Abstract
A rubber sleeve spring having hydraulic damping includes an internal and an external tube 1, 2 which are radial-elastically supported on one another by means of a first spring body 3. A second spring body 10 is provided corresponding to the first spring body 3. The second spring body is disposed in the gap between the internal and the external tube 1, 2 at a radial distance to the first spring body 3. The second spring body 10 can optionally be connected to the internal and/or the external tube 1, 2.
Claims4
Elastomeric sleeve spring which has hydraulic damping, comprising:
- an internal tube and an external tube which are radial-elastically supported on one another;
- a first spring body made of elastomeric material for radial-elastically supporting said tubes;
- the first spring body including at least two opposing, liquid-filled chambers which are separated by a wall and connected in pairs by means of a damping opening;
- and
- second spring body means for substantially enclosing in an axial direction the first spring body and the second spring body means being disposed in a gap between the internal and external tubes and spaced apart at an axial distance from the first spring body and frictionally engaging the internal tube, in a stress-free state the second spring body means including two spring bodies each contacting the external tube in a stress-free state at only two contact locations in one direction of stress and in a stress-free state the second spring body means having different resiliences in two radial planes which are perpendicularly associated with one another.
