ABSTRACT:
A hydraulically damping rubber sleeve spring containing two annular parts is disclosed. The parts are assembled axially, and each annular part has an inner support sleeve and an outer support sleeve surrounding the inner one with radial spacing, as well as a spring element made of an elastomeric material which connects the support sleeves. The annular parts are provided with at least two recesses, and are configured and assembled such that the recesses complement one another to form first and second fluid-filled working chambers. The chambers are sealed with respect to the environment and joined to one another, in a manner allowing fluid to pass, by at least one damping passage. The two spring elements of the annular parts are braceable against one another in such a way that the axial and radial spring stiffness can be adjusted separately from one another.
