Problems solved by technology

[0003] When trying to provide a cost-optimized torsional vibration damper without U-shaped channels, since the side walls of the channels are omitted, the spring element can only be supported on one side in the axial direction, and thus the azimuthal aspect of the turns arises problems, whereby the turns of the spring element can move relative to each other and the spring element can be damaged under torque peaks

Embodiment Construction

[0018] figure 1 A torsional vibration damper 1 is shown in half section with an input part 2 and an output part 3 , wherein the torsional vibration damper 1 is arranged rotatably about an axis x-x. The torsional vibration damper 1 is designed, for example, as a dual-mass flywheel, clutch damper or other torsional vibration damper.

[0019] The input part 2 is arranged in a rotatable manner relative to the output part 3 . In this case, the input part 2 can be mounted so as to be rotatable relative to the output part 3 , for example by means of a bearing 4 . The bearing 4 , which is designed, for example, as a rolling bearing or sliding bearing, rests radially against the annular shoulder 5 of the input part 2 and radially against the annular shoulder 6 of the output part 3 . Alternatively, this can also be reversed.

[0020] A spring damper 7 is provided with a spring element 8 which is designed, for example, as an arc spring. The spring damper 7 has a spring element 8 whic...

Abstract

The invention relates to a torsional vibration damper (1) with an input part (2) and with an output part (3). The input part (2) is arranged so that the input part can rotate relative to the output part. The torsional vibration damper also comprises a spring damping device (7), which is arranged between the input part and the output part in the torque flow. The input part can rotate relative to the output part against the restoring force of the spring damping device. The input part is provided with a pocket (9), which is opened in an axial direction and is used for receiving spring elements (8) of the spring damping device. A flange (12) connected to the output part is also engaged in the pocket. On one hand, the spring elements are supported on the input part in the circumferential direction, and on the other hand, the spring elements are supported on the flange for transmitting a torque from the input part to the output part. A ring element (14) is connected to the output part and has a region (15) which is cocked in the axial direction and serves as a restriction of the space (16) of the pocket.

Description

technical field [0001] The invention relates to a torsional vibration damper, in particular for a drive train of a motor vehicle. Background technique [0002] Torsional vibration dampers with an input part, an output part and a spring damper are known. Here, the spring element is used, for example, in the form of an arc spring which is arranged in an annular channel of the input part which is open radially inwardly, wherein the flange element of the output part engages radially from the inside. The spring element is supported in the circumferential direction on the stop of the input part and on the flange element and transmits torque between the input part and the output part. The design of the U-shaped channel of the input part here also allows an axial support and a radially outer support, so that the orientation of the respective spring element and thus the turns of the spring element are very well defined. Orientation so that the spring element can safely transmit tor...
