Abstract
An actuating mechanism for a multispeed cycle hub comprises a housing adapted to be attached to an end of a hub shaft. A first cam, a second cam, and a pinion having engaging teeth are received in the housing for conjoint rotation. An elongated rack element is mounted for movement along an axis in the housing and is adapted to be coupled to a speed-selection device by a force-transmission member and includes a row of teeth in driving engagement with the engaging teeth of the pinion. A first pivot lever is pivotally mounted in the housing in constant contact with the first cam so as to follow a pivoting motion defined by the shape of the first cam and engages one of two speedchange elements, which are coupled to the transmission in the hub, so as to move the first speed change element upon pivotal movement in response to rotation of the first cam. A second pivot lever is pivotally mounted in the housing in constant contact with the second cam so as to follow a pivoting motion defined by the shape of the second cam and engages the other of the two speed change elements so as to move the second speed change element upon pivotal movement in response to rotational movement of the second cam.
