowongolera kuyenda (TCS), njira zowongolera kukhazikika (ESC), ndi njira zamagetsi zosiyanitsira magalimoto zimathandiza kuchepetsa vutoli mwa kuwongolera kuzungulira kwa mawilo ndi kuchepetsa mphamvu ya mawilo pakafunika kutero.
Momwe Mungachepetsere Kuthamanga kwa Torque
Simungathe kuzichotsa kwathunthu nthawi zonse, koma mutha kuchepetsa kwambiri mphamvu zake:
1. Onetsetsani kuti matayala ali bwino komanso ali bwino.
- Gwiritsani ntchito matayala akumanzere ndi akumanja omwe ali ndi zofunikira zomwezo.
- Onetsetsani kuti kuthamanga kwa tayala kuli kofanana.
- Sinthani matayala nthawi zonse ndikuwonetsetsa kuti palibe mabampu kapena kuwonongeka kofanana.
2. Chitani kulinganiza mawilo ndikuyang'ana kuyimitsidwa
Kuyimitsa bwino mawilo kumathandiza kuti mawilo "ayende bwino" ndipo amachepetsa chizolowezi cha galimoto kukoka. Onaninso:
- ndodo yomangira,
- mpira wolumikizana,
- mkono wozungulira,
- zoziziritsa ku mantha,
chifukwa zinthu zakale zimatha kuwononga mphamvu ya torque steer.
3. Samalani ndi choyikira injini ndi shaft yoyendetsera galimoto
Ngati chiwongolero chayamba kuoneka ngati chikukokedwa pafupipafupi ngakhale kuti matayala ndi kukhazikika bwino, onani:
- zomangira injini/zomangira zotumizira,
- CV yolumikizana,
- mkhalidwe wa shaft yoyendetsera galimoto.
Zinthu zotayirira kapena zosweka zingayambitse kuyankha kosasinthasintha kwa mphamvu yamagetsi.
4. Kukweza Kogwira Ntchito ndi Kusiyanitsa (Kwa Okonda/Osintha)
Kwa iwo omwe akuwonjezera mphamvu, ganizirani izi:
- matayala okulirapo kapena zinthu zomata kwambiri,
– LSD (yamakina kapena yamagetsi, kutengera nsanja),
- kukhazikitsa bwino kuyimitsidwa.
Izi sizimangopangitsa galimoto kukhala yachangu, komanso yosavuta kuyilamulira ikakhala ndi mphamvu yayikulu.
5. Njira Zoyendetsera Galimoto
- Pewani kuponda mpweya mwadzidzidzi pamalo otsetsereka kapena otupa.
- Gwirani chiwongolero mwamphamvu mukathamanga kwambiri.
– Ngati galimoto yayamba kukoka, konzani pang'onopang'ono (musakonze mopitirira muyeso).
Mapeto
Kuthamanga kwa torque steer ndi chinthu chofala kwambiri m'magalimoto oyendetsa mawilo akutsogolo pomwe kuthamanga kwambiri ndi torque zimayambitsa kusalingana kwa mphamvu yoyendetsera pakati pa mawilo akumanzere ndi akumanja. Choyambitsa nthawi zambiri chimakhala kuphatikiza kusiyana kwa kutalika kwa ma driveshaft, kusagwirizana kwa matayala, mawonekedwe oimika, mawonekedwe osiyana, komanso momwe injini imayikidwira. Chochitikachi ndi chofala, makamaka m'magalimoto amphamvu kapena osinthidwa a mawilo akutsogolo.
Ndi kukonza bwino matayala ndi ma suspension, zida zoyendetsera bwino, komanso njira zoyenera zoyendetsera, torque steer ingachepe, zomwe zimapangitsa kuti galimoto ikhale yabwino komanso yotetezeka. Pomaliza, kumvetsetsa torque steer kumathandiza oyendetsa galimoto kukonzekera bwino makhalidwe a galimoto yoyendetsa mawilo akutsogolo—ndi kusangalala ndi magwiridwe ake ndi kuwongolera kwakukulu.
