Cuboidal flexible bearing

摘要

The invention relates to cuboidal flexible bearings for vibration insulation, in particular between various units of a structure, which are loaded in a main-force direction and in a secondary-force direction and are constructed, in a composite manner, predominantly of rubber or a similar flexible material with rigid inserts. A preferred application area of such bearings is the flexible suspension of the permanent way of underground lines with respect to foundations anchored in the ground. In order, with good utilisation of construction area and without increasing the number and complexity of the supports, to provide cuboidal flexible bearings with force-introduction surfaces perpendicular to the main-force direction, with rigid inserts and with a ratio of shear strength to compressive strength of greater than 20%, the invention proposes that the rigid inserts be designed as steel bows with two parallel legs which extend parallel to the longitudinal direction of the bearing and perpendicularly to the main-force direction, the plane defined by these two parallel legs lying obliquely at an acute angle with respect to the main-force direction and the two parallel legs being connected to one another by at least one rigid web.
