  • Shift drum having an insertion-groove flank movable axially with respect to a shift drum axis and shifting method
    Patent number: 7363834
    Abstract: Shift drum (10; 10?) for a multi-step transmission of a motor vehicle, with at least one circumferential track (14, 16), in particular circumferential groove (14, 16), into which at least one axially displaceable track follower (S, T) can engage, the circumferential track (14, 16) having flanks (22, 24) along which the track follower (S, T) is guided, characterized in that one of the flanks (22) has a portion (26) which is mounted so as to be movable axially out of a normal position against a restoring force (FR).

  • Sensor arrangement for determining selector drum position
    Patent number: 6730864
    Abstract: A sensor arrangement (10) for determining the selector drum position of a selector drum, in particular of a transmission controller, having a sensor disc (11) that is operatively connected to the selector drum and identifies different selector states by means of a running track (14), and a sensing device (12) that continuously senses the running track (14) in order to register the position data from the running track (14) which identifies the switching states.
