Electrical double energy automobile linkage power

The invention provides an electrical double energy automobile linkage power. When a running automobile is driven by a battery pack, a power, inertia power is generated; a hydraulic motor is driven by a hydraulic pump with the inertia power as a driving force; the hydraulic motor provides power for a mute air compressor through a gearshift speed increaser; the mute air compressor produces compressed air and provides the compressed air for an air container for storing gas energy; air pressure control is used for controlling the gas pressure setting in the air container; a transfer switch and a double driving connection are controlled by the air pressure control; the double connection is set through the air pressure control to be automatically separated from and connected with a pneumatic motor and a DC motor; the inertia power connection is realized by providing power for the hydraulic pump and the DC generator with the inertia power generated during the running of the automobile; the transfer switch is control
