Patent ID: 8057311

Claim:
A sliding block ( 40 , 42 , 44 ) for a torsional vibration damper including at least one spring element, the sliding block ( 40 , 42 , 44 ) comprising: a first surface section ( 64 ) that operatively faces an adjacent one of the spring element, is harder than another surface section of the sliding block ( 40 , 42 , 44 ), has at least one of first and second supporting surfaces ( 66 , 68 ) for radial support of the spring element, and has at least one of first and second supporting surfaces ( 70 , 72 ) for axial support of the spring element; a second surface section ( 74 ) that has a sliding surface ( 76 ) for sliding support of the sliding block ( 40 , 42 , 44 ); and a basic body ( 50 ) that includes plastic, wherein at least one of the first and second surface sections ( 64 , 74 ) is formed by at least one first insert ( 78 , 80 , 82 , 84 , 90 ) that is harder than the plastic and the first surface section ( 64 ) is formed by at least two elongate second inserts ( 86 , 88 ) 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.
