4 × 4 pa asphalt. Kodi tiyenera kukumbukira chiyani?

A Poles amatsimikiza za magalimoto oyendetsa magudumu onse. Ma Crossovers ndi ma SUV akuchulukirachulukira. Palinso anthu omwe amalipira ndalama zowonjezera 4 × 4 pogula limousine yapamwamba kapena station wagon. Kodi muyenera kukumbukira chiyani mukamagwiritsa ntchito galimoto yokhala ndi nthambi za nthambi?

Ubwino wa ma wheel drive onse amadziwika bwino. Kupititsa patsogolo kuyendetsa bwino, machitidwe otetezeka m'malo ovuta komanso kuwonjezereka kwamphamvu ndi zina mwa izo. 4 × 4 ilinso ndi zovuta. Izi zimathandizira kugwiritsa ntchito mafuta, kumachepetsa mphamvu, kumawonjezera kulemera kwa galimoto ndikuwonjezera mtengo wogula ndi kukonza. Mavuto ena amatha kupewedwa posamalira kuyendetsa. Makhalidwe oyendetsa amakhudzanso dziko la 4 × 4 yoyendetsedwa ndi magetsi.

Mukayamba, pewani kumasula clutch pa high rpm ndikuwongolera throttle ndi clutch m'njira yochepetsera nthawi yoyenda pa theka la clutch. Magudumu anayi, makamaka okhazikika, amachotsa valavu yotetezera ngati mawonekedwe a gudumu. Pa 4 × 4, zolakwika zamadalaivala zimakhudza kutumiza - chimbale cha clutch chimavutika kwambiri.

Ndikofunikira kwambiri kusunga gudumu lozungulira nthawi zonse. Kusiyanitsa kwakukulu pamlingo wa kupondaponda, mitundu yosiyanasiyana ya matayala pa ma axles kapena kutsika kwapansi kwawo sikuthandiza kufalitsa. Pakuyendetsa kosatha, kusiyana kwa liwiro la ma axles kumapangitsa kusiyana kwapakati kugwira ntchito mosafunikira. Mu analogue ya makina opangira ma multiplate oyendetsedwa ndi magetsi, ma signature omwe amalowa mu ECU amatha kutanthauziridwa ngati zizindikiro za kutsetsereka - kuyesa kupotoza clutch kudzafupikitsa moyo wake wautumiki. Ngati mwasankha kusintha matayala, nthawi zonse mugule seti yathunthu!

M'magalimoto okhala ndi hard drive kupita kutsogolo (otchedwa Part Time 4WD; makamaka magalimoto onyamula ndi ma SUV otsika mtengo), mapindu a magudumu onse amatha kusangalala ndi misewu yotayirira kapena yoyera kwathunthu. Kuyendetsa mumayendedwe a 4WD pamtunda wonyowa kapena phula lachisanu pang'ono ndikotheka mwakuthupi, koma kumapangitsa kupsinjika koyipa pakupatsirana - palibe kusiyana pakati pa ma axle akutsogolo ndi akumbuyo omwe atha kubweza kusiyana kwa liwiro la ma axle mukamakona.

Kumbali inayi, muma crossovers ndi ma SUV okhala ndi plug-in back axle, kumbukirani cholinga cha loko. Batani pa dashboard imagwiritsa ntchito ma multiplate clutch. Tizifikira pazochitika zapadera - poyendetsa m'matope, mchenga wosasunthika kapena chipale chofewa chakuya. M'misewu yokhala ndi mphamvu yokoka bwino, cholumikizira chokhumudwa kwambiri chimakhala ndi kupsinjika kwakukulu, makamaka pakumakona. Sizopanda pake kuti zolemba za opanga zikugogomezera kuti kuyendetsa kumatha kutsagana ndi ma jerks ndi kuchuluka kwa phokoso lambiri kuchokera pansi pa mawilo, ndipo ntchito ya Lock singagwiritsidwe ntchito pa asphalt.

Kuchepetsa mwayi wowonongeka kwa clutch, clutch imatulutsidwa pakompyuta ikadutsa 40 km / h. Mu zitsanzo zambiri, chisankho cha dalaivala sichikumbukiridwa - mutatha kuzimitsa injini, ntchito ya Lock iyenera kuyatsidwanso, yomwe imachotsa mwangozi, kuyendetsa galimoto yaitali ndi clutch yokhumudwa kwambiri (mwinamwake, kuphatikizapo ma SUVs aku Korea, pomwe batani loyendetsa loko imagwira ntchito mu 0-1 mode). Tiyenera kugogomezera kuti makina ambiri olumikizidwa ndi magudumu anayi amapangidwa kuti apititse patsogolo pang'onopang'ono, osati kuti azigwira ntchito mokhazikika pa katundu wambiri. Izi ndizoyenera kukumbukira, mwachitsanzo, pamene mukuyesera kuyendetsa galimoto ndi skid yolamulidwa. N'zotheka, koma n'zosatheka kudzaza galimoto - kuyenda kwautali ndi gasi pansi kudzatsogolera kutenthedwa kwapakati pa clutch.

Potengera momwe galimotoyo ikuyendetsedwera, tsatirani malingaliro a wopanga kapena makanika pakusankha mafuta ndi njira. Mafuta omwe ali mu bokosi la gear, chotengera chosinthira ndi kusiyanitsa kumbuyo, nthawi zambiri amaphatikizidwa ndi ma multiplate clutch, ayenera kusinthidwa pafupipafupi. Mu zitsanzo zambiri, aliyense 60 zikwi Km. Mafuta oyambirira a DPS-F ayenera kugwira ntchito bwino mu Honda Real Time 4WD, ndipo pamene mukusintha mafuta ku Haldex, simuyenera kusiyanitsa zosefera - kuyesa kusunga ndalama kungasinthe kukhala ndalama.
