Embodiment Construction

[0023] figure 1 A front view of a partially assembled clutch disk 1 with a torsional vibration damper 3 is shown. In principle, the torsional vibration damper can also be used outside the clutch disc. combine figure 2 and image 3 It is clearly visible that the torsional vibration damper 3 has a torque input disk 5 which carries a friction lining 7 . On this torque input disc 5 , for example, the torque of the drive motor is transmitted via a clutch housing (not shown) to the friction linings.

[0024] The torque input disc 5 has a window-like recess 9 in which at least one spring energy store 11 , for example a helical compression spring, is arranged. In this example, a support disk 13 is inserted between the end turn of the helical compression spring and the notch 9 .

[0025] The torque input disk 5 is centered on its inner diameter relative to the torsional vibration damper hub 15 . By way of example, the torsional damper hub 15 is designed as a split, in which the ...

Abstract

A torsion damper with at least one torque input disk and at least one torque output disk, wherein the torque input disk can move in circumferential direction relative to the torque output disk against the force of at least one spring storage, wherein the relative movement is damped by a friction device which generates a smaller friction torque in a first swivel angle range than in a second swivel angle range in that the friction device has at least two friction ring pairs which are rotatable opposite one another and which are activated depending on the swivel angle via a driving connection of at least one friction ring with the torque input disk. The driving connection has a spring element which is arranged functionally in series with the friction device and functionally in parallel with the spring storage.

Description

technical field [0001] The invention relates to a torsional vibration damper with a swivel angle-dependent friction device. Background technique [0002] The problem of premature failure is not uncommon with friction devices in general. Most friction devices operate with a constant friction torque / constant damping over the entire characteristic curve of the torsional vibration damper or are adapted to a characteristic curve region or a spring stage. For this purpose, for example in DE 10 2007 006 381 A1, the control lug engages in the spring window or at least has a control edge for the spring. However, the magnitude of the required friction torque is only determined by the required damping of the drive train resonance in the individual gears of the gearbox. The greater the resonance, the greater the required damping (=friction torque) and thus the greater the load on the friction device. In the usual sense, a load is a greater force (mostly a coil spring) at the contact ...
