Mutanen da ke magana game da dakatarwar mota sau da yawa suna nufin "shock absorbers da struts". Bayan jin wannan, ƙila ka yi mamakin menene strut, shin daidai yake da abin da ake sha, kuma kana buƙatar damuwa game da strut ɗin motarka ko motarka.
Abu na farko da za a fahimta game da strut shi ne cewa yana daya daga cikin abubuwan da ke cikin dakatarwar mota - tsarin sassan da ke haɗa ƙafafun da sauran motar. Manyan ayyuka guda uku na dakatarwar kowace mota:

Bada abin hawa don kunna martani ga shigarwar direba. (Tsarin tuƙi ana iya ɗaukarsa wani ɓangare na dakatarwa ko tsarin daban, amma a kowane hali, dakatarwar dole ne ya ba da damar ƙafafun su motsa yayin da abin hawa ke juyawa.)
Ya bayyana cewa, ba kamar yawancin sauran abubuwan dakatarwa ba, strut yawanci yana shiga cikin duk waɗannan ayyuka guda uku.
Abin da ke cikin rakiyar
Cikakken taron strut haɗuwa ne na manyan sassa biyu: bazara da abin sha. (Wani lokaci kalmar "strut" tana nufin kawai wani ɓangare na mai ɗaukar girgiza, amma wasu lokuta ana amfani da kalmar don nufin dukan taron, ciki har da bazara.) Ruwan bazara, wanda kusan ko da yaushe shine maɓuɓɓugar ruwa (wato, marmaro mai siffar coil), yana goyan bayan nauyin abin hawa kuma yana ɗaukar manyan girgiza. Shima na’urar daukar hoto (shock absorber) wacce aka dora sama, ko kasa ko dama a tsakiyar coil spring, ita ma tana goyon bayan wasu ko duka nauyin motar, amma aikinta na farko daya ne da duk wani abin da ake kira shock, wanda shine rage girgiza. (Duk da sunansa, mai ɗaukar girgiza ba ya ɗaukar girgiza kai tsaye - wannan shine aikin bazara - maimakon haka, yana kiyaye motar daga hawan sama da ƙasa bayan an buge shi.) Saboda tsarinsa mai ɗaukar nauyi, strut ɗin ya kamata ya fi ƙarfi fiye da abin sha na al'ada.
Shin duk motoci suna da tagulla?
Ba duka motoci da manyan motoci ne ke da tarkace ba; yawancin ƙirar dakatarwa suna amfani da maɓuɓɓugan ruwa daban-daban da dampers, tare da dampers ba su iya ɗaukar nauyin nauyi. Har ila yau, wasu motoci suna amfani da struts akan ƙafafu guda ɗaya kawai, yawanci ƙafafun gaba, yayin da sauran biyun suna da nau'i daban-daban tare da maɓuɓɓugan ruwa da dampers daban-daban. Lokacin da mota ta kasance a kan ƙafafun gaba kawai, yawanci MacPherson struts ne, waɗanda kuma ana ɗaukar su wani ɓangare na tsarin tuƙi yayin da ƙafafun ke juya su.
Me yasa wasu motoci ke amfani da struts yayin da wasu ke amfani da maɓuɓɓugan ruwa da dampers daban? Ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun abubuwa suna da rikitarwa, amma ga mafi yawan ɓangaren yana zuwa zuwa ciniki tsakanin sauƙi da farashi na farko (fa'ida: struts) da kulawa da aiki (fa'ida: wasu ƙirar dakatarwa ba tare da kullun ba ... yawanci).
