Belt pulley rotary speed and/or torque variation reducing device for belt drive of internal combustion engine of motor vehicle, has springs with middle section clamped by dogs, where number of dogs corresponds to number of springs

摘要

The device (1) has leaf springs (9) with journal ends (10, 11) mounted tangential to an inner lateral surface (12) of a circular housing (4) in a non-positive manner. A middle section of the leaf springs is supported at a polygon (14) connected with a hub (5) in a torque-proof manner and is clamped by dogs (15) formed at the polygon, where the number of dogs of the polygon corresponds to the number of leaf springs.
