Abstract:
Hydraulic bearing comprising: a load-side connection; an axially opposed chassis-side connection; a spring element located between the load-side connection and the chassis-side connection and comprising an elastomer spring acting as an expansion bladder and a radial spring, and an axially extending helical spring acting as an axial supporting spring; a housing radially enveloping said spring element of the bearing and resting on a chassis; and a hydraulic damping system located between the load-side connection and the chassis-side connection comprising a working chamber, a throttling channel and an equalising chamber, the radial spring and the expansion bladder constituting two spring systems formed as separate elastomer components, the radial spring and the expansion bladder being connected at a load side of the supporting spring by coupling pieces which are rigidly connected with each other in a force-locking or form-locking way, the expansion bladder being connected to the housing, a metallic sleeve connected with the supporting spring and acting as one of the coupling pieces, said metallic sleeve being integrally formed with an annular flange, which is clamped between the helical spring and another of the coupling pieces of the radial spring, and being provided with a threaded inner bore opening at its load-side for connecting the load, wherein the annular flange engages a complementary recess of a bell-shaped apron of the expansion bladder.
