Problems solved by technology

However, the disadvantage arises that, despite the lowest stiffness, the rotational vibrations cannot be sufficiently reduced in unbranched chain vibrators, since even down to almost 0, the side axle stiffness of the vehicle belonging to the remaining drive train defines the entire drive train vibration performance

Embodiment Construction

[0022] figure 1 A torsional vibration damping arrangement 30 is shown, which is mounted between the drive device 1 and the transmission device 2 . Here, the torsional vibration damper arrangement 30 essentially consists of a rotating mass arrangement 40 which is rotatable about the axis of rotation A and which is not rotatable about the axis of rotation A but is positioned in a fixed position, for example in the luggage compartment of a motor vehicle (not shown here). The damping assembly 50 in the composition. The rotating mass assembly 40 here consists of a primary inertial element 4 and a secondary inertial element 5 , which are rotatable relative to each other against a fixed stiffness 14 here in the form of a steel spring. Furthermore, the rotating mass assembly 40 includes a squeezer unit 6 , which consists in particular of a housing element 60 , a squeezer piston 62 and a working chamber 61 with a volume V1 . In this case, housing element 60 of extruder unit 6 is conn...

Abstract

The invention relates to a torsional vibration damping assembly (30) for a drive train of a motor vehicle, comprising a rotational mass assembly (40) that can be rotated about an axis of rotation A. The rotational mass assembly (40) comprises a primary inertia element (4) that can be rotated about the axis of rotation A, a secondary inertia element (5), which can be rotated in relation to the primary inertia element (4) against the action of an energy store (23), and a displacing unit (6) having a working chamber (61). The displacing unit (6) is operatively connected to the primary inertia element (4) or to the secondary inertia element (5) on one side and to a damping mass (17) on the other side.

Description

technical field [0001] The invention relates to a torsional vibration damping assembly for a drive train of a vehicle comprising a primary side drivable in rotation about an axis of rotation and couplings coupled to the primary side via a working medium for rotation about the axis of rotation and relative to each other secondary side. Background technique [0002] A torsional vibration damping assembly of this type is known from document DE 10 2006 061 342 A1, in which the primary side and the primary side are coupled to the primary side via a damping fluid assembly for rotation about an axis of rotation and relative to each other. , wherein the damping fluid assembly includes a first damping fluid with less compressibility in the first damping fluid chamber assembly that transmits torque between the primary side and the secondary side, and The second damping fluid with relatively high compressibility loaded in the second damping fluid chamber assembly when the pressure of ...
