ABSTRACT:
To achieve low wear and hence a greater shape durability of track parts, it is proposed that the contact surface of a track part have a curvature having a constant difference .DELTA.K in relation to the curvature of the corresponding current contact surface of the wheel supported on it, or that successive contact surfaces of the track part and the wheel have a continually changing curvature difference .DELTA.K with the curvature difference between the contact surfaces of the track part and wheel lessening as the angle of contact tangent increases.
