Anti-roll and anti-pitching magneto-rheological oil-gas interconnection suspension system

Abstract

The invention discloses an anti-roll and anti-pitching magneto-rheological oil-gas interconnection suspension system which comprises dampers located on the left front portion, the right front portion, the left rear portion and the right rear portion of a suspension and used for adjusting the height of a vehicle and further comprises an interconnection structure for connecting the left front damper and the right rear damper and connecting the right front damper and the left rear damper. The damper comprises a main cylinder, a piston rod cylinder in sliding fit with the main cylinder and an auxiliary cylinder which are sequentially communicated, a top oil nozzle is arranged at the top of the piston rod cylinder, and a floating piston is arranged in the auxiliary cylinder and divides an inner cavity of the auxiliary cylinder into a hydraulic oil cavity and a magnetorheological fluid cavity. According to the invention, through the interconnection of the left front damper and the right rear damper as well as the interconnection of the right front damper and the left rear damper, the anti-roll and anti-pitching performance of the heavy-duty vehicle is improved, the viscosity of the magnetorheological fluid under the action of a magnetic field can be adjusted through electromagnetic control according to real-time road conditions, and the damping characteristic can be quickly adjusted.
