Abstract
The tracks of the present invention utilize cut pieces of reinforcement which are associated with each individual drive lug. By using individual pieces the lugs can be easily built up with multiple layers of rubber and reinforcement. The cut pieces can be strategically shaped and placed to optimize their effect to realize improved performance and durability of the track. Incorporation of such inner fabric reinforcement layers adds stiffness to the lugs and thereby increases the torque capacity of the track. Additional layers also provide increased damage resistance after the outer layers of fabric are worn away, and added layers improve wear resistance on the sides of the lugs due to undercarriage misalignment and track-to-wheel contact when the vehicle turns during normal operations.
