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

    摘要: A belt tensioning unit (1) having a rotatably fixed base part (2) and a tensioning part (3) which can be rotated in a limited manner in relation to the base part against the action of an energy storage unit (6) is provided. Between the base part (2) and the tensioning part (3) a friction device (8) is radially arranged between the energy storage unit (6) and a friction surface (10). The friction device is pre-tensioned by the energy storage unit (6) in a radial outward direction against the friction surface (10) when the base part (2) and the tensioning part (3) are rotated in relation to each other. In order to obtain a simple friction device (8) having improved friction properties, it is proposed to design the friction device (8) as a friction segment (9) that encloses two friction surfaces arranged symmetrically to each other and opposite of each other at the friction surface (10).
