Patent abstract
A tire wheel structure that avoids the adverse effect of the increase in the unsprung mass associated with the presence of a driving motor at the time of a road surface input to a tire wheel is provided. In the tire wheel structure, the driving motor is disposed near the tire wheel that is supported on a vehicle body. The driving motor drives the tire wheel by transferring driving force to the tire wheel. The output shaft of the driving motor is connected to a wheel of the tire wheel via a flexible coupling. The driving motor is supported by a knuckle member of a suspension via coil springs and absorbers so that the driving motor is relatively displaceable with respect to the tire wheel.
