A replacement endless drive track 11 for use on a heavy duty tracked vehicle such as a bulldozer or tank includes a reinforced polymeric drive belt 13, two parallel sets 17, 18 of closely spaced rail blocks adjacent the drive belt, a plurality of drive pins 19 extending between opposing ones of the rail blocks, and supporting members 20 adjoining the drive belt and the rail blocks. The rail blocks are substantially Z-shaped, such that a forward portion of one rail block is offset and overlaps the rearward portion of a directly adjacent rail block. The rail blocks 17, 18, drive pins 19 and drive treads 21 may be comprised of a polymeric material which is harder than the polymeric material of the drive belt 13. The drive pins 19 may alternatively be disposed at a lateral end of the supporting members 20 to accomodate a tracked vehicle with peripherally disposed drive sprockets. In addition, the frame of the tracked vehicle may be adapted to provide for attachment of widened rollers which roll directly on the track for smoother and quieter travel. <IMAGE> |
