Problems solved by technology

[0003] At present, the suspension system of automobiles usually adopts active or passive suspension, but the spring stiffness and damping coefficient of passive suspension are not adjustable, and the vibration reduction effect is poor, which cannot meet the requirements of vehicle ride comfort and safety at the same time. Require
Although the control effect of the active suspension system is good, the structure is complex, the cost is high, and the energy consumption is large

Abstract

The invention discloses a damping-adjustable magnetorheological damper. The damping-adjustable magnetorheological damper comprises a cylinder barrel, a piston rod, a piston assembly and a damping adjusting device, wherein the piston assembly is arranged in the cylinder barrel, and is connected with the piston rod; the damping adjusting device comprises a magnetic separation cover coating the piston rod and positioned in the cylinder barrel, and a driving mechanism for providing driving force; and the driving force provided by the driving mechanism enables the magnetic separation cover to axially move along the piston so as to adjust the position of covering the piston assembly. The magnetorheological damper is provided with the movable magnetic separation cover in the cylinder barrel; a magnetic field of a permanent magnet arranged on the piston assembly is shielded through adjusting the position of the magnetic separation cover; and the property of magnetorheological liquid is changed through changing the magnetic field, so that the damping force of the damper is changed, and the damping adjusting purpose is achieved.

Description

technical field [0001] The invention belongs to the technical field of dampers, in particular, the invention relates to a magneto-rheological damper with adjustable damping. Background technique [0002] Automobile suspension is the general term for all force-transmitting connection devices between the frame of the car and the axle or wheels. Or the impact force of the car body, and attenuate the vibration caused by it, so as to ensure that the car can run smoothly. The performance of automobile suspension is an important factor affecting the ride comfort, handling stability and driving speed of automobiles. Therefore, studying automobile vibration, designing new suspension systems, and controlling vibration to the lowest level are important measures to improve the quality of modern automobiles. [0003] At present, the suspension system of automobiles usually adopts active or passive suspension, but the spring stiffness and damping coefficient of passive suspension are not...
