Torsional vibration damping unit, has grinding unit with ring-like unit, which is axially deformed between two grinding surfaces, so that grinding surfaces stay in grinding contact with grinding material that is sprayed on energy storage

摘要

The damper has spring and grinding units (19, 20) provided between an input part and output part. The grinding unit comprises an axial deformed ring-like unit, which consists of a plate spring-like ring-formed energy storage, which serves as a carrier for grinding material. The ring-like unit is axially deformed between two grinding surfaces, so that the surfaces stay in grinding contact with the material, which is sprayed on the storage.
