A wheel assembly includes a collapsible wheel and an airless flexible tire mounted on the wheel. The wheel includes a central portion and a plurality of circumferentially spaced mounting elements attached to the central portion. Each of the mounting elements is movable between a retracted position and an extended position, and may be pivotally attached to the central portion of the wheel and configured to pivot between the retracted position and the extended position. The tire may be positioned on the wheel when one or more of the mounting elements is in the retracted position, and the one or more mounting elements are moved to the extended position wherein the mounting elements engage and support the tire.

The present invention is provided with: a mounting body mounted on an axle; a ring-shaped body (13) surrounding the mounting body from an outside in a tire radial direction; a connecting member (15) configured to connect the mounting body and the ring-shaped body (13) such that the mounting body and the ring-shaped body (13) are displaceable; and a cylindrical tread member (16) mounted over the ring-shaped body (13), wherein grooves (51, 52) are formed at an outer peripheral surface of a portion located above and corresponding to a portion of the tread member (16) at which the ring-shaped body (13) and the connecting member (15) are connected.

An omnidirectional wheel includes a hub, a number of wheels, and a number of rubber covers. The hub defines a shaft hole passing through the hub. Each of the wheels is rotationally mounted on the hub and spaced around the shaft hole. Each of the rubber covers is sleeved on a corresponding one of the wheels and includes a three-dimensional pattern. The rubber covers prevent the hub from directly contacting the ground.

A method of manufacturing a spoke (12) for a non-pneumatic tire is provided that involves providing a first form (14) and a second form (16), where first and second components (18, 20) of the spoke are placed on the first form (14). A third component (22) of the spoke is placed on the second form (16). The first and second components are transferred to the second form (16). The first component, the second component, and the third component are transferred from the second form to a mold (48). Further, the first component, the second component, and the third component have heat and pressure applied thereto for curing.

The present invention relates generally to agricultural devices, and in particular, to a gauge wheel system for use in an agricultural device. In one aspect of the invention there is provided a gauge wheel for use on cultivation equipment comprising a hub member having a central bearing portion for mounting to the cultivation equipment; a peripheral flange portion displaced laterally with respect to the hub member; and a resilient coil member mounted to a surface of the hub member at a proximal end and comprising at least two windings that extend between the hub member and the peripheral flange portion to terminate at a free distal end adjacent the peripheral flange portion; wherein the free distal end of the resilient coil member is constrained to prevent contact of the resilient coil member with the peripheral flange portion.

A depth gauge wheel for a row planter. The depth gauge wheel sets the planting depth for the seeds planted by the row planter. The depth gauge wheel sets planting depth by setting the cutting depth of the disk opener of the row planter. The depth gauge wheel also scrapes mud from the disk blade of the disk opener. The depth gauge wheel includes a rim, a tire attached to the rim and a ring attached to the rim. The tire contacts the surface of the ground to set the cutting depth of the disk opener and the ring scrapes mud from the disk blade of the disk opener.

A laminate body of a rubber layer and a resin layer made of a resin, wherein the rubber layer includes a surface-treated superficial layer 4 directly united with the resin layer without any intervening adhesive layer.

The present disclosure relates to a method and manufacturing method for a tire tread composition having absorption properties with high electric conductivity and excellent wear resistance. Specifically, the present disclosure relates to the fabrication of a tire composition to be used as a non-pneumatic tire, the tire composition can be used as a mobile electrode with a water supply means that can identify the location of defects in the buried conductor using the tire electrode manufacturing with improved conductivity and contact resistance with the ground even though the tire compound has wear resistance by lowering the water swelling rate compared to the previous technology.
