Abstract
The invention belongs to the field of vehicle parts and relates to a semi-active control type engine hydraulic mount based on a magneto-rheological elastomer. The semi-active control type engine hydraulic mount comprises a connecting stand, a main spring frame, a main spring, an expansion membrane, inertia passages, a magneto-rheological elastomeric decoupling membrane, an electromagnet, a shell and connecting bolts. The main spring frame is connected with the main spring in a vulcanization manner. A lower liquid chamber is composed of the magneto-rheological elastomeric decoupling membrane and the main spring. The upper liquid chamber is composed of the expansion membrane and the main spring. The upper liquid chamber is communicated with the lower liquid chamber through the inertia passages. The electromagnet is fixed on the shell. The semi-active control type engine hydraulic mount is simple in structure, the magneto-rheological elastomeric decoupling membrane is made of the magneto-rheological elastomer, and rigidity value of the decoupling membrane is controlled by changing magnetic induction intensity of the electromagnet, thus damping and denoising effect of the vehicle is achieved, the semi-active control type engine hydraulic mount is simple in structure, and a production method is simple.
