Abstract
A hydraulically damping bearing bush, particularly for motor vehicles, includes a hollow-cylindrical bearing core having ends with end surfaces and an outer tube having end surfaces. Two elastomeric support springs have a space therebetween and are disposed between the bearing core and the outer tube at the end surfaces. The support springs extend substantially radially and have inwardly curved wall portions. Elastomeric radial support lugs extend horizontally on two sides between the bearing core and the outer tube. The support lugs divide the space into upper and lower fluid-filled chambers. The chambers communicate with one another through an annular channel. A cylindrical diaphragm-like elastomeric part extends between the two support springs along the bearing core. The elastomeric support springs, support lugs and part are made as an integral molded and vulcanized part. Radially extending, bead-like stop rings are disposed on the ends of the bearing core in the vicinity of the inwardly curving wall portions.
