A vehicle track drive module apparatus (10) is disclosed. The apparatus includes an upper drive sprocket wheel (12) connectable to a vehicle axle, a plurality of idler (14A, 14B) and bogey wheels, and an endless flexible rubber track (16) with spaced lugs (20) projecting from an inner track surface (18). The drive wheel (12) comprises a circular middle main plate (22) for connection to the axle and circumferentially spaced drive members (30). The drive members (30) project from the main plate (22) and extend axially either side of a middle position. A substantially flat rigidity ring (40) concentric with the main plate is affixed to the drive members (30) at inward end portions. The middle main plate (22) provides weight savings over the prior art and allows removal of material trapped between the track (16) and the wheel (12). |
