Abstract
A torsional damper comprises damper elements which are resiliently coupled by a spring arrangement and a friction generating device. One of the damper elements has a radially extending wall. The friction generating device includes a plurality of friction blocks received by the other damper element with play in the circumferential direction, and a spring arranged to bias the plurality of friction blocks against the radially extending wall. In order to absorb the shock of engagement of each of the plurality of friction blocks with the other damper element, a cushion is provided.
