摘要：
A centrifugal impellers structure is mounted to a transportation vehicle that has a wheel and a wheel hub and includes first and second centrifugal impellers. The first centrifugal impeller is in operative coupling with a free wheel hub axle mounted to the wheel hub and includes a top plate and a bottom plate, between which blades are mounted. The plates each form at least one inlet. The blades are arranged not to shield and block the inlets and define therebetween channels communicating with the inlets. The second centrifugal impeller is coupled to a rim of the wheel and includes a top plate and a bottom plate, between which blades are mounted. When the first and second centrifugal impellers are caused to rotate, the first centrifugal impeller generates an aerodynamic force that drives the second centrifugal impeller and the second centrifugal impeller generates a rotary force to drive the wheel.
