A linear rigidity adjustable constant pressure type active suspension system in the technical field of automobile damping comprises a shell, a stator assembly, a rotor assembly, a main shaft, a sliding block, a spring, an eccentric wheel, a roller bearing, a planet wheel, an inner gear ring, a supporting frame, a coil, a rigidity adjusting piston, a composite shaft sleeve, a damping supporting piston, a protective sleeve, a base plate, a lower supporting arm rubber sleeve, a bottom sealing plate and main shaft end face teeth. The upper middle portion of the main shaft and the upper middle portion of the rigidity adjusting piston are both arranged in an inner cavity of the shell, the lower portion of the main shaft and the lower portion of the rigidity adjusting piston are both arranged in an inner cavity of the protective sleeve, the upper middle portion of the damping supporting piston is arranged in the inner cavity of the protective sleeve, and the bottom of the inner gear ring and the top of the rigidity adjusting piston are connected together through a lead screw structure. The bottom of the spindle and the top of the damping supporting piston are connected together through a lead screw structure. By means of the constant pressure function and the intelligent tire lifting function, suspension can be rapidly adjusted to be in the optimal state, and a driver and passengers can keep good comfort on various complex road surfaces.
