A track assembly suitable for use with a track laying vehicle. The pitch of the drive members (7) on the drive wheel (5) is different to the pitch of the transmission elements (11) of that section of the belt which is in engagement with the drive wheel (5) such that the maximum transmission force applied to the belt by the drive wheel (5) is at that section of the belt in engagement with the drive wheel (5) in the region where the belt leaves the drive wheel (5). One form of the drive wheel (5) comprises a hub, spaced apart outer rim sections (65) and a plurality of drive members (7) extending between the rim sections (65). The outer rim sections (65) and/or the drive members (7) include a rotatable belt contact surface portion (88, 89, respectively) which in use engage a belt or track of the track assembly. |
