Abstract
A torsional damper comprises first and second damper elements resiliently coupled by a spring arrangement, and a friction generating device. The friction generating device includes a plurality of friction blocks received in a plurality of windows, respectively, of the second damper element with play in the circumferential direction of the second damper element. The plurality of friction blocks are biased against a radially extending wall of the first damper element by a spring(s). For avoiding undesired interference engagement with the second damper element, the friction generating device includes a pair of axially opposed guide grooves for restricting radial mobility, with respect to an axis of rotation of the torsional damper, of the plurality of friction blocks.
