An omni-track system for mounting onto a wheel may include a plurality of track segments. Each of the plurality of track segments may include a male connector, a female connector, a roller mount, and at least one roller. The female connector may be arranged opposite the male connector. The roller mount may be fixedly secured to the track segment. The at least one roller may be rotatably secured to the roller mount. The plurality of track segments may be linked together to fully encompass an outer circumference of the wheel.

An omni-wheel may include a shaft, a plurality of rollers, and a braking device. The plurality of rollers may be circumferentially arranged about the shaft and arranged radially outward from the shaft. The braking device may include a fluid-filled bladder and a plurality of braking pads. The fluid-filled bladder may be circumferentially arranged about the shaft. The plurality of braking pads may be arranged between the fluid-filled bladder and the plurality of rollers. The fluid-filled bladder may expand radially outward when pressurized, displacing the plurality of braking pads radially outward to contact the plurality of rollers, preventing rotation of the rollers.

An omni-wheel including a hub, a plurality of rollers, and a braking system. The plurality of rollers are circumferentially arranged about the hub and arranged radially outward from the hub, where each roller of the plurality of rollers is secured to the hub by a roller mount. The braking system includes a first braking lever, having a first braking surface, pivotally secured to the roller mount, a second braking lever, having a second braking surface, pivotally secured to the roller mount, opposite the first braking lever, and an actuator arranged to rotate the first braking lever in a first rotational direction and the second braking lever in a second rotational direction. The first braking surface and the second braking surface contact at least one roller of the plurality of rollers when the first braking lever and the second braking lever are rotated by the actuator.

An omni-wheel may include a shaft, a plurality of rollers, and a braking device. The plurality of rollers may be circumferentially arranged about the shaft and arranged radially outward from the shaft. The braking device may include an at least one flexible clutch member, an at least one brake pad, and an actuator. The at least one flexible clutch member may have an outer diameter arranged about the shaft. The at least one brake pad may be arranged on the outer diameter of the at least one flexible clutch member. The actuator may be arranged to axially displace the at least one flexible clutch member. The at least one flexible clutch member may expand radially outward when axially displaced by the actuator, which may displace the at least one brake pad arranged on the outer diameter of the at least one flexible clutch member radially outward to contact at least one of the plurality of rollers, preventing rotation of the roller.

Embodiments of collapsible wheels and methods of making collapsible wheels are generally described herein. Other embodiments may be described and claimed.

Bicycle rims that allow tires to be more easily mounted in a tubeless configuration are disclosed. More specifically, a bicycle rim may control the two beads of the tire with separate bead channels for each bead and a center bridge extending between the two bead channels.

A wheel assembly that provides a simulated center lock wheel look that also enables exchanging of ornamental face plates with a center hub attachment device that will allow car enthusiasts to easily change the look of their automotive wheels while maintaining a center lock wheel appearance. The assembly includes three components: a base wheel, a plurality of ornamental face plates, and a center hub attachment extending from one of either the hub or the ornamental face plate.

A wheel is provided for a motor vehicle. The wheel includes a hub, a rim and a plurality of spokes that extend between the hub and the rim. At least one of the spokes includes an integral step having a slip resistant surface.

A track-width adjustment system, apparatus and method limit track-width adjustments in a self-propelled product applicator, according to a first speed-based protocol for track-width adjustments initiated by an operator of the applicator, and according to a second speed-based protocol for track-width adjustments initiated by an automatic track-width control arrangement of the applicator. An automatic track-width control arrangement continually monitors and adjusts track-width, as required to maintain a desired track-width at substantially any ground speed while the applicator is in motion. Operator initiated adjustments to track-width are allowed only within a prescribed range of ground speeds.

A mobile object is configured so as to be capable of moving front and rear bases 10,30 object to each other in order to make a wheel base provided between the front wheels 12 and the rear wheels 32 expandable and contractible. The front base 10 moves so as to be expand and contract the tread width between the front wheels 12 in association with the expansion and the contraction of the wheel base achieved. The seating part 41 is configured so as to turn forward in association with the relative movement of the front and rear bases 10,30 in order to contract the wheel base and the tread width. The seating part 41 is configured so as to turn backward in association with the relative movement of the front and rear bases 10,30 in order to expand the wheel base and the tread width.
