A suspension automobile comprising an automobile body, wheels and a flow disturbing plate, the wheels connect the flow disturbing plate through connecting devices, and a fluid channel communicating with the outside is formed between the upper surface of the flow disturbing plate and a bottom shell of the automobile body; a power device used for driving the automobile is contained in the body and is suspended along with lift force generated by the body. The invention changes the common sense that the wheels bear all weight generated by the self-weight, loads, and gravitational acceleration of the automobiles when traveling; the body which exceeds 90% by weight of the automobile generates lift force to suspend, the wheels eliminate lift force; meanwhile, a novel propelling force source is found from fluid resistance; the suspension automobile can be driven by various energy including engines and clean energy, thus effectively reduce energy loss.

A power transmission system comprises a transmission device, and a power supply device which powers the transmission device, wherein the transmission device comprises a cavity having a body, covers, an inlet and an outlet; at least a pair of rotors and a gear set that are assembled in the cavity; and a transmission shaft pivotally connected with the pair of rotors and the gear set; the power supply device comprises a power equipment available for transmitting a working fluid; shaft adapters connected with the inlet and the outlet of the cavity; and a connecting pipe connected between the power equipment and the shaft adapter; the working fluid is transmitted by the connecting pipe from the power equipment to the inlet of the cavity to provide the pair of rotors with normal force for radial motion in a reverse rotation direction and make pressure in the cavity increased.
