Predelava cestnega vozila za tekmovanje v bočnem drsenju

Zalar, Gašper (author), Ambrož, Miha (mentor)

Vozila, predelana za tekmovanje v bočnem drsenju, zahtevajo drugačno vozno karakteristiko od cestnih vozil. Obravnavali smo tako vozilo in njegovo predelavo v vozilo za tekmovanje v bočnem drsenju. S spreminjanjem samo parametrov zadnjih vzmeti smo dosegli želeno nevtralno krmiljeno vozilo, ki je bilo hkrati nastavljeno na najnižjo višino, ki jo vzmetenje dopušča. Parametre vzmeti smo določili preko računanja prečnega prenosa teže ter navpične sile na pnevmatike. Na koncu smo eksperimentalno potrdili želeno vozno karakteristiko.

• Title: Conversion of a road vehicle for drift competition

Abstract

Drift competition vehicles demand different driving characteristics compared to road vehicles. In this paper a drift competition vehicle as well as its modifications are presented. By changing only the properties of the springs on the rear axle, a desired neutral steer characteristic was achieved at the lowest possible ride height. The required spring properties were determined by calculating the lateral weight transfer and vertical tire forces. Finally, the desired driving characteristic was experimentally confirmed.
