Walking Wheel For Off-Road Vehicles And Trucks
The walking wheel can be well used in trucks too for fuel economy, because it has lower rolling resistance on road compared with pneumatic tires. This is obvious, because rolling here takes place between metal wheel (bearing) and metal surface of the grip. Though there are also sliding frictional and rubber compression/decompression losses here, but they are insignificant compared with tire rolling losses. Besides, additional tractive effort of this mover will contribute to safety of trucks.
