Abstract

The invention relates to an interconnected ISD suspension and system with adjustable damping and inertial capacity, which includes an accumulator, a cylinder, a piston, a piston rod, a connecting pipeline, a magnetorheological fluid, a switch valve and a magnetorheological conductor. The invention utilizes the continuous and reversible magnetorheological effect produced by the magnetorheological fluid under the action of an external magnetic field and the inertial effect produced by the flow of the magnetorheological fluid in the pipeline to change the diameter of the pipeline and control the applied The magnetic field changes the viscosity of magnetorheological fluid to realize the dynamic adjustment of inertial capacity and damping. The invention integrates the interconnection technology into the suspension system, not only realizes the interconnection of the left and right side suspensions through the magneto-rheological device, adjusts the roll characteristics of the vehicle during driving, but also dynamically adjusts the damping and inertial capacity of the suspension according to the driving state, further Improve vehicle driving performance.

Description

technical field [0001] The invention relates to an interconnected suspension system, in particular to an interconnected ISD suspension system with a magneto-rheological inertial vessel. Background technique [0002] During the development of the automobile industry, the suspension control technology is not limited to the control of damping and vertical stiffness, but also considers the stiffness of pitch and roll. In the past, the roll stiffness of the vehicle was mainly improved by installing active stabilizer bars or increasing the stiffness of the suspension, while the improvement of the pitch stiffness was also achieved by increasing the stiffness of the suspension; increasing the stiffness of the suspension can directly improve the performance of vehicle roll and pitch , but too high suspension stiffness will greatly reduce the ride comfort, and the installation of active stabilizer bar will have the disadvantages of high cost, complicated structure and affecting the ro...
