Abstract: A resilient mount is disclosed comprising a spring element retained between two mount retaining means and a controllable magnet fastened to one of the two mount retaining means. The magnet is adapted to cooperate with a magnetically responsive element to vary the spring characteristic of the resilient mount on a continuous basis with the magnetically responsive element fixed inside the spring element.

Abstract: In a motor vehicle, the drive unit is suspended on a transverse member resting on the wheel suspension struts of the vehicle. The suspension struts are secured to the vehicle body by means of a suspension mount which includes a damping block. The suspension mount has an inner portion connected with the suspension strut, an intermediate portion connected with the transverse member, and an outer portion connected with the vehicle body. The inner portion, the intermediate portion and the outer portion are joined to each other through a rubber member which is loaded, substantially, in shear.

Abstract: A motor vehicle engine mount is disclosed comprising a core of a solid material placed between two parts made of elastomeric material, each of which is connected to a rigid outer part attached to the engine or the chassis. The core is determined to vibrate at a frequency corresponding to that of the engine and in a direction substantially counter to the vibration of the engine and is shaped relative to the outer parts such that a reduction occurs in the distance separating it from the outer parts in one of the vibration directions, leading to an increase in the spring rate of the mounting arrangement.

Abstract: A mounting assembly has between an upper and a lower outer member, and between elastic members interconnected therewith, a core member made of a rigid material. The elastic members are formed and arranged in a manner to cause, upon application of an axial force onto the mounting assembly, rotational movement of the core member. On the core member, there are mounted a pair of pivotable flyweights adapted for divergent synchronous pivoting through larger or smaller angles. The arrangement enables the inertia moment of the core to be varied and the vibration attenuating characteristics of the mounting assembly to be adjusted accordingly. According to a preferable arrangement, the flyweights are adjusted by means of a servomotor.
