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

Abstract

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 outer cylinder. Magnetism isolation rings are arranged on the coil stop blocks, and coils are arranged at the outer portions of the magnetism isolation rings. A lower magnetism isolation plate is arranged between the bottom of the inner cylinder and the lower end cover, and a lower magnetism isolation plate is arranged between the bottom of the outer cylinder and the lower end cover. Second positioning bolts penetrate the lower end cover and the lower magnetism isolation plates to be connected with lower stop blocks of the piston. A guiding pipe is arranged on the wall of the outer cylinder and connected with the bottom of an air cylinder body, and an air cylinder piston is arranged in the air cylinder body. The upper portion of the inner cylinder communicates with the upper portion of the outer cylinder, and the lower portion of the inner cylinder communicates with the lower portion of the outer cylinder. The single-piston-rod, double-cylinder and double-coil magneto-rheological absorber has the beneficial effect that the need of automobile smoothness and operation stability for damping force of the absorber is taken into full consideration.

Description

technical field [0001] The invention belongs to the technical field of shock absorbers, and in particular relates to a magneto-rheological shock absorber with a single rod, double cylinders and double coils. Background technique [0002] With the gradual improvement of people's living standards, people put forward higher requirements for the comfort and stability of vehicles. Therefore, good vehicle ride comfort and excellent handling stability have become important performances that must be considered in current vehicle design. [0003] The main function of the automobile suspension system is to weaken the vibration from different road surfaces, improve the ride comfort of the vehicle, and improve the handling stability of the vehicle. The stiffness and damping coefficient of the traditional passive suspension will not be actively adjusted according to the change of the driving surface of the car, and cannot fully meet the vibration reduction requirements of the car under v...
