摘要：A transmission apparatus for changing the speed of a driven member relative to the speed of a driving member without interrupting the torque transfer between the members. The apparatus includes reducing gears driven by a driving member, annular cam gears in continuous engagement with the reducing gears, and a driven member which journals the cam gears for rotation. One section of the driven member is hollow and has a plurality of radially extending apertures each containing a reciprocating detent for engaging an inner cam surface or a corresponding cam gear. A shift member mounts within the bore of the driven member and moves along the rotational axis of the driven member to cause the detents to reciprocate between a cam gear engaged position and a disengaged position. By timing the movement of the shift member and the design of the cam surfaces on the cam gear, one cam gear can be simultaneously engaged while another is being disengaged to produce a gear ratio change without interrupting torque transfer between the driving and driven members.
