Abstract

The present application relates to an airless flexible tire. The present application also relates to a wheel assembly comprising an airless flexible tire. The airless flexible tire includes a belt, drive lugs, and traction lugs. Drive lugs extend inwardly from the belt and form annularly spaced rigid high torque points. The traction lugs extend outwardly from the belt and are annularly offset from the drive lugs to form flexible sections that deflect radially inward when the tire engages the ground. Each traction lug has a size based on its actual height, the angle at which the traction lug extends relative to the radial axis, the angle of the distal surface of the traction lug, and the amount by which the tire deflects radially inward in the vicinity of the traction lug. effective height to at least partially equalize the rolling radii of the wheels to reduce the torque generated near the high torque point.

Description

technical field [0001] The present application relates to the field of transportation technology, and more particularly to an airless flexible tire and wheel assembly having a torque reducing tread pattern. Background technique [0002] Mobile agricultural irrigation systems such as center pivot systems and linear systems are commonly used to irrigate large fields and typically include conduits extending across several irrigation bridges. Each irrigation span supports a section of conduit elevated on a support tower that includes a wheel assembly configured to move the conduit across a field along a ground passage path. The wheel assemblies may include conventional pneumatic tires or "airless" tires. In the airless tire embodiment, the wheel assembly typically includes a rigid wheel and an airless flexible tire mounted on the rigid wheel. Rigid wheels have outwardly projecting spokes spaced apart to form polygonal or other non-circular shapes. The airless flexible tire ha...
