A stator unit having slots and teeth secured to the axle is inward of said rotor to define a clearance gap therewith such that the rotor unit is rotatable about the stator core. An arrangement of coils is wound around the teeth of the stator unit, the coils adapted to be powered to induce a rotation of the rotor unit relative to the stator unit. A structure comprises hub portions rotatably mounted to the axle, the structure having lateral walls defining an inner volume for the rotor unit and the stator unit, the structure supporting the rotor unit. The structure comprises attachment members connected to spokes of the motorized wheel, located radially inward of the clearance gap between the rotor unit and the stator unit. | 03-24-2016 |
| 20160114677 | MOTOR-GEAR UNIT AS WELL AS WHEEL-HUB DRIVE HAVING SUCH A MOTOR-GEAR UNIT - A motor-gear unit is provided, including a motor, preferably an electric motor, having a first and second drive direction, a gear unit which is situated directly on the motor and includes an input shaft and a driven shaft as well as a controller, which is set up to drive the motor in the first and second drive direction, the gear unit having a first gear stage and a second gear stage, which feature different gear ratios, the first gear stage having a first freewheel and the second gear stage having a second freewheel, and a freewheel direction and a blocking direction of the first freewheel and the second freewheel are different. | 04-28-2016 |
| 20160121709 | IN-WHEEL DRIVE APPARATUS - An in-wheel drive apparatus includes a motor housing, a rotor, a rotor shaft, and a hub. The motor housing is supported in a wheel of the in-wheel drive apparatus. The rotor is rotatably supported in the motor housing. The rotor shaft protrudes from the rotor and is configured to rotate with the rotor. The hub is rotatably coupled to the motor housing. The hub is coupled to the rotor shaft. A rotational force of the rotor rotates the wheel via the hub. | 05-05-2016 |

| 20160144709 | ROLLER HAVING A DRIVEN WHEEL, LOAD TRUCK COMPRISING A ROLLER HAVING A DRIVEN WHEEL AND OPERATING DEVICE - A wheel of a roller includes a roller axis, the wheel being driven by an electric motor, wherein the electric motor is a hub motor which drives a hub body, which extends with circumferential. spacing and surrounds the wheel axle, relative to the fixed wheel axle, wherein furthermore the wheel has a running surface. The running surface is formed on a running surface carrier and the running surface carrier is supported flush on the hub body at the back of the running surface. Further, a manually movable load truck includes one or more rollers, of which at least one roller has a driven wheel. Further, an operating device, in particular for a manually movable load truck, is formed having a substantially annular cross-section having a central through opening. | 05-26-2016 |
