Abstract
An engine mount includes upper and lower bearing plates and a hollow-cylindrical support spring being formed of an elastomer and being fastened between the bearing plates. A cup-shaped housing adjoins the lower bearing plate. An inner hollow chamber is defined by inner wall surfaces of the hollow-cylindrical support spring and of the cup-shaped housing. A transversely extending elastic wall divides the inner hollow chamber into an upper chamber and a lower chamber and has a periphery being clamped. A bolt extending centrally within the inner hollow chamber is joined to the upper bearing plate and to the transversely extending wall. The upper and lower chambers are filled with liquid for additional hydraulic damping, and the elastic wall has an overflow opening formed therein through which the upper and lower chambers communicate. A transversely-extending stop plate has an opening formed therein and is disposed in the cup-shaped housing. A control plate is elastically secured to the cup-shaped housing for controllable placement against the stop plate.
