Othandizira

Kukula kwaukadaulo kwapangitsa kuti zitheke kuyambitsa zatsopano zambiri pantchito ya osamalira.

Mbiri ya wiper windshield inayamba mu 1908, pamene chotchedwa "wiper line" chinali choyamba chovomerezeka. Makina ochapira magalasi oyambirira ankagwiritsidwa ntchito ndi dzanja la dalaivala. Patapita nthawi, ku USA, njira ya pneumatic yoyendetsa wipers inapangidwa. Komabe, makinawa anali osagwira ntchito ndipo ankagwira ntchito mosiyana. Galimotoyo ikamathamanga kwambiri, ma wipers amatsika kwambiri. Ndi ntchito yokhayo ya woyambitsa Robert Bosch yomwe idawongolera chowongolera chopukuta chakutsogolo. Galimoto yamagetsi idagwiritsidwa ntchito ngati gwero lagalimoto, lomwe, limodzi ndi zida za nyongolotsi, kudzera munjira ya ma levers ndi ma hinges, zimayika chowongolera kutsogolo kwa dalaivala.

Magalimoto amtundu umenewu wafala kwambiri ku Ulaya, chifukwa nthawi zambiri madalaivala amakumana ndi vuto la nyengo ya ku kontinentiyo.

Masiku ano, chitukuko cha luso lachititsa kuti adziwe zambiri zatsopano (okonza ntchito, masensa a mvula) omwe amayendetsa ntchito ya chipangizochi ndipo samakopa chidwi cha dalaivala.

Tiyeneranso kuzindikira kusintha kwa magetsi. Mpaka posachedwapa, ma motors amagetsi omwe amagwiritsidwa ntchito poyendetsa ma wipers a windshield anali a unidirectional. Chaka chatha Renault Vel Satis adagwiritsa ntchito injini yosinthika koyamba. Sensa yomwe ili mu injini imazindikira malo enieni a mkono wa wiper ndikutsimikizira malo ochuluka a wiper. Kuphatikiza apo, sensa yopangidwa ndi mvula imasintha ma frequency oyeretsa ma windshield malinga ndi mphamvu ya mvula. Dongosolo losintha limazindikira zopinga zomwe zili pagalasi lakutsogolo monga matalala owunjika kapena ayezi womata. Zikatero, malo ogwirira ntchito a wipers amakhala ochepa chabe kuti apewe kuwonongeka kwa makinawo. Ikapanda kugwiritsidwa ntchito, chopukutira pakompyuta chimachisunthira kumalo osungira kunja kwa malo ogwirira ntchito kuti zisasokoneze mawonekedwe a dalaivala komanso kuti zisapange phokoso lowonjezera kuchokera kumayendedwe a mpweya.

Chinthu chimodzi sichinasinthe kwa nthawi yaitali - mphira wachilengedwe wakhala akugwiritsidwa ntchito popanga mphira kwa zaka zambiri, chifukwa ali ndi katundu wabwino komanso kukana kuvala kwakukulu.
