  • Publication number: 20240123769
    Abstract: Segmented tires employ segments featuring cooperating recesses and protrusions at opposing sides thereof for mating of the segments with one another in the assembled tire body. Cleated tires with embedded cleats of greater rigidity than the tire body material provide improved traction in muddy or other slippery conditions while the compressible tire body smooths out the ride harshness of the tire. Mounting elements are also embedded within the segments of the tire body for secure mounting and reliable retention of the segments.

  • Publication number: 20170036482
    Abstract: A tireless steel wheel for a skid steer features a cylindrical drum, a set of cleats projecting externally from the drum, a hub plate inside the drum an at intermediate location between opposing ends thereof, frustoconical walls flaring outward from opposing sides of the hub plate toward the respective ends of the drum, and annular end plates joining the wider ends of the frustotonical walls to the drum at the opposing ends thereof. The hub plate is offset from an axial center of the drum, and the frustoconical walls are unequal to one another in their angle of taper. The annular walls prevent the wheels from digging into the ground, and the frustoconical walls prevent material accumulation inside the wheels. The offset position of the hub plate provides flexible mounting options to accommodate varying dimensional characteristics of different skid steer models and bucket sizes.
