Single-piston-rod, double-cylinder and double-coil magneto-rheological absorber

The invention belongs to a single-piston-rod, double-cylinder and double-coil magneto-rheological absorber. The single-piston-rod, double-cylinder and double-coil magneto-rheological absorber comprises an upper hanging ring with a hanging ring lining assembly. The upper hanging ring is connected with a piston through a piston rod. The outer portion of an inner cylinder is sleeved with an outer cylinder. An upper end cover is arranged at the upper portion of the outer cylinder, and a lower end cover is arranged at the lower portion of the outer cylinder. An upper magnetism isolation plate is arranged between the top of the inner cylinder and the upper end cover, and an upper magnetism isolation plate is arranged between the top of the outer cylinder and the upper end cover. First positioning bolts penetrate the upper magnetism isolation plates and are connected with upper stop blocks of the piston. Bosses clamping coil stop blocks are formed on the side walls of the upper portion and the lower portion of the o
