Abstract

A torsional vibration damper with at least two parts that are rotatable about an axis and can turn relative to each other against the opposition of at least one coil spring. Support shoes are provided between the spring and an outer wall of the damper structure and are arranged to slide along the outer wall with the spring as it undergoes compression and relaxation. The support shoes include roller bodies to reduce sliding friction between the support shoes and the outer wall.
