Embodiment Construction

[0028] like figure 1 As shown, a torsional vibration damper 10 connected to a rotating member, such as a crankshaft 40, comprises a rotationally symmetric inner member 11 having an axis of rotation Z, and an outer member 12 coaxial with the inner member 11, the outer member 12 being The ring surrounds the inner part 11 . The inner part 11 and the outer part 12 are connected by a plurality of spring assemblies 13 that transmit torque. The spring assemblies 13 divide the space formed between the inner part 11 and the outer part 12 into a plurality of continuous parts distributed on the circumference of the shock absorber 10 . Cavity 14. The space is annular and concentric with the axis of rotation Z. The cavity 14 is filled with viscous medium and is connected through the overflow channel 15 . When the inner part 11 and the outer part 12 rotate relative to each other, the spring assembly 13 is deformed, and the damping medium is transferred through the overflow channel 15 , r...

Abstract

A torsional vibration damper or a torsionally flexible coupling comprises an inner part (11) and an outer part (12) that is arranged in ring shape around this inner part, which arc joined to one another in a torsionally flexible manner by means of spring elements (13.1, 13.2), wherein the spring elements (13.1, 13.2) subdivide a space formed between the inner part (11) and the outer part (12) into a plurality of successive chambers in the circumferential direction of the damper or the coupling, with these chambers being filled with a viscous medium and connected to one another. There are at least two groups of spring elements (13) which have deflection lines that differ in the circumferential direction. In case of a relative rotation between the inner part (11) and the outer part (12), owing to the differences in the deflection lines, there is a strong spatial displacement of the damping medium, so that such a damper or coupling has a high damping potential. The damping action can be influenced by the overflow behavior between the chambers (14), which are connected to one another directly through the spring elements (13.1, 13.2).

Description

technical field [0001] The invention relates to a torsional vibration damper or a torsional elastic connecting shaft. Background technique [0002] The invention relates to a torsional vibration damper or a torsional elastic connecting shaft, which is composed of an inner part and an outer part, wherein the outer part is annular and is surrounded by the outer periphery of the inner part, and the two parts are flexibly twistable through a spring assembly are connected in a manner in which, in the circumferential direction of the damper or connecting shaft, the spring assembly divides the space formed by the inner and outer parts into a plurality of continuous cavities filled with a viscous medium and interconnected with each other. When there is relative rotation between the inner part and the outer part, the viscous medium is transferred in the cavity to dampen vibrations. [0003] This type of torsional vibration damper is mainly used in the transmission system of large, l...
