摘要

The oscillation decoupling device is provided with a pulley (1) for receiving a belt, and a drive shaft (2) rotated with the pulley, where a coupling device connects the pulley with the drive shaft. The coupling device comprises a freewheel element (3) and an elastomeric spring body (4). The hardened mating surfaces (5,6) are associated with the freewheel element. The former mating surface is assigned to the pulley. The latter mating surface is assigned to the elastomeric spring body.
