Torsion Bar vs. Coil Orisun omi: Eyi ti o tọ fun Eto idadoro rẹ?
You're designing a vehicle's suspension and face a fundamental choice. Ṣe o lo orisun omi okun ibile tabi igi torsion fifipamọ aaye kan? Yiyan eyi ti ko tọ le ṣe iparun gigun didara[1] ki o ba gbogbo apẹrẹ ẹnjini rẹ jẹ.

Bawo ni Idaduro Pẹpẹ Torsion kan Ṣiṣẹ Lootọ?
O wo igi torsion kan, and it's just a simple steel rod. Bawo ni iyẹn ṣe ṣee ṣe gbe ọkọ nla nla kan? It doesn't compress or stretch, ṣiṣe awọn oniwe-iṣẹ dabi ohun to.
Ọpa torsion n ṣiṣẹ bi orisun omi nipa yiyi ni gigun rẹ. One end of the bar is fixed to the vehicle's frame, nigba ti awọn miiran ti wa ni so si a Iṣakoso apa. Bi kẹkẹ ti n lu ijalu kan ti o nlọ si oke, o fi agbara mu apa iṣakoso lati yi igi naa pada, eyi ti o koju išipopada.
Idan ti a igi torsion[^3] wa ninu ohun elo rẹ ati itọju ooru. It has to be made from incredibly strong spring steel that can twist repeatedly without deforming or breaking. Ninu ise wa, producing a bar with a perfectly consistent grain structure along its entire length is the main challenge. Eyikeyi aaye ailera le ja si ikuna lojiji. The bar's resistance to this twisting motion is what provides the spring force. O jẹ ojuutu didara ati iyalẹnu logan, which is why it became so popular on heavy-duty trucks and SUVs that needed high ilẹ kiliaransi[4] ati apẹrẹ idadoro ti o tọ.
