Abstract: The mounting of an engine with at least one hydraulically damped spring element on the body of a motor vehicle having a wheel which is spring-mounted with respect to the body. Movements of the engine as a result of irregularities in its path are damped by a displacement transducer placed between the body and the wheel, and the hydraulically damped spring element is operatively connected to the displacement transducer in such a way that as the signal from the displacement transducer increases as a result of a change in displacement between the body and the wheel, the hydraulic damping of the spring element increases.

Abstract: An engine is mounted on a motor vehicle chassis with at least one rubber metal mount acted upon hydraulically to vary its spring rate under the control of a hydraulic control device. The motor vehicle have has at least one wheel mounted in a sprung fashion to the chassis and the engine displacement vibrations are minimized by a displacement transducer placed between the wheel and the chassis that signals the control device to hydraulically increase the spring rate of the engine mount with increasing displacement between the wheel and chassis in advance of wheel movement passed through the chassis affecting the engine in a predetermined frequency range.
