  • Track and track assembly for a track laying vehicle
    Patent number: 6869153
    Abstract: A track assembly for moving a vehicle which includes a track having lugs including both drive and guide portions on its inner surface. The guide portions substantially abut against the track rollers of the assembly. Such abutment maintains alignment of the track between those rollers so as to prevent it from moving from side to side and interfering with feeding of the drive portions onto the assembly drive sprocket. Further, the guide portions grab against the drive sprocket to maintain contact of the drive portions therewith. Each of the above functions permits uninterrupted movement of the vehicle since the track is enabled to move in a continued path.
