摘要： The invention relates a torsional vibration damper, comprising the following features: a primary part with two lateral discs (1, 2) which are connected to each other for conjoint rotation; a secondary part with a central disc (3) which is arranged between the lateral discs; a primary part and secondary part are rotationally connected to each other via springs (5); damping chambers which are filled with a damping medium and each have at least one throttle opening; guide elements (7.1) are provided for supporting and guiding the springs. The invention is characterized by the following features: each spring is assigned two guide elements which are both arranged at mutual axial distance and form the supporting surfaces against a movement of the spring in the radial and in the axial direction.

摘要： The invention relates to an elastic coupling in disc construction, in particular for damping torsional vibrations of an internal combustion engine, having the following features: a first coupling half, which comprises two side discs, which are connected in a rotationally-fixed manner on the outer circumference; a second coupling half, which is formed by at least one middle disc assigned to a hub, which is arranged between the side discs and enveloped thereby; the two coupling halves are pivotable to a limited extent to one another against the force of at least one elastic coupling element; the side discs delimit a liquid-tight inner space, which receives the middle disc, at least one damping chamber, which is variable in volume during the mutual pivoting of the coupling halves and is filled with a damping medium, is arranged in the radial outer area of the inner space; a floating damping ring, which is pivotable to a limited extent in relation to each of the two coupling halves, is introduced into the inner space, the damping ring forming at least one first partial chamber of the damping chamber with the first coupling half and forming at least one second partial chamber of the damping chamber with the second coupling half; the floating damping ring being divided over the circumference of the coupling into individual ring segments, which are separate from one another, and which are mounted to slide on the radial exterior on the middle disc and/or on the radial interior on an outer edge of at least one side disc. The elastic coupling according to the invention is characterized in the state which is not loaded in the peripheral direction by the damping medium or one of the two coupling halves, the ring segments, at one or both axial ends, have a predefined spacing in the radial direction of the coupling in relation to the middle disc and/or in relation to the outer edge of at least one side disc, and the ring segments are mounted in a bending or tilting manner on the middle disc and/or at least one side disc in such a manner that the predefined spacing at the axial end of the ring segments in relation to the middle disc and/or the outer edge of at least one side disc is bridged by bending or tilting in the state of the ring segments which is loaded in the peripheral direction by the damping medium or one of the two coupling halves.
