Abstract
A drive track is for a wheel train for mobilizing a paving vehicle upon a ground surface, the wheel train including a drive wheel and a bogie wheel. The track includes an endless body disposable about the wheel train and having a driven portion engageable by the drive wheel such that the drive wheel circulates the track about the wheel train. A generally annular rail portion is connected with the drive portion and has a continuous inner circumferential surface contactable with the bogie wheel, such that the bogie wheel rolls along the inner surface, and a continuous outer circumferential surface contactable with the ground surface. The rail portion supports the bogie wheel above the ground surface such that when the track circulates about the wheel train, a distance between the bogie wheel axis and the ground surface remains substantially constant as the bogie wheel rolls along the rail inner surface.
