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.

Torsional vibration damper

The coaxial first and second flywheels of a torsional vibration damper, e.g., in the power train of a motor vehicle, are rotatable relative to each other against the opposition of one or more arcuate coil springs which is or are confined in an annular chamber defined by at least one of the flywheels. One end of the coil spring or each coil spring bears, directly, or indirectly, against a single retainer or against one of several discrete retainers on one of the flywheels, and the other end of the coil spring or each coil spring bears, directly or indirectly, against a single retainer or against one of several discrete retainers of the other flywheel. At least one slide is interposed between the radially outermost portions of discrete convolutions provided between an internal surface of the at least one flywheel and one or more discrete coil springs, one for each slide. The slides are clamped to selected convolutions of the respective coil springs against lengthwise and/or radial movement away from the respective coil spring or springs.
