Abstract

An engine mount with hydraulic damping for motor vehicles, which has at least two chambers, which are provided with at least partially elastically deformable walls in a housing and are filled with a damping fluid, and a common wall of the chambers with a valve plate, in which a cage with a decoupling diaphragm made of an elastically deformable material arranged in it is provided. This decoupling diaphragm includes a round disk with constant cross section and is arranged in the cage without axial clearance, at right angles to the common chamber. The openings of the cage have a cross section tapering in the outward direction from the decoupling diaphragm due to oblique limiting surfaces.

Dependent claims

An engine mount for motor vehicles, comprising a housing defining a hydraulic damping system including at least two chambers, said chambers have at least partially elastically deformable walls;

damping fluid disposed in said chambers;
a common wall in common to the at least two chambers, said common wall including a valve plate with a cage and a decoupling diaphragm formed of an elastically deformable material, arranged in said cage, said decoupling diaphragm being formed of a disk with a substantially constant cross section, said disk being disposed in said cage substantially without axial clearance, at a right angle to said common chamber wall, said cage having openings with a cross section tapering in an outward direction from said decoupling diaphragm, said tapering being formed by oblique limiting surfaces, said decoupling diaphragm having an edge inserted radially movable with a soft axial biasing force between two disks of said valve plate, said valve plate disks define said cage.
