A multidirectional wheel for traversing a surface is provided that includes a magnet and a plurality of rollers disposed around an outer periphery of each of the hubs of the wheels. The rollers are mounted for rotation in a second axial direction that is perpendicular to a first axial direction of the wheel. The rollers are supported by a plurality of magnetically-inducible brackets attached to the hub. The brackets are optimally sized and shaped to reduce the space between the magnetized materials of the wheel and the surface upon which the wheel travels.

The disclosure provides a wheel for an omnidirectional moving device which takes fewer man-hours for manufacturing, and a manufacturing method of the wheel for an omnidirectional moving device which takes fewer man-hours. The wheel includes an annular core body 36; a plurality of bearings 75 each including an inner ring 76 and an outer ring 77 relatively rotatable with respect to the inner ring, and the inner ring being fixed to an outer peripheral surface of the core body; and a plurality of rollers 37 each fixed to the outer ring and rotatably supported by the core body via the bearing. The inner ring is tightened and fitted to the core body.

A wheel for an omnidirectional moving device includes an annular core body formed by connecting joint members in an annular shape, and free rollers rotatably supported by the core body. Each of the joint members includes a shaft portion having a first end and a second end, a first connecting portion provided at the first end, and a second connecting portion provided at the second end. Each of the free rollers is rotatably supported by the shaft portion of the corresponding joint member. The first connecting portion of each of the joint members is rotatably connected to the second connecting portion of the adjacent joint member. The first end of each of the joint members abuts on the second end of the adjacent joint member so that a rotation range of the adjacent joint members is restricted. A cushioning material is provided between the first end and the second end.

In a frictional propulsion device comprising a frame, a main wheel including driven rollers rotatably supported by an annular core member about a tangential direction and a pair of drive disks each carrying drive rollers rotatable about a rotational center line at an angle with respect to both a tangential line of the drive disk and the rotational center line of the drive disk such that the drive rollers at least partly engage the driven rollers, each drive disk includes a hub rotatably supported by the support shaft, a disk member attached to a peripheral part of the hub, and holder beams arranged circumferentially between the hub and the disk member such that each holder beam is attached to the hub at a first end thereof and to the disk member at a second end thereof, each drive roller being rotatably supported by a corresponding adjoining pair of holder beams.

An aircraft hubcap/wheel cover which uses ambient airflow (120 mph-175 mph) to rotate wheels on the landing gear of an aircraft accomplished by using slightly protruding slats, blades, scoops or other air capturing shapes, (once the landing gear has been lowered). These air capturing shapes are integrated as part of the hubcap/wheel cover during manufacture and are directly determined by ground speed applicable to that aircraft with the ultimate purpose being tire longevity. The wheel cover hubcap is a single piece design and has no moving parts.

Holonomic bases, and drive shafts and roller assemblies that can be used in the holonomic bases. In some implementations, a holonomic base includes at least two pairs of roller assemblies, with each of the pairs being coupled to a corresponding drive shaft. In some of those implementations, each of the roller assemblies of each pair includes three roller segments that are each coupled to the corresponding drive shaft and that each include an exposed outward facing spherical zone that approximates a portion of the surface of a sphere. The roller segments of each roller assembly are in fixed relation to one another relative to the rotational axis of a drive shaft to which the roller assembly is coupled, but the roller segments each freely rotate about a corresponding roller segment rotational axis that extends outward from the drive shaft.

A multi-wheel system that minimizes wheel interactions with discontinuous and uneven surfaces. The multi-wheel system comprises wheels of varying diameters connecting to a rotating arm configured to raise and lower the wheels in response to obstacles along the rolling surface.
