Flexible, reinforced vehicle track with anisotropic material for durability
A recently granted patent (Publication Number: US11999422B2) discloses a novel track design for vehicles, specifically designed to be mounted around a track-engaging assembly comprising multiple wheels. The track features an inner side with wheel-contacting projections and elastomeric material allowing flexibility around the assembly. The key innovation lies in the inclusion of cores within the elastomeric material, each core comprising a wheel engager and flexible wings that can deflect in different directions. These cores are made of materials with varying mechanical properties, allowing for anisotropic behavior and improved performance.
Furthermore, the patent claims detail various aspects of the core design, including the materials used, stiffness levels, and the incorporation of mechanical joints for variable stiffness during use. The inclusion of sensors to adjust the longitudinal stiffness of the core based on contact with objects is another notable feature. By enabling the track to adapt its stiffness dynamically, the design aims to enhance the vehicle's performance, particularly in challenging terrains where flexibility and traction are crucial. Overall, the patented track design represents a significant advancement in the field of vehicle tracks, offering improved durability, flexibility, and adaptability for various applications.
