Embodiment Construction

[0080] for example, figure 1 and figure 2 Different embodiments of the torsional vibration damper 1 are each shown in the schematic diagrams, which, for the sake of clarity, are generally described in the same manner and to some extent cross-referenced to the descriptions of the corresponding figures of the same components . Here, the annular disk forms the input side 4 . In the center of the common axis of rotation 2 a further disk element is designed, for example, as an output side 5 . Alternatively, the annular disc is the output side 5 and the disc element is the input side 4 . The above-mentioned variants are described below, where the terms are interchangeable.

[0081] As indicated by the arrows, traction torque 45 may be transferred from input side 4 to output side 5 and thrust torque 46 may be transferred from output side 5 to input side 4 . In one embodiment, the torque directions are set in opposite directions.

[0082]Interposed between the input side 4 and ...

Abstract

The invention relates to a torsional vibration damper (1) with a rotational axis (2) for a powertrain, having at least the following components: - an input side (4); - an output side (5); - one or more intermediate elements (6, 7, 8) which are connected between the input side (4) and the output side (5) so as to transmit a torque; - a first rolling body (9) and a second rolling body (10) for each intermediate element (6, 7, 8), wherein the at least one intermediate element (6, 7, 8) has a respective transmission path (11, 12) for rolling the rolling body (9, 10), and the input side (4) and the output side (5) have a counter path (13, 14) which complements the respective transmission path (11, 12); and - a number of energy storage elements (15, 16, 17) which corresponds to the number of intermediate elements and by means of which each intermediate element (6, 7, 8) paired with the respective energy storage element (15, 16, 17) is supported so as to be able to vibrate. The torsional vibration damper (1) is primarily characterized in that the energy storage element (15, 16, 17) is arranged such that a vector component (18) acts in the circumferential direction (19) and/or for each intermediate element (6, 7, 8), solely the first rolling body (9) and the second rolling body (10) are provided as the rolling bodies. The torsional vibration damper proposed here allows an inexpensive and efficient influence on the natural frequency to be achieved using few components.

Description

technical field [0001] The invention relates to a torsional vibration damper with an axis of rotation for a power train, which has at least the following components: [0002] - input side; [0003] - output side; [0004] - one or more intermediate elements in the torque transmission connection between the input side and the output side; [0005] - one first rolling body and one second rolling body per intermediate element, said at least one intermediate element each having a transmission path for rolling the rolling bodies, the input side and the output side having matching paths complementary to the corresponding transmission paths; [0006] - A plurality of energy storage elements corresponding to the number of intermediate elements by means of which intermediate elements associated with respective energy storage elements are supported in an oscillating manner. The main feature of the torsional vibration damper is that the energy storage element is arranged with a vector...
