Mitundu ndi mfundo zoyendetsera mitu yamagalimoto

Chimodzi mwazoletsa zoyambira pamutu chidayambitsidwa ndi Mercedes-Benz mu 1960. Poyamba, adaziyika atapempha wogula. Chakumapeto kwa zaka makumi asanu ndi limodzi, magalimoto onse a Mercedes adapangidwa ndi zopinga pamutu. Mu 60, bungwe lachitetezo la NHTSA lidatsimikizira kufunikira kwa zowonjezera zatsopano ndikulimbikitsa kuyika kwake kwa onse opanga magalimoto.

Kodi headrest imagwira ntchito zotani?

Kuphatikiza pa mpando wamagalimoto ndichinthu chachitetezo chongokhala, osangokhala gawo labwino. Zonse ndizokhudza momwe thupi lathu limakhalira pampando wamagalimoto kumbuyo kwakumbuyo. Thupi limathamangira mmbuyo, ndipo mutu umatsamira mmbuyo mwamphamvu kwambiri ndikuthamangira patapita kanthawi. Izi zimatchedwa "chikwapu". Mutu wamutuwu umayimitsa kuyenda kwamutu panthawi yomwe ikukhudzidwa, kupewa kuphulika kwa khosi komanso kuvulala pamutu.

Ngakhale osalimbana mwamphamvu, koma mosayembekezereka, mutha kusokonezeka kapena kuphwanya pakhosi lachiberekero. Zaka zowonera zatsimikizira kuti kapangidwe kosavuta kameneka kangopulumutsa miyoyo ndikuteteza kuvulala lalikulu.

Kuvulala kwamtunduwu kumatchedwa "whiplash".

Mitundu yakumutu

Padziko lonse lapansi, magulu awiri a zopinga pamutu amatha kusiyanitsidwa:

1. Zosasintha.
2. Yogwira.

Zomata zokhazokha zamagalimoto ndizokhazikika. Amakhala ngati cholepheretsa kubwerera kumbuyo kwamutu. Pali njira zingapo zopangira. Mutha kupeza zopangira mutu zomwe ndizowonjezera mpando. Koma nthawi zambiri amamangiriridwa padera ngati pedi ndipo amatha kusintha kutalika.

Zoletsa pamutu zogwiritsa ntchito ndi njira yothetsera makono amakono. Ntchito yawo yayikulu ndikupereka mafuta okwanira kumutu kwa woyendetsa mwachangu panthawi yomwe akukhudzidwa. Momwemonso, zoletsa pamutu zogawika zimagawika m'magulu awiri kutengera kapangidwe ka drive:

• makina;
• zamagetsi.

Ntchito yamagetsi yogwira ntchito imakhazikitsidwa ndi fizikiya ndi malamulo a mphamvu zamankhwala. Kukhazikitsa dongosolo la levers, ndodo ndi akasupe. Thupi likamakankhira kumbuyo komwe kumachitika, makinawo amapendekeka ndikugwira mutu koyambirira. Kupanikizika kukachepa, imabwerera pamalo ake akale. Zonsezi zimachitika pakadutsa mphindi.

Kapangidwe kazosankha zamagetsi kutengera:

• Masensa Anzanu;
• Control chipika;
• squib yoyendetsedwa ndi magetsi;
• gawo loyendetsa.

Pakukhudzidwa, thupi limakanikiza pama sensa opanikizika, omwe amatumiza chizindikiritso ku gawo loyang'anira zamagetsi. Kenako poyatsira amayatsa poyatsira ndipo mutu wamutu umapendekera kumutu pogwiritsa ntchito drive. Dongosololi limaganizira za kulemera kwa thupi, mphamvu yake ndi kukakamiza kwake kuwerengera kuthamanga komwe makinawo akuyambitsira. Njira yonseyi imagawika mphindi.

Amakhulupirira kuti makina amagetsi amagwira ntchito mwachangu komanso molondola, koma choyipa chake chachikulu ndi kutayika kwake. Pambuyo poyambitsa, zoyatsira ziyenera kusinthidwa, ndikuphatikizira zida zina.

Kusintha kwa mutu

Onse omangika komanso osanja oyendetsa galimoto akuyenera kusinthidwa. Udindo wolondola ungakhudze kwambiri zotsatira zake. Komanso, pamaulendo ataliatali, malo abwino pamutu amachepetsa kupsinjika kwa msana.

Monga lamulo, zokhazokha pamutu pamutu ndizomwe zingasinthidwe kutalika. Ngati chikaphatikizidwa ndi mpando, ndiye kuti mpando wampando wokha ndi womwe ungasinthidwe. Nthawi zambiri, makina kapena batani limalembedwa kuti "Yogwira". Ndikokwanira kutsatira malangizo. Izi sizimabweretsa zovuta.

Udindo wa khushoni wothandizira kumbuyo kwa mutu wa wokwera kapena woyendetsa umawerengedwa kuti ndi abwino. Komanso, madalaivala ambiri amalangiza kusintha mpando poyamba. Mipandoyo idapangidwira kukula kwa thupi la munthu wolemera pafupifupi 70 kg. Ngati wokwera kapena woyendetsa sakukwanira magawo awa (otsika kapena aatali kwambiri), ndiye kuti zikhale zovuta kusintha momwe makinawo akuyendera.

Zoyipa ndi zovuta zoletsa pamutu

Ngakhale maubwino a makinawa amaposa zovuta, palinso zovuta. Madalaivala ena amaona ntchito ya makina ngakhale ndi kuthamanga pang'ono. Pa nthawi imodzimodziyo, mtsamiro umakhala mopepuka motsutsana ndi mutu. Izi ndizokwiyitsa kwambiri. Muyenera kuzolowera makinawo, kapena kuikonza nokha. Ngati uku ndikulakwitsa kwa fakitare ndipo galimoto ili ndi chitsimikizo, ndiye kuti mutha kulumikizana ndi ogulitsa mwachinsinsi.

Maloko ndi ma levers a makinawo amathanso kulephera. Zida zopanda pake kapena kuwonongeka kungakhale chifukwa. Zowonongeka zonsezi ndizokhudzana ndi zoletsa pamutu zogwira ntchito.

Ziwerengero zikuwonetsa kuti mu 30% ya ngozi zomwe zimakhudza kumbuyo, zinali zoletsa pamutu zomwe zidapulumutsa kuvulala kwa mutu ndi khosi. Titha kunena motsimikiza kuti makina oterewa amangopindulitsa.
