Abstract
The design of the freight bogies used in operation does not allow the traffic of freight trains to be implemented within the schedule of passenger trains. For this purpose, a three-axle bogie has been developed, which allows increasing the design speed of a freight wagon up to 140 km/h. The characteristics of the wheelset elastic linkage with the bogie frame and of the elastic side bearings have an effect on the wagon dynamic qualities.
Research was conducted into the dynamic qualities and impact on the track (experimental trips) of a long-base flat wagon with an increased design speed with two three-axle bogies equipped by experimental buffer plate suspension rod units and elastic side bearings between the bogie and the flat wagon frame. Based on the conducted research, rational technical solutions for the spindle axle box unit the buffer plate suspension rod unit and elastic side bearing were selected.
