摘要： The invention relates to a traction mechanism
drive, in particular for an internal combustion engine, comprising a vibration damper (1) having a base part (2) and a rotary part (3) that can be rotated to a limited extent relative to said base part against the effect of an energy store (6), wherein between the base part (2) and the rotary part (3), a friction unit (8) having a friction ring (9) comprising a support element (15) and a sliding element (16) arranged radially outside of the support element (15) for forming a friction contact in relation to a friction surface (10) is effective. According to the invention, the friction ring (9) is produced in one piece from the support element (15) and the sliding element (16), wherein the support element (15) and the sliding element (16) are cast on top of each other and a positive fit (17) is effective between said support element and sliding element in the circumferential direction.
