Abstract: A transmission unit for a vehicle wheel which comprises an input shaft having an input pinion and, parallel thereto, an output shaft with an output gear wheel, where the input and output shafts are movable with respect to each other in a translatory manner. A planetary gear wheel meshes with the input pinion and the output gear wheel. The planetary gear wheel is supported on a planet carrier axle which is common to first and second planet carriers, the first planet carrier is coaxial to the input shaft and the second planet carrier is coaxial to the output shaft. The transmission unit permits the translatory decoupling between the input and the output drives with minimal construction space. It is possible, for example, to decouple wheel hub motors from the wheel suspension with respect to spring compression movements of the driven wheel, to reducing the unsprung masses of the wheel suspension.

Abstract: A transport vehicle wheel assembly comprising a set of rotating components and a set of static components wherein an applied electrical current applied to conductive material incorporated into at least one components structural matrix of one set of components gives rise to primary magnetic fields which interact with reactive magnetic fields associated with material incorporated into at least one components structural matrix of another set of components and gives rise to rotational forces which act on the rotating components of said transport vehicle wheel assembly to induce controlled forward rotation of a wheel and having regenerative braking and reverse drive ability thus allowing controlled retardation assistance.

Abstract: A wheel hub for capturing energy created by road bumps and converting that into energy to be used in moving a vehicle in it's current direction of motion. Energy return is accomplished by elastic spring means, although the physical principle of operation is not directly obvious. Any road shock imparted upon the wheel will result in a radial displacement of an outer wheel hub and thus a radial force toward the center of the wheel. The radial force will be released as an axial rotation imparted upon a wheel hub assembly, thus increasing the axial speed in the current direction of motion. The principle is similar to that causing the earth to rotate around the sun. The wheel hub assembly will not wobble erratically since there is a dampening component by virtue of a vehicles weight and moment of inertia of a rotating wheel. Additionally, total shock absorbtion, is increased.

Abstract: Embodiments of the pivot wheel assembly include a motor and a wheel. For example, a pallet may include a pivot wheel assembly at each corner, and each wheel is driven by its own motor. The pivot wheel assembly pivots and locks in the two 90 degree positions used for X and Y travel of the pallet. In some embodiments, each wheel assembly can be positioned in various positions in addition to the 90 degree positions. For example, the four wheel assemblies can be positioned to allow the entire pallet to rotate about its own center.

Abstract: An electrically motorized wheel assembly is provided which may be used in automotive vehicles. The wheel assembly is equipped with at least one electric motor having an output shaft located eccentrically from an axle of a wheel.

Abstract: A motor-driven wheel includes a wheel disc, a wheel hub, a knuckle, a hub bearing, a constant-velocity joint, an in-wheel motor, and a spring. The center of swing of the constant-velocity joint is placed closer to the outside of the vehicle relative to the hub bearing. Since such components of the constant-velocity joint as an inner race, balls and a cage are placed differently in position from the hub bearing, the hub bearing can be reduced in diameter. An outer race of the constant-velocity joint is integrated with the wheel hub into a single part and has an opening facing the outside of the vehicle. Since the opening is large and shallow, the work of installing the cage, balls and inner race and securing them with a snap ring is facilitated.

Abstract: A drive system base or platform, such as for a mobile robot, is disclosed having multiple caster wheels, each wheel having its own first motor for independent driving and its own second motor for independent steering. Each wheel is rotably and pivotably mounted in a separate wheel module, which includes both the driving and steering motors associated with the wheel. All of the wheel modules on the base are identical and interchangeable. The two motors of each module are mounted side by side in a vertical arrangement for compactness. Each wheel module includes a suspension for allowing each wheel to move vertically and independently relative to the base. The hub and tread of each wheel are each cast concentrically around a bevel drive gear in an offset manner to provide a wheel and bevel gear that turn more smoothly and precisely.

Abstract: A vehicle preferably having a wheel set convertible between driven and non-driven mode via clutch ring engagement/disengagement of the wheel hub and the axle. The clutch ring or other coupling component is readily replaceable in the field through manual removal of a removable cap enclosing said clutch ring or other coupling component, said coupling component exposed to the wheel exterior upon removal of the cap. The clutch ring or coupling component is designed to be the weakest link and to thereby fail upon excessive torque loading of the drive line before other drive line components fail and thereby enable in-field repair.

Abstract: An injection-molded plastic gear 1 as a molded gear includes a plurality of teeth 12 formed around an outer periphery of a rim, and a plurality of blades 8 formed at distances circumferentially on an inner peripheral surface of the rim 11 to produce an axial flow of air. A radially inner portion is formed on the side of inner peripheries of the blades 8 to support the rim 11 through the blades 8. When such injection-molded plastic gear 1 is rotated, the blades 8 produce an axial flow of air passed through holes 10 from the surface side to the back side. The flow of air can be blown to a part such as an IC, a motor and the like disposed adjacent the molded gear to cool it, and the heat of the teeth 12 and the rim 11 can be taken away by a heat transfer, whereby the teeth 12 and the rim 11 can be cooled. Thus, the injection-molded plastic gear 1 has a function as a cooling fan, whereby a forcible convection (flow of air) can be produced in a gear-accommodated space.
