Belt drive clamping device for internal combustion engine of motor vehicle, has integrated multi-functional part arranged in housing part, and damper designed as frictional damper with frictional partners

摘要

The device (1) has an integrated multi-functional part (10) arranged in a housing part (3). A torsion spring (20) is formed as a legless coil spring, which produces a rotary force connection between the parts (3, 10) on a side turned towards the part (3), and is attached to a spring fracture safety device. An expansion element (9) is axially arranged at a distance between the housing part and the clamping arm, and is arranged on a side turned towards the clamping arm. A damper is designed as frictional damper with frictional partners (11, 12) working together in a radial direction.
