Abstract
An electrically motorized driving wheel for vehicles such as bicycles is provided. The electrically motorized wheel can include a wheel rim, a housing disposed inside and connected to the wheel rim, wherein the housing defines an installation space inside the housing, a driving force generating mechanism disposed in the installation space, and a driving force transfer mechanism connected to the driving force generating mechanism and configured to transfer a driving force generated from the driving force generating mechanism to the housing.
Claims20
A driving wheel for a vehicle, the driving wheel comprising:
- a wheel rim;
- a housing connected to the wheel rim, wherein the housing defines an installation space inside the housing;
- a driving force generating mechanism disposed in the installation space;
- and
- a driving force transfer mechanism connected to the driving force generating mechanism and configured to transfer a driving force generated from the driving force generating mechanism to the housing.
A driving unit configured to be detachably attached to a wheel rim for a vehicle, the driving unit comprising:
- a driving housing;
- a first motor for driving a first pinion gear located inside the driving housing and fixed to the driving housing;
- a second motor for driving a second pinion gear slantly facing the first pinion gear, located inside the driving housing and fixed to the driving housing;
- a third pinion gear located between the first and second motors, wherein the third pinion gear engages with the first and second pinion gears, and the combined driving force of the first and second pinion gears is applied to the third pinion gear;
- and
- a shaft fixed to the third pinion gear at the center of thereof and disposed perpendicularly to the axes of the first and second pinon gears,
- wherein the shaft and the third pinion gear are fixed to a frame of the vehicle, and
- wherein the driving housing including the first and second motors rotates with respect to the fixed shaft and the third pinion gear when the first and second pinion gears are driven by the first and second motors respectively.
