WHEEL HAVING ELECTRIC DRIVE MEANS
First Claim
1. A wheel equipped with an electrical drive unit, the wheel comprising:
- a stator having a plurality of windings about a central fixing shaft;
a rotor surrounding the stator while being spaced apart from the stator and having a plurality of magnets to rotate according to intensities of a current flowing through the windings;
a rim having a cylindrical shape, receiving the rotor and the stator therein, and provided at an outer peripheral portion thereof a tire;
a plurality of air guide protrusions formed in a circumference direction on outer and inner plates of the rim to allow air to be easily introduced;
a wheel speed sensor mounted on the stator to count a revolution number of the rotor;
a tire pressure sensor measuring an air pressure of the tire; and
a controller receiving sensor input values of a wheel, which are transmitted from a wheel speed sensor and a tire pressure sensor, through an Operation section and receives geographic and road information through a GPS receiver to control values of currents being supplied to the stator of each wheel.

Abstract
A wheel equipped with an electrical drive unit is provided. The wheel includes a stator having a plurality or windings about a central fixing shaft, a rotor surrounding the stator while being spaced apart from the stator and having a plurality of magnets, a rim having a cylindrical shape, receiving the rotor and the stator therein, a plurality of air guide protrusions formed in a circumference direction on outer and inner plates of the rim, a wheel speed sensor mounted on the stator, a tire pressure sensor measuring an air pressure of the tire, and a controller receiving sensor input values of a wheel through an operation section and receives geographic and road information through a GPS receiver. The steering and braking performance of the wheel equipped with the electrical drive unit are improved, so that the whole driving performance of the wheel is improved.
