Abstract
Hydraulically damping rubber engine mount comprising an inner tube (1) and an outer tube (2) surrounding the inner tube at a radial distance therefrom, the tubes being joined together by a rubber-elastic cushion (3) having two liquid-filled working chambers (4, 5) separated from one another by a dividing wall (6) capable of vibration and are joined to one another by at least one connecting passage (7). A gas-filled cavity (8) is disposed within the first working chamber (4) and defined by inflatable walls which have in at least a partial area an opening to the atmosphere and are surrounded at least partially by the working chamber.
Claims13
Hydraulically damping engine mount comprising
- an inner tube,
- an outer tube surrounding said inner tube at a radial distance therefrom,
- an elastomeric cushion between said inner tube and said outer tube, said cushion having therein first and second liquid filled working chambers which are hydraulically connected by a passage, said first and second liquid filled chambers lying between said inner tube and said outer tube,
- a vibratable dividing wall separating said first and second working chambers, and
- elastomerically deformable pocket means in said first working chamber, said pocket means defining therein a gas filled cavity which is open to atmosphere.
