摘要:
In a frictional propulsion device comprising a main wheel including driven rollers (60) rotatably supported by an annular core member (32) about a tangential direction and a pair of drive disks (70) each carrying a plurality of drive rollers (78) 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 (78) at least partly engage the driven rollers (60), a diameter (D1) of a drive side contact circle is smaller than a diameter (D2) of a driven side contact circle, and the drive disks are vertically offset relative to the main wheel so that only those drive rollers adjoining the main wheel are in contact with the driven rollers.

Self balanced electric wheel optimized for dynamic stability suspension and damping functions in use, compactness and low weight when carried short learning step, low cost and liability.
摘要:
A usage detection system for a self-balancing powered unicycle is disclosed. The usage detection system is adapted to detect an indication of intended usage from a user and to provide an indication of intended usage. The indication of intended usage comprises manipulation of the overall unicycle device resulting from preparatory action taken by the user prior to the onset of the intended usage. Operation of the powered unicycle may thus be controlled based on an indication of intended usage from the usage detection system.
摘要:
A powered unicycle device, comprising: a single wheel; a motor adapted to drive the wheel; a balance control system adapted to maintain fore-aft balance of the unicycle device by controlling the motor; at least one foot platform for supporting a user of the unicycle device; and a casing comprising at least two casing portions adapted to be movable between a closed configuration, in which the outer rim of the wheel is substantially covered, and an open configuration, in which at least a portion of the outer rim of the wheel is exposed for contacting a ground surface.

In a frictional propulsion device comprising a frame (1), a main wheel (30) including driven rollers (60) rotatably supported by an annular core member (32) about a tangential direction and a pair of drive disks (70) each carrying drive rollers (78) 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 (78) at least partly engage the driven rollers (60), each drive disk includes, a hub (72) rotatably supported by the support shaft, a disk member (74) attached to a peripheral part of the hub, and holder beams (76) arranged circumferentially between the hub and the disk member such that each holder beam is attached to the hub at a first end (76A) thereof and to the disk member at a second end (76B) thereof, each drive roller being rotatably supported by a corresponding adjoining pair of holder beams.
