Abstract
A driving device using pneumatic-hydraulic pressure as a power source for a vehicle has a pneumatic cylinder filled with high pressure air, a hydraulic cylinder filled with high pressure air and high pressure hydraulic fluid, a first supplementary cylinder, and a secondary supplementary cylinder. The hydraulic cylinder is connected with the pneumatic cylinder and is connected to the first supplementary cylinder and the secondary supplementary cylinder via a hydraulic motor. The first supplementary cylinder and the second supplementary cylinder are alternately pressurized, so as to alternately supply the pressurized hydraulic fluid to the hydraulic cylinder. Thus, the hydraulic cylinder can provide the pressurized hydraulic fluid with a pre-determined pressure to constantly drive the hydraulic motor. The driving device meets requirements of environmental protection from zero waste discharge.
