  • Publication number: 20190186586
    Abstract: The present invention relates to a bushing, preferably a hydraulic bushing, having an inner part, an outer part, at least one supporting spring which connects the inner part and the outer part radially to one another, and at least one stop element which is arranged between the inner part and the outer part, is connected to the inner part or the outer part, and is embodied in such a way that the stop element can limit the radial spring travel (D) between the inner part and the outer part in a predetermined fashion. The bushing is characterized in that the stop element is elastically connected to the inner part or to the outer part in such a way that the stop element can be elastically twisted relative to the inner part or relative to the outer part.

  • Patent number: 9784334
    Abstract: A hydromount (2) includes: a housing (4) and a compensating diaphragm (6), which enclose a hydraulic volume (8), a partition wall (12), which partitions the hydraulic volume (8) into a working chamber (14) and into a compensating chamber (16). The partition wall (12) contains a transfer channel (18), via which the two chambers (14, 16) are connected to one another, and wherein the partition wall (12) has an opening, in which there is a diaphragm or membrane (20) of flexible, elastomeric material clamped between two components (22, 24), wherein the diaphragm (20) is clamped between the two components (22, 24) in such a way that, as a result of the clamping, a radial pretension is produced in the diaphragm (20).
