Embodiment Construction

[0024] figure 1 A torsional vibration damper 100 for use in a motor vehicle powertrain is shown. The torsional vibration damper 100 is mounted rotatably about the axis of rotation 105 and comprises a pendulum flange 110 and three pairs of pendulum masses 115 which are distributed on the pendulum flange 110 around the axis of rotation 105 . Each pendulum mass pair 115 includes a first pendulum mass 120 and a second pendulum mass 125 , as well as a pin 130 and a spring element 135 . The first pendulum mass 120 and the second pendulum mass 125 lie flush with each other on different axial sides of the pendulum flange 110 so that figure 1 The rear second pendulum mass 125 is not visible. The pin 130 rigidly connects the first pendulum mass 120 and the second pendulum mass 125 to one another. In this case, the pin 130 passes through a recess 140 in the pendulum flange 110 , which is dimensioned such that the pendulum mass pair 115 remains displaceable on the pendulum flange 110 i...

Abstract

A torsional vibration damper (100), comprising: a pendulum flange (110) with a notch (140) capable of rotating around an axis of rotation (105) and two pendulum mass pairs (115), which are aligned in the circumferential direction Adjacently, movably arranged on the pendulum flange (110); and first and second elastic elements (135), used for buffering mutual stops of adjacent pendulum mass pairs (115). Here, the pair of pendulum masses (115) each comprise: a first and a second pendulum mass (120, 125), which are opposite each other with respect to the pendulum flange; and a pin (130), which passes through the recess (140) extends and axially connects the pendulum masses (120, 125) to each other. On the two pins (130) in the region of the notch (140) are respectively arranged a first and a second spring element (135), the first spring element being arranged to stop at the corresponding first spring in the circumferential direction. On the two elastic elements (135).

Description

technical field [0001] The invention relates to a torsional vibration damper, especially for use in a powertrain of a motor vehicle. Background technique [0002] Torsional vibration dampers are used for the transmission of torque in the drivetrain, for example from the drive motor to the transmission. The purpose of the torsional vibration damper is, in addition to transmitting the torque, to eliminate torsional vibrations (torsional vibrations) which may be superimposed on this torque. For this purpose, the torsional vibration damper includes a pendulum flange, on which a pendulum mass is displaceably arranged. By means of the link guide, the pendulum mass is guided on the pendulum flange in such a way that the pendulum mass moves radially inward when the pendulum flange is accelerated about its axis of rotation, wherein the rotational torque of the torsional vibration damper is changed. In a refinement, the pendulum mass is a trapezoidal pendulum which is guided doubly ...
