Abstract
A wheel of a track system for traction of a vehicle (e.g., an agricultural vehicle) may be configured to protect a track of the track system by reducing stress induced in the track by the wheel. For example, a circumferential surface of the wheel may be uneven (e.g., curved) in a widthwise direction of the wheel (e.g., to have a crown) and/or a covering of the wheel may be asymmetrical about a midpoint of the covering in the widthwise direction of the wheel (e.g., include corners that are shaped differently).
Claims17
A wheel for a track system of a vehicle, the track system comprising a track-engaging assembly that includes the wheel and a track movable around the track-engaging assembly, the track being elastomeric to flex around the track-engaging assembly, the track comprising a ground-engaging outer surface for engaging the ground and an inner surface opposite to the ground-engaging outer surface, the wheel comprising:
- a body including a rim portion and a hub portion;
- a covering affixed to the body of the wheel;
- a first lateral side and a second lateral side opposed to one another;
- and
- a circumferential surface disposed between the first lateral side and the second lateral side and configured to contact the inner surface of the track, the covering including the circumferential surface and comprising:
- a first tapered portion tapered toward the first lateral side;
- a second tapered portion tapered toward the second lateral side;
- wherein the first and second tapered portions define an apex wherein a radial dimension of the wheel is maximal, the apex being centered in the widthwise direction of the wheel and is located in a central portion of the wheel.
A wheel for a track system of a vehicle, the track system comprising a track-engaging assembly that includes the wheel and a track movable around the track-engaging assembly, the track being elastomeric to flex around the track-engaging assembly, the track comprising a ground-engaging outer surface for engaging the ground and an inner surface opposite to the ground-engaging outer surface, the wheel comprising:
- a body including a rim portion and a hub portion;
- a covering affixed to the body of the wheel;
- a first lateral side and a second lateral side opposed to one another;
- and
- a circumferential surface disposed between the first lateral side and the second lateral side and configured to contact the inner surface of the track, the covering including the circumferential surface;
- wherein the covering comprises first and second portions made of different materials, the first and second portions being one of disposed one over another in a radial direction or one next to the other in the widthwise direction.

- a body including a rim portion and a hub portion;
- a covering affixed to the body of the wheel;
- a first lateral side and a second lateral side opposed to one another;
- and
- a circumferential surface disposed between the first lateral side and the second lateral side and configured to contact the inner surface of the track, the covering including the circumferential surface and comprising:
- a first tapered portion tapered toward the first lateral side;
- a second tapered portion tapered toward the second lateral side;
- wherein the first and second tapered portions define an apex wherein a radial dimension of the wheel is maximal,
- wherein a thickness of the covering varies in the widthwise direction of the wheel.
