Document Type and Number:
WIPO Patent Application WO/2011/027967
Kind Code:
A2
Abstract:
Disclosed is a wheel having electric drive means, the wheel comprising: a stator consisting of a plurality of coils wound about a fixed shaft at the center thereof; a rotor configured so as to enclose a periphery of the stator with a gap therebetween, and having a plurality of magnets installed thereon, so as to rotate in accordance with the strength of the current flowing through the coils; a cylindrically shaped rim having the rotor and the stator disposed therein and a tire mounted on an outer periphery thereof; a plurality of air intake projections installed in a cylindrical configuration on an outer surface plate and an inner surface plate of the rim, so as to enable air to easily enter; a wheel speed sensor, installed on the stator, for counting the number of rotations of the rotor; a tire pressure sensor for measuring the air pressure of the tire; and a controller for receiving, via a computing unit, inputs of sensor input values for each wheel which are conveyed from the wheel speed sensor and tire pressure sensor, and receiving an input of geographical and road information through a GPS receiver, in order to control a current value supplied to the stator of each wheel. The wheel having electric drive means according to the present invention has improved steering performance and braking performance for improved overall driving performance.
