Problems solved by technology

In particular, the symmetry or uniformity of the roller tracks in the axial direction is crucial, so for example integral effects of the manufacturing method lead to problems in terms of operation and durability of torsional vibration dampers
For example, when using the stamping process to manufacture the intermediate element, the entry and exit of the stamping part causes the bearing surface of the rolling element to be uneven in the axial direction
This can have a detrimental effect on the movement of the individual components, since the components (input, output, intermediate elements) may move laterally during operation

Embodiment Construction

[0029] In the description of the figures, the same parts are provided with the same reference numerals. known as figure 1 and figure 2 The torsional vibration damper 1 shown in includes an input part 2, an intermediate element 3, a cam mechanism 4, 5 with a ramp arrangement 6, 7 and a spring arrangement 8 with an energy store 9 arranged at Between the intermediate element 3 and the output member 10 . figure 1 The input part 2 of the torsional vibration damper 1 has a slope 11, such as the cam track of the slope device 6 in preferably two cam mechanisms 4 that are mutually relative to the axis of rotation d of the shaft 17 relatively. Preferably, two mutually opposite intermediate elements 3 and rolling elements 13 form a complete cam mechanism 4 between the input piece 2 and the intermediate element 3, said two mutually opposite intermediate elements each having two complementary to the input piece 2. A ramp 12, such as a cam track of the ramp device 6. When the input pa...

Abstract

The invention relates to a torsional vibration damper (1), in particular for a clutch disc within a powertrain of a motor vehicle, comprising an input part (2) which is mounted about a rotational axis(d) and an output part which can rotate about the rotational axis (d) to a limited degree relative to the input part (2) against the effect of a spring device (8), comprising at least two torque-transmitting intermediate elements (3) which are arranged between the input part (2) and the output part (19) and which are arranged so as to be forcibly moved in a radial direction by means of cam mechanisms (4, 5) in the event of a relative rotation between the input part (2) and the output part (10). The spring device (8) is arranged between the at least two intermediate elements (3). The inventionis characterized in that each intermediate element (3) is designed in two parts.

Description

technical field [0001] The invention relates to a torsional vibration damper, in particular for a clutch plate in a drive train of a motor vehicle, a corresponding clutch plate and a clutch, in particular for a drive train of a motor vehicle. Background technique [0002] In automotive engineering, for example, a torsional vibration damper is known from DE 10 2015 211 899 A1, in which an input part and an output part, which is rotatable to a limited extent relative to the input part, are coupled via an intermediate element and a spring arrangement, arranged such that The spring means are not arranged in the circumferential direction. The intermediate element is arranged centrally in the axial direction. The input must be connected to the friction ring. Formation of such connections is complex and limits the space available for formation and movement of intermediate elements, so that the possible capacity of the torsional vibration damper is limited. It has also been shown...
