Abstract

The invention relates to a magneto-rheological hydraulic rubber air spring, which comprises an upper fixed sealing plate, a lower fixed sealing plate and a rubber outer bag. Magneto-rheological liquid is filled in the rubber outer bag, a rubber bag is arranged in the rubber outer bag, the rubber bag is connected with the upper and lower fixed sealing plates, and the magneto-rheological liquid is connected with a magneto-rheological hydraulic adjusting system. The air spring solves the problem of automatically adjusting the height and the rigidity in real time, has the characteristics of high oil resistance, wide adjustment range, strong temperature adaptability, high response speed, simple structure, small volume and low cost, and can be used for an automobile active suspension system; and if the air spring is integrated with a magneto-rheological damper, the automobile active suspension system with real-time automatic variable height, variable rigidity and variable damping can be formed; and the air spring also can be applied to other vibrating active control systems.

Description

technical field [0001] The invention relates to a magneto-rheological hydraulic rubber air spring, in particular to a magneto-rheological hydraulic rubber spring control system that can automatically change height and stiffness in real time for an active suspension system of an automobile. Background technique [0002] Automobile suspension is the general term for all force transmission connection devices between the frame (or load-bearing body) and the axle (or wheel). It transmits the vertical force (support force), longitudinal reaction force (traction force and braking force) and lateral reaction force of the road surface on the wheel, as well as the moment caused by these reaction forces, to the frame (or load-bearing body) , to ensure the normal operation of the car. The function of the car suspension: 1. In the case of load changes, vehicle speed changes and driving turns, the wheels and the axis can be kept in a correct fit to ensure the stability of the car; 2. To ...
