Embodiment Construction

[0047] figure 1 A perspective view of a shock absorber according to a first embodiment of the invention is shown, wherein the shock absorber is generally designated 10 .

[0048] The shock absorber 10 has an inner carrier 12 around which coaxial mass rings 14 are arranged radially spaced apart. The inner carrier 12 and the mass ring 14 are connected to one another via radially extending spring elements 16 made of elastomer. From figure 1 The radial profile deformation (Radial profile formation) 18 on the inner peripheral surface 15 of the weight ring 14 can be seen. In this context, a radial profile deformation body 18 is to be understood as a ring segment of the counterweight ring 14 in which the counterweight ring 14 changes its inner diameter at least once, ie changes from its smallest inner diameter r to its largest inner diameter R. In other words, in the torsional vibration damper 10 according to the first embodiment, a radially profiled deformation body 18 is formed...

Abstract

The present disclosure relates to a vibration absorber for a drive train of a motor vehicle, including an internal carrier which can be rotated around a rotation axis, a mass ring which is coaxial to the internal carrier and which is arranged at a radial distance from the internal carrier, and a plurality of spring elements which connect the internal carrier and the mass ring to each other. The mass ring has at least one radial profile formation on the inner circumferential surface thereof to provide sliding support in the circumferential direction and is provided with an elastomeric damping layer arranged between the internal carrier and the mass ring, the layer being designed such that the mass ring slides at least in the region of the at least one radial profile formation thereof in the circumferential direction on the internal carrier during a relative rotation.

Description

technical field [0001] The invention relates to a shock absorber, in particular for a drive train of a motor vehicle, having an inner bracket rotatable around a rotation axis, having a counterweight ring substantially coaxial with the inner bracket, and having a certain radial direction to the inner bracket. The spacing is set, and there are a large number of spring elements, which interconnect the inner bracket and the weight ring. Background technique [0002] Such shock absorbers are known from the prior art, for example from DE 43 07 583 C1. In the prior art, there are different solutions for radially supporting the weight ring. For example, DE4307583C1 discloses a rotary vibration damper with a support body and a flywheel ring, the support body and the flywheel ring are connected to each other by six elastic segments. The sectors are made of rubber and are vulcanized on the inner shell face of the flywheel ring and on the outer shell face of the support body. Three h...
