Abstract
A track attachment includes a track body forming a convex surface for facing a driving terrain and a concave surface for facing a wheel or tire, with at least one blade extending from the convex surface for increasing lateral traction of the wheel or tire. The at least one blade may be defined as an elongated shape extending in the direction of rotation of the wheel or tire to generate and increase in lateral traction. The track body and at least two blades may define a channel at the convex surface to generate a floating effect on soft and loose terrain. The track attachment may be provided with supporting ribs and openings for facilitating attachment to the wheel or tire. A traction system includes a plurality of track attachments secured to a wheel or tire.
Claims20
A track attachment for use with a wheel, the track attachment comprising:
- a track body extending in a longitudinal direction from a first end to a second end and in a lateral direction perpendicular to the longitudinal direction from a first side to a second side, the track body forming a convex surface and an opposing concave surface, the concave surface of the track body defining a longitudinal curve between the first end and the second end and a lateral curve between the first side and the second side, said lateral curve having a degree of curvature greater than a degree of curvature of said longitudinal curvature;
- and
- at least one blade having a base connected to the convex surface of the track body and an opposing edge spaced away from the track body, the at least one blade having a front end and a back end extending between the edge and the base, a first face and an opposing second face of the at least one blade extending between the edge and the base and also extending between the front end and the back end;
- wherein a minimum length of the at least one blade extending from the front end to the back end in the longitudinal direction is greater than a maximum thickness of the at least one blade extending from the first face to the second face in the lateral direction.
A track system comprising:
- a wheel including a lateral circumference around a tire and rim and a plurality of spokes;
- and
- a plurality of track attachments, each track attachment comprising:
- a track body extending in a longitudinal direction from a first end to a second end and in a lateral direction perpendicular to the longitudinal direction from a first side to a second side, the track body forming a convex surface and an opposing concave surface, the concave surface of the track body defining a longitudinal curve between the first end and the second end and a lateral curve between the first side and the second side, said lateral curve having a degree of curvature greater than a degree of curvature of said longitudinal curvature;
- and
- at least one blade having a base connected to the convex surface of the track body and an opposing edge spaced away from the track body, the at least one blade having a front end and a back end extending between the edge and the base, a first face and an opposing second face of the at least one blade extending between the edge and the base and also extending between the front end and the back end;
- wherein a minimum length of the at least one blade extending from the front end to the back end in the longitudinal direction is greater than a maximum thickness of the at least one blade extending from the first face to the second face in the lateral direction.
