Embodiment Construction

[0020] figure 1 An application example for the torsional vibration damper 1 according to the invention is shown in a schematic diagram. The torsional vibration damper is arranged in the clutch housing 2 and is connected downstream of the clutch device 3 for closing the power flow. The clutch device 3 is coupled in a known manner to an output shaft of an internal combustion engine (not shown), the torque of which is transmitted via the clutch device 3 to the torsional vibration damper 1 in a known manner. For this purpose, the torsional vibration damper has a drive part 4 , which is rotatable about a common axis of rotation, which rests via an internal toothing on a corresponding shaft leading to a transmission (not shown). Connected downstream of the torsional vibration damper 1 is a torque converter device 5 , which is also only schematically shown here. The basic construction of such an arrangement and its function are sufficiently known.

Abstract

A torsional vibration damper comprising a drive member (4) rotatable about an axis of rotation and coupled to the drive member via at least one spring element resisting relative movement of said spring element relative to said drive member (4) about said axis of rotation Torsional damper mass (8), wherein a spring element embodied as a leg spring (7) is coupled with one end in a rotationally fixed manner to the drive element (4) and passes with the other end on at least one guide rail Coupling rollers (11) rolling on (10, 16) are coupled to the buffer mass (8), wherein the guide rails (10, 16) are asymmetrical so that the leg springs (7 ) is deformed to different degrees when moving out of the zero position (N), depending on the direction of movement of the coupling roller (11).

Description

technical field [0001] The invention relates to a torsional vibration damper comprising a drive element rotatable about an axis of rotation and a damper mass coupled to the drive element via at least one spring element and resisting the opposing spring element around the axis of rotation Twist on the drive. Background technique [0002] Such torsional vibration dampers are used in torque-transmitting arrangements for damping or damping possible torsional vibrations, which involve so-called spring-mass dampers. Such a torsional vibration damper is arranged, for example, in the drive train of a motor vehicle to damp possible torsional vibrations which are usually system-inherently introduced into the drive train by the internal combustion engine. [0003] Such torsional vibration dampers generally consist of a drive part that is rotatable about an axis of rotation and carries a torque, and a damper mass that can be twisted relative to the drive part about the axis of rotation...
