omnidirectional wheel and being motorized vehicle that is equipped

The invention relates to a spherical wheel that can be driven by a motor, including a first body (1.1) and a second body (1.2) which are substantially hemispherical and mounted coaxially to one another so as to pivot about a support axle (2), the bodies being separated by an interstice (3) in which a shaft (6) extends, said shaft having an end that is rigidly connected to the support axle, and an opposite end that is connected to a drive motor, characterized in that at least one element (7, 17) extending at least one portion of the outer surface of the bodies extends into the interstice. The invention also relates to a vehicle comprising a chassis supported by such wheels.
