20090288900 | Inverted pendulum mobile vehicle - Provided is an inverted pendulum mobile vehicle such as a single-passenger coaxial two-wheel vehicle which is capable of turning with a small turning radius without causing discomfort to a rider or a vehicle occupant or causing a cargo or the like on the vehicle from shifting or falling off from the vehicle. The vehicle comprises a wheel supporting frame ( | 11-26-2009 |
20100139996 | FRICTION DRIVE VEHICLE - In a frictional drive vehicle, a load acting on the vehicle such as the weight of a rider is converted into a force that urges two frictionally engaging parts ( | 06-10-2010 |
20110070997 | FRICTIONAL DRIVE DEVICE AND INVERTED PENDULUM TYPE VEHICLE USING THE SAME - In a frictional drive device comprising a pair of drive disks ( | 03-24-2011 |
20110209932 | OMNI-DIRECTIONAL VEHICLE - [Task] Provided is a vehicle that can make tight turns without significantly changing an attitude of a rider, and is highly convenient in narrow places. | 09-01-2011 |
20110233989 | WHEEL, AND FRICTION DRIVE DEVICE AND OMNI-DIRECTIONAL VEHICLE USING THE SAME - In a wheel for use in an omni-directional vehicle, gravel and other foreign matters are prevented from being trapped between free rollers forming the wheel, and traveling vibrations and noises are minimized at the same time. The wheel includes an annular member and a plurality of free rollers each rotatably supported by the annular member around a corresponding tangential line of the annular member, and a gap member is placed between each adjacent pair of the free rollers to fill a gap defined between the free rollers. | 09-29-2011 |
20110260523 | FRICTION DRIVE DEVICE AND OMNI-DIRECTIONAL VEHICLE USING THE SAME - In a friction drive device comprising first free rollers and second free rollers contacting each other at the outer circumferential surfaces thereof to frictionally transmit power from the second free rollers to the first free rollers, in order to minimize the slippage between the first and second free rollers, minimize the power loss and cause the first free rollers to move as designed, an outer peripheral part of each first free roller defining an outer circumferential surface thereof has a different stiffness from that of an outer peripheral part of each second free roller defining an outer circumferential surface thereof. | 10-27-2011 |
20120032496 | WHEEL, AND FRICTION DRIVE DEVICE AND OMNI-DIRECTIONAL VEHICLE USING THE SAME - [Task] To allow a wheel that provides a performance required for use in an omni-directional vehicle to be manufactured in an efficient manner. | 02-09-2012 |
20120061156 | FRICTION DRIVE DEVICE AND OMNI-DIRECTIONAL VEHICLE USING THE SAME - Heat generated by a drive source of a friction drive device such as an electric motor is allowed to efficiently dissipate to the atmosphere, and the friction drive device and an omni-directional vehicle using the same is designed in a highly compact manner. Left and right electric drive devices are placed on a central axial line of left and right rotatable drive members, and external teeth members serving as output members of the electric drive devices are directly connected to the respective rotatable drive members in a torque transmitting and heat transmitting relationship. | 03-15-2012 |
20120168235 | INVERTED PENDULUM TYPE VEHICLE - In an inverted pendulum type vehicle ( | 07-05-2012 |
