ABSTRACT:
A controllable motor bearing consisting of a journal bearing and a support which are connected parallel to one another by means of a first and a second spring element made of rubber. One of the spring elements can be locked in place by an auxiliary mechanism, if necessary. The first spring element is structured in the form of a ring, and has an inside diameter which is larger than the outside diameter of the second spring element. The first spring element overlaps the second spring element at least partially in the axial direction. The auxiliary mechanism consists of a support element which at least partially surrounds the second spring element at a radial distance. The second spring element has a recess which has an expanse and position in the axial direction which cooperates with the support element. A fluid medium can be fed into the recess. The second spring element can be expanded in the area of the recess, as a function of the pressure of the fluid medium, and can be placed against the support element so as not to move.
