Abstract
A two-chamber engine mount with hydraulic damping has a partition arranged between a working space and an equalization space. The partition is formed in a first subarea by a disc movable between stops. The play of the disc between the stops can be varied by a motor. In a second subarea, the partition is penetrated by a first choke canal. A second choke canal can be added to the first choke canal in series or parallel therewith by a motor.
Claims5
In a two-chamber engine mount having hydraulic damping comprising:
- means for defining a working space;
- means for defining an equilization space;
- partition means disposed between said working space and said equalization space, with said partition means having a first sub-area and a second sub-area;
- said first sub-area of said partition means being defined by first and second stops spaced from one another at a preselected distance;
- a disc member disposed and movable between said first and second stops;
- said second sub-area of said partition means being penetrated by a choke canal means having a length for providing choked liquid communication between said working space and said equalization space;
- the improvement comprising:
- motor means for varying said preselected distance between said first and second stops thereby varying the available movement of said disc member between said first and second stops;
- and
- motor actuated choke means in association with said choke canal means for varying the length of said choke canal means providing choked liquid communication between said working space and said equalization space.
