Patent ID: 7204772

Claim:
A torsionally flexible coupling comprising a hub ring; a vibrationally isolated pulley surrounding the hub ring at a radial distance; a spring body made of a rubber-elastic material being situated in a gap formed by the distance; and a sliding-contact bearing for mutual support of the hub ring and the pulley, the sliding-contact bearing having a sliding-contact surface and at least one cam on a side facing the hub ring or the pulley, the sliding-contact surface having at least one elastically flexible projection in the radial direction, the at least one projection contacting a surface of the hub ring or the pulley under elastic prestress, the cam being designed as an anti-twist element in a rotationally fixed engagement with an elastic receptacle, the elastic receptacle being situated between the pulley and the sliding contact bearing in the radial direction or between the hub ring and the sliding contact bearing.
