BESCHLEUNIGUNGSABHÄNGIGE KUPPLUNG MIT DOMINIERUNGSFÄHIGKEIT

摘要

A clutch selectively transmits torque and rotary motion from a spindle having an axis of rotation to a drum. First and second shoe members disposed radially between the spindle and the drum move radially with respect to the axis of rotation between an engaged position and a disengaged position with respect to the drum. The first and second shoe members are responsive to acceleration for moving into the engaged position and responsive to rotational speed for moving into the disengaged position. A biasing spring normally maintains the first and second shoe members in the disengaged position when the spindle is at rest.
