Analysis of mechanical properties of resilient tram wheel screws
In recent years ZET (Zagreb Municipality Transit System) has acquired 140 new low-floor trams TMK 2200 built by Croatian consortium – Crotram. New trams introduced new wheel type as well. Instead of monoblock wheels used on older tram units, the new trams run on resilient wheels Bochumer Verein BO 84, which consist of wheel tyre mounted on to the wheel body with resilient pads in between designed for vibration absorption. Two wheel components are bolted together using 24 high quality screws M22x58 and M16x60, 12 of each type. The instructions provided by the tram manufacturer is to replace the screws after the second tyre refitting, hence after 200 000 km in operation. This procedure requires acquisition of 13400 new screws annually, which represents a significant expense for the tram maintenance. This fact has led to investigation of wheel screw behaviour over the exploitation period in order to examine their mechanical properties and to investigate if they are safe for further use, therefore saving valuable resources.
