THE DEVELOPMENT OF AN OPTIMUM WHEEL PROFILE FOR SELF-STEERING TRUCKS UNDER HEAVY AXLE LOAD CONDITIONS

The development of the self-steering truck utilizing profiled wheeltreads has resulted in a drastic reduction in both wheel flange and tread wear. As a result, a variety of wheeltread profiles with significantly different characteristics may be designed which will retain their contours over extended periods of service. The development of the modified drooping conicity profile is described which is considered to optimize wheel/rail contact conditions for decreased wear and increased fatigue life.
