Blatnický, MiroslavSamaš, VladimírDižo, Ján2025-01-2020241337-8996https://drepo.uniza.sk/handle/hdluniza/1184The scope of this article covers potential technologies for transmission mechanisms with variable gear ratios that can be applied to electric traction. A transmission with an adjustable gear ratio allows for the adaptation of the gear ratio according to usage conditions. By adjusting the gear ratio and consequently the traction forces, we can enhance driving parameters, e.g. improved both efficiency and range. The paper theoretically examines various transmissions with variable gear ratios and compares their parameters in the context of electric drives.otherelectric tractiontransmissiontraction forceArticlehttps://doi.org/10.26552/tech.C.2024.4.4
