Title:
TORSIONAL DAMPER
Document Type and Number:
WIPO Patent Application WO/2019/178745
Kind Code:
A1
Abstract:
A torsional damper (100, 200, 300) is provided, wherein a primary mass (20) and a channel cover (70) are fixed together on the outer periphery. In an axial direction of the torsional damper (100, 200, 300), at least part of a support ring (90) is disposed between the primary mass (20) and a flange (40). The flange (40), a diaphragm spring (60), and a secondary mass (50) are fixed together. The diaphragm spring (60) is located between the flange (40) and the secondary mass (50) and elastically presses against the channel cover (70), wherein the support ring (90) comprises a regulating support ring (92) and a fixed support ring (91) that supports the flange (40). An axial cross-section of the regulating support ring (92) is wedge-shaped. When the pressure between the flange (40) and the primary mass (20) reduces as a result of abrasion and/or the plastic deformation of the diaphragm spring (60), the regulating support ring (92) moves under the influence of centrifugal force towards a radial outer side of the torsional damper (100, 200, 300) with respect to the fixed support ring (91), so as to maintain or enlarge an axial distance between the primary mass (20) and the flange (40) and make the spring force of the diaphragm spring (60) remain substantially constant.
