Abstract
A first flywheel and a second flywheel in a flywheel assembly are configured to be connected to each other such that they rotate together with generally no relative rotation therebetween in a predetermined low RPM region. The flywheel assembly (1) includes the first flywheel (2), the second flywheel (3), a damper mechanism (5) and a lever mechanism (7). The second flywheel (3) is disposed rotatably relative to the first flywheel (2). The damper mechanism (5) elastically connects the first flywheel (2) and the second flywheel (3) to allow for limited relative rotary displacement therebetween. The lever mechanism (7) is mounted on the first flywheel (2) and pivots about a pivot bolt connected to the first flywheel (2). The lever mechanism (7) pivots between an engaged state and a disengaged state. In the engaged state, the lever mechanism (7) connects the first flywheel (2) and the second flywheel (3) such that the two flywheels may not undergo relative rotary displacement with respect to each other. The lever mechanism (7) moves to the disengaged state in response to rotation of the flywheel mechanism at a rotational speed greater than a predetermined RPM.
