Abstract
A hydraulically damped motor mount for motor vehicles, and similar elastic supports having a controlled damping device, the free cross-sectional flow of which is statically closed off by a flexible diaphragm which is held with a certain freedom of movement between rigid support plates. In order to improve the acoustical behavior of such mountings, and to suppress the noise associated with the change in direction of the spring movements, the inner peripheral region of the support plates which embrace the diaphragm, and which overlap the edge of the latter, is provided with successive indentations in the form of gaps between teeth in such a way that the frictional forces generated by the approach of the diaphragm onto the support plates in the damping fluid is kept low. The inventive configuration of the support surfaces results in the elimination of undesirable tapping noises when the placement of the diaphragm has advanced partially.
