Freewheel for pulley, has sliding movement device arranged slidably on secondary side, and two parallel-connected disk springs provided with different spring characteristics, where secondary side is rotatable relative to primary side

摘要

The freewheel (30) has a secondary side (3) rotatable relative to a primary side (2) about a rotational axis. A sliding movement device (21) is arranged slidably on the secondary side and rotatable relative to the secondary side. Two parallel-connected disk springs (16, 20) are provided with different spring characteristics. A connection plate (17) is supported by the sliding movement device in an axial direction. Twisting angle limiting unit is relatively twisted between the connection plate and the sliding movement device. An independent claim is also included for a pulley.
