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.
Claims17
A segmented tire comprising:
- a resiliently radially-compressible non-pneumatic tire body having an outer circumference spanning circumferentially around a central rotational axis on which said tire body is rotatable, said tire body comprising a plurality of tire segments each made of a same molded material as one another and each spanning a respective partial circumferential distance around said central rotational axis, which denotes an axial direction of the tire;
- wherein:
- each segment comprises a first side facing a first circumferential direction around the rotational axis of the tire body and a second side facing an opposing second direction around the rotational axis, the first side having a recessed area therein and the second side having a protruding area thereon sized and shaped for mating with the recessed area in the first side of an adjacent one of the plurality of tire segments, and of which said first and second sides, including the recessed and protruding areas thereof, are all composed of said molded material of the segment;
- the recessed and protruding areas of adjacent segments mate together and block axial separation of said adjacent segments from one another in the axial direction;
- the recessed area of each segment reaches an outer surface thereof that defines a respective portion of the tire body's outer circumference so as to accommodate radial sliding of the adjacent tire segment into place during assembly of the tire body;
- each segment, at the outer surface thereof, comprises a plurality of raised treads, at which a radial thickness of the segment is greater than at unraised areas of the outer surface between said raised treads;
- and
- one of said treads of each segment occupies the protruding area at the second side of the segment, and said raised treads of each segment are discretely spaced from one another in the circumferential direction of the tire body throughout an entire axial span of said raised treads in the axial direction, and are thus entirely unconnected to one another at elevations of radially raised relation to said unraised areas between the raised treads.
