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.

A convertible scooter and crutch assembly is provided that is comprised of a front assembly and rear assembly. The front assembly is preferably pivotably, rotatably or equivalently interconnected to the rear assembly. In a first configuration, the convertible scooter is configured as a scooter that employs a handlebar, wheels, and a knee rest. In a second configuration, the front assembly and rear assembly is aligned in a liner manner to form a crutch. The convertible scooter is easy to manipulate, store and use.

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.

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.

The present invention provides a system and method for providing drive shaft braking for an irrigation machine. According to an exemplary preferred embodiment, the present invention includes a system for providing drive shaft braking during the operation of an irrigation machine where the irrigation machine includes a drive system having a drive motor and a drive shaft. According to a preferred embodiment, the system in accordance with the present invention preferably includes a cam attached to the drive shaft, an extension arm having a first securing point, a securing arm having a second securing point and a spring attached between the first securing point and the second securing point. According to a further preferred embodiment, the system of the present invention preferably further includes a follower mechanism secured to the extension arm, which applies continual frictional pressure to the drive shaft in response to the force applied by the spring to the follower through the extension arm. According to a further preferred embodiment, an exemplary system according to the present invention functions to hold the drive shaft in place when rotational force is not actively applied to the drive shaft by the drive motor.
