Patent ID: 7338037

Claim:
A rubber bearing comprising a bearing body implemented as an elastomer spring for damping oscillations introduced into the bearing in the axial direction (a) and/or in the radial direction (r), stop elements forming relative to at least one damping direction one or more path delimiters which restrict a spring travel of the bearing body in the corresponding damping direction, wherein the free travel of the elastomer spring is determined by the spacing (s) of stop faces of the corresponding stop elements which form the path delimiter in the corresponding direction, with the position of one of the stop elements being fixed on or in the bearing, whereas the position of another stop element that corresponds with the one stop element is fixed only relative to the elastomer spring and is movable with the spring during spring compression of the bearing body, and wherein at least in one damping direction, the limitation of the spring travel is adaptable during the operation of the bearing to the preload applied in the direction by releasing the position fix of one of the stop elements of the corresponding path delimiter, by changing the spacing (s) of its stop face from that of the corresponding stop element, and by again fixing the position of the corresponding stop element in its new position, whereby the position of the stop element can be changed by an actuator arranged on the bearing or by temporarily loosening a locking means and passively tracking the position of the stop element according to the preload, wherein at least one of the stop elements forming the path delimiter has an elastomer stop face, wherein the bearing is formed as an elastomer bush bearing with axial limit stops and comprises an inner section, the elastomer bearing body arranged concentric to the inner section, and an outer sleeve receiving the aforementioned parts and connected with the parts through vulcanization, and wherein the axial limit stops are arranged at one axial bearing end parallel to the bearing axis (L) and outside the outer sleeve, wherein stop elements are arranged on both sides of a radially outwardly extending fastening element, which is connected on this bearing end with a bearing body protruding from the bearing sleeve, the stop elements extending into a U-shaped stop element, so that each of the stop elements arranged on the fastening element and a corresponding one of the legs of a U-shaped stop element oriented transversely to the bearing axis (L) form a path delimiter, and wherein the axial position of the U-shaped stop element can be changed by temporarily releasing its position fix.
