Title:
GRAVITY DRIVING WHEEL
Document Type and Number:
WIPO Patent Application WO/2008/046344
Kind Code:
A1
Abstract:
A gravity driving wheel can drive the vehicle by transferring the gravity of the vehicle
into power. The gravity driving wheel is formed in the wheel of the vehicle. A power
wheel and at least two virtual restricting wheels are provided inside the vehicle
wheel. A force picking device and a hydraulic system is provided on the power wheel.
The force picking device picks up the gravity loaded on the vehicle wheel and transmits
it to the hydraulic system. The hydraulic system generates the hydraulic power
and transfers it into the torque of the power wheel. Simultaneously the power
wheel, the force picking device and the rim of the vehicle wheel constitute the
internal and external transmission, so as to generate a roll assistant force when
the power wheel is picking up the gravity and generating the roll resistance. The
roll assistant force is equal to the roll resistance.
