Adjustable roller dynamo with torsion spring |
摘要 |
An external-rotor dynamo for the rear wheel of a bicycle is pivotable about an axis parallel to its axis of rotation. The rotor is pressed toward the wheel rim by a helicoidal torsion spring secured along the axis of rotation in separate bearings. One of these bearings is angularly adjustable via a quick-acting but releasable ratchet.
