Abstract

The utility model relates to hydraulic drive force, particularly a hydraulic drive energy ac amplifier of a manpower vehicle. The purpose is that great drive force is obtained through minor external force. The burden of a rider can be relieved. The primary structure is that a drive balance wheel and a piston are respectively assembled at a left end and a right end of a central shaft 16 for matching with an oil cylinder through an inner balance wheels 22, 21. A large oil cylinder and a small oil cylinder are connected through a guide pipe 13. The small oil cylinder on the right side of the central shaft exerts external force. The thrust of a large piston 11 is increased through the large oil cylinder. The thrust and pedal force synchronously drive a sprocket to rotate. The utility model which is suitable for bicycles and manpower tricycles has the advantage of simple structure. A vehicle speed can be increased 2-3 times through the amplified thrust.
