Gudumu lolimbitsa thupi limapangidwa makamaka ndi chipolopolo chokhazikika, mkono wolimbitsa thupi, thupi la gudumu, kasupe wozungulira, chogwirira chozungulira ndi chogwirira chopindika, ndi zina zotero. Limatha kusintha mphamvu yolimbitsa thupi malinga ndi kulimba kosiyanasiyana kwa lamba, kuti makina otumizira magetsi akhale okhazikika, otetezeka komanso odalirika.
Gudumu lolimbitsa ndi gawo lovala la galimoto ndi ziwalo zina, lamba lomwe limakhala nthawi yayitali ndi losavuta kuvala, payipi ya lamba yopyapyala mozama komanso mopapatiza idzawoneka ngati yayitali, gudumu lolimbitsa likhoza kusinthidwa lokha kudzera mu hydraulic unit kapena damping spring malinga ndi kuchuluka kwa lamba lomwe lavala, kuphatikiza apo, lamba lolimbitsa likuyenda bwino, phokoso lochepa, ndipo lingalepheretse kutsetsereka.
Gudumu lokakamiza ndi la ntchito yokonza nthawi zonse, yomwe nthawi zambiri imafunika kusinthidwa kwa makilomita 60,000-80,000. Nthawi zambiri, ngati phokoso losazolowereka kumapeto kwa injini kapena malo omwe ali ndi mphamvu yokakamiza magudumu okakamiza amapatuka kwambiri pakati, zikutanthauza kuti mphamvu yokakamiza sikokwanira. Ndikofunikira kusintha lamba, gudumu lokakamiza, gudumu losagwira ntchito ndi gudumu limodzi la jenereta pamene makina othandizira kutsogolo amamveka molakwika pa makilomita 60,000-80,000.
