Abstract
A torsional vibration damper includes at least one spring element and a sliding block. The sliding block includes a first surface section that operatively faces an adjacent spring element, is harder than another surface section of the sliding block, has first and/or second supporting surfaces for radial support of the spring element, and has first and/or second supporting surfaces for axial support of the spring element. A second surface section has a sliding surface for sliding support of the sliding block, and a basic body includes plastic. The first and/or second surface section(s) is/are formed by at least one first insert that is harder than the plastic. The first surface section is formed by at least two elongate second inserts that are spaced apart from one another and projected and on which the spring element can be supported in a centering manner in a radial direction.
