Spring function component for a hydroelastic bearing

A hydroelastic bearing comprising:

• an outer sleeve;
• and
• a spring function component comprising:
• an inner mounting connection;
• an outer mounting connection that radially encircles the inner mounting connection;
• and
• a spring body that flexibly connects the inner mounting connection and the outer mounting connection with each other;
• wherein the outer mounting connection is installed in the outer sleeve, and wherein the spring function component is configured such that in an assembled state of the outer mounting connection:
• the spring body at least partly forms a boundary between two working chambers configured to hold a damping fluid;
• at least one choke channel is formed that hydraulically connects the working chambers to each other;
• and
• in addition to the choke channel there is at least one pressure relief valve configured so that when a specific pressure differential between the working chambers is exceeded, the at least one pressure relief valve opens and hydraulically connects the working chambers, wherein the at least one pressure relief valve comprises:
• at least one valve port located on an outer surface of the outer mounting connection and between the working chambers;
• and
• at least one valve crosspiece located in the valve port and configured to close the at least one valve port until the specific pressure differential is exceeded;
• wherein the at least one valve crosspiece, in a pre-assembled state of the outer mounting connection, has a cross section that tapers radially outward such that a radially outer tip of the at least one valve crosspiece projects by an overhang length beyond an envelope contour of the outer sleeve;
• and
• wherein the at least one valve crosspiece, in the assembled state of the outer mounting connection, has a bent area in which the radially outer tip is bent by the outer sleeve in a pre-determinable direction of flow of the at least one valve port.

A method of assembling a hydroelastic bearing, the method comprising:

• providing an outer sleeve;
• and
• inserting a spring function component into the outer sleeve, the spring function component including an inner mounting connection, an outer mounting connection that radially encircles the inner mounting connection, and a spring body that flexibly connects the inner mounting connection and the outer mounting connection with each other;
• wherein the outer mounting connection forms at least one pressure relief valve with the outer sleeve, the pressure relief valve including at least one valve port and at least one valve crosspiece located in the valve port, the at least one valve crosspiece having a cross section that tapers radially outward such that, prior to inserting the spring function component into the outer sleeve, a radially outer tip of the at least one valve crosspiece projects by an overhang length beyond an envelope contour of the outer sleeve.
