Abstract

The invention relates to a magnetorheological hydraulic rubber spring. The magnetorheological hydraulic rubber spring comprises an upper fixing sealplate, a lower fixing sealplate and a rubber external capsule, wherein magnetorheological liquid is filled into the rubber external capsule; the magnetorheological liquid is connected with a magnetorheological hydraulic regulation system; a height limitator is arranged on the lower fixing sealplate; an electromagnet and a coil are also arranged in the rubber external capsule; vibrating sensors are arranged on the upper and the lower fixing sealplates; and the vibrating sensors, the electromagnet and the coil are connected with a control unit module. Therefore, the magnetorheological hydraulic rubber spring solves the problem of regulating the height and rigidity automatically in real time, has the characteristics of high oil resistivity, wide regulating range, strong thermal adaptability, high response speed and the like, and has the simple structure, small volume and low cost; and the magnetorheological hydraulic rubber spring can be used for active suspension systems of automobiles, if being integrated with a magnetorheological damper, the magnetorheological hydraulic rubber spring can become the active suspension systems, which change the height, rigidity and damping automatically in real time, of the automobiles, and the magnetorheological hydraulic rubber spring can also be applied to other active vibration control systems.

Description

technical field [0001] The invention relates to a magneto-rheological hydraulic rubber spring, in particular to a magneto-rheological hydraulic rubber spring control system which can automatically change height and rigidity 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 (supporting force), longitudinal reaction force (traction 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 proper cooperation to ensure the stability of the car; 2. To en...
