Embodiment Construction

[0031] Figure 1a A device 1 for damping vibrations according to the invention, in particular in the form of a rotational vibration damper or torsional vibration damper, is shown in a schematic simplified illustration. The device according to the invention for damping vibrations is designed as a multi-stage series-parallel damper 2 . The device 1 for damping vibrations functionally comprises two damping stages 3 , 4 which are each formed from a damping device—a first damping device 5 and a second damping device 7—and are connected in parallel. Parallel connection here means that the damping devices 5 and 7 are arranged in parallel in the line of force. This line of force is realized in parallel or via the two damping devices 5 and 7 . In this case, according to the invention, the first damping device 5 is designed as a tandem damper, that is to say comprises at least two series-connected dampers 6.1 and 6.2. Series here means that the power transmission takes place in series...

Abstract

The invention relates to a device (1) for damping vibrations, in particular a multi-step series-parallel vibration damper, comprising at least two vibration arrangements (5, 7) that are mounted in parallel, that are arranged in a coaxial manner and each one respectively comprising at least one input part (8, 11) and one output part (10, 12), a first damper arrangement (5) that is configured as a series damper comprising at least two dampers (6.1, 6.2) that are coupled via an intermediate flange (23) and that are mounted in series, and a second damper arrangement (7) that is provided with circumferential backlash. The invention is characterised in that the output part (10) of the first damper arrangement (5) forms a structural unit with the output part (12) of the second damper arrangement (7) and the first and second damper arrangements (5, 7) are arranged in the radial direction on different diameters.

Description

technical field [0001] The invention relates to a device for damping vibrations, in particular a multistage torsional vibration damper comprising at least two parallel and coaxially arranged damping devices, namely a first damping device and a second damping device. Background technique [0002] Devices for damping vibrations, in particular in the form of multistage torsional vibration dampers or torsional vibration dampers, are known from the prior art in various embodiments. When the device is arranged in a drive train, viewed in the direction of the force line, it acts as an elastic coupling between a drive device and a driven device with a coupling provided with the connecting parts forming the device. The device transmits a torque member in a power transmission and at the same time compensates for vibrations. It is also conceivable to implement as a shock absorber. In this case, no torque is transmitted between adjacent connecting parts by means of the device, but onl...
