The invention discloses an integrated-type electro-pneumatic execution unit, comprising a flow amplification valve, a conversion valve, a brake electromagnetic valve, a release electromagnetic valve and a conversion electromagnetic valve, wherein the flow amplification valve comprises a rubber diaphragm plate, a valve sleeve and a dual-rubber valve rod which are all arranged in a valve body; a template reset spring is arranged between the rubber diaphragm plate and the bottom part of the valve body; a valve rod reset spring is arranged between the dual-rubber valve rod and the top part of the valve body; the upper rubber valve core of the dual-rubber valve rod is matched with an inflation valve seat so as to form a control valve port A; the lower rubber valve core of the dual-rubber valve rod is matched with the upper end of the valve sleeve so as to form a control valve port B; the valve sleeve and the rubber diaphragm plate are connected together. The integrated-type electro-pneumatic execution unit can be conveniently installed between a distributing valve and an installation seat, and the backup function of the distributing valve can be reserved; a brake cylinder is controlled by the integrated-type electro-pneumatic execution unit by utilization of the conversion valve when the integrated-type electro-pneumatic execution unit is energized, and is controlled by a brake distributing valve when the integrated-type electro-pneumatic execution unit shuts off due to failure or is de-energized, therefore the safety and reliability for operation and control of vehicles are improved.
