ABSTRACT:
Rubber sleeve spring with an hydraulic damping, including two connecting pieces which enclose one another in a relationship parallel to their axes and are radially spaced apart and, in which, in the gap formed by this space, there are two spring bodies successively disposed in radial direction and preferably made of a rubber elastic material of which the external spring body encloses liquid filled chambers with a basically cross-like configured profile. At least two chambers of the external spring body which are opposite to one another are connected via a dampening opening and an intermediate mass is provided between the external and the internal spring body. The intermediate mass comprises two opposing half shells 7.1, 7.2 associated with the vertical center plane of the external spring body 4 in a mirror-inverted relationship. The half shells 7.1, 7.2 and the external spring body 4 are permanently attached to each other and the internal spring body 3 is pressed into the free space which is enclosed by the half shells 7.1, 7.2 while the external spring body 4 is radially pressed together.
