Abstract
A hydraulically damped elastic engine mounting having a ring-shaped rubber spring member which takes up static and dynamic loads and is equipped with a damping disk immersed in a damping fluid in order to provide hydraulic damping. The damping disk is movably mounted with axial play between spherical or conical buffer surfaces, and is provided in the vicinity of the buffer surfaces with passages through which the damping fluid can flow. The free path of the disk governs the damping applied, and at the same time prevents undesirable impact noise by the special design of the parts which move in relation to each other. Moreover, the damping disk may be constructed in such a way that interfering cavitation phenomena produced in the two surfaces are suppressed. This ensures that the damping device is fully effective in all vibration ranges and under all conditions occurring while the vehicle is being driven. This may be effected by providing the damping disk with a large number of holes distributed over its entire surface, by making the damping disk star-shaped with several vanes, or by making the damping disk somewhat dish-shaped.
