Torsion damping device having circumferentially acting resilient members of different stiffness
First Claim
1. A torsion damping device disposed between two rotating elements, namely an input element (1) and an output element (2), said device comprising, firstly, a first damper (10), having circumferentially acting first resilient members (11) the first damper being directly acted on kinematically by the input element, and, secondly, a second damper (20), having circumferentially acting second resilient means (21) and being less stiff than the first resilient means (11), the second damper being disposed directly upstream of the output element (2), wherein said device includes a third damper (30), which is disposed kinematically between the first damper (10) and the second damper (20), being arranged radially, firstly, mostly outwardly of the second damper (20), and, secondly, inwardly of the first resilient members (11), said third damper (30) comprising circumferentially acting third resilient members (31) referred to as third resilient members, the stiffness of which is intermediate in value between the stiffnesses of the first resilient members (11) and second resilient members (21) respectively.

Abstract
A torsion damping device is disposed between two rotating elements, namely an input element (1) and an output element (2), the device comprising, firstly a main damper (10) referred to as a first damper and having circumferentially acting first resilient member (11), the first damper being directly acted on kinematically by the input element and secondly, a second predamper (20) having circumferentially acting second resilient members (21), the second damper being placed directly upstream of the output element (2). The device further includes an intermediate third damper (30) which is disposed kinematically between the first damper (10) and the second damper (20), the third damper (30) includes circumferentially acting third resilient members (31) the stiffness of which has a value intermediate between the stiffnesses of the first resilient members (11) and second resilient members (21) respectively.
