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 regulation device suitable for a magnetorheological damper. The damping regulation device comprises a magnetism isolation cover and a driving mechanism, wherein the magnetism isolation cover is arranged on a piston rod of the agnetorheological damper in a sleeving mode and located in a cylinder barrel of the agnetorheological damper, and the driving mechanism is used for providing driving force enabling the magnetism isolation cover to move axially along the piston rod. According to the damping regulation device suitable for the magnetorheological damper, the movable magnetism isolation cover is arranged in the cylinder barrel, and a magnetic field generated by a permanent magnet arranged on a piston assembly is shielded by regulating the position of the magnetism isolation cover; the nature of magnetorheological fluid is changed along with the change of the magnetic field, so that damping force of the damper is changed and damping regulation is achieved.

Description

Technical field [0001] The invention belongs to the technical field of dampers. Specifically, the invention relates to a damping adjustment device suitable for a magnetorheological damper. Background technique [0002] Car suspension is the general term for all the force-transmitting connection devices between the frame of the car and the axle or wheels. Its function is to transmit the force and moment acting between the wheel and the frame, and to buffer the transmission from the uneven road to the frame. Or the impact of the body, and attenuate the resulting vibration to ensure that the car can run smoothly. Car suspension performance is an important factor that affects car ride comfort, handling stability and driving speed. Therefore, studying car vibration, designing new suspension systems, and controlling vibration to the lowest level are important measures to improve the quality of modern cars. [0003] At present, the suspension system of automobiles usually adopts active o...
