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. A common valve plate is between the chambers. An uncoupling membrane of an elastic material is arranged in a cage structure with openings. The edge of the uncoupling membrane is inserted radially movably with a gentle pretension or clamping force in a recess between two disks of the valve plate, which are designed as a cage, wherein at least one of these openings is continued radially to the edge of the uncoupling membrane.
Claims19
An engine mount with hydraulic damping for motor vehicles, the mount comprising:
- a housing with partially elastically deformable walls, said housing defining first and second chambers;
- a damping fluid positioned in said first and second chambers;
- a valve plate positioned in said housing and forming a common wall of said first and second chambers, said valve plate including a cage and an elastic uncoupling membrane positioned inside said cage, said cage defining a plurality of fixed membrane openings, said cage contacting said uncoupling membrane in an area completely around said fixed membrane openings without axial clearance, said fixed membrane openings having an axial cross section tapering down in a direction away from said uncoupling membrane due to oblique limiting surfaces, said cage defining a passage opening having an edge continued radially to an outside edge of said uncoupling membrane for movement of said edge of said membrane into said passage opening and forming a channel between said first and second chambers during abruptly occurring differences in pressure between said first and second chambers.
An engine mount comprising:
- a housing with partially elastically deformable walls, said housing defining first and second chambers;
- a valve plate positioned in said housing and forming a common wall of said first and second chambers, said valve plate including a cage and an elastic uncoupling membrane positioned inside said cage, said cage defining a plurality of fixed membrane openings, said cage holding said uncoupling membrane in an area completely around and closing off said fixed membrane openings without axial clearance, said cage defining a passage opening having an edge positioned adjacent an edge of said membrane for movement of said edge of said membrane away from said edge of said passage opening and forming a channel between said first and second chambers.
An engine mount with hydraulic damping for motor vehicles, the mount comprising:
- a housing with partially elastically deformable walls, said housing defining first and second chambers;
- a damping fluid positioned in said first and second chambers;
- a valve plate positioned in said housing and forming it common wall of said first and second chambers, said valve plate including a cage and an elastic uncoupling membrane positioned inside said cage, said cage defining a plurality of fixed membrane openings, said cage contacting said uncoupling membrane in an area completely around said fixed membrane openings without axial clearance, said fixed membrane openings having an axial cross section tapering down in a direction away from said uncoupling membrane due to oblique limiting surfaces, said cage defining a passage opening having a limitation overlapping an outside edge of said uncoupling membrane for movement of said edge of said membrane into said passage opening and forming a channel between said first and second chambers during abruptly occurring differences in pressure between said first and second chambers.
